The Xiaomi Pad 7 is equipped with a highly sensitive Hall sensor to support the automatic wake and sleep functionality of accessories like the keyboard cover. This sensor detects the magnetic field when the device is closed, triggering the screen to turn off for power-saving purposes or to activate sleep mode. However, if a magnetic object such as the Xiaomi Focus Pen, keyboard cover, stand cover, phone speaker, or even a radio is near the Hall sensor, located near the volume buttons, it can interfere with the sensor's normal operation, causing the screen to turn off unintentionally.
Note:
Using the Xiaomi Focus Pen, keyboard cover, or stand cover as intended will not cause this issue, so please rest assured to use this device.
