How to turn up the volume of Xiaomi mobile phone?

Method 1: Facing the screen, there is a long volume adjustment key on the right. Press the top half to increase the volume and press the bottom half to decrease the volume. Generally speaking, if you don't lock the screen, you just adjust the volume of the bell. If it is in the playback mode, it is to adjust the volume of the media player, and there will be a volume progress bar prompt on the screen.

Method 2: In the system settings, there is a "sound and vibration" option, which can set the volume of various sounds.
