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.

The iPhone 6S records 1080p at 120 fps and 720p at 240 fps for their Slow-Mo feature [0].

The iphone 6S can do 120 fps for a short period of time.
