Shared emulators leak identity across jobs: one fingerprint, one IP, one process that dies when the laptop sleeps. Parallel agent work needs separation.

FoxPhone is a cloud phone platform: isolated Android devices with their own fingerprints and networks, Android 10–15 on ARM, driven from a browser. Agents can install apps and walk flows across a fleet; one-click sync helps when a human needs a master window. Pricing is usage-based with a free trial.

Start at FoxPhone and cloud phone. Keep physical devices for radio and camera; use cloud Androids for clean, disposable environments.
