Pixel 7a — 431 ppi, 480 dpi (xxhdpi)
Pixel 7a is a Google device whose display works out to roughly 431 dpi, which Android classifies as the xxhdpi bucket. Everything below is derived from the panel's physical resolution and diagonal size, so you can reproduce the numbers with a calculator and a spec sheet.

Density on the Pixel 7a
At 431 dpi, one dp equals 2.69 physical pixels on this panel. That scale factor is what the system uses when it picks drawables from your mipmap folders and when it converts the layout values you wrote in dp into the pixels that actually get drawn.
What layout it actually gets
Because Android divides the physical resolution by the density scale, the layout does not see the full 431 dpi pixel grid — it sees a smaller box measured in dp. That is why two phones with very different resolutions can report the same dp width and lay out identically.
Practical notes
If you are designing for this device, author in dp and let the density scale handle the rest. If you are overriding density with wm density, remember that anything far from 431 dpi will make the UI look either oversized or cramped, because you are fighting the panel's native bucket.
