Title: I have over 2GB of internal memory and can't install or update some apps
I tried to search for some answer but couldn't find anything.

I'm using cyanogenmod-11 on a Samsung Galaxy S4 Mini.

I am pretty sure I have enough space on the internal memory, but I still receive the insufficient space message when trying to update and/or install some apps, but not all of them.

What could be the problem?

# Answer
Try the `fix permissions` entry in your custom recovery menu. In most cases this fixes the problem.

I ended up reinstalling the entire opperating system and that solved the problem.

Title: Nexus 10 stuck in bootloop after Lollipop flash no ADB and no Fastboot
So .... I flashed the *mantaray-lrx21p* image from Nexus Factory Images on my Nexus 10 (16GB Wifi) and it's stuck in a bootloop.

No problem, I thought, I can get into fastboot and fix it, right? Maybe do a wipe and try again? Yeah, not so fast. I get the bootloader screen, but the only option is 'Start' which just boots into the system that bootloops.

That's OK, I'll just use fastboot to wipe it. Nope. Fastboot doesn't detect a device.

I've tried both ADB and fastboot on Mac & Linux. Same issue.

Ideas?

I was trying to enter the bootloader with the *USB cable plugged in*. Once I unplugged the USB cable and held `power + Vol Up + Vol Down` it booted into bootloader and I was able to get fastboot connected.

I'm having this exact same issue. I'm going to try flashing 4.4 again and see if I can at least get it up and running again.

Edit: I was able to get it booting my locking the bootloader. (run fastboot oem lock from bootloader)

# Answer

Had exactly the same on my Nexus 7 2012 just now.

Flashed the factory image, device remained stuck at the boot logo. went to bootloader and did "fastboot erase cache" along with "fastboot erase userdata". Still the same never ending boot logo.

Put the device back into bootloader mode again, ran "fastboot oem lock", restarted and the device quickly started loading the OS as normal. Currently staring at "Android is Upgrading...." .

locking the bootloader is a good way to go. you can then backup any data you want off the device if you didnt originally erase it all before running "fastboot oem unlock".

I'm seeing the same issue. Booted into download mode, and neither fasboot nor ADB see the device (MacOS 10.9). They are working for me on my Nexus 5, so it's not an ADB/fastboot driver issue or anything.

title: What processor images to install

# Question
Title: What processor images to install
After downloading and installing Android Dev Studio and Android SDK, a question arises:

Which System Images should one install?

For example, one would like to write a simple android game, that should be run mostly on mobile devices (e.g. pads and smartphones). I guess in this case most many Images are not needed.

Is there a good way or routine on how to choose which System Image to install? So the system is not over-flooded with unused tools.

# Answer
The major problem with running Android virtual devices (AVDs) is that they are usually very slow, even on fast hardware. For this reason, consider using the HAXM accelerator which will work with a x86 image

https://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager

You can still keep an ARM-based emulator for when you want to make sure it works, but while developing it would probably be easier to use the x86 Android image, as most of the functionality would be the same as the ARM version.

# Question
Title: My photos are gone
I was sick of photos from web pages I visit being stored on my phone, so after researching I installed a `.nomedia` file.

However, since doing this all my photos from my gallery are no longer there: I can see them in media explorer, but there is nothing in the gallery! Can anyone help? Any photos I take on my camera now are happily appearing in the gallery, just all my old ones aren't there.

My device is a *HTC One M8*.

# Answer
> 1 votes
To see your pictures again in the gallery, just remove the .nomedia file, it's hiding the pictures in the folder from the media scan.

You need to trigger a rescan to be executed by the media-scanner (e.g. by performing a reboot) for your photos to show up. Only thing I wonder: new photos are shown, just old ones are gone – that sounds like a different issue, unless the new ones use a different folder.

Sure, just repartition the card. Not that you'll lose any data on it, so take backups. Alternatively, if you don't need another kind of partition, you can just change the partition size IIRC. I recommend gparted for editing partitions.

# Question
Title: Google location history... wild anomaly
Was driving home today from a trip up north and decided to check my journey on Google's location history after I got back. Phone is a Nexus 5 running Android 5.0. The locations mostly correct apart from one obvious wild location - which is clearly impossible. Any ideas what could have happened?

# Answer
> 0 votes
I have also had this happen, though when tracking my location for an exercise app.

I assume that I connected to a WiFi network unknowingly and that network was routed through a proxy in that far-away location. Thus, Google thought that I was farther away. I started turning off my WiFi when using that exercise app to track my location.

The root of this is that Google uses a combination of GPS, wireless network, and WiFi information to determine your location. Of these three, the WiFi is most likely to yield an incorrect answer.

# Question
Title: No cellular network after OTA to lollipop (Nexus 4)
I have a Nexus 4 with Kitkat, working fine with t-mobile (USA). Yesterday, I did an OTA to Lollipop (LRX21T; baseband M9615A-CEFWMAZM-2.01701.04). But after that the cellular network only briefly works.

First problem, I encountered was the lack of data connection, but after I changed the APN setting, it worked...but only briefly. Every time I reboot the phone, it can make phone calls, and access the data network for a few minutes (or sometimes I have no access to begin with). But then the network indicator becomes either an 'empty triangle' or a 'full triangle with an exclamation point'. Then, I can't make phone calls or use the data afterwards.

Very strangely, I just found out that if I connect to wifi, I can make phone calls suddenly. If I turn off wifi, I can't make phone calls any more. What is going on?

Does anybody have the same problem? Does anybody a known workaround?

My current APN setting is:

```
T-Mobile GPRS

APN: fast.t-mobile.come
Proxy: not set
Port: not set
Username: not set
Password: not set
Server: not set
MMSC: http://mms.msg.eng.t-mobile.com/mms
MMS proxy: not set
MMS port: not set
MMC: 310
MNC: 260
Authentication type: not set
APN type: default,supl,mms,dun
APN protocol: IPv4
APN roaming protocol: IPv4
Bearer: unspecified
MVNO type: none
MVNO value: not set

```

Further testing using `*#*#4636#*#*`

* GSM service: in service
* GPRS service: disconnected
* Network type: UMTS
* Call redirect: false
* Call status: idle
* radio resets: 0
* data attempts : 0
* data successes: 0
* cellinfolistrate 2147483647
* IMS registration required is 'off'
* SMS over IMS is 'off'
* SMSC: \_______ \[update\]\[refresh\]
* Toggle DNS check: 0.0.0.0 not allowed

**EDIT**: During the moments when the network works, **GPRS service** is 'connected'.

**EDIT2**: If I force using 2G, it works fine. Just with unbearably slow speed.

# Answer
**UPDATE2: After a while, it seems like it cured itself. No more connectivity issues for a full 24 hrs. Perhaps it was a bad tower-radio(baseband) combination?**

**UPDATE: Actually, this didn't fix it completely. It behaves better, but it eventually goes into a state where the antenna says 3G, but there's no data nor phone connectivity. This happened 3 times.**

So, I think I fixed it by updating the APN address to `epc.tmobile.com`, switching to 2G only and rebooting, switching to 3G and rebooting.

# Question
Title: How can I get heads-up notifications for WhatsApp?
I really love the new heads-up notifications in Lollipop because they look much cleaner now, but it's really weird some apps use them or not.

I would really want them to work with WhatsApp, but I just don't find out how, or if it is possible.

Any suggestion?

# Answer
> 2 votes
**Update**: WhatsApp has implemented heads-up notification natively. However, users can still use the apps listed here to display heads-up notification for other apps. If the user is already using it, don't forget to disable WhatsApp's entry to prevent double heads-up notification.

---

At that time, it's impossible to do this directly from WhatsApp official app.

The heads-up notification is only shown when the notification is set to high-priority, max-priority, or full-screen notification by the developer. So, the "official" answer was to wait for them integrate the function.

However, there are 3rd-party apps that implement this feature for all apps:

1. Heads-up notifications
2. Heads Up! - notifications

You can control which apps are permitted to show the heads-up notification (I recommend you to do that before they flood the screen), and the customization is also pretty extensive.

title: Console logs disappear quickly

# Question
Title: Console logs disappear quickly
When I debug any app (native or hybrid), the console device logs they appear in the **logcat** but after **2+** min they automatically **cleared out** by Eclipse - though my device does not go in sleep mode.

It becomes difficult for me to check the logs and every time I have to first copy the logs to a text editor and then checking the logs.

Is there any settings required in eclipse or device?

# Answer
> 1 votes
The reason it's cleared because the log has exceeded the maximum limit of displayed messages on LogCat. You can change the limit by following the answer on Stack Overflow:

> The LogCat messages were simple getting cleared because the buffer had run out of space (receiving too many new messages), which is a simple setting change in Eclipse.

# Question
Title: Maximum number of alarm clocks
My HTC One (Android 4.3) told me that I can only have 10 alarm clocks at maximum and that I should delete one before adding a new one. Why, and is it possible to have more than ten?

# Answer
> 1 votes
Get Timely Alarm Clock. I've never tried more than 10 alarms but I guess it should be worth a try. It's free after all & extremely sexy.

Also you should try adding calender events instead of alarms and change the sound to something loud.

# Answer
> 1 votes
> Is it possible to have more than ten (alarms)?

Maybe not with HTC clock, but yes it is possible.

As mentioned by dotVezz in the comment, *"it's definitely not a constraint of the OS"*.

Android doesn't set any restrictions regarding how many alarms they can store/handle, even on per-app basis. A counter-example to OP's case: a stock clock on Nexus 4 (Android 5.0) can have 15+ alarms (I stopped adding after 15 alarms).

If you want to have more than 10 alarms, then you can just search it since *"there are a ton of alarm clock apps in the Play Store."* As already mentioned in other answer, Timely Alarm Clock supports more than 10 alarms.

> Why (is it impossible to have more than ten alarms with HTC clock)?

I can't really answer this without speculating as this is a decision made by HTC. Some possibilities that I could think off:

1. Less alarms are easier to manage
2. Less alarms won't hit the OS performance.

But for the technical part, Android is open-source and anyone can customize it as they like, including adding the alarm restriction on the clock app.

# Question
Title: Droid 4 no longer finding any GPS satellites
I have a Motorola Droid 4 with Verizon service. As of two days ago, it is apparently getting no GPS data from satellites. I thought it was a temporary glitch (cloudy sky, just turned the phone on, etc.) but none of my apps that use GPS are getting sufficiently accurate location data and it's clearly relying only on mobile network location.

A Google search for "GPS droid 4" hasn't been terribly helpful. Based on "How can I fix my Android's crappy GPS?" I checked that I've got GPS turned on (yes), am using AGPS (yes), having the mobile networks help with location as well (yes).

I downloaded GPS Status & Toolbox, and I get zero GPS reception even after leaving the phone sitting outside with a relatively clear sky for 30 minutes (far longer than it should ever take to get reasonable satellite fix with any GPS) -- no information at all for the lat/long. Resetting the AGPS and downloading new does not change anything.

I also tried GPS Test and can see zero satellites :\

Is this a problem that can be fixed (either by me or a professional) or am I looking for a new phone if I want to know where I am?

# Answer
> 0 votes
After the phone went through a factory reset, the GPS still wasn't working, which supports that the problem is hardware related.

The Droid 4 chip (indeed, all of the circuit board) isn't accessible without significant (read: warranty-breaking) disassembly, and I couldn't find any store that could/would repair.

# Question
Title: How to make Opera Mini the default browser?
I have tried many times to change my phone browser from the stock android to Opera mini... As you all know the stock browser is slow and unresponsive.

Before I get overloaded with comment: YES I HAVE CLEARED THE DEFAULT FOR THE STOCK BROWSER THEN TRIED CLICKING ON A LINK. And: NO it has not asked me what browser I want to use. IT just opens in stock.

I then tried installing Firefox. I did the whole process again. I went to open a link and hit "open in browser" and what do you know, it opened up in firefox! This was great to see.

Unfortunately I can't get this to work for opera. Although firefox mobile is great I have a preference towards opera. If anyone knows of a solution to this I would apreciate it greatly.

# Answer

It works with Opera Mobile, it should be the same for Opera Mini.

You can try this:

* go to the default Android browser apps settings and click on "Clear defaults"
* if settings in Opera Mini has a "Set as default" check box, select it
* open a link with a browser and select Opera Mini as default

If the above doesn't work:

* uninstall Androids default browser

# Answer

For Android users, it's simple. Go to:

*Settings › Applications › Manage Apps*, chose *All Apps*, scroll to the *Browser*, tap that entry, and hit the button to *Clear Default settings.*

Then as you use the message links, select Opera as the default browser.

One can't simply uninstall android stock browser. Because it should be installed as a system app. If you are rooted, then you can.

# Question
Title: Nexus 7 does not have Google Play app installed
A Nexus 7 tablet having android 4.4.2, does not have the default Google Play(neither older Android market) app installed.How is that possible?

I tried downloading \*.apk file from here and even here But did not work. When I tried executing the apk file, they hang and I get "ANR - application not responding" dialog.

For other \*.apk files for Google store app that i downloaded, it gave errors saying Error saying - "There was a problem parsing the package". It just did not work for many Google store apk's different versions i tried downloading and installing/running?

How can one install Google play store on this Nexus 7?

Would there be any correct/compatible \*.apk for Google play store available which would work?

Edit Note: I tried checking in settings and elsewhere to see if any default apps disabled setting is checked but could not find any such thing?

# Answer
I had a similar thing happen on a 3 year old phone I hadn't used in a long time. Android appears (at least in some cases) to be unable to upgrade from some old versions without installing the versions inbetween, which is of course impossible in most cases. While in my case the store appeared to be available, it didn't work at all. I ended up doing a complete factory reset to get up to date. I wouldn't expect this situation on a Nexus 7, but if you don't have a ton of data on it, you might try a factory reset.
> 0 votes

# Answer
You need to see if there are any of the other Google apps (GApps) installed. Most likely if the Play Store isn't installed then the rest of the GApps package is either. The Nexus 7 happens to be very easy to work with, so don't worry.

GApps Manager will be the tool that will be used. The link will describe the toolkit in detail as well as any fixes that have been made.

The Play Store - GApps Manager download.

The tool will be able to show android version, so you won't have to search. This will show all the packages available. The directions are easy to follow. Once complete you'll have the Play Store installed.

The only thing that might cause any hiccups is if you are on a custom ROM, which usually don't have GApps included because of legalities. Then you would find out what ROM and version, then go to the developers website and download the correct GApps from there. The custom ROMs will conflict with stock GApps.

# Question
Title: Does Nexus 6 sold by AT&T differ from one sold on Google Play in any way?
What are the differences between the Google Play Edition of the Nexus 6 and the AT&T version? Does it have any AT&T "bloatware"? Will its updates come from AT&T instead of Google? Is it locked to AT&T's network?

# Answer
Nexus 6 models sold via AT&T are reported to have these differences (source 1, source 2, source 3):

* It is SIM locked to AT&T
* There is an AT&T logo on the back of the phone
* The phone displays an AT&T branded boot animation/sound on startup
* It performs a check to ensure your current plan allows tethering before it will allow it to be activated
* Several AT&T ringtones have been added
* After the initial setup, if an AT&T SIM is inserted/activated, it will download and install several AT&T apps automatically. These can evidently be removed, without root.

It has been speculated that updates will still be received on-time because the AT&T extras are on a separate partition (mounted at `/oem`), but this has not been confirmed, to my knowledge. With root, you can remove the ringtones/boot animation from the `/oem` partition. You would need to obtain an unlock code in order to use it on a different network.

# Question
Title: Loud speaker on my HTC One turns on almost every time I answer an in coming call
My HTC One is about 18 months old. On almost every incoming call I receive, the loudspeaker turns on. Other than the fact you look like an idiot saying 'Hello' only to have your phone on the loudspeaker as if you don't know how to work the thing, it's actually pretty sore when you get a full blast 'HELLO' directly into your ear. I'm wondering if it's an Android issue or specifically an HTC One thing.

I honestly can't remember if it happened directly after an update, and I don't really have any odd apps, at least none I think would affect in-coming calls anyway.

This question is very similar to mine, but the apps which were un-installed to rectify the problem, are not and have never been on my device.

What is the possible reasons for this, and how to fix this?

# Answer
This is certainly not the default behavior of the M7 or M8; I've used both.

The way I see it, it's one of the following:

1. Some option in HTC's phone app or system settings has been enabled to invoke this behavior. I'd suggest reviewing the settings to confirm this isn't the case.
2. You may be experiencing some troubles with your touch screen. It's possible the touch digitizer is registering false positives, effectively tapping areas of the screen without you doing so.
You may want to check that touches are registering correctly by using an app similar to Yet Another MultiTouch Test and selecting the Paint Tester option. If touches are registered without actually touching the screen, this may explain the odd behavior.

I hope it's not the latter!

# Question
Title: Why Whatsapp images and videos are not showing in my gallery?
I have bought Moto G 2nd generation. I have Whatsapp installed in my mobile and it working very well. As you all know all Whatsapp images and videos will get displayed in gallery.

I decided to hide these images and videos. I have searched over net and found some useful links. Based on that, I have placed a `.nomedia` folder under `whatsapp/media` folder. After this, when I checked gallery, all images and videos from Whatsapp are gone. Eureka... Then I reverted the changes that I have made. That is I deleted the `.nomedia` file from `media` directory. But unfortunately, I couldn't find my Whatsapp images and videos in gallery.

So I cleared cache of Whatsapp via settings. Then I restarted my device. Still I didn't find my Whatsapp data in gallery. Now after getting some new images and videos through Whatsapp, I checked again. Now I can see those videos and images. But still the old images and videos are "hiding away" from gallery. Why?

I have checked Whatsapp folder. I can still see old images and videos in `whatsapp/media` folder and the new videos and images are added to the corresponding folders along with other images and folders.

How can I show all of my images and videos in gallery?

# Answer
> 1 votes
I believe the trick here is to somehow get the media scan to run again. I would normally expect a reboot to take care of this, but perhaps a more explicit instruction will work.

As per this answer, I'd suggest executing the following ADB command:

```
am broadcast -a android.intent.action.MEDIA_MOUNTED -d file:///mnt/sdcard

```

Also, be sure to check that `.nomedia` doesn't occur in any of the folders (or subfolders) of Whatsapp's media directories.

# Question
Title: Is there an Android app/widget to *temporarily* turn on mobile data?
Is anyone aware of an Android app or widget to temporarily turn on mobile data, then disable it again after a set period of time?

I have a bad habit of turning on my phone's data for a specific purpose, but then forgetting to turn it back off. As a result, non-critical apps (like a current-weather widget -- I don't really care if it updates current info only if I'm wifi-connected) continue to use data.

I'd like to be able to enable data and then disable it automatically 15 minutes or so later, when I invariably forget to turn it off myself.

Browsing Google Play turns up nothing likely, nor does a Google web search. The closest I could find was an app that turns mobile data on and off at specific times, which provides a proof of concept that this can be done, but still is not what I'm looking for.

# Answer

I got Tasker a few days ago, and it turns out this is pretty straightforward once I got past the learning curve and oriented to how it does things.

I set up a task with three subtasks (plus a couple test alerts to give me audible progress): (a) Mobile Data: Set On; (b) Wait 10 minutes; (c) Mobile Data: Set Off. Then I added a shortcut to the task.

Once I get a little bit better at Tasker, I'll probably try enhancing it to put up a warning dialog, allowing me to extend another 10 minutes or, if not responded to, continuing with the MD disable. But I've got what I need now anyway.

Make sure USB debugging is enabled from device, and do the following on your PC:

1. Update Android SDK (Google USB drivers updated)
2. From PC Control Panel, `System -> Device manager -> Nexus 4 -> Install driver`.
Set Android SDK as path to search, include subfolders checked.

After that, `adb devices` list will include Nexus 4.

USB debugging must be enabled.

You will know the device is connected, because it will show when you type `adb devices` into a command prompt.

Ensure you have the *correct* drivers installed, the ones from Google and/or LG, and then reboot your computer. Once that is done, reconnect the device. You may need to delete it from the device manager before it will install the adb driver correctlty.

Hold the power button until the phone turns off. Wait a few seconds. Then, turn it on, with the USB connected. Wait until the charging symbol appears. Then, turn on the phone.

Now, the Nexus 4 is showing in `My computer` again.

1. Plug in your phone
2. Go to Device Manager
3. Look for Acer Device
4. Expand that and you will see something like ACER Composite ADB Interface
5. Right click and delete that
6. Unplug and replug your phone and you should be able to get it.

Here's another tutorial if the method above doesn't work.

Title: Play Store Purchased Apps
I've kind of a dumb question. I've recently purchased an app from play store. I've not installed it yet, but I notice that there is a remove option for it. My question if I remove it, do I have to purchase it again or is it only removed from my apps list?

Once you purchase an app you don't have to purchase it again unless you switch Google accounts.

Title: USB debugging - No device found after chrome update
After attempting to begin remote(usb) debugging I finally had my phone recognised via the chrome/inspect page. At which point I was told I must update to chrome 39.0 Beta to access debugging.

After doing so the phone is no longer recognised. Xperia Z(C6603)- Android 4.4. - Chrome was on 38. Has been updated to 39.0.2171.62 (Official Build) beta-m

I'm new to all this so any help/suggestions would be amazing!

Title: Installing wifi certificate
I want to connect my Samsung Galaxy SIII to my University's wifi network. I have the certificate on my computer. I'm trying to install it.

It seems pretty absurd to me, but while Security didn't see the certificate, Docs to go actually installed it. However, this forced me to have a pin on the lock screen, or a password, which are both very uncomfortable for me, so this opens a new question.

# Question
Title: Can't mount /system as read/write, even though I'm rooted
My phone is rooted, and I tried to remount the system partition in a terminal emulator like so:

```
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
mount -o rw,remount /system

```

Both commands gave the output:

```
mount : read-only file system

```

Because of that I can't install Busybox, Xposed, etc. I'm using Android 4.4.2.

# Answer
Apparently under the new AOS, in non-root you may have certain things mounted in one way, but when doing `su` you get it mounted (or not at all) in a diffrent way. This is proably due to the new SELinux protection schemes. For example, to resolve unmonted SDCards you have to do `su -mm`, when using SuperSU. In addition the `toolbox` supported `mount` command is a bit crappy at times, so you're better using busybox. Make sure you use the latest *SuperSU* as it is the only reliable way to get proper root credential under the new SELinux systems. Then try each of the following:

```
su -cn u:object_r:kernel:s0 -c "busybox mount -o rw,remount /system"
su -cn u:object_r:init_shell:s0 -c "busybox mount -o rw,remount /system"
su 0 -c "busybox mount -o rw,remount /system"

In most android devices this insufficient storage issue is to do with Log files being dumped in the `/data/log` folder. The log files appear to be the logdump for the gsm radio, and can take up a lot of space over time (Gigabytes even).

Most phones without root have a workaround to delete the logs by dialing `*#9900#` from the phones dial pad. If your phone supports this then the moment you finish entering the 2nd hash, a menu will open up (point is: if it doesnt support nothing happens; pressing the call button wont help). In the menu that opens, select "delete dumpstate/logcat". That will free up all the space occupied by those logs.

Do let me know if any of you with a A116 is lucky to have this workaround. I have an A116 with the same problem, and am not able to find a solution.

# Answer
> 0 votes
The remaining storage is used for the Operating System(Android) itself. You can't free this space and put the operating system into the external card as it will not be possible to boot/switch on the phone. The Micromax A116 comes with a 4 GB internal storage in which 1 GB is partitioned for Android apps including the operating system. The remaining storage is for user use and you can store data by opening the File Manager. Source: I'm a Micromax A110 user and an app developer.

title: How to use NFC with RFID tags/chips

text:
# Question
Title: How to use NFC with RFID tags/chips
When I bought my Samsung Galaxy SIII, there was a big buzz about the new phones on the market supporting NFC (Near-Field Communications). However, given that Blutooth exchange of files and even the somewhat more powerful Wi-Fi Direct protocols were already available to allow files to be exchange, it seems to me that yet another technology (NFC), when used to transfer files, doesn't add much to what was already available.

Hence, the true value of NFC should be its ability to read RFID (Radio-Frequency Identification) tags. However, I have not been able to find any of these devices anywhere, and I'm not sure if it's because these are less used abroad where I am living or not. So, where can I find these devices?

# Answer
NFC tags are one type of RFID tags. NFC is a protocol for RFID, which can be understand by more and more devices. You can buy NFC tags on amazon or other websites.

What can I do with that tags? You can trigger something when you touch your phone to that tag. For example a NFC tag in your car which turns on Bluetooth, mutes your phone and turns off the lock screen. Then you can put the tag anywhere in your car and when you touch it your phone will be in your "car-mode" However this requires some apps to work. For example 'Trigger' (https://play.google.com/store/apps/details?id=com.jwsoft.nfcactionlauncher) or 'NFC Tasks' are great apps for this purpose.

Title: Samsung Note shutting off
I just purchased a Samsung Galaxy Note last night so I do not know much about the phone.
When handling and not charging it shuts off on me. It has charged and there is battery life of 70 lets say. When I try to turn it on my battery has completely ran out. Wont even turn on unless it is on the charger. I ordered a new battery but now I am not so sure that is my problem.
As you can imagine I am not a happy customer at this point and will more than likely not be buying from other people any longer. Any help would be just peachy. Thank you!

# Answer

Are you saying you bought a used phone from another person (not a store) like from ebay or craigslist?

If so, it could very likely be a worn out battery. If the phone was advertised as problem free and fully working, and especially if it was advertised as brand new when clearly not, you can pursue a return through whatever site you bought it from.

# Question
Title: "Low on storage space" But I have 1.7GB free space
I have a Alcatel OneTouch Star, Im running Android Jellybean the phone has 8 or 4GB storage Im not too sure but the low down is when i go into settings and look at how much free space i have it starts at 2MB then it changes to something like 250MB within a second then it changes to 1.7GB after 2-3 seconds. I have uninstalled all things I can, except for Facebook, Instagram and Snap chat. Its not the actual notification that Is bothering me, its the fact that I have 1.7GB of free space but the system doesn't let me download anything because it says that I don't have enough free space, so I think you can see why that would get on my wik, so can anybody help me? It would be much help

# Answer
I believe that most phones seem to like a certain amount of space free, to keep things running smoothly. If you try to downloaded something that would leave too little space free, it won't let you. Kind of like how Apple IOS system updates can required 4GB of free space though it may need less than 1GB in reality.

In any case, your phone is capable of using a removable microSD card, and with the piddly 4GB of internal storage- of which only 2.5GB are available to the end user, that is exactly what the phone makers are encouraging you to do. You should invest in a microSD they are available in large sizes- 32gb is the largest without needed to format the card.

# Question
Title: How do I cancel password request on my lock screen?
I have tried using the security features using Device Manager on my Hudl 2 to Sony Xperia E1 running 4.4.2 KitKat. When I tried the lock feature, it made my phone ask for the password, but is there now anyway to stop that as it is a pain every time my screen locks? I have tried settings - security - screen lock but the none option is greyed out. I have also tried the "clear credentials" option, but no change.

# Answer
> 1 votes
If you have lock screen options grayed out, that's usually enforced by some program that has been granted permission to act as a "device administrator". Most commonly, it's the stock Mail app if you are connecting to a corporate mail server, or some corporate security software you may have been asked to install if you're connecting to a company network.

Go to **Settings→Security→Device Administrators** and see if there are any applications listed with a check mark in the box on the right. If there are, you can try unchecking them one by one and going back to the Lock Screen settings each time to see which one is imposing the restriction.

**Be aware, however:** revoking an app's device administrator permission may result in loss of access to resources and/or the deletion of any data associated with that app. You *should* receive a warning/confirmation message if that is the case for a particular device administrator you're trying to deactivate. For example, if the Mail app became a device administrator as the result of configuring it to access a corporate Exchange account, you will lose access to the account and all data associated with that account will be deleted if you deactivate its device administrator status.

# Question
Title: How to turn-off WiFi when there's no Internet available on the connection?
I have a wifi hotspot that is always on **but sometimes internet isn't available within the connection**; in such a situations, the phone is connected as expected to the wifi hotspot but because there's no internet, apps can't check for updates(messages) so I wont be notified of incoming messages from IM apps unless I manually turn off wifi and use mobile data for internet connectivity(2g or 3g for example)

Is there any way to automatically check for internet availability (by pinging a website maybe) and if there's no internet available within the connected wifi network, turn the wifi off? (so that the phone can use mobile data for internet connectivity)

# Answer
should be capable of that. It can execute HTTP\_GET commands, and it can also deal with data connections; but for the latter, depending on the Android version you're running on your device, you might need root access to toggle data connection.

*Tasker* uses (combinations of) "conditions" (also called "context") to trigger "tasks" – which both together is called a "profile". So you would need a profile for that. Let's go step-by-step:

Your condition will be a time-based one, as you want to check connectivity periodically. Chose wisely here: checking too often might become a battery-drain – checking to rarely makes the whole thing useless. Play starting with 1 minute, and maybe go down to 30s if that's not enough.

The task then is a conditional one, which could be described as "switch off WiFi if I cannot reach the internet". So let's put that together:

* **Condition:**
    + Time.
    In the fields, define the time frame this should be active in, and the "repeat" interval.
    + WiFi connected.
    I recommend adding that to safe some juice: If you're already on mobile data with WiFi turned off, there's no need to turn WiFi off – right? Alternatively, you could also use `%WIFI ~ on` – but that could give you a headache when you just switch it on and, failing to retrieve the URL, *Tasker* switches it off before it connects ;)
* **Task:**
    + HTTP Get
    + WiFi (off) IF %HTTPR ~ -1

`%HTTPR` is a *Tasker* variable where the response code is stored into. According to the Tasker UserGuide, *A response code of -1 indicates a problem making the request.* This problem should be a timeout or "network unreachable" error (as a "not found" should be a "404" code), but you might need to play with this.

The above doesn't cover an "automatic return", so you had to enable WiFi manually (though that could be automated by a second "profile", periodically checking if things changed).

Every user of this tablet is having this issue. The company supposedly put out a firmware fix, but when you download the files to install it, they are corrupted. Which either means they are incompetent or purposely put out files that are corrupt so they can say "oh sorry" and never address the issue. Either way I'm not too optimistic.

# Question
Title: Name of the app which shows colorful Android and sweets in grid
Can someone help me what is the name of this app? I can't find the name of it. Is it a spyware?

# Answer
It's not malicious - it's part of an "easter egg" hidden in Android 4.4. You can access it by going into Settings → About and tapping on the "Android Version" quickly 4-5 times. Here is a demonstration on YouTube.

There are also some third-party apps on the Play Store that attempt to extract these easter eggs into portable apps, or use them for boot animations or daydream animations. Whether or not *those* are malicious is difficult to determine definitively, but you could probably hazard something of a guess based on the permissions the app requests.

The easter eggs have been of varying levels of complexity and interactivity. Lollipop's is basically an Android-themed Flappy Bird clone.

I bought an Asus Zenfone a few days ago and it was working well for 2 daysT the system asked to install an update and I agreed and installed it. Now the power button is not working at all.

Could it be a hardware or software issue? What should I do?

Device information:

I had the same problem. Was working fine until the update.

To fix it I had to reset the phone: Settings/Backup & reset. Make sure all of your data is backed up before you do it. After the reset it is working fine.

I considered running it flat & see if it would work on restart but if it didn't then it would be a lot harder to reset - manually through pc.

Hope this helps.

**Update**

I changed my case during this process & have just changed it back. Same symptoms started happening - it seems that the power button on the case is placing too much pressure on the switch & by picking up or moving the phone it is sometimes enough to activate the button. Changing the case back & everything works fine again.

My original case was fine. The problem one was the asus flip cover case. Looking inside at the buttons I noticed that the materials were slightly different.

I would suggest trying your phone without any case & see if you still get problems.

# Question
Title: Auto-hide notification bar while apps are opened
With a custom launcher, you can auto-hide the notification bar on the home screen and swipe down to make it re-appear. However, when you open an app, the notification bar re-appears.

Is there any way to hide the notification bar on a non-rooted device?

# Answer
**This feature is known as "immersive mode" and was first introduced in Android 4.4 KitKat.** It allows the app to hide the notification/status bar and even the navigation bar.

For the official method, the developers of the app need to implement this feature on their app. Though, some ROMs may also provide this feature built-in, sometimes also known as "expanded desktop mode", e.g. CyanogenMod/LineageOS, OnePlus.

Otherwise, some 3rd-party apps may help to force immersive mode in all apps:

Note that by using these apps, the keyboard may not work properly.

From BGR,

Title: How to permanently disable priority interruptions setting?
I'd like to revert to the pre-Android 5.0 Lollipop behaviour of having all notifications (including calls, messages and alerts) come through at all times. The problem is that whenever I configure the device to "always interrupt" after some time (usually in the order of hours) the device reverts to "priority" mode. This happens regardless whether I use the setting at `Settings / Sound & notification / Interruptions / When calls and notifications arrive / Always Interrupt` or `Volume button down / ALL`. How can I make the "always interrupt" setting stick permanently?

# Answer

I found the solutions to this. I use the Llama Android app to modify the volume, however, unfortunately there is a bug in Android 5.0 lollipop whereas silent profiles put the device in priority notification mode, but setting the profile back to normal volume does not change the notification priority mode. There is a fix in newer yet unpublished versions of Llama.

It also supports offline editing. You have to sync the content of your Drives first, but after that, you can edit it offline in Google Slides. The file will be synced to Drives when the internet connection is available.

# Question
Title: How to 'force' update apps?
I am currently using Huawei's smart phone. The has KitKat installed and it is rooted.

Huawei's app center shows that updates are available for a number of apps (not system) but the same apps updates are not available via Google Play Store.
I don't want to update my apps via App Center of Huawei.

Is it possible to force Google Play to check for update and then update the apps? Any app available for that?

# Answer
Some apps use the "staged rollout" feature of Google Play, which means that not all users get the update at the same time (I'm not entirely sure on exactly *how* it distributes the updates, but it does). So no, if the update is not shown in Google Play, the only way to get it is to wait.

However, APKMirror provides (some) APKs which you can manually install by downloading them onto your device and installing them

Note that "Unknown sources" should not need to be enabled, as the majority of these APKs seem to be the original, signed APKs - that is, the APK's cryptographic signature guarantees that it is unmodified from the company.

*How does this work?* I'm going to skim over the details, but essentially, the company that produces the app (for example, Google) has a secret "key" which they use to cryptographically sign the APK. Android checks that the new version of the APK is signed using the same key as the one that's installed (and that all the files within it match checksums provided by the APK), and if it doesn't (meaning that the APK has potentially been modified by some third party), it will refuse to install it.

# Question
Title: How remote control/remote desktop on Android works? (e.g. TeamViewer)
I am wondering how TeamViewer for Android and simple applications work. For instance, TeamViewer claims on its webpage that they can remotely control Android devices from Samsung, Lenovo, Sony, HTC, and many others.

I know that Samsung SAFE Devices have some API for this, but what about others? How is it possible to remotely control non-rooted Android device?

# Answer
> 0 votes
I haven't done much research specific to TeamViewer, but as an app developer, I'd say it's very possible with certain limitation. The key is, you also need to install certain app on Android device as the interface between PC\<-\>Android.

The Android SDK provides many things: given correct permissions, it can place a call, read/send messages, open app, read device's sensors, etc. If the app has Super User permission, then it will have greater capability.

If you look into the permission of TeamViewer app, you can more-or-less guess what features the remote app can do:

> Version 10.0.2555 can access:
>
> * Device & app history
>     + read sensitive log data
> * Identity
>     + find accounts on the device
> * Photos/Media/Files
>     + modify or delete the contents of your USB storage
>     + test access to protected storage
> * Wi-Fi connection information
>     + view Wi-Fi connections
> * Device ID & call information
>     + read phone status and identity
> * Other
>     + access SurfaceFlinger
>     + read frame buffer
>     + press keys and control buttons
>     + full network access
>     + prevent device from sleeping
>     + view network connections
>     + connect and disconnect from Wi-Fi
>     + pair with Bluetooth devices
>     + control vibration
>     + measure app storage space
>     + close other apps
>     + draw over other apps

Then, you have TeamViewer app installed on the PC. This works as a monitor/main control. Now, given 2 apps (PC and Android), both apps can communicate to each other (just like chat/messenger app). You can send a message from PC, then the Android app will receive the message, interpret it, and do something on the device. You can also request data from PC, then the Android app will again receive the message, interpret it, and send the data back to PC.

# Question
Title: keep recording audio even if camera takes photo
How can I take a photo without having to restart recording audio? I have a lecturer who's handwriting on the board must be deciphered after class, but I don't want to bring two devices to class, one for audio and one for photos. The stock software basically crashes the record app if the camera is started. I think my old flip-phone might have better multitasking...

Device in particular is a Samsung Galaxy Note 3, but I am curious about android devices in general.

# Answer
On my Samsung I9300 Galaxy S III with a Android 4.1.2, I use Camera Zoom FX (non-free): it can take pictures without stopping recordings done by Android's native voice recorder (unlike the native camera application).

# Answer
Do you use a third party application to voice record? If you disable the shutter sound and use something like Smart Voice Record, I'm able to successfully voice record and take pictures without a problem.

# Answer
Anyways, you can still probably just use Smart Voice Recorder anyways even with the Shutter on just turn the volume all the way down to silent.

# Answer
You can use Skyro Voice Recorder which does both voice recording and has ability to attach pictures to recordings. Now you can create nice lectures with audio and images synced.

It automatically attaches pictures taken during the recording to your audio, you can also add photos from gallery/dropbox/drive etc. Amazing app all these features are completely free. The new version of the app does it really well, automatically create a slideshow at the end of the recording with images taken during the recording.

# Question
Title: How to choose which contacts to download from google
I am using a really old version of Android (2.2.2). I have had it for about five years. It's an HTC Desire (the first ever). My contacts list in my phone keeps getting bigger and bigger (currently at 27mb) and I want to reduce it. I have my contacts synced with my google account so they are always backed up. But how can I choose which contacts it downloads to my phone? Everytime I send an email from my gmail a new contact is added and that contact is automatically downloaded to my phone. How can I stop this and only download the ones I tell it to download?

**EDIT** Forgot to mention, I want the ones that are created from my email activities to continue existing but only on my email account and on my phone contacts

# Answer
> 2 votes
I don't remember if you have that option in froyo. What I know is the following:

1) In gmail / settings / general, you can configure if you want new emails to be added to your contact list. These new contacts will be added as "other contacts", but won't have the label "my contacts", which is the main label that all your good contacts should have.

2) In lollipop, the contacts app, settings, you can configure which contacts to show: gmail contacts, whatsapp, .... Inside gmail, you can choose which contacts to show, and therefore, you can select "my contacts".

3) However, I doubt that this avoids downloading all the contacts. Probably is just a filter to show the ones you want.

4) I suggest adding as contacts those you need. It's fast of you hover the mouse over the email and go to "Add as a contact". The label "my contacts" will be added to it.

PS: 27 MB in contacts? That's a hell of a list!

# Question
Title: What do the application icons in the upper-left hand side of the notification panel mean?
On my Samsung Galaxy SIII, I am used to controlling which applications are running at any given time by holding the Home hardware button and then swiping any apps I want to close from the list of running apps that shows up. In the following screenshot, I have held down the Home hardware button and closed all running application by tapping the icon that shows up in the lower-right hand side consisting of a list with an X in front of it:

<sup>(click the image to see its larger variant)</sup>

However, what puzzles me is that no applications are running, therefore shouldn't those icons in the upper-left hand side of the notification bar disappear so as to tell the user that these apps are no longer running? Perhaps I have missed the purpose of those icons in the upper-left hand side of the notification bar.

Perhaps someone could explain what they mean.

# Answer
OK, I figured out, those icons do not correspond to which applications are running, but rather, to those applications which have awaiting new information for the user. When the user drags the notification panel from the top of the screen, those same icons appear next to the name of the application sending the notification and the message posted by such application also appears next to the application name in the list. This should answer the question.

# Question
Title: How to disable haptic feedback for (software) keyboard?
On my Samsung Galaxy SIII, when the screen is unlocked, by default when the user presses any of the hardware keys Menu (the key on the left) or Back (the key on the right) the phone virates slightly and then if the user keeps holding such buttons then the phone emits another slight vibration corresponding to the long press, and the same happens when the user long-presses the Home hardware key (the key in the middle).

Since I didn't like this bahavior I went to `Settings -> My device -> Power saving mode (turned it on) -> Turn off haptic feedback (made sure this checkbox was checked)`. This disabled the slight vibration occurring when the above-mentioned hardware buttons are pressed, but the phone still vibrates slightly when the buttons on the software keyboard are pressed.

Is there a way to disable haptic feedback for the software keybaord as well?

Thanks.

# Answer
This should work:

Go to `Settings > Language and Input`. Click the settings icon on the Samsung keyboard, go to `Advanced` and uncheck `Vibration`.

Title: Can't add hotmail.com address into Gmail 5.0
I tried under KitKat and Lollipop on my Nexus 4 but I can't add my old account. I also tried both manual and automatic setup, but same result: credentials are incorrect.

Any solutions about this? Should I have entered different parameters during the manual setup?

EDIT:

Do you have two-step verification enabled on your hotmail account? If you do, that extra layer of security can trip up GMail. You'll need to create an "App Password", which should be a setting in your Hotmail settings.

From Microsoft's Two-step Verification FAQ:

> Some apps (like the mail apps on some smartphones) or devices (like the Xbox 360, for example) can't prompt you to enter a security code when you try to sign in. If you get an incorrect password error with an app or device, you'll need to create a unique app password to sign in. Once you've signed in with your app password, you're all set to use that app or device. You'll need to create and sign in with an app password once for each app or device that can't prompt you for a security code.

Try these steps as seen @ how-to-set-up-hotmail-on-android:
...
...

1) Tap on “Email” in your app drawer

2) You should see the Email Setup screen. Type in your email address and password. Tap Next.

* If you encounter an error, repeat Steps 1 and 2 (DON’T press Next). Move on to Step 3.

3) Once you’ve typed in your details, tap on “Manual Setup”.

4) Select “Exchange” from the list of options.

5) Fill out the fields as indicated below in the Account Setup window:

```
Domain\Username: delete the “\” and type in your full email address
Password: type in your Hotmail password
Server: type in “debug-m.hotmail.com”.
    If that doesn’t work, repeat Steps 1 – 4 and use “m.hotmail.com”
    If that doesn’t work either, repeat Steps 1 – 4 and use “blu-m.hot mail.com”
Make sure the Security Type is “SSL/TLS”

```

6) Tap on “Next”.

7) Choose whatever options you want (how frequently it should check for email, how much it should sync etc.). Tap on “Next”.

8) A little loading icon may appear as it syncs your email account.

9) Congratulations! Your email is all set up and you can now set a name for the mailbox.

Your account should be completely set up by now. It should be syncing your email as you read this very sentence. Once again, this setup has only been tested on @hotmail.com and @hotmail.co.uk accounts.

... ...

*Alternatively, you can always create a new GMail account and integrate your hotmail one with it (Allow you to seen your hotmail emails inside the GMail interface) as seen @ guidingtech.com and then add the GMail account.*

# Question
Title: How to switch user profile based on password / lockscreen pattern
Currently, I have a family use tablet running on 4.2 Jellybean

Model is Ainol Novo7 Flame, a cheap Nexus7 alternative. Nexus7 is quite expensive in my country on its release so I bought this one instead.

The problem is that the tablet is shared. I already set-up multi-user profiles for each of us.

1. Family mode
2. My mode
3. My sister's mode

The default user set is family but I want it to automatically switch user-profiles based on the entered password or pattern lock.

example: password `1358` triggers `My mode` while entering `2467` triggers `My sister's mode` profile

I would also like to have an option to lock certain apps automatically when in `family mode` but unlocked in `My mode`

Is there a way to do this? or is there an app that can closely do some of it?

# Answer
> 1 votes
I'm not sure automatic password detection is available. After all, computers don't really have that function. You still have to select the user/enter username.

As far as having the option to lock certain apps automatically when in family mode but unlocked in My mode, upgrade your Android version at least 4.3 (newest is Lollipop 5.0 but that's not available across all devices yet- 4.4.4 KitKat is widely available).

This will give you access to a new profile/user type: **Restricted Profiles**.

From Google's help pages: About restricted profiles

> As the tablet owner, you can create restricted profiles that limit the access that others have to features and content on your tablet. For example, you can create restricted profiles to prevent family members who may have access to your tablet from viewing mature content.
>
> You can use restricted profiles for several purposes, including these:
>
> * Parental controls. Selectively restrict family members from accessing mature content.
> * Kiosk. Set up the tablet to demonstrate selected apps and features to customers.
> * Retail. Let customers explore tablet features, but prevent them from browsing or playing games.
> * Point of sale. Limit employees to the use of selected sales and register apps.

To set up a restricted profile:

> Note: You must be the tablet owner to create a restricted profile.
>
> 1. Touch Settings \> Users \> Add user or profile.
> 2. Touch Restricted profile, and the new profile with a list of settings displays. To name the profile, touch New profile.
> 3. Using the ON/OFF toggles and Settings , select the features and settings you want to grant access to.
>
> To set up the new profile, press the Power button to return to the lock screen, then touch the new profile icon.
>
> When the restricted user finishes setting up, the Home screen is empty. The granted apps appear after the user touches the All Apps icon .

Go to **Settings \>\> Security \>\> Device Administrators.** See if anything other than Android Device Manager is checked. If something is checked, it's possible it's forcing a higher level of security.

Uncheck it if there is, and check the screen lock options again.

Also try **Settings \>\> Security \>\> Clear credentials**.

If it's rebooting, you should probably try logging some kernel or other system related messages that are saved after / during a crash, that could show later log messages which probably show what crashed in the lower layers.

Include the log directly before the crash and include it here if it doesn't break formatting, or upload it on pastebin or nopaste (larger size limit) if it does.

Try to gather as much information as possible and include these in your question.
Take a quick look at this for your question to be more likely to get answers :)
Also tell us: What version of Android or what custom ROM / recovery / etc. are you running exactly?
What did you do before this happened?
What did you already tried?

# Question
Title: ICE Emergency Contacts on Emergency Dialer Screen
On my Samsung Galaxy S 4, I can add contacts to the "ICE - emergency contacts" group. When I initiate the emergency dialer, there are four gray buttons with plus signs. Pressing any one of them brings up a list of the contacts I added to that group.

Each of the buttons acts the same. I would think that you should be able to assign one contact per button and have the button show a name or relation.

Is it possible to do this? How?

# Answer
> 5 votes
Once you hit the gray box & that ICE list pops up, I believe you just have to select a contact from that list in order to assign that person/phone number to the box.

Just be careful with assigning contacts to the gray boxes because it can be very easy to pocket dial these people. In case you're interested in removing someone from the gray box, you select the menu button while on the "Emergency Dialer" screen & it'll give the option to remove the contact from the gray box.

Hope it helps.

# Answer
> 3 votes
Just a wild guess:

* Open Contacts app
* Long-press a contact so that a menu appears
* Click Edit
* Click Groups
* Check ICE - emergency contacts

*Although I have an S4, I can't try it on my phone due to some security settings.*

# Answer

While phone is locked, hit the "Emergency call" option, when it opens hit the settings/menu (left of the home button) on the device. You will see "Remove" appear at the bottom of the screen. Select "Remove" then you will see checkboxes next to the contacts. Select the contacts to be removed and then check the "Check Mark" at the top right side of the screen. This will remove those contacts from there, but not from your ICE group.

# Answer

Go to Contacts → Groups and you will see a group named "ICE - Emergency Contacts". Add your emergency numbers there and now you can access them from outer screen.

Title: I forgot my password
I had set a security password on my Samsung Galaxy S Duos mobile and unfortunately forgot the unlock password.

Go to https://www.google.com/android/devicemanager

Provided you have your phone set up with your Google account, it should show up on that page. Choose the **LOCK** option. It'll ask you to set a new pincode (and message if you want). As soon as you hit "lock" after entering in the new pin, the phone will lock with the new pin. Now just try to unlock your phone again.

That feature is really supposed to be a way to remotely lock your phone if it gets lost/stolen and doesn't already have a pin/password lock on it, but its a handy little workaround for resetting your pin if you forgot it.

...
...
Another option is through Samsung's Find My Mobile site.
The guide for your model shows two possibilities:

* **Lock my device:** Locks your device by setting a 4 digit PIN to prevent other people from operating your device.
* **Unlock my screen:** Initializes the security lock settings such as the screen lock pattern, password and PIN to unlock the screen of your device. Since this function initializes the device's screen lock setting, you must set the screen lock setting again. The screen lock set by the device or remotely set by the Lock my screen function will be released.

...
...

*If none of this works, I'm afraid you may be looking at a factory reset.*

# Question
Title: USB debugging on Samsung Galaxy Tab -- How do I prevent it from resetting debug setting?
I have a Samsung Galaxy tab that I'm using for development purposes. For some reason, when I choose 'Enable USB Debugging' in the settings menu, it turns off after a random period and drops whatever USB connection I have.

I'm debugging on a Macbook Pro, and have one coworker who has similar problems. Other coworkers don't have this issue.

# Answer
I also see this. I doubt it's the USB connection or the rest of the setup because I can develop & debug for hours with a Moto Droid connected to the same system. Galaxy Tab drops out of USB mode spontaneously after about a minute. Only way to get it back is to unplug the cable, re-enable USB debugging, and reconnect.

One way to keep the Galaxy Tab connected is to click the entry with its serial number in the Devices pane in Eclipse whenever it goes grey. That's only a little less annoying than cycling the USB cable and the debug setting on the Tab because if you wait too long, the Tab disconnects and its entry disappears from Devices.
> 3 votes

# Answer
Well, I figured out how to get it to stop unchecking the box, though the solution is hardly much less a pain.

If you activate the debugging mode, plug in the cable, run your test and then as soon as you're done testing (or if you're not actually debugging, as soon as the app is installed), unplug it, the checkbox will stay checked indefinitely.

You're still replugging the device every re-compile, but at least you don't have to keep going back to the settings menu to re-check the box.

Such entry reads: "Incoming calls and new notifications will be read out automatically".

As I was saying, however I didn't hear any voice coming from the phone reading out the notifications aloud, so it seems like this feature is not working for me.

What am I doing wrong?

Thanks.

I've got the same phone running android 4.4.2. My phone does not speak email messages. It only speaks sms text, caller id info, and two other notifications. If you consult the help manual on the phone, the usage is a little clearer.

Title: Contacts app: Groups: ICE - emergency contacts: What is the purpose of this stock integrated group?
On my Samsung Galaxy SIII, when I go to `Contacts -> Groups` there is a special stock group called `ICE - emergency contacts`. I have looked for the meaning of ICE on Wikipedia but was not able to find a definition that pertains to mobile phones or contacts. So I would like to ask the following questions:

1. What does ICE stand for (and what is ICE)?
2. What is the purpose of the `ICE - emergency contacts` group. According to this post, on the Samsung Galaxy S4 this creates special buttons on the `Phone` app's `Keypad` tab, but after adding the emergency contacts on my Samsung Galaxy SIII I don't get any extra buttons on the dialler.

Here are the screenshot of the Contacts -\> Groups screen displaying the ICE - emergency contacts and the unaffected phone dialler once the emergency contacts have been added.

Click for full size

Thanks.

EDIT: In the screenshot above the emergency contacts may not be showing up because the dialer is the regular dialer invoked from the Phone application's Keypad tab. When the lock screen asks you to enter a PIN number, the lock screen also displays a message saying `SIM card is locked - Emergency calls only`, and below that the user can click on the text `Emergency call` to bring up the `Emergency dialer` application which looks similar but is a separate application as shown below:

As the picture on the right shows, once I click the button on the lower-left hand side of the emergency dialer, even though I have Mobile Network Data enabled as shown below, given that I did not top-up my phone, I get the "Unable to call personal emergency contact. Network not available." message. I'm not sure whether that was supposed to bring up a list of my ICE contacts. Perhaps someone can verify this for me.

As far as I understand, this means that even if I find myself in an emergency situation, if I haven't topped up my phone then I will still be unable to call my emergency contacts, although perhaps one can still call some other numbers such as 911 or their equivalents overseas, whatever those may be. I haven't tried this, because I don't want to bother anyone with a purposeless call, but would like to know if such numbers work even when the phone hasn't been topped up.

Once the PIN number has been entered, the lock screen on my phone changes to the following and it is not possible to access the emergency dialer application:

Thanks.

EDIT:

I've now topped up my phone and was able to figure out the following: even when the phone has credit with the network operator, if the phone has just been booted then by default the PIN number will have to be entered to unlock the SIM card at the "Enter PIN to unlock SIM card" message, otherwise it will still not be possible for anyone to access the numbers in the ICE contact list. For as long as the SIM card lock feature is enabled, which I believe it is by default, and the SIM card is locked, the only numbers that can be dialed from the Emergency dialer screen are 911/112-type calls. It is possible to disable `SIM card lock` in `Settings -> More -> Security -> SIM card lock -> Set up SIM card lock -> Lock SIM card [ ]`.

There is also a separate PIN that can be enabled in `Settings -> My device -> Lock screen -> Screen security -> Screen lock -> PIN (Medium to high security)`. When this setting is enabled (by default the `Screen lock` feature is set to `Swipe (No security)`), the device owner needs to enter the SIM card's PIN at the "Enter PIN to unlock SIM card" message once the device boots, if the feature is enabled, followed by the screen lock PIN at the "Enter unlock PIN" message, and, every time the phone goes blank, to access the Home screen the screen lock PIN needs to be entered again.

Only once the SIM card is in an unlocked state can calls to members of the ICE list be carried out in addition to 911/112-type numbers. The "Emergency dialer" can be accessed from both the SIM unlock screen, in which case pressing the "person with ambulance light" button in the lower-left hand corner displays the message "Unable to call personal emergency contact, as well as from the screen unlock screen, in which case "person with ambulance light" button in the lower-left hand corner displays the list of ICE emergency contacts which can be reached.

Regards.

Title: Can I connect Gamepad for Nexus Player on smartphone?
With the new gamepad for the Nexus Player that came out earlier this year, can we connect this gamepad to a smartphone like the Nexus 5 to play games or it only connects to the Nexus Player? It uses Bluetooth 3.0, at first sight it should work but maybe it uses a different Bluetooth protocol just like the PS3 controller.

Yes. You put the gamepad into pairing mode by holding down the home button + the back button for 5 seconds, until you see the blue lights flashing, and connecting to the gamepad in the Bluetooth settings in your smartphone.

Title: Can I use an iPhone 4 micro-SIM card on Samsung Galaxy S?
I borrowed a Samsung Galaxy S device in order to test an app. I have attempted to insert my iPhone 4 sim card (micro-SIM) into the Galaxy S, yet the device won't recognize it and display a 'No SIM' error. Is the Galaxy S compatible with micro-SIM or do I need to purchase a different one?

# Answer
The Samsung Galaxy S (not S2; S3; S4 or S5) uses a mini-SIM. The iPhone 4 uses a micro-SIM. Maybe Robert's answer, well, kind of missed the wood for the trees.

Sadly, most of the SIM card mobile service providers have recently taken to heavy-handed self-protection tactics to retain their market share.

Most carriers have "tweaked" their SIM cards so you generally MUST purchase a SIM card that matches not only the service provider, but also the device configuration for which it was engineered.

While there might be a way to Flash a SIM card, but a new SIM card is so cheap it is not worth it.

Besides, SIM cards must be compatible with the device as well as the carrier.

For example, Simple Mobile is a subsidiary of T-Mobile and they both use SIM cards similar to Verizon's, however, none of these are "fully interoperable" with each other, as Verizon uses a different radio frequency for their LTE/4G or whatever thay are calling it now. Some SIM's from carrier "A" work on carrier "B" but not the other way around...

I am just waiting for a carrier that does not bother to collect my metadata.

If they didn't bother with all that overhead, our service would be dirt cheap...
