[Q] Back Key behavior can be modified? - Galaxy S 4 Q&A, Help & Troubleshooting

So i have a galaxy s4. i had a idea, about pausing the process when leaving an app when hittin back button instead of destroying it.
when we open any app , bbm, facebook. games, twitter por example. and when we go out from it by pressing continously the back key, when we try to open the app again it will take more time than if we tap the home button.
basically home button tells android to pause the process and backbutton to close it which require more time when reloading the same app again.
i beleave this is not a remmaping thing because the back button will still going steps back in the apps, so, when there is no more steps to go back then it will pause it (not close it) ; home button will remain the same, pausing all apps to go home screen. and back button will pause only the one we are on (instead of closing it)
i repeat a lot the same thing because i want to be very clear. dont take it bad please.
Is this possible to make? may any of you give me some advices to do it?

My Tab can take screenshots...but I don't know how

Ok, something really weird.
Yesterday, I was showing off my Tab to a friend, and we kind of got stuck on comparing how fast the portrait/landscape switch works on ADW launcher vs. stock touchwiz. So we were tipping the device back and forth for a while when it froze for a few seconds.
Trying to get it to react, I hit back, home, power, probably in that order, but I'm not sure.
The reaction, a message pops up about the image capture being saved. Then again. And indeed, in my Gallery I now have a folder call Screen Captures and inside it there are two screenshots. One of my standard homescreen and one of a force close error message (for the calculator app I use - Kreac).
I've been trying to reproduce this since, but without any success. Is there a hidden screenshot app in there somewhere?
Hi , just keep pressing the back button and double press the power button to take screenshots.

Indeed.
Is this common knowledge that I had missed? I ask because I've seen several threads on various forums claiming that there is no app and no way to take a screenshot?
Interesting. Is there a service running that handles this feature or is it a core process?
Don't know. But I just noticed there's an entry 'com.sec.android.app.screencapture' in the application manager list.

i remember it... but ive removed it now and theres no apk, so theres no way to restore without flashing
i was trying screens with one of the root apps on the market and they all came out in funky colors so i got rid of it (must have taken sammys built in app out as well by mistake)
IMHO, best way to take screenshot on any device, galaxy tab included, is via ddms.bat ( Dalvik Debug Monitor) under dir tools of SDK. You can find "screen capture" under Device menu.
Can't for the life of me see how using DDMS can be "better" than this on-device method in general use!
This is a good find - we need a sticky for these tidbits!

It's a good tip, but I much prefer using DropCap 2 from the Market, at least for when I'm not using a full-screen application. Talking of which, are in-game screenshots possible with the hardware button method ?
I was able to capture a screen shot by pressing back and then pressing the power button twice. But that does not capture the screen that I wanted. Instead, it captured the screen of "back" when I press the back button.
This button combination does not make much sense in my opinion. Any say?
It works fine for me in most apps (including Angry Birds), but not in the stock Video player or in the Gameloft games like N.O.V.A.

Is there any other way to do it ? Ad soon as I hit back it goes back to the previous screen and take screenshot of that screen. Isnt that kinda pointless?

For this cases I suggest ddms in the previous post. ddms don't need any user interface and grab everything, also video played in stock video player. And grabbed screenshot can be saved directly on HD, rotated, discarded...
I find that "holding" the back button down until vibrates (rather than merely just pressing it) and then pressing the power button just once works consistently well for me. Haven't needed DDMS yet.
For me it works fine; keep pressing back and tap power button.

Hit back and power at the same time... and then hit power again... and you hear a sound like a camera shutter... and says it's saved.
Dear all
Very simple
. Press and hold back key
. Short press power key
screen will automatic save in folder Screen picture

Ok, I got it now. The theory is to hold the back button and do not let go until you hit the power button twice. It works!! But it takes quite a while for the picture to show up in the Gallery. I thought the screen capture did not work.
SOLVED: How to screen capture if Back key exits from the current screen
I just solved how to capture the screen if holding down the Back key exits from the application so you end up capturing the previous screen, or the Home screen in most cases.
For example, in Maps, I couldn't capture the Map as it goes back to the Home screen once I hold down the back key. The technique is to go one screen deeper; example in Maps, press Menu key then select Layers. When you hold down the Back key, the Maps image screen is displayed. Keep holding the Back key then press the Power key. Screen capture now completed on the desired screen.
I think you can do the same technique for other apps.
Hope you enjoy using your Galaxy tab as much as I do, like me having sleepless nights on the porch using Google sky map, or playing Guitar solo (paid version is much better).

That's strange... it should not go back until you have taken your finger off the back button and if you hit the power button whilst holding the back button it should cancel out any back button command.

Froyo Screenshot Keystroke bug

Not so much a bug as a real doh! moment.
Froyo for the Galaxy S lets you take Screenshots
Problem is the keystroke is Back key and Home button.
Anyone got any tips for preventing the back button from taking you back as soon as you touch it? I managed to take a screenshot of one app but now all I get is screenshots of my home page as the back buttons quits the app.
It's a pain when the phone locks up sometimes, mostly in when cycling through my emails. I try clicking the home button to get back to the homescreen, but the back button seems to be stuck 'on', so I end up taking loads of screenshots of my emails!
I was in a queue the other day and it happened, and the camera 'shutter' sound kept going off. People thought I was taking photos of them!
I'm hoping someone finds a way to change the keystrokes. Whoever chose the back key and the home key just hasn't mastered joined-up-thinking yet.

Maybe you have not mastered pressing two buttons at the same time.
it's not about pressing the two buttons at the same time, screen capture happens only if you press the back button first, holding on and pressing the home key.
Quite. The back button always takes you back, which in most programs is to one of the home pages.
I have discovered Screen Shot It, which seems to be the only one that works on non-rooted phones.

When I hold down the back button it doesn't go back. Maybe just a bug in the specific firmware you're using.
It only goes back for me if I tap it.

THIS. I tried reproducing the problem in various applications (and even the lock screen). As long as you don't release the Back button before you press Home, it always takes a screen-shot instead of going back or triggering the Home button action.
Conceivably, an application might be able to map the 'on-hold' event for the Back key for something else, but at least I haven't come across any app like that (well, maybe ScummVM - but I don't have that installed right now).
It does appear to be hit'n'miss depending on what application you are in. From many it works as described, but I just tried in the game "Scrambled Net" and hitting the back button and keeping it down still takes me back. Will be keeping ShootMe for now as a backup, though I prefer its use of "shake" to peform the shot.
I have been holding the back button. Results are varied. Just tried it in Tapatalk. When in a thread pressing and holding the back button takes you back to the threads screen. Then you can take a screenshot. Accuweather worked for me once but the back button always takes me back to the home screen.
Screenshot it works on unrooted Samsung Galaxy S with Froyo (i9000M)
Woot!
The correct method to take a screen shot it to hold the back button then press the home key. When I have seen people failing to take screen shots it's because they have been trying to press the buttons at the same time.

Some apps take you back before you release the button.

Delay when pressing home button - how to fix.

Since upgrading to a stock Jelly Bean firmware, I noticed that pressing the home button causes a short 1 second delay before it actually does anything. It's enough to be annoying since it slows down returning to the home screen or moving to the default home screen.
The reason for the delay appears to be that it's waiting to see if you're going to make it a double-click. A double click launches the dreaded Vlingo voice control app or Google search dial by voice.
You can remove the delay by installing Advanced Home Button from the play store, and following the "Galaxy S2 hack" instructions within that app.
Now, pressing home instantly takes you to the home screen without the one-second delay.
The downside to this solution is that you lose the double-click functionality on the home button, but most people probably see that as a benefit anyway.
I am not the author of that app, nor do I know how it works or how to reverse it.
Or you can delete both and no more 1sec delay

[Q] Home Button Responsiveness

Is anyone having issues with the home button? I will tap the home button to go to the home screen, but instead, it will take me to the recent apps menu about half the time. This is getting really annoying, and I'd like to get it fixed.
Does anyone else have this issue/know how to fix it? Is this a software or hardware issue?

Sounds like a mix of software / user issue to me.
I was doing the same thing so try this and see if it feels better.
--
With default settings a quick tap will bring you home after about 1.5 seconds
holding it brings up your recent apps, it sounds like you're holding it for the 1.5 seconds as you're expecting a delay for it to go to the home screen and its causing it to open up recent apps.
To remove this 1.5 second delay double tap home quickly and open up S-Voice, when S-Voice opens hit your menu button and turn off the double tap home to open, then close the app.
Now when you hit home there will be no delay as the system doesn't pause to wait for a second tap to open up s-voice and it just goes home. it also means you won't feel the need to hold it until it goes home inadvertently causing you to open up multitasking instead.

Button to quit an unresponsive app?

I have a stock Nexus 6P with Marshmallow's February update.
Is there any key that will allow me to exit an app that isn't working proprely? Previously I had an HTC One M8 with ViperOneM8 ROM. That allowed me to long press the back button to close an app.
I have a game that has gotten stuck after their update. This happened in the past. The game says Touch Screen, but it doesn't respond. If I hit the back button it gives me the open that No I don't want to quit or Yes I want to quit, but it's unresponsive.
If the Recent apps button isn't working maybe long-pressing the power button will have some impact.
I thought the square button was just a list of recent apps, not a list of apps currently running, so I never thought to use it. I just figured that button is to clear stuff out of history. I mean, because there's a ton of stuff in there and I know 100% not all that is running at one time.
The home button.

The home button doesn't CLOSE the app, though, like a force close or whatever you want to call it. That just minimizes the app so you can see your home screen or open other apps, but the app is still running in the background. If you re-open the app you're still stick at the screen that didn't work in the first place.
What the previous person said works, though..
Well of you can hit the home button and then get into settings, just go to apps tap on the app and hit force close
Hit the recent apps button (square one lol) and just swipe the app away... It will close it.
