Samsung note4 mobile phone sent short messages incorrectly, and wanted to cancel all the sending. How to cancel?

According to your description, we suggest that you:

1. Under mobile phone operation: Settings-Application Manager-Slide Screen Option (All)-Find Information-Click Enter to try to clear the data.

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

Note: all the data stored in the mobile phone is lost, so it must be backed up to the sim card and sd card in advance before operation.
