The Nokia Lumia 635 is a budget/mid-range Windows Phone 8.1 smartphone with a large screen, a fast quadcore processor and 4G compatibility.

Nokia - or Microsoft, as the future would have it - has another winner on their hands on the low end. If the same distribution is used as the Nokia Lumia 520 and Nokia Lumia 521, I see no reason why the Nokia Lumia 635 shouldn't have similar success.

This 4G version of the Lumia 635 is a good value Windows phone, but a brighter screen means less battery life than its 3G counterpart

Nokia as a device brand may be on its way out, but its legacy is intact with the Lumia 635. Cutting only the most necessary of corners to achieve that vaulted price, the company's first Windows Phone 8.1-based handset is light on the features but heavy on the charm.

The Nokia Lumia 635 may not have all the latest hardware or the most attractive design, but it certainly works well. It's proof that smartphones don't have to be all-powerful to get the job done.

The Nokia Lumia 635 is a competent little Windows Phone 8.1 mobile with 4G. However, a few too many little niggles and cuts mean it's not the bargain the Lumia 520 and Lumia 620 were last year.

The Nokia Lumia 635 offers a vivid display, responsive performance and long battery life at a wallet-pleasing price.

Phone Scoop | Eric M. Zeman

The Lumia 635 is a good little phone. The hardware is decent, if somewhat boring. It feels solid and the exchangeable covers are a nice option to have. The screen isn't the best ever, but battery life is quite good.

Whether you're a Windows Phone fan or someone who wants to discover Microsoft's mobile OS without breaking the bank, the 4G-compatible Lumia 635 is an excellent choice. It's responsive and comes with Windows Phone 8.1, as well as all of Nokia's exclusive apps.

The two biggest shortcomings that you should be aware when thinking of buying this device is that the display is sub-par. It gets the job done, but pixels are grainy and the colors are quite muted. Also, the camera on the back of the device is mostly a novelty, and the lack of a dedicated camera button is discouraging.
