Agentic Nexus is an open-source Android agent that lets you plug your own LLM into the phone’s system voice assistant and give it real device control (skills, shell/SSH, Shizuku, Root). It’s in beta, actively developed, and releases and docs are on the project’s GitHub.
This post explains what Agentic Nexus is, what it can do, what you need, how to get it, and how to set it up safely.

What is Agentic Nexus
Agentic Nexus (also called Nexus) is an Android app and agent runtime that replaces or augments your phone’s system voice assistant with a user‑configurable AI agent. It routes voice requests to your chosen model and can call tools, run skills, and execute terminal commands. Core idea: let your model orchestrate real tasks on the device.
Features of Agentic Nexus
- Model plug‑in: Use OpenAI, Anthropic, Google, DeepSeek, or compatible endpoints with your own API key.
- Skills system: Reusable task descriptions that the agent can call.
- Takeover rules: Decide which voice queries Nexus handles and which go to the system assistant.
- Terminal access: Three privilege tiers — normal app, Shizuku, Root — plus SSH to Termux or remote machines.
- Conversation history and memory: Persisted context and chat history.
Requirements
- Android phone (features vary by vendor and model).
- Model API key for the LLM you want to use (Nexus does not include model accounts).
- Optional: Root and LSPosed for full system assistant takeover on supported vendors (OPPO/OnePlus/Realme Breeno, Xiaomi XiaoAi).
Download
Get the latest release or source from the project GitHub Releases page. Use the release assets for APKs or follow the build‑from‑source instructions in the README.
Install
- Download APK from Releases or build from source.
- Enable install from unknown sources if sideloading.
- Grant permissions the app requests.
- If you need system takeover, follow vendor‑specific Root + LSPosed steps described in the README.
How to Use

- Configure Takeover Rules to choose when Nexus should handle voice queries.
- Add or enable Skills and tools (MCP integrations like Notion, GitHub, HomeKit).
- For terminal tasks, connect Shizuku, Root, or SSH as needed.

Troubleshoot
- Takeover not working: Check device model, assistant version, and Root/LSPosed setup.
- Model errors: Verify API key and endpoint settings.
- Permissions: Reopen app settings and re‑grant required permissions.
FAQs
No – Nexus works without Root but full system takeover needs Root + LSPosed on supported devices.
