What should I do if the touch screen of my Huawei phone fails?

If your phone's touch screen is out of order, you can troubleshoot it by following these 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.

There is a risk of data loss at the time of detection.

This situation is generally caused by a problem with the screen of the mobile phone, usually the external screen or the inner screen will cause this phenomenon, you can go to the mobile phone store to check the specific reason.

No matter how indulgent the environment is, you must be demanding of yourself and maintain a self-disciplined temperament. Maybe it won't change your current situation for a while, but in time, it will surprise you with what it gives back. People who have requirements for themselves will never have a bad time.

People who go with the flow and complain about the bad environment are the most boring.

If you are using a Huawei phone and the touch screen is not sensitive, you can troubleshoot it by following the steps below:

1.If the ambient temperature of your mobile phone is too low, the touch screen may not be sensitive, which is affected by the physical characteristics of the screen device itself, it is recommended that you try to keep the mobile phone at an ambient temperature of 0 -35.

2.If your phone's 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;

3.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.

If the above methods still do not solve your problem, we recommend that you back up important data in advance (third-party applications such as QQ and WeChat must 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.

It is recommended that the landlord restart the phone, if it still doesn't work, it may be that your touch screen is broken.

If the touch screen of Huawei mobile phone fails, it must be a broken screen, and if the touch screen is broken, the screen must be replaced.

If the touch screen of the mobile phone fails, in this case, it is generally the fault of the touch screen, and it is recommended to go to the after-sales service to test it.

The failure of the smartphone screen must be a problem with the dysfunction of the sensor below. I don't think it's easy to solve this problem, because the Huawei phone I use is like this, and I can only use it.

Check that the screen is stained with water, sweat, dirt, etc., which will affect the screen touch response, please wipe your hands and phone screen clean before trying to use it.

If the screen film is too thick, it will affect the touch sensitivity of the screen. It is advisable to replace the film with a thickness of no more than millimeters.

Non-standard chargers and data cables are used during charging, and the weak ability of non-standard chargers to shield interference will affect the touch screen function of the mobile phone, please use the standard charger for charging.

If there is a strong electromagnetic field (microwave oven, induction cooker, power station, etc.) near the mobile phone, it is recommended to change the environment to check whether the screen function is back to normal.

When using the mobile phone, the ambient temperature is abnormal, which will cause the screen display and touch function to be abnormal. (above 50° or below -20°) Please try the phone at normal temperature.

Please check if the glove mode is turned on. Glove mode increases the sensitivity of the touchscreen and is recommended to be turned off if you don't need it.

The new version of the system will optimize some known compatibility issues, and further improve the smoothness and user experience of the system, please upgrade to the latest version of the system to see if the screen operation is optimized.

If the screen cannot be restored by re-waking up the screen through the lock screen or restarting the phone, please bring the purchase invoice to the after-sales outlet for maintenance.
