P4 Shooting 1080/120fps is slo-motion straight from camera ?

I tried shooting my friend surfing today in 120 fps and I was a little surprised when playing the footage back later that it was all in slow motion. I thought 120 frames would just shoot more frames and allow for smoother slow motion in post production. Was not expecting the raw files to already be in slow motion...is this a setting I missed or something ? I'm not pro, but I've shot 120 fps in other cameras and it always plays back in real speed. Slow mo must be done in post. What's going on with my Phantom 4 ?

I know when I shoot 240fps on my phone and then watch the video on my phone, it plays back at 30fps, slo-mo. Yet when I edit the footage in Davinci Resolve it is indeed recorded at 240fps. I suspect the phone's video player recognizes that it should play at 30fps.
