I have a Samsung Note 8. I took my phone to the store yesterday, and now I have a second lock screen with ads. I have gone through all of my apps that I dont regularly use, and have tried cleaning up junk files off of my phone, but nothing has worked. Does anyone know a way to get rid of this screen?
I think my device got a malware. A lock screen with ads sometimes appear, and I must swipe an area at the bottom of the screen to open the phone. I am in Eastern Europe, some ads are in Slavic languages, and they are seemingly related to travel.    Image resized. Click to view the full image  I have seen ads for Lot Air (Polish carrier). I recently went to their site.  Considering my recent surfing activity and the nature of the ads, I guess the malware is connected to airlines active in Eastern Europe.  The lock screen also promotes the app "DU Quick Charger" by claiming it has recharged the phone extra fast during screen off. (!?) It also shows battery level. I have never installed DU Quick Charger. I doubt DU Quick Charger is installed on the phone.  The problem started after installing Ryanair app. The problem is maybe, but not surely, related to this. Uninstalling Ryanair and restarting the phone doesn't remove the occasional appearance of this lock screen. After a while the situation has changed for the worse, now this lock screen appears after EVERY screen off.  I have always used Avast. I am not rooted and only install via Google Play.  What is this? And how do I remove it?
How do I find a command if I don't know its name? As a Unix beginner, I often find myself wanting to know the name of the command that achieves a particular function I'm after. How can I go about finding out the name of the command, given a description of what it does? Accessing AWS S3 via a REST API (Apex callout with a Named Credential) Grub not showing on startup for Windows 8.1 Ubuntu 13.10 Dual boot Can the Detect Magic spell detect prepared spells or spellcasters? Inspired by a recent question about discerning divine and arcane spellcasters, of like to hear the case for and against detecting spellcasters of either style with .  I think you can detect whether someone has prepared spells, based on this language:     For the duration, you sense the presence of magic within 30 feet of you. If you sense magic in this way, you can use your action to see a faint aura around any visible creature or object in the area that bears magic, and you learn its school of magic, if any. (emphasis mine)   Preparing spells is described as having the spell "fixed in mind" (). I'd argue that qualifies as bearing magic, and opens the door to using detect magic to identify spellcasters with currently prepared spells. What do you think? When editing really long code blocks (which should definitely be refactored anyway, but that's beyond the scope of this question), I often long for the ability to collapse statement blocks like one can collapse function blocks.  That is to say, it would be great if the minus icon appeared on the code outline for everything enclosed in braces.  It seems to appear for functions, classes, regions, namespaces, usings, but not for conditional or iterative blocks.  It would be fantastic if I could collapse things like ifs, switches, foreaches, that kind of thing!  Googling into that a bit, I discovered that apparently C++ outlining in VS allows this but C# outlining in VS does not.  I don't really get why.  Even notepad++ will so these collapses if I select the C# formatting, so I don't get why Visual Studio doesn't.  Does anyone know of a VS2008 add-in that will enable this behavior?  Or some sort of hidden setting for it?  Edited to add: inserting regions is of course an option and it did already occur to me, but quite frankly, I shouldn't have to wrap things in a region that are already wrapped in braces... if I was going to edit the existing code, I would just refactor it to have better separation of concern anyway. ("wrapping" with new methods instead of regions ;) Should I get Enlightened badge? Today I've got 10 upvotes for an answer. Answer was a first answer in the question.

(I also have a Godox V1, which is a beautiful thing!) I have the Canon Speedlite attached to the Godox receiver, so it should fire. It just wont! How do I set it up correctly so the receiver makes the Canon Speedlite fire?  Update: Michael C answered this question. I had the ID numbers set differently on the transmitter and receiver. I made them the same and now it all works. Perfect! Thanks Michael!! Why are NginX and Lighttpd not affected by Slowloris? I am investigating the vulnerability to  and I think I understand how and why this sort of attack works.  What I don't understand is why Lighttpd and NginX are not affected (according to the same article as linked above). What do they make so different? Helpless after exhausting daily limit for reviewing Suggested Edits I have faced this problem earlier. But today I got to face this problem twice in a span of couple of minutes.. I have unfortunately finished my daily quota of reviewing Suggested Edits. But I want to further edit a post for which an edit has already been suggested by another user having less than 2000 Reputation.  I come across a post and it says that an edit has already been suggested which is pending for Review:   I click on edit (1) and a pop-up of Suggested Edit appears:    However, the problem is this Suggested Edit doesn't thoroughly deal with the post. It just fixes some capitalization and nothing else — no grammar fixes, no sentence restructuring to make it more clear, no code formatting, no dividing it into lists, etc. — in short, perfect candidate to be rejected. (The image for the suggested-edit I have uploaded didn't have those problems - however, there were those problems in the edits that I encountered earlier.) The problem before me is that I am helpless. I can't approve, reject or improve the edit since I have already gone past my daily quota of Reviewing them. Neither can I make the edits to the post since this suggested edit is pending review. I am completely helpless!! Whats the opinion of the community in this matter?  Should we (those with more than 2000 Rep) be able to edit them? Don't count it in our Review Progress obviously - not sure what should be done with the suggested edit already proposed.  Or, Let it be, someone else would come and edit them and other Reviewers would deal with the Suggested Edit appropriately.  Or, Something else.

So, treat it as a question posted at Meta.SE and not so much at Meta.SO.  Dirty Hack: Ah... found a dirty hack to work around this situation.

Bottom to top explanation of the Mahalanobis distance? I understand why the Empire would want to start using more than one genetic template to create clone troopers, but why did it start using non-clone troopers instead of just continuing the cloning program?  It seems that with cloning they were able to use a training program (and genetic manipulation) that gave them completely loyalty (other than when the Kaminoan rebellion, where the Kaminoans had sabotaged the training programs).  Why stop using such troops and start using people that might question orders or aren't as easily controlled as clones were? If $f:\mathbb{R}\rightarrow \mathbb{R}$ is differentiable and $\lim_{x\to \infty } f^\prime(x)=0$ show that $\lim _{x\to \infty } (f(x+1)-f(x))=0$. Piping for loop output prevents local variable modification How far can one get in analysis without leaving $\mathbb{Q}$? Suppose you're trying to teach analysis to a stubborn algebraist who refuses to acknowledge the existence of any characteristic $0$ field other than $\mathbb{Q}$.  How ugly are things going to get for him?  The algebraist argues that the real numbers are a silly construction because any real number can be approximated to arbitrarily high precision by the rational numbers - i.e., given any real number $r$ and any $\epsilon&gt;0$, the set $\left\{x\in\mathbb{Q}:\left|x-r\right|&lt;\epsilon\right\}$ is nonempty, thus sating the mad gods of algebra.  As @J.M. and @75064 pointed out to me in chat, we do start having some topology problems, for example that $f(x)=x^2$ and $g(x)=2$ are nonintersecting functions in $\mathbb{Q}$.  They do, however, come arbitrarily close to intersecting, i.e. given any $\epsilon&gt;0$ there exist rational solutions to $\left|2-x^2\right|&lt;\epsilon$.  The algebraist doesn't find this totally unsatisfying.     Where is this guy really going to start running into trouble?  Are there definitions in analysis which simply can't be reasonably formulated without leaving the rational numbers?  Which concepts would be particularly difficult to understand without the rest of the reals? Why isn't Derivative equal to NeumannValue? Which commit has this blob?

As far as we know the gaze of the basilisk will instantly kill someone or eventually petrify him/her in case the gaze is somehow softened or reflected.   But why would it melt the film in Colin's camera? The film is just plastics with some specific chemicals.   A bit broader question would be - is the some information that the basilisk's gaze is somehow destructive to non-alive objects too and under what circumstances could it happen?

Recently I've been toying the idea of abolishing a level system. However, I don't want to remove the ability for a player to multi-class. Are there any games which don't have a levelling system, yet allow multi-classing? How do they do it successfully? How do I Insert a carriage return on a card in Trello?
