Why does Samsung 9300 mobile phone automatically send a text message saying that I am in the cinema?

1. Check whether the third-party software is newly downloaded and installed on the mobile phone. It is possible that the software is not compatible with the mobile phone, so it is recommended to uninstall (Settings-Application Manager-Select Download-Uninstall).

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

3. If the problem still exists, it may be that there is something wrong with the mobile phone system software. It is recommended to send the mobile phone to the nearest Samsung after-sales service center for testing.
