Another one with the same problem, here in Spain. I used to go to sleep every night listening to Spotify music at a very low volume, but with the annoying hiccups in the sound from the speaker I had to quit doing it. I think it's a considerable flaw and I can't believe Samsung still hasn't addressed it. My next phone won't be a Samsung for sure.
Nothing have been solved, first time i have purchased a samsung phone and happens the same thing of which i was afraid. Worst brand ever... i am a music lover but can't listen the songs on my smartphone while travelling and sleeping because of annoying voice in earphones.
Great news all!
The November security patch update has FIXED the sound cutting issue. Samsung specifically fix it and state it in their changelog. I have tested it, 100% battery, no stuttering whatsoever. It's finally fixed!
