[Resolved] Troubleshoot Unfortunately Gallery Has Stopped on S7

Reasons: Why Does Gallery App Get Stopped?

To be relieved, this problem is nothing to do with your operating system nor would it break down your device. The reasons why the Gallery app crashes can be concluded for 2 reasons:

1. Please check out whether photos are being synced automatically but the process goes wrong. If you're using "Google Photos", launch it and stop syncing. If you've set up auto-backup with Samsung Cloud, you might as well switch it off temporarily.

2. Another potential culprit is cached data created via the Gallery app. When cached data got corrupted, it will result in malfunction. I'm going to show you how to clear cache in Method 1.

Notes: Try These Before Going Any Further
