Final Words

Designing an affordable phone is always going to have compromises. In this case, Nokia has hit on some reasonable compromises but gone too far in others. The lack of a proximity sensor was something that I didn’t miss at all, and the phone has no issue relying on the touch screen to know if it’s against your face for a phone call. This worked flawlessly in my experience, so it was the right call. The lack of an ambient light sensor was too much for me though, as I’ve come to count on it for using a device outdoors.

Another such compromise was the 512 MB of RAM, which is definitely one that went too far. It limits a good chunk of the app store’s game library from being able to be installed at all, which is just not acceptable in 2014. But again the storage of only 8 GB is no problem at all due to the included microSD card being able to add another 128 GB if needed, and Windows Phone 8.1 supports SD cards better than any other mobile OS.

The display is yet another compromise. Here we have a display which is almost at the top of our charts for accuracy, yet has a lowly resolution of 854x480. The lack of Glance screen support is another knock against it especially when the 620 of last year did include this feature.

One thing that Nokia nailed though is both the size and design. A 4.5” phone is a nice fit in the hand, and doesn’t run into any of the issues larger screened devices do with one handed use or being able to fit in your pocket. The phone is also nice and light, and with a great feel to it. I love the texture of the polycarbonate for this model with its matte finish. It never felt like it was going to slip out of my hand. The colors, as usual with Lumia phones, have a great range from pedestrian black to eye popping orange.

Using the 630 as a daily driver for a couple of weeks wasn’t a bad experience, and that says a lot about a phone with a retail price of around $160. Unfortunately for me, I found the phone had compromises in certain areas that were just too painful and would be issues for everyone. The first is the display resolution, which is just too low for 2014 and a device of this size. The second is the lack of RAM, which compromises the Windows Phone experience by limiting the number of apps available in the store.

I’ll admit my expectations were high when I received this phone after a good experience with the 620, and they were not quite met. Going forward in time, we generally expect progress and there’s not a clear case of progress here. As a successor to the 520, it does fairly well, and with the price of the 630 it’s much closer to the initial price of the 520 than the 620. The device is certainly faster than last year’s model and that’s a good thing, but the loss of features like the ambient light sensor and dedicated camera button make for a phone that’s not always a pleasure to use. If you don’t do a lot of gaming on your mobile device, you can get by with the 630. It’s always difficult to get the compromise just right, and in this case I think it’s very close but comes up a bit short in a few key areas. Price isn’t one of them though, and once again you get a decent smartphone experience for not a lot of money, but it’s just not the clear upgrade I was hoping it would be.

    thanks for the heads up. After updating my phone again the music player is performing as expected without the severe latency that plagued the older version.

    WOW a Windows Phone review! Awesome :D Ever since the vaporized 920 review, I've been waiting for one. (But that is probably more you not receiving hardware generally over anything else)

    Aside from that, excellent stuff as always Anandtech... in depth is awesome.

    "Edit" I also agree with your conclusion. The Lumia 630 is nice (especially as a 520 successor) but its biggest drawback (512MB Ram) is just really, really limiting.

    I feel it's a decent enough phone for $99, though if you can afford to spend more, you probably should.
  • skiboysteve - Tuesday, July 22, 2014 - link

    agreed. good phone for $99 but I havent seen it selling that low
  • noblemo - Wednesday, July 23, 2014 - link

    The Lumia 635 for AT&T GoPhone and and MetroPCS $99 until August 8. The MetroPCS 635 is being introduced with a $99 promotional price, also.

    Sorry, I inadvertently hit reply while editing. The Lumia 635 is being introduced at $99 for AT&T GoPhone and MetroPCS.

    Just a couple of corrections/notes:

    Page 2 - Under the Camera section of the specifications table, it reads lenght in each column.
    Page 6 - In paragraph two, you mentioned Windows Phone adding a battery saver last year. If I recall correctly, I had one out of the box on my Lumia 800 in early 2012 on Windows Phone 7.5.

    I wish Nokia made a hardware clone of Moto G (1 GB RAM, better display, camera) with dual SIM support at same price point that Moto G is selling at ... less than $200. One has to wonder why they are unable to achieve that, given that their OS is free (no licensing fees to M$).

    Excellent review.
    A small correction:
    Page 6 - GNSS section: "Hopefully the days of poor location tracking" ... are over, I suppose :)
