good idea! great job with the execution. Eventhough it is not great but at least can see the great amount of afford being put into creating the video.

A few things you need to improve:
- what is camera 1, camera 2 and camera 3? Why can't you put iphone 7, samsung and so on?
- your video should be shot at the same time using all the cameras. Look at some of the youtubers out there. They tie the phones/cameras together and take the shots at one go. more side by side comparison instead of playing the videos one by one.
- compare OIS also.
- compare in daylight, night, ourdoor, indoor and so on
