This is my Samsung Galaxy S21 Ultra at full mag. That's a shade over 1/2 inch (12mm, rounding crudely) for the image width (well, it would have been the width if the phone didn't insist this was a vertical when it wasn't).
That definitely meets W. H. Walmsley's original definition of macro from 110 years ago, which boils down to filling the page with something around one-inch (25mm).

Sorry about the rotation. The

My shiny new cell phone (Samsung A53) has a "macro" camera. It's not bad:
The macro camera at 4cm (allowable range is 3-5cm)
The normal camera as close as it would focus--actually, a tiny bit too close.
While I wouldn't count on the cell phone macro for something critical, and the distance range is restricting, the tiny handwriting is on the closely spaced wall.
The dark center is the best I could do with my ring light. 4cm is very close to the desk. The EXIF data should be OK for further details.

Well, right now "infinty objectives" are the darling of macro photography, and those will work with anything that can have its focus locked at infinity (my S21, my old S10, and an iPhone 12 I keep around as a def phone can all do that) and can zoom to 200mm equivalent (and again the S21 and iPhone 12 can do that).
I rigged an M42 adapter to center objectives over the tele camera on the S21. (M42 is my lingua franca, I have adapters from M42 to every objective size I use: RMS, M25, M26, M27). It does surprisingly well.

The term "mirrorless" is totally obsolete. It's time we call out EVIL for what it is. (Or, if you can't handle "Electronic Viewfinder Interchangeable Lens" then Frenchify it and call it "LIVE" for "Lens Interchangeable, Viewfinder Electronic" or "Viseur électronique").
