Yes, but no "flagship" devices from mainstream brands, only specialty/novelty stuff. The last <6" flagship I'm aware of was the Asus Zenphone 10 in 2023.

Yes and now.

Technically yes: there is iPhone 13 Mini and in Android world there is 2 or 3 Unihertz models and some "no-name" Chinese Aliexpress brands (Cubot has some small model, AFAIR, and there is several even more no-name offers).

Realistically no. All these Android models are underspecced. Old cores (8+ years old), small screen resolutions (small in PPI, not like small as screen proportion to big ones), small amount of RAM and storage (latest Uniherz is happy exception in this area, but not in the others), very bad cameras, very short OS update period (if ever).

iPhone 13 mini is Ok-ish (my wife uses one): camera is still very poor, but all other is usable.

Android is worse. If all you need are phone calls, and messaging with Telegram/Whatsapp/Signal it is Ok. But if you need good camera, good browsing experience (many open tabs) or something specific you are out of luck. Even Google Maps could be sluggish. Plus zero-days in old Android versions.

Good cameras is my pet peeve: good ones go only to flagship models and maybe sub-flagship ones (like, flagship and sub-flagship can be differentiated by addition of tele-module, which is most useful for me).

yes. I use this one https://www.unihertz.com/products/jelly-star
