BACK-Button to kill a task *searching*

Hi there,
wondering if there is a way to get the back-button finishing the app.
When i'm at contacts or writing an sms or surfing, i want to go back to desktop as fast as possible...but when i'm at contact/details, i have to press the back button 5-6 times to go back trough all the previous screen.
Is there a way/hack/app telling the back-button (have to be a hardware button) to end the tasks completly when holding it, for example?
THX THX

Press the home button? That will take you back to the desktop.
If you need to you can then use task manager to end the task.
Would be nice to see a hack/fix to add the back button to kill functionality though

It's already in in MIUI and most probably will be also in CM7.

well the back button does kill apps.
if you start, say, the browser and press the home button, then enter task manager, the browser will still run. if you start the browser and press the back button and open the task manager, it will show that the browser is not running anymore (actually, the browser was a bad example, since after a little bit of browsing you'd have to push the back button quite a lot since its primary function is to go back). the same goes for many more apps, whatsapp, facebook, twitter, angry birds...

me too. adamG has apparently got a SGS2 though

Thinking about it, I would also like this functionality although it isn't so urgent for me. If more people show interest maybe I'll attempt it as my first android app For such a simple app my opinion is that it should be free and not packed with admob spam, but if another dev wants to attempt it that's their choice I guess.
My thoughts:
It should be quick to develop a simple app providing this functionality. Just have it bind to an event which fires when the back button is pressed long, and have it kill the app whichever is first in the foreground window Z-order (I'm fairly new to the Android API, so I use Win32 API terminology here for example only). The only complexity may be to make the event bound globally (in all apps), as opposed to only bound in the app itself - hopefully that doesn't require root! I guess it should be a background service which runs on boot, and perhaps a very simple gui app to control that service (in fact would there be anything to configure at all? What do you think?).

It would need to be in the framework of the rom, I think

Yeah it does, but you have to press and press and press...would be cool, if you can "hold down" the button for a sec and it will end the task.
Example...when i'm at handsentSMS > SMS > keyboard open...
Pressing BACK > close keyboard
Pressing BACK > closing SMS windows
Pressing BACK > closing handsentSMS
3 times pressing this button after every SMS suxx...sorry
Yeah i can press the HomeButton, but then its in my mind, that the app is running in background...isnt that bad at android-OS-structure, but its a bad feeling to me...

yes that's true. i was reading over your original post again and the first time through i must have overread the part where you named sms and the browser as examples. you are right, in that case, it does not work very well. an alternative way is to hold the home button, then press task manager and kill the app instantly. but that takes even longer. i guess your best option is to actually let it run in the background, if you want to get out of it fast.

I suspected this may be the case, really hope it isn't but I understand the Android security model needs to enforce a certain level of isolation for each app in the VM I'll do some further reading of the documentation to find out for sure, since a simple non-root APK providing this functionality for users would be very welcome.
I'm too used to other less-secure API's (Win32) in which any app could basically do whatever it wanted to other apps and the OS; I guess thats why virus authors love Windows so much

yeah just for anyone not totally in the know, there is a difference in android between pressing the BACK button and HOME button to leave an app. using the back button to leave an app and go back to the home screen basically "kills" the app. it puts it in a state where it can readily be killed by the OS in an instant.
when just pressing HOME to leave an app, the app is technically backgrounded. the OS will keep it around longer or in a different fashion.
so backing out of apps with the back button is always the way to "exit" any app.

What is new with Home Button Lag ?!

Hi ,
Any news regarding the home button lag ?
I don't mean the wake up lag, which is annoying too but it's hardware issue.
I mean the home button lag, which means any program I running, and pressing the home button, it takes something like 1-2 seconds to return to home screen !!
I know this issue has been raised 1000 times (!!!) and that is the exact reason I am talking about this, it's annoying so many people, so how could it happen that it hasn't been resolved yet ?!
This is 100% software issue , CM7 for example doesn't have that. But I don't want to use CM7 ....

I also have it and it drives me crazy.

Disable voice2go and the other parts of the samsung TTS thing, use titanium backup or something, you will need to be rooted.
As when you press the home button it is waiting to see if you are going to double press it to activate the voice control.

Did that, it doesn't help mate.

Oliwe has figured out a solution that requires some dev expertise:
http://forum.xda-developers.com/showthread.php?t=1227479&highlight=home+lag
I tried it myself and failed, but I'm sure ROM cookers will start implementing this ASAP.

Still a non issue

UI Lag?

I've noticed that after pressing the home button and swiping between menues there is a VERY SMALL, yet noticeable lag. Sometimes the clock/weather widget reloads. It was like this out of the box the first day. Then you start swiping between homescreens and its gone and everything is smooth as butter literally.
I saw this in one of the review videos too. Hopefully a software update addresses this. Somewhat annoying as the phone has 2GB of memory.

Same here... Swiping the home screen is smooth but returning to the home screen via the home button causes a 1 second delay...
I have also noticed the clock / weather widget refreshes when returning to home screen from apps at times...
Overall it's not big deal and I am sure it will be fixed in the next update...

yes~!!! this is one of the annoying parts of this phone.
it isn't performance related either. in nova launcher i have it set that pressing home when at the default screen brings up the app drawer. doing so causes the same fraction-of-a-second delay. but pressing the actual app drawer button on the screen is immediate. something in the Android software is causing this delay between button-push and action.

Thought it was just me.
I'm going to root it and flash ultimatum. Hopefully it gets rid of it.

Thanks guys. Glad to see its not just my phone. Its by no means bad, just annoying. The home button needs to be more responsive. Hopefully in a software update. If this is all we have to worry about then I'm good.

Yea. Same goes for me, tried both apex and nova just to test if the lag depends on the launcher. I'm on apex now though, a bit less laggy than nova.

Nova with fancy widgets (sense style clock) and voice disabled not really seeing any lag.

There is a setting you can turn off to fix this home button delay actually.
What you do is
1. Go to apps
2. Find "S-Voice" and open it
3. Hit settings button
4. In settings there is a option for "Launch S Voice" near the top of the settings.
5. Click the box to stop it from launching S-Voice when you hit the home button.
6. Now the home button works very quickly, no more second delay.

thank you
you are awesome.

The delay is there because if you double tap the home button it brings up SVoice, so it gives a small Window waiting for the second press before going to the home screen.

There is still a lag after unchecking the S Voice launch option. I hope this can be fixed.

I wonder if the Exynos version has any noticeable lag or delay?

I actually completely disabled S-Voice and see no lag
Menu > Settings > Application Manager > All > S-Voice > Disable

If I wanted to be a "talking to your cell phone like its a person" douche I would have bought an iPhone. Keep your dignity and just type in whatever you're trying to do, it will probably take less time then getting the voice recognition to get it right
TW is pretty weak for a launcher though.. I put on my ol' trusty ADW launcher and no lag to be seen there..

The one and only thing I ever use android's voice recognition for -- and you don't even need S-Voice for this -- is setting alarms, because it's quicker than doing it manually and very accurate.
e.g.: "set alarm forty five minutes"

lol, didn't yall watch any reviews on Youtube? They stated there's a slight delay because it's waiting for a second press for S-Voice. I thought everyone knew that.

Not when pressing the home. When swiping through home screens. There is a slight delay. Its Ever so noticeable. More so when having a few widgets on the home screen.

Yep. It's only brief, then everything is smooth is butter.

Well, I have 3 home screens so I don't really care. I had 2 on my SGS2.

Touchscreen and Typing Bug

This just started happening today....when I start typing in any app (falcon pro, whatsapp, txt or email), after the 1st couple of letters it goes right back to the home screen and I have to go back to the app and continue typing.
Is this happening to anyone?
Its getting annoying real quickly.
I have rebooted and changed to the google keyboard and it still happens.
Help!!

Happens to me sometimes when i type fast......but i found out that its my fingers hitting the home button when i press space. Your phone is fine. You just need to get adjusted to the keyboard. You might want to download and use Googles keyboard instead of LGs, if you havent alrrady done so. Im more familiar with Googles layout....perhaps you are as well
Edit: sorry, didnt notice that you are using googles keyboard already
Try this....while you type, follow your fingers instead of looking at the screen....im 90% sure you are hitting the home button like i do

yeah i hit the home button all the time instead of space lol oops

Google application, long press home

So on my note 4 long pressing the home button opened up the Google application. Now with the v20 though it opens up an overlay. However, about half the time or more that I long press the home button, the overlay doesn't open or it immediately closes or when I try searching for something it randomly deletes everything I've typed and closes my keyboard. Does anyone else have this issue or know how to fix it?

The overlay was a change introduced in Android 6 and later called Google now on tap. As far as the issues you speak of I can't say that I have any problems with the way the app works at all. Perhaps it could be attributed to use error. Could it be you don't fully know how now in tap is supposed to work and what makes it different than the older push to open Google now shortcut on Android before Android 6?
I suggest a quick "Google" for Google now on tap so that you understand what has changed and how it exactly is supposed to work.

@EROMITLAB No, I'm fully aware of how it works and how to use it. I was also aware of why the overlay was changed. I'm not attempting to use the now on tap portion, nine times out of ten I'm only ever trying to quickly get to Google and perform a basic search and the white square will appear around the end of the screen as if it's going to open or when I go to search it will just close. Yes, definitely user error. How could I ever be so foolish as to not know how to use Google. Clearly I'm the reason the app won't load or even occasionally pops up with a force close.

No need to mock me I was honestly just trying to help. There are occasional post from folks in here who aren't as tech savvy as the majority of people in these forums. Sorry you felt disrespected or insulted.
Anyway no I don't have these issues at all with the V20. Sorry about your luck.

Hmm, just tried it out and it works like it should for me. On a Tmo V20.

I have the same problem. It's definitely not just you! Although, mine never force closes and always opens the overlay search box, it ALWAYS closes out my search after typing a few characters, and then I have to start again. Frustrating.

Hey, I just tried something and it's an acceptable workaround for me. Hold down the home key until the overlay search box appears and wait a few seconds to let it calm down. Then tap the menu button at the bottom right corner of the screen and choose Settings. Now toggle off the first menu item to disable Now On Tap.
Once that's done, long-pressing the home key will launch the standard Google application, and you can start typing immediately without getting kicked out.

I get the same issue when trying to type into the Google Now on Tap. I'll begin typing then after a few seconds the keyboard will disappear along with what I typed in. I've seen one person say that it was Nova Launcher and once they switched it, the issue was gone. That did not work for me.

Dude, just do what I suggested in the post directly above yours. Turn off Now On Tap and you're all good.
