Page warp becomes but a tiny part of the problem with a page-flip video – now you have motion blur, varying exposure, resolution, noise, and depth of field to worry about. Maybe if you had a camera capable of recording extremely high frame rates at high resolution (probably north of 120fps @ 1440p), a high-intensity, diffuse light source, and a lens with a tight aperture / narrow focal length, you’d at least have something to work with.
I haven't heard of a phone camera that can do video at 120fps, they're usually 30, maybe 60 fps. The S7 has some high framerate slow-mo option, but it's limited to a 720p resolution.
