Hello all I have a galaxy s4 and an annoying problem is it will appear to have shut down as when I hit the power button to look at it the screen won't light up but if I have received a message recently the little message indicator light will still light up and so a moment later my phone will just reboot I've looked at the battery its not deformed or bulging I've wiped the cache partition and removed any apps I've installed well before the problem started I'd like to not have to restore it to factory conditions is there something I haven't thought of
