To me I'd still say the ZenFone isn't a small phone. Not only is it bigger than my current phone (pixel 3) its also bigger than some phones in the 2010s that were lauded for their large screens. We literally have no mainstream small phones, what we call small now are just smaller than the ginormous ones that have been normalised.

Samsung basically has a duplicate app installed for each stock Google app. And I think short of disabling it via adb, there is no option. But Samsung has really turned around and has a relatively good update policy in place. If not the Pixel, then Samsung is okay for me. I had love to have the Fairphone but it seems like they sell in limited markets only worldwide.

Yeah, I'm writing this on an s10e but the battery really isn't that good anymore and the lack of security updates doesn't feel good either. The current s series phones are roughly the same size as the e though, so I hope it'll be okay.

That said, even the e is a bit too large for my taste. The top left corner is pretty much out of reach without adjusting your grip, so about half an inch less of screen would be preferable imho. Samsung's one handed mode is much better than the android default though, which kind of makes up for it - and there's just nothing smaller available.
