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 ?
