Rumor: Windows Phone 9 will be a clean slate, again

Take this rumor with the smallest grain of salt, but we're hearing that Windows Phone 9, scheduled reportedly for 2015, will be developed almost from scratch to create an operating system that runs on both tablets and smartphones. This information comes from Mobile-Review's Eldar Murtazin, whose claim to fame is accurately reporting the death of Windows Mobile in August 2009.

Murtazin, who appears to have sources close to the matter, states that Microsoft has formed a group to plan and develop the OS to bring together both phones and tablets, and that this OS will likely feature a "different vision" of the interface. Whether this means that the Modern-style UI will be scrapped or just revamped remains to be seen, but it sounds like it will be different to the current UI in Windows Phone 8.

The operating system doesn't exist at this stage according to Murtazin, but the group tasked with planning the OS will have to form something by Fall so that the OS can be developed on track for a 2015 release.

Again, we're talking about an OS in the very early stages of development, so many things can change before the final release. However, it makes sense for Microsoft to intertwine the OSes for tablets and smartphones, so it's likely we'll see this come with Windows Phone 9. Whether the interface will see a major change remains to be seen; expect more news closer to the expected release date.

Why isn't this a possibility, perhaps they will go similar like they did with Vista, when they went with a clean slate after dropping longhorn.

My guess would be they would drop the WP api junk in favor of WinRT. And this might be the 'clean slate' they speak about.

If this is true it proves Microsoft pretty much lost all sense of direction and has no idea what they're doing anymore.

When I bought my RT on release date, I was very surprised that it did not use the same OS as Windows Phone, and that the app stores would be different. In effect, I expected an experience similar to that of iOS users, where my tablet would just be a big phone that doesn't make phone calls. From a development standpoint, it makes sense. Obviously, from a marketing standpoint, it makes even more sense, given the success of A$$le.

Microsoft is on a learning curve with Metro and still fleshing it out. I have no problem with a rewrite of Windows Phone as long as it's available toward the end of my contract!
That's probably the same of everyone.
Android suffers the same problem of capability versus hardware. It may not be such a bad thing that most Nokia devices seem to be built on the same core hardware fundamentals if you consider how much easier it is align the software when released.
When I had a Sony Xperia I was always frustrated that it took a year for them to update older devices. I'll bet Nokia doesn't have that problem. A good reason for an OEM to invest.

If it has the same kernel and is able to run Windows Phone 8 apps then this seems like a good thing to me.

I really like the modern UI but its very different on Windows and WP. They need to bring them more together. They could make both platforms look and feel similar but it would be even better if they are one platform.

The idea of taking your smartphone and putting it in a dock connect it to a large monitor is a very attractive concept. Microsoft would be lightyears ahead of the competition. For now that doesn't seem like a big advantage. But at one point in the future both Google and Apple wil lalso have to make a generation jump. The longer they wait the harder it gets. Microsoft already took a hit with WP7 and they are well under way to making it a reality. Might as well take the last step.

They will probably go Windows RT kernel with a phone shell hence the rumor that it is redesigned from scratch. Windows RT needs quad core, right? I guess the current windows phone devices will receive a bastardised 8.8 again while new devices will get 9

I made this point when 8 first came out. Apple bridges their phone and tablet together while keeping the desktop mainly separate. Microsoft took the other route of bridging desktop and tablet together and keeping phone separate. The ideal situation would have all 3 bridged, but in the meantime, I think Apple's model works best since it bridges the mobile devices and slowly adds to the desktop where needed.

Microsoft plans to end up with a single kernel for all platforms. It wasn't an easy task but Windows 8 made it a reality with the ARM kernel, while vista helped break down the kernel to something more modular and 7 added the performance.

It makes a lot of sense to have one OS that works equally well on smartphones and tablets. It seems that Windows-8, 8.1 was a first step in that direction. Now, what is needed is a new OS that works equally well on laptops and desktops. (Regrettably, Windows-8, 8.1 doesn't count.) There is no getting around it, regardless of the hyperbole, smartphones/tablets vs laptops/desktops are two totally different form factors and are oriented to totally different uses. One OS will very rarely work well for both, the UI being one reason.

Windows 8.x doesn't work well on Laptops/Desktops because Microsoft expected more devices with a touch interface by OEMs. And touch screens are expensive at the moment.

It only makes sense. Apple's iOS is set up like that. Google's Android is set up like that. So if Microsoft wants to compete they must make it scalable.

why would Microsoft do this? they already have a tablet OS....Windows Phone took a really long time to build it's ecosystem...

anyway, yay to convergence of any kind. Nay to a "different vision" of the interface - I like Windows Phone's vision of putting people first. In fact, I like Windows Phone 8 more than Windows 8.1.

If it was me I'd attempt to create a single unified Windows 9 that runs on all devices from phones through tablets and laptops up to the desktop. They're clearly going that direction but didn't manage it fully with WP8/Windows 8/RT

I heard Windows 9 would switch to an iOS kernel and iPhone 8 would switch to a windows Kernel....... there I can make BS up too

With the shift to the NT kernel I never understood the need for 3 seperate OS's.
It would have made more sense to make just two, RT and W8.
For tablets it would run RT, for phones it would run RT + added mobile functionality.
For the desktop it would be W8 + RT for Metro.

That way it would make more sense for devs as well imho.

Microsoft is a very big company that makes money from operating systems, if I had a big company that makes money from OS's then I would have 10 different teams writing 10 different OS's at any point of time, and if anyone comes with something brilliant, will release it to the public.

I don't see a rumor here, just a straight fact

Windows is not written by gods, it is written to be rewritten and rewritten over and over, not a big deal.

REminds me of MJF's rumor that win8 would RTM on Apr., 2012, and PT's rumor that win8.1 would be shipped Aug. 1......couldn't understand why people keeps blah-blah craps and said "from reliable source"....lmao.

Do whatever you want MS, but allow WP8 users to upgrade. Don't make it a WP7-like fiasco, lest you want to lose you steadily but slowly growing user base.

I'm sure our current WP8 devices will be upgradeable because 1) they share the same kernel now, and 2) they are supported past 2015 (especially now with the increased number of months of support).

I can see this very much coming true. I can see Windows Phone 9 being literally the next iteration of Windows which is scale able to the portable device. The thing is, the architecture is not changing this time so all WP8 phones would be upgrade-able.

I don't think it'll be a 'clean slate' but just a complete OS update (e.g. like updating your desktop from Windows 7 to 8). I think this will be needed in order to properly unify desktop/tablet/phone.

Also - I'm sure our current WP8 devices will be upgradeable because 1) they share the same kernel now, and 2) they are supported past 2015 (especially now with the increased number of months of support).

Can't wait :-)

Supporting an OS does not mean being able to updated to the latest OS....

That would perfectly explain why it's taking them ages to add features to WP8. The same happened for WP7 and Windows Mobile. When development slows down like that something's certainly up (but considering the kernel is already unified it will probably be some UI overhaul to make it more marketable against all those frankenandroid devices).

Ages? Umm... it's only been a few months since the release of WP8, and already there have been multiple rounds of updates released. Much more frequent than that of Android and iOS. They are moving much more quicker.

I wouldn't call 8+ months few months, and the number of updates doesn't say anything about what they add. Can you really call multiple recipients for messages, FM radio (announced and delayed since WP8 was released) and default camera lens features that are comparable to other mobile operating systems major updates? iOS 6 introduces tons of changes including a major UI overhaul and it was a yearly update just like the previous ones.

What would make more sense is that Windows RT would be formated to run on smaller phone screens and that the desktop UI be stripped out and eliminated altogether. This would make the code base far more scalable across all platforms and allow a user to use a phone with a KVM as a thin client for VDI and remote/virtual apps.

If MS reboots it again I think they will have successfully killed Windows Phone for good. If they pull another Lumia 900 I would be shocked if they ever recover.

If it uses the same kernel, then the only upgrading obstacle is the hardware. I wouldn't be surprised if only high-end WP8 devices can be upgraded to WP9. The low-end devices have less RAM and weaker CPUs.

SteveyAyo said,
They wont, already the same kernel

Doesn't mean all that much. WM6.3 devices didn't get 7...

The more intense work is in the device drivers not the Kernel. The SOCs are so similar between WP7 and WP8 (and should be between WP8 and WP9) that it will make next to no difference for the Kernel.

Redoing all the drivers will be a pain, but MS has no choice. They can't reboot 3 times

Except that WM 6.X devices ran on EC6, whereas WP7 ran on a custom CE6/7 hybrid kernel... It didn't make logistical sense to reflash every WP devices back then. This "rumor" aka completely untrue BS spewing from a historically unreliable source is irrelevant. WP8 devices WILL be upgraded to WP8.1/9 there is no dramatic kernel shift in the making.

My point is that and upgrade path isn't solely dependent on a Kernel shift.

I only came here to say that is they do another upgrade killing update they are committing suicide.

I don't think it would be a clean slate, but more of shift to move the WP to a platform where developers can develop their apps for both WP and tablet.

As for hardware, to be honest, I think by the time WP9 comes out, the majority will be ready to upgrade to a new phone - consider that you are in a two year contract and you've just purchased a new WP8.

I wish in 2015 Smartphone can run normal full fledged Windows 9. So that Microsoft can made only one OS unified. All X86 apps from 8 bit to 64 bit run in Smartphone. There also HDMI 2 / Diplay port 2 and wireless keyboard / mouse. So that it can fully functional like PC.

I doubt it. But if there's any credibility to this rumor you know the finns are giving elop the boot and releasing a lumia with android two weeks later.

As long as current Windows Phone 8 devices can upgrade this is cool.

EDIT: Although 2015 is far away. I wouldn't mind upgrading my Lumia 920 then. Just please don't screw over your customers MS (like with WP7 and WP8).

Nowhere in the rumor does it suggest that this will be a clean slate... It just suggests that the UI may change to support both phones and tablets... Which would be cool, but would still allow support for the current devices.

its bs for the simple fact that windows phone and windows 8 run the same kernel,and windows phone uses a subset of the winrt framework. there is zero logic in this rumor. Microsoft can complete the winrt api for phone and everything can run on the pc,tablet and phone,with no code changes at all.

Yep. But if you read the rumor, the rumor itself has nothing to do with the title... So, it's hardly what Neowin is trying to paint it as...

If this is true, I think we should be able to upgrade our Windows Phone 8 devices to it. WP8 and Windows RT run on the same core, and have similar hardware requirements. This new version won't be any different, so there should be no hardware limitations preventing us from upgrading. (Unless MS decide they want to change the standard buttons on the phones.)

Actually, making Windows Phone look like Windows 8.1 would awesome.

The concerns of people is whether our actual flagships (or not) will be upgradeable to Windows Phone 9. If they are, for my concerns, like if they build it from scratch 3 or 4 times again, as long as WP become better in overall terms.

Yeah, based on the same design, but I think with Windows 8 they did a better job (with 8.1). WP8 is a bit cluttered with all the tiles and lacks "style". At least, if they add backgrounds like in W8.1 and groups, it would be a big step forward.

I disagree. Windows Phone 8 is much more refined and consistent. There are too many sloppy UI constructs in Windows 8. Like the lack of/inconsistent use of the indeterminate progress indicator (compare the People app to the Bing app), the different-sized Back buttons... The list goes on. Look at an app bar, status bar, or pivot control in any WP7/8 app and you'll never see that kind of sloppy inconsistency. The Windows Phone designers put a lot more effort into making a clean and beautiful product. That's what I appreciated about the Metro design language, back when it was called that. The Windows 8 UI team just took the concept of tiles/squares and made a sloppy duplicate.

I'm talking about Windows 8.1, and yes, you're right in many points, as the People App and "me", but the Settings in Windows Phone? God please.

A move like this would probably be needed to make a mobile OS that could run on all mobile devices and be used / have versions for ARM and x86.

Gee I wonder if this will require another new set of devices... That's one of the main reasons I'm cautious to moving to the WP platform, I don't want to be left behind.

I should clarify before anyone gets the wrong impression. I'm fine with Microsoft doing this if it turns out to be a valid statement, I won't be fine with them constantly leaving customers in the dust by giving minor updates to their current OS and saying "Sorry, you can't have the new OS.". WP 7.8 was a great example of this.

Just as a bit of clarification here because posts like this do nothing but spread misinformation ( what Murtazin is known for)

The WP7 - WP8 issues were caused by a shift in Kernel... there isn't a new kernel to shift to. Windows 8 and Windows Phone 8 share the same kernel, no one needs to worry about a shift like WP7, despite WP7 getting better support than the majority of Android devices.

Almost certainly will mean so, it'll also mean that your existing apps you've paid into probably will need to be bought again and existing apps won't work due to api and platform changes.

A kernel change shouldn't prevent support of slightly older devices honestly.

Maybe instead of kernel shifting they are API shifting. The WinPhoneRT is currently only a subset of the WinRT and is only one of many APIs for WP (Silverlight, XNA, …).

If they move WP9 to WinPhoneRT-only and transform WinPhoneRT to be WinRT + phone-related classes (instead of the current subset BS) that could be a breaking change…

They COULD have done it, but it would have required you to return your device to be completely re flashed, the logistics on it were laughable so they left the devices behind... the marketshare was so low it didn't seem to be an issue

-adrian- said,
so the NT kernel should run without problems on CE kernel CPUs

The devices that ran WP7 ran the same CPU architecture (ARM) as WP8 devices, slightly older I imagine but still well within support. If you have anything to counter that point then please feel free to point it out.

It's a combination of that and a different set of minimum hardware requirements.

Anaron said,

Fair enough on that point. Still worrying when I'm looking to switch to T-Mobile and get a Nokia Lumia 925.

Even if Microsoft did distribute Windows Phone 8 to 7.x devices, most carriers would not have delivered it anyway. Look at 7.8, the Nokia Lumia 800 and 900, and the Titan 2 are probably the only phones that received it through the official channels. All those early adopters who paid $200 under contract for the Samsung Focus, HTC Surround, HTC Arrive, or Dell Venue Pro would be left behind anyway. As would the Focus Flash, Focus 2, and Titan 1.

And that 7.8 update was trivial in comparison to loading a completely new and different OS onto the device with a new kernel. Even if they did manage to do it without bricking devices, the Flash partitioning and file system layout are different, which would have likely meant forcing users to start over and reinstall all their apps and settings.

I think 7.8 made sense from a technical standpoint. I just wish they would have brought more of the WP8 optimizations/improvements forward like IE10 and the ability to remember more than 5 apps in the "Back stack." Even Kids Corner would have been a nice touch. I think if 7.8 was more functionally equivalent to WP8, WP7 users would have felt less-burned. I realize back-porting the new Start screen was a huge concession on Microsoft's part in their eyes, but the reality is that you won't build a loyal user base if you screw over your early adopters, who would otherwise help spread the word and bring more users to the platform.

The only reason it did for WP8 was because they moved to the Windows kernel... Now that's done so there is no need whatsoever. Something supported not just by Microsoft (Repeatedly) between the WP8 reveal and now, but also their lifecycle commitment...

And I would also like to point out that if you read the actual rumor (Or the story above for that matter), nowhere is it even suggested that this will be a "clean slate" outside of the ridiculously inaccurate title... Chalk this one up to click bait...

If you read my initial comment you'd see that I initially stated that I wonder if it *will* require a new set of devices. I know the difference between a rumor and fact.

WP8 requires a security chip in addition to the rest of the architecture. That was the reason that WP7-based phones cannot support WP8.

The NT kernel is completely capable of going backward, albeit without the security. Now, if Microsoft is dumb enough to make that mistake twice, then their ecosystem will be dead, but I feel confident that everything is now modular enough that WP9 will not have any issues running on my Lumia 920 (or whatever phone I have by 2015).

Wasn't MS touting a while back that you could write once and have it ported easily to any of the screens? Is that reality or not? I'm not a dev, I wouldn't know. But that's what they have been saying all along.

It's so far from the truth it's laughable.

Right now, I have an app that I wrote for WP7. I compiled it against WP8 with a few hours work, if that. But in order to get it to run on Metro requires an entire UI re-write, as well as changing some more API's. To successfully target WP7, WP8, and Win8, you need 3 different code bases.

And if I want to target the desktop - because lets face it, who in their right mind uses Windows 8 metro on the desktop - that's a 4th codebase. The code itself is all similar, but not similar enough where you can keep a single codebase.

I don't know what Microsoft is doing re-writing their mobile OS 3 revisions in a row, but if they can make an OS that requires a single codebase for mobile, tablet, and TV, I'll be happy. Even more-so if the tablet version works on the desktop.

They've been saying the same thing since the 360 was released. The closest we've come is XNA, but Microsoft killed that off.

Windows Phone and windows 8 apps supposed to have shared the same framework and be able to port with minimal effort. Except while it is possible to a degree, the platform for publishing them is different and not only that but there is no buy once, use anywhere mentality from Microsoft so developers don't see a reason to try and make an app work cross platform, it's extra effort to maintain two products with no incentive, certainly it's not giving a bigger user base, since it's two products and no additional revenue as most people will either pick one product to buy or none at all.

This is the point of the Windows Blue update from what I understand... Windows - WinRT - WP - XB1 will all be write one play anywhere (which is of course just a marketing term, you will have to make alterations to account for screen size and controls)

This is only this "bad" if you're not really trying.. Yes, Microsoft should have had "MobileRT" instead of Silverlight for wp8, but they probably will have something much closer for "blue" / 8.1 but in light of this - Its amazingly easy to use common tools, libraries and development frameworks to achieve similar functionality in apps on Windows phone 8 and Windows 8 from the same code "base".

I still use C# / .net and directX but I also use netadvantage controls and can easily build an app that runs and looks the same on .net, html5, asp.net, windows 8 and windows phone 8.

The beauty of .net, frameworks and controls is that you can have the same base code and use that base code in a project with specific design goals in which case right now wp8 and win 8 have unique design goals.. but the many control frameworks available dirt cheap (and free if you know where to look) make this almost too easy.

With all that being said, I think this prediction of windows 9 being entirely different to be complete BS. There is no way Microsoft would risk re-tooling once again for another framework/ui.. and I don't think developers would buy another retooling. Microsoft if anything is moving entirely more standards based with the adoption of more C/C++ standards, HTML5 & javascript as native languages.

The point is that developers can write the core of their code (all the logic) once and will just have a specific UI for each platform. Its the perfect example of the MVVM model. However, this is still hampered by different APIs still on each platform for some tasks. Just downloading a file or something simple might differ on each and needs to be custom.

That is the long term goal (With Windows 8.1 / WP 8.1 a large step in that direction)...

It would make sense for WP9 to continue that direction.

LightEco said,

True, but I still only maintain a single codebase for WP7/WP8/Win8. There are only a couple places where the API differs. Just use preprocessor directives (#IF/#ENDIF) to wrap those API calls. Write a single function that downloads files so that you only have these ugly preprocessor directives in a single part. It's very easy to get around these limitations.

Never heard of the guy. This could actually be pretty accurate though. MS has slowly made all of the interfaces the same between Windows, Windows Phone, and the Xbox. The next step is to actually make the underlying code identical, rather than just the kernel.

Not they will not risk that .. the marketplace has come to a screeching halt because it has become even more difficult to developer for windows phone ( you have to make separate apps for 7.8 and 8 ) They will end up loosing all goodwill they have if they do this. And then again the last 8 or so rumours this guy came up with have all truned out to be a complete lie.

The last time he got anything right was when he leaked Nokia N8 which is about 3 years ago.

Being a MS mobile OS user since the Motorola MPX 200 I can state that only once during the entire CE OSes era MS offered a OS upgrade. Technical reasons are not the only ones involved in the decision.
A simple excuse like a different positioning of buttons has been and could be used again to justify it again.
Said that if we could move to devices powered by 86 processors, running a scaled down W8/W9 OS, using Windows update ergo no more OEM and carriers involvement in the process I would buy it right away.

The thing that kept WP7 devices from receiving WP8 was greed. All WP devices use qualcomm snapdragon SOCs. It wouldn't have been that hard to change/update the drivers and recompile the new kernel for old devices. But sadly they wanted people to buy new phones and the existing user base was small enough to be sacrificed and left behind. They could have spent the time developing WP7.8 to actually port WP8 to WP7 devices. But they didn't...

Being a MS Mobile user since the days of the HP Ipaq, I do agree that MS has never had an OS upgrade. I always wondered why that was so and complained while still buying the devices. I now have a Nokia Lumia 710 that I had to buy after my HTC Tuoch Pro 2's keyboard crapped out while I was still waiting for the WP8 devices. I will now hang on to it until the T-Mobile releases the Lumia 925 and hope and pray that it will be upgradeable to WP9 if and when it comes out. Hopefully by then I'll be ready to drop another $500 or so, for another device.

But, I can say this on MS's behalf; the market has changed and Microsoft has learned from it. Forcing people to upgrade devices rather buy a new one when a new OS is released, is a thing of the past. IOS and Android has taught them a lesson or two.

Rewriting a view versus everything beneath the view are two completely different programming challenges.

Microsoft does not have another kernel to shift toward, and therefore they would be left with the task of rewriting the view. Even shifting a kernel is doable, so long as it is not dependent on hardware (e.g., a security chip as in WP8's case). There is no reason to add a second security chip, and the other hardware features are modularly supportable.

Besides, I have Windows 8.1 installed on my home desktop machine (not so much by choice, as I prefer full releases and I was running Windows 7; my Samsung 830 SSD just failed horribly with data loss this Saturday, and I needed to get up and running as quickly as possible), and I must say that I am happily surprised with the experience's subtle improvements compared to Windows 8 (on my Surface Pro).

Multi-desktop support is great, and I love having the taskbar on both screens with the running application optionally snapping to the screen's taskbar that it is actually on, which makes it easier to locate (once you get used to the change).

Anyway, my point is that I do not want the tablet/computer experience to converge with the phone too much. I enjoy live tiles on both (vertically on the phone and horizontal on tablets/PCs), but beyond that not much else really needs to change as the apps are controlled on an app-by-app basis.

Now, maybe they can both share a notification center of some sort and a quick-action list for enabling/disabling things (e.g., Bluetooth and WiFi rather than requiring a live tile), but even then the view will almost certainly scale completely different between the UIs of phones and tablets/PCs.

Not only that, but the title appears to have absolutely NOTHING to do with the copy... Now THIS is click bait. lol Nowhere does it even elude to the fact that this rumor even suggests that this is a "clean slate"...

Rumour has it that Windows Phone 9 will run Android underneath. Apparantly Android already sports these features, with the same OS being capable of running equally well on both phones and tablets, and apps written for one platform also run seamlessly on the other.

Totally the same thing. It's not like nerds weren't ready to burn down buildings and kill children over the switch from 7 to 8.
