The group that was once Nokias mobile division has gone through a great number of changes in the past few years. After declining sales of Symbian devices, the company decided to go all in with Microsofts Windows Phone platform. In a very short time, Nokia became the number one vendor of Windows Phone smartphones in the world. Despite this, the move to Windows Phone failed to revitalize the company. In August of last year, Microsoft purchased Nokias mobile devices business in a 7.2 billion dollar acquisition. Less than a month later, Microsoft launched the Nokia Lumia 830, and the Nokia Lumia 735. These were the last two Lumia smartphones that would be branded as Nokia devices. With Nokias phone division absorbed into Microsoft, future Lumia devices would fall under the Microsoft brand.

Todays review focuses on the Microsoft Lumia 640. This phone was announced alongside the Lumia 640 XL at MWC in February, and its one of the first new Lumia devices released under the Microsoft brand. At $129, the Lumia 640 occupies a fairly low price point as far as smartphones are concerned, and it serves as an entry model to the Lumia smartphone line. To see how it compares to the competition, and to its fellow Lumia devices, read on for the full review.
