The screen doesn't light up after you tap it twice on the Redmi 12
If the screen doesn't light up after tapping it twice on your Redmi 12, you can try the following troubleshooting steps to address the issue:
1. Ensure that your phone's operating system is up-to-date. Software updates often include bug fixes, security patches, and improvements that can address software-level issues;
2. Check if the feature is enabled by going to [Settings] >> select [Always-on display & Lock screen] >> look for [Double tap to wake or turn off screen when device is locked] >> ensure it is enabled;
3. If you are using a screen protector or a case, it might interfere with the proximity sensor or the touch sensitivity. Try removing the screen protector or case and see if the issue persists;
4. Restart your phone to refresh the operating system;
5. This feature depends on the touch sensor. Check if the touch sensor is in good condition by going to the [Phone] app and inputting *#*#6484#*#* or *#*#64663#*#* to enter the hardware detection (CIT mode). If the hardware test fails, please contact our local official service center or your seller for further assistance. They will help you in this regard;
6. If the issue persists, you can consider performing a factory reset and try again. Please note that this will erase all data on your phone so remember to back up important information before proceeding.
However, if there is no hardware issue, we hope you could submit user feedback by going to [Settings] >> [Services & feedback], and wait for the future updates.
