My Z1 suddenly lost the headset connection and not recognize it anymore, few reboots and clearing data of SmartConnect take no effect on this issue.
With the simple headphones phone works fine.
I also tried SoundAbout to manually reroute sound to headset and it work! But it's not normal fix on issue.
How do i fix this issue? Did I need to take my phone into the service?
P.S.: Sorry for bad English.
You could boot on safe mode or repair the phone with PCC but it seems that you should contact your local Xperia Care
