Which device you have?
so I tried this and its working in Lumia 920 as well , but these are not live images ?you have to take pics with smartcam mode or cinemagraph,, going to the new camera roll from the nokia camera beta, then, you will see the living images
Any images you’ve taken using Nokia Cinemagraph and Nokia Refocus, including any videos, will also appear as Living Images in your Camera Roll and will be momentarily brought to life as you thumb your way through them..
Working on my 1020 too… but it's so annoying! I don't want it to force taking living images all the time. And then when you browse your gallery inside Nokia Camera Beta, the image will be moving… I don't like it. It's fine if you took the pics on purpose for this feature, but not when you just want something steady. Also I have the feeling that now taking a picture takes longer… when you do, it says "Saving living images…" so the whole experience now feels slower
