[AC Question]

hey guys, MY s3 has just started to play up tonight. Every time I unlock my phone it freezes for a few seconds, then reboots itself. How can I stop this from happening?

Welcome to Android Central! A few things to try:

1. Wipe the cache partition: http://forums.androidcentral.com/sam...2-s3-tab2.html
2. If that doesn't help, then unmount the SD card (in Settings>Storage) and remove it. A corrupt SD card can cause various issues.
3. If that doesn't help, then try booting into Safe Mode, which temporarily disables all 3rd party apps. How to boot the Galaxy S3 into Safe mode? | Support | SAMSUNG Levant. If the problem disappears in Safe Mode, then something you installed is causing the problem. You may have to uninstall apps one by one until the problem disappears. If the problem persists in Safe Mode, then it's more likely to be a hardware or firmware problem.
