Covers almost whole screen. Which is unnecessary.
Issue:
And installer covers The application you were using.
Only way to get back to app you were using is, to Open recent apps, Swipe and then get back to app you were using.
You have to manually open recent apps and then only you get back to app you were using. ANNOYING.
SUGGESTION:
Hitting back while installing app doesn't do anything. It should minimise the installer or run it in the background, and give a notification when installation completes.
