Why does the screen on/off function of the Xiaomi Pad 7 Pro completely fail when using a third-party leather case?

The screen on/off function of the Xiaomi Pad 7 Pro could completely fail when using a third-party leather case due to interference with the Hall sensor. The Hall sensor is responsible for detecting magnetic fields and is commonly used in smart cases to automatically wake or put the screen to sleep when opening or closing the cover.
This device also features a cooling back clip function, and certain third-party cases can unintentionally interfere with the Hall sensor, causing false triggers or preventing it from functioning correctly. As a result, the tablet can fail to automatically turn the screen on or off, affecting the overall experience.
To ensure optimal performance and avoid such issues, it is recommended to use the official Xiaomi case, which is specifically designed to be compatible with the device’s sensors and features.
