Why can't Samsung zflip3 small screen recorder be used?

1. Check whether the third-party software is newly downloaded and installed on the mobile phone. It is possible that the software is incompatible with the mobile phone, so I suggest you try to uninstall it (Settings-More-Application Manager-Select Download-Uninstall);

2. If it doesn't return to normal, I suggest you back up your mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings (Settings-Account-Reset-Restore Factory Settings);

3. If the problem still exists, it may be that there is something wrong with the software of the mobile phone system. It is recommended that you take the mobile phone three-guarantee certificate to the nearest Samsung service center for testing, but professionals can solve the problem.
