OnePlus 7 Pro — 515 ppi, 480 dpi (xxhdpi)
The OnePlus 7 Pro was the phone that popularised the 90 Hz 1440p panel, with 1440×3120 pixels at 6.67 inches. Its ppi is high, and it was among the first Android devices where reviewers genuinely noticed the difference in smoothness rather than sharpness.

Density on the OnePlus 7 Pro
Android uses a 3× scale here. OnePlus historically shipped with an aggressive default density to make the UI feel denser and more information-rich than stock Android, which is a software choice rather than a hardware property.
What layout it actually gets
The dp width at the stock setting is around 412, wider than a Pixel. That is partly why OnePlus screenshots show more content than a same-sized Samsung — the density, not the resolution, is doing the work.
Practical notes
If you are matching a design to OnePlus screenshots, check the reported density with 'wm density' rather than assuming the panel's ppi. The two differ on this generation more than on most phones.
