Why can’t I hear any sound other than speaking when the Xiaomi 15 Ultra is on a call?

In order to ensure that normal calls are carried out smoothly without being disturbed by noise, the algorithm will give priority to the smooth transmission of human voices. Of course, if there are special needs, such as the transmission of background music, the noise reduction algorithm can be turned off.
Operation method: Swipe right on the call interface to open the call toolbox and cancel the audio noise reduction algorithm.
Thank you for your support of Xiaomi products. The Xiaomi 15 Ultra has undergone strict professional inspection before leaving the factory, so you can use it with confidence.
