Thank you for supporting Xiaomi products. Magnetic sheets have shielding properties, which can interfere with the device’s Hall sensors. This sensor plays a key role in functions such as detecting the stylus, keyboard, and the screen’s wake/sleep function. The Hall sensor works by detecting changes in magnetic fields, so any interference from a magnetic sheet can cause issues with the device's performance, triggering error messages. To ensure optimal performance, it’s important to use magnetic sheets only in the recommended areas. Recommended magnetic attachment areas are carefully selected to allow for efficient heat dissipation while minimizing any potential interference with the device's sensors. Using the device within these guidelines will help prevent errors and ensure smooth functionality.
