I honestly love the design of the X/11, it is my favorite along with the 5/SE. Although, as the OP mentioned, there is for sure a potential to refine it. I was never bothered by the notch, but I loved the uniform bezel on every side of the phone - something you don't see even on the Galaxy S20, which is a bit funny to me, tbh.
I never liked and understood why the iPhone 4's design was so acclaimed, but anyways I also look forward to the redesign in the autumn, it will be interesting to see the modern interpretation of it.
