[Q] Stuck after phone call - Nexus 4 Q&A, Help & Troubleshooting

I bought a Nexus4 a couple of weeks ago. I constantly got this issue, it will be stuck and not return to the normal screen even I keep pressing the power button. However, if the other side of the call hangs up quickly, it normally works fine. but if it is directed to a voice mail box, it will be stuck forever until I shutdown the phone.
Just wondering has anyone experienced the same issue ?

Have you put a screen protector on it?

It sounds like the proximity sensor on your phone is being blocked you might want to try not using your case and see if its make any difference

Installed Ballistic case on my Nexus S 4G, now the power button doesn't work.

I got a Ballistic SG case today and installed it on my phone. After a few hours of using it, the power button mysteriously stopped working. I was able to make it so the volume button unlocks it, but now I can't lock the phone and have to battery pull to turn it off (and it just turns back on, as if the power button is perma-pushed). Does anyone know what i can do about this? Does this seem like a hardware malfunction? Should I not use the case? Thanks for any help
Same case mine is fine.

Best case ever
Tried many cases in the past and the Ballistic Case is the best. Since i purchased it I never have thought about changing cases.

Problem unlocking N7?

Has anyone gotten this problem? Sometimes, when I try to unlock my Nexus 7, it doesn't actually unlock and turns off the screen. This happens several times before it finally does unlock. (Sometimes you have to activate Google Now before it will unlock) I would like to report this to Google but I am unsure how to do that by email. Just wondering if anyone else had this problem too. Thanks!
Surely someone must have had this problem too.

Nope, are you on a custom ROM or kernel?

No, not even rooted. It seems to happen most frequently with third party apps.

Maybe it is a problem with the third party app? ...

I've noticed it especially with skpye, but it has happened with stock apps like chrome and gmail too.
EDIT: just had it happen with the Twitter app. It seems it goes to sleep earlier than it should when the unlocking problem happens.

I had the same issue. Let me guess...you have a folio case with the magnetic smart cover feature?
Sent from my LG-P999 using xda app-developers app
No problem here...
I also at times have problems with the unlock screen.
The lock screen at times is just in a frozen state.
To fix I press the power button to turn of the screen and hit it again to turn back on the screen.
The lock screen then functions as usual.
Note: This happens even when I have no apps open.
Well as it turns out, a lot of the folio cases with the sleep/wake function use magnets that are too powerful. When the case is folded all the way back, the magnet is activating the sleep function. I almost sent my tablet in for RMA but then I realized it was the case. If it happens again, just let the flap hang and you should be able to unlock your device hope I helped.

I do not have the smart case and I have a frozen lock screen issue.
LCD often has wake up lag.

I have a folio case. Never thought that could be the issue. I'll try letting it hang freely from now on. Could someone tell Google about this so they can release an update to fix it? (since people without the case are having the same issue)

what do you think? is the problem in hardware or in software?
if the problem in software, there are a lot of apps doing what you want (on off restart whatever) , and you can install one of them.

If the button itself is defective and you are not under warranty you may be able to find a replacement on ebay. I have seen various phones being parted out there and the button should come with a replacement rear cover. If it is the actual switch on the motherboard you have a different problem though. Have you removed the rear case to test that switch? It can be done with a torx t5 screwdriver, a couple of guitar picks and a half hour of patience.

it seems to me something went wrong with your rom.. try to reinstall it by N-cry toolkit.. and then install one of those apps which gives you no need to this button anymore. just like what I do.

this same thing happened to me a while back. and force rebooting fixed it right away. it was just a software derp, hasnt happened since.

Screen unresponsive

So a few times a day, my screen goes unresponsive. The only way to unfreeze it is to turn the screen off, back on, unlock phone, and it all works great after that. I can also pull the s pen out and it will work but fingers do not. Seems that it happens everytime I am bragging and showing off the phone. Really annoying. Any thoughts?
I have done a factory reset, cleared cache, disable pen recognition.

I'm not sure what else to try at this point. I have read things about screen protectors and SD cards not being compatible. May try to remove those today.
Sent from my SM-N900V using xda app-developers app
Removed SD card, screen protector and case... problem gone. Now to reintroduce and find the culprit.
I also removed my case. Everything looking good so put my case back on without screen protector for a few hours. Still no problems. Now I am backing up my SD card and reformatted it. Copying files (mainly pictures and music) back to SD card no. Still no problems yet. Looks like my screen protector was the problem. User Manual actually states to not use a screen protector...

Interesting. What brand and model of screen protector so we can avoid. Have been running naked and perfect but was planning to add a screen protector soon.

Was just about to hit the buy button on Verizon for these screen protectors and wireless charger back since they're 25% off with corp discount. And, I was thinking of all the screen protectors out on the market the Verizon one would be validated to work. Thanks man for saving my butt.
I have the ones from the Verizon store and do not share any of these issues. I run naked with just the protector. Had it on since release date.

Well problem is back but not as often. Trying to decide if it's the case or SD. Leaning towards the SD. May try to run without it tomorrow.

Have you tried going to settings control scroll to bottom
Tick box to increase touch sensitivity
Or could be caused by magnet on your case if present
I have the same problem. I'll touch an icon on my home screen and nothing happens. I touch the icon 3-4 more times and nothing happens. Then after the 5th or 6th try, it'll FINALLY work. All this happening in the matter of 4-5 seconds.
It's really annoying and considering this has a Snapdragon 800 with 3GB of RAM I'm really baffled.

The sensitivity did seem to help some, but still happening.
After a 2nd hard reset, everything is looking good so far. Not going to change any stock setting for a while and see how it goes. Installed my usual apps only and synced Google account. So far no problems. Will wait and customize setting after I see if I have any problems.

[Q] What happened to my power button?

I was using my phone like any other day, and then I locked my phone and later on went to wake the screen and it wouldn't wake up. I did a "battery pull" (power+volume down) and it rebooted fine. When it came back on, I tried to press the button to lock the screen but to no avail. I went on and got smart screen on and it works okay but I'd like to know if any of you know what's wrong with it. It feels fine, clicks like normal. I haven't dropped it recently or anything. But sometimes, when I barely touch the power button, the power menu opens. I don't really understand that but if any of you have any help for me, that would be greatly appreciated. Thanks.

Just suddenly began working the next day. I don't exactly know why... Maybe an app or something had it confused. I really don't know.
