Android 4.4 KitKat brought a major new feature that most users might not have come across yet. It came with a new runtime called ART or simply, Android Runtime. Since the early days Android has relied upon the default Dalvik runtime. Even though ART is currently in an experimental stage, the primary aim is to tweak it further to enhance app performance even more. A new image has surfaced online hinting at the possibility of Galaxy S5 ART support.
