Reviews summary

7.5/10AVG.
RATING
Based on 20 reviews

What's good

  • Smooth performance during daily tasks
  • Good viewing angles and outdoor legibility
  • Sturdy and durable build quality

What's bad

  • Low screen resolution
  • Significant freeze-ups and stutter for more intensive tasks
  • No front camera

The Nokia Lumia 635 bundles entry-level hardware and 4G LTE in an affordable, brightly colored package. Users can easily change the color of their removable back panel to green, orange, yellow, white or black. Despite being priced in the budget range, experts point out that the polycarbonate shell is incredibly sturdy and doesn't creak or flex under pressure.

At 4.5 inches, the display is relatively small when compared to other phones like the OnePlus One but bigger doesn't always mean better. In fact, TechRadar states, "the Nokia Lumia 635's screen is very close to optimal in terms of balance between single-handed usability and widescreen media clarity." While the screen might be high in usability, it unfortunately falls flat in other areas. With a resolution of only 854x480, reviewers note a lack of sharpness in text and images when compared to other similarly priced budget phones. In addition, it does not offer the super sensitive touch display, which means users cannot operate the phone with gloves on. Despite some drawbacks, reviewers are quick to point out that the resolution is perfectly adequate for every day usage and the IPS and ClearBlack technology offers excellent viewing angles and outdoor legibility.

Show more

While the internal specs of the Lumia 635 cannot rival flagship phones, it does offer a modest 1.2GHz quad-core processor paired with 512MB of RAM. On paper, the specs seem fairly unimpressive but when actually tested out, reviewers were surprised with its smooth performance when scrolling through menus and opening apps. Unfortunately, they also noticed significant freeze-ups and stutters during more intensive tasks like installing multiple apps or playing graphics-heavy games. Internal storage is also very limited to only 8GB, though there is an expandable microSD slot.

On the back of the phone is a standard 5MP camera. CNET states that, "It's not a phone for the dedicated photographer, but Instagram snaps will be fine." In general, reviewers found picture quality fairly adequate and, due to lack of flash, low light pictures fairly grainy. Unlike many other recent smartphones, the Lumia 635 does not come with a front-facing camera.

Despite some issues, most reviewers would recommend the Nokia Lumia 635. Wired says, "The Nokia Lumia 635 is a solidly built workhorse of a phone…" Slashgear adds, "Nokia…has another winner on their hands on the low end."

Fast and cheap

Nokia's latest budget phone sports 4G and Windows Phone 8.1 out of the box, and benefits from all of the things we liked about the Lumia 630. However, it's not quite enough of an improvement to justify the additional premium.

Competent little Windows Phone 8.1 mobile with 4G

from TrustedReviews

The Nokia Lumia 635 is one of the cheaper 4G phones, and the cheapest 4G Windows Phone we’ve reviewed. However, as we said of the Lumia 630, it doesn’t feel anywhere near as competitive as the Lumia 520 and Lumia 620 did when they were released back in 2013.

Has Nokia been lazy? It’s not necessarily a case of laziness, but in having to make a bit more profit from each phone it sells, having now bitten off a nice bit of the budget market for itself. Keen pricing has given way to a slightly more laissez-faire approach that smacks just a little of complacency.

Overall solid Windows Phone that only makes a few sacrifices to be so affordable

from WPCentral

The Lumia 635 might be one of our favorite budget Windows Phones around. It's not as cheap as the Lumia 530 or BLU Win JR, but the display quickly makes up for the price difference. Do consider the Lumia 530 or BLU Win JR if your budget is tight, however we recommend the Lumia 630 over the two if you can afford it.

Already have a high-end Windows Phone like the HTC One M8 or Lumia 1520? The Lumia 635 makes an excellent back-up phone in case your primary device takes a nasty spill. We're also a fan of bringing the Lumia 635 to places we normally wouldn't want to bring our expensive Windows Phone. Places like the gym, or mountain biking are where you might want to grab a Lumia 635 as a secondary Windows Phone.

Is the Lumia 635 a low-price winner? Yes. You get an attractive Windows Phone with enough money left over to buy some lovely accessories, apps and games.

Mobile Syrup

Fluid software experience, compact chassis

from Mobile Syrup

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 $200 price, the company's first Windows Phone 8.1-based handset is light on the features but heavy on the charm. Decent performance and a great user experience is tempered by a poor camera, an underwhelming screen and lacklustre app selection.

GottaBeMobile

A monumentally cheap smartphone running Windows Phone 8.1

from GottaBeMobile

The only thing you can judge the Lumia 635 by is whether it reliably delivers on the things it promises and the market it’s aimed at. The Lumia 635 is a decent smartphone for users who aren’t too demanding, with the only real downsides being its rear-facing camera’s lack of flash and those apps that aren’t available on it. For a larger smartphone platform, this wouldn’t be a problem, but the Lumia 635 is a Windows Phone, which already takes its share of knocks for not having as many apps as Android or iPhone. Thankfully, many Windows Phone 8.1 apps are being updated to take advantage of less powerful devices.

The Lumia 635 is a great smartphone at a great price with two huge issues. Its camera isn’t great, but including flash would have at least helped in low-light. Not including flash hurts what’s otherwise a pretty robust package. The Lumia 635 is great for new smartphone owners and users who aren’t too demanding when it comes to games.

Clearly, though, photographers and those used to other high-end smartphone like the latest iPhones should look elsewhere. Under no circumstances is the Lumia 635 to be purchased with any kind of photography in mind. That’s a shame because design-wise the Lumia 635 is pretty solid.

Saddest thing about the Lumia 635 is the complete lack of a front-facing camera

from Digital Trends

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. If you’re looking for a budget smartphone and don’t mind learning the ins and outs of Windows Phone 8.1, the Lumia 635 might just be the phone for you.

Phone Scoop

A solid little phone, especially when you consider just how inexpensive it is

from Phone Scoop

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. The phone does a great job connecting to T-Mobile's LTE 4G network, and voice quality is really good.

Windows Phone 8.1 functioned perfectly on the 635, despite the limited RAM and middling processor. All of the main OS features, including the Cortana virtual assistant, performed exceptionally well. New features — such as Action Center, notifications, the trace keyboard, and others — make the 635 a solid contender with today's inexpensive Android phones. Perhaps the biggest failing is the camera, which only rates "adequate" in my book.

T-Mobile is offering the Lumia 635 at a rock-bottom price point. If pricing is a major concern, the Lumia 635 is the budget phone for which you are looking.

Re/code

No Selfies, but a good bargain

from Re/code

The Lumia 635 features a quad-core processor from Qualcomm. It’s a less-powerful version than the ones found in more expensive, high-end smartphones, but I found that it handled various tasks — checking email, browsing the Web, playing casual games and streaming video and music — without problem.

Call quality was also clear as I made several calls around San Francisco using T-Mobile’s network, and I experienced fairly good data speeds. Based on Ookla’s Speedtest app, I averaged download speeds of 9.47 megabits per second and upload speeds of 7.95 Mbps. When my colleague Walt Mossberg tested the 3G-only Moto E, he struggled to get download speeds of even 2 Mbps, though this was over AT&T’s network, and in different cities (New York and Washington, D.C.).

While it won’t satisfy the needs of selfie fans, or anyone looking for the greatest and latest in smartphone tech, the Lumia 635 offers first-time and budget-conscious buyers a great value.

Laptop Magazine

Offers a vivid display, snappy performance

from Laptop Magazine

No, you don't get a front camera or flash on the back, but the $168 Nokia Lumia 635 is a solid choice for the price. This Windows Phone delivers smooth performance, long battery life and a surprisingly lovely display. The 5-MP camera isn't great, but Nokia's suite of camera apps helps make the best of it.

Prefer Android to Windows Phone? Shoppers should check out the $150 Alcatel One Touch Fierce, which is slimmer and lighter than the Lumia with a brighter display. You'll also benefit from a much bigger app selection. But if you're willing to take Microsoft's user-friendly and fun interface for a spin, the Lumia 635 will satisfy.

The price is right but Windows still scares me because of the lack of apps.
