The reason why the screen has garbled code or black and white lines is that the user's phone has a software fault or the LCD on the display screen has a fault. The responsibility of the battery is to store and provide electrical energy, which results in insufficient standby time, short talk time, and so on. The poor performance of the protection board circuit indicates a failure of power failure. Neither of these will cause screen defects.
