What's new

• Duetto now works as a call, like WhatsApp; before it was a different kind of app.
• Two separate buttons, microphone and listening.
• Bluetooth headsets: each device remembers whether it takes the sound by itself; its battery level is in the button.
• The other connections stay reachable even when not in use.
• The screen without video shows with icons the microphone and output, yours and the other person's.
• And various other minor improvements.
