What if Samsung smt2 1 1 app doesn't work properly?

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

2. Try to change to another version.

3. Update the mobile phone system version and then try to install it.

4. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ), restore the factory settings and then try to reinstall.

5. If it still can't be used after returning from the factory, other third-party software can be used normally, and only this software can't run normally, which is the compatibility problem of the mobile phone system.

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