The Xiaomi smartphone's screen is turned on by default when we receive a notification, but we can also turn this feature off, in which case the screen remains black and the device only notifies us that we've received a message by means of the notification tone we set.
Note: On Xiaomi devices that support Always On Display, this feature can be enabled independently.
- Open the Settings
- Tap on Lock screen
- Enable or disable Wake Lock screen for notifications
