Product Nokia Lumia 630
Specifications 4.5in 854x480 Clearblack touchscreen display, quad-core 1.2GHz Qualcomm Snapdragon 400 processor, 512MB RAM, 8GB internal storage with microSD card expansion up to 128GB, 5MP rear-facing camera, 3G and 802.11a/b/g/n WiFi connectivity, 1,830mAh battery, Windows Phone 8.1 mobile operating system, 130x68x9.2mm, 134g
THE NOKIA LUMIA 630 is the first smartphone to arrive running Microsoft's latest Windows Phone 8.1 mobile operating system, which brings features such as customisable backgrounds, Action Center and enhanced enterprise support.
This, combined with the Nokia Lumia 630's £100 price, means that on paper the handset could be one of the best choices for companies looking for an affordable smartphone for a mass rollout, and could lure consumers away from handsets like Motorola's £89 Moto E smartphone.
Design and build
The Nokia Lumia 630 features a design that's similar, albeit slightly boxier, to that of its predecessor, the Lumia 620. The brightly coloured handset features a polycarbonate, hard edge removable chassis, with rounded corners and flat back and side faces.
The polycarbonate used in the Nokia Lumia 630's interchangeable covers doesn't feel nearly as top-end or robust as that seen in higher end Lumia phones, such as the upcoming Nokia Lumia 930, but we are fans of the design.
As well as granting access to the phone's removable battery, micro-SIM and microSD card slots, the fact that the covers are interchangeable means that you can customise the phone's appearance and replace the chassis if it is damaged.
We also found that, despite the Lumia 630's hard edges, the phone was fairly comfortable to hold. This is largely down to the 130x67x9.2mm measurements and reasonable 134g weight. The measurements mean that the Lumia 630 hits the same size sweet spot as devices like the Moto G, and is large enough to function as a smartphone without being too big for small-handed users.
Screen technology has generally been an area in which budget smartphones have compromised, with most sub-£100 handsets featuring blurry, pixelated displays that severely hamper the user experience.
The Nokia Lumia 630 display is far from perfect, even when compared with its key competitor the Moto G, which features a 4.5in 1280x720, 329ppi display, but it is still significantly better than all other similarly priced handsets we've experienced.
The Nokia Lumia 630's 4.5in 854x480 218ppi IPS LCD capacitive touchscreen, while a little hazier-looking than we'd like, in general is very good considering the phone's price. Colours and icons are vibrant and text displayed on the screen was always readable.
This is in part because the Lumia 630 features Nokia's custom ClearBlack display technology. ClearBlack helps ensure that the display remains rich and sharp by producing deep blacks that make primary colours and text pop out.
