SBH80 stopped working

[Yulan]

After the upgrade, stop working bluetooth headphones. I SBH80 bluetooth headphones, the sound goes well but the problem with the microphone. With regard to the other party, I hear it well and my aponenta not hear me or hear me ragged, torn from my phrases. It all started happening after the upgrade, before it was all good. Tell me what should I do? Or fix this problem in the update
