For this problem, you can refer to the following information:
1. The working principle of this function is to rely on the acceleration sensor in the watch. You can wake up the screen by tilting your wrist, such as turning your wrist or raising your wrist. However, if the wrist turning angle is too small and the speed is too slow, it will cause the screen to fail to light up;
2. The over-low battery power will lead to this function not working, if so, please try again after charging it to a normal battery power level;
3. Please press and hold the power button for 12 seconds to force restarting the watch. After restarting, please check the version of your watch and update your watch to the latest version.
