Our summary

This project provides instructions and software for letting an AI assistant control a real Android phone. People use this to automate repetitive mobile tasks. It uses Jev, an AI tool that chooses from options rather than writing an answer.

The software looks at the phone screen and asks the AI tool to pick an action, like tapping. It records the chosen action immediately. If the connection fails, it will not try the same action again. This prevents the software from accidentally clicking a button twice.

This guide is useful for people testing automated mobile software. You need private access codes to use the required services. The AI claiming a task is finished is not proof of success. You must always check the actual phone to see if the changes happened.

Key takeaways

Always check the starting state of the phone before timing how long a task takes.
Record an action immediately so you have proof it happened even if the screen freezes.
Never let the software repeat an action if it is unsure if the first attempt worked.
