Problem unlocking N7? - Nexus 7 Q&A, Help & Troubleshooting

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?

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)

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.

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

Lockscreen freezes after sleep

Hello!
Just got my Nexus 4 and I am loving it. But my Lockscreen sometimes freezes when I hit the power on button, or it is at least unresponsive. I have to turn off the screen and turn it on again to unlock. This happens everytime the phone has been locked for a while.
Any fix for this issue or should I get my phone replaced? Seems software related

I have the same issue and wants to know the reason.
I have the same problem, and I think i have found a way to replicate the issue.
1. Turn off the screen.
2. Wait around 5 seconds.
3. Put three fingers on the screen at the same time.
4. And immediately without moving the fingers turn on the screen.
At this time the touchscreen doesn't respond or it has some kind of lag and you have to reunlock the screen to make it work again.
Can anyone test this?
Sorry for my english.

Ive been having this issue for a while, even through the most recent update. I tried the three finger thing, and it doesnt freeze it. Anyone find any fixes yet? Maybe it's an app?
Happens to me too, I thought I was the only one.

I can reproduce using this method. It's very annoying when it happens in the wild though, I was unable to unlock at all the other day, had to power off and on the device. Also wasn't able to answer a call !!!

i have the same issue too. I thought my unit was defective.
So is this a software or hardware issue?
Hi,
I seem to have the same issue. It renders my phone useless. While trying to figure out what exactly is affecting it. I found if i enable under developer option >> input >> show touches the next time this issue happens i can see that the phone screen is constantly being touched (w/o having any finger on screen).
I am also awaiting any solution for this issue.
Let's just hope that this can be corrected with software.

[Q] Stuck after phone call

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

[Q] Screen "presses on its own"

My friend got a nexus with 4.3 on it that lives on it's own. It seems to make "touches" in different places from time to time. Anyone has any ideas on how to fix it?
Best regards,
><///*>
In most cases it is caused by the moisture of the hand.
At least when my phone or tab does this, I lock the screen and wipe both the screen and my hand with a cloth and it solves the problem.
Well, this is happening without even touching it so I'll guess it's not about any moisture? Or do u think there is some moisture sticking to the screen and therefore the screen thinks it's a finger that's pressing the area?

i currently have this issue. it's not really a fix, but what i do is just lock it, then unlock it, and it's fixed.
Well, that isn't a great solution if the "problem" shows itself and you fix it after it happens
And about the moisture, that's apparently not the problem in this case regarding to my friend.

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.

Still happening with SD removed, screen protector off and case off. But way less often. Uhhhhh. Just when I thought I had it figured out.

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.

Three hard resets later, problem is miraculously fixed. Only problem is I no longer have the Samsung App store and Samsung says they can't fix that.
