After upgrading, you'll see the following improvements to the Android operating system and other apps.
You can now stack widgets, combining multiple widgets into a single block on your home screen.
Instead of taking up several grids on your home screen for your weather, calendar, battery, and music player, stack them and swipe the stack to switch between them.
You can now use an icon theme that coordinates with your overall theme. Touch & hold a blank space on your home screen, then tap Home settings > Themed icons.

You can now limit this brightness to a more comfortable level by adjusting the intensity of Enhanced HDR brightness or turning it off to force HDR photos and videos to play at a normal brightness level.
