Nokia launched its Lumia series of smartphones back in November 2011, resurrecting what at the time was the almost moribund Windows Phone operating system.
Despite proving a modest success, a number of niggling problems with the Lumia's camera and battery prevented it from truly shining.
Since then, Windows Phone OS has struggled to catch on, and Nokia's sales have likewise faltered.
So Nokia really needed to knock one out of the park with its latest flagship smartphone. With the Lumia 920, it has proved up to the challenge, delivering the Windows Phone we've been waiting for.
Design and build
Visually, Nokia has played it smart with the Lumia 920 by maintaining the striking design of the Lumia 800.
The only real difference between the 920 and the 800 is that the new device is much bigger, being nearer in size to the Lumia 900 at 130x71x10.7mm, albeit with slightly more rounded sides.
The 920's increased size, when combined with its surprisingly heavy 185g weight, means that users used to smaller devices, like the 112g Apple iPhone 5, may find it a little unwieldy.
However, for those used to plus-sized Android devices like the Samsung Galaxy S3 and HTC One X will feel right at home with the 920.
As is the case with all Nokia Lumia devices, the 920 is incredibly well built. The 920's unibody polycarbonate chassis can take plenty of wear and tear: dropping it on the pavement outside V3's office caused no damage, not even a scratch.
The Lumia 920 features a 4.5in 768x1280 332ppi, Nokia PureMotion HD+ WXGA IPS LCD display, complete with Super Sensitive touch and Nokia ClearBlack technology.
We're particularly happy to see Nokia's retained the ClearBlack technology it used in its previous Lumia 800 and 900 smartphones. ClearBlack is custom technology that helps ensure the display remains rich and sharp by producing deep blacks that make primary colours pop out. This, and the Lumia 920's dazzling brightness levels, mean text and images are very sharp.
