Just wondering if anyone else has the same issue as me..
Phone calls connect but then you can not hear the other party. Doesnt matter if via headphones or not.
Also noticed the phone app becomes unstable at the same time so its hard to end the call.
I managed to find the offending setting:
Goto General/Accessibility/Call Audio Routing and select "Automatic".
In previous iOS versions I had to set this to "Bluetooth headset" to correctly route the audio to my Belkin Bluetooth car kit.
As it may happen, Apple actually might have fixed a bug since one would expect that the correct setting should be "Automatic" all along.
I didn't try using my Car so we may need to toggle this everytime we go in and out of the car.
Hope this helps.
