[Q] Galaxy s3 won't turn on
I was charging my phone on my computer and I was using an app until suddenly my phone just shut off. I tried to turn it back on but it would only vibrate and stay on the black screen. I tried the battery out for like 5 minutes and put it back in. I put it back in my computer and then it vibrated a few times. It turned on for a good three minutes and then it shut off again. I remembered usually when I charge my phone it would vibrate until I hold the power button and the Samsung symbol would pop up, but now it keeps vibrating and it won't turn on even if I hold the power button. It would only work for a good two minutes if I take out the battery, put it back in my phone, and charge it in my computer. Help?
