A front-facing camera, or selfie camera is a common feature of cameras, mobile phones, smartphones, tablets and similar mobile devices that allows taking a self-portrait photograph or video while looking at the display of the device, usually showing a live preview of the image. Front-facing cameras are therefore an important development for videotelephony and the taking of selfies.
