Advanced troubleshooting

Remove cases & external batteries

If you’ve put a third-party case, external battery pack, or other accessory on your phone, try taking it off while you troubleshoot.

Make sure that external accessories don’t cover your phone’s sensors or touch its buttons.

Consider resetting your phone to factory settings
IMPORTANT: A factory data reset will remove all data from your phone. While any data stored in your Google Account will be restored, all apps and their associated data will be uninstalled. Before you perform a factory data reset, we recommend backing up your phone.

Tip: If an app that you downloaded caused the issue and you reinstall that app, the problem could come back.
