Dear Samsung users:

Based on your description, we recommend that you:

1. Try switching the phone on and off again

2. Uninstall the recently installed third-party software and observe to initially rule out whether it is a software conflict, such as mobile phone manager, games and other software.

3. Back up mobile phone data (phone book, text messages, multimedia files, etc.) and restore factory settings (enter phone settings--Reset/Privacy/Private-Restore factory settings)

If the factory reset problem persists, it is recommended to send the phone to the nearest Samsung service center for testing and further processing.

For the service center address and contact information, please visit:
