Bluetooth audio volume and quality
Hi everybody,
I have an issue with my iPhone 5 using a Parrot Mini Kit Neo 2 HD Bluetooth handset. When I purchased it one year ago I had iOS 8 installed and everything worked properly. Now after few months, probably after an iOS update, currently I have iOS 9, I don't manage to adjust the volume of the device during a phone call, but much worse the quality of the audio during phone calls has dramatically decreased. No problem, instead, with Google Maps voice indications.
Basically, when I press +/- buttons during a call the bluetooth audio level bar on the screen changes but not the volume of the device and I think this affects the audio quality too, like if the output volume is too high to have enough quality. I also updated the device firmware but no results.
Any suggestion?
Thanks
