At some point they’d probably figure out how to use the accelerometer to fingerprint your movements. Your accomplice will almost certainly have a different profile for how the phone moves when walking. I guess you could limit accomplice activities to things like driving around.

The resolution is probably already there now. AI can do gait recognition based on video, and sensor traces from accelerometers are accurate enough to detect individual footsteps. Are they precise enough to recognize gait? I don't know. But they can easily distinguish between walking, jogging, running, and riding a bike.

And that assumes no CCTV (which will sooner or later be 4k).
