The Lumia 800 was a great phone without an ecosystem. The Lumia 900 made that phone bigger, without significantly improving on the software or specifications. The Lumia 920 came with a massively improved camera, and the updated Windows Phone 8, but it was too bulky for many consumers.

With the 925, Nokia thinks it's perfected the Lumia formula: It’s essentially the same phone as the 920 in a vastly thinner and lighter aluminum shell. Nokia's also made some improvements to the Lumia 920's camera, both in hardware and software. Is this finally the Lumia that can go head-to-head with the HTC Ones, iPhone 5s, and Galaxy S4s of the world? Read on to find out.
