Why does my Xiaomi 1 1 Youth Edition screen often fail?

If some clicks on the touch screen of your mobile phone are unresponsive, the touch screen is broken or the touch screen is out of order, we suggest that you troubleshoot in the following ways:

1. If someone damages the mobile phone screen (such as cracks or water), I suggest you go to the after-sales service in time;

2. Non-original film may affect the sensitivity of touch. I suggest you change the official film as much as possible;

3. Using a non-original adapter during charging may cause abnormality due to voltage problems;

4. Enter * # * # 6484 # * * in the dial-up interface to enter the hardware detection mode, click "Touch Screen Test", and slide your fingers on the screen in the following order:

The rectangle around the diagonal of the screen-the cross in the middle-slides from where there is an X to where there is an X on the diagonal.

Test the touch screen to see whether the sliding line is broken and whether there are redundant lines in the non-sliding line area;

5. The virtual key problem can enter the hardware detection mode "key test", and "menu"/"return" are all virtual keys, so whether the key can be successfully tested;

6. If you enter the hardware detection mode, the test fails or the calibration fails, it is recommended that you update to the latest MIUI version and resume the factory trial.

7. Some curved screen models have the function of "preventing the edges from touching by mistake" in the settings to prevent the surfaces from touching by mistake. You can search in the settings, enter this option, and select or customize the error-proof operation mode suitable for your usage habits.

8. If there is water on the screen or fingers, it may affect the touch experience.

9. If the above methods are ineffective, it is recommended to conduct after-sales inspection.

Supplementary note: Due to the characteristics of the capacitive screen, if the contact point of two fingers is too close, it will be recognized as a point.
