Galaxy S3

[AC Question]

My Galaxy S3 was working just fine, when out of the blue it shuts down and will not restart. Any suggestions prior to taking it in?

Welcome to Android Central! Try one of the following:

1. Try a different battery, since your battery might have failed.
2. If you have an external SD card inserted, remove it and try rebooting. A corrupt card can cause various problem.
3. Try booting into Recovery and then wipe the cache partition. http://forums.androidcentral.com/sa...ing-into-recovery-mode-galaxy-s2-s3-tab2.html
