Fantastic upgrade, amazing Camera

I've upgraded from the S8, so was a bit hesitant at losing the curved edge but honestly its not detracted at all. The screen quality is still fantastic, and watching films look incredibly bright and vivid. Camera is superb, and 4k video recording is great. The image stabilisation feature is a new addition but really brings your videos to life. Can see this being super helpful for those that do content creation. I'm so happy I took the plunge and bought it outright, was about time! If your thinking of buying, make use of the 14 day cooling off period and keep all boxes, packaging etc.
