Software and apps
We've already reviewed Microsoft's Windows Phone 8 mobile operating system at length, and it's fair to say that we're fans.
The good news is that it's constantly improving. While stuffing our Lumia 620 full of applications, we quickly noticed a vast improvement in Microsoft's Windows Store, which is starting to showcase more big name apps. Spotify, for example, is now available on Windows Phone 8, and we quickly spotted the likes of Whatsapp, Sonic and Angry Birds. There are still a lot of uninspiring apps in the Windows Store, but it's good to see Windows Phone 8 taking a step in the right direction.
Nokia has equipped the phone with all of its usual applications, despite the handset's budget price tag. Nokia's own mapping and GPS apps come pre-loaded, and while not as slick as Google Maps, proved an excellent addition to the budget smartphone, rendering surprisingly quickly and looking great on the 3.8in screen. Nokia Music also comes preloaded, for those not so keen on Spotify or Microsoft's Xbox offering.
On the business side of things, although a brightly-coloured, budget-priced phone won't appeal to most professionals, we don't see any reason why not. For example, we found it very easy to set up our Microsoft Exchange email on the Nokia Lumia 620 - much, much easier than on the business-focused Blackberry Z10. Although it's cheaper than the Nokia Lumia 820 and 920 handsets, Microsoft Office comes preloaded on the Lumia 620, along with Onenote and the usual array of security features.
It might be cheap, but the Nokia Lumia 620 features a decent dual-core 1GHz Qualcomm Snapdragon S4 processor, and we noticed barely any issues with the handset's horsepower during our time with it. Swiping through apps and loading web pages is just as quick as on the Nokia Lumia 820 handset, although firing up applications proved noticeably slower.
Saying that, it's much nippier than the majority of its similarly-priced Android rivals, so we'd still recommend the Lumia 620 on a performance basis to those after a decent, bargain-priced smartphone.
