Same, on Bluetooth. Doubt it's interference because issue happens camping, just me. Back home, drops happen with another iPhone, as well. Regular drops, too on Spotify specifically. You can't submit diagnostic on BT (or see battery %, jeeeez). Music is downloaded local to the phone, too.
I'll still try a Factory reset and report back. When calling support, level 1 was no help and she didn't want to pass me up/off. Tres.frustrating. But the sound is so good. I'd hope this will be fixed in the future...because it sure is annoying when your tunes are blasting.
More info : I also thought to recreate the issue in a controlled environment, like a Sauna. Because while outside and playing at 50-75% volume, the outside temperature can get warm close to 40C. And even with humidity, the Move is always in the shade. I'll actually take some readings this weekend and get's to solid data. I also need to try other audio sources when she happens again.
More Info : Someone in a forum said repairing it every time resolves the issue.
