[Q] Back Button Problem - Droid Ultra Q&A, Help & Troubleshooting

For several days now I've been having this problem appear in different apps. First, it happened on the Facebook app, then on an app called Goal, and most recently on the Textra (SMS Alternative). What basically happens is when I press on the back button (be it the capacitive button on the bottom of the screen or the button in the app that appears on top), the screen just refreshes. I'm not talking about a refresh like on an internet browser, but more like it redraws the screen really quickly. I basically get stuck in a specific screen. What's worse is that even if I do somehow get out of the screen,the next time I come back to the app (say I switched apps for a minute), I will be back in that same screen.
No matter what I do, it's almost impossible to get rid of the screen. I tried clearing the running apps, and even if I start it over again it will go back to that same screen. The only thing that has so far worked has been either clearing data for the app, which can be troublesome especially if it's an app that requires some sort of a setup, I end up having to do that all over again. Or in some cases, I reboot the system.
I have recently installed a memory booster software, and this only occurred to me know that I'm writing this message. I will uninstall it to see that was what was causing the problem, but if it isn't, does anyone have any idea what it couuld be?
I'm running NOVA Prime 3.0.2 on the Ultra MAXX.

Have you booted into Safe Mode to see whether this same behavior occurs?

How do I go about doing that? I'm not rooted.

This can be done on stock unrooted. Power off, but long press "Power off" to see the option to boot into safe mode.

[Q] Apps launching slow

I am on CleanRom 3.0 right now, fresh install. Now, for the problem. Today while sitting in class I took my phone out to see it was booted into safe mode. So I rebooted it back, and noticed a lot of my downloaded apps were launching 10-25 seconds after I clicked to open them. So, I rebooted again. That didn't work. I cleared cache and dalvik cache. That didn't work. So, I dirty flashed CleanRom 3.0, which still didn't work. After driving and listening to spotify in my car, the apps launched completely fine, and still are. Does anyone know why this is happening? By the way, this happened on my rooted stock rom, that's why I switched roms. I don't know if this could cause any issues, but I do use Directory Bind.
Have you checked if power saver is on?
Another possibility could be a lot of applications running the background and just slowing your phone down.
Check your task manager by holding the home button for about 2-3 seconds.
Yea, power saving is off. And there isn't any apps running in the background when it's ran slow. Most stock apps will launch fast (settings, phone, clock), but downloaded ones won't (I funny, handcent sms). I seriously can't figure out what the issue is. I've even tried messing around with set cpu, but that didn't help.

[Q] Tapping a recent app opens a different program

At random times when I tap the thumbnail for recent app the wrong app will open up. Has anyone else had this problem and found a solution?
I'm running the factory ROM and I'm not rooted. I recently did a factory reset and the problem still occurs.
I don't have a solution, but i have also noticed that happening. At first i thought it was my imagination and that i was just absent mindedly hitting the wrong app.

I can confirm the issue. Fortunately it doesn't occur frequently, but it must definitively due to some bug in the touchwiz.
Well, it does happen quite frequently on my device; like 4-5 times a day. This is somewhat frustrating.
It mainly occurs when I frantically switch between apps, hence at the worst possible times... Any help?
(For referencing, as those keywords did not popup in my googling: app switcher, wrong app)
If you wait 1-2 seconds after hitting the switch task button before selecting a task, the bug does not exhibit itself.
Couldn't find any reference about this problem on Google either.
Would love to see it fixed, it's a PITA!
My solution is to press about half a second before releasing, if you press long enough you get up a menu though so somewhere before the app gets a blue frame around to the menu pops up.
Also, I've noticed that it doesn't accure as frequently if at all when using the pen.. But maybe that's just mine, and I don't really like using the pen for such "browsing" so it's not really a solution.

Black screen after 5.0 update

I received OTA yesterday and so far found one bug. There is a black screen comes up randomly. Top and bottom bars are visible but I can't do anything to get out of it. The only thing that works is restart. I can't pinpoint the app that might be causing it. It happened while updating apps or using Firefox. Anybody else having this issue?

Did you wipe your cash after updating? I had experienced several bags after the OTA update too, but i cleaned cash from the recovery mode and now everything works just fine.
Did wiped cache from recovery mode yesterday and it was OK. Today the black screen issue is back. It's quite annoying having to restart.

Hi there, I am currently having the same bug on my Nexus 4 device.
It appears the same way, with the Softbuttons visibile and the top bar still able to be pulled down. Plus that there is no option if I restart to get my SIM card recognized. Pretty annoying when you have an encrypted nexus device and have to wait 2 minutes to restart with a 40% chance of NOT getting the black screen again.
My assumption is that it has something to do with the kernel. Any suggestions/confirmations?
Best regards

Same problem here... black screen with only softbuttons visible and notification bar working.
I think the problem occurs when an application is in full screen mode (no softbuttons visible) and you do a little swipe to make the softbuttons appear... It must be something with the way the softbuttons overlap the screen, I think.
Any help?
I am also seeing this problem on my Nexus 5 which I flashed the factory image with full wipe. I have had it when exiting apps and also when an app is open it can just happen. If i swipe up from the bottom sometime I get a flash of the screen during the animation so it is as if a layer is over the screen. I hope this is fixed as it is random, this morning it happened and after a reboot i logged in and it happened before I opened an app, reboot, then happened again a few mins later, but after a 3rd reboot has been ok???
For everyone that is experiencing this problem... do you have Tasker installed?
I disabled tasker and since then I don't have this problem... so far.
Still happening once in awhile and I do have Tasker.

It happens to me. My current theory is that, in my case, it may have to do with a profile manager I use which turns the lock screen pattern lock on and off depending on where I am.

I also have tasker, don't want to disable it as I find it too useful, can you keep us all informed if it cures the issue.

I also find tasker very useful.. but I think it was causing the problem. No more black screens since then.
To try to narrow it down even further... do you have a profile to enable/disable the lockscreen in certain situations?

I do use tasker to disable the lock screen, I wish that the smart lock would completley disable the lock screen, and not just the secure section. I will take all the lock screen options out of my tasks and reboot, will test for a few days.
I tested over the weekend and had no black screens with all tasker/secure settings lock screen disables turned off, I left all other actions on , so I think you are correct. actualy got on OK using the smart unlock, although when in my house sometimes GPS is lost so it will relock, but not a real issue. Thanks for the heads up

[Q] Slow Home Behavior

Hello everyone!
Let me start off by saying that i'm actually using an unrooted, officially update nexus 5, updated to the latest 5.0.1
I have no problem whatsoever, battery really seem to have improved, but lately i've been getting a strange behavior
After a period of use (it goes from a couple of days to a whole week) the phone oddly slows down when i press the middle button, to return back to the homescreen.
For example, if I'm using the facebook app, and watch a couple of videos along with opening a few external links, when i press the home button, the whole home "loads" from start. I mean, i literally see nothing for a second, then it slowly loads widgets and icons. After it's been loaded, everything works flawlessly again, but if i open facebook again, use it for a while and press the home screen, it loads again.
Mind that i have no custom drawer (i tried Themer, it gives me the same error, it says "loading homescreen" when the problem appears) but the problem is still there with the stock homescreen. I tried force-closing the apps i used, thinking about a memory issue, but to no avail. I have to turn off and turn on the device, and everything works wonders again.
Is there any app that could help me with this issue? I'd like to understand why it's doing this and which app is slowing down my phone.

I am not Sure whether this is 100% sure, But have heard that there is a memory leak issue in lollipop. Which might be the reason of ur problem. And the oly way get enough memory is to restart. But again, I am not Sure whether the above information is correct though.

I've heard that too, but it's strange that it has appeared only now. I haven't had this kind of issue ever since i updated it.
The FB app is just real buggy. My personal theory is whatever that app does exposes the Lollipop memory leak.

Yep i know about that, the FB app is just horrible script-wise. Nevertheless, i've never had THIS problem. And even if i forceclose it, it doesn't solve the problem anyway.

Pressing the back button to exit an app sometimes takes me to other random apps

I've been having this problem for a long time, accross different devices and OS's.
The thing is that, sometimes, if I exit an app using the back button, instead of going to the homescreen I'm sent to other apps that had been previously open (but also closed). Pressing the back button again in whatever app it opened, would often take me to other apps until I finally get the homescreen.
This doesn't happen all the time, but it is quite often and annoying.
Any Idea what can this be about and how to fix it?
I'm using Nova Launcher (prime), which I suspect may have something to do with it.
Thanks in advance.

This happens to me, too, on occasion. It seems that it always happens if I launch an app directly from the app I'm currently using, and with certain apps, every once in a while, I get what you're getting. My solution has been to use the app ATK, or Advanced Task Killer. It's simple to use - just kill apps when you're done using them - and it also drastically lengthens my battery life. I'd highly recomend it.
