My camera keeps saying warning failed and exits out the app. I've tried restarting phone, reseting the app settings and shutting phone off and turning back on. Anyone have this issue?
try it in safe mode and see if it's giving you the same warning. if not, then one of your 3rd party apps is causing the failed warning.
submit an error report via samsung members app if it continues to fail (members app > + button > error report)
