I've had this issue with the last couple of phones I've had where Bluetooth will periodically stop working with my cars infotainment system. Bluetooth will randomly disconnect audio only, but still connects for calls. Re-pairing, restarting the phone, and resetting the infotainment system does nothing to fix this.
This has also happened with multiple cars, seems to be completely random, and lasts a few weeks, before randomly starting to work again.
After googling this appears to be a Samsung issue. I'm now 6 months into my new contract and the really don't want the have to put up with this for another 18 months. I regularly use Bluetooth in my car for music and navigation, so without audio it's useless
Is there anything that can be done?
