I'm not talking about rooting, but rather little things like changing
notifications sounds and customizing the look of the homescreen
via widgets.
There is now support for multiple user accounts on tablets, native settings shortcuts in the
notifications pane, gesture typing (ala Swype), wireless screen streaming
via Wi - Fi Direct (over the Miracast protocol),
widgets on the lockscreen, support for USB audio docks, redesigned camera app with HDR mode, Photo Sphere capturing and a built - in editor with filters, as well as further stability improvement.
Android 4.2 featured new lock screen
widgets, more improvements to the stock Android camera app, gesture - based typing and new quick settings shortcuts accessible
via the
notification bar.
