I always said a 2016 era slim 5.2" phones was as big as I would tolerate, for exactly that reason: one handed use.

However, while i still have the same requiirement, the march of progress in thinning bezels and slimming screens means that I'm quite comfortable using my wife's Xiaomi MiA2 with its 6" 19:9 screen.

Looking forward to the XA2 Plus turning up in the UK at a REASONABLE price.
