Mobile phone hangs in music app?

I have a really annoying problem here, whenever I connect my jbl charge 3 box via bluetooth to my huawei p8 lite 2017, the music app hangs, songs start to hang, but if you run a playlist and not between songs and her zapt, then it does not lie after a few minutes. Can someone help me?

You could do a backup, reset the phone test and if it goes look why and if not the backup back on it and hope that there's a new update.
