Ok, I'm not buying it. First I've watched several videos showing setup of the S10 FPS and more than a few have mentioned that the S10 takes 16 images to create one set. In the setup the user alternates between left and right thumb to create one image that enabled them to use either thumb. If this video were really true why didn't they open the device 3 or 4 times with different fingers and or thumbs? Then the cut scenes are actually cuts and not zooms. If they'd opened the menu and zoomed in as one continuous shot it would have been more believable. I call BS and I'm not even going to mention that this is from Sun News.
Unfortunately those tricks are within other tips and tricks videos and I'm not watching twenty 20 minute videos to find the two that show users doing this.
