Note3 is connected to the Bluetooth stereo system. Why can't the Bluetooth audio key control the song change?

Honey, first make sure that the buttons on your Bluetooth speaker are ok. Secondly, make sure that this speaker has a button to switch songs. Then confirm whether it is connected via Bluetooth. If it is a wired connection, the function key cannot be used. Bluetooth speakers can only use function keys when Bluetooth is connected. Another situation is that if your first song is playing, the first time you press the key to cut the song, it will go back to the beginning of the song, and you need to press it again to be the last or the next song.
