My mobile phone cannot be authenticated, what should I do?

There is a problem with the third-party application downloaded and installed on the mobile phone and cannot be used normally. It is recommended to follow the following methods:

1. Close and restart the application.

2. It is recommended to uninstall and reinstall the software.

3. Try changing to other versions.

4. Update the phone system version and try to install it

5. Back up the phone data (phone book, text messages, multimedia files, etc.), restore factory settings and try to install again

6. If it still cannot be used after factory reset, and other third-party software can be used normally, but only this software cannot run normally, there is a compatibility issue with the mobile phone system.

It is recommended to send the phone to the nearest service center for testing and further processing
