Positive: I observe 120 fps video framerate! 
There is confusion about the actual framerate:
By the way, in the FP3 specs it’s said that it can record video in 1080p @ 30fps, but in this video you can see that supposedly it allows to record in 1080p @ 120fps with the rear camera (minute of video: 12:24), even when the youtuber sais that it should be 60fps in the definitive version because of a bug or something like that.
Anyone knows if the final version of the FP3 will be able to record video in 1080p or 720p in higher FPS than 30? It would be really nice
general fp3 discussion: link with picture
As the Sony IMX363 chip and Snapdragon 632 SoC supporting 120 fps I was optimistic,
but got dissapointed by a bug described by this review (video)
(camera app false closes at touch focus)
However the bug is not apparent right now and I get 120 fps! 
(stopwatch and frames counted)
