DPI overview missing VR and 3D info

[gitcnd]

Many phones are now being used inside virtual-reality headsets, where less than half of the screen is dedicated to each eye for a huge field of view - this makes high DPI critical.

New 3D printers now exist which you can use your phone for ( https://www.kickstarter.com/projects/olo3d/olo-the-first-ever-smartphone-3d-printer ) and higher DPi means much smoother 3D print creations.
