How is it that the mobile phone automatically sends short messages and sends a bunch of random codes?

Mobile phone sends text messages automatically, which may be related to the software used. Suggestion:

1. If automatic SMS sending occurs after opening a software, it is recommended to check whether there are calibration settings in the software settings, such as calibrating traffic.

2. Try to restart the phone.

3. Put the mobile phone SIM card in other machines, observe whether the same problem will occur, and rule out whether it is related to the SIM card binding service.

4. If you only send SMS automatically in this mobile phone, please back up the data (contacts, information, pictures, etc. ) and try to restore the machine to factory settings.

If the problem still exists, please take the purchase invoice, maintenance card and machine to Samsung Service Center for inspection and handling.
