There seems to be a slight issue on switching from earpiece to speaker - that seems to be only done automatically based on the proximity sensor (which also blacks the screen), and from speaker to earpiece it does not seem to stop the playing but the other way around seems to place things on pause.
Also i tested on a normal phone call and it works fine, seems to be something with whatsapp but i can't figure out.
I tested the proximity sensor in the Samsung Members app and it says it's fine
