Galaxy S2 crashes on battery mode
I have a weird problem. My galaxy S2 is getting crashed when I use some apps like,
sync up with GMail, play TempleRun game etc., suddenly screen goes blank, and nothing happens. And when I restart, it crashes again during booting.
But surprisingly this crashing is not happening when I do the same while connected to external power, i.e., when it is charging.
I thought it might be with ROM, so i've flashed different ROMs like, RootBox, CyanogenMod etc., but still it is getting crashed.
Even I changed Kernels also, Dorimanx, Siyah and even base kernel which comes with Cyanogenmod too.
So any body could help me out ?
I tried to get the log, but don't know how to check/get the log where I could see the crash file/app.
