Little genius's phone watch has a color screen, which may be caused by an error in the watch system. Try to hold down the power button until the watch restarts. If there is no response, it is suggested that you light up the watch screen first, press and hold the power button for 3 seconds, and then press the button for 3 seconds after the pop-up window restarts/shuts down, and select System Repair. If the above operation is invalid, it may be that the watch screen is damaged or there is a major error in the system, and you need to contact the after-sales department to solve it.
