So today, my phone suddenly started turning off and on again until it decided it wont even turn on. I've tried taking the battery out to see if that will restart it, and it turns the phone on until Galaxy S3 logo pops up then nothing happens. I also think the lock button maybe broken or something I'm not sure. I don't have enough money to buy a new phone so i would like to have some help from what seems like a bunch of good people like you. Thanks in advance.
