Hi! I found this cool and complete video review of the Fairphone 3. I recommend you to watch it because it is very detailed and with many tests 
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
