There is no flash on the Nexus 7. There is only a front face camera, no rear camera. There is no camera app on it, but you can download it from the Play Store, just search for “Camera launcher for Nexus 7”. Photos and videos are what you would expect from a 1.2MP. Nothing amazing but does take pictures and video if you have lighting where you are shooting. There is no flash.
