Nokia Lumia 800: when screen goes black, Skype does not play any ringtone anymore.
So basically it's useless for incoming calls, there's no visible or audible alert at all...
Working on HTC 7 Trophy with 8107 update.
Voice and video works, but voice only goes through loudspeaker, the toggle doesnt work.
Using bluetooth headset the voice data becomes choppy and useless, although using earphones are an alternative as earpiece speaker.
Hoping for the final release.
