The Asus-made Google Nexus 7 might be the go-to Jelly Bean tablet (or even device, at the moment) since it’s part of the Nexus family but it is lacking a main camera at its back. The reasons could be multiple, from usage habits to reductions of costs, but the reality is that there is just one front facer which is one of 1.2-megapixels.
This webcam is capable of recording 720p video just fine, just not out of the box. If you apply this XDA Developers mod you can enable it by simply adding the video profile, which is missing, to media_profiles.xml. There are a couple of ways you can achieve this so if you’re interested head over to the source link below and check out the instructions. Given the fact that the camera on the front of the device is not a high-end one, don’t expect stellar results; however, there is visible improvement compared to 480p videos.
Oh, in case you were wondering, the Nexus 7 is perfectly capable of snapping pictures and recording video. It has everything necessary to do it but it is lacking a camera launcher which you can easily fix by grabbing one of the launchers on the Play Store.
