The mobile phone will automatically send some inexplicable text messages. Is it the mobile phone?

The mobile phone automatically sends text messages. This problem may be related to the software used. Suggestions:

1. If text messages are automatically sent after opening a certain software, it is recommended to check the software settings. Is there any calibration setting content, such as calibration flow rate, etc.

2. Try restarting the phone.

3. Place the mobile phone SIM card in other machines to observe whether the same problem occurs and rule out whether it is related to the SIM card binding service.

4. If text messages are automatically sent only to this phone, please back up the data in the phone (contacts, messages, pictures, etc.) and try to restore the machine to factory settings.

If the problem persists, please bring your purchase invoice, repair card and machine to the Samsung Service Center for review and resolution.
