    It's a budget phone, with low specs. If the app store can determine that with 512mb of ram it will not be able to play certain games, why should it let you install it? It seems sensible to me that the store should stop you from wasting your time and possibly data allowance downloading something you can't play. Or do you believe it should ahve been spec'd so that it could play every game in the store? It's a budget phone, i'm not sure what you're finding unacceptable about this, and what has 2014 got to do with anything? I can buy a budget laptop that can't play titanfall, i can buy a budget tablet that can't play real racing. Is the issue solely that it will not let you install it, as opposed to just letting you install it to find it doesn't run? Reply

    From what I know:

    - Phones are not laptops, the difference between cheap to game capable laptops is the CPU/GPU, but the only spec that halts game installation is RAM, the GPU/CPU will run most games just fine.

    - Furthermore even the Lumia 525 (which is also a budget phones, released after 625, before 630) started to include 1GB of RAM, but Microsoft seems to be retracting back to 512MB of RAM, puzzling.

    - Thus: a few more dollars (for 1GB of RAM) would enable better experience on this phone, but why aren't they doing that, I feel this is a silly and ancient strategy.

    I have a Lumia 525 and a 920.

    1Gb of Ram really should be the minimum across all Windows Phone devices these days, the light sensor too,
    It's one of my favorite features on my Lumia 920 as I'm outdoors allot, the screen brightens up and the contrast and gamma increases so that sunlight readability is a non-issue.

    However with that said, many games and apps which have a 1Gb Ram version also have a 512Mb version, a-la. - Spartan Assault, so for some users, having 512Mb of Ram is a non-issue.

    If we go farther back though to the Lumia 610 on Windows Phone 7.8... That also has a light sensor, which worked fantastically, just unfortunate that the phone due to having only 256Mb of Ram and a single core processor was slow.

    I see that the Chinese versions of these (635 and 638) have 1GB. It'd be nice to get one of these if it were compat with US standards (LTE, etc). Reply
  • Brett Howse - Tuesday, July 22, 2014 - link

    Just to be clear I didn't say it was bad the store stops you from installing games you can't run.

    What's bad is it is 2014, and this phone has the same RAM as a Windows Phone 7 device from 2010.

    1 GB of RAM would open this device up to the entire Windows Phone store, so I can't see how that would be a bad thing.
  • bhima - Sunday, July 27, 2014 - link

    Its a budget phone yes... but its 2014. I DO expect a budget phone of almost $200 to play every game in the app store because, well, Motorola has already made a phone that can do just that for basically the same money in the Moto G. Reply

    Incredibly detailed and excellent as usual. Thanks for all the info. I'm glad you clarified why the 930 doesn't have Glance. It confused me, because I thought it was something MS was killing off with WP8.1. Good to know that's not the case. Reply
  • kspirit - Tuesday, July 22, 2014 - link

    Another thing I'd like to add is that the 630's display is not "real" ClearBlack. I have seen and owned devices with those, and my father has a 630, and this is most certainly NOT a CBD. It's marketed as such but there is no polarizer. Reply

    "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."

    Having ran into one major performance problem with using the SD slot on my WP8/8.1 phone, I don't know how true this is in general. Earlier this year I bought a 520 to play around with WP8 and to use as a music player when the risk of breaking it was high enough that I didn't want anything expensive.

    My music collection is currently ~60GB/11,000 tracks so I figured that with a 64GB uSD card (class 10) I'd be able to load everything on the sdcard and be good to go. Unfortunately I found that wasn't the case. I often shuffle over my entire music collection instead of drilling down to a specific artist/album. This turned out to be a major problem on my 520.

    With the original WP8.0 install attempting to do so froze the phone completely for between 5 and 15 minutes before returning to normal operation mode (at this point everything worked perfectly unless I restarted the phone or changed to a short playlist and then tried to go back to the long one). This problem affected XBox Music, Nokia Music and a few free players I found so it appears to be OS related. I tried upgrading to the developer preview build of WP8.1. This fixed the total phone lockup, but gave a new problem. With the giant playlist there is an ~30s delay between pressing next/previous song and the song being played changing.

    With both OS versions this wasn't a problem with small play lists on the SD card or when playing back from internal flash (limited to shorter play lists due to lack of space).

    I don't know if this is a problem with the SD implementation in particular, I'm using a class10 card so my card itself shouldn't be the problem, or due to the total size of the playlist swamping the CPU somewhere. I haven't tried filling the card up most of the way with images or video to see how well those apps behave; but this has left me rather skeptical of WP8's ability to effectively use a large SD card to replace internal storage.
  • silverblue - Tuesday, July 22, 2014 - link

    I'm not sure but it may be scanning all your music upon starting the app. Reply
  • DanNeely - Tuesday, July 22, 2014 - link

    I don't think so. The app launches as quickly as anything else on the phone does, and WP8 refuses to identify music/etc unless synced using an official app (vs just copied via explorer); and lists everything in the various category based lists (artist/genre/etc). The genre/etc based lists aren't possible without a full index already existing since (unlike artist) they can't be inferred from the file system.

    In 8.0, it was clearly doing some sort of pre-processing step before starting playback (but completely freezing the phone to the point of even hardware buttons being non-responsive is totally unacceptable); 8.1 doesn't do that, but has a major runtime performance problem as a result.
  • Kit Y - Tuesday, July 22, 2014 - link

    DanNeely is definitely right on this issue, Windows Phone 8.1 removed the on board music and videos to Xbox Music/Video that is separated from the core platform to allow more timely updates to the music player.

    However, the current music player do suffer from a lot of bugs and slowdown as reported on r/WindowsPhone quite often and major compliant of many uses.

    If I had the choice to make decision to balance cost and the features, I would forgo 4GBs of on board storage in exchange of ambient light sensor and 1GB of RAM, GG3 for Glance Screen and perhaps rename it to 530 as it seems to be a lot more appropriate given it's limitations and the similar launch price of 520 which we should see it to be drop to under $100 in many markets.

    I haven't tried any 3rd party players with 8.1; do you know if the architectural changes provide any scope for 3rd party players to preform better than Microsoft's? Reply
  • althaz - Tuesday, July 22, 2014 - link

    The music app is currently being updated pretty regularly and is a LOT better today than it was a month ago.

    That said, there's plenty of scope for a developer to make a much faster app - I'm working on one at the moment. My plan is to make something pretty limited, but I would personally prefer a very basic app that's fast over one that is fully featured but slower.

    the latest version of xbox music on WP8.1 resolves this exact issue. it now no longer scans for entire folders for music file changes every start up... it must use some indexing thing now. It also does scanning and updating in background if you're on wifi and plugged in Reply
  • Alexvrb - Tuesday, July 22, 2014 - link

    Yeah they've been making some improvements on the latest updates. Overall the memory card support in WP 8.1 is great.

    As far as "Class 10" goes... it's almost a meaningless label. Even having a UHS-I rated card doesn't really tell you much. Unless you have read/write and IOPs figures for the memory card in question, it might as well be labeled "random flash card that I hope doesn't blow". I have an ADATA UHS-I microSD card that is rated at 1400/100 IOPs random read/write. Most card manufacturers don't even release those specs because they are so bad.

    I really hope UHS-II picks up steam and they start releasing mSD variants and devices that support it. I've seen some UHS-II SD cards with IOPs twice as high as my card or better.

    I've got an iPhone 5s, but I've gotten Nokia 520s for two people now. I love it, they love it. It's really a great phone, and like my iPhone, there's just something pleasurable about using it. It (like real Windows) also runs a lot faster than Android on comparable hardware.

    The biggest issue I have with Windows Phone right now is that like Android it's stuck getting OS updates from the carrier. Microsoft needs to switch to an Apple/Windows model of controlling the updates themselves. That said, at least so far even the 520 is getting every single update Microsoft does...which I guess still beats Android save for the Nexus devices.

    My only complain with this 630 is the RAM. I realize hitting a $100 price point is kind of crazy, and the 520 runs fine, but still...1GB would definitely be the first upgrade I'd want for this.

    Considering I still carry an iPod anyway, I'd seriously consider a Windows Phone for myself if my iPhone died, just because of the price, though I think I'd go with the 6" model.
  • Wolfpup - Tuesday, July 22, 2014 - link

    Forgot to mention...I do wonder about the CPU choice. Obviously it works (and as mentioned you can't compare iOS or Windows Phone or even real Windows to Android as Android requires much beefier hardware to get the same performance)...but I am curious about using a quad A7. A7 supposedly tries to get close to A9 performance with a smaller die area, but then Krait is already A9+. Not sure it makes sense to replace 2 Kraits with 4 A7s...but oh well, I'm sure it's fine!

    Scary how much faster Apple's Cyclone is than everything else. Right now it doesn't even's mostly overkill for a phone, but probably not for the iPad, and certainly not for a more OS X-like iPad...
  • rgba - Tuesday, July 22, 2014 - link

    In the HTC One mini 2 review, Anand mentioned that Cortex-A7 actually delivers slightly higher IPC than Krait 200. Considering that, quad A7 running at 1190 MHz is a clear improvement over dual Krait 200 @ 972 MHz. Reply
  • ruggia - Wednesday, July 23, 2014 - link

    Higher IPC is meaningless when A7 runs on thumb instructions and is In-order, as opposed to Krait which runs full armv7 and is out of order Reply
  • extide - Thursday, July 24, 2014 - link

    Not true, A7 runs the full ARMv7 ISA, not just thumb. The cortex M series chips run thumb, but ALL cortex A class cpu's run full ARM ISA's. (ARM7 in this case obviously, but the A5x cores run ARMv8).

    It is in order, and Krait is out of order, but IPC is very much NOT meaningless!
  • tuxRoller - Wednesday, July 23, 2014 - link

    I guess you missed this:
    The Lumia 630 handily beats the Moto G in memory performance, but the Moto G wins the rest of the tests. We’re still looking at a performance deficit for most tasks with Windows Phone 8.1 which is something Microsoft will need to work on going forward.

    So. despite the Android VM deficit it still manages to at least keep up with, and generally surpass, win8.x. Can't wait till the new ART drops.

  • cashnmillions - Tuesday, July 22, 2014 - link

    I have the 635 after having an HTC DNA and then a Google Nexus 5. So far the phone has grown on me, there are definitely fewer features than some of those Android phones. Win Phone 8.1 takes a bit getting used to. It is simple though and runs pretty smooth. The thing I probably like the most is the size and feel of the phone when you hold it. I will probably switch back to android though in the next year and probably will get a compact or mini version of one of the bigger phones like the Xperia Z1 or S5. Reply
  • Alexvrb - Tuesday, July 22, 2014 - link

    A lot of the mini versions are gimped in terms of specs. Sony is usually better about that than most. Nokia has some good small phones that are higher end than the 6xx series. There's also talk of a 1520 V (smaller version) that might be good those those looking for something compact. Personally I'd be more interested in the 1820. Reply

    Thanks for the review, Brett. It's great to see real Windows Phone coverage return to Ars. I only wish there were some flagship phones to review. Newest one is the Lumia 930, and that's not even available in the US market.

    Oh how I wish they'd release a successor to the 1020. Hell, they could use the exact same camera module and it'd still be a winner. Just modernize the rest of the phone and address the 1020's chief shortcomings (white balance problems and lack of mSD).

    In spite of the #, this isn't really a sequel to the 620, significantly lower price point. If this thing was at $150 or better $129 then it's a solid phone for the $ but it's currently overpriced. I expect it to drop soon much like the 520 did, that thing came out at $129 but was under $99 within 3 months of release practically everywhere & often below that.

    512mb is definitely the weak point in this phone, kind of unforgivable and short sighted, hopefully now that MS has control they will but a stop to the 512 mb madness. Screen res is ok and performance is actually pretty good for the price point and Lumias are generally pretty well built vs competition in these cheaper market segments.

    Microsoft has to wake up and stop paying $ for Qualcomm in this market segment & get onboard with a cheaper SOC like MediaTek and spend the $ on ambient light sensor and extra RAM.

    Glance/Peek does not work on AMOLED screens properly. Either the design of the software is flawed, or the design of the driver (hardware or software) for the screen is flawed.

    Use the Glance funciton on the 1020 in a pitch black room. For the first fraction of a second, you see just the information displayed, as you would expect to on an AMOLED screen capable of only lighting up the pixels needed. But wait! after that first fraction of a second, the phone turns on the entire display to a dull, low-output greyish black. Why does it do this? No clue, I've asked Nokia several times, and never gotten a response. My guess is that they programmed the Glance function to work with LCD displays, so it's sending information to turn on the entire display, even when it's not needed.

    To be fair we're comparing it to last year's offerings. The 620 has more features, but is no longer available.

    Generally Nokia has done a good job of improving devices from 520->620->7... and up.

    It appears they are changing the starting point for this round though with the 630 being lower end than the 620 last year, and having a lower price to match.

    Until we see more of the products we can't know for certain, but it appears they are resetting the bar for this round, with the 630 being roughly equivalent to the 520, and it is priced similarly to the 520 when it came out as well.

    As for the phone itself, without a front facing camera and an ambient light sensor, I'd rather spend 30€ more on a Moto G. This really needs to be 109€ tops, not 130€.

    Pity you did not add the 1520 but just IOS and droid high end.

    I just amazes me that this BS continues

    Why not show the 1520?
    well on graphics it kills the competition.

    I didn't have a 1520 for comparison is the only reason. Reply

    If the 630/635 is the successor to the 520 why wasn't the 520 included in the performance results? It would be nice to see what the new model can do over the old model. Likewise, since I bought my 520 for $50 outright, no contract, and the 630/635 can be had for about $100, why is it being compared to the high end phones? I can see adding perhaps a single high-end for comparison, but I don't expect a $100 phone to beat out a $650 GS5 or iPhone 5S in a performance test. Compare other phones in a similar price range. Let's see the $100 Androids compared to this instead. That makes more sense to me. Reply

    520 = 620 performance-wise. Reply

    Stop whining about 512mb RAM, just go and see Lumia 520 vs Lumia 525 sales.

    See 525 on this chart? Me neither.
