Nokia Lumia 635: Screen, Software and Performance

Andrew Williams

By Andrew Williams



Our Score:


Nokia Lumia 635 - Screen

As 4G phones get cheaper, though, you can no longer assume that a 4G mobile will be as capable in other areas. The Nokia Lumia 635 screen is a case in point – it’s fairly basic.

You get a 4.5-inch 854 x 480 IPS LCD screen, one that has an extra 54 pixels in height to give that bit of extra room for the software nav keys. Despite those extra pixels, this is a pretty low-res screen.

The limits of the 218ppi pixel density will be immediately obvious if you’ve used a sharper phone before. 18 months ago this sort of resolution used to be the norm in sub-£150 phones, but no longer. Phones like the Motorola Moto E, Moto G and EE Kestrel have taught us to expect a bit more.

And to our eyes 854 x 480 resolution in a 4.5-inch screen just doesn’t quite cut it anymore.

There are also some other issues. The blacks have a blue tint to them, reducing how punchy and vivid the screen looks, and there’s pretty significant loss of brightness when you view the screen from a horizontal angle. As this is an IPS display, though, viewing angles are otherwise good.

On the more practical side, the Lumia 635 doesn’t have an automatic brightness setting, something that requires an extra bit of hardware on the front of the phone: an ambient light sensor. This means you have to manually bump-up the brightness setting when you go outdoors.

There are only three backlight settings – low, medium and high – so flicking between them isn’t too arduous. But it does get annoying.

Given this limited control, it’s a surprise that the Lumia 635 gives you such good control over the character of the display. In the Settings menu you can alter the colour temperature, colour saturation and green/purple tint. With a bit of a fiddle you should be able to get fairly decent colour reproduction.

If you find the three Lumia 635 brightness settings don’t suit your needs, you can also alter exactly how bright each of these is. It’s patching up a hardware deficit with software, but it is better than nothing.

There’s nothing that can really fix the resolution issue, though. While the pixel structure isn’t as apparent as it is in some lower-quality LCD screens, we find it limits the enjoyment of playing games and browsing. The sharpness you get in some Androids at the price just isn’t here.

Nokia Lumia 635 - Software

The Nokia Lumia 635 runs Windows Phone 8.1, an updated version of Windows Phone 8 that adds a few important features and takes away a few restrictions.

It is what makes the Lumber 635 hardware possible, allowing things like software nav keys and letting manufacturers leave out a camera button. It also adds a few features that make Windows Phone feel a bit more like Android.

Action Center is Windows’s equivalent of the drop-down notifications menu. It shows you your latest updates, and gives you four little buttons to toggle features and head to the camera. As standard, you get Bluetooth and Wi-Fi switches and a screen brightness toggle, plus that camera shortcut.

We used to praise Nokia’s budget Windows Phone as some of the best ways to get super-cheap phones that are still slick, but now that has changed a bit. Phones like the Motorola Moto E and Moto G offer good performance on a budget, and there are some ways they can feel faster than the Lumia 635.

Nokia Lumia 635 - Performance

Cheaper Windows Phones like the Lumia 635 are good as making swishing through the basic interface quick. One of the key early aims of the system was to offer better all-round performance across the lower price bands than the competition.

However, you do see where the Lumia 635 is a bit less capable in its app load speeds and in-app performance. The phone has just 512MB of RAM, which won’t help in this field. Some apps take a couple of seconds to load where they’ll fire-up more snappily in something like the Lumia 930. The processor is pretty good, though.

Nokia uses a Snapdragon 400 quad-core 1.2GHz CPU in the Lumia 635. That’s the same CPU as the Motorola Moto G, and even much more expensive phones like the Sony Xperia T3. It’s a pretty good chipset.

Our usual benchmarks like Geekbench 3 aren’t available for Windows Phone, so we tried the Sunspider Javascript benchmark instead. Using the inbuilt Internet Explorer browser, the Lumia 635 took 1460ms to complete the test. For a couple of comparisons, the Moto G (using the Chrome browser) took 1290ms and the Lumia 930 a blistering 512ms. It's an entry-level performance.

Nokia Lumia 635 - Apps and Games

Still, performance is no grand issue with the Nokia Lumia 635. What we found more annoying was the standard old complaint of Windows Phone that hasn’t changed – the apps and games situation.

The Windows Phone app store now has more than 300,000 apps, but you wouldn’t know it from browsing its shelves.

We won’t be too cruel – the vast majority of the ‘standard’ smartphone apps are here. Social networking, music streamers, and all kinds of utilities are covered. However, there’s not the same sort of app culture as there is on iOS and – to a lesser extent – Android.

If you want to discover a cool new app and game every few days, you’d be better off with an Android phone. If you’re not much of a gamer and don’t need more than the app basics to cover each are of your digital life, there’s nothing to worry about. This is one of the reasons why Windows Phone has suited lower-end devices so well over the last couple of years.

That is provided that EE and the rest get rid of the ridiculously excess surcharges for such a service, which they most likely, unfortunately, won't

worst phone Ive ever owned, so many software problems; volume down button wont work; it instantly goes back up to full volume. restarting the phone only fixes it for maybe 10 minutes. very annoying if you're in public- I had to turn the phone off because It wouldn't stay on vibrate.
touch screen only works when it wants too(you have to lock and unlock the screen way to often for it to acknowledge you're swiping )
touch screen constantly freezes.
if you plan on listening music, the headphones it came with wont work, and neither will your usual ones. it will only play on speaker. the volume issue also affects media volume.
lot's and lots of issues with this phone, it seems as though my provider was trying to cut their losses by putting this phone on a special- IMO I think they're aware that there's something wrong with this model, but they are banking on customers not calling them out and paying for repairs- which ultimately cost more than the phone itself. extremely unhappy with this phone, I will never buy another nokia/windows phone again.

I'm going to return the phone, I want a refund- i wont accept another phone of the same model. Hopefully somebody reads this before purchasing this phone and making a huge mistake :(

Don't buy this "phone" worst phone I've ever had in my life, worse than my Nokia from 2003. I've never in my life been as frustrated with any phone like with this one, this thing has so many design flaws it makes me question why they even released it.its not user friendly, it doesn't run adobe flash cuz some dispute with Google. This phone literally forces you to use Bing because if you download the chome app, everytime you lock your phone the chrome App takes you back to the starting page, so ill be on facebook one minutes then if I exit to check a text message its goes back to google home page.its almost as if They purposely made the chrome app terrible because windows cares more about pushing their product than customer satisfaction. The volume automatically goes to 13 randomly and gives you a stupid warning about how loud music damages hearing which is annoying and can't be turned off. So laggy that its embarrassing, it literally takes more than ten seconds after you've pressed the button for a photo or video recording to respond. Finally the worse thing about this so called phone is the poor internet capability, I cant read attachment's my professors sent me, I cant see images on reddit or imgur, video freezes often on youtube, often crashes randomly while watching a video and takes you to the home page . returning to a previous page becomes a game of chance, cuz sometimes it goes back other times it deleted the tab your on and you lose the page and have to open a new tab.. No snap chat on windows , all the apps are garbage. be smart and buy and android phone

My son had a fit because I bought him this phone for his bday. He says its junk and I should return it. I'm using the phone now and the only problem I've had is waking the phone up. I had to keep pushing the button and finally got it to work. Other than that its a nice phone and I like how you can change the size of icons or remove them. Plus you can change colors of screen. I love the attractiveness of this phone.

Now upgraded to 1GB RAM and on half-off sale at my provider.
Windows 10 Mobile is out and can be installed on the Nokia 635 - 1GB version.
I'd much rather run Windows 10 than Windows 8.1 on my computers at home..

If this phone was as horrible as in the other comments the user reviews wouldn't average so high.
