Camera doesn't work inside Android application yet so no video calls. MSameer said it would be fixed in an upcoming update.

Android picture editing and posting apps like Instagram or XnRetro can access your camera's gallery though.

Audio from youtube and dailymotion videos using their respective Android apps is slightly out of sync. Could other people please confirm this on their devices.

Can't set the phone up as an internet hotspot yet. There are ways of doing this from the command line only at present.
