Repository navigation
Run Android Auto and Samsung DeX directly on the phone's own display.
Download the APK, not the source zip
On this page, open Assets and take prism-1.0.6.apk.
Do not download Source code (zip) or Source code (tar.gz). GitHub attaches those to every release; they are the repository snapshot, not an installer.
Do not use the green Code → Download ZIP button on the repo either.
Official repo: https://github.com/hongducdev/prism — owner must be hongducdev, name must be prism. Always use the release marked Latest.
What's new in 1.0.6
- Android Auto self-mode — run Android Auto directly inside Prism on the phone, powered by a bundled head-unit receiver (Open Head Unit). AA 17.4+ needs Developer mode and Head Unit Server; older versions start through local self-mode automatically.
- Samsung DeX on device — switch the built-in display to Samsung DeX without a monitor, using a Vector hook into Samsung's desktop-mode service.
Requirements
- Samsung, One UI 7 or 8
- Android 12+
- Vector or LSPosed for hooks
- Shizuku or root for the privileged tools
Enable Prism in Vector/LSPosed and tick Prism itself in the module scope so the app can see that the module is active. On-device DeX requires Prism enabled for Android/System Framework.
