Title: Is there a way to rollback to a stock rom without "unlocked" icon on XT910?
I'm looking forward to install new CM 10.1.3 to my Razr MAXX (XT910), but I see some bug reports about this version. I want to give it a try, but - is there a way to go back to the stock ROM if I don't like it? By "go back" I mean restoring it's original state, no "unlocked" icons.

Currently I have 982.124.14.XT910.Retail.en.FR (Android 4.1.2).

# Answer
The lock icon when you turn on your phone shows that the phone's bootloader is unlocked and doesn't show if it's rooted or not.

Just use the tool to you used to Root and unlock the bootloader to unroot and re-lock the bootloader it.

For info about the Razr XT910 have a look at this link

> By flashing a ROM or rooting your Razr voids Motorola Warranty Terms. Even if you flash the same rom your Razr came with. 3. All the devices are divided by regions. This means you can only flash a stock ROM designated for your Razr region. Common Regions are: Latam (Latim America 'n Canada) - Europe - Asia - PSHAsia - ME - China - Korea - Japan(\*

The Galaxy Fame has a micro SD card and by default photos and videos are saved there. Just plugin the card to any PC via a reader and you should have the photos and videos.

Title: boot.img doesn't contain source code
I have a MTK soc phone rocking JB 4.2.2 with kernel 3.4.0. I have extracted the boot.img in Ubuntu using dsixda kitchen, however the extracted boot.img folder doesn't contain C source code. I have searched on Internet but didn't get any solutions.

C source code is compiled into executable code. There's very little need for C source code files to exist on Android devices.

If you want Linux kernel source you need to head over to Kernel.org.

Title: Correctly adding movies to a Nexus 7
I recently got a Nexus 7 (this year's model), and I can't seem to be able to add movies to it properly. I dragged a bunch of directories, each containing a video file and a subs file to the Movies directory in /sdcard, but they aren't recognized properly by the default movie player (Google Play Movies). Instead, they show up in the gallery. The formats are either mp4 or mkv (x264 with ac3 or aac).

Where should the files go so they don't show up in the gallery and do show up in the movie player?

# Answer
You may need to install an app to play these movies. As mentioned by eldarerathis, the Play Movies app doesn't play local content, only shows/films downloaded via Google Play.

MX Player, VLC and MoboPlayer are popular media playing apps. Personally I use MX Player.

Title: How to reset my phone without deleting the game data?
I need to know please how can i reset my android 4.1.2 symphony xplorer without deleting it's game data

# Answer
> 3 votes
That would be a contradiction in terms: to be a "reset", it has to delete *all* your data. What you need to do is back up your game's data first, then do the factory reset, then reinstall the game, and finally restore the game's data from a backup.

This is easiest to do if your device is rooted: you can use a backup app such as Titanium Backup to backup and restore any app's data.

If you don't have root, then other apps can't access your game's data to back it up. If the game supports Google's automatic cloud backup, then that will work without you doing anything (though it's known to be buggy on some devices, when the manufacturer or carrier has customized/replaced the *backup transport*).

If the game doesn't support that, or you can't or won't use Google's backup for whatever reason, you can still back it up using `adb`, by following these instructions.

# Answer

Many games generate files to save settings/records/step, so you can copy that files on the pc and put on the device after the reset

Title: How do I manually enter Clockwork ROM Recovery?
I have Droid 2 Global (droid2we) and I've tried Power + Volume Up, but that doesn't load any recovery mode. I've also tried Power + X but that loads the standard Android System Recovery \<3e\>, which won't install unsigned zip files.

I can load the Bootstrap Recovery app which will let you reboot into Clockwork Recovery mode, which does work. However, that requires a functioning system which makes it a pointless way to launch a recovery mode!

# Answer
> 0 votes
I found that the following sequence works:

1. While on, run `adb reboot recovery` from command line. This will restart into standard Android recovery. (If your device is not seen, start at #2 and come back.)
2. Take battery out.
3. Unplug USB.
4. Hold power down for 10 seconds. (Someone theorized it discharges the capictors.)
5. Plug USB cable in.
6. Put battery in. This starts the phone up automatically for some reason. It then loads Clockwork Recovery automatically.

I don't know why this works and Clockwork Recovery didn't provide a standard method to start. This would work in the middle of a failed install of Cyanogenmod. After a flash to a stock SBF ROM, it no longer worked.

These are the steps to boot your Droid 2 phone into Recovery Mode should you need to.

1. Turn Droid 2 Off
2. Press 'X' on the physical keyboard and then Press and HOLD Power button until the Exclamation Point/Android picture shows(after motorola symbol).
3. To access menu options Press the "Search" button depicted by the Magnifying glass on the Keyboard and the menu items will show up.
4. Browse options with the Volume Up and Volume Down keys and select option with the Camera button all on side.
5. Select first option of "Reboot phone" or risk messing up your brand new Droid 2!

EDIT:- the link to XDA forum that explains you problems

Here's one more experience for anyone looking this up: I can get CWM recovery to boot from ROM manager, but attempting to boot it manually by holding down x didn't seem to work. I got the exclamation mark mentioned here, but the search button did nothing to bring up a menu. However, doing all of this with a USB cable plugged it, then getting all the way to the exclamation mark, I pulled the battery while still plugged in, just for a second or two, then put the battery back in. It automatically rebooted correctly into recovery without the exclamation mark. This is on a Droid 2 Global running various different versions of CWM recovery.

EDIT:or of course, from the link in another answer here, try up and down volume at the same time instead of search button.

Title: How to prevent applications to donwload data automatically?
I have many applications installed on my Samsung Galaxy Tab 10.1. And it always download something from internet, in order to update and upgrade applications. It does it all the day and night, when I am in my home or business WiFi and when I am in mobile network.

How to disable this "feature"? I don't want any blind upgrades, only by my explicit permission.

Also, of course, I don't want to replace numerous downloads with numerous asks for permission.

This is part of Google Play Store settings. Select Do not auto-update apps in the following path: Google Play Store\>Settings\>Auto update apps\>Do not auto-update apps

This is a global setting, but it may be overridden by a specific setting at the application level. For instance, an application may have a specific setting to update itself, especially if that application came from a 3rd party source. You will need to check those application settings individually and prevent auto-updating there. However, this is not generally true, in fact I think it is a violation of terms, if that application comes from the Google Play Store.

Title: Syncing between Windows 7 and Android Jellybean with Winamp
I want to sync my Samsung Galaxy S3 4G to my Windows 7 PC with Winamp so I can easily sync playlists to and from my phone and computer. So I followed the instructions in Winamp's official blog: http://blog.winamp.com/2010/11/30/wirelessly-sync-music-to-your-android-phone/

It didn't work. When I click on the Discover button, nothing happens. When I right-click Devices and click Start Discovery... you guessed it - *nothing* happens! I am connected to a windows domain and connected via an Ethernet cable. Could that be preventing me from accessing the same WiFi network I have my Galaxy on?

I've done some research on this issue and it is a common problem. If anyone has found a solution to it, I'll be very glad to hear it! I love using Winamp and don't want to use any other media player.

# Answer
I know this is an old thread and you may have already found an answer, but I had the same problem after installing Winamp 5 pro on an Android device. I had previously had no problems with Winamp standard on both Android & PC

I upgraded the PC version to Winamp Pro and now it all works as expected again. So I suspect you need the same version of Winamp on both platforms ie. either standard or Pro
> 1 votes

# Answer
After some look-ups, I have to come into conclusion that you *cannot do this*. As you thought it's your Ethernet connectivity that prohibits you from this. When you are using the ethernet-connected modem device for WiFi, there is only *one* device in your WiFi network. But Winamp says, *`Make sure your PC and Android phone are on the same Wi-Fi network.`*

Note: If you really need this syncing feature, you can get a WiFi adaptor and connect your PC *and* phone to the same network and do syncing

Title: Deleting or listing least frequently played songs in Google Play Music
I'm starting to hit the limits of my storage space. My device is mostly filled with music, so I'd like to remove songs I don't listen to anymore, without having to painfully scroll down the list and delete them one by one.

Does Google Play Music have some way to at least list the least frequently played songs, or is there an additional music management app I should know about?

No there's no feature in Google Play Music that lets you delete songs you don't listen to. AFAIK there is no app that does the same too.

Title: Sony Xperia L device memory is being eaten up
My phone's /data storage is getting fuller all by itself even though I have not installed much apps. By doing some search on net have found that there are folders under Data folder such as tombstones, thumbnails etc. which are taking up the space but which are not accessible without rooting.

It needn't necessarily be tombstones and thumbnails that takes up your phone's data storage.

Normal app usage (mostly browser cache, etc.) also consumes space over time.

Have a look at

```
Settings->App->All apps

```

then via menu let them **Sort by size** to see the biggest storage consumers.

E.g. my phone's biggest consumer is Chrome (123MB data, 280MB cache):

Free up space on the internal SD card folder.

With Jelly Bean the formerly separate SDcard data is also stored on /data (/data/media to be precise). Free up some space there, it counts to the overall sum on /data.

Reason: /data and the *external storage* partition have been merged to only have *one* partition and benefit from a single storage scales better. It removes the need to choose a reasonable hard partition size split for /data and /sdcard as before. For compatibility reasons, the /data/media folder is exposed via a virtual fuse layer that emulates the former FAT properties and hides the internal structure from apps. Android Police has an interview why this was done here.

Could probably be realized using Tasker:

* Condition: Boot completed (or Monitor Start)
* Task: Start App

Not sure if you can specify a video file directly here. But there might at least be some video player supporting to automatically start playing the latest playlist, which should make up for it.

You can find a free 7-day-trial of tasker on their homepage -- or try alternative automation apps such as e.g. Llama - Location Profiles. Another possibility is to create the profile with *Tasker*, and then export it using the Tasker App Factory; this way you'ld get a "free version app" of your profile to distribute on the tablets.

# Question
Title: How does Android measure connectivity state?
I know Android has some sort of connectivity measurement, because when there's connectivity the wifi or phone network icons will turn either green or blue, depending on the Android version.

In my opinion, this measurement isn't perfect, because although it will indicate accurately the absence of connectivity (e.g., lost wifi connectivity), it is not so accurate when the phone is connected to the Internet: **at work, my Defy running Cyanogen 9 (Android 4.0.4) has icons that are always gray, no matter what, even when the connection is obviously up** (see image below).

I wonder ***how, exactly, Android measures the connectivity status***. Is it by performing a ping or other sort of probing of a server? By listening to a port? By testing if some protocol is enabled? Or what? This accepted answer to a closely related question doesn't seem to answer it.

# Answer
> 3 votes
All of the information about it is pretty vague. Probably because they don't want people attacking a particular Google server.

For instance, the Samsung Galaxy Tab 10.1 owners manual has this to say:

> Note: Network status icons turn blue if you have a Google Account added to your tablet and the tablet is connected to Google services for syncing your Gmail, Calendar events, contacts, backing up your settings, and so on. If you do not have a Google Account or if, for example, you are connected to a Wi-Fi network that is not connected to the Internet, the network icons are gray.

# Question
Title: Does a malicious android WebView break the DoubleSubmittCookie countermeasure against CSRF?
**Initial situation:**

A RESTful webservice defends against CSRF attacks by using the double submit cookie approach. This means that the authentication token gets submitted twice and verified at the service side.

**Problem / Security Threat:**

The WebView element of the android and iOS plattforms allow to create a malicious web browser that unveils and modifies session cookies. **`webView.loadUrl("javascript:document.cookie=’’;");`**. If the attacker already figured out, how the double submitted cookie looks like, (In this case it's the AuthenticationToken) he is able to create a malicious RESTBrowser. Therefore he adds the already known CSRFToken to the document object model and thus bypasses the CSRF countermeasure. Is that right so far?

**Possible Preventions:**

So far I have no idea how I can prevent an attacker from creating und publishing such a malicious mobile application, as well to prevent the service from beeing accessed via malicious mobile applications. I know about the existence of the `User-Agent` header and that the service can use this information to reject requests from others than specific browsers. But I'm sure that also this header can be manipulated within the WebView.

What are effective countermeasures aginst CSRF in contex of malicious mobile applications?

# Answer
> 2 votes
> Does a malicious android WebView break the DoubleSubmittCookie countermeasure against CSRF?

Short answer: no.

Long answer: CSRF exploits the trust that a site has in a user's browser. CSRF protection is not intended to protect the server from a malicious user agent or from an untrustworthy user. The user is responsible for choosing a trustworthy browser.

# Question
Title: Slideshow wallpaper using files in hidden folder
I've got some nice photos in one folder and their specially cropped versions in another hidden folder (the name starts with a dot).

How can I use the cropped photos from the hidden folder for a wallpaper slideshow? No matter what app I try to use, it doesn't allow me to use the hidden photos. I don't want to make them visible; I don't want duplicated photos in my gallery app.

Is there any way / app that would allow me to use the hidden photos for a wallpaper slideshow without having to make them visible in my gallery app?

# Answer

Android treats filenames that start with a dot as hidden. So, there's no way for any app to show them. However, you can still see them on a file explorer that can see hidden files (may need root access).

title: HTC One / Beats Earbud Conflict

text:
# Question
Title: HTC One / Beats Earbud Conflict
The Beats earbuds that came with my HTC One initially worked great: the inline control worked, sounded decent. Recently, the phone fails to recognize them however. When I plug in alternative earbuds the phone plays music through the alts. When I plug the Beats earbuds into alternative audio sources, the earbuds themselves work fine.

There appears to be a conflict between the two together:

* I have tried using the headphone controls apps to see if throwing an app in there dedicated to managing the earbud controls would be a workaround and this did not work.
* When I plug the Beats earbuds in, music plays through the phone speaker but the earbuds make the noise they would due to being plugged into a sound source
* I have tried this with the Beats Audio setting on and off, and it is not a separate volume settings issue as the phone plays music through itself instead of the earbuds
* Essentially, the issue isn't even with the inline controls, it is with audio not coming out at all; having audio come out of them would suffice a win for me

What are my options and which are the best:

* Get a new set of the same headphones; confirm if the issue is with this specific pair, and perhaps a short inline or other wear issue?
* Is there some kind of Software solution?
* Is the phone the problem even if other headphones work with it?

# Answer
# Problem

I have been recently using my beats tour with my HTC One. It was working fine and then it stopped working. First I thought either my phone had a problem or the earphones. I thought of claiming my warranty but, before that I did following tests:

1. Plugged different earphones in my HTC One from Apple, Samsung and HTC. All worked fine.
2. Plugged my Beats earphone with iPhone, iPod and my computer. It was working fine too.

# Analysis

Then I compared the connector of Beats earphone with others. I noticed a potential design flaw with both Beats connector and HTC One:

1. Beats earphone connector radius is slightly smaller than normal earphone connectors.
2. HTC One internal connector was pushed in more when plugging and unplugging earphone.
*(I don't exactly know words to explain this but, this usually happens with electronics when using cheap materials)*.

# Solution

As I am sure both HTC and Beats won't be accepting these facts. I recommend you to buy a short extender. I connected my extender to my HTC One and Beats earphone and it worked like expected.

I am not sure if we lose quality when using a cheaper extender.

# Answer
Strictly speaking as long as you leave the data lines open the behavior depends on the phone *and* the computer you plug it into. Your best option would be hardware-only to make sure that the computer doesn't get to see any of the data.

A recently funded Kickstarter project named LockedUSB aims to provide exactly that, also in light of potentially malicious "charging stations" in public places. I'm not linking it since that may be considered spam and that's certainly not the intent behind this answer. A web search can lead the way to them.

From their description:

> LockedUSB is an small adapter that allows secure charging of your personal devices. It physically disconnects the data lines, while keeping intruders away from your personal information.

With this kind of solution you will also avoid bad surprises when you forget to switch something off in software on the phone and thereby involuntarily expose your device. Aside from that it's a generic solution that will work without software support on either side and gives you the peace of mind you seem to be looking for when charging your device in other peoples' computers.

Disclosure: I am one of the funders of the above mentioned project on Kickstarter.

Title: How to hard reboot the Nexus 7 (2013) when touchscreen is dysfunctional?
I am using the Nexus 7 (2013) with the latest standard firmware from Google and today I encountered a weird problem.

When I turn the device on, the display lights up and all. I can also put it to sleep again. However, the touch screen does not work. Tilting the device also causes the automatic change from portrait to landscape mode and vice versa.

Holding down the power button brings up the "shutdown menu", but since the touchscreen isn't working, I cannot tell it to shut down. For the moment I am left to discharge the battery (it's also not sleeping automatically anymore, so it's faster) until it shuts down by itself gracefully or dies.

Any way of doing a hardware reset?

Connecting via USB doesn't help, because I have USB debugging disabled by default.

# Answer

I'm not 100% sure about the Nexus 7, but with my Nexus 4, you can hold the Power button for a very long time (Something like 20 seconds) and it will hard-shutdown. This should help facilitate a hard reset and let you get into Fastboot or Recovery mode if you need to.

2. On your account profile, tap the Overflow Menu (three vertical dots) in the lower right corner

Ok, I just found out how you can quit skype. Go to the main screen in the app and click the left button. After that click sign out, than you'll be able to quit with the return button. Some have already posted this but I think it wasn't completely clear to people who are new to android (like me) :P

For me 'Sign Out' behaves exactly as on the PC Skype client. i.e. the client keeps running. If you then force it to quit (see below) you will need to enter your password again next time you sign in. Here is a generic way to quit Skype that does not require to install a new task manager or some 'stop skype' app: Go to Settings -\> Applications -\> Manage applications -\> Skype -\> Force stop

They changed it again, it appears (Skype 4.4.0.31835). While previously it could be reached via the Menu button, there is no more option to sign out there.

Instead now you have to press the button with the dashed circle around the avatar, next to the menu button on the main screen of Skype. There you'll see this:

At the very bottom you find the option to sign out, which will also quit the Skype client.

The previous version behaved the way described by the accepted answer (as of this writing). But it didn't get me any further.

I know how to sign out. When you are signed in, HOLD THE HOME BUTTON FOR A LONG TIME ON YOUR ANDROID PRODUCT, NOT IN SKYPE! You will be able to see a button which is Task Manager. Click it and you will see the active applications on your android product. Then press the end button that you see next to the skype logo.

title: Power problems with Droid Incredible 2

# Question
Title: Power problems with Droid Incredible 2
My daughter's Droid Incredible 2 is *mostly* dead.

Symptoms:

* If we can manage to turn it on, it only stays on for a minute or so after it completes all of its start-up tasks. Then turns off and acts like the battery is dead.
* When I plug it in, I usually get a rapidly flashing amber light, rather than the steady amber light (for charging) that I would expect. Usually the flashing seems to slow down and then stop (with the light off). There's no indication that it's charging.

There's no water damage, nor is there any physical damage to speak of. (Just some less-than-normal wear-and-tear.)

I've removed the battery and checked the contacts. They're nice, shiny metal. The battery is seated properly.

Have I got a battery that needs replacing? Does it just need to charge longer before turning on? (I am seeing the same issue with two different phone chargers, including one for my Galaxy Nexus that has no issues.)

Any insights?

# Answer
The Incredible 2 has a defective charging port that does not typically last a long time. It is an extremely common issue with this phone. Chances are, this is what you are seeing.

Disclaimer: I have been using my current dinc2 for ~18 months and haven't had this issue yet, but I did see it on a used phone I attempted to buy. Anyway, my plan for if/when this does happen is:

Repair HTC Incredible 2 USB Charge Port

The part is supposed to be $12 and takes an hour to do. If you're not comfortable doing it yourself, I'd take it to a cell phone repair shop.

title: Safely "unmounting" USB for Galaxy?

# Question
Title: Safely "unmounting" USB for Galaxy?
I wanted to delete all of the music (not pictures or apps) off my phone, and I read that you should just plug it into the computer and delete them from there. I plugged it in, and though my phone is charging, it hasn't recognized my device. I want to unplug it, but there is message warning me to unmount the USB before I unplug. Will it delete all of my memory if I do? Can I just back up and reset my phone while in this mode, or will my things be deleted?

# Answer
> 0 votes
No, nothing will be deleted if you chose to "unmount" first. As your device was not detected, it should not even be mounted, so there's nothing that could "break".

---

A short explanation on that "mysterious unmount", though:

If your device is "mounted" (i.e. you can access its files from your computer), for faster reaction and other performance reasons all data transfered is "buffered" (instead of being written to the storage immediately). So "unmounting" tells the system to "flush" those buffers, and thus "commit" (write) all buffered data to the storage.

If you would simply "plug the line" without unmounting first, not-yet-written data were lost. Imagine what that would mean if some larger file was only written partly (it gets corrupted), or if you *moved* files to the phone which where not yet written at all (they are "lost in space").

So it's always a good safety measure to "unmount" first before plugging out the cable.

# Question
Title: Wired xbox controller not working with LG G2
My boyfriend purchased a USB OTG cable so he can play Android games with an Xbox 360 wired controller. When he plugs the Xbox controller into his LG G2 nothing happens, I plugged it into my Samsung Galaxy S4 and it worked immediately. His LG G2 recognizes a flash drive, keyboard and mouse right away so we know the cable is working just fine. What could be causing the Xbox controller to not work?

The AT&T LG G2 is rooted running 4.2.2 with stock ROM. The Keylayout file `vendor_045e_product.028e.kl` used for the Xbox 360 wired controller was already on the phone. Running the app titled "USB Device Info" with the Xbox 360 wired controller plugged in shows the controllers info in both the Android and Linux tabs. The device seems to recognize everything it's supposed to but won't work with any games or emulators. It wont even allow the controller to navigate the home screen.

# Answer
> 1 votes
While I do not have the final solution - I was able to make some progress in figuring out why the G2 fails to work with the 360 controller.

I've been doing diagnostics and noticed that the LG G2 USB connection manager is emulating a USB2.0 and USB3.0 device hub - which shows up when an OTG cable is connected to the phone - and while it identifies the 360 controller, its non-standard integration is likely causing the device to not be recognized by applications.

Using USB/BT Joystick Center from the play store, I was able to refuse permission to access the USB Hub devices, but permit the app to talk to the Xbox controller. (When it scans for devices, it will display "FOUND: *Device Name*" then prompt for permission. When it displays "FOUND: Xbox 360 Controller" approve access. Deny all other prompts, or else the software cannot communicate with the controller).

Immediately after doing the above, the controller's LEDs stopped flashing - and locked into 'Player 1' configuration. Then the software loaded a default 360 profile, and clicking on driver let me see the raw inputs from the controller. It works!

It seems to me that the device is perfectly compatible, but the LG OTG input manager is doing something funky with the input - and needs another piece of software to channel the inputs from the USB device to the system. If there were a way to get the LG software to identify it as a keyboard or gamepad, that would be ideal.

I'll keep working at it for now.

# Question
Title: Help Uninstalling Stubborn Application
I have the original Motorola Droid. I recently installed Lotus Notes Traveler on it (we use Lotus Notes at work). The application is giving some issues, so I was going to uninstall it and re-install it. Unfortunately, when I try to do that I get a message the message "Uninstall Not Succesful". Is there any way to uninstall an app that does not want to uninstall through "Manage Applications"?

# Answer
Apparently the Lotus Notes Traveler app makes itself the Device Administrator on the phone. You need to disable this before uninstalling it. The following quote is from Lotus FAQ:

> You should uninstall Lotus Notes Traveler by launching the Lotus® mobile installer application, then selecting the Lotus Notes Traveler application and choosing uninstall.
>
> If you choose to uninstall manually and your device is running Android 2.2 or above, you must first disable the device administrator. To do so, select Menu \> Settings \> Location & Security \> Select device Administrators. After you have disabled the Lotus Notes Traveler device administrator, you can use the operating system to remove Lotus Notes Traveler, by navigating to Menu \> Settings \> Applications \> Manage Applications.

Title: No external storage available - Storage gone
While I organizing files on my Galaxy Nexus via PC (USB), Gallery app kept saying `No external storage available` Then I restarted the device, and whole storage was gone..

What could possible cause this? And how can i prevent this happening in the future?

Using stock 4.0.4 (IMM76I)

# Answer
It looks like the phone can no longer connect to the SD card. Since this survives a reboot, it's most likely a hardware failure.

If your phone is rooted, `adb shell su dmesg` should contain messages that confirm this.

The “external storage” in a Galaxy Nexus is actually some non-removable flash storage. I don't think you can replace it (but I could be wrong).

It is possible that the filesystem is merely corrupted, in which case reformatting would work. You need to have a rooted device for that, and to install some additional tools from a Linux distribution.

# Question
Title: What is the dalvik speed patch?
Lately I've been hearing about a dalvik speed patch to supposedly increase the interpreting speed of apps through the dalvik JVM. The only mention on Google is Facebook's "hack" of the dalvik JVM to allow the Facebook app to install on legacy phones. I am sure this is not a dalvik speed patch.

Post where the patch is briefly talked about:

"New score...PA 3.99 RC2 + Franco r184 + dalvik speed patch.." https://plus.google.com/105415059081329756565/posts/4i8GDm47bnv

So what exactly is this dalvik speed patch?

# Answer

There's absolutely no magic here caused by a mysterious "Dalvik Speed Patch". The Author said that in the comments himself by stating:

```
Lol... I just mention dalvik speed patch, actually it's a kanged lib file...

```

So it's just a wording issue that you took as a rumour.

The higher Antutu benchmark scores are very propably caused by overcklocking using the Franco Kernel only.

Regarding your second thought about the FB hack: The FB hack has has nothing to do with this question. By the way, it's super ugly and something Facebook should be ashamed of: http://jaxenter.com/facebook-s-completely-insane-dalvik-hack-46376.html

# Question
Title: Does the new Nexus 7 (2013) have a GLONASS sensor?
According to a colleague who has the new Nexus 7 (2013) model already, there is a GLONASS sensor in addition to the GPS one in the device. Is this true? I was unable to find any reference to this alleged fact in the official documentation and via a casual web search.

Please state your sources in your answer(s).

# Answer
According to Ifixit's teardown, the Nexus 7 2013 uses the Qualcomm 8064 Snapdragon S4 Pro SoC. Qualcomm's specs show that SoC uses their IZat Gen8A GNSS chipset, which according to their overview does include GLONASS support, though this doesn't necessarily mean GLONASS support is actually active and available in software.

A simple means to test whether you've got GLONASS is to use GPS Status and Toolbox and see how many satellites it shows for you. If it shows more than 13 satellites, you're getting both GPS and GLONASS.
> 9 votes

# Answer
The definite answer is yes. I received my Nexus 7 (2013) a few weeks ago and today went outside to catch a few satellites. I'm using *GPS Status & Toolbox* whose user guide states:

> The sky grid (G) shows the GPS satellites above you as the receiver in the phone detects them. GPS satellites (with IDs 1-32) are represented by small circles **while GLONASS satellites (with IDs 65-92) are shown as rectangles**. The size of the symbol depends on the signal strength received from that satellite. The color shows what data is available for that satellite and how it is currently used by the phone.

Emphasis mine.

Here's the left side of the screen shot I took:

The Nexus 7 model would be the European one, if there are any differences.

The device would need to have two separate radios to be able to do this.

* Radio one for the wifi client
* Radio two for the wifi accesspoint

As phones cannot be upgraded with additional wifi cards, this is not possible.

(Technically it would be possible if the device had a USB-OTG capable USB port, but yours doesn't have this, and secondly the standard firmwares don't support such a setup either)

Title: Does Xperia S support HDR?
As the title says, does anyone know if Xperia S supports the HDR feature?

> HDR stands for High Dynamic Range. It usually refers to the method of capturing images having “greater dynamic range between the lightest and darkest areas of an image than current standard digital imaging methods or photographic methods” (Wikipedia).

# Answer

HDR has not to be enabled on the device. It is a software feature, combining multiple photos (see: Bracketing) into one. So you will need a camera app supporting this.

AFAIK the stock camera shipping with Android 4.2+ does so, plenty more are available on Google Play (not necessarily requiring Android 4.2+, most will run on your device). See e.g. Camera HDR Studio or HDR Camera for apps explicitly dedicated to this feature, or Camera FV-5 for an all-round-camera having this feature "amongst others". More to find out there.

Title: Internal Storage doesn't get mounted
I'm using PA3+ JB 4.1.2 on my HTC Vivid. Everything was working fine until Gmail app gets an update. After update, phone went into a bootloop. To recover, I went into TWRP and restored factory default, cleared cache and dalvik cache et cetra. Bootloop issue resolved but now when I'm trying to open Gallery/Camera app, it's giving me `No external Storage Available` error. In setting, when I try to mount internal SD card; nothing happens. I tried to mount card from TWRP but still, nothing is happening.

Should I flash ROM completely? Or is there any workaround to resolve this issue?

**EDIT**

I'm getting `Unable to mount /emmc (Invalid Argument)` error quite often in TWRP.

# Answer

Sounds like it might be your ROM. You could start by clearing the cache and dalvik. If it were me, I'd back up my sms and mms and do a full flash. I doubt a factory reset alone will help. I had an issue with permissions when my phone was connected to USB with certain ROMS, sometimes accessing with my PC, sometimes through recovery. I have to believe it's ROM related since the current version of PAC-man I'm using has been much more cooperative. I doubt it's driver related, but that'd be the safest starting point if you have sensitive data on your phone.

# Question
Title: New emails not showing up in Gmail app
I have 2 different Android devices: a Samsung Galaxy Reverb phone and a Samsung Galaxy Tab 2 tablet.

On both devices, I have just recently noticed that the official Gmail app is no longer showing new email messages in the list. When new emails come in, I get Android notifications. If I select the email in the notification bar, then it brings up the new email.

But if I just go to the Gmail app, then I don't see new emails in the list. I have to manually change from Priority Inbox to Normal Inbox (or vice versa) in order for the new emails to show up in my list.

Is this happening for anyone else? Is there a fix for it?

# Answer
Try opening the Gmail app, go to settings (click the three vertical dots in the top right), click on your email account and select "Default Inbox" as your Inbox type.

I expect this is happening because you've got "Priority Inbox" set as your default and this doesn't show all your messages.

Title: Rooting Android Galaxy S2 - Connection Error
I am trying to root my Galaxy S2.

So I followed instructions online, I booted in debug mode, connected the USB cable then pressed the up powerbutton to start the mode, I then opened up Odin v3 3.04 and it showed up with a device connected. I selected the correct .tar file under PDA and clicked start. It says "setup connection" and freezes at that.

I tried redoing it because it wasn't working. Eventually I decided to see if it was just the program. I opened Samsung Kies and it couldn't connect. It tried connecting for a long time and eventually just gave up.

The weird this is that when I plugin the USB cable my computer actually recognizes it as a Samsung Device because the first time I plugged it in it installed drivers automatically using Kies.

I tried using different USB ports, tried using a different cable and I tried charging it.

I couldn't tell if it was fully charged but it charged for 8 hours so I'm sure it was charged fully. Still didn't work.

After researching for 2 days and trying endlessly, I decided to see what you guys think.

So let me know if you have ideas! :)

I tried uninstalling and reinstalling kies, now it is connecting with Odin but it wont connect with kies at all. But its now showing this error.

# Question
Title: Do I have a virus on my phone? A message from an Android app says so
I have just received a message from an Android app on my phone saying my phone has been infected with a virus and to click a link to fix the problem.

I'm not sure I trust this, is it possible to have a virus on Android?

# Answer
It is possible to have malware on Android, although these usually 'infect' a device through downloading and installing apps from un-reputable and/or warez sites. When installing any app you should review the permissions and not blindly download/install an app simply because it looks ok.

It is possible that the message you received is from a malicious app or an app trying to get you to install malware. You can install a security app such as Lookout or Avast and they will scan your device for issues/malware. Be aware that anti-malware apps such as these can report false positives, and they may not detect all issues so you need to use common sense and ensure you only install apps you trust.

# Answer
In addition to the possibility that bmdixon raised of malware, I'd like to add that it's entirely possible that it's not even necessarily malware, but rather instead social engineering type adware trying to get you to install malware or buy something useless. You often see those types of pop up messages on websites for Windows users, and this sounds very similar to me. Without more info, like which app popped up this message or a screenshot, this would be my guess as to what's happening on your phone.

Many of these types of adware can be blocked using system-level adblockers such as AdAway, which can be installed from repositories such as F-Droid if you have root. (such blockers are no longer available on Google Play as they undermine Google's primary business model) Or of course by not installing apps that rely on ad revenue in begin with :)

You likely have an instance of "rogue security software". Despite the name, it only pretends to be security software. From Wikipedia:

> Rogue security software is a FraudTool (a form of Internet fraud using computer malware) that deceives or misleads users into paying money for fake or simulated removal of malware (so is a form of ransomware)—or it claims to get rid of malware, but instead introduces malware to the computer.

Unless this message is coming from a tool that you know and trust to reliably treat malware infections, do not follow the link, and remove the software, if you can. If the software came from the Google Play store, report it for investigation.

# Answer
Android apps that pose as legitimate apps and warn you of such malware and provide a link to help you clear the virus ARE THE ONES THAT ACTUALLY INSTALL MALWARE.

I recommend that you do the following:

1. **uninstall** the app that is providing the link.(unless it is a very very useful app which I doubt it is)
2. If you can't decide if it is a legitimate app, search in Google play and search in Google for reviews.
3. **Never side-load apps from untrusted sources, unless you know what you are installing.**(I am not against side loading, actually I do it a lot myself)

# Question
Title: How can I get the history list of times I started using an application?
I want all the timestamps of every time that an app has started running.

I tried searching in the Play Store but I didn't find one. I downloaded an app called AppUsage which shows the Last Launched timestamp but I want all the timestamps

# Answer
> 1 votes
The Android system stores statistics on this, which on most devices can be accessed via a hidden menu:

1. Open your dialer
2. Type `*#*#4636#*#*`
3. A menu will open. The 3rd entry should read "Usage stats" (or something similar). Tap this.

You should see a list of your apps, which tells for each app how often it was started, and how long it ran. Using the drop-down box on top, the list can be sorted by usage time, usage count, or app name.

Remark: AFAIK this list will be reset when you restart your device.

---

**Edit:** In case your device provides no dialer (thanks @ce4 for pointing out my lapsus), it will require some searching to find the appropriate menu, but it's doable. Some launchers (e.g. Apex Launcher) provide the possibility to create shortcuts to "activities" (rawly: screens provided by apps). Long-tap a free space on your homescreen, then select "shortcuts", then "activities". Now scroll through the quite long list to find it. On my *LG Optimus 4X* the activity is called "Test" and has a "Gear" icon (same as the "Settings" app has in this menu), so that's the first place to look for: scroll to "Settings", open the drop-down, look for "Test".

There's LaunchStats which should work as is on versions up to (including) Android 4.0 Ice Cream Sandwich. This app scans the system logs for all app starts since the device was booted and extracts the data you want.

However starting with 4.1 Jelly Bean the necessary READ\_LOGS permission has been restricted to system apps due to security concerns. It is still possible, but you need to grant that manually via the developer console on your PC (adb is part of the Android SDK):

```
 adb shell pm grant de.goddchen.android.launchstats android.permission.READ_LOGS

```

See more background on how to grant this permission here. You also need to enable adb debugging on your phone in the developer options.

I am having a Belkin 4 port USB hub and an Android 4.1 tablet Model M736 made by Kocaso. I am trying to connect USB keyboard and a USB WiFi dongle to the hub and not able to see either of the devicces. Tried only the keyboard connected to the hub yet not able to recognize that a keyboard exists. But individually the devices work when connected directly to tablet. Could it be that the USB hub isnot able to support enough power when connected to the tablet.

Any suggestions

Connect a self powered USB hub and try again.

USB-OTG ports often provide little power that's suitable for one device only, but may already fail for power hungry devices like very fast USB thumb drives, wifi dongles or 2.5in USB hard disk enclosures. Your setup very probably draws too much.

You can use any 3rd party USB power bank if you need it on-the-go. Your hub may have a power input connector already. Finding the right cable might be an issue though. Here's some related info, someone asked this for the SGS i9000 which doesn't provide power at all: USB host mode not working on Samsung Galaxy S using CyanogenMod

# Question
Title: Wifi battery saving tips or automation
A person that is not expert in computers & technology (including smartphones) bought a Galaxy Mini S3 and asked me some help. He is very old of age.

The problem with this phone is that Wifi drains away lots of power. The battery barely survives half a day. Disabling wifi multiplies the battery duration. It is normal that disabling wifi helps battery survive, but the difference with this phone is dramatic (my S3 "large" lasts more).

The basic idea is to disable wifi when not needed, something that I do every time I go out of home playing Ingress. But that user is not an expert and hardly can be taught how and when to enable/disable wifi. He needs Viber, which he learned how to use, when home. When out of home, no wifi is needed.

I would like to ask if there is any application that can be used to turn wifi on and off depending on the location of the device, possibly avoiding draining battery because of the GPS. I was thinking about coarse location based on cell tower.

I was also thinking about the old Microsoft On.X.

Or, can any other trick be used to make battery last a little longer with wifi on?

An important thing I found: I let the user use the phone mainly in standby for an almost full discharge. Battery meter said that `Android OS` consumed 62% of battery. Wifi was only consuming 6%.

This morning the phone was fully charged. After about 4 hours the battery level, with wifi manually turned off, was of 98%.

Tasker is an app that can be used to automate changing settings on your device, based on various events like when you leave range of a wifi AP, or when you enter a geographic area.

You can have a look through the Tasker tag here for some idea of the jobs it can be used for, and how to configure it.

Thanking GAThrawn and Izzy for the feedback I also want to post two scripts in `On.X`'s Javascript-like syntax

1st script: enable wifi only when home (inspired by a Microsoft script)

```
// Initializing variables
var action = "enter" /* arrive */;
var region = { name : "Home",latitude : XXXX,longitude : XXXX,location : XXXXX } ;
var action2 = "exit" /* leave */;
// End of variables initializing
//Create New region is necescary to set the radius
var myLocation = device.regions.createRegion({
   name: region.name,
   latitude: region.latitude,
   longitude: region.longitude,
   radius: 100
});

myLocation.on(action, function(){
    device.network.wifiEnabled = true;
});

myLocation.on(action2, function(){
    device.network.wifiEnabled = false;
});
device.regions.startMonitoring(myLocation);

```

2nd script, also useful, toggles wifi on charge (supposing the phone is charged at home)

```
var batteryChargingEvent = "startedCharging";
var batteryChargedEvent = "stoppedCharging";

device.battery.on(batteryChargingEvent, function (signal)
 {
     device.network.wifiEnabled = true;
 });

 device.battery.on(batteryChargedEvent, function (signal)
 {
     device.network.wifiEnabled = false;
 });

```

Using both shouldn't be a problem unless one uses a portable charger

You could also look into an extended life battery (usually larger with a custom backplate.) Not really solving the problem, but definitely an option, and maybe simpler.

# Question
Title: S3 battery not work after water damage
I dropped my S3 in water and the stock battery stopped working. I didn't know how to fix it (I tried drying it with a hair dryer but it did not work) so after comparing prices and discounts I bought a new replacement battery from MPJ and have used it for a month already.

It appears to work just as well as my stock battery. I don't know it's actual longevity but it works OK so far. Since I ordered from an official website, hopefully it's not a fake one...

I still want to fix the stock battery though, can anyone help me?

# Answer
Basically, you can't. The charge/protection circuitry in the battery probably got damaged by the water, and you're done now.

Count yourself lucky that it was only a new battery that you needed and be happy.

Title: Samsung Galaxy: Unlock gone haywire
I applied the procedure to unlock a Samsung Galaxy S3 on a Samsung Galaxy Express I437. It went through smoothly, and but the phone was not unlocked. Instead, it gives me the error message "Phone not allowed MM#6" after I inserted a foreign SIM card. The procedure is reproduced below:

\[1\] UMTS \[1\] Debug Screen \[8\] Phone Control \[6\] Network Lock Options \[3\]Perso SHA256 OFF (after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in \[6\] Network Lock then choose \[4\] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone

Since this didn't work, I tried reverting NW LOCK back to the old setting. Unfortunately, it doesn't work. The unlock screen doesn't come up anymore. And I have no other way to enter an unlock code. Does anyone have any idea how to resolve this issue?

Million thanks!

# Question
Title: Copy data from phone to wifi network
USB port on my phone broke (can't transfer data). My phone uses built-in memory, no memory card.

It works, I connect to wifi, etc. Is there any software or easy way to copy all my files from phone to network? Mostly I need to get pictures and videos out. Using email will be tooo slow.

# Answer
You can use an app such as WiFi Tiles transfer. All you have to do is to download the app and clicking the `start` button. Then you can go to the server page you're given (on the app screen) and you can access all the files and folders of your phone memory.
> 0 votes

# Answer
Connect to the WiFi network. Install Dropbox/Google drive or any other similar service on your computer. Install the app for the same service on your phone. And then go into your favorite photo browser/gallery and send the files over to the service and then you will have them automatically on your computer(if you have installed the applications).

This also gives you a backup of the photos and videos.

**Simple steps one by one, with my recommended service:**

1. Connect to WiFi with your cellphone
2. If you dont have a Google account, make one here: Google Signup. Most likely you have a google account, when you have an Android phone. Otherwise, you can not download apps through the Google Play.
3. Install "Google Drive" on your computer. You can download it from the google drive download page.
4. Install "Google Drive" on your phone. Download it from the Google Play store.
5. Go into your favorite photo browser or gallery app on your phone. You can then select all files or only the ones you wanna transfer, and choose the "share"() button and choose "Google Drive". It will then use some time depending on the internet connection you have.
6. You can then go on your computer and find the files inside the "Google Drive" folder.

Your files is now safely saved/backed up on three devices. Your computer, phone and "Google Drive".

I hope this solution works for you.

You can also make a permanent solution by downloading and using FolderSync wich will automatically upload photos to Google Drive when you take photos or videos.

# Question
Title: How do I get this iTunes song on an Android device?
I want to buy this song, but it appears it's only offered on iTunes. I have no idea if it's DRM protected or not, I just want it on my Moto X.

* What are the most direct and straigtforward steps to determine *if* I can put this song on my device, and how I can do it?

I would like to purchase the song directly from my phone, but I have both a PC and a Mac

# Answer
In recent years, Apple has sold songs on iTunes without DRM. You can convert them to other formats pretty easily, then just drop it onto your Moto X using a USB cable (Or even just email it to yourself, then download it using your email app on the phone).

Music stored on the phone should automatically be added to your "On Device" library in the Play Music app. I would recommend making sure you save it somewhere standard like `/sdcard/Music/` for your convenience.
> 1 votes

# Answer
I don't like iTunes much, but I keep it around because I still have an iPod floating about. I have the Google Play Music uploader synced to iTunes. So, were I to buy a DRM-free song in iTunes (and it, of course, is locally downloaded) it will automatically be converted (if necessary) and added to my Google Play Music library and I can pin it to my device for offline enjoyment.

The only time this doesn't work flawlessly is when the source song has DRM on it. If I recall, though, everything coming out of iTunes these days lacks DRM. (At least, music is that way.)

# Question
Title: How do I install, update, and remove apps for multiple devices in the Google Play online store?
I've got several Android devices. I like to use the online Play store to manage installs because it's much faster than doing so through each device. However, I do not see a way to determine which apps are installed on which device without clicking through the following links, **once per app**:

> Apps → My Apps → \[specific app\] → Installed → Choose a Device

How do I quickly do the following, without going through the process above?

1. Review per device installations.
2. Select apps for installation, update, or removal, per device.

# Answer
> 5 votes
Unfortunately Google play Web app doesn't allow you to the following things:

* Update your current apps (It can only be done from your devices)
* See a list of apps install in a specific devices (It only tallies all of the apps you ever downloaded into one list)
* Remove any devices which were previously added to your Google account

Hopefully we can raise awareness through this question so that Google finds that enough people will like a lot more functionality from the web app. It is sometimes very functional specially if you work in a computer all day.

Title: How can I enable calling over Wifi for a T-Mobile based Moto X?
T-Mobile allows for unlimited calling when I'm tethered over Wifi, on my old Blackberry Bold this was called "UMT" or something like that (it would appear in the status bar).

Since I still have poor reception I rely on wifi calling to get signal in the basement of my house.

How can I enable this T-Mobile specific (and no it's not Skype) wifi calling to work over a standard Wifi connection?

# Answer
> 1 votes
The Moto X does not support T-Mobile's WiFi calling. Customer support reps have stated that this is because it is not a carrier branded device, meaning they have not modified the system ROM to add this feature:

> The Moto X does work on our network but because it is not a T-Mobile branded device we do not support WiFi Calling on it.

You'll either need to set up some other VoIP service or get a different phone that supports this.

title: Can't log in to Hangouts

# Question
Title: Can't log in to Hangouts
I just uninstalled and reinstalled Hangouts to get the updated version. (Even though the market showed the new version, it didn't have "Update" yet).

Now, I cannot log in to Hangouts... it keeps asking me to add a Google account. I've tried rebooting the phone, but no joy.

Gmail and other google apps still work fine, it's just Hangouts. I've tried adding my account, and it tells me that it already exists on the device (which is true).

# Answer
So this turned out to be a pretty easy fix, once it dawned on me what it was. I just recently installed the Xposed framework, and the XPrivacy module. When I uninstalled the old Hangouts, it must have deleted all the old permission settings in XPrivacy, and then when I reinstalled it, it defaulted to maximum restriction.

With access to the phone accounts restricted, Hangouts was not able to see my google accounts.

The fix was as simple as fixing the permission settings for Hangouts in the XPrivacy module.

# Question
Title: Does official Gmail app use a secure connection?
As simple as that, when I'm using the official Gmail app to access my email account, does it use a secure connection?

# Answer
> 9 votes
One should be careful to differentiate between the gmail app, and the default mail client.

**Gmail App**

The Gmail app is the pre-installed app created by Google that can only be used with Gmail. The answer to whether or not the Gmail app is secure requires some understanding of Android app security. This passage from the dev guide explains how developers may connect to an SSL Socket to securely send TCP/IP communications.

Since the Gmail app uses SSL Sockets when sending and receiving mail, all communications are secure \[citation needed\].

**Mail Client**

Unlike the Gmail app, the default mail client can be used with any email account, including Gmail. When using this client to send and receive Gmail, an SSL connection must be used. The app is therefore also secure. Google explains how to do this in their help pages.

# Answer
> 10 votes
According to this Google page the Android Gmail app uses an SSL connection in both directions.

# Answer
> 0 votes
I don't believe that it does use SSL, but my evidence is circumstantial/anecdotal.

Yesterday I connected to a public WiFi from my Nexus 7. The native Gmail client successfully retrieved mail (on two accounts), but when I went to open a Google website through Chrome, I got the "The site's security certificate is not trusted!" message. Chrome for Android wouldn't give me any more details (what the specific problem was), but it seems to me that if the SSL connection wasn't good enough for Chrome, it shouldn't have been good enough for the Gmail app either. Ergo, either Gmail doesn't use SSL, or it doesn't use it securely (which amounts to the same thing).

I'd welcome another explanation, but based on the above, I changed the passwords on both those accounts immediately after.

# Question
Title: How can I uninstall the Cyanogen Mod 7 for my Htc Incredible 2?
I bought an HTC Incredible 2 on Amazon and found out that it is modded with Cyanogenmod 7. I didn't install it myself. Is it possible to uninstall CM7, or is it just built in? It doesnt even look like how an HTC Incredible should look or act.

Im wondering if I got another version of the HTC Incredible 2, but I didnt think there is another version.

# Answer
It looks like you purchased a used phone on Amazon. CyanogenMod is an extremely popular Android ROM that tries to give you something close to a "Pure" Android experience by removing customizations that HTC and other manufacturers put on the phone. **Personally, I would recommend you keep CyanogenMod.**

But if you just don't like CM, there is a tutorial on XDA Developers that will guide you through the process of restoring the phone back to its original state. **Restoring the default software looks pretty difficult** for the Incredible 2.

You will need to get...

1. The HTC ADB Driver
2. The Android Software Development Kit
3. The SuperOneClick tool
4. Apparently, two versions (Links: 2.2 and 2.3) of the Android software for your phone.

The steps to follow are listed in that post, but they **may be outdated**. If they're wrong, or if you mess up somehow, **your phone could very well get broken permanently**.

All in all, you're free to try to remove CM from your phone. However, you may want to consider keeping it for two reasons:

1. CyanogenMod is considered by many to be superior to HTC Sense (Especially older versions like on the Incredible II).
2. Trying to remove it could lead to very bad things, like a permanently broken phone.

*Please note that all the links are provided by third parties, not by HTC. I got the links from the XDA Post that I linked to in the second paragraph*

# Question
Title: What is the range of my wifi tethering network?
My Samsung Galaxy Y (GT-S5360L) can run a wifi tethering network at 32 dBm, according to iwconfig. This is almost 2 watts. Is this reading accurate, (my battery is 1200mAh, 5v, or 6 watt hours, so it seems sort of fishy, but it does drain my battery really fast when I run it), and if it is, (assuming nothing blocking the signal) what is the range of the network in meters?

# Answer
32 dBm equates to 1584.89mW according to this calculator: http://www.radiolabs.com/stations/wifi\_calc.html Assuming a 12 DBi Antenna Gain from the comments above, that gives us 44 dB of antenna power. The signal loss for 2400 MHz/Km is 100.03dB, citing the same site.

At the assumed 44dB of power, we'll round and say .044Km which is ~144 feet. Since throughput is inversely related, You're going to have a pretty poor download speed at 144 feet, barring there's nothing between the phone and the computer, on a clear day.

This is half guesswork, but hopefully it helps.

Title: Use Quick Responses with Google Voice
One of the most useful features introduced in Ice Cream Sandwich is "Quick Responses": the ability to send a default SMS message to the caller. "Can't talk now. Will call you back." etc.

However, I'm 100% Google Voice. I only ever give out my GV number, and I don't want to broadcast my actual cell phone number by using a Quick Response.

Is there a way to use them with Google Voice?

# Answer

This is apparently not currently possible.

I'm not the only person with this desire. There's an open issue at Google (Issue 23176).

In one of my searches, I found someone who says they looked into the code for the Phone app, and found that it's calling the Messaging app directly without allowing the Messaging Intent, which is what would prompt me to choose the Messaging app versus Google Voice to send the message.

The app suggested by dymutaos looked somewhat promising, but I am concerned about its security.

So, unfortunately, this very useful feature is currently useless to me. I hope they fix it in the not-too-distant future.

# Answer

You could try this app (they have a limited free version). It is supposed to integrate Google Voice into the native messenger, so it may also work with the Quick Responses, depending on how Android actually implements them.

# Answer

Once you have Google Voice setup, you could try simply going to Settings\>Apps\>All Apps\> MMS.apk - & Clear Defaults.

Then, when you select a quick response, it should prompt you to use GVoice, instead.

# Answer
> 0 votes
Not yet, apparently there are hooks in the code called intents that are responsible for asking which app you would like certain tasks to be performed by. The quick responses did not have intents. They are there as of Android 4.3, but Google Voice has yet to update with a register for that hook. https://code.google.com/p/android/issues/detail?id=56090

Google voice has the following option which sounds like it could do what you want, but only when texting to another GV number. This is according to the "learn more" text on the site; I haven't experimented to find its real capabilities:

```
- Caller ID (outgoing)   When I text a Google Voice number from one of my
  forwarding phones:
     - Don't change anything
     - Display my Google Voice number

Title: How to Disable Auto Silence
My Motorola Electrify M keeps auto-silencing the ringer. How do I disable auto-silece? My phone is running Android version 4.1.2.

It seems to go on silent when I have meetings scheduled. It wouldn't be so bad, except that it never re-activates the ringer, so I keep missing calls! Any thoughts on how to disable the auto-ring silencer would be great. If it makes a difference, I'm also using the calendar app aCalendar.

The Motorola Electrify M comes with a set of functions called Smart Actions, which can be deployed. A sample from their User Guide is the silencing of the ringer when inside meetings. See the User Guide here to find help in refining the criteria triggers, so that the ringer is restored. Look for \Control and Customize\Smart Actions\Help.
Like most trigger-based actions, each comes with some downside, so either some refinement, or complete disabling will solve your difficulty.

# Question
Title: Why does charging leads to battery losing charge at times
I have a LG Optimus S Android on Gingerbread (The one on the cheaper side with least specs for an Android).

I have found that when I use the USB charger connected to my computer, at times instead of charging my phone, the battery gets drained. (Also I perceive that the battery gets drained faster than normal phone usage at such times)

While I have a fix which is to restart my Android phone. Could someone explain why such thing happens?

# Answer
Now your typical wall charger on a smart phone provides 1A of charging current. The USB 2.0 on a computer will only supply a max of 500mA, that is half as much. So if your screen is on and you are using the phone then it is drawing more power than it is taking in since the screen is the largest drain on the battery, therefore the battery will drain while charging on a USB connected to the computer.

You can connect your device to the internet (using Wifi) and continue to use it just as you would with a plan.

So you can download as many apps as you want to your device using Wifi.

You don't need to be connected using the cellular network to access the Play Store (but do need the internet).

There are certain alternative App stores that are trustworthy, but be wary of downloading APKs directly off the internet. There is no guarantee these are safe - generally, use the same caution you would use downloading software to your computer on your phone. Only install from reputable sources.

You can actually pull an APK (Android App Package) off one device, and put it on another (using your Linux box), but this is not a task for a newb (you would need to install and use the developer tools)

# Question
Title: What podcast apps include variable speed playback?
I know about Astro Player. Any other apps that feature podcast managment and variable speed playback?

# Answer
If you'll pardon the "non-answer"...

I wrote Taffy to act as a proxy between your Android device and the podcast provider. It speeds up the podcast before your podcatcher downloads it. There are several undesirable aspects to this approach (hosting not the least among them, nor inability to *change* playback speed during playback), but I use it every day to listen to several podcasts on my Droid at faster speeds.

Here's to it becoming obselete soon.

My Droid uses BeyondPod, pointed to Taffy podcast feeds, to automatically download all of my podcasts straight to my handset during pre-dawn hours. I wake every morning (and have for months -- Taffy's a pain to setup, but it's pretty smooth sailing from there) to no-hassle, "sped-up" podcasts ready for my commute.

Today, Presto entered open beta. Presto provides a background Service which allows other applications to play MP3 and Ogg Vorbis files on your Android device at faster or slower speeds and/or faster or slower pitches, so that any application can have variable speed playback, as long as the end user has Presto installed. Developers must modify their app for Presto to be used while playing audio, and I've released open source code to make that almost a drop-in replacement for the Android MediaPlayer.

Unless Samsung are complete muppets, even they don't know your password: all they know is a special *hashed* form of the password, which is an irreversible function a bit like encrypting it. When you type in your password, they *hash* what you type in in the same way, and then compare the two hashed passwords. This way, they can check your password without knowing what it is.

For this reason, there shouldn't be any way to find out what your password is without first changing it. If that turns out not to be true, it would be a very embarrassing security problem for Samsung.

If you want to find a lost or stolen phone, there are other options that don't involve your Samsung account. See the answers to My phone was just stolen an hour or so ago. Are there any options for tracking? for some alternatives that you can install remotely via Google Play.

Though they are not necessarily linked, to find RAM usage:

```
Menu/App Drawer > Settings > Apps > Running

```

Some apps listed in this section might not be important but drain lot of battery over time.
Try to uninstall suspicious apps one at a time and figure out the effect on battery life. Find alternatives to apps which are eating up lot of resources, if possible.

You could also use an app (such as AVG Anti-Virus) to stay safe from malicious apps and have a control on various factors which could contribute to battery drain, such as GPS, Wi-Fi, screen brightness etc...

# Question
Title: What happens when using a cellphone when charging?
What happens when a phone is being used with the charger connected?

Will it take power from charger and save the battery usage?

OR

At one end, the charger keeps charging the battery and at the other end, phone discharges the battery simultaneously?

(I am using Sony Xperia SP with Android 4.2.1)

# Answer
As using the device also uses some power, the device cannot "charge with the normal speed" at the same time. It will however primarily use the external power source for its consumption. Depending on whether you "consume" more power than the source can feed, either it compensates by taking whatever is needed additionally *from* the battery, or feeds whatever is left *to* it.

A side effect described in the other answers already is true, however: the device will get "warmer" this way. I already described that in another answer:

> Recommendation for cold days to get warm fingers: Take your device with both hands, plug in the charger. Now stream a HD video from youtube via 3G, play it fullsize, and in the background do some video recording which in parallel gets uploaded via 3G. **CAREFUL !!!** Wear gloves... #-)

# Answer
The answer is :

* Your phone is charged no matter what.
* But at a slower rate than normal.
* Making it warmer than normal.

# Answer
Your phone charges with the normal speed or rate. And it makes your battery heat up more and nothing else.

Title: How to use an USB 3G modem data connection with an Android phone (Galaxy Nexus)?
I own a Galaxy Nexus phone and i'd like to know if there is a way i can use an USB dongle to provide it with an Internet connection.

I imagine I will need some kind of adapter (and some Google searches suggested an USB OTG cable).

I'd like to know if the stock OS supports this (i have Android 4.2.2 currently) and if I'd need root or a customer kernel. Also, if it is possible, could you please provide a guide on how to do this?

# Answer
**Officially**: This is not possible, except for certain (older?) Archos tablets.

**Inofficially**: There's the Autopatcher project . It includes patches to enable 3G modems on wifi-only tablets (it may be possible to use those on phones too, but YMMV).

Autopatcher supports these Android firmware flavours:

* some 3rd party firmwares (CyanogenMod, AOKP, ParanoidAndroid, PACman)
* AOSP 2.3- \> 4.3 (e.g., Google's Nexus line)
* ...and others

Not supported are original HTC, Samsung and other branded firmwares.
