Google's version requires one more tap to toggle the secondary panel for the common settings, including screen brightness, WiFi, auto screen rotation toggle and airplane mode.
Initially split up into four distinct screens, a toggle allows users to swap between dual-screen mode for convenient multi-tasking and a single screen for uninterrupted viewing of applications and content.
When the camera's completely switched off, hit the power button and you'll go straight into camera mode which lets you shoot immediately, then about half a minute later the interface seamlessly goes back to smart mode, which is when you can hit the back or home button to toggle the Android unlock screen (though we'd rather go straight into the home screen).
