'Features may vary' on 512MB RAM phones with Windows 10

The questions around the Windows 10 release for smartphones continue and today, Microsoft's Joe Belfiore, has taken to Twitter to answer a few of them. Namely addressing 512MB RAM devices and where they stand as well as how wide the initial Technical Preview will be.

"Hey all: we ARE working on Win10 for 512MB, including 520. Our ambition is to make #Win10 available for these devices but features may vary""Timing for various phones may be variable as well. When we first launch insider program, it'll be a subset of phones with more coming latr""Also, we're on track for Insider build coming "in Feb" as Terry said at our 1/21 event. We need to complete internal testing 1st, hang in!"

The last one goes without saying, but Belfiore is naturally seeing the furore around the incoming preview and that there are still more questions than answers. The middle point is interesting, if not totally unexpected, and confirming support for 512MB RAM devices will no doubt comfort many. "Features may vary" could mean anything at this point, but Microsoft will surely give it a damn good try.

  • So hyped.
  • Might even seem faster, who knows.
  • As long as we get something. Google would have just ignored all of those low end phones
  • Omg you're so right though. So nobody will have a reason to complain because of least features at least you're getting a update unlike google.
  • I have reason to complain. My Surface RT AND Surface 2 won't get it, and those are Microsoft's own tablets, even the latest one. Meanwhile Microsoft develops a "special version of Windows 10" for Raspberry Pie 2. And it's not like Microsoft said "we won't develop for ARM anymore" because they have to work on phones, and they say it's the same Windows everywhere, but just my tablet should be left out in the cold...so it's not just Google that ignores everyone. When almost all of Windows Phones sold in the world have 512mb then Microsoft would essentially be doing the WP 7 to WP8 thing to everyone, if they ignored 512mb RAM devices! I guess it's my own fault for trying to support MS's endeavors in different fields.
  • This^! Sadly early adopters get the shaft.
  • Lol, RT.
  • Whenever I hear someone say something like "Lol, RT" I immediately conclude he doesn't have the slightest idea what goes on in the tech world. RT is only bested by full Windows 8, and that's it. Bring any iPad or Android devices its way and they are destroyed before they can begin to compete. Here is what happened: normal, non-technical people got confused with RT and some semi-technical people (maybe like yourself) actually followed those who didn't know what's going on. That's how, for example, people buy the iPhone 5s instead of the LG G2 and also pay almost double the price; while G2 DESTROYS iPhone 5S in every department. So yes, enjoy your "iPhone" and come out with "Lol, RT". That makes you look like you know something /s.
  • Exactly. Unless your absorbed in the ecosystem and only want one OS , RT had outperformed any mobile tablet OS. And while I wouldn't get another RT because of lack of interest, the only other option I would go is full Win Tablet. Posted via the Windows Phone Central App for Android
  • ....so my 2520 is doomed too? Is it official?
  • I still fail to see what there is to complain about? First off, MS announced that some of the features will come to the RT, second, does your tablet stop working when Windows 10 drops? No, so you get to enjoy what you have been using since you purchased it. Why do people feel so self entitled that they expect to get every new update spoon fed to them for free?
  • I also have a RT tab, but I am also thinking 'how long will someone crack W10 for Razz pi on a Surface RT tab. I'm will to bet a few months
  • Exactly! I hate how when I had an HTC, I was stuck at Ice cream Sandwich. They abandoned a ton of users...
  • Are all you guys fucking retarded? Google does not supply updates to every Android phone out there. They provide the updates to OEM'S and they provide the update to their devices. Posted via the Windows Central App for Android
  • I hate it when people think its the company's fault (Microsoft Google) Microsoft sent windows phone 7.8 to OEM's and do you think they gave a shit, and the few that did care Carriers ignored it. T-Mobile has windows phone 8.1 up there ass for the Lumia 8xx and don't give a shit either. Posted via Nexus 1520!!!
  • That's what we're freaking referring to Mr. HateSpeech. Your blind if you don't notice Google's lame as crap tactics.
  • More to be precise its google - cpu oem - then phone manufacture
  • Way to use people with developmental disabilities as an insult. Stay classy.
  • Its a metaphor my friend, very common actually. Way to use a lame comment as an insult. Stay outclassed my friend.
  • Actually the word retarded is not a metaphor, nor is it a simile. It is could be considered an adjective or possibly an adverb when used to describe an action. Common? Yes, it is commonly used by grade school children who do not know any better.
  • I was referring to being blind actually. Making "retarted" jokes is very uncool and low-end to say.
  • Using the "R Word" is a great way of showing your intellegence. Thanks to the others on here that noticed. The comment should be removed.
  • I hope that was sarcasm but yes, agreed, the comment should dissapear.
  • Saying the "R-word" is retarded. Don't PC the comment to dismiss it.
  • I hated HTC from the point when they announced the HD7 was NOT going to get the 7.8 update. Flashed it myself within the next few days.
  • I hate the OS names, its like a sick twist on Willy Wonka
  • even microsoft abandoned us upgrading wp7.5 to 8
  • Well, if that didnt happen, then one microsoft vision wouldn't of happened, and WP would still be useless. You still got more updates than msot other phones from WP7, quit whining...
  • That was a hardware limitation. They accommodated as much as possible with 7.8.
  • Ok, no, it wasn't an abandonment, it was Microsoft getting with the times and changing from a dead kernel to one that has all of Windows 10 tied together. It's just going to get better from here on with One Store on Three Screens.
  • Man you're really holding tight to that hurt. You gotta let it go bro.lol Move on with life.
  • To whom are you referring?
  • I was referring to the guy still whining about how Microsoft abandoned us with the jump from WP 7.5 to 8. Posted via the Windows Phone Central App for Android
  • That was one and one time only really. WP8 is a lot safer too though.
  • I know and that's why I said he has to let it go. I was hurt too when it happened but 7.8 was enough to hold me over until I got my old Lumia 920 which I still have. Posted via the Windows Phone Central App for Android
  • I think from now on, WP will never have a device that gets hold back unless it would be a hardware thing or what not. They're pretty fair as far as OS updates unlike Apple (in general) or Android (OEM mainly).
  • Nokia upgraded all their phones to 7.8
  • It's was because 7.0 devices did not have the power to run 8.0+. They got you as close as they could to 8. Posted via the Windows Central App for Android
  • Actually, it wasnt because of hardware limitations, 8.x isnt mor edemanding then 7 (well.. it may be, but not in a way that would really bog down a WP7 device) it was because microsoft changed from the CE kernal to the NT kernal, WP7 devices werent made to run that, and yea, it is possible to get WP7 devices on the 8.x update, as certain sites have figured out, but it wouldnt of been worth microsofts effort, that would basically require flashing the entire bios of the device, everything would need to be re flashed, which is NOT a simple thing, and much could go wrong, and its such a high risk of error, microsoft releasing that update would essnetially kill atleast 40% of peoples devices
  • Buy 520 then, or another low-end device, they are not expensive
  • except that one won't get win10, and the Lumia 435 will get it and is generally a far better option
  • HTC moved away from that. They learned from their mistaks and now they're one of the first OEM's to push Android updates now. Not only that, but they gurantee updates for at least 24 months now.
  • HTC might be a bad example. Every HTC windows phone was abandoned when it came to updates. Then there was that whole W7 beta testers that couldn't get W8. Just like the people with cheap phone will get W10 but it'll probably be like W7.8. All you going to hear is complaints. Posted via the Windows Phone Central App for Android
  • FFS!!   STOP SPREADING THIS RUMOR
  • Then again, majority of WP out there are low end. This is somewhat different from Android where the share of mid and high end is probably significantly higher. Plus is it due to Google or the OEM or even the carrier?
  • I would argue that the majority of androids are lower-end. The higher-end phones just get more attention. And it's probably some of both. I'm pretty sure I've read that the vast majority of android phones won't get lollipop because google won't update them. But I'm sure there have been instances where google pushed out an update but a carrier blocked it, too
  • Windows phone and Android are pretty comparable when it comes to the percentage of people on low end devices
  • All Android are low end because they don't work without lagging :D
  • BS Cry me a river if you want but then build me bridge to get over it... Posted from my HTC M8
  • LOL that's a fresh new way of looking at things!
  • +1
  • My wp7 has 512mb....
  • .-. k
  • Don't mention specs on wp7 we got our chips nearly two years late look at the Lumia 900 chip and what Samsung released that year we finally started getting them in the same cycle
  • Unfortunately for you, Microsoft said they would support WP7 phones for only 24 months and it's waaaayyy past that for all WP7 phones. But my HTC Radar on WP7 still works very well (other than the battery) so it's all good!
  • There are way too much use of the word 'hate' in this thread
  • #1520.3 Master race! W10 will hum right along on my device
  • Im sp ready! I don't care what phone its on. I need the developer preview here this week. Lets hope it arrives this week!
  • So, a low-end device will not get all the features? That is to be expected, no?  - The low end Lumias do no not have SensorCore, Glance or 4K enabled hardware so they won't get those features.  - This is exactly how Apple handle their OS upgrades. The oldest supported device gets the OS and most of the features, but not all of them. (iPhone 3Gs got Apple Maps, but not Flyover / 3D view, etc. when the features were added to the OS).
  • Humpf...
  • As expected?
  • Pretty much. Can't please/quiet some people though until it comes from the horse's mouth.
  • I think the concerns were genuine. I mean, there were talks of not necessarily all WP8.1 phones getting W10. The obvious thing for being excluded is 512mb RAM. 
  • I thought the concerns were more carrier-based. Like, your phone "can" get W10, but Verizon might not approve the W10 upgrade. Cause MS already said all 8.1 devices would get 10
  • I wish, its mostly just a bunch of doom bringers who saw a "system requirements" link in the insider app that leads to nowhere, and everyone started going "herpderp microsoft supid herpderp they better support my phone herpderp herp herp based on absolutely nothing but a dead link.
  • So they are pulling out the truth, bit by bit. 512mb ram will get something like wp 7.8. Ok. I will stick to wp 8.1 and then get an android. As there isn't any advantage having a wp now. Why in the world they keep making 512 ram devices if they cant support their own OS? It will happen the same as wp7. People couldn't upgrade and the wp hate started. W10 doesn't look any different from wp8 except for some extra features(and I'm sure missing features too, and yes, I'm talking about the final version, although we still don't know which) so I don't really see why it won't support it.
  • They have not released a single 512mb ram phone since the 635
    535 532 and 435 all have 1 gb of ram...
  • Did you hit your head or something? Since when does "features may vary" mean that they won't get windows 10? they will get it but understandibly they may not be able to do everything that phones with 1 GB can. To compare this to 7.8 is just plain stupid.
  • First it was all would get w10. Plain and simple. Some days later it's only select phones were getting the preview. Alright with that. Then "features may vary" .this is very suspicious. what's next? Two different w10 versions? A covered-up w10- named OS with less features? Ok...let's wait and see if MS learned from its mistakes...I hope they did
  • oh shut the fuck upm you bloody moron, just stop, go away. if you wanted a phone that could do everything then why in the fuck did you buy a budget phone, buy a real phone or quit your god damn bitching.
  • That about sums it up...
  • Wow.....
  • Ding Ding Ding........ We have a winner Cry me a river if you want but then build me bridge to get over it... Posted from my HTC M8
  • THIS^
  • That made me lol, it's soo true though
  • My God shut up you whiner...!
  • He may has been drinking alcohol. lol
  • Ok. Then go buy some low end Android device that was released the same time the L520. I'm sure you'll get updates until the end of 2015 with those too, right?
  • Are you being serious dude? Here is a quote from MS: "All Windows Phone 8 devices will get win 10." Stop being so ignorant! No, "features may vary" is not suspicious, it literally means that some phones with 512mb RAM will miss a couple features but it will still be W10. Did you seriously expect that your BUDGET phone would support every single feature coming to W10? It's not a budget phone for no reason.
  • http://lumiaconversations.microsoft.com/2015/01/22/the-lumia-you-love-ge...   "Like any upgrade to a new platform, not every phone will upgrade or support all possible Windows 10 features, and certain features and experiences will require more advanced future hardware. Our goal is for the majority of the Lumia phones running Windows Phone 8 and 8.1 to join the Windows ecosystem" 
  • Exactly DennisdvD. My iPhone 4 updated to iOS 7, but it didn't get every feature that my daughters iPhone 5 got, such as panorama in the camera, Siri, screen mirroring etc. However what it did get was worth the upgrade and I still use it as my daily driver. Posted via the Windows Central App for Android
  • Its not just the ram thats the problem its the storage & CPU thats paired with these 512mb devices
  • Jumping to conclusions. If they were going to do a WP7.8 update for 512mb phones they wouldn't have said you were going to get W10. You'd get W8.9 or W9.9. You will get W10 like everybody else with only a few features not available like how only the 930/1520 get Hey Cortana or how the 930 doesn't have Glance due to hardware restrictions. None of which are huge deal breakers in any sense of the meaning. I have a 925 and a 930. One has Glance, one does not. One has Hey Cortana, the other does not. If you want to get all the fancy features and bells/whistles then shell out the money like everyone else and get a better phone or deal with what you got. Complaining about your 512mb phone not getting all the features as better phones is like complaining your cheap phone only has a 5MP camera and not a 20MP camera. You get what you pay for.
  • Part of the frigging problem is that the morons keep selling the BS that spec's don't matter with WP... Spec's matter wither they think so or not ........ The better the spec's the better the experience the better the chance of full future functionality Cry me a river if you want but then build me bridge to get over it... Posted from my HTC M8
  • Why don't you drown in that river?
  • +929
    That reason pushed me away from the L1020, I knew that the aged SD S4, wouldn't support updates as good as the SD 800 in the Icon does, and I love the camera on the L1020 but I was real choosing. You get what you paid for, and timing in technology is like a lightning.
  • Go right ahead and pick up an Android because that is probably the only platform that leaves behind a whole swath of phones that don't get updated to the latest and greatest. LOL in Android you are diced a greater chance for being left behind than in anywhere else.
  • Great news! Hope all low ends can get the features like pull down to reply and action center
  • Of course we get those.
  • That's already In wp 8.1...w10 is supposed to be an upgrade not a downgrade...i hope MS understand that.
  • The people who buy these low end pieces of snot should've known from the get go it may not run
  • I meant updates to action center like expanding the icons
  • I don't waste my time with low end garbage anyways
  • Whoa, calm down big spender...
  • So cashing out $130 for a 535 instead of $30 or so for a cheapass phone makes you a big spender?
  • I don't recall a Lumia 520 being $30 everywhere....
  • When i first got the 521, it only cost me $1 at one of the WalMart stores near me. Traded it to tmo for a 925 and got $5 for it and it cancelled out a migration fee.
  • It's $30 on Amazon right now. I bought one a little over a week ago as a backup device in case something happens to my Lumia 920 our my wife's 1020 again. I've been playing with it and I've been on awe at just hire well it performs compared to the higher end phones. I was also hoping to use the 520 to try out the Windows 10 Technical Preview before taking the plunge on my 920 daily driver. I just hope the low end preview doesn't lag way behind that for the higher end phones.
  • No, but stating that the majority of wp's out there are low end. Many of us can't keep up with the carrier deals to get the high end phones at a "cheap" price.
  • Yes, if you aren't living in 'Murica. There are countries in the world where average pay is 300$ a month. There are a lot more countries where average pay is a lot less than that. That's why 520 is most sold phone, not the 1520.
  • Why waste money on a do it all phone when a low end does all you need.
  • This. That's why I got a L720 in first place.
  • Why not? For us rich folks they make great dollar media player gifts for friends and family. Really? Perhaps be a little less douchey in your posts.
  • Well, I have a low end (625) and it's perfect for me. I wouldn't spend too much on Windows Phones for now.
  • Me too!
  • I also have 625, it is not low end at all. If wp10 TP available, I will try.
  • The 925 was high-end when I bought it but that didn't stop me from buying the 625 because I loved it. I sold it to a friend when I finally bought the 1520 quite cheap through a promo. The 625 is a beautiful and very capable phone and my friend loves it.
  • In my country a unlocked 520 is over $200. Just bought my 630 for $300. 720 is around $500. 925 and 1020 are well over $800, and the 530,535,730,830 1520 and 930 don't even officially sell yet. So always keep in mind not everyone can buy high end.
  • It's common sense. I'm surprise by his comment really.
  • What country are you in?
  • Wow! That's expensive
    Are you on DR???
  • Wow that's surreal! There are still brand new unlocked 520 being sold in my country but they're all under $100, and the brand new unlocked 630 sells for $150. 
  • Lol
  • Thank goodness because the 521 is my only test phone. I refuse to test the software on my main driver.
  • Yeah, it is good news for folks that don't want to take a dive into the deep end with the preview.
  • But it looks like even the L 520 will get Windows 10, maybe it will not get the TP build.
  • Just keep it fluid on my 520
  • The first round will be 1520 and 930.
  • I expect the 830 and M8 will be included in the first batch. They are the newest "high" end devices.
  • If the 830 gets the update, then why not the 730/735. They both have the same amount of RAM and the same processor?
  • I believe the 520 will be in the 1st batch. We're all guessing of course but the reason I believe it is because the 520 is still the most widely used phone out there and will therefore be a good showcase for how well W10 will run on an older 512MB model.
  • What did you expect? Cit.
  • My 630 is ready
  • Currently the best 512 phone there is
  • I'd like myself a 720 personally
  • +630
  • +630
  • +630
  • +630
    hope we have some advantage over other 512mb phones ;)
  • You get the flashy Windows 10 load screen :)
  • +625
  • +630
    The best 512 ram wp :)
  • I think they are gonna include 630 in the first batch cause Gabe Aul said they are gonna release the first build to some 512r phones so hopefully we are gonna get it
  • I hope the majority of 1gb ram Lumia gets in on the first preview.
  • Me too. I'll be quite disappointed if my 925 isn't in the first wave.
  • +925
  • Thinking of getting a Lumia 735 as a spare handset and test unit for W10... Anyone have experience feedback on the 735 that you could share please?
  • WinCen have an unboxing video that passes for a review of sorts, it should give you the info you need.
    To sum it up though, it has the unibody polycarbonate looks of the Lumia 920/1020, but has a removable back/battery and expandable storage. It has the very important 1GB ram, 8GB internal storage with micro SD card support, Snapdragon 400 (roughly equivelent to the previous generation's top end processor), 720p display with Nokia/Microsoft's clearblack display tech. All in all it's a very nice midrange phone that SHOULD give you a pleasant experience dealing with the Windows 10 preview. Just don't expect it to have the flawless WinPho 8.1 experience you may or may not be used to :)
  • Thx very much that's a big help, I'll take a look at the unboxing vid. I'll be using it on WiFi only around the house for a bit here and there to see when 10 becomes daily driver worthy. Thx again :)
  • Not really helpful but I love that design.
  • Yeah thx I'll take a look :)
  • I bought a 735 a month back. My Lumia 920 had reached a state where I had to charge it thrice a day. Using this till Microsoft launches a new flagship phone. I have been pleasantly surprised by this. Very light and impressive performance. Battery now lasts for 1.5 days with the same usage as 920. Added bonus is SD card slot.
  • Got a 735 and a 920, apart from the camera and touch buttons feel the 735 is superior, performance, weight, battery life, brilliant device, just wish the 830 had the same design, hate the aluminium body, only reason I haven't replaced the 920 so far!
  • The pricing of the 830 makes it quite a joke. It's positioned way too close to the 930 in price range, and the 735 is close enough in every aspect outside the main shooter that it's a far smarter buy. Also, a few people I've seen opinions from actually prefer the 735's camera, so there's that too.
  • Ah yes, unfortunate but quite true about the pricing of the 830. I would have bought it as replacement for my 925 had Nokia/Microsoft positioned it with better pricing.
  • It's what I'll be using...
  • I'm using 730 ie non 4G version
  • A great "pufff" of Windows 10 announcement
  • My sadness is with my Surface 2 not getting Windows 10. Same with my wife the the Asus Transformer T100, I'm really disappointed. Not looking forward to the Windows 10 editions one bit. It's sad that Microsoft will leave us with some useless tablets. Not well planned Microsoft!!
  • Assuming the Asus Transformer has the Intel Atom inside it, it will be upgradable to Windows 10. The only reason the Surface RT/2 isn't is because (I assume) it uses an Nvidia Tegra chipset. Unfortunately, I imagine the Surface team probably weren't aware of the direction Windows 10 was going. It still seem Microsoft's bad old habit of poor communication between departments is alive and well. Hopefully that stops happening going forward.
  • yea, it seems to be getting better though slowly but surely 
  • Rubbish, the Surface 2, which I own, is a great device. It's RT/Arm so wont run full W10, but will benefit from some functions in W10. I'm looking forward to the updates.
  • RTs are still getting Windows 10 RT. Obviously not full Windows 10.
  • actually, it seems more like they are getting a "7.8" situation, while they are getting an updat,e and it may be big, it wont be what everythingf else gets, and it pretty much means this is the last update they will get.
  • Your bringing in the 7.8 situation is unfortunate and makes you're comment sound like FUD because you very well know that the change from WP7 to WP8 involved a gargantuan change in OS because of kernel shift. There's nothing like that involved in the the upgrade of Surface/Surface2 so your use of 7.8 to 8 as reference is absolutely misleading.
  • No, its not, no ots not a kernel shift, but they've said they will get *an* update, they specifically noted that, implying that windows 10 isn't coming in full
  • How is your tablet useless? They aren't taking away functionality. Their not pushing an update to you that melts your tablet. Yeah it sucks rt wont get 10 but calm down man!
  • I have installed the Technical Preview in Asus T100, and quite pleased with it (minor UI glitches) what's the problem?
  • Why wouldn't the T100 get Windows 10? It runs full Windows now not RT. I have the preview I stalled in mine now and it works just fine.
  • Old devices were not designed based on future software releases. It sucks, sure, but it's going to happen somewhere. Even Apple can't avoid it.
  • Thank you, people are so blind to anything that doesnt benefit them..
  • Surface 2 really only needs the Windows 10 App Store
  • What if you get something like windows RT 10
  • Give us a realease date :|
  • I don't think it's going to be realeased, but I am hyped for it's release. c:
  • You don't think W10 preview will be released. Boy, you're some kind of special...
