I have an S10e. Coming from the 2016 iPhone SE I was looking for something a bit larger, but still reasonably small. It was a bit bigger than I would have liked, but I thought it would be fine. It's not. It's too big for me and I'm an adult male with relatively large hands. I'd be all over the 12 mini if it weren't for the price.
So s10e is still the biggest one of "high-end small phones" though it has the best screen ratio by far.
I do think mini might be just the right size! I hope this will prompt more small phones on the market!
