Hey :
Thanks a lot. I have attached the Android screenshot and the iOS screenshot:
Android Note 4
iPhone 6s
It is mostly the background image that you can see is much crisper in the android, which is very evident in VR because the blurriness hurts the depth feeling.
As for the settings, I started with the Tappy Chicken DefaultDeviceProfiles.ini. Then the only things I edit were the two you mentioned to the values we mentioned. (MSAA-4 and Content Scale-3)
I hope this is enough info. I can provide any other info as well, just let me know.
Thanks,
