[Q] Screen Suddenly Turn on (GNEX)

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

[Q] Galaxy s2 hercules wont boot after 3/24/13 nightly installed

Hello all,
I installed the newest Cyanogenmod 10.1 nightly (3/24/13) and the phone worked just fine for a few hrs. But when I selected Google Play the phone turned off and got stuck in a boot loop. I tried rebooting in download mode by connecting to my PC while holding volume up+down but it doesn't wotk. I tried rebooting into recovery but still no luck. No matter what I do it just boots to the Samsung logo then just vibrates in 3 second intervals.
I'm ok with flashing my phone to stock and rooting again. But it wont do anything but vibrate every few seconds no matter what I try. I'm desperately trying to get it into download mode. Any suggestions will be greatly appreciated.
Did u try removing battery & then try to reboot?

Yes, I did.
Weirdest thing happened though. I got frustrated and left the phone vibrating on my desk. I came back 10 minutes later and it's back to normal!!
I have no idea what happened and I don't plan to try to figure it out. I'm happy it's back up and running.
Thanks for the reply though. Very much appreciated.
That is weird

[Q] tab sm T210r bricked?

I think I've bricked my T210R 7.0. I was trying to Oden back to stock using the Kies rom. all seemed to be going well till I attempted to reboot the tab got stuck on the samsung screen. managed to get it back to the download screen, but before I could attempt to run Oden again got called away. wen I got back the screen was dark and the tab would not respond at all. I have had it charging (with the 2amp charger) for 24 hours now hoping it was just a dead battery to no avail... anyone have any suggestions?
No suggestions this is depressing...

Update... plugged the tab into the charger and ignored it for a few days, was getting ready to call samsung, decided to try the phone one last time and as I pressed the power button the batt indicater lit up showing a full charge. Put the phone in download mode re flashed the stock rom, let it reboot only to watch it sit on the samsung screen, finally booted into recovery, cleared the cache, reset the phone, rebooted and tab started up perfectly.

No auto rotate

Not sure if it's a coincidence but I recently update to 4.4.3 and the auto rotate on the N7 2013 not working. Will only rotate when certain apps force it to. Anybody having that problem or solution

Yes. It kind of drives me nuts. The last rotation I used sticks after a few hours of leaving it in sleep mode. A reboot fixes it for me.
Crap reboot not working for me. I'm using an app that sits in the notification bar that will force the rotate in the meantime

Me too not working
Have you tried flashing a custom rom? Auto rotate works fine on my N7 running Pac-man 4.4.3 (6/9 nightly).

That happens to me as well. I'm using an apo to force rotation whenever I want to rotate it, otherwise a reboot usually fixes it, until it goes back to sleep.
Better of with an app.

Don't know if it's a cure, but this happened to me when I upgraded the rom (4.3 variety). Thought the gyro sensor was gone 'cause I then flashed 2 different custom roms and it didn't budge. So I took it apart, and finding nothing noticeable, I disconnected the battery for a few seconds, reconnected it, reseated all the cables and closed it. Then it worked again.
This thing is fickle!!!
Same issue here, reboot fixes for a while. Not real comfortable with taking it apart...
