Android 4.2, Jelly Bean improves on the
speed and simplicity of Android 4.1 and
includes all new features – Photo
Sphere and a completely redesigned
camera app, new Gesture Typing
keyboard, Google Now with all new
cards, and much more.
Everything in Jelly Bean feels fast,
fluid, and smooth. Moving between
home screens and switching between
apps is effortless, like turning the
pages of a book.
Jelly Bean improves performance
throughout the system, including
faster orientation changes, quicker
switching between recent apps, and
smoother and more consistent
rendering across the system through
vsync and triple buffering.
Jelly Bean has more reactive and
uniform touch responses, and makes
your Android device even more
responsive by boosting your device’s
CPU instantly when you touch the
screen, and turns it down when you
don’t need it to improve battery life.
