Android Question Galaxy S8+ scala

The scale is 4 (640 / 160).
Always use variants with a scale of 1 (normalized variants). Non-normalized variants will only make things more complicated.
The normalized variant in this case is:
285 * 692, scale = 1.0.

Are you sure that the values you posted are correct? Looks a bit too thin.

I think it is more like 1440 x 2792 x 3.5 (dpi is 560) which will normalize to 411 x 797 x 1.0 (dpi = 160)

Hope this helps !!
