Recently my Samsung Galaxy S2 has been doing this very strange thing, it just switches off on its own. However the screen flickers like two or three times really quickly before it switches off.
It all started when i went on holiday and the signal was poor up in the mountain (not sure if this helps but i'm gonna type it anyway). so since then I've had it on flight mode accessing WiFi only and making use of Bluetooth, yet it still randomly does it. are there any logs I can check to maybe see what the problem is!?
