[Q] Home and search softkeys stop working

I have a stock phone, updated with the OTA update. I have this problem where the Home and Search softkeys will stop working all of a sudden. When you press them, they seem to flash so I dont believe this is hardware. Also when I restart the phone, the problem goes away, at least for a little while. When this is happening, to get to the homescreen I basically have to use the back soft key to go all the way back. I thought that maybe this was due to some updates I did so I uninstalled NoLed and TaskSwitcher and I was fine for a few days but it just happened again. Has anyone else experienced this? Thanks, this is my first Android.

If I were, I'd exchange the phone. Sounds like the sensor for those buttons is defective.

It's not the sensor as a reboot will immediately fix this issue. Some say that doing a reset will fix it. Thinking about trying that.

Sprint LG G2 - Lock screen not activating, Home soft key not working...

This just started occuring this afternoon before and after I installed the latest ZVA firmware:
1. The "Home" soft button responds to my touch - as in I get the visual and haptic feedback as if I've touched the soft button but it refuses to actually DO anything. I can hit the Home button on any screen and any app and it takes me nowhere.
2. The Lock screen is no longer activating - as in I let the screen hit the timeout and let it set for a few minutes. If I try to "knock" on or use the power button, it opens right back up where I left it with no Lock screen.
I hope this makes sense. I'm really stumped here. Like I said, it just started happening this afternoon and I figured that it was some weirdness to due w/ the pending OTA update. After installing the OTA update, the problems persist.
I'd rather not do a factory reset, but I will if I must

same here, my tmobile d801 updated to stock kitkat via OTA, i was able to keep root but I was encountering "BLUETOOTH" battery drain even when bluetooth was not enabled so i did a factory reset and got a black screen with white error message
"boot certificate error"
after that the phone reboots but i have the same problems
1. Home button does not do anything but does respond to touch.
2. Notifications are not working anymore.
3. Lockscreen is not working even when enabled in settings
4. I cannot factory wipe, from settings or using volume down + power button.
5. Settings are in a list view instead of tabbed.

Bringing this old post up as I just now encountered this on my AT&T LG G2. It occurred when I was using Google Maps which then crashed and caused everything to freeze. Upon reboot, I get the exact same issues as stated above. What was the outcome for you guys? Did you end up doing a hard reset?
Everything appears to be functioning with the exception of above. I'm suspecting a software issue with the home launcher as the soft keys are responsive but the Home one. The Notification Bar lags when trying to drag it down, but none of the notifications are functioning. I also noticed a significant amount of lag. Prior to the "crash" my phone was flawless with no lag for the past 10 months. I absolutely have no clue what just happened...

Stuck on black screen (5.0 w/ hybrid modem)

Hi guys,
I flashed 5.0 over the weekend and the .33/84 hybrid modem to enable LTE. I also made Google Search my home launcher.
The issue is screen becomes black, just showing the status bar and navigation bar. The system bar and navigation buttons are responsive and i can access the notification drawer/system panel but tapping on them does not remove the black screen. The only way to fix it appears to be a reboot. It started out intermittently but now it's happening within just a few minutes of each reboot.
I've tried clearing cache partition from (stock) recovery but it doesn't seem to have helped.
Thanks in advance!

The pattern I've started to notice is that it happens when I get some sort of popup. For instance I use handcent for SMS and half the timeI get a text I end up getting the black screen. I just got a Facebook message and I'd imagine the little circle that shows up on the screen caused it this time.

I've gotten the black screen a couple of times over the last few days since installing 5.0 using the factory image. All that can be seen are the navigation and status bars and there is no touch screen response at all, only a reboot solves the issue. I never saw this happen at all before upgrading.

Have you tried using the .33/1.04 Hybrid modems? I have been using them since they released and never had this happen when using Messenger or Textra and getting pop-ups.

I haven't tried that modem. I've even returned back to the stock modem that came with the 5.0 image and am still having the same issue. Do you have a link to the .33/1.04 modem? Thanks

Honestly, if it does that with the stock modems, I would reflash the factory images clean, then use this one: http://forum.xda-developers.com/nexus-4/general/4-4-3-nexus-4-lte-lte-tethering-hotspot-t2416822

Just reflashed 5.0 and seems to be going okay so far (haven't seen the issue). Is it okay to just flash the hybrid modem without using the rest of the LTE enabler? I don't mind having to manually select the network after every reboot...

Yes, you can certainly do that if you wish.

Crap. Still having this issue. Anyone else?

Yes, this is still happening and I'm just using the stock modem(not hybrid). I've also reflashed the factory image 3 times. I get the black screen at least once a day, sometimes only icons or folders or widgets disappear.

Im struggling with the same problem.
Stock 5.0 google image / With some other kernels / Even tried recent Rastapop. - Wiped System/cache/data, didnt help.
Also i have problem with connecting phones storage via USB. I can Barely access internal storage thru computer.

possible solution
Since I deactivated the app called "Tasker" my phone works just fine again... Plus that I deinstalled two other apps that required superuser rights.
Hope that helps others.

Still having this issue, even on 5.0.1 any ideas?

Okay I *think* I may have figured out the problem. I think it has to do with apps that try to enable/disable the lockscreen. I had Settings Profiles set to disable/enable my lockscreen based on location. I've just removed that setting and so far it looks like the problem may be gone.

I don't think this is a modem issue. If you Google "lollipop black screen" you'll get quite a few hits. I remember reading something last week about this bug affecting lollipop builds.
I'd say stick with the modem that makes you happy :good:

Stock modem and rooted on 5.0.1 and I have the same issue. In my case it is not random and only occurs specifically when I dial the phone from the Avast Mobile Security website (There is a test mode to call the phone). Not sure how they dial into the phone but the screen goes black with only the notification bar on top and navigation buttons on bottom. The notification bar works but the navigation buttons do nothing until the incoming phone call ends, at which time everything returns back to normal. Regular incoming phone calls do not exhibit this behavior. Now if I access the phone from the Avast website by entering a text message instead of a phone call, a pop-up appears on my phone along with my message, but it does not cause the screen to go black.

Hum, sounds like it could be what I am experiencing...possibly a pop-up interfering with the phone call screen.
EDIT: (SOLVED). After contacting Avast via their forum, it turns out that they are doing this on purpose. It is supposed to prevent a thief from ending the call, although that is as simple as restarting the device.

Lockscreen not working, also "System UI isn't responding" and Settings app FC

Lockscreen not working, also "System UI isn't responding" and Settings app FC
Hey there. I hope this hasn't been addressed already, I wasn't able to find a thread that would help me.
I'm running stock 6.0, no root. A month ago, one day my MXP lockscreen started having some pretty terrible problems; it wouldn't respond, basically. Pulling down would end up with a frozen lock image, then I'd need to press the power button to switch it off, then press it again to get to the proper lockscreen, and that wouldn't work either. After trying about 200 times I would be able to unlock it, then I'd start having problems with the notification bar (wouldn't work/wouldn't get to quick toggles). I tried rebooting several times, but after a few seconds on the issue would start again. Somehow after a while it seemed to start working properly on its own.
Today the same thing is happening. Only this time it's persisting after four hours. I guessed I would just disable the lockscreen altogether, and that seemed to work for about ten minutes. Now I get the notification bar issue, random system UI not responding messages, app switcher issues, a sometimes-not-working home soft button, and when I try to set the lockscreen again it asks for my pin (which I'm not sure it should, being that I disabled the lock); when I type it in the security app crashes.
The issue persists on safe mode as well.
Any ideas? Thanks a lot in advance

Factory reset?

Time for a custom ROM, may I suggest TruePure 2.9

OP isn't rooted, so suggesting a new ROM is not going to help. If this is happening even in safe mode, it isn't app related. Sounds like a hardware issue. Contact Motorola (or Lenovo).

Issues with my device crashing

I purchased a Mi 9t a few days ago, and I'm experiencing a recurring issue that I can't seem to solve.
From time to time, the UI will simply crash. I can still see my apps but I can't open them, and the notification bar on top of the display just disappears. I can't access anything and my only solution is to reboot. Sometimes I'll have to reboot multiple times a day, which gets old quite quickly.
Most of the time it seems the issue occurs when I'm trying to go to the home screen, whether with gestures or with the home button.
- At first I thought it was a conflict between the gestures in Nova launcher and the gestures of the phone. Turning them off in Nova didn't fix it, so I tried to disable the phone ones and started using the navigation bar, but it didn't fix the issue either.
- I did clean Nova launcher's cache along with the system launcher's one, didn't fix anything.
- I tried to do a full factory reset, it didn't fix anything either.
- I tried to disable the search bar, didn't fix it.
- I tried using another launcher, didn't work.
- Using the system launcher didn't work.
I'll add that my phone and apps are all up to date.
I didn't find anything helpful on the internet, and now I'm out of ideas. Is it software, or could it be hardware ? I can still send the phone back and get a replacement, should I ?
Thanks for your input !

Hi there,
When you did a full factory reset did you start from scratch or did you import your backup?
If you did it with your backup once you were setting up your phone again, it may be some app that you have recently installed.
If you did factory reset (without restoring your backup) and still experience the same issue it could be Software/hardware issue (software being more likely) and yes you should send your phone for repair or get a replacement phone.
But before you do I would advise you to wait until another software update / Security patch is out and see if that resolves the issue for you if it does it was software issue if it does not it is a hardware issue.
Hope this helps

Thank you for taking the time to write an answer, I appreciate it !
Because of a delivery error I received a second device, so I decided to switch and send back the first one. I also suspected that it was more likely to be software rather than hardware, but thought I'd do it just in case. So far the issue happened once on the new device.
You raise a good point I hadn't thought about. I transferred the data from my old phone to the new one, at first. When I did a factory reset I entirely wiped the data on the phone, however I had backed up my data with Google and the Mi cloud, which I restored.
I think I'll try doing an entirely clean install if the issue persists. Thanks you !
