A strange phenomenon occurred during the use of my Xiaomi 11. It vibrates every morning at o'clock on time, lasting for more than 5s. But there is no notice on the phone screen, and of course I have not set the alarm clock for 6:00. The article originates from the fallen fish- https://www.duoluodeyu.com/2645.html
Later, after being instructed by a senior person, it was found that it was caused by setting the Do Not Disturb mode on a regular basis. The My Do Not Disturb mode is set at 23:00-6:00 every day, and all mobile phones will vibrate when they exit the Do Not Disturb mode at 6:00 every morning.

If you don't want your phone to vibrate at this time every day, you can adjust the time when Do Not Disturb mode is turned on regularly, or you can turn off the time when Do Not Disturb mode is turned on regularly. The article originates from the fallen fish- https://www.duoluodeyu.com/2645.html
