duo-de ^{[surface-duo desktop experience]}

This is a GSI variant rom build targetted for Microsoft Surface Duo with the intention of using the Surface Duo as a desktop environment using experimental floating window features. This build combines gapps/vanila variants of the GSI rom from ponces with desktop mode enabled + various tweaks to make it nice and smooth with the help of thain tweaks. All credits go to respective developers. Desktop mode can be disabled from the home settings, if required. The latest version is stable and secure for daily usage.

Posture Engine

With the posture processor engine, both duo1 and duo2 react to various postures. Specifically, the touch configurations and display settings will toggle between left-screen phone mode, right-screen phone mode, and tablet mode based on the hinge position. The hinge gaps can be enabled/disabled through the treble app.

Flashing steps

Try this at your own risk and proceed with caution!

Following are the steps to flash this image to your surface duo.

1. Download the release.

wget https://github.com/Archfx/duo-de/releases/download/<<version>>/aosp-arm64-ab-gapps-14.0-<<version>>.img.xz
tar -xf aosp-arm64-ab-gapps-14.0-<<version>>.img.xz
# or
gunzip aosp-arm64-ab-gapps-14.0-<<version>>.img.xz

2. If you are migrating from Android 12L (stock) follow this step. You need to unlock the bootloader before proceeding. Please pay attention to commands, do not copy and execute the commands blindly.

adb reboot fastboot
fastboot delete-logical-partition system_ext
fastboot delete-logical-partition product

#get the current slot
fastboot getvar current-slot
# if current slot is a, delete the system_b
fastboot delete-logical-partition system_b
# if current slot is b, delete the system_a
fastboot delete-logical-partition system_a

fastboot flash system aosp-arm64-ab-gapps-14.0-<<version>>.img
fastboot reboot 

3. Migrating from 13/14 pixel experience, follow the below steps

adb reboot fastboot
fastboot flash system aosp-arm64-ab-gapps-14.0-<<version>>.img
fastboot reboot 

4. Perform a manual reboot once the device is booted to the home screen so that first-time configurations are applied.
5. Once you flash a duo-de version using the above steps, subsequent updates will be received using OTA. You can check updates using settings -> system -> system updates.
