I currently use a Pixel 3 XL, which I bought on Day 1 so I am thinking it is time to upgrade.
Oof, it was time to upgrade in 2021. Do you realize that unless you're running a custom ROM, your phone hasn't had a security patch since October 2021?
I'd definitely pick something up. I went from a 3xl to a 6xl sometime around when the 3xl when eol and it was a pleasant and not very noticeable transition. I haven't been tracking the 7a much as a result, so I'll defer to others there.
Haha, I know. Just was in a very difficult period a couple of years ago, where upgrading to a new phone was not even one of my top 10 priorities in my life then.
