https://material.io/resources/devices/ (which is not maintained anymore) has
3.5x for xxxhdpi google pixel xl
4x for xxxhdpi galaxy s8
https://material.io/blog/device-metrics lists only 4x for xxxhdpi
https://reactnative.dev/docs/pixelratio lists only 3.5x for xxxhdpi
So it's very confusing, galaxy s10 has 550ppi and falls into xxxhdpi
Is it 3.5x scaled or 4x scaled?
Is it different depending on whether we are on native android or react-native android?
