Care & Maintenance:

1. Oil stains and sweat.

The mobile phone screen is very afraid of the conductive medium of oil and sweat, which will make the mobile phone screen unresponsive or the screen drift when covered on the screen.

Therefore, if it comes into contact with substances such as oil or sweat, it should be cleaned up as soon as possible.

2. High temperature. When the temperature of the surface of the display reaches about 40 degrees, there is a possibility of drifting.

It will reduce the lifespan, so on a high nuclear day in summer, you should try to avoid exposing your phone to the sun outdoors.

3. Magnetic field. If you put a magnet on the screen, you will immediately find that the capacitive screen will temporarily malfunction, and if it takes a long time, it will cause permanent malfunction, so try to avoid close contact between the phone and magnetic objects.

4. Voltage. The working principle of the capacitive screen is that when the finger touches the capacitive screen, it will take away the point current on the screen, and the screen will evenly transmit the current from the four corners to fill the position of the paper press, so in the case of unstable transmission voltage, the effect of drift will appear, so we should try to avoid charging after the power is less than 20%, and should be charged in time.

2. Use third-party software for a white screen.

There are usually three reasons for the white screen of a mobile phone: one is the hardware, one is a software defect, and the other is the operation of the camera phone.

First of all, there is a contact point between the upper and lower cover of the mobile phone, which plays the role of connecting, hanging, closing the inner screen and opening the outer screen. The control of the inner and outer screen is a small bulge above the keyboard, when this small bulge is pressed on the corresponding small groove, it means that the phone is closed, the inner screen is extinguished, the outer screen is ignited, and when this small bulge is not pressed on the small groove, it means that the phone box cover is opened, the outer screen is extinguished, and the inner screen is ignited. If the lid is not tight after using it for a period of time, the small bulge cannot be pressed well to the end, and the outer screen is not bright, and when the lid is opened, the groove cannot be completely up, and the inner screen is not lit, and a white screen appears.

Also, the clamshell machine is prone to a white screen, which is mainly caused by the poor contact of the connected cables, and it will be displayed when it is contacted, otherwise it will be a white screen. In this case, you need to open the re-soldering contacts, if it doesn't work, you can only replace the cable, and if you happen to encounter a cable that is not sold separately, you can only replace it in full screen. There are also some reasons why the screen does not display is caused by the motherboard, mainly due to damage to the circuit and power chip, which causes the display to not be able to supply power.

If you can't eliminate the fault after opening and closing it a few times, but after shutting down and turning it on, it can solve the problem, then it can be roughly regarded as a software problem, and you should go to the repair center to test the mobile phone and repair it.

In addition, some camera phones appear white screen phenomenon when taking pictures, then it may be caused by improper adjustment of **degree, that is, consumers adjust the **degree to +2, because ** is too high, then the screen will display white. In this case, it can be solved by lowering the ** degree, and it is not a problem with the quality of the mobile phone.
