Microsoft introduces a Surface phone called Surface Duo

Surface Duo is the first Surface to fit in your pocket. Surface Duo brings together the best of Microsoft productivity experiences, Android apps and Surface hardware design into a single device you can take anywhere. And, yes, it makes phone calls. It has two paper-thin 5.6-inch screens that unfold to 8.3 inches, and just like Surface Neo, it can be used in a variety of modes to let you work the way youd like.

To support Surface Neo, we are introducing Windows 10X, an expression of Windows 10 designed for a new category of dual-screen PCs. With Surface Duo we are building upon Android to marry cutting edge hardware with familiar software and services. Were excited to work with developers and the industry to create the next wave of dual-screen computing and unlock a new era of mobile creativity.

The Surface Duo and Surface Neo will be coming in Holiday 2020.

Surface Duo SDK Preview is getting an update – Feb 20, 2020

Hello Dual Screen developers!

We are proud to be part of this growing community and excited to share with you the latest on the #SurfaceDuo SDK front in these devblogs.

Don’t forget to read our previous editions for additional Dev goodies, and let us know (feedback links below) on what else you would like us to cover.

For today’s blog on 02/20/2020, we are going to focus on the Surface Duo Emulator Image refresh (Yes, almost a palindrome, if you’re into numbers).

Summary of changes in the 02022020 update

We have spent the past few weeks with fixing some bugs with some great results. We have updated how we report the display size, modified the DisplayMask API to improve app compatibility, and fixed several bugs that our users have reported.

You can download the refresh image for Mac, Windows and Ubuntu using this link

In details:

Change #1: Changes to how size is reported to an App:

We have been busy setting up an App Compat lab where we test against the top apps from the Google Play Store.

We found some inconsistencies in how activity, window, and display metrics were returned to apps and games. We have made the changes to how size is reported so that the app gets sizes appropriate to the displays it is on. In the case of:

For apps on a single display, windows and display metrics will be related to a single display

For apps across both displays, window and display metrics will be in relation to both displays, including the display mask

Our Java and Kotlin samples have been updated to reflect this change.

Try it out on your app and let us know if you’ve seen any issues.

Change #2: Updates to DisplayMask API

Display Metrics based on apps window and DisplayMask API change to return hinge mask relative to apps window:

Display Mask has been updated to return a bounding rectangle relative to the display metrics based on the app context. When running in single screen the DisplayMask will now return an empty list it will not intersect with the window. When running in dual screen the display mask bounding rectangle shall identify the area under the hardware hinge in relation to the app window.

As consumer of this API apps run in one of the following scenarios:

App running in single screen mode: DisplayMask will be an empty list

App running in spanned mode: DisplayMask = hinge mask rectangle

Note: a service that created a view at any point will fall into one of the categories above

Change #3: Surface Duo Image Build Flavor is now a USER build and not USERDEBUG

This image refresh contains a USER build flavor which will result in less logging and faster image access within the emulator.

Note that the ADB commands will continue to work as usual without the need to enable Developer Options in settings.

Figure 1: The Surface Duo emulator image with Drag and Drop Sample

Behind the scenes on these changes:

If you’re interested in the behind the scenes on these changes, this section is for you.

Apps query their active window and active display information using a common class – android.view.Display.

The common behaviors and API’s within android.view.Display are:

Getting current App Windows metrics (getSize / getMetrics) which returns the display size available to the app adjusted for specific system décor (cut-outs, nav bar, etc.) and compatibility.

When called within an activity with an app window this returns the size available to the app with specific system décor subtracted.

When called within an activity without an app window this returns the full display size

Getting the current “real” display metrics (getRealSize / getRealMetrics) which returns the display size available to the active WindowManager adjusted by any rotation. “Real” in this context is at times Windows Manager may run in a smaller display than the actual full available display.

The Surface Duo Emulator Image supports these standard API’s that apps depend on, but the API’s will further define “real” display based on current posture and app context.

If you would like to read more “behind-the-scenes” content, please let us know on the Surface Duo feedback forum.

Microsoft Surface Duo Emulator definitions

The Surface Duo emulator image has two displays. The gap between both displays is 84 pixels. The entire virtual display is represented as 2784×1800.

Android abstracts pixel size and resolution into a display-independent pixel metric so apps can use a single metric across devices. This is calculated as:

dp = (width in pixels * 160) / screen density

[table][tr][td][/td] [td]Native resolution[/td] [td]Resolution in dp[/td] [/tr] [tr][td]Single Display[/td] [td]1350 x 1800[/td] [td]540 x 720[/td] [/tr] [tr][td]Dual Display + Mask[/td] [td]2784 x 1800[/td] [td]1114 x 720[/td] [/tr] [/table]

Per the Material Guidelines, this would be classified as:

[table][tr][td][/td] [td]dp[/td] [td]Classification[/td] [/tr] [tr][td]Single Portrait Width[/td] [td]540dp[/td] [td]large handset[/td] [/tr] [tr][td]Single & Dual Landscape Width[/td] [td]720dp[/td] [td]large handset[/td] [/tr] [/table]

Because the default behavior for any activity creating a window is to be launched on a single screen, the display metric return value to all non-windowed activities will also be updated to be the size of a single screen to reduce discrepancies in an app default launch behavior.

To keep within the bounds of a large handset, future Surface Duo devices would need to keep a single display within the bounds of:

Portrait Width of 400-599dp or 2.5” – 3.74” (Surface Duo Emulator is 3.375”)

Landscape width of 720-959dp or 4.5” – 5.99” (Surface Duo Emulator is 4.5”)

The minimum aspect ratio recommended for Android based phones is 4:3/3:4 (which is what Surface Duo is).

We’d love your feedback

We would love to hear from you about your experiences using the SDK and emulator.

Please reach out using our feedback forum and let us know how we can help you be more productive, ask questions, make suggestions, or upvote other suggestions.

Microsoft wants to launch Surface Duo sooner than holiday 2020

Holiday 2020 is when Microsoft said to expect the Surface Neo and Surface Duo, two new form-factor devices that Surface fans have been waiting for with bated breath. But what if I told you that one of those products was ahead of schedule, and may be available to buy much sooner than anticipated. This is what I've heard from multiple contacts over the last couple of months.

According to sources familiar with the matter, Microsoft is hoping to launch Surface Duo much earlier than originally announced. This is because both the hardware and software are pretty much done. Android 10 has been complete since August 2019, so Microsoft is currently focused on finalizing the top-level OS customizations and in-box app experiences specific to Surface Duo.

I'm told that Microsoft is hoping to have all the software done by early April, and that Surface Duo could start shipping in limited quantities in time for the summer if everything goes according to plan. I expect that this initial launch will be aimed primarily at developers and enthusiasts, with its availability announced in the spring alongside the Surface Go 2 and Surface Book 3...
