As many of you already know, Android 4.1 Jelly on the Google / ASUS Nexus 7 uses a mix of tablet and phone user interfaces. The home screen launcher is fixed in portrait mode with virtual buttons at the bottom like the Galaxy Nexus, but when you go into landscape mode for landscape-oriented apps / games like Dead Trigger, the virtual buttons are placed at the bottom unlike the Galaxy Nexus. This is a completely new mix for UI (with respect to placement of virtual buttons) that has never been seen before on Android tablets; Google developed this specifically for the 7” tablet form factor.
