Dell reportedly cooking up a dual-screen device with Windows 10 on ARM

If you live in the Microsoft bubble, one of the most hotly rumored devices is Microsoft's Andromeda project, a foldable dual-screen device that the company has been speculated to be working on for some time. Microsoft certainly isn't alone in its efforts, as, most notably, Samsung has been reported to be cooking up something similar for months.

According to the latest rumor, however, Dell may be getting ready to throw its hat in the ring as well.

German blog WinFuture.de now reports that Dell is working on a dual-screen device under the codename "Januss." According to the report, Januss has been in the works since last summer and is expected to run on the Qualcomm Snapdragon platform. Other tidbits the device is rumored to include are USB-C, several cameras, and LTE connectivity.

The report doesn't cite any potential release timeframe and, ultimately, the prototype device Dell is said to be working on may stay in the prototype stage without an eventual release. Still, it would certainly make sense that, if Microsoft is indeed working on a dual-screen device, it would want its hardware partners in on the action, too. After all, Windows 10 on ARM seems to be a focus for Microsoft going forward, and Dell's rumored device would be another on the market.

  • Will all of these coming dual-screen devices have telephony too?
  • Probably not. Haters will dub it as another Windows phone attempt. Microsoft needs to stay away from that mess and sell this as a pocket pc.
  • What makes you think people will carry two devices in thier pockets?
  • As opposed to carrying a phone in their pocket and lugging a surface pro/Laptop around? If a device offers the same functionality as my core M powered SP4 while being more portable, I'm game!
  • Can dual 6" screens have the same functionality and productivity of a 12.6" Surface Pro? They certainly aren't as big and the keyboard is probably going to be separate and/or very small. I feel cramped on a Surfacebook and even a 10" machine is basically unusuable for any productive tasks. It is tough to find a decent 10" laptop for a reason. The ARM processor is going to limit performance and compatibility too. What will you really gain from such a machine? It will suck as a phone since it has no phone ecosystem to speak of and it will suck as a laptop since it also will have limited ecosystem, small screen, and no keyboard.
  • Oh dear, you have no clue what really is limiting performance. For a 6 inch device, the only thing which is limiting performance is thermal headroom. And since ARM processors are much more efficient than Intel and AMD cores the only correct conclusion is, that when going with ARM you maximize performance for such devices. Period.
  • I know what you are saying, but we are talking about Windows. ARM will limit performance and compatibility compared to an Intel machine like the Surface Pro this would have to replace.
  • you're not making sense. ARM is approaching good performance quite rapidly. The upcoming S850 for WOA has a significant improvement over 835, then there's S1000 that is apparently being reported. ARM PCs in emulation for S850 are already reaching Intel Pentium N4200 So ARM is getting there and more improvement will further reach Intel levels. Also this OS will no run ull Windows 10 . It's likely going to run WCOS on ARM, which Centennial apps are going to be virtualised.
  • Easier to carry a laptop in a bag than a foldable tablet in a pocket (especially if you already have a phone in a pocket), people already complain about 6 inch phones, imagine a device that's twice as thick.
  • Speak for yourself. I wouldn't mind to have a dual screen or quadruple (le's think outside the box) screen portable device in a 6 inch form factor comparable to the MS courier idea. I would not mind to revert to a flip phone to make calls if that device would be available to sketch, draw, jot ideas, do creative stuff over and above the boring apps you now find on smartphones, and yes I would love to have a small pen with it to draw comparable to the Surface Pro pens
  • What I said wasn't subjective, it IS easier to carry a laptop in a bag than a foldable tablet in a pocket, I'm not saying it can't be done, and I'm not saying people won't want to do it. However I also wasn't lying when I said that people did, and still do, complain about the size of 6 inch phones. I owned the 1520, so I know big phones, but the fact of the matter is there were pants that I couldn't fit that phone in my pocket, so I had to adapt to it. And yes people could too, but if the device isn't telephony, and you need to put it in a bag anyway (in certain circumstances), why wouldn't a person go for a more powerful and versatile laptop?
  • I carry two devices now, a Pixel 2 and a Samsung Tab A. I love to switch out the Samsung Tab A with a Windows 10 foldable device.
  • The dell reportedly will have phone capability.
  • And if that's true, then Dell will get my business. No phone, no deal.
  • Me too Whodaboss.
  • 100% agreed. Word count.
  • Yet if it isn't marketed as a phone, the average consumer won't see what it really is. The confusion will cause the vast majority of people to dismiss it before it even gets off the ground. Tell what it is that average consumers will understand. Otherwise, the confusion will blind the real message. A more powerful smartphone is what people will understand. Not a mini laptop, oh yea and by the way it can make phone calls.
  • It will very likely depend on how pocket-able they are. Not all of these foldable devices will be small enough to fit in a pocket, in which case it probably doesn't make sense to include telephony capabilities. Pretty sure they'll all have LTE, though.
  • I've maintained from day one that the first generation of these devices would be data only.
    Second generation would support VoLTE / VOIP. WalkingCat (@h0x0d) has confirmed that the telephony APIs have been added to the Windows SDK so who knows. With the news of a Snapdragon 850, I'm thinking it'll lack the CDMA/TDMA/GSM/HSPA bands for traditional telephony/sms/mms. This story however also gives credibility to the other things WalkingCat (@h0x0d) found in the SDK bits. "Andromeda-Device" and "AndromedaOS" being listed as two different classifications. One for MS built device, one for OEMs.
  • I'd only say telephony needed to be included this, if being a WM10 user, I hadn't known how unreliable the telephony functionality in first-party devices is, that Microsoft neglected for 2 years now and had not have a chance to work on in the meantime.
  • They could try to sell an 8" tablet with a Bluetooth cell phone headset, but you'd have to stay within 30'-40' of the device. Or, you could just hold the 8" device up to your head. I'd love to see that out in the public. :)
  • " Or, you could just hold the 8" device up to your head. I'd love to see that out in the public. :)" Give them the option and and they will. Look at all those people taking pics with their ipads.
  • I dunno, a bluetooth earpiece and proper voice commands can make it work over a distance for telephone purposes
  • I think it being a phone is a no brainer. use a Bluetooth headset and give'r!
  • Samsung's and Huawei's will most definitely.
  • Yes.
  • Agree and hopefully by Christmas time but if I know Microsoft maybe late next year in order to add in an extended waiting period which of course is not necessary...
  • Meh - if it's not capable of being a phone, I don't see the need. Last thing I want is to have to carry around this device and a phone, plus the chargers and cables for both. If it can't be a phone, I don't see the need. My expectation is that this will be capable of being a phone, if you want it to be. Kind of a gateway device back into the ecosystem while they get their store in order.
  • People questioned why one would want to need a PDA, and hey look where we are now. Just because YOU don't see the need, doesn't mean large groups of other people share the sentiment. I don't care one bit about GoT but that's just me, get my point?
  • Where are we now with PDAs? You lost me. Plus I remember when PDAs came out. I had one for work. I don't recall anyone questioning the need for a PDA. Most thought it was an interesting gadget.
  • I did.
  • I look forward to how Dell's option stacks up to Microsoft's. I'm currently using Dells version of the surface pro and it has some nice additional features. So long as these devices do telephony as well I'll be picking one up day 1.
  • The article doesn't state why they think this device will be running Windows... How do we know this won't run Android?
  • Same here at my corporation. the Dell replacement of the Surface Pro is costing almost 1k less and it looks very similar, same responsiveness and speed I even think it's produced in the same factory
  • 2019 Is going to be interesting with Windows on arm devices using the Snapdragon 850/855 SOCs, which should be 50% faster than the 835.
  • What if... Thinking back to what we saw with the recently announced Surface Hub 2 and applying that to a mobile device. The big features of Surface Hub 2 was being able to have multiple Surface Hub 2's combine into one cohesive workspace. How would that model apply to a mobile device? What we are seeing now in the patent filings is one device with two screens.
    What if it is not just one mobile with two screens but two independent devices that link together?
    What if the other independent device is your Android phone running a special app?
    How many of these types of devices would it make sense to link together?
    Hmmmm….
  • Microsoft at Build did introduce an application called My Phone that will mirror the contents of your smartphone on a Windows device. You can reply to notifications and text messages thur this app.
  • Good stuff. That makes since if you can't access your phone since it would be in "PC mode"
  • What if this mythical device gets attraction in the corporate / prosumer space. In that case I would not be surprised that the Release III of that foldable future device will have 4 screens, if the processing power is there and they manage to reduce battery consumption the sky truly is the limit...
  • So, the rumor is thinning to finally reveal reality.
  • Instead of foldable, it is more "mobile Surface hub2" ! Instead of Intel, it uses Snap850. Imagine, user can buy one or two individual unit(s). These two units can click together on demand as two tiles just like surface hub2, but instead huge and standing, they are on your hand or hands. Way to go! Microsoft!
  • You just described the Attache, snap two or three screens together with magnets. The Dell J****s is possibly along this line also, but wonder if they are two identical devices which would duplicate the chipset and camera. Would make more sense to have one master device and one or more slave devices that are basically a screen and battery... click 3 or 4 of them together for a widescreen.
  • Microsoft's Vision 2020 - released in 2009 (see 2min21sec https://youtu.be/ozLaklIFWUI) It takes 10 years to build the user community to accept tiles and integrate inking..., trials and errors (Win8, WinRT, W10M...) to get to modular WinCoreOS and CShell and always connected PC... All pieces are now in place, we need more concerted efforts from users to adopt devices running WinOnARM (Snap850 or 1000) and push this 10 years old future vision through the last few miles.
  • To be honest what i really want is something like the Lenovo yoga book, running on ARM, with a USB-C port and i'd be happy as a pig in... An OLED screen thrown into the mix would be an added bonus but not a must
  • Surface's mission is about "creating categories" I suspect that Dell isn't going to be the only OEM working on one of these.
  • First, it is creating category. After seeing what Surface Hub2 can do with the modular WinCoreOS, Surface now becomes democratizing categories
  • I would be awfully surprised if HP didn't have a similar device up its sleeves.
  • Needs to be a phone FIRST... with all the features any premium phone has... that just so happens to fold into a small tablet. At 90 degrees should have a haptic keyboard or haptic game controller on one side and 6 inch wide screen on the other. Premium finish. $999. Anything short of that isn't worth that much of a paycheck.
  • I can already say now that it will bring little new to the table. I have a Alienware m14x i7 2860QM, 16GB ram plus a decen Nvidea GPU in it running Win 10 Pro so why would I need a fold able tablet with win 10 on? For anything less my Lumia 950 XL and Samsung Galaxy S8 are sufficient. Why would I need a tablet that can fold? Seriously? What I needed to hear this year was that Microsoft wanted to keep supporting Windows 10 mobile and not shut it down little by little. Or that they would ship a new phone with Windows 10 on. Actually I needed to hear that last year and not this year....
  • Hmm so far Windows 10 on ARMS software paired with the qualcomm snapdragon
    835 ARM CPU has been reported to be not so good because of slow response times
    users got trying to get their ARM devices to do things. The coming Snapdragon 850
    & 1000 are supposed to be much faster CPU chips. So it's wise for Dell to wait for
    better faster ARM's CPU's to come out before it takes the Plunge to make
    a 2 screen hybrid Mini PC Tablet
