All the information on the mobile phone is blank, and then it is blank, and nothing can be received or sent.

There is something wrong with the SMS function of Samsung mobile phone. We suggest the following actions:

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

2. If the problem still exists (caused by third-party software), please back up the data of the mobile phone (phone book, SMS, multimedia materials, etc.). ) and try to restore the phone factory settings (Settings-Reset-Restore Factory Settings).

If the problem still exists, it is recommended to bring three purchase vouchers and send the mobile phone to the nearest Samsung service center for testing.
