Lumia 920, bluetooth issues

Hey guys,

I am seeing a real weird issue with my lumia 920.

Whenever I use Bluetooth (in car or headphones) after a while the sound kinda dies, it's still connected to the paired device, but the sound is now extremely low ( close to none).

Its doesn't die always, but its frequent enough to bother me. Especially when I am on a call while driving.

Only way to fix this is to reboot the phone. Is anyone else seeing this issue ?
