Please tell us some basic information before asking for help:
Model Name: ROG II
Firmware Version: .65
Rooted or not: not
Phone randomly restarted (well not basically) it keep on looping on the logo and it's 4th time happening to me now.
Last time the loading bar kept hanging so whenever I touch the screen it just starts sliding.
This time I start tapping the screen continuously from the moment it got on the boot up screen.
Then instead of giving "can't load android system" warning, it booted into the safe mode and like always switches back light theme and changes wallpaper back to the classic theme wallpaper.
So basically it's not the hardware it's the OS problem.
Mods please look into it.
