The entry background color is not working on Android 4.2.2 using GT-I9295 (Galaxy S4).
Steps to reproduce :
Pull Latest https://github.com/xamarin/xamarin-forms-samples
Open EntryDemoPage
Change Entry Background color to Xamarin.Forms.Color.White
Run on device (background color is not white)
Works correctly on 4.4.3 Nexus 5. Looks like on 4.2.2 it is setting the Border color instead of the Background color
