On Saturday, my phone just started resetting at random for some or other reason. Sometimes while using it, at other times I find it like that in my pocket.
I did read on the net for solutions, but nothing really fits so far.
Nothing was changed recently, no drops etc.
Since the problem started, I tried the following:
Firmware upgrade to 4.3 (was running 4.2?I think? seamlessly)
Changed battery around
Removed SD Card
Re-inserted SIM 'correctly'.
It does it on battery and cable power.
Failed power button seems likely, but wouldn't the power button screen come on? I tried on my friend's phone by holding it in, and although it resets, it first shows the options.
Will 'n factory reset help? Even after a firmware upgrade?
