Lockscreen freezes after sleep - Nexus 4 Q&A, Help & Troubleshooting

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.

calibrate screen sensitivity?

Hello everyone,
Curious if anyone is having the same issue as me? I have tried multiple roms, stock, with and without kernels.
I am having some touch issues. Either I have to press harder then normal at times or multiple times for my press to register. Its getting quite annoying. Not sure if this is a defect or if i can modify something within the system files to make the screen more sensitive or if there is even a way to re-calibrate my sensors/screen?
Thank you in advance,
DFL
Did you figure out what was wrong? ... It just started to do the same with me... Even to right this was a pain in the a$$...

Well, I've rebooted in recovery mode, wiped the cache and it's back to normal now... I know it's just a temp solution, but you might wanna give it a try

hmmm... wiping cache fixed? i bet systemcleanup active would help then. I will take your advice and try out that app systemcleanup on my tab. I use on my phone Nexus S just didnt think the N7 would need it due to its specs.
Thanks mate, ill give it a go.

Has anyone decided if this is a hardware or software problem? I've started having the same issue. Turning off the screen sometimes fixes it for me but not always. A reboot always fixes it.
Like just now... I was playing Zenonia 2 and in the middle of a battle I suddenly couldn't get the touchscreen to respond. I hit power to lock the device and immediately tried to turn it back on with power again... but I couldn't even get the unlock screen to work. I set it down for about 30 seconds and when I tried again it was fine. I pulled the game back to the top and it worked fine.
When this happens the "soft" buttons (back, home, etc) always seem to work just fine, so I'm inclined to say it's really a software problem.
Running stock + root.
My thought is that it has to be a hardware issue, or if everyone with the issues is rooted than it could be from the root. My device has fantastic response however I am not rooted.

I would think hardware as well, but the home and back buttons always work and they use the same touch surface...
I got the same thing here and rebooting appears to fix it. Sometimes it is so bad that I cannot move icons from one screen to another.
Did you guys try flashing stock 4.1.1 using fastboot or the toolkit? If that does fix it then its probably hardware problem.

I had the same problem ! solved by turning off the screen and turn on it
I have the same issue and mine isn't rooted yet so I don't think it is an issue with that. A wipe of the device doesn't help but a reboot usually does. This is my second N7 as the first was a warranty replacement for the headphone jack issue. The first never had the issue so I think it is an issue that should be addressed. I am outside my 14 days so I might have to go through Asus now.

For what it is worth, I just called Google and they are going to send me a new one. The lady that assisted me stated that she has had a few complaints with this issue and that they just replace it. N7 #3 should be on the way in a couple days. For some reason she said that the device wasn't set up properly in my profile so it will add a couple days to the process because of the long weekend.
Not a big deal. I have lived with it for a while now. At least they appear to be taking care of it and I wasn't transferred to Asus. At least yet.

Touchscreen Unresponsive Sometimes

Hi, wondering if others had similar problems or fixes.
After a while of use, the touchscreen becomes unprecise and quite unresponsive. For example, it becomes difficult to input strokes or use the keyboard. This problem disappears when I immediately sleep and reawake the device.
Any ideas?
Thanks!!!

I have the issue sometimes too. Nothing to write home about. I just turn off the screen and turn it right back on and it seems to work. For the money and performance this thing is my new love. I haven't turned on my laptop in 3 days.

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.

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

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)

From what I've seen, others with similar problems have returned their Nexus 7 to the store they got it from and exchanged it for a working N7. I would recommend you do the same. If you got yours from the Play store, start an RMA. If you got it from a B&M store, exchange it.
Since you've only had your N7 a week, you shouldn't have any problems exchanging it.

It seems like it's an issue with the touchscreen itself. I have no idea how to verify or solve this issue, though. That's why I would personally exchange the N7 as defective. I would think that since your problem is clearly demonstrable, it would be easy to exchange or RMA.
But there may be a solution around that someone else has heard of. If anyone with greater knowledge of touchscreen issues wants to weigh in on this, please do.

I just started seeing this issue. At first it was only happening within apps. I thought it was issue with maybe stretching the app to a larger screen. But I started seeing it on the home screen.

There was a fix posted here somewhere for a package called surfaceflinger-fix.zip you flash in recovery. Made a huge difference on the touchscreen non responsive issue.

I have also experienced this. I I didn't try turning screen off then on but I rebooted then it was fine again.
I'm more inclined to think that this is a driver bug than a hardware fault

Anyone else sometimes experience touches not registering on the touchscreen?

Randomly it seems, when I tap on the touchscreen on my new N7 2013, nothing happens, and I have to repeat the process several times before my touches are registered.
Does anyone else have this problem?

See my thread titled " Another touch issue, with reproducible steps".
Go into developer options and enable "Show touches" and "Pointer location"
If you see your touches registering but the app isn't responding, it is probably a problem with the app. If you see random stuff on the screen, probably a problem with the digitizer or digitizer in combination with the driver/software in this release.
Ive experienced this a few times and it seems to be a software /hardware interface issue with particular custom rom builds ive installed. I know the touchscreen hardware itself was fine when I forced reboot into recovery and the touchscreen worked as normal in custom recovery.

I wouldn't. If you had a Verizon Galaxy Nexus when it came out, you'll remember that it had the same issue with certain points on the screen (lower right hand corner) when using multi-touch applications. The entire screen would either stop seeing input or start going erratic and creating faulty inputs that weren't happening. It isn't a hardware issue, proven by some users experiencing it and some not. The only time I've experienced it is in the Netflix application while trying to choose a show to watch. I re-boot the application and viola, no more issue. Some in this thread even are stating that they only see the problem sometimes after getting the 4.3 update.
In short, it's software and not hardware.
Same issue when not touching with both hands somehow (like if the tablet is flat on a table).

Haven't had a problem with mine. I just got it today, and it's worked like a charm. I bought mine from Gamestop if that helps any.
