so i in fact have had this phone randomly restart on me. it happens probably once a month. today when i plugged the phone into my car to listen to music the music didnt come on so i usually hit the power button and it comes on immediately then. this time it didnt and i looked at the phone to see that the screen didnt come on at all. i tried holding the power button down to boot up the phone and that didnt work either so i had to remove the battery and put it back in for it to finally boot up. phones is working fine now but what the hell man??
