[Q] Screen Suddenly Turn on (GNEX) - Samsung Galaxy Nexus

Hello,
I have an issue with my Galaxy Nexus, After i upgraded to 4.0.4 it happens that when in standby mode, the screen turn on for 3 seconds and then turn off by itself many times.
The phone is rooted, and not few applications on it, same when i had 4.0.2
Does anyone know what is causing this?
Thank you,

Is it saying its charging when it does it?

Nope it doesn't say charging.

Hmm. Wondered if it was the charging port problem... I had it n done some Googling to find its quite common, fixed it myself. I'd check what's causing wake locks.... alternatively a factory reset should help..

Had this issue on my xoom and nexus. Uninstalled a few apps I had on both to try and narrow it down and haven't had the issue sense. My rouge app was a tablet wallpaper app.

Some apps use the FULL_WAKELOCK to do certain tasks, and that turns the screen on. Check some apps that might do that, the permission for that is "Prevent device from sleeping"

Thanks guys

TouchScreen stops working occasionally

Hello,
On about 3 or 4 occasions I've gone to unlock my phone with my face and its failed so I've gone to pattern unlock as fail safe only to notice that the screen is unresponsive. No matter what I try it just doesn't respond. A reboot fixes this.
Has anyone else noticed this? Its not like the other touchscreen issues where it seems multi touch related, it does nothing.
Once time I managed to unlock it with my face realising the issue and I found the touchscreen still didn't work even when unlocked.

yes.. happened to me couple of times, but after i upgraded tp 4.0.2 from official google's image there are no problems..
it happened to me after i speak on my phone for a long time anf switch off the screen and switch it back up again.
but no problem now
Glad to hear its not just me then. It does seem a software bug.

It did it again today. At least I know its not Beautiful Widgets as I uninstalled that thinking it was that.

Anyone uses JuiceDefender ?
Cheers~
I have had same issue, I'm on 4.0.3 aosp. I have noticed, if I leave phone for a little while without use, touch screen does come back, most of the time
Running juice defender as well, might try removing and see

I removed Juice Defender but I still had the issue. It just did it again while charging. Are you all using face unlock?
Sent from my Galaxy Nexus using Tapatalk
No. Never used face unlock. Do use light flow, others?

No , I`m not using face unlock. Instead , I do have installed Light Flow !
Cheers~
Unfortunately I don't have light flow installed.

Glad it isn't only me then!
I posted in another thread suspecting it was Juice Defender but after uninstalling it i got the error one more time. I still haven't done a factory reset to check if it's still there, though.
How do you guys reboot when the screen becomes unresponsive? Do you just hold the power button in until it turns off/reboots? It seems like it's worked for me but only maybe 3/5 times.
I just pull the battery out.

I can confirm this problem.
I'm on 4.0.2 stock Google build, no juicedefender.
Only happens on lock pattern.

If you set face unlock, you can unlock and find it still doesn't respond.

I'm running stock 4.0.2 and I have this problem a fair bit. I use a numeric password unlock, and whenever it freezes I just wait a few minutes and the screen becomes responsive again. Very annoying though. I hope this issue is resolved soon.
I've not had any issues for a while. The odd random reboot but no screen freezes anymore.

occurred on 4.0.4
occurred on GSM version running 4.0.4. received an call and could not attend, I don't use any lock pattern. last thing I did before this occurred was to install call filter, not sure if that caused the issue.
I had this problem on my vzw nexus. It just started happening more and more to the point that I had to hard reset to get it to work. The problem never went away so I got it replaced. Then had the replacement replaced due to unrelated screen color issues.

No deep sleep no wake lock either solved

My phone doesn't deep sleep but I don't have any wake locks. I'm on aokp m3. It'll deep sleep for usually the first half hour of the night but then sits at my min all night and until I restart it. It never deep sleeps more than 2 hours even if its on multiple days

No, it's killing your phone!
Have you checked which app is draining your battery?
Have you tried other ROM's?
Factory reset?
Wiped Cache?
I've wiped cache. Done several resets while flashing rom updates. None of my apps are really using battery. I honestly can't find a single app keeping my phone going I'm almost ready to start blaming widget locker. Tonight ill try disabling it.
Sent from my Galaxy Nexus using XDA App
I would format, and reflash, remove any gaps you might not be using, and not install a single app except for a cpu monitoring app to check on the deep sleep.
Let it sit like that overnight, and in the am check your results. If you see a difference and are getting deep sleep, then its obviously a rogue app thats keeping it awake. After that start adding one app at a time, until you find the "bad app"
I know it takes time and is boring, but thats the beauty of Android and open source...
What kernel are you using?
I'm using Franco's kernel #16.1 right now. My phone has been like this basically since day one but its bothering me lately.
Sent from my Galaxy Nexus using XDA App
Really can't find out what's doing this. I'm not getting any deep sleep now. I've gotten rid of any app I can think of. Can anyone think of any "bad apps" off the top of their head?

Try downloading watchdog and setting it to aggressive. That might help you find something

I'm actually getting an audio out_1 wake lock but idk. I'll try that
Facebook keeps alerting me... Odd

Lol it was lookout... Uninstallrd it and its deep sleeping just fine.

Screen automatically turns on!!

Hi!..I have an issue with the screen. Sometimes when I keep my phone aside my phone screen suddenly lightens up shows the pattern unlock page and automatically turns off. This happens 4-5 times in succession. First I thought its because of the antivirus app so I uninstalled it but still the problem persists. Does anyone know why this is happening? Any suggestion will be helpful.

I think we'll probably need a lot more information than that...
It could be anything. When I have mine plugged into my computer and the screensaver kicks on or when the laptop falls asleep, it does the same thing to mine because the USB power is cycling but it could be anything. Are you rooted? What ROM? What kernel? What is the battery state? Go into settings > apps and see what's running, start testing those out.
If your rooted, the problem with the screen waking is possibly superSU granting an app root access. Its usually a toast pop up saying that an interactive shell has been granted. At least it has been for me in the past. You can turn the notification off in the superSU settings.

my gf's HD2 used to do the same thing after she dropped it on its bottom right corner.
Sent from my Galaxy Nexus using xda app-developers app
My Nexus does that from time to time. Running AOKP JB preview builds. Latest franco kernel. Screen just turns on. No popups, no notification, just shows the lock screen until it times out again. Doesn't do it enough to worry me but it is a little odd.
No I have not rooted my nexus, using ICS 4.0.4. My phone is yakjuxw so haven't got the JB update yet..I have general apps like Facebook, whatsapp, power toggle,etc to name few.

Next time it does it see if your phone says charging even though not plugged in. Could be a bad charge port on your phone.
Had the same thing. The culprit turned out to be folder sync.

blackout. screen wont turn back on

Anyone have the problem where if you turn your screen off sometimes it wont turn back on but its still on. like when im listening to music the screen will turn off and wont turn back on but the music is still palying, still got buzzes from notifications. have to pop the battery out
That's usually referred to as a Sleep of Death, or SOD, around the forums. If you look around, you'll find a lot of posts about them.
Anyone else with info on this when I search I get nothing but bull**** threads about different Roms. I'm running stock gnexus

Are you on android 4.2.1 still? If so, try turning auto brightness off. I'd your have developer settings enabled then you can turn off animator duration.
Not on 4.2.1? Then I have no idea...
Verizon Galaxy Nexus haven't gotten 4.2 .1 yet I thought. So I'm still on 4.1 .1

Screen turns itself back on

Hey guys. I'm new to the Galaxy Nexus forum and I need help. My phone has been turning its screen back on after I lock it. Most people say its a hardware issue but I just got this phone and its brand new. Is it a software issue?
Sent from my Galaxy Nexus using xda app-developers app
You bet it can. Try factory resetting your phone. I do assume you're still running stock everything.
If you are and that fails, a hardware issue could be due to a sticky or faulty power button.
I'm running stock 4.2.2 and there's barely anything on it right now. I'm the second owner of this phone but the original owner never used it so I don't know what else is wrong with it.

usually caused by an application (generally by a live wallpaper). boot into safe mode and see if it persists.
