I was watching youtube on my samsung galaxy stellar and it turned off which is normal because it does that a lot. But in this case it wont even reboot. I tried turning it back on and all it will do is light up for a second and turn back off. If i plug it into the charger, it will do that over and over again nonstop. Keep in mid i had 100% charge when this happened so my phone is not dead...any pointers?
