Can the Redmi Watch 4 control the phone to play music?

The Redmi Watch 4 can control the phone to play music. To use this function, the phone and the watch need to be connected and the right to use APP notifications need to be turned on.
You can open the music player on the mobile phone. After starting to play music, enter the function list on the watch and select the music icon to enter the music control page. You can start/pause music, switch to the previous/next song, and increase/decrease the volume.
Note: 
The Redmi Watch 4 supports most music players on the market, but due to differences in the openness of music players and APP versions, the experience of the watch’s music control function will be affected to a certain extent. (There will be some compatibility issues when controlling the third-party music players with your watch on iOS.)
