The Xiaomi 14T does not support the cover-to-sleep function. Screen covering and dimming refers to the phone automatically turning off the screen or entering sleep mode when you cover the screen with your palm or another object for a period of time. Due to the large size and multi-touch capabilities of mobile phone screens, accidental touches may occur, leading to frequent screen dimming, which may affect your experience and battery life. You can use the normal screen dimming logic to dim the screen by pressing the power button and setting an automatic screen timeout. In addition, the device also supports screen wake-up functions, such as double-tapping the screen to wake up, raising to wake, and AOD (Always-On Display), without affecting the regular screen-off and lock-screen functions.
