This is literally not a problem with smartphones, the problem is about the software you decide to run on it. A smartphone is simply a very powerful pocket computer.

I cannot confirm. The phone I’m writing these very words on is a Samsung Galaxy S10 Plus from 2019 running LineageOS 20, and the AMOLED display is absolutely gorgeous and looks as good as today’s top-tier smartphone screens. But maybe that’s because this is a Samsung flagship, and Samsung is notorious for making kind of the absolute best displays for their flagships.

“Search engine” is not equivalent to “Google”.
