What should I do if my mobile phone shuts down automatically?

According to your description, if the mobile phone is automatically turned off, I suggest you.

Replace the spare original battery.

If the battery of your mobile phone is low, it will automatically turn off. You can try to replace the spare original battery.

Delete third-party software

If the battery is fully charged, it will still shut down automatically, which may be a software compatibility problem. If automatic shutdown occurs for many times, it is recommended to delete the recently installed third-party software to rule out whether it is related to the downloaded software.

System update

Settings-About Devices-System Update-Update. If the phone has the latest firmware/system version, please upgrade to the latest version.

Restore factory settings

Please back up your data (contacts, text messages, pictures, etc.). ) and restore the factory settings (Settings-Reset-Restore Factory Settings).

Samsung service center

If the problem still exists, it is recommended that you take the purchase invoice, maintenance card and mobile phone to the local Samsung service center for professional engineers to help you test. Please visit:
