Common problems and solutions for smartphones:

1. The mobile phone does not turn on: After the mobile phone is placed for a period of time, it suddenly does not turn on. Charge for 10 minutes and then check if it can be turned on.

The all-in-one battery can try to press the power button for 10 seconds, force the power off, and charge for a period of time before trying to turn it on. Some mobile phone batteries need to be charged for a period of time after over-discharge, and the mobile phone can only be turned on when the battery voltage reaches the starting voltage of the mobile phone.

2. Touch screen failure: When charging, when the phone is placed flat on the desktop, or after suddenly taking it out of the pocket, the screen fails and cannot be operated. There may be static electricity on the surface of the screen, and when you press the power button to turn off the screen and then light the screen, the control may be normal.

3. Black screen during call: After the screen goes black during a call, the screen can no longer be lit. Some phones have a proximity light sensing function, and the phone will automatically turn off the screen when the phone is close to the face (saving power and reducing radiation), but sometimes the screen can no longer be lit after the screen is black.

In this case, it is necessary to check whether the surface of the sensor sensor is clean, and in addition, a protective film with poor light transmission may cause the problem of false judgment of the proximity light sensor. (The proximity light sensor is usually located near the handset of the mobile phone).
