Jev-PhoneControl

Android control prototype with three agents: vision model, text-only supervisor, and Jev choosing actions and checking completion.

Overview

Jev-PhoneControl is a source-available Android control prototype (v0.0.1, Chinese documentation) with a local web console and API. A vision agent sees only screenshots and outputs an English description plus candidate actions with normalised coordinates. A text-only supervisor agent sees the task, the vision report and history, proposes the next goal and judges completion evidence. A Jev agent uses Choice to select among candidate actions and Noul to cross-check completion evidence.

An executor performs taps, long presses, swipes, back and text input through ADB and re-screenshots after each step. The model cannot run arbitrary commands, and sensitive actions such as payment, sending or deleting require explicit confirmation in the API, after which the target is re-verified. Jev calls retry on transient errors with backoff. The licence is PolyForm Noncommercial, so commercial use requires permission.

What the decision model decides

TypeQuestionAnswers
ChoiceWhich candidate action should be executed next?—
Yes / noIs there evidence the task is complete?yes · no

How it works

  1. Screenshot the phone and get candidate actions from the vision model
  2. The supervisor proposes the next goal
  3. Jev chooses a candidate action
  4. Sensitive actions wait for user confirmation
  5. ADB executes and a new screenshot is taken

Strengths

  • Clear separation of vision, planning and decision roles
  • Sensitive actions require confirmation
  • No arbitrary command execution

Caveats

  • Non-commercial licence
  • Needs three model providers including TypeSafe
  • Early prototype tested mainly on Windows

Getting started

pip install -e . in a venv, set CONTROLPHONE_ADMIN_TOKEN, run uvicorn controlphone.api:create_app --factory --port 8000, then configure models at http://127.0.0.1:8000/

Frequently asked questions

What does Jev decide?

Which candidate action to take and whether completion evidence holds.

Can I use it commercially?

Not without permission; it is under PolyForm Noncommercial 1.0.0.

How are risky actions handled?

Payments, sending and deleting wait for explicit confirmation and re-verification.
