Facebook announced profile videos a couple months back, showing off the ability to play a moving picture when people first begin the page stalking process. This one minute video gives you an idea what to expect, minus the graininess that comes from using your phone's less than stellar front-facing camera.
These videos, which totally aren't GIFs, are 7-second loops that include sound. They autoplay by default, but users have to tap on the video to pull up the sound.
It appears this feature is now making its way to Android. Readers are seeing a reference to video profiles appear in the Facebook app when editing their profile pictures. A pop-up (pictured above) shows that profile videos are rolling out slowly and that Facebook will inform you when the feature is ready.
Profile videos are rolling out alongside other significant changes, such as the ability to set temporary profile pics, pin a featured photo to the top of a profile, and more prominent profile photo placement on mobile devices.
