Tablet cameras generally don’t live up to their potential. There are a variety of reasons for this, but most notable is that people don’t often use the camera on a tablet. A tablet is too big and bulky to be used as a camera under most circumstances, so OEMs generally don’t put much work into camera software.
That said, this doesn’t mean that the actual camera units themselves are worthless. Rather, they can often be modded to produce better content. Such is the case on the Google Nexus 7, which can now record video at 720p. Installation is simple, requiring that users edit their media_profiles.xml file.
While a flashable zip will most likely come in the future, it’s fun to edit the file manually. XDA Recognized Developer hillbeast who created the guide, includes before and after videos.
