I hear you. My last phone was an ancient Xperia from about eight years ago–but I finally needed to get a new one. I love most everything Sony is doing with the Xperia series, and I would have gotten another. But the update guarantee was so abysmal I just couldn’t do it. So now I have a Pixel which I think is worst in design in a lot of ways. But at least it will be updated. (And can run GrapheneOS).
