1. I have fallen, or I have fallen not long ago, the screen touch screen has been loosened, and after a period of time, the wiring will fall off directly.

Second, if it has been flooded, it can be used again when it is dry, as if it is fine. In fact, the motherboard must be cleaned, otherwise the circuit will rust and there will be problems after a period of time.

3. High imitation charger and charging cable. Many people give off the bag when they buy it, and when they get it back, it is a high imitation, and after using it for a while, it hurts the power supply. Directly scrap the phone, especially the Hong Kong version of the mobile phone.

Fourth, charging while playing with your phone will also hurt your phone. Sometimes the current is too high and burns the inner screen.

Is there any way to fix this, check it, if the line is loose, change the line. If the inner screen is broken, directly replace the screen assembly.

If you change the screen, it is not good, it is the touch screen IC problem of the motherboard, the so-called touch screen IC is a chip that controls the touch screen, which can be replaced, but the process requirements are very high, this is a chip-level maintenance, and the general small shop will not. Only contact the after-sales center for repairs.

Hope it helps.

The phone's touch screen may be caused by a phone crash. 1. The phone is overheating. Whether you need to use your mobile phone for a long time for work, or use your mobile phone for a long time for entertainment, or if you leave your mobile phone outdoors for too long, the mobile phone will be particularly hot because of the long-term operation, and the overheating of the mobile phone will not only damage the battery, but also greatly reduce the sensitivity of the mobile phone screen.

2. Static electricity problems. When the general mobile phone is in use, we will paste a tempered film, the reason for this is that we can avoid accidentally dropping and breaking the screen of the mobile phone, especially the inner screen of the mobile phone. However, the tempered film is also good and bad, if the quality of the tempered film is not good, it is easy to produce static electricity, which will have an impact on the touch of the mobile phone screen, causing the problem of screen failure.

3. There is liquid on your hands. Many friends like to take their mobile phones with them when they are cooking or washing clothes, generally cooking or washing clothes, and generally chasing dramas, and at this time, if there is water or oil on their hands, when they touch the screen of the mobile phone, the mobile phone screen will not work or fail.

4. The charging voltage is not fixed. After using the mobile phone for a period of time, whether it is because the charger itself is broken, or accidentally lost, many people will choose some non-original and relatively cheap chargers to charge the mobile phone, and at this time, if the mobile phone is not charged with a fixed voltage, the screen of the mobile phone will appear here and elsewhere but there is a response or no use.

1. Static electricity causes temporary screen failure.

1. Wipe the screen several times with the whole palm of your hand, which can remove static electricity to a great extent;

2. If method 1 is invalid, you can also try to press the physical key first, and then slide to answer;

3. If it still doesn't work, you can wipe the screen with a dry damp cloth, so that the water will take away the static electricity;

4. There is also a very simple way, that is, the transparent tape is glued, and when the tape is quickly uncovered, part of the charge will be taken away.

Second, the software causes the mobile phone to crash and fake death.

2. Press and hold the power on/off button to restart the phone; For some mobile phones with the home button, long press the "home button + power on/off button" which is a forced restart and turn off the phone, which also helps to get out of the dilemma of screen failure.

3. Failure caused by damage to system files.

4. Hardware damage leads to touch failure.

After the mobile phone is dropped or liquid is entered, the LCD screen cable is loosened, and the touch IC is corroded, and these hardware damage will cause the screen to drift and the touch to fail.

If the phone is disobedient, it's good to drop it, it's better to drop the screen so that you can change the screen, or you can just blow it up, and then replace it with iPhone 12

If you are consulting an Honor phone and your phone has a touch screen failure, you can follow the following methods to troubleshoot:

1. In order to ensure the accuracy of the investigation results, please ensure that the following are made before the investigation:

1. The surface of the screen is clean, there are no oil stains, water stains, etc., and the presence of liquid on the surface of the screen may cause the touch screen to jump and be insensitive.

3. There is no high-intensity magnetic field such as microwave oven and induction cooker nearby, and the high-intensity magnetic field will cause interference to electronic components, resulting in abnormalities such as random jumping of the touch screen.

4. In winter, the outdoor temperature is low and the indoor temperature is high, after entering the indoor from the outside, the indoor water vapor will liquefy when cold, and there will be a layer of water droplets on the mobile phone screen. It will cause the touch to be insensitive and unresponsive. It is recommended to wipe the water droplets on the surface of the mobile phone before using the touch operation.

5. Please confirm whether the charger is the standard charger for Honor, if you use the touch screen while charging, the power supply voltage may be unstable, which will greatly interfere with the touch screen, thus affecting the touch screen experience.

(When the hand is in direct contact with the mobile phone, it can ensure that the human body and the mobile phone are connected, which can reduce the effect of interference).

6. The film should not be too thick, otherwise it will affect the sensitivity of the touch screen, and it is recommended to replace the film with a thickness of no more than millimeters or replace the official protective film.
