I have a galaxy S3 that won't power up. The last time it worked, the battery was about 10%, I sent off a text then I plugged the phone into my car charger. After being plugged in for about thirty seconds it shut off,stopped charging, screen went black and got warm. I still can't get it to start up and when I try to charge it while it's off it shows no sign of charging such as the red or blue light or the battery Icon. I have bought a new phone but i would if I could start this phone just long enough to transfer some stuff. Any help would be greatly appreciated.
