I have a Samsung S20, it’s starting to have issues, so I’m looking at something decent, need large screen 6in+, prefer powerful phone for future proofing. I don’t intend to glash it the 1st year, last phone I put a custom ROM on was my Note4. Right now I’m looking at the 1+ 12 and the pixel 8 pro, the pixel 9pro is just out of my price range. Is there anything else I should be looking at?
In the US carriers have a lot of control over the software on phones bought through them (most of them). So you’d have to get the update verified and approved by them.
