Samsung: Remove the battery and wait for 10 seconds, replace the battery and press the power button. Your Samsung handset should then restart as normal.
OPPO: Use the built-in backup tool. Go to [Settings] > [Additional Settings] > [Back-up and reset], or click [Tools] > [Backup and Restore]. All your personal data, system data and applications will be backed up to phone storage.
Test your device after it restarts to see if the problem still exists.
