Why can't I open the software downloaded by Coolpad mobile phone? What should I do?

1. Close and restart the application.

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

3. Try to replace other versions.

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.

7. If all the above methods fail, it is recommended to send the mobile phone to the nearest service center for testing and further processing.
