Lock screen function
Swipe down on the watch face page and tap the lock screen icon to enable the lock screen function. After the lock screen is enabled, the watch screen will be locked and no operation can be performed before you tap the Home button to unlock the screen.
If you need to put the watch in your pocket, the lock screen is recommended to be enabled to prevent unintended touch. When you wear the watch to a bath, water droplets splashing onto the watch screen may also cause unintended touch, and turning the lock screen on can solve that problem.
