Frequently asked questions about Xiaomi phones.

4. Send the mobile phone to the after-sales service for upgrading.

5. After restarting, the scheduled shutdown can be canceled.

Three. The body is hot or hot.

Reason analysis: A smartphone is quite a miniature computer, and the CPU will generate heat when it is working (but the mobile phone does not have a special heat dissipation device like a computer), and the heat is dissipated through the shell, so we will feel that the body is hot, which is normal. When playing large 3D games or charging the phone, the heating phenomenon is more obvious.
