I have an Xperia S and the phone pairs with the Mercedes Benz (B200) Comand APS automatically, right from start-up. However, the first time a call is received after connecting, the caller cannot hear anything; I can hear them. The problem is inconsistent. If I make the first call the connection is, usually, okay and both parties can hear each other. Subsequent calls are generally okay from that point, but inconsistant.
Sometimes after answering a call, if I switch the bluetooth off on the call screen, tell the caller to hold on, then hit the bluetooth button on the call screen again, the call is usually fully enabled both ways. This is also inconsistant. As expected, Sony have told me it's the car, Merc tell me it's the phone. Typical.
I like my Sony Smartphone but may have to go to another manufacturer's compatible phone as the phone problem is dangerous at worse (while driving, and illegal to touch the phone) and unprofessional/rude to clients in the least.
Is there a patch, or fix or update available? Sony Support please?
Regards, John
