Nexus Q updated, now works with Android 2.3.3 or higher; updates for YouTube, Play Movies & TV
The other updates involve YouTube and Play Movies & TV. The YouTube app has been updated to allow it to send content to Nexus Q and to be used as a remote to play videos on other devices when used with an earlier Android build. The update to Play Movies & TV makes downloading from the app faster while it also kills off some bugs and improves performance.
The trio of apps are all free and all available from the Google Play Store now.
