Iwatchs8 wakes up and the bright screen flashes.

What do you want to ask is what causes the bright screen of iwatchs8 to flicker? Iwatchs8 wakes up the bright screen because it has built-in accelerometer and gyro sensor and "RaisetoWake" function. When the user raises his wrist, these sensors will be activated, so that iwatchs8 can recognize the action and wake up the screen. At the same time, the flashing cursor on the screen will also remind the user that the device has woken up.
