I understand that Apple did not make enough money to make it worth their while to continue the iphone mini line. However, it does seem like there is a profitable business for someone there given how beloved it was/is.
I only traded out my iphone 12 mini just recently for an iphone 16 pro (likely the last apple product I will ever buy but thats another story) and aside from the camera it is basically the same. Just heavier, awkward to hold and slightly worse designed.
No major player wants a smaller screen because it has downstream impacts on the pipeline of addictive material and ad pixels they can stuff into ocular nerves.
The first phablets were probably the Galaxy Note line starting in 2011 which was met with some skepticism due to the size of them. These were well before the edge to edge screen days. So you had 5.7 inch screens with a bezel.
They were huge but I would routinely see small women pull these things out of their hand bags and press a device that obscured almost their whole face and start chatting.
Things steadily got bigger from there. The general population WANTED this.
It's a vicious cycle. Phone manufactures make the screen bigger, app and website developers realize they can cram more junk on the page, consumers demand larger screens as a result, return to step 1.
