Sharp has announced its intention to manufacture the world's sharpest display, a 5.5" IGZO screen with a 4K/UHD 3840x2160 resolution (806 pixels per inch), for some 2016 smartphones. Is 806 PPI too much? Tom's Hardware notes the drawbacks while celebrating the new milestone:
Although devices that are 1440p or even 4K will look even more stunning, there are indeed diminishing returns benefits-wise as the cost, the power consumption, or the GPU resources required to handle such high resolutions are significantly higher than the previous generations.
That's not to say that a 4K display today will necessarily cost more than a 1440p display did last year, but it does cost significantly more than a 1440p display being sold this year. Although the price ratios for components may remain relatively the same for the new technologies inside a new smartphone, if the benefits are increasingly smaller, then there's an opportunity cost, as well.
For instance, the extra cost to get a 4K display over a 1440p display this year could be used instead towards improving the device's camera. (OEMs could use a sharper lens, a larger sensor, improved OIS, and so on.) This sort of balance should always be taken into consideration.
[...] That doesn't mean higher resolution displays in smartphones are not useful. However, they could be even more useful for other applications; for example, 4K displays are ideal for VR. In order to have a VR experience that makes you completely forget you have a screen in front of your eyes, you'll need at least a 4K resolution screen.
Higher-resolution displays will also help lower the cost of lower resolution panels.

Sony Xperia Z3 compact. All the power of the flagship Z3 and a 4.6" screen.
I hate the ethics of the company but they make some damn good phone hardware. They are the only ones who don't neuter their smaller phones. The compact has the same chip as the fullsize.
I am still very happy with my original Xperia Z and if it ever dies then the Z3 compact is my number one choice. I was very envious of a friend that had the Z2 compact (which he dropped over the side of his boat).

No need to be envious. It isn't exactly the same, but you could just throw yours in the toilet.

Got a Sony Xperia Z3 Compact in my house. Stonkingly good phone. Ignoring it's Sony, and using as a Stock Android phone (Sony put hardly any crap into the OS) and you get a REALLY good phone that's well built and powerful.
This is my opinion, there are many others, but this one is mine.

Too bad Sony doesn't make any phones with OLED display (that's what gsmarena.com/search.php3 told me)
