Motor damage
If the motor is damaged, the cover cannot be opened automatically in any case, and the motor needs to be replaced at this time.
Sensor problem
If there is something wrong with the sensor, you need to check whether the sensor is dirty or damaged. If it is dirty, you can clean it with alcohol or cleaning solution. If it is damaged, the sensor needs to be replaced.
Touch the key by mistake
There are also some users who may touch the keys by mistake during use, resulting in the failure of automatic cover opening. In this case, just turn off the key.
Contact customer service
If the above methods can't solve the problem of automatic opening, it is recommended to contact Xiaomi's official customer service for help, so as not to cause more losses.
