I also want to comment on the camera of the S20 Ultra. Don't get me wrong, it's an amazing piece of kit that is above anything offered today. But even then, the zoom capabilities are still mostly digital. The actual optical zoom is 4x. Which is still a lot better than anything out there today. And I've tested it in store myself. 10x is near lossless, 20-30x is still good. Above that it starts to degrade.
It's just that Huawei is about to release their flagship series P40 with even the lower grade phone offering 5x optical zoom and the premium a whopping 10x pure optical zoom. That still trounces the S20 Ultra-by quite a bit. I'm really hoping Sammy matches that next year with the S21. If it does, I'm definately buying.
I don't mean to knock the S20 Ultra as it's amazing what it can do and far above anything out there today. But really, most of the zoom levels even at medium zoom levels are the results of brilliant digital programming.
Whilst 4x optical zoom is significantly better than anything else, it's not next level. I would call 10x optical zoom a truly next level zoom in a smartphone.
