I received my nexus 7 yesterday and attempted a video skype call. The quality was so bad as to render both parties unrecognizable and since we've been married for over 40 years that seemed a bit strange. I downloaded the camera app this morning and it took a very respectable pic. Since the other device was used for a skype video call to a Mac and looked fine, it seems that it must be something about skype on this device - and yes, I know that it isn't skype certified yet. I also heard on one of the podcasts that this was an issue. Has anyone else tried a Skype video call? Results? Suggestions?
