The POCO pad has undergone strict professional inspection before leaving the factory, so please feel free to use it.
The screen will produce a capacitance effect and piezoelectric effect during operation, which will cause mechanical vibration and cause screen noise. This is a normal phenomenon. If you confirm that the noise is caused by cosmetic damage to the screen, please apply to the after-sales service center for repair.
Note:
External electromagnetic interference or internal circuit interference can cause abnormal screen display or noise. Keep the device away from strong magnetic fields and other interference sources.
