Xiaomi 1 1Ultra video information does not vibrate.

Because the ringing mode vibration or the mute mode vibration is turned off.

Open the phone settings button, find the sound on the settings page, and click Enter. Maybe it's because we turned off the ringing mode vibration or silent mode vibration, turned on the two functions under the sound, and then dialed the phone to see if it vibrates.

There is vibration under the auxiliary function. See if the function is on. If it is closed, please open it. If the mobile phone has the auxiliary function of turning on the dot, turn on the dot and the device, and then cancel the mute mode.
