Hi have a project and create one app for iOS and one for android, both based on the same layout and cards, but the result are different for each platform.
I just rebuild the apps with the latest version 2015.3
this is the way it looks in iOS
and this is the way it looks in android
this are the setting for the top card on the layout
I agree with you, android seams to respect the percentage that I'v set on the manager, but also the manager show a preview more similar to the iOS render, so probably there are some bug there too.
