Generic 720p Android phone — 270 ppi, 320 dpi (xhdpi)
A generic 720p Android phone represents the budget and Android Go tier. The low physical resolution paired with a large diagonal produces the lowest ppi you will find on a currently supported Android device.

Density on the Generic 720p Android phone
At this ppi the density lands in hdpi or xhdpi depending on the exact panel size, giving a 1.5× or 2× scale. That is the reason budget phones need their own drawable exports: xxhdpi assets would be wasteful, and mdpi assets would look blurry.
What layout it actually gets
The logical width still comes out near 360 dp, because Android compensates for the low resolution by lowering the density. This is the single best illustration of why dp is a physical-size abstraction, not a pixel count.
Practical notes
Treat 720p as your low-end performance target. If your layout depends on large background images or many layered shadows, this is the device class where it will visibly stutter.
