Why does the Xiaomi Watch S3’s smart display dial not turn on automatically?

Question

Accepted Answer

After smartly turning on the always-screen dial, the always-screen display will automatically turn off when you fall asleep or take off your wrist. After waking up, the screen will turn on for the first time (raising your wrist to turn on the screen, pressing a button to turn on the screen). Only when you turn off the screen again the always-on screen dial can be displayed normally.
