I'm honestly content with my Note 10+. It would be neat if Samsung listened to critics on YouTube, they all say pretty much the same stuff; enable high refresh rate at max res, utilize the same chip for the same model wherever it's sold, and add a headphone jack. It shouldn't be so difficult to make a near perfect phone. Give consumers an Exynos + Radeon chip, an under screen camera, move the curves of the screen from the sides to the top and bottom, and perhaps minimize the camera bump that literally no one asked for, add a headphone jack (maybe if it's repeated enough it will happen), and you have a pretty neat phone. If the screen is curved vertically, than the speakers could be moved to the side of the phone, 2 per side. That would enable pretty excellent audio. As for the camera bump, perhaps a single Ultrwide with a 108mp sensor? It may shoot at a high enough res to enable decent digital zoom, kinda like the Nokia Lumia of old. And why not have the S Pen slide in the side of the phone? Seems like it would save space, and the size could be maintained via a telescoping body (see 1st gen 3DS). I'd upgrade for that.
By moving the curves, you reduce the chances of accidental touch, you can fit a wider aspect ratio on a device of the same size as it is currently, (21x9 perhaps) and the sides of the phone can be flat allowing for a better gripping surface. You could also use 4 loud speakers, each located near a corner of the device, to create a really great audio experience.
I care less what is under my Note 20 Ultra's hood, I do not care what chip or cooling system, just so as long as my Note 20 Ultra works just as it should, my 20 is working just fine and if it gets itself into a pickle, I will call Samsung to get the phone fixed or replaced very simple very easy.
I'm loving mine too! I just wish they included the wired headphones. Even with buds there's still scenarios where the wired are needed. for example if I'm working in 2 ft. of water. God forbid one falls. it's ruined.
