Building a platform that makes mobile phones accessible for everyone has always been at the heart of Android. Until now, some lower-end Android phones couldn't benefit from more recent Android releases due to memory constraints. With KitKat, we've slimmed down Androids memory footprint by doing things like removing unnecessary background services and reducing the memory consumption of features that you use all the time. We did this not only within Android but across Google services like Chrome and YouTube. RAM (or memory) is one of the most expensive parts of a phone, and now Android can run comfortably on the 512MB of RAM devices that are popular in much of the world, bringing the latest goodies in Android 4.4 within reach for the next billion smartphone users.
