The Lumia 520 is the most affordable Windows Phone ever made by Nokia. However, in a bid to keep the device's cost down Nokia has stripped the device of close to all the innovations that made its Lumia devices great, diminishing the 520's overall appeal.

The Nokia Lumia 520 was unveiled alongside its more expensive sibling, the Lumia 720, at Mobile World Congress in February.
The 520 is the fifth Lumia smartphone to arrive on British shores and is designed to complete the company's current generation portfolio of devices, replacing the 620 as Nokia's cheapest Windows Phone 8 handset.
Despite costing a modest £150, the 520 still retains all the inherent business benefits of a Windows Phone handset. Nokia claims that this makes the Lumia 520 the ideal choice for small to medium-sized businesses looking for affordable work phones.
Design and build
The Nokia Lumia 520 looks very different to any of the Finnish firm's previous Lumia handsets.
Visually the device looks like a cross between Nokia's mid and low-end Lumia 620 and 820 handsets. The 520 features slightly harder corners than the 620 while still being curvier than the 820.
The budget Lumia also sits between the two phones size and weight-wise, measuring in at at 199x64x9.9mm and weighing 124g.
The tiny 620 measures in at a slightly condensed 115x61x11mm and weighs a comparable 127g, while the 820 measures in at 130x71x10.7mm and weighs a staggering 160g.
In hand, this means that the 520 is fairly comfortable with the three buttons on its right-hand side, for power, camera and volume, remaining reachable for most.
In general, the 520 also keeps ups Nokia's stellar track record for building robust, sturdy, drop-resistant handsets. During our tests we found the 520's plastic outer chassis, while proving a little bendier than we'd like, was able to deal with more than the usual wear and tear, surviving an accidental meeting with the patio floor of a friend's flat with only a few scuff marks.
Our only qualms with the 520's design is that its detachable case and plastic screen cover are both prone to picking up dirt and scratch marks.
Luckily, the 520 features interchangeable covers, meaning you can replace the chassis if it gets too dirty or change to a less dirt-attracting colour option.
The screen however can't be changed and is a bit of an issue, with it permanently looking slightly greasy, even when given a decent polish.
