OpenClaw on Android: Complete Mobile Setup Guide (2026)

Your phone is probably the most powerful computer you carry around, so running OpenClaw on Android seems like an obvious move. And it works. Sort of. There are three distinct approaches, each with different trade-offs, and one of them will bite you if you don't know about Android's Phantom Process Killer.

The Official Companion App

The OpenClaw companion app (v2026.2.24) turns your phone into a hardware node. Camera, microphone, sensors. It feeds that data to your gateway running elsewhere.

Key thing: the companion app does not run a gateway. It's a peripheral. You still need a server handling the actual AI gateway.

Termux + proot-distro (Full Gateway On-Device)

The "I want everything on my phone" approach. Install Termux, use proot-distro to spin up Ubuntu 24.04, then run the full OpenClaw gateway on-device.

Expect 700MB to 1GB of overhead from the proot layer alone, plus a 20 to 30 minute setup process. OpenClaw pulls in node-llama-cpp at 752MB. If you're connecting to cloud LLMs through API keys, you don't need that local inference engine. Skip it.

Termux + Bionic Bypass (Lightweight)

Skips proot entirely. About 200MB overhead and a 3 to 10 minute setup. Runs Node.js directly on Android's Bionic libc with compatibility patches. Start here if you want lightweight.

The Phantom Process Killer Problem

Since Android 12, the OS aggressively kills background processes without visible foreground notifications. Your OpenClaw gateway dies while you're checking Instagram. Messages pile up. Contacts get silence.

You can disable it via ADB developer settings, but it resets after every reboot on some devices.

When Your Phone Isn't the Right Server

For a production setup where your AI assistant needs to be reachable around the clock, your phone is probably the wrong choice. It sleeps, disconnects from WiFi, the battery dies at 3 PM.
