Hi all!
I have recently bought a Z1C and pretty happy with it. There is a problem with the headphones (AKG Y-40) buttons, at least with how they work.
It clearly seems like a software problem.
While the headphone is connected via the 3,5mm jack the volume down button takes the volume down to zero, like i keep pressing it. After this none of the buttons work unless I reconnect the headphone or press the phone's volume buttons. Volume up and play/stop works great though until i decide to lower the volume. And the reason for believing it to be software related is that it only happens when a music player (any) is on screen or the screen is off. All buttons work fine when the android desktop is shown, even while playing music. Any ideas?
