Android chief Sundar Pichai said "The first thing you’ll notice about KitKat is we’ve made the experience much more engaging: the book you're reading, the game you're playing, or the movie you're watching—now all of these take center stage with the new immersive mode, which automatically hides everything except what you really want to see."
He added that the phone itself is "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."
Carphone Warehouse will sell the device for £295 . Official Google Play Store prices are £299 for the 16GB model and £339 for the 32GB model.

The new operating system also updates Google's Hangouts software and the phone's dialler, which will now identify incoming calls from contacts stored across a user's various profiles and accounts. The device will also feature the ‘hot word search’, which means it is always ‘listening’ for the phrase “OK Google”, which can then trigger voice commands.
Featuring a Snapdragon processor, the device also emphasises Google Now, which can, for instance, integrate notes left by users with their location. This allows it to show a pre-set reminder to buy milk when a user is near a supermarket.
The screen offers 445 ppi, while the device measures 69.17x137.84x8.59 mm and weighs 130g. As with previous Nexus models it also features wireless charging and NFC.
Pichai added that "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."
