I have connected my phone via USB C, but the agent does not run on my phone. How can I fix this?

Last updated: September 27, 2025

If you've connected your phone to your computer via USB-C but Caesr isn't able to control your phone, the solution depends on your phone's operating system. Here's what you need to know:

Android Phone Setup

For Android phones, Caesr requires ADB (Android Debug Bridge) to communicate with your device. Follow these steps to set it up properly:

Android Guide

iOS Setup

Connecting iOS devices to Caesr requires a customized installation process due to the unique security and operating system requirements of Apple's ecosystem.

  • Custom Installation Required: Unlike Android, setting up an iPhone or iPad to work with Caesr involves a specific, non-standard installation. Specifically, you need a hardware device for keyboard and mouse simulation such as a KVM switch (https://en.wikipedia.org/wiki/KVM_switch)

  • Contact Support for Assistance: To ensure a successful and secure connection, you need to reach out directly to the Caesr support team.

Troubleshooting Common Issues

ADB Connection Problems:

  • "Device not found": Ensure USB debugging is enabled and you've authorized the computer

  • "Unauthorized device": Disconnect and reconnect your phone, then approve the USB debugging prompt

  • "ADB not recognized": Make sure ADB is properly installed and in your system PATH

Phone Not Responding:

  1. Check USB cable - Use a high-quality USB-C cable that supports data transfer

  2. Try different USB ports - Some ports may be charge-only

  3. Restart ADB: Run adb kill-server then adb start-server

  4. Restart your phone and reconnect

Still Having Issues?

If you're still experiencing problems:

  1. Verify your setup:

    • Android phone in Developer Mode ✓

    • USB debugging enabled ✓

    • ADB installed and working ✓

    • Device authorized ✓

  2. Check compatibility:

    • Ensure your Android version is supported

    • Some heavily customized Android ROMs may have compatibility issues

  3. Contact support with:

    • Your Android version and phone model

    • Computer operating system

    • Output of adb devices command

    • Any error messages you're seeing

Important Notes

  • Security reminder: Only enable Developer Mode and USB debugging when needed, and disable them when not using Caesr

  • Cable quality matters: Poor quality USB-C cables may not support the data connection required for ADB

  • Wireless ADB: Advanced users can set up wireless ADB, but USB connection is recommended for stability

Once properly configured, your Android phone will work seamlessly with Caesr, allowing the agent to interact with apps, navigate interfaces, and perform tasks on your mobile device.
