If you are using a Huawei phone and the touch screen is out of order, you can troubleshoot it by following the following steps:

1. If your phone screen is dirty or has water stains, it may affect the screen touch sensitivity. It is recommended that you try it after wiping the screen clean;

2. If the screen has a film, it may be due to the protective film being too thick, which affects the touch sensitivity of the screen. We recommend that you replace a thinner third-party protective film or go to a Huawei Customer Service Center to replace an official protective film.

3. If your device is in normal use, the click of a part or the entire screen suddenly does not respond or freezes, please press the power button and the volume up button at the same time to start the screen recording function, and then click the screen operation, if there is a white point on the screen with the finger moves, it means that the touch screen is working normally;

4. If the screen is unresponsive, please press and hold the "power button" for more than 10s, and try to force restart the device, and the failure does not recur, then the phenomenon is not a touch screen problem.

If the above methods still do not solve your problem, we recommend that you back up your important data in advance (QQ, WeChat and other third-party applications need to be backed up separately), and bring your phone, standard charger, data cable, and relevant purchase vouchers to a nearby Huawei customer service center for testing.

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.

2. Do not place it on a quilt, sofa and other soft positions for operation, the touch screen is unevenly stressed, and it will be probabilistically 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.

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. It is recommended that you try not to use your phone while charging, if you must use your phone while charging, please use the original charger, and you can remove the case to improve the touch 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 has the effect of reducing 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.

1. Don't clean up the garbage cache often.

2. The software causes the phone to crash and fake death.

Sometimes after opening an app, the screen suddenly gets stuck and can't move, and the screen doesn't respond no matter how you touch it. This is also a temporary touch failure, mainly because the running storage space is at full capacity and takes more time to load the information.

3. The hardware of the mobile phone is damaged.

Loose screen cables caused by dropped mobile phones, water ingress, and hardware damage can also cause the screen to drift and reduce the sensitivity of the touch screen. If the hardware damage causes the mobile phone screen to fail, it is best to send it to the after-sales service point for repair in time, and do not disassemble the phone at will.

4. Failure caused by damage to system files.

The rooted phone will change and delete the system files at will, which will make the touch function invalid; In addition, the system file may be damaged due to network or other problems during the upgrade, and the touch function will not be accessed.

5. The temperature used is too high.

When the phone is in too high temperatures, the screen is prone to drift. If you are in a high temperature state for a long time, the mobile phone screen will fail or even be damaged, try not to use the mobile phone in a high temperature environment. In addition, if you often use your mobile phone near magnetic objects such as induction cookers, microwave ovens, and stereos, the screen is also prone to temporary malfunction.

6. Static electricity causes temporary screen failure.

When we take the mobile phone out of the pocket or bag, we find that no response is caused by sliding the screen, and we are anxious to look at the caller ID, which is because the mobile phone rubs against the pocket in a dry environment, or is affected by the electric magnetic field, which makes the screen produce static electricity, resulting in temporary touch failure.

If you are using a Huawei phone and the touch screen is partially malfunctioning, you can troubleshoot the problem by following the following steps:

1.If the ambient temperature of your phone is too low, the touch screen may malfunction, which is affected by the physical characteristics of the screen device itself, and it is recommended that you try to keep your phone at an ambient temperature of 0 -35.

2.If the problem persists, we recommend that you bring your phone to a Huawei Customer Service Center with your proof of purchase.

If you haven't backed up your data before, you're at risk of data loss when you detect it.
