Before you start
Do not begin with a broad reset. Check the following first so you can isolate the problem and avoid unnecessary data loss or reconfiguration.
- Check whether the service itself is experiencing an outage
- Determine whether important data exists only inside the app
- Make sure you can sign in and complete two-step verification
Critical diagnosis for this symptom
Check whether one app or multiple apps fail and whether the issue followed an OS or component update.
Confirm sign-in and sync status before clearing data or reinstalling.
Escalate with device, OS, error, and reproduction details when the issue persists after restart, controlled comparison, and update checks, or when physical damage, abnormal heat, account suspension, or carrier provisioning is suspected.
Understand the process
Safe step-by-step procedure
Work from the top and stop as soon as the issue is resolved. Read every confirmation screen before moving to a higher-impact action.
- 1Force-close the app and open it again.
- 2Restart the phone.
- 3Check for an app update in the official store and for an OS update.
- 4Review free storage and required permissions such as camera, photos or microphone.
- 5On Android, clear cache using official steps where appropriate; clearing app data is different and may remove local information.
- 6Before reinstalling, confirm account sync, backups and any transfer code.
Actions to avoid
- Installing an old or modified app from an unofficial source
- Treating Clear Data as equivalent to Clear Cache
- Deleting an authenticator app without transferring accounts
Prevention and preparation
- Check sync status in important apps regularly
- Store recovery codes securely
Frequently asked questions
What if my screen looks different?
Labels and locations vary by OS, manufacturer, model and region. Use Settings search and check the manufacturer’s model-specific instructions.
What if I am unsure partway through?
Go back and confirm that no action has been committed. Do not proceed through an erase or account-change warning until you understand it.
What if the problem remains?
Test another connection or accessory where relevant, verify backups, then contact the manufacturer or carrier through official support.
