Steps to be followed if the touch panel is not working in MIUI devices
What should one do if the touch panel is not working? |
Solution: |
1. Please reboot the phone once to check if it helps. If options on the screen cannot be selected, perform a hard reboot by long pressing the power button for a few seconds until it reboots. 1. Check if the phone has any tempered glass or screen protector. Advise to remove it and see if the touchscreen is working. |
2. Ask if the customer is using any gloves, as display will be non-responsive in such cases. |
3. If hands are wet, touch screen will be non-responsive. |
4. Certain non-Xiaomi chargers / cables when connected can make the screen non-responsive or frozen due to current leak. This can also happen when the wall socket has not been grounded properly. Check if this problem is observed only when charger / cable is connected. If this is the case, ask customer to charge using a Xiaomi original charger & cable &/or on a different wall socket. |
5. Perform hardware test after step 4 and check if the test is successful. |
6. If the hardware test fails, ask the customer to visit a service centre nearby and advise to take a full back up before visiting the Service centre. |
