When I turn on my phone, this message pops up. Then, a few seconds after it pops up, the phone restarts. I can't even get into my settings without the message popping up and my phone turning off and on again. This started last night, and I tried again right when I woke up and the problem is still there. I don't want to do a factory reset because I have so many pictures, apps, and contacts that I would hate to lose. BTW I have a Galaxy Ring

I've went into recovery mode and cleared cache multiple times and rebooted. It still keeps displaying this message. pleaseeeeeeeee help!!

Welcome to Android Central! Try booting into Safe Mode, which will disable all 3rd party apps. If the problem goes away, then something you installed is causing problems--you'll have to uninstall apps one by one until the problem goes away. If the problem persists in Safe Mode, there may be a hardware issue, in which case you may have to contact Samsung or a repair shop. Here's how to get Safe Mode on a Galaxy S3--the steps should be the same for your phone: Restart the Device in Safe Mode - Samsung Galaxy S® III

You could also try unmounting your SD card (in Settings>Storage) and removing it, then rebooting. A corrupt SD card can cause various problems.
