I think the galaxy 10 was made too quickly...i heard several people having issues with theirs. I have a 9S note...no issues at all
Same here but it was my own fault as I had restricted the background use and data of Spotify. After changing that has been fine
Same happens to me with J7 using Pandora or YouTube. Hope someone has a solution.
Another solution which I found by accident , under battery usage, click on the app that keeps cutting out, there is on option "allow backgroud activity " make sure is turned on.
