Behind the polish on the screen is the power under the hood. Take the Phone app, which for most people hasn't really changed since the days of flip phones. Now, we're making calling easier than ever, by helping you search across your contacts, nearby places, or even Google Apps accounts (like your company's directory), directly from within the app. And with the new Hangouts app, all of your SMS and MMS messages are together in the same place, alongside your other conversations and video calls, so you'll never miss a message no matter how your friends send it. This is just a small taste of KitKat-learn more on our site.
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 Android's 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.
Along with our sweet naming tradition, we also introduce a new device with each platform release to showcase the latest Android innovations. For KitKat, we partnered with LG to develop Nexus 5 -- the slimmest and fastest Nexus phone ever made. Its design is simple and refined to showcase the 5" Full HD display. Nexus 5 also keeps you connected at blazing speeds with 4G/LTE and ultra fast wifi. The advanced new lens on Nexus 5 captures more light for brighter night and sharper action shots. And with optical image stabilization, you no longer have to worry about shaky hands and blurry pictures. A new HDR+ mode automatically snaps a rapid burst of photos and combines them to give you the best possible single shot. Learn more on our site.
