Phone vendors are being a bit anti-consumer
I'm not especially bothered about aspect ration as long as I can hold the damned thing.
By Nokia 808 was a technological marvel. Small but weighty and seemingly indestructible.. ok after many years the xenon flash stopped working (remember those?) , easy to hold, industry beating camera and sound recording (never really surpassed though cameras now have some useful tricks and are much faster), oled screen replaceable battery, absolute works but Symbian effectively died.
I then switched to an LG G4, which was a total fail, the thing was huge and by modern standards it's not even considered that large. Not to mention bootloop and battery issues.
Phones that I can fit in my hand are rare, I ended up with an iphone se which is a near ideal form factor, I could take some a little larger - say a 6s, but i think even just reducing bezels would be sufficient.
I would quite gladly have continued along apple road but getting rid of a headphone jack is just stupid and benefits no one. Then, android manufacturers in their stupidity join that party as a feature so that they can make the phones even thinner and more fragile.
Google were joking about it one year and then removed it from the pixel 2? At least that isn't giant and would be appealing but they decided to get rid of the main thing pushing me from upgrading to a new iphone.
There are clearly gaps in the market but the designers seem keen on not filling them.
