How to break the Samsung mobile phone number when locating it?

It is recommended to try the following methods: 1. Check whether the third-party software (such as 360, Tencent Manager and other management software) is installed in the mobile phone. Please delete such software. 2. Back up mobile phone data (phone book, SMS, pictures, etc.). ) and restore the phone factory settings (enter phone settings-reset-restore factory settings). If the above methods still can't solve the problem, please bring the purchase invoice, maintenance card and machine to Samsung service center, and the engineer will check and deal with the machine.
