[Q] Random app pops up after back-button exit - Nexus 5 Q&A, Help & Troubleshooting

Hi,
Searched the internet but could only find one other writing about the exact same issue that I have.
Has any of you experienced the same? I happens quite often unfortunately...
Quote from this Google forum:
I have a habit of using "Back" button to "exit" from Android applications back to the launcher. Recently, I started noticing a rather peculiar and intermittent behavior associated with "Back" button. Consider the following scenario:
I launch my Out of Milk app using a icon on my launcher screen. The app starts successfully. I do what I wanted to do. And then I hit the "Back" button in order to return back to the launcher screen. The Out of Milk GUI disappears, but it is immediately replaced with Google Earth app splash screen. It is displayed for a very short time (a split second). Then it disappears and I finally return to the launcher screen.
Some other time I launch RealCalc app, do what I wanted to do, and hit the "Back" button. For a split second I get thrown to Contacts app for and only then I return to the launcher.
This seems to happen with all apps. Sometimes, when I hit the "Back" button I even get to see glimpses of two apps instead of one, in sequence, each for the very same short period of time. This behavior is very intermittent. In many cases the "Back" button works as it is supposed to, i.e. it returns me to the launcher screen immediately.
So, what is causing this strange "flashback" behavior?

Do you have any launcher set to default?

Happens to me too, but rarely.
I have set Nova Launcher to default, how is this related?

I use nova too, but don't have any other launchers installed

Yeah, even I face this thing at times. I can confirm this happens on Nova Prime as well as Aviate.

well, if you don't have any launcher set to default, you can kill it and when you click on back button it goes to random app, but you have the default launcher set, so this is not the problem in your case.
P.S.: I also have Nova Launcher and don't have this problem, so the problem must be somewhere else.

I'm using the default launcher.
It's very random to me, which app is popping up. Mostly it's an app that I've been using within the previous couple of hours...

That's really weird. Do you use any custom ROM/kernel? Do you have Xposed Framework installed? Is your phone rooted?

same thing has been happening to me for a while on probably 5 different roms and I always use the GEL launcher. I cannot for the life of me figure out why it does it.

Stock ROM with Franco kernel. But I think it also happened on Faux kernel, but not 100% sure.
I also just disabled Xposed Framework to be able to run on ART, which didn't change it.

It just don't make sense to me. I am also using Franco kernel, but not with stock ROM. I also have GEL and Nova Launcher installed. I have run out of ideas.

same here, quite annoying, 4.4.2 stock and franco r34

I find this happens when a [bad] app crashes. I can't remember which app I had problems with but until I uninstalled it every time I used the back button to leave it I'd wind up in another app, usually one I had not used in a while.

happened here too... stock launcher, stock kernel, gravity box installed, rooted... about the only changes i've made.

Just a kitkat glitch probably

This same issue happens to me as well, not too often but it does occur. The apps that mostly come up for me are the dialer and gmail. Im running SlimKat 4.4.2 Build 3.6 with Nova Prime set as the default launcher and I actually started experiencing it after seeing several people who brought it up in the SlimKat thread. However, from what all i have read, seen, and been told about it though, it has been happening to people on all different KitKat roms both custom and stock and not just any one thing in particular. Like another person said, i too believe it is just a KitKat bug in general and not something specific as to any one single thing that could be causing it. I would guess that it will be fixed eventually being that many people have been experiencing it and not just a few.

I'm also having this issue. Stock rom/kernel and rooted. Caught it on screen record. Excuse the background noise. Didn't realise it was recording sound. http://youtu.be/sOxzuiFv3xQ

Glad I'm not the only one experiencing this problem. Also sometimes when I'm exiting to the homescreen my icons and widgets take a split second to appear.
The same thing happened on my Skyrocket running 4.4.2 before it kicked the bucket. Figured it was due to running a custom rom but now it's happening on my mostly stock N5.

This is unrelated, it is just redrawing your homescreen.
Haven't had this issue. Are you guys tapping the back button quickly and repeatedly?

LauncherPro not staying in memory

Hi all, just got a TB and rooted it yesterday. It was one of the first things I did when I got my phone, so I can't say that this wasn't an issue beforehand, but it seems like LauncherPro isn't staying in memory. Every now and then, when I press the home screen, it will ask me whether to use HTC Sense or LauncherPro. This will keep occuring at random, even after I've checked to use LauncherPro by default. Is anyone else having this problem? Know a quick fix?
Nobody else experiencing this?
there's an option in launcherpro's general settings 'keep in memory'. have you tried that yet? are you using some sort of app-killer (like advanced task manager or ES)? is launcherpro ignored in that?
Sent from my MB525 using XDA App
Ah, sorry, should have clarified. Yes, I have the keep in memory already checked and I am not using any sort of app killer unless there is a stock app killer that I don't know about.
ok, then. in the phone's settings menu, go to applications/manage applications, find launcherpro. is it selected to launch by default?
Sent from my MB525 using XDA App
No defaults set, which is why I assume the settings aren't sticking. Should I just force stop, clear data, uninstall, reinstall to see if that works? Or do you know a nifty way to set it to the default launcher.

you could do what I did, and use Titanium to remove HTC Sense from the phone. No point in having it if your going to use a different launcher.
Haven't checked yet, but is removing HTC Sense one of the safe removable apps? Were you having the same issues as I was or did you just remove it because you didn't use it?
i don't recommend uninstalling sense. i know, launcherpro is good and all, but it's still a third party software, and if something goes wrong, you're left with no launcher, and that kind of sucks... and no, i don't know any way to make it default (other that choosing from the list when it pops up). but reinstalling might help!

i am running das bamf and removed every bit of sense I could get my hands on immediatly as I like what they did with the rom but hate sense. I also installed launcher pro right away and deleted sense.
I have never had launcher pro end up at a point where I couldn't use it anyone. I did this for 2 months on my evo 4g, and will continue to do so.
Just stuck to the tried and true method of clearing data. LauncherPro seems to be sticking now. Thanks for all the replies!
Ah, spoke a little bit too soon. Doesn't seem to be sticking any longer. When I rooted, the process went very smoothly and all root apps that I have run with no problems.
I'm just wondering if there's any way that rooting may have affected LP since no other users seem to be having this problem.
Bumping this.

I have had this very same problem since day 1 with my T-Bolt, and it's driving me crazy. I have not rooted yet, so rooting has nothing to do with it... just so you know...
Like with your's, I get that nasty launcher selection popup randomly; and if I exit from any streaming app or music app, it pops up EVERYsingle time the HOME key is pressed.
It also happens with ADW in exactly the same way as LauncherPro, so I would bet it happens with any launcher that is not Sense.
What have I done to fix it?
1. I have uninstalled / re-installed LauncherPro (and ADW), with no luck.
2. Just in case it was a conflict of Google restoring what I had on my Incredible to my T-Bolt, I uninstalled every uninstallable app I could, and then waited over night for Google to do it's backup ( to create a blank backup), and then did a hard reset the next morning, with no luck.
3. In Settings>Privacy, I unchecked the "Back Up My Settings" box and discovered that a window pops up that says, "Are you sure you want to stop backing up your settings and application data AND ERASE ALL COPIES ON GOOGLE SERVERS?" When I saw that, I saw no need to do the overnight thing and did this repeatedly with hard resets - all this WITH NO LUCK.
4. As a last resort, I took my T-Bolt back to Best Buy (thinking that maybe something went wrong in the provisioning process during activation), and they reactivated my T-Bolt with a new SIM card. Once again, NO LUCK.
I don't know what the heck is going on with it. Maybe it's a rogue app that's conflicting with the T-Bolt. I don't know. What I do know is that there is no problem if I'm using Sense, but I don't like Sense and refuse to use it, so I'm stuck with that darned popup.
I thought that rooting and using a different ROM altogether would get rid of the problem. Have you tried flashing a different ROM?
We have got to find out what's causing this, or at least a good workaround.

Thanks for the reply. Puts my mind at ease knowing that I'm not the only one with the issue and also helps to know that you're experiencing this on an unrooted phone. I have not tried flashing any custom ROMs yet, so perhaps the people who have flashed a ROM can report back on whether LP is acting up on their phones.
I hope it's as simple as LP needing to be updated for TB.
Had this same problem myself... Download an app called HomeSmack from the market. It is free and allows you to switch between Sense and launcherpro easily. Have not had the issue since. Also I can easily switch back to my sense home screen and vice verse without a set-up every time.
Hope this helps

Yeah, I forgot to mention that neat little app - Homesmack. I like it. It's the only way I was able to actually get to LauncherPro from Sense. Without it, for me LauncherPro was simply a *download* that I could not access.
However, it did nothing to keep LauncherPro in memory. It does allow you to clear data from Sense and actually kill it momentarily; but once you get back into LauncherPro (or ADW), the problem simply repeats itself on my T-Bolt.

If I have time, I'm gonna root my T-Bolt this weekend. And then I will immediately flash a ROM - ANY ROM - to see if this works.
From what I'm gathering with regards to the T-Bolt... there are lots of bugs with this phone; however, not all T-Bolts share the same problems, and some are way more common than others. My T-Bolt is, for the most part, flawless; except for the launcher staying in memory. My wife has the headphone jack problem with hers... not everyone is experiencing that, but there are a batch of T-Bolts with faulty headphone jacks. Guess that's what we get for being early adopters. What the heck though, every other 4G phone that comes out will have flaws too. If people are expecting these phones to be fully *worked out*, they should wait and upgrade to 4G next year.
In the meantime, I've found that hitting the *back* key instead of the *home* key bypasses the launcher pop-up selector altogether. It can't be relied on completely because there are some apps you can't get out of without hitting the HOME key.
btw, my coworker has a tb and has this issue of the launcher pro constantly asking to be the default launcher. looks like if you hold the home button to switch between tasks, it clears the default launcher setting. try not using the hold home to multitask function to see if that stops this from happening.
I can verify this behaviour, and it 100% reproducible. It 'forgets' the default launcher with 2 actions:
- Pull down the status bar notification.
- Long press home to switch apps.
It doesn't happen otherwise. I use Wave Launcher, and it doesn't affect the default launcher.
This only started happening this weekend. I have to go through the apps I added recently.
I'm not rooted.
Using Zeam launcher.

Problem with ICS launcher

Hi guys!
I´ve just updated my TF101 to ICS and it´s really fast. But I have a problem with the laucher. Some times, when touch the home button to go to the homescreen, the laucher and all the icons desappear.
I can´t go to the apps that are open (with the multi-task button) but the launcher doesn´t appear.
The only solution I know is shuting down the Tf101 or closing the laucher app, but it is quite boring to do ir every 5 or 10 min.
Does it happen to anyone here?
Happens to me as well.

Same here... needs re-boot to recover...
I only had that if the option to kill tasks as u exit them was checked on. Its under developer options towards the bottom.
Edit: actually that's only the case on my phone. I have the option checked on my tablet and it works just fine.

same here but may be able to narrow it down.
I am having the same problem. The whole screen just displays the wallpaper and removes any icons or buttons. So I can pan sideways and can sometime know what I am clicking on by memory but all icons go until I reboot.
weird thing is.... I have done a factory reset. reloaded my apps and settings. Its all working fine until I pop the Gmail and Calendar widgets on the screen, then boom. Gone again.
At the moment I am running without any widgets and I have not had a repeat. Do any of you clever clogs have any ideas on this one. Seems to be a small percentage of users with the issue.
Same...
I had the same problem however it seems to have stopped now. Perhaps as a result of my app purge that i did the other day.
Anyway for those still having this problem i suggest you use the notification bar to access the settings then from there you can go to the Launcher under apps and do a force close. after a bit it will reopen again with all screen icons and widgets back.
Guys I think this is the same issue, it happens on my tf.
http://forum.xda-developers.com/showthread.php?t=1519943
yep
Happens to me too,
I managed to fix it the latest time without rebooting, by going into settings, running apps and stopping the launcher and anything google. Next time this happen I will make a note of which killed process gives me my app icons back.
also its strange that even with the app icons gone, you can still click around the screen and open things, as if they were there.
same ...
same problem on my tf101
I fixed this by clearing the data for the Launcher in settings. Hasn't happened since but annoying as it meant rebuilding my homescreens :-(

you should try Nova Launcher, it looks and acts like the default launcher in ICS. But with a couple functions added. I havent had any troubles with it.
Just search it in the market. to get the widgets to work just move it to /system/app
I installed ICS on mine at the weekend. For a couple of days it reasonably stable, though certain apps lagged somewhat. Then it got much, much worse. There's a recurrent problem with the launcher. If you've gone away from it, such as to use an app, and then return, firstly the widgets and stacked/grouped app icons vanish, then all the rest of the icons vanish, and the three squares on the top right of the screen. The icons are still there, as it's possible to stab on the screen in the right place and launch the app that the invisible icon links to. All five screens of the launcher have vanished. The tablet still runs, as the live wallpaper still runs, and the recent apps are accessible.
Other problems include major freezes or lags. It's common to go to launch email or the web browser only to have to wait 20 seconds or so before anything happens. I've had to wait 5 minutes before now for Opera to launch. Eventually the tablet will freeze and I have to reboot it, but even then, apps take an age to launch, and regularly freeze. It's getting to the point of being totally unusable. It's taken many, many attempts to write this email as the app crashes of its own accord, and perish the thought that I copy and paste any text in, including the email address - it's enough to crash the email app.
My TF101 ran Android 3.2 perfectly fine, and very, very quickly. It was gloriously stable. I can't get more than 2 hours of use out of this without having to reboot; this afternoon I've been having to reboot every 10 minutes.
I've drawn Asus' attention to these problems via Twitter and Google+, and I know they've been told about it on Facebook, but there's been a wall of silence.

I had the problem with a disappearing launcher on ICS on 4 different launchers. Recently I removed a few widgets (NewsRepublic, Bacon Reader, and DroidWidget) and haven't had the problem reoccur. Maybe some widget incompatibility is to blame?

Could be. Mine's more stable (touch wood) since I got rid of both Beautiful Widgets widgets off my home screen.
Guys I´ve finally done a hard reset on my tf and all goes fine.

Same problem here with the stock ICS launcher. Using ADW Launcher EX without problems.
Some apps seems to be running super fast at times and then others super slow at times with ICS. Guess I'll do a Titanium backup and factory reset and see if that helps. ugh...

Home button keeps going to Recent apps!

So i have a Samsung Galaxy S3 with Paranoid Android 3.1 (March 1st build) and I also have Nova Launcher!
My home button used to always take me to the home screen! or main page! but randomly it keeps just opening recent apps! No matter what i do it just keeps opening recent apps i even went into nova launcher and assigned home to go to the home screen and still doesnt work! Any help or ideas!?
*EDIT
I just reset my phone and i think the problem seems to be Widget Locker which i used to replace my lockscreen, not 100% sure but it seems to be a bit buggy on 4.2 devices... it could even be some setting in it not 100% any help because this might happen again!?

That happened to me before even on CM10.1; I believe the feedback is sometimes unresponsively accurate.
But if you use Nova Launcher, you can manually take off "recent apps" and replace with "home". But, sometimes it thinks your quick press is a hold, haha. I just know reboot will quickly fix it... for now.

[Q] Black screen and wallpaper pop-in when exiting apps to the homescreen

This issue is a little hard to explain in greater detail than the title states. Happens quite a lot lately when closing an app. Basically after exiting to the homescreen via the home button I'm faced with a second or so of a black screen then the wallpaper and app icons just pop onscreen. Very annoying. Does anyone here know why this may be happening or what possibly might be causing it? I'm rooted pretty much stock with the Franco Kernel and xposed and only a few xposed modules.

Stock home-launcher? Or custom one? If so it might be custom home launcher issue,or maybe xposed module issue.
Is it a launcher redraw, like what happens when the phone is out of memory? Or is what you described something else?

I guess that sounds about right. Just now went in to Nova's advanced menu and an option was there for aggressive desktop which did mention about redraws and such. I checked it so I'll have to play around a bit to see if it'll make a difference. Thanks for mentioning it.
I've seen the same thing after playing a game on stock. Think it is the aggressive memory management in 4.4

Random app opens after unlocking

Sometimes when I unlock my phone, a random app opens. Anyone else have this issue?
I did on my Note 3 whenever on a TouchWiz rom, but so far not on the note 5. Never could figure out what caused it because it didn't happen at all when i was on CM.

I have this issue too. Sometimes the calendar app is open when I unlock the phone. I'm running Thrash Lite ROM with arter 4.3 kernel. I just thought it was me. Doesn't really bother me.
YES, multiple times per day. I think it started happening after the last update for me. It's really freaking annoying. I'm on stock, not rooted, and running Nova. It seems to always be an app that's on the home screen, even if my finger is nowhere near it.

Nah, I don't use Nova and have that issue. I'm on stock non rooted with Google Now launcher.
This happened to me while I was on my note 3. Someone pointed me to this app in the play store that does a scan to find out what apps play dirty and launch random ads. Maybe there is something that can catch the culprit launching the apps.
