The phone suddenly can't connect to sync. What happened?

There is a problem with the third-party application downloaded and installed by Samsung mobile phone, and it 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 to change to another version.

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

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

6. If it still can't be used after returning to the factory, other third-party software can be used normally, and only this software can't run normally. This 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.
