Description

Hi @NathanWalker,

Issue Description

I have sizing difference between IOS simulator and Android Emulator! after a build to device it appear that the sizing match on real device but not on simulators.

Android has some 5 DPIs more than android ! it is confusing because when loggin the width and the height is log same think but visually isn't the same!

is that the expected behaviour ?
