I've ran into a very odd problem recently: I can't turn off the screen while I'm in the lockscreen - it keeps flashing on and off constantly every 2 seconds.
I have to unlock first, and than the screen shuts down absolutely fine (using the power button / inactivity timeout).
This also happens when receiving an unanswered call - the lockscreen keeps blinking on and off until I unlock it.
I've tried re-flashing the ROM (and checking out other roms), and another kernel - no help, it still happens.
I've tried checking it out in safe mode - happens as well.
Happens when the phone is plugged or unplugged to USB, the connector is working fine.
Happens on 4.1.2 & 4.2.1 with all lockscreen options (slide PIN password etc) - with every gadget / extra feature disabled.
I've tried disabling every app I can think off, switch to airplane mode (in case it comes from some signal / wifi), and checking with airpush detector & AVG.
This is driving me crazy, is there a way to debug this and find out what keeps waking up the phone into this freaking loop?
Update: I've found a partial solution - using an alternative lockscreen (tested with go locker) seems to solve this problem.
this means something is wrong with the vanilla lockscreen apk / some setting.
does somebody have the 4.1.2 lockscren apk available?

I probably know this may be a hardware issue, but wondering if anyone has found a remedy--did a search and cannot seem to find if anyone is experiencing the same problem(s).
Bought used SGS2 that had Cognition 1.6 on it, Flashed Checkrom HD, Flashed back to stock JI3 w/ new bootloader and left un-rooted.
-Screen turns on after screen timeout (15 seconds or 30 seconds)
-Changed to pin unlock--same thing--turns on and remains on
-Screen won't go black/back to screen timeout
-If i push the power button, screen turns off, then after about 20 seconds or so, screen turns back on and stays on
All reboots remain the same, pulled battery, remains the same--screen comes back on. Completely drains the battery
Any ideas? ????
I'm afraid i don't have a warranty and i've already tried contacting this pitiful seller...

Update: 12/1/11
- Replaced USB Flex cable purchased from ebay, but it was version 2.1 instead of 2.2 that i replaced
- Issues of screen randomly staying on is for the most part, gone, except i've woken up to the screen being on a couple times w/ a text message (and screen stayed on)
- Cannot connect to USB via download mode anymore
- Cannot connect to PC (states unrecognized)
- I get random "Back button" presses while using an App or the browser--sometimes multiple times where it goes back to the home screen
- Charging is slow and only reporting "Charging USB"
- Purchased another one from a different Ebay supplier--hopefully, it's version 2.2
*********
Update: 12/12/11
- Replaced with 2.2 revision flex cable from ebay seller yqmama
- Cleaned flex cable connections on main PCB with electronics cleaner
- Charging is now saying AC when plugged in
- Download mode and Recovery via USB work flawlessly
- No other problems seem to be apparent, except the back button went crazy once since replacement
- Seems that the phone is now ready for daily use
My guess would be a rogue app causing it. Have you checked what's waking the phone? Something like BetterBatteryStats should be able to help you pinpoint it, if that is indeed the cause.
If that's not it, at any point have you tried factory resetting the phone?
If you're using JuiceDefender, make very sure you disable the timeout function. It's known to turn on screen by itself.

I literally have no apps installed after i did a factory reset, and i formatted usb storage. I can try betterbatterystats, but i feel like i'm almost at a loss.
Update:
-Installed CM7 nightlies and random screen turning off and on went away, but new problem--capacitive buttons would not work
-Installed CheckRom 3.3.1 and all was going fine 11/15/11
-Installed apps (didn't use TiBackup) from market
-Installed theme from KitchenPro (ICS Domination)
-Added widgets from homescreen (added SamsungWeatherClock--i.e. accuweather)
-Went home, connected via Wifi
-Saw screen turn off and on several times
-Used Watchdog--came up with Event/O and Suspend as acting up
Are these what is causing my screen to wake and stay on sometimes??
updated 1st post w/ findings thus far after replacing USB Flex cable (charge port)
Have a very similar problem as you describe with a water damaged Galaxy S2. I replaced the USB flex cable and it solved the problem I was having with the phone refusing to stay off. However, the screen will not turn off, when I briefly press the power to turn the screen off, it goes off for a second and then it turns back on. I am going to be replacing the home button flex cable when the part arrives. When I open it up to do that, I will be cleaning more parts in hopes I can solve the screen-no-stay-off problem that I'm having.
****UPDATE.
Used a bit more contact cleaner on some of the areas I had overlooked, put it back together and the screen's behaving nicely.
[Q] Phone get stuck with screen locked. Rebooting starts an endless "startloop"
Hi, I have this Galaxy S3 i9300, with Wanam ROM and Boeffla-Kernel 2.12.
Sometimes, when I lock the screen, it just freezes in there. I'm unable to wake it up, and the LED keeps flashing the last notification.
Most of the time, I get notice of it when I receive a notification (it rings) and the phone cannot wake up. Calling and trying to trigger another notification does not wield any results.
The weird part is this: When I restart it, the OS starts as it should, but it "skips" the lockscreen (when I restart my phone, first thing I'm presented is the pattern lockscreen, all Android default), and it goes directly to the home screen. The touch screen is unresponsive (but it does vibrate when I press any of the two bottom buttons), but phone is still alive (few animations plays smoothly).
Then it restarts. The startup LED (fading blue to bright blue) doesn't turn off (normally it would turn off even before the lockscreen is presented).
Disabling the lockscreen wouldn't solve the problem, nor does starting on "safe mode". Same issue.
Booting into CWM and wiping data/cache folders solves it, but resets my phone. Restoring a backup (data folder only) also works.
Funny fact is that even with a fresh backup (which works), it might just hang up like before (although I didn't modify/install anything).
Logging files should give me some info, but I don't know how to retrieve them, let alone on this condition.
The only step I did so far to try to solve it was to disable a notification program (Logical, it seems to hang up when I receive a notification, and as a wipe to the data folder solves it, I presume it's an rogue app. But never, ever I had a problem with this app, but who knows if on an update, it's crashing my phone)
Does anyone have any information regarding to this? I've never seen something like that.
How do I recover my logfiles during an emergency?

Had another lock-up. No notifications received and the notification app was disabled. How do I get the log file?

Hi All
I am running CyanogenMod version - 12.1-20160529-NIGHTLY-klimwifi
Kernel version 3.4.105g766de8b
I have as you can tell by my heading an issue, my tablet after using the plex app decided to power off and would not restart until I tried turning it on in recovery mode. When it did turn on the lock screen did not display the usual text (swipe to unlock) and the notification drawer would not display or pull down.
I tried cycling it on and off a few times and alternating between turning it on in recovery or download mode but no response, eventually allowed me to access the notification drawer and by creating a new profile I could access everything again. I deleted this profile just to make sure and tried it again and discovered the if I hit the volume buttons a few times everything works fine the tablet though has become slower in its response.
Has anyone else come across this issue.
I have been running my Tablet Z (pollux_windy) on the latest Oreo release (15.1) . Have installed a few nightly updates - but the problem below keeps occurring.
It generally runs really well - but I have discovered something that seems to be causing issues for me and wondered if anyone else has the same issue.
I like to use the full real estate of the screen, so found the Settings/Display/Expanded desktop setting that lets you hide the top status bar and the lower navigation keys go into autohide mode (you swipe up from the bottom of the screen to see them).
First time I enabled them all seemed great - Then I left the tab and the screen timed out.
I tried to wake it up (using the power button or double tap on the screen) - Nothing.
Tried this quite a few times over a few minutes.
Did a Hard power off.
Restarted eventually. Seemed ok until the screen blanked out - then the same as above.
I did eventually get the screen to wake back up without a reboot by trying the double tap and quick press of the power key. But it took quite a few attempts.
Finally I turned the full screen mode off (ie brings back the status bar and nav controls) and everything was back to normal behaviour - ie always wakes back up when required.
I have tried changing the expanded desktop mode several times and it always locks things up after the screen times out so have now given up on it.
Anyone else finding that setting this mode causes lockups?

Hello!
Please write your problem to an official bugreport https://wiki.lineageos.org/bugreport-howto.html to let the LOS developers team about the encountered issue.
Thanks. Signed up to add the fault and found someone witha different device reporting the same bug around a week ago.
Added my confirmation of the problem with different hardware.
Fingers crossed someone may have a look at it when time allows.
