Thanks i have checked that, both speakers are working but just not very loud anymore. To be honest i think I'm going to add sell the Robin. After using my old S6 again the camera and screen are so much nicer than the Robin i don't know if i can go back.
I've been on Nougat for a while now and I'm having the same issues. On occasion the volume will be just as loud as it previously was, then if a video/song is paused, or stops due to buffering, it causes my audio to drop again. It's quite the pain
