What should I do if Huawei's mobile phone touch screen fails?

Check whether water, sweat and dust on the screen will affect the touch response of the screen. Please wipe your hands and mobile phone screen before trying to use it.

Too thick screen film will affect the screen touch sensitivity. It is recommended to replace the film with a thickness not exceeding 0.2 mm.

Non-standard charger and data cable are used in the charging process. The interference shielding ability of non-standard charger is weak, which will affect the touch screen function of mobile phone. Please use the standard charger to charge.

When using a mobile phone, there is a strong electromagnetic field (microwave oven, induction cooker, power station, etc.). ), will affect the touch screen function. It is recommended to change the use environment and confirm whether the screen function returns to normal.

When using a mobile phone, abnormal ambient temperature will lead to abnormal screen display and touch function. (Above 50 or below -20) Please try the mobile phone at room temperature.

Please check if glove mode is on. Glove mode will improve the sensitivity of the touch screen. If not, it is recommended to turn off this mode.

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

If you can't get back to normal by locking the screen, waking up the screen or restarting the mobile phone, please take the purchase invoice to the after-sales outlets for repair.
