The Nokia Lumia 630 is the first Windows Phone to arrive straight out of the box with Windows Phone 8.1.Price-wise the Lumia 630 slots into the bottom end of the range just above the Lumia 520, but it comes jam-packed with features thanks to the upgraded operating system, therefore you get a lot more bang for your buck. Windows Phone 8.1 offers a lot more upgrades and additions than you would expect from the usual’point upgrade’, it’s almost a complete overhaul of its predecessor.
All of the desirable features of Windows Phone 8 remain, however the upgrade pushes the OS closer to its competitors iOS and Android, replicating their existing features with the likes of the new Word Flow Keyboard and Action Centre.
