Samsung mobile phone automatically replies to SMS.

If the phone automatically refuses to answer the phone, we suggest that you:

1. Please check whether the blacklist function is set on the mobile phone. If yes, please clear the number in the blacklist.

2. Whether the call barring function is set. If so, it is recommended to cancel.

3. If there is software for installing security guards in the mobile phone, it is recommended to uninstall and delete it.

4. If it is invalid, please back up the information (contacts, text messages, pictures, etc.). ) in your phone, and then restore the factory settings.

If the problem still exists, please take the purchase invoice, maintenance card and machine to the Samsung service center, and the professional after-sales engineer will help you test it.
