Spotify stops all of sudden when I do other activities on phone.

[user-removed]

When I play any song, and open other apps or just stay in main screen, the app stops more than 90% of chance all of sudden. And it even didn't stay where it played the last after stopping, song starts from the first if I push play button again. I think my mobile keeps closing the app in the middle of something? I want to ask that to spotify programmers but I can't find any menu to send email to Spotify directly.
Anyone knows the solution, or the way to report this bug to Spotify?
Thanks.
