Screen size stops being meaningful when you start comparing phones released years apart - the 5" Shift5me is 141,5 mm x 71 mm, phones around that width have seen screens all the way from the 4.3" of the 2011 Philips W920 to the 6.2" of the 2024 Samsung S24. For reference, the S4 mini was 4.3" at 124.6mm x 61.3mm.

But if that is an acceptable size of a phone, there are still few of those around, thankfully. It's just about the limit of what I can comfortably handle at all (Pixel 4a currently)

It's great, but a bit too small and thick (...let me just stop you there), and the design is just not really modern or elegant. I didn't have problems typing on it, personally. But it's either the Jelly Star, at 3", or you basically jump straight up to 6" minimum.

Interesting, but taking it a too far to the tiny end - I don't need a phone I can hide in my prison pocket, just one that fits in my regular ones.
Also Unihertz has terrible software support and doesn't provide android upgrades for their phones, so it's already in a sense 7 months out of date - and sadly obscure enough that there isn't much custom rom development either.
