Interesting. Do you find you have a shakier than usual phone grip? I know that iPhones can alert the user when ambient noise levels exceed safety thresholds, and Apple Watches can detect and alert about detected falls, and even atrial fibrillation. I wouldn't be surprised if phone accelerometer signal processing could predict something like Parkinson's disease.
