Totally out of date, but a small reminder about screen size. The key dimension is not the screen diagonal, it's the whole phone width.

In my case (and only my case), a phone wider than 65mm is difficult to manipulate with one hand only. My X Compact has almost the same screen dimension as the J1, but it's 3 mm narrower, and this changes everything...but has not SFOS...yet.

Beautiful rendering though.
