To me, it's always a lack of choice first, budget constraints second. I personally despise a lot of design choices of smartphones, such as touchscreens (they're battery drainers), lack of physical keyboard and a "make it as flimsy as possible" mentality

A Moto Droid 3 with more up-to-date insides (a midrange spec from 2018 is more than enough) would be an instant buy for me.

I currently have a Galaxy S8, I find it stupidly and needlessly big, but I got it used for cheap and I use the camera a lot, which was the main reason I bought it. Before that, I was using a Xiaomi 6X (MiA2), which was pretty much the same size as the S8, until the USB port got fucked up
