Hi,
Since a few weeks, I've been facing a very annoying problem. I have a samsung Galaxy S3 mini with cyanogen mod 11.0.
When I lock my phone, the screens lights off (as it is supposed to). But about every 30 seconds, it lights on, displaying the lock screen. Then it lights off, and starts the process again. Finally, my battery is being drained. It takes 4 hours to use 50% of my battery.
So I installed Wake lock detector to find the problem, but I cannot find anything relevant, so I cannot really debug by myself.
Could you give me a hand and tell me what I have to look for ?
Thanks.
UP. This issue is really annoying.
Am I in the right section at least ?
Ok, actually the bug is occuring only when the phone is not on AC.
When plugged, it behaves normally. So I wonder, is there a way to make the phone believe that it is on AC ?

So i've had this problem with my i9300T SIII for a while now what happens is ill get to about 1 or 2% battery basically right when the phone is about to die. The screen will flicker not on/off but the level of brightness in horizontal lines, and either eventually lock up or turn off. If i even attempt to reboot the phone after this has occurred 90% of the time i end up with a boot loop.
I would then have to hold the power button until the phone turns off but even after i charge it after this point a lot of the time it seems this has corrupted part of the memory on my phone where the only way i can successfully boot again is by factory resetting. This has started to become quite frustrating :\ i am now having to force myself to charge my phone before trying to turn it on again lol
So my main question is would this be hardware related? I am running Cyanogenmod 10.1 Nightlies.
If this is hardware related would i be able to send it into Samsung and get it fixed?
If its not hardware then what can i do about this?
The first time I've allowed my battery to get very low since installing CM7 on my HTC Merge and I'm now having all sorts of problems.
Firstly my screen won't light up. It's just completely black. The phone is on and the 4 buttons at the bottom light up but that's all. The phone is still responding to my touch as I can load apps and hear noises if I happen to touch the correct parts of the screen. It's almost as if the brightness has been turned way down, but I'm unable to see the controls to try turning it up again. I have tried booting to recovery mode but that doesn't display either.
Secondly the battery won't charge. Since the battery is drained I can only get the phone on when it is plugged in, but the orange "charging" led at the top of the phone never lights up. It just casually flashes like it ordinarily would have done when it was running from the battery. I have two batteries and they're both doing this.
I can't be 100% sure that these problems are due to the installation of CM7 but I've never experienced it before so i'm guessing they're connected.
Does anybody have any suggestions on how I can get my phone working again.
It's also worth mentioning that it is also no longer recognised by my computer
Sounds like a hardware fault, if you have the same issues in recovery as you do in your os then its very unlikely its ROM/software related
I don't your device nor have I taken it apart so its only guesses I could give you on which component needs to be replaced, LCD or flex cable are best guesses

Want to update on this as I've just had another look at it after a while.
With the battery having completely drained, I connected the phone to charge via my PC and the orange charge light lit up and the phone went into recovery mode without any assistance from me. After about 2 seconds the screen went off again.
When the battery has charged sufficiently, I am once again able to turn the phone on and it boots up... but the screen remains blank.
If I discharge the battery and then plug it into my PC, I am able to repeat the appearance of the recovery screen, but it always vanishes before I am able to do anything.
The screen must be surely be functional or how would I get those 2 seconds of display ?
Does anybody have any ideas of what I can do to get the phone working again?
I acquired a new battery and after fitting it the phone immediately worked again. The battery was completely without charge but the phone charged it up without any problems. However, as soon as the power ran low the same thing happened; the screen has stopped working and the battery doesn't seem to charge anymore.
Hello incredibly helpful internet people! NEW ROM NEW PROBLEMS!
So I love my experia z, but it has a problem. When it has become fully charged 87% charged, it wakes from sleep, turns on the screen. The screen then dims and goes black like it's going back to sleep only to instantly wake up again. This even happens if I press the power button to lock it. The processor seems to run hot during this time for hours at night while my phone is charging which can't be good, and I can't charge to 100%. In other news my phone turns on by itself when you turn it off. So my guess is that I have a buggered USB connection somewhere?
Any ideas what this could be? I had this on a SlimKat, and now on scrubber port.
Thanks!
Hello.
Try to change usb cable/ charger.
Are you even using stock one?
But before that I would recommend to check on your software, maybe some of the programs causing wake locks.
You can search for "wake locks", maybe you will something useful.
Hi all,
I have recently noticed when charging my phone during the night that it seemingly randomly turns on the screen, goes bright and then shows the boot logo. After a few seconds it then shows the lock screen where I can enter my pin. It doesn't seem to actually reboot.
Does anyone have an idea about what is going on? Is it faulty, do I have a virus or something else maybe?
Thanks
Hi.
I have exactly the same issue.
Today I woke up and at the same time my phone was "rebooting" and ended up in lock screen, keyboard was showing.
And the phone had been on wall charger all the night.
It is really weird and I think it started to happen after the latest updates.
1- don't leave anything charging over night. The phone will get little charges to the battery to confirm it's 100%, thus reducing battery life. You may Google it.
2- have you updated without factory reset? If so, backup with native app and do it. Most problems disappear.
This problem started happening two weeks ago and it's quite annoying. Running Android 5.11 Archidroid with the latest Archikernel version on my phone.
The problem is that my Galaxy S3 seems to freeze when the screen turns off. If the screen is turned off for maybe half an hour or more, pressing the power button will not wake the device. In an attempt to figure out if it's a broken power button, I set the home and volume buttons in the settings menu as keys that will turn on the screen, but that doesn't work either. The only way to fix the issue is to hold the power button to restart the device and doing that every couple of hours gets really annoying. Trying to turn on the screen literally does nothing, as if the phone is turned off.
When the phone is not charging, the interval between the freezes seems to be much longer. The phone will work perfectly for a couple of hours without the above mentioned problem but when on a charger it quickly screws up.
Now, I don't believe my device turns off during this "process". I've turned on the LED for charging and whenever I'd get the screen freezing problem I'd unplug the charger and the LED wouldn't go away, it'd still light up as if the phone is connected to the charger, which it isn't.
Anyone have any idea on what the problem is? I've never experienced this before and it started happening all of a sudden.
How low is the kernel clockspeed running in sleep mode?. Should be at 200mhz at the very minimum!.
Beamed in by telepathy.
If this does not happen on a stock ROM, it would be a problem with the ROM and the phone.
