Ok, I have been wanting this feature to exist for 5 years or so:
4K video at 120 fps, and if I’m lucky maybe even 4K at 240 fps or 480 fps way down in the future.
Because brag all you want with Sony’s 720p 960 fps or Samsung’s 720p 960 fps (in short bursts) (and motion activated). Until you go 4K Slow-Mo, it’s going to keep looking the same. 4K slow-mo video, like Gavin Free’s The Slow-Mo Guys, in a phone, would be a game-changer, and iPhones or other Android phones would really show off the real ability to be a mobile powerhouse.
