  • Booting Windows 10 18362/18363 will lead to "static screen" effects on the right display, much like driver releases from last year did on any version of Windows. A fix is being worked on for the next release.

  • The TPM driver is not working for Windows 10 18362/18363. A fix is being worked on for the next release.

  • The Posture driver is not working for Windows 10 18362/18363. A fix is being worked on for the next release.

  • Enhanced auto rotation is not working for Windows 10 18362/18363. A fix is being worked on for the next release.

  • Brightness control is glitchy on both displays.

  • On device speakers are not functional.

  • Dongles are not detected correctly when plugged into the USB Type-C port.

  • Updating drivers may lead to weird configurations if done on old driver releases.

  • MAC addresses do not reflect the real addresses asigned to the device.

  • BitLocker drive encryption is not available.

  • USB dongles that are not externally powered may not currently work.

  • USB-C Billboard devices will not currently work.

  • External Display Stream support will not currently work.

  • Additional information provided by the posture sensor is currently not available for public consumption. This includes peek events.

  • Digitizers will not react to the device being folded over.

  • Displays will not react to the device being folded over most of the time.

  • Physical device data is incorrect.

  • Digitizers aren't calibrated correctly.

  • Flipping the device is not smooth.

  • Users upgrading from releases older than the January ones may want to clean install again.

  • Booting Windows 10 18362/18363 with Secure Boot enabled is not currently supported and will result in a broken installation.

  • In some cases, booting the UEFI image may lead to "static screen" effects on the left display. Please do not force reboot the device as it may interrupt the installation process, if ongoing, and instead please wait a few minutes.

  • Windows Recovery environment lacks drivers unless Windows has performed a Feature Update at least once.

  • sRGB is not available currently, and displays will not react to ICC profiles being applied.

Accessing Foldable Sensors from your applications

In order to currently access the sensor data given by the foldable sensors, you need to use the following apis:

  • Windows.Devices.Sensors.HingeAngleSensor*
  • Windows.Internal.Devices.Sensors.FlipSensor* (2)
  • Windows.Internal.System.TwoPanelHingePostureDevice* (2)

(2): These apis require the use of an externally sourced winmd available from https://github.com/ADeltaX/InternalWinMD/blob/master/%23winmd/Windows.Internal.Devices.Sensors.winmd

In the future, further apis will be functional (specifically under the Windows.System.Preview namespace). Consider this an early "thing".

The following API may be used to determine if your app is used on a dual screen device: https://docs.microsoft.com/en-us/uwp/api/windows.ui.windowmanagement.windowingenvironment.getdisplayregions?view=winrt-22621

The following API may be used to determine on which display region your app is currently being shown: https://docs.microsoft.com/en-us/uwp/api/windows.ui.windowmanagement.appwindow.getdisplayregions?view=winrt-22621

The following API may be used to move your application to the other display: https://docs.microsoft.com/en-us/uwp/api/windows.ui.windowmanagement.appwindow.requestmoverelativetodisplayregion?view=winrt-22621

THe following API may be used to move your application to a specific display: https://docs.microsoft.com/en-us/uwp/api/windows.ui.windowmanagement.appwindow.requestmovetodisplayregion?view=winrt-22621

The following API may be used for spanning purposes: https://docs.microsoft.com/en-us/uwp/api/windows.ui.windowmanagement.appwindow.requestsize?view=winrt-22621

The Windowing Environment for Windows Desktop editions (outside of tablet mode) is Overlapped. Tiled is used for Tablet Mode and Windows Core OS's ModernPC.

Dual Boot Information

Important!: The Dual Boot images currently target the following Android OTA update versions from Microsoft. These images can only be used on a phone that had as latest the following OTA versions from microsoft even if you are currently running a custom android system image. Using these images will work with a custom Android System Image but the device bootloader and firmware must be from the same Microsoft OTA version as shipped from the stock Microsoft Android Updates!

Device Name Device Variant Dual Boot Compatible with the following firmware/bootloader version only
Surface Duo United States of America (GEN) 2022.902.48 (Latest OTA for Surface Duo (1st Gen) devices)
Surface Duo United States of America (AT&T) 2022.902.48 (Latest OTA for Surface Duo (1st Gen) devices)
Surface Duo Europe (EEA) 2022.902.48 (Latest OTA for Surface Duo (1st Gen) devices)
Surface Duo 2 United States of America (mmWave) 2023.501.541 (Latest OTA for Surface Duo 2 devices)
Surface Duo 2 Europe (5G NR) 2023.501.541 (Latest OTA for Surface Duo 2 devices)

Flashing these images on any other version may brick your phone or render touch unusable! Make backups of your original boot partitions and ALWAYS test before flashing permanently using "fastboot boot image.img"!.

If you do not currently run above firmware versions, please also follow https://github.com/WOA-Project/SurfaceDuo-Guides/blob/main/Install/DualBoot.md.

For more information on dual boot, manual steps on how to craft such image file, and how to flash it, and use it, please visit https://github.com/WOA-Project/SurfaceDuo-Guides/blob/main/Install/DualBoot.md.

We do not recommend inexperienced users without advanced knowledge of IT/Command prompts to do this ever. You may find it very hard and mess up your device easily if you do it wrong. Also important to note Android OTAs will not work anymore with a custom boot.img flashed onto the device and you will need to reflash your original backup for them to work or else, you'll be forced to recover with an OTA zip package from https://aka.ms/sri if one is even available for your current version or higher.

Some examples about what above warning means for you when running custom operating systems on your surface duo and if you are willing to run dual boot images

To clarify above bullet point

If for example you flashed the Pixel Experience Android 13 Android System Image on your Surface Duo, and previously you were running Microsoft Stock Android OTA version 2022.123.45, your device firmware and bootloader are still version 2022.123.45 and will not be compatible with these images targeting 2022.902.48

In another example, you flashed the Pixel Experience Android 13 Android System Image on your Surface Duo, and previously you were running Microsoft Stock Android OTA version 2022.902.48, your device firmware and bootloader are still version 2022.902.48 and you are compatible with these images.

You are currently running stock microsoft android version 2022.902.48; you are compatible

You are currently not running stock microsoft android version 2022.902.48; you are not compatible

Hey wow, that's a lot of UEFI images right here! Which one do I even download?

  • FastBoot -> Image intended to be used with fastboot boot uefi.img to directly boot into the UEFI this way via your computer, use this one if you're following the installation guides right now
  • Dual Boot -> Image intended to be flashed onto boot after checking compatibility with above table to make sure you meet the usability criteria and your device will work fine
  • FD -> File needed to make your own custom dual boot images in case you do not meet the compatibility table, using the guide to do so (https://github.com/WOA-Project/SurfaceDuo-Guides/blob/main/Install/DualBoot.md)

Use the files without SecureBoot Disabled in their filenames if and only if:

  • I am booting a version of Windows higher than build 18363 (the latest Windows 10 feature update, Windows 11, Windows 11 Version 22H2 etc..)

Only use the files with SecureBoot Disabled in their filenames if and only if:

  • I am booting Windows 10 build 18363 or lower on my device (Please also turn on testsigning in BCD in order to boot)
  • I am booting Windows 10X on my device
  • I am booting a linux distribution
