After the last update to "jellybean" my headset stopped working. My radio asked me to "plug in headset as cable works as antenna", even with nye headset plugged in. The headset worked fine before I upgraded, and it still works on other devices. No other headsets I tried works on my Xperia, so it is pretty clear that this problem has to do with the upgrade. Is there anyone who can help me, I would be very grateful, as I am unable to Google-fix this.
