I got a problem with my Samsung Galaxy S2 I9100.
I have it for round about 8 monthts now and experimented with some custom roms. I installed cynogenmod 9, 10, 10.1 tested Syah Kernel and installed AOKP in DualBoot and so on.
Everything was fine until I installed CM10.1 as single boot.
There my phone started to turn off randomly and I thought that it would be a software mistake and reinstalled the Samsung stock rom. But the problem is still existing.
I dont use a firewall or antivirus program and did not checked up anything.
Can you help me with this issue or tell me how I should start detecting or solving the problem?
Thanks for your help!
I installed awg Antivirus and scanned my phone. Beside SWFPlayer there was no app which is "dangerous". And my "marked" settings were "Enable Debugging", "Allow Third Party Apps".
I now updated my phone via Kies to Android 4.1.2 but the problem still exists.
I think I got the problem. I already wrote it in my last comment. The batterie infalted and I think that's the problem. I ordered a new batterie and hope that's it. If not I don't know what it might be...
