The multi-function key doesn't work properly (SBH90C)
The multi-function key of the SBH90C currently has some limitations when you try to do the following things:
- Skip to the next music track
- Skip to the previous music track
- Reject incoming calls
- Mute or unmute the microphone during a call
If you use an Xperia phone, these limitations will be fixed in a coming software update.
