For those looking to fully utilize that little front-facing camera on your Nexus 7, developers over at XDA released a flashable zip file to allow for 720p video recording. This is for users rooted and running a custom recovery. By editing a media_profiles.xml file, they have allowed for 480p and 720p HD recording. To install, once you download the zip file and place on the device’s storage, just boot into recovery and flash from there.
