Nokia Lumia 520 review

The Nokia Lumia 520 stormed onto the scene in 2013 sporting a solid design and specs at an incredibly affordable price which made it an instant hit at the budget end of the mobile market.

It slotted in just below the Lumia 620, propping up Nokia's Windows Phone line up at the lowest possible price point.

It has now since been replaced by the Lumia 530 and Lumia 535, and fewer outlets now stock the device, but you can still pick one up and for as little as £60 on PAYG or from £100 SIM-free.

Rhere's a whole host of competitors, chief of which is the superb Motorola Moto G (recently upgraded to the 2014 edition) – a smartphone that pretty much redefined what a 'budget' handset could be.

There are other options to, of course, such as the ZTE Blade Q Mini or the HTC Desire 510.

But here's something that may have a bearing on whether you buy the Lumia 520 – the phone is the world's top-selling Windows Phone 8 handset, thanks to its impressive specs and low-end price.

What's more, it was the third best-selling phone in the UK in December 2013 according to Jim Belfiore, the VP of operating systems at Microsoft.

This little handset has also just been on the receiving end of Nokia's Lumia Black system update that adds some extra functionality to the device as well as some new features to play with. More on that later.

The Nokia Lumia 520 has a fairly generous 4-inch, 480 x 800 display and is powered by a 1GHz dual-core Snapdragon S4 processor and 512MB of RAM.

Samsung Galaxy S7 Edge review

The Samsung Galaxy S7 Edge is a phone I'd hate to have had to make. Its predecessor was a multi-award-winning phone, simply because it packed all the power of the 'normal' Galaxy S6 and yet... that curved edge. I wasn't alone in loving it, whipping it out proudly whenever possible.

But that was last year, and the world is bored of the curved design. We've seen it. It's been done. So what can Samsung do to make the new phone a real step forward?

Well, unlike what it's done on the Galaxy S7, which looks (initially) like last year's model, the changes on the S7 Edge are brilliant, adding a zest to a design that could have quickly become tired.

The screen is larger, yet somehow the phone doesn't feel too much bigger in the hand. The rear of the phone is now curved too, making it sit nicely in the hand. It's waterproof. There's a microSD card slot. There's so much power in there I'm pretty sure I could strap it on the back of a speedboat and make my way across the Atlantic.

Samsung Galaxy S7 review

The Samsung Galaxy S7 finds itself in a slightly tricky situation. Samsung needed a big win from the Galaxy S6 in 2015, which it got after reinventing the design of its flagship smartphone, but you're not going to get the same degree of evolution again just a year later.

This means the Galaxy S7 falls firmly into the iterative camp, building on the solid foundations laid by its predecessor without fiddling with the winning formula too much.

Some will argue this phone should be called the Galaxy S6S, but are they right? I've put the Samsung Galaxy S7 through its paces to see if it's a worthy seventh-generation flagship, or a just cheeky six-point-five instalment.

There's initial good news in the fact that the S7 isn't competing as closely with the Galaxy S7 Edge as the S6 was with the S6 Edge last year, with the curved display variant getting a bump in screen size this time round, taking it more into phablet territory.
