What phones are those? I’m surprised that their resolution equals their definition in points. For example, an iPhone Xs Max has a screen definition of 1242 × 2688 pixels, but that transfers to a matrix of 414 × 896 points, and that plays well with Webflow:
If a phone OS is registering its full definition as resolution, that’s more an issue with the OS or the browser settings.
Take the Pixel3 XL, it has a screen definition of 1440 × 2960 pixels, yet you design for its screen with a base resolution of 393pt (Webflow shows 393px, could use pt units):
I’m not an android user so I don’t know what options are available to deal with screen definition/resolution/density at OS level and browser level.
