Why does my S3 keep turning off all the sudden?

A

Android Question

Guest
I have a Galaxy S3 and it has been working really slowly for a couple months and the Battery was dying pretty quickly. So then I did a manufacture reset and after that it got even worse. Now my phone will just turn off all the sudden (sometimes the screen will grizzle before), sometimes it turns back on after and all the battery will be gone (it'll be at like 1-10%), sometimes it just stays turned off. Also sometimes it will hang itself up and I have to take the battery out to start it back up. Please someone help this phone isn't even 2 Years old. It's a no contract phone with 8Gb internal memory.6
