Small phones don’t need to have a worse UX, a 16:9 5" screen, considered small by modern standards, is still wide enough for a one- or two-thumb keyboard. They just need to be thicker for the same performance and battery life, which is a sacrifice Apple didn’t want to make but Unihertz did. They basically integrated the corners and bezel of a rubber case (which most people would buy anyway) and instead of wasting the rear space on another layer, they filled it with the battery. Also, comfortable bezels, large tactile buttons, inherent waterproofness (IP68 even with headphone jack!) could make the Unihertz Atom L’s UX pretty good. It is also very powerful for the price point and display resolution so I think it will not become obsolete anytime soon, assuming Android 11 will continue to be supported or you can install one of the existing custom ROMs.
