Periodic blank desktop - Nexus 6 Q&A, Help & Troubleshooting

I am having an issue with my rooted, unlocked phone on 5.1.1. Every once in a while when in an app and pressing the home button to go back to the desktop I will instead get a blank screen. The navigation buttons are visible and respond when pressed (a gray background shows briefly when pressed) but don't do anything. I can pull down the notification shade but nothing happens when I press a notification. I can press the setting button but again nothing happens. This happened once while I was playing music and the music continued to play. I have to turn the phone off and then back on again to get it to work again. I thought it might be a Nova launcher problem so I went back to the default Google launcher but it still happens. As a last resort I reloaded the factory image, re-rooted and cleared all ther data to start from scratch but it is still happening. Has anyone seen this before or have any ideas what is causing this? It is driving me crazy.
Thanks,
John

It happens on my N6 a few times. Mostly when I had changed something.
For instance changing a language textfile of the nav.app Sygic. Or after adding custom Poi's.
Reboot solves the problem.
My idea is that it is related to caching or memory management.
Root N6, 5.1.1 LMY48i, FK r31, encrypted.
Disabled most g-apps;

Apps aren't opening...need help.

So starting today, after no changes being made. My apps won't open. I click on them and they bounce like I'm clicking on it but nothing happens. I did a full factory restore, they seem to work randomly then they stop working again until I reboot. After a few minutes, this happens again. The app menu button seems to work completely fine. It will bring up my app menu but the apps won't load. Sometimes when I click on them like 30 times they will finally open but other than this they won't. Also the home screen apps are having the same behavior. It seems like software but I don't know how it could be software related if I did a factory restore and it didn't help. Also when I hold the app button down like you would do to relocate it on the home screen, it acts like there is nothing there and opens up the menu that would come up if I held down on a black area of the screen to change the wallpaper or something. This is pretty terrible. Help? Thanks.
Update software then, Repair My phone with the Sony Update Service.

App update just disabled my phone??

I have an AT&T S5 running stock recovery with towelroot. Phone has been fine today, had 4 apps that required additional permissions for updates today so I ran them. I recall 2 were USAA and Tasker. Also FingerSecurity just got an update prior. After I accepted the additional permissions, I turned the screen off. I then heard it make the lock sound 3 times while the screen was off.
Currently I can turn the screen on or off, however the lock screen never comes up, just the home screen. Everything on the screen is unresponsive and the taskbar is gone. I've rebooted, wiped cache in recovery, it comes up the same way, bypassing the lock screen even though I have it secured with fingerprint. On the 3rd or 4th reboot, I did get a dialog saying systemui crashed. It keeps shifting the icons slightly like it's trying to add the taskbar but they shift about 10 times before finally stopping with no taskbar.
When I long press the power button, I have to be quick otherwise the dialog will disappear.
Is there anything I can do besides a factory reset?

[Q] T-mobile OTA update softbrick phone

Hello and thank you for attempting to help me. I have a Nexus 6 from T-mobile. My dentist appointment yesterday brought me clean teeth and a terrible phone problem. While I was there yesterday my phone decided to download the 5.1.1 update OTA. I pressed the okay button and it restarted. On boot up, I get a white window saying it is "optimizing apps x out of 138". It does that every time I boot it up. After that window is finished, I get a black backgrounded lock screen. On the lock screen in the usual place is the time. In the top left it says there is no sim card. In the bottom I get the normal call, unlock, camera buttons. I am able to drag down the top to show the notification information. As far as I know there are no settings changed from the factory Nexus 6 I recieved from T-mobile. Now I have attempted multiple tasks to try to access my phone but all have been in vain. Here is a list of what I have tried.
To unlock the phone normally. The result is a black screen, a little beep, a white window that says Google services have failed. After a second or two the white screen goes away and leaves a empty screen. I am still able to hold the power button to reveal the white power off window and it works. I can also hold down on the volume and the power button to create a screen shot. It even shows the whole minimization of the current screen and fall to the bottom like it would if the phone was working properly.
I tried to swipe the call button and all it does is give me a blank white screen with a blue notification bar at the top. I can once again power off or screen shot but nothing else.
I have not tried to swipe from camera yet.
I can drag down on the top notification bar to show the the notifications, quick setting changes (Wifi, data, airplane modes, brightness) and the setting button to go to the setting menu. I can turn the brightness up and down, and turn all the other things in the quick menu on and off but if I click anything (toogle them or slide the brightness) and put the notifications bar back up I get the black screen with the white google services has crashed window. I can power off and screen shot normally.
If i swipe down on the notification bar and press setting It crashes once again and gives the black screen and white window that says google services has crashed. I can power off and screen shot normally.
I tried holding volume down and the power button then went into recovery mode. Held power then press volume up to get to the next menu and then deleted the cache partition. It has no effect that I have noticed.
As stated above, I do not think I have usb debugging enabled, I assume my boot loader is locked. This phone has not been modded by me.
I do not want to factory reset if I do not have to due to the very important phones and numbers i have.
You didn't make a backup before updating ?

Unless there is a previous setting in place that I clicked to automatically update it when ever there is one available, I do not remember picking to update. It downloaded and asked me to reset. I assumed it was a small patch and not something that could screw up my phone. I could of though. But no I did not.

Well, I'd suggest a factory reset even though you are reluctant. Otherwise, bring it somewhere for repair. But chances are they're going to tell you to factory reset.

Reset itself overnight

Without doing anything myself, my Moto X 2014 has almost reset itself whilst I was asleep.
The first warning was no notifications, there's always an email or two, but then it wouldn't let me pull the quick settings down either. The phone wasnt using Smart Lock, in fact most system settings were reset. I figured something might be wrong with xposed (however, it's been running for months with no change, no updates to Android, xposed framework, or modules) so I updated all the modules and rebooted, still nothing. For some reason I went and switched to guest account, then switched back to my account and I'm now able to see notifications I missed and use phone almost normally. But my settings had reset and after setting swiftkey back up I see "Predictions not available. Check SD card." so typing is a pain.
My home button isn't working either, it flashes but doesn't do anything. The back and multitasking buttons work. Holding home button brings up Google Now on Tap, but it doesn't take me to home screen.
What could have happened? Is my storage knackered? Its not near full. Just to be clear, all my apps remained installed and logged in as far as I can tell. Only SwiftKey and the Home buttons remain as a problem.
Edit: Bluetooth devices also reset, wasn't connected to car stereo.
Edit 2: reinstalled swiftkey and predictions came back. Rebooted and they went again! Home button still not working.
Edit 3: Installed CatLog and when I press home it says: Not starting activity because user setup is in progress. So it thinks I'm trying to do first time setup? My accounts are already there (one of the settings that did remain).
Edit4: Ran
Code:
am start -n com.google.android.setupwizard/.SetupWizardTestActivity
as root (use su command) in terminal emulator and managed to complete setup... Home button works now and SwiftKey predictions seem to be working after a few reboots.
I hope that never happens again.

Home button notification makes me mad...

I have a problem, which appeared with first upgrade to 9.0.
It's still annoying me.
When I press home button (even iа it's fingerprint scanner) the notification is played. All the sounds setup for buttons is "off" in preferences. Reboot helps for 3-12 hours and it gets back again.
I've tried to reset the phone to factory defaults and reinstall back all my apps, but still this pain gets back 1-3 times a day.
Has anyone found a solution for this?
