What is Android 4.4?Android 4.4 is the latest version of Google's mobile operating system. The first _phone_ it features in is the Google Nexus 5, and we've been using that mobile to find out what's new in Android 4.4, known as KitKat.

Android 4.4 – InterfaceNew features win most of the spotlight in any Android update, but one of the most important changes in Android 4.4 KitKat is its new approach to interface design.
The software doesn't look radically different, but there are some quite fundamental, important alterations. The line that used to separate the shortcut icon dock from the rest of the home screen has disappeared, and so have the apps/widgets tabs in the apps menu.
It may sound trivial, but makes Android 4.4 much simpler, visually, than Android 4.3. And this change has clearly been made following some careful thought about how people actually use the system.

The blunt truth – people don't change widgets much. You generally find a clock you like, and perhaps one or two more utility widgets if you're a bit of a techy fan, and you're done. By filing the widgets menu away, out of plain sight, Google has made the system look a lot more rudimentary, in a good way.
Adding widgets is still easy, though. Hold a finger down on an empty part of a home screen and a wallpaper/widgets menu pops up. We're not yet sure if the widgets tab will remain in the Android 4.4 tablets, though.
You'll also notice that app icons have been given a refresh. They're now a bit curvier, a little bit more cartoony.

Android 4.4 KitKat's friendlier look should make it easier for technophobes to get on with. And its pared-back style is marginally better to use all-round. However, anyone who's used Android recently will feel at home. Basic navigation hasn't changed – it has just been given a bit of an intelligent spring clean.
The notifications bar is very simple compared with that of most custom Android user interfaces, though. There are no feature toggles and no brightness slider on the top level – features we find pretty useful. Instead, getting to these things takes a couple of taps.
Android 4.4 Hangouts
Like iOS, Android is also continually merging with its desktop relatives a bit.
There's deep integration with Drive – Google's cloud storage service – and SMS text messaging has been folded into Google Hangouts, the online chat side of the Google Plus social network.
It's a pretty aggressive move that wants to nudge things like Whatsapp out of the picture, but it is terribly easy to use and dead handy if you already have a pretty Google-centric digital life (i.e. you use Gmail).
However, Google has hedged its bets on this one. In the Settings menu there's a separate entry that lets you specify the SMS app you want to use.
As standard, there's only Hangouts in this menu, but you can download others from Google Play. Handcent SMS is a popular one.
Android 4.4 - Google Keep
It's not just chat clients that Android 4.4 is trying to squish, either. The pre-installed Google Keep app also wants to take down Evernote.
It lets you make coloured virtual post-its, complete with pictures and audio clips.
It's easy to use, and also lets you create reminders for future events or tasks as well as basic notes. Keep was introduced in March 2013, but it only got more advanced features in August 2013.
For example, you can now set location-based reminders – it'll give you a buzz with the reminder once your phone's GPS realises you're in the right spot.
Android 4.4 – Google QuickofficeThe most important new-ish app that's pre-installed in Android 4.4, though, is Quickoffice. It's a Microsoft Office-style suite that wipes away the sheen of one of Windows Phone's key boasting points – its Office integration.
Quickoffice was acquired by Google in 2012, but this is the first time the app has been packed into a version of Android as standard. It's bad news for third-party Office apps like Polaris and OfficeSuite.
Just as important as offering a place for people to edit or create work documents, it also gives the browser somewhere good to open up things like PDFs. Google is rapidly stripping away the need to download third-party apps for everyday purposes. Quite how much an Android 4.4 _phone_ can do without any additional apps is pretty impressive.
But is Quickoffice any good? Embrace Google Drive, where its files are saved, and it's extremely handy for light editing and reading of your documents. You get 15GB of Cloud storage as standard too (all free), which is enough for shedloads of documents.
When decent Android Office apps are some of the most expensive on Google Play, it's great to see this functionality included for free.
Android 4.4 KitKat – Other assimilations
Android is quietly getting smarter and more invasive, and it's something that's even seen in the dialler of Android 4.4. It now offers a feature called Caller ID by Google.
This clever little extra searches the web for unknown numbers, and will display company names where applicable.
It's the sort of invisible feature that's designed to be taken for granted, but is also something that shows the kind of improvements 'next gen' mobile operating systems should be making.
It's a bit scary too – but hey, this is Google after all.
The 'all seeing eye' effect is what Android 4.4 is all about, and it reaches down into the way the system is made. The new interface isn't actually part of a separate 'home screen' app as it was in the past – it's all run by the Google Search part of Android.
Android 4.4 – Google NowGoogle Now, the closest thing Android has to a digital assistant like the iPhone's Siri, is featured much more prominently this time around. You can access it by holding down the home button rather than dragging up to the Google pop-up, or simply by swiping left-to-right on the first home screen.
As before, the main Google Now view is a series of 'cards' telling you relevant location-sensitive information such as weather, the various ways you can get home from where you are and nearby restaurants.
Google claims to have increased voice features in Android 4.4, but at present they're still much more low-key than in iOS. You can apparently awake a Nexus 5, or send it to the Google Now screen when awake, by saying 'OK Google', but this simply didn't work in our testing – it may require an update we don't have.
Advancements in the Google Now search also aren't apparent yet. Google is releasing an API that will let app content become searchable through Google Now. An obvious example is that you could be directed to a recipes app when searching for a chicken korma recipe. It sounds great, but at present searches still direct you to the web. We'll be keeping an eye on how this one develops.
Android 4.4 KitKat – PrintingAnother new feature of Android 4.4 is the Printing section in Settings. This makes it easier to print directly with Wi-Fi enabled printers.
It's nothing drastically new – printer manufacturers offer apps that do the same thing – and only dedicated HP support is offered from the off. It is likely to alert more people that wireless printing from a phone is something you can actually do, though.
Android 4.4 KitKat – Tap & PayOne of the most interesting new features in Android 4.4 KitKat is Tap & Pay, but it's pretty useless in the UK. It's a hub that collates NFC wireless payments services. However, the main one - Google Wallet - is not available in the UK yet.
Android 4.4 KitKat – PerformancePerformance was never a problem with Android 4.3 Jelly Bean. It was, and is, a super-snappy system that makes complaints about the slickness of Android outdated.
Android 4.4 KitKat carries on this performance. It's fast, with the only significant lag caused by the camera app – which is likely as much down to the Nexus 5's camera hardware as the software that makes the thing work.
Should I upgrade to Android 4.4 KitKat?If you have a phone that can be upgraded to Android 4.4 KiKat, there's no real reason not to upgrade. The new design alone makes it a far more attractive interface, and it doesn't really restrict the system.
However, if you're using a non-Google phone, its likely that many of the changes made in Android 4.4 will be hidden or altered by the custom interface laid on top.
