My mobile phone always receives two identical messages at the same time. Why?

Samsung mobile phones generally suggest taking the following steps for investigation and handling:

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 service center for testing.
