* Add VITURE glasses support: hardware control, 3D, head tracking Glasses get their own controller over the MCU (permission, 120 Hz default, brightness, volume, sunblock, 2D/3D) and the game moves onto them when plugged in. The IMU drives Cardboard head tracking and the SteamVR driver. 3D falls back to one eye's view on phones that can't send the 3840x1080 signal. Options open from a glasses button in game and on the Steam page. * Drop the glasses settings like Steam's: Play-style button, Settings lip, tabs * Hang the glasses Settings lip over the top of the button * Space glasses MCU commands so the IMU rate sticks, fit fixed resolutions to the glasses * Keep Steam alive with SteamVR registered, run SteamVR at the glasses' rate, keep the glasses lip on top * Fit VR games on the glasses: full view, seated origin at the head, pad hands reach with the d-pad * Let the pad hands reach a metre out so buttons with deep colliders press * Show every VR frame in order at 120 fps: wait for SteamVR's GPU work, present only finished copies, skip the grace on idle shared counters * Glasses: SteamVR starts and stops with them, closer view with a field of view setting, Recenter on the pad * Glasses: SteamVR field of view defaults to 90° * VR pad hands: sticks move and aim the hands, left stick click switches the sticks to the game, d-pad pulls a held hand * Glasses: Play SteamVR beside the glasses button instead of starting SteamVR with them, pad hands drawn as Index controllers and off while other VR controllers are connected, glasses sheet tabs sized like Steam's * Track glasses mode, refresh-aware glasses window, align Play SteamVR with Play Steam * Fix 3D on the glasses: full-res SteamVR presenter, revert VR 3D at session end, coalesce vsync ticks, no session restart after end * Address review: glasses output after installs and session end, VR revert retry, display fallback, presenter swapchain retry, agent hex checks, drawer bumpers, glasses translations, docs * Harden VITURE stereo negotiation and output refresh tracking * Localize stereo recovery feedback and record Astra reconnect tests * Improve test failure diagnostics and refresh Astra firmware findings * Handle VITURE docks separately and reject truncated USB frames * Glasses: remember a 3D fallback per model, docks as display only, VR timing fixes - A 3D attempt that ends at the 640x480 fallback is remembered for that glasses model, so Play SteamVR no longer blacks out the glasses after every restart; Retry clears it and "3D for VR games" stays reachable - A VITURE Mobile Dock on its own no longer counts as glasses; through a dock Play SteamVR is hidden and the sheet shows the output and why there is no control - HDR is probed on the glasses when the session starts there - Glasses frames with a mismatched checksum are marked in the status frame log - SteamVR layer and driver vblank counters stay monotonic across refresh changes; one-eye render scale applies from activation and on mono/3D switches - Compositor binds announce the refresh clients were last told; the presenter retries a failed first swapchain - Dead strings and helpers removed; docs updated * Glasses: drop USB frames with a bad checksum * Glasses: count frames dropped for a bad checksum * Feat/viture xr (#907) * Add RayNeo Air and GT support to the XR glasses pipeline * Add RayNeo Air and GT support to the XR glasses pipeline * Checkpoint glasses tracking, calibration, and SteamVR launch integration * Checkpoint glasses tracking, calibration, and SteamVR launch integration * Add XREAL 1S support and correct GT and Pro 2 tracking * Add XREAL 1S support and correct GT and Pro 2 tracking * Fix mirrored glasses tracking and recover SteamVR after device loss * Fix mirrored glasses tracking and recover SteamVR after device loss * Document confirmed XREAL 1S brightness control * Document confirmed XREAL 1S brightness control * Fix SteamVR glasses defaults and rendering controls * Fix SteamVR glasses defaults and rendering controls * chore: keep only the 3 newest session log folders (#852) * chore: add agent comment rules (#748) Co-authored-by: Kurt Himebauch <136133082+xXJSONDeruloXx@users.noreply.github.com> * Fix SteamVR polling, VITURE checksums, and fence tracking Keep manual SteamVR launches polled, discard corrupt VITURE packets, and retire Vulkan fences out of order without blocking submissions at a fixed capacity.

Include the pinned hand model and calibration board. Keep live guest and SDK files outside Android's evictable cache. Filter the Adreno 840 sysmem override in the shared SteamVR helper, serialize timeline mirroring, retain invalid optical controllers without event floods, and prevent an unprivileged scheduling fallback from lowering compositor RTTIME. Validation: latest APK build and runtime freshness checks pass; 247 affected glasses/calibration tests pass. Native VR, helper, and packaging regressions pass. Two earlier phone library launches sustained 60 fps for 308 and 188 seconds without recovery or restart. The newer calibration APK is installed and checksum-verified; calibrated-hand and sustained gameplay acceptance remain pending. One existing Android test requires Windows symlink privileges. * Headsets: settings badge on Play SteamVR instead of a top-right button, both shown only once connected * Hand tracking: camera-tracked Joy-Cons and bare hands in SteamVR, drawn as white gloves - Joy-Con movement from the accelerometer (report reordering, per-Joy-Con calibration, zero-velocity updates) - MediaPipe pose and hand landmarks from the device camera, placement check, per-hand Kalman filter with the Joy-Con - No controller connected: bare camera hands with Quest-style gestures, 1€ filtered, rendered as a white glove model built from a distance field - SteamVR safe mode cleared before each start so one crash no longer blocks the driver * Improve Luma Ultra tracking and isolate device-specific controls Refine stereo hand and Joy-Con tracking, gesture release, calibration, recovery UI, diagnostics, display modes, and compositor handling. Keep Ultra controls and input routing behind a live SDK-confirmed Carina connection; clear retained spatial mode when other glasses connect. Add optional UVC transport with pinned dependencies and packaged notices. Validation: 456 Android tests, ARM64 VR build and native regressions, 47 tooling tests, SDK/UVC-enabled and disabled builds, and 150 packaged runtime checksums. Two shader compilation tests skipped because the compiler is unavailable. Hardware interaction gates remain experimental. * Delay Luma Ultra 6DoF until SteamVR settles Suspend spatial SDK startup while SteamVR launches, then restore it two seconds after RUNNING is confirmed. Preserve saved tracking preferences and automatically recenter same-device restoration, including cancellation and early stop. Discard superseded launch requests and status replies after session teardown. Validation: 128 focused JVM tests passed on the isolated commit snapshot; 129 passed with the current local hand-tracking work. Debug build and runtime checks passed, and the reviewed APK was installed and hash-verified on the phone. * Clarify glasses and phone camera tracking options Separate Luma Ultra camera controls from phone-camera tracking so the two hand-tracking switches have clear sources. Label bare-hand controllers and Joy-Con position tracking explicitly, explain physical Joy-Con inputs and camera priority, and update the camera prompt and calibration guidance. Use fresh phone section and toggle labels so existing translations do not hide the distinction. Preserve tracking behavior and saved preferences. Validation: 39 existing UI tests, debug build, and packaged runtime verification passed. Reviewed changes and installed the APK on the connected phone. * Fix tracking handoff and shared runtime regressions Release spatial ownership and controller overrides when output returns to the phone. Preserve USB-loss recovery, keep Vulkan submissions asynchronous, clean persistent guest scratch on runtime removal, and clarify the 6DoF head-tracking control. * Apply smart-glasses virtual screens across DroidDeck menus * Finalize Luma hand baseline and document smart-glasses support Keep raw grayscale-to-RGB Full hand inference, wrist-only Joy-Con reconstruction, bounded visual holds, and the dead-zone rollback. Retain opt-in steady aim, recenter controls, reproducible Lite models, and the JPEG-padding fix. Remove unsuccessful benchmark-only and USB transport experiments. Document the cross-brand 3DoF matrix, Luma Ultra 6DoF, SDK requirements, and app-wide screen behavior. * Fix executable permission for SteamVR launcher * Address hand tracking and VR review findings * Bound stereo recovery test image comparison memory * Localize smart-glasses setup and tracking diagnostics Move calibration controls, status messages, validation errors, distance labels, and printed-board instructions into Android string resources. Add and update machine-assisted translations in all 32 supported non-English locale catalogs, with corrections for recentering, hand tracking, product names, and measurements. Keep print instructions within the page using text layout that supports wrapping and right-to-left text. Correct the Lite model toggle description to reflect its Lite palm detector and Lite landmark model. Add locale coverage, format-argument, line-break, and measurement checks, plus French and Arabic calibration UI tests. Preserve tracking calculations and the shared runtime storage behavior. Validation: Android resource and Kotlin compilation; 3 localization checks; 68 focused tests; 1,597 JVM tests at a 512 MB heap; French and Arabic UI renders. * Correct smart-glasses translations from PR review Fix the 42 localization findings covering hand and head terminology, disabled states, calibration dimensions, camera visibility, capture rejection, and menu references. Correct the repeated capture-error ambiguity in related locales and clarify its English source. Keep Romanian setup instructions consistent with the existing informal voice. Extend localization measurement validation to distance hints and retry guidance. Verify the recovery screen's palette-dependent text color with one row-sized pixel buffer and guaranteed bitmap cleanup.

DroidDeck brings the SteamOS experience to Android: Valve's Steam client in Big Picture on your Adreno handheld, with Windows games through Valve's ARM64 Proton.
Note: DroidDeck does not have a stand-alone website. Do not click on any download links from websites claiming to be the DroidDeck team.
Requirements and install
Use Android 9 or newer on a supported Adreno device (730 or newer, or 8xx). Adreno 6xx is experimental: DirectX 11 uses DXVK 2 and may run, and DirectX 12 games can still crash. Mali, Xclipse, PowerVR, and Adreno 710 are unsupported. No root is required. Allow about 3 GB for the runtime and 1.1 GB more for the desktop and emulators. Install the APK from Releases, install the Linux runtime, then press Play and sign in. Steam downloads on first launch. Install Desktop & apps to use the desktop and emulators. The Store installs Linux apps and games from Flathub (ARM64 builds) with Flatpak; with additional options to install Appimages and set up scripts. Stores (Setup › Stores › "Show Stores in the rail") signs in to GOG, Epic Games and Amazon Games and downloads games into the Games storage. Epic keeps its direct API install path. Opening Epic Stores prepares Epic’s official Linux launcher preview. When installed, Epic games launched from DroidDeck use that client, and games installed in the client are imported into DroidDeck’s library and shortcuts. The x86-64 client runs through FEX on ARM and DroidDeck retains its Proton hooks; this preview and ARM setup are outside Epic’s listed Linux support. The cog on a store’s chip row sets its opening tab and download speed tier.
On Android 14 and newer, before Steam launches, you must turn on Disable child process restrictions in Developer options. If this option is not available in developer settings (Android 12 and 13 devices), first launch of Steam will present a "Fix it for me" button, which will help automate the setup process.
Smart glasses
Use Setup → Smart glasses for app-wide virtual-screen settings across DroidDeck menus, launchers, desktop sessions, and games. Supported VITURE, RayNeo, and XREAL connections provide 3DoF; Luma Ultra adds optional experimental 6DoF and stereo-assisted hand/Joy-Con tracking. Model support and SDK requirements differ: see the smart-glasses support matrix for supported devices, controls, setup, and limitations.
Community
Join the DroidDeck Discord for help, Preview builds, and device reports. Bug reports go in its #bug-reports forum; attach the zip from Share logs (Setup, or the session drawer) so the logs come with it.
Build
Run tools/build_local.sh with Docker, Java 17, the Android SDK/NDK, Rust through rustup, GitHub CLI, Python 3, and zstd installed. It prepares the same native libraries, pinned components and audio sinks as CI, then checks the APK's assets, JNI exports and dependencies. The APK is at app/build/outputs/apk/release/app-release.apk. Set DROIDDECK_PA13_SOURCE_DIR to an existing PulseAudio 13.0 source directory to skip downloading it. Set DROIDDECK_SIGNING_ENV to a signing environment file to install over a release build; relative keystore paths resolve beside that file. To install on an attached device, run tools/deploy_local.sh.
After preparation, ordinary ./gradlew :app:assembleRelease builds can reuse the verified inputs. If native sources, component pins or staged files change, packaging stops with instructions to rerun the helper. Generated audio stays under app/build/; the tracked base bundle is never modified. ./gradlew -PskipRust=true :app:testDebugUnitTest needs no native preparation. For an APK without store engines, use DROIDDECK_SKIP_RUST=1 tools/build_local.sh; it omits cached engine libraries too.
For the prepared Windows checkout, run ./tools/run_windows.ps1 (optionally with -Serial <adb-serial>), or select DroidDeck XR in Android Studio and run the app module on the connected phone. Machine-specific options live in the ignored local.properties: droiddeck.python selects a Python executable, droiddeck.skipRust=true omits the optional store download engines, and droiddeck.debugApplicationIdSuffix=.xr installs DroidDeck XR Dev alongside the signed release. The development app has its own runtime and Steam login. The local Java selection is in .gradle/config.properties.
python tools/prepare_windows_runtime.py restores this checkout's audited runtime inputs from the pinned CI APK, three locally rebuilt preload libraries, and the checksum-pinned Gamescope archive in build/windows-setup/. Start Docker Desktop's Linux engine first: preparation now rebuilds DroidDeck's ARM64 VR driver and Vulkan layer from current source and runs their native regression tests. The compiler image is built automatically on first use. Vulkan headers come from the NDK beside --llvm-strip, or from an explicit --vk-include <NDK-sysroot-include> directory.
To reuse that build, pass --rebuilt-vr build/windows-setup/vr. Preparation verifies its vr-build.json against the current Git revision, source files, Vulkan headers, output checksums, and ARM64 architecture; missing or stale builds fail instead of falling back to the donor's VR libraries. The script checks the actual donor CI merge tree, still rejects unrelated unaudited runtime changes, and records component provenance in app/build/windows-runtime-provenance.json. Preserve these ignored preparation files when rebuilding locally; clean removes the prepared assets and their verification manifest.
Run the helper and preload regression suite with bash tools/test_local.sh. On macOS it runs in Linux through Docker, matching the helpers' runtime and CI instead of compiling Linux preloads against macOS headers.
Limits
Compatibility and performance vary by device; hardware validation is limited. Desktop compositing uses software rendering. Firefox sandboxing is reduced under proot. Logs are kept app-private (files/logs/, the last 30 sessions); Share logs packs the newest session, with the stores and tool logs, into one scrubbed zip.
Credits and licence
GPL-3.0. Runtime, shim, input, and controller work build on WinNative and Bannerlator (maxjivi05). Epic Games and GOG support build on Phobos’s adaptation of Legendary and gogdl, respectively. LSFG frame generation is from the work of Camille LaVey and the Eden emulator project, following lsfg-vk, ported to WinNative and DroidDeck by @maxjivi05; it needs your own copy of Lossless Scaling and ships none of its shaders. x86 AppImages, and any whose own runtime cannot unpack them, are unpacked with uruntime by VHSgunzo (MIT), shipped unmodified with its licence. mmap ring-buffer controller input was developed by ribbit384 (WinNative #345). See LICENSE. Steam and Proton belong to Valve Corporation; this project is not affiliated with Valve.
XR glasses support builds on WinNative's VITURE glasses work. VITURE protocol details were checked against XRLinuxDriver by @wheaney, including the VITURE protocol header it ships, ar-drivers-rs by @badicsalex and the go-macos/iokit VITURE package; the optional VITURE SDK belongs to VITURE and is not included. RayNeo support adapts @informalTechCode's RayNeo-Air-Series-3DoF-Scaffold (Apache-2.0) and references @verncat's RayNeo-Air-3S-Pro-OpenVR (MIT) and Monado (BSL-1.0); see docs/third-party/rayneo. XREAL 1S support references XRLinuxDriver and xrealOneDeviceKit by @wheaney, xreal_one_driver by @rohitsangwan01 (MIT) and xr-tools by @0xcaff. The REDMAGIC glasses-display findings draw on @mekhontsev's MagicDesk investigation and @Coding-BR's decompiled Nubia kernel. VITURE, RayNeo, XREAL and REDMAGIC are trademarks of their owners; this project is not affiliated with them.
Joy-Con VR controllers port the arm model of Google's Google VR SDK for Unity (Apache-2.0), adapt the hand skeleton of Valve's OpenVR handskeletonsimulation sample (BSD-3-Clause), which follows Moshi Turner's hand simulation in Monado, and use the Index controller offsets from Monado's vive_poses.c (BSL-1.0). Joy-Con behaviour was researched in Linux's hid-nintendo driver by Daniel J. Ogorchock, @dekuNukem's Nintendo_Switch_Reverse_Engineering, SDL and the Android Open Source Project, and checked against ALVR, OpenComposite, PSMoveSteamVRBridge, @F8LEFT's JoyConVr, @krnelpan1c's Daydream-Controller-SteamVR, @yoyobuae's joyconvr, Moonlight and Dolphin; see docs/third-party/joycon.

Camera hand tracking runs Google's MediaPipe Tasks Vision library with its Pose Landmarker (Lite) model, BlazePose GHUM 3D, and its Hand Landmarker model (all Apache-2.0), on frames from AndroidX CameraX (Apache-2.0); MediaPipe's usage reports are switched off. The design was checked against @F8LEFT's JoyConVr camera app (MIT), and the short Joy-Con movements follow the accelerometer mode of the Google VR SDK for Unity's arm model, Eric Foxlin's zero-velocity updates and Frosio, Pedersini and Borghese's accelerometer autocalibration, and the camera and Joy-Con are joined by a Kalman filter (R. E. Kalman, 1960). Bare camera hands take their gestures after ALVR's hand_gestures.rs (MIT) and Meta Quest's menu pinch, with distances checked on photos from the HaGRID gesture set (CC BY-SA 4.0, not included), fit the palm with Horn's quaternion method (1987) and smooth it with the 1€ filter (Casiez, Roussel and Vogel, 2012); the white glove model follows Valve's OpenVR render model reference and Index controller poses, is meshed with surface nets (Gibson, 1998; Mikola Lysenko) and blends and shades it with Inigo Quilez's smooth minimum and distance-field ambient occlusion, porting his polygon distance (MIT); see docs/third-party/handtracking.
