The Pixel fingerprints aren't as unique since only the accelerometer is factory calibrated. >In the case of iOS devices, the SensorID includes both the calibration fingerprint of the gyroscope (GyroID) and magnetometer (MagID). In the case of Google Pixel 2 and 3, the SensorID includes the calibration fingerprint of the accelerometer (AccelID). You can also stop websites from doing this by turning off JS in browsers like Firefox Focus or using something like NoScript. >We only have access to a few Pixel devices,and therefore we are unable to perform the same analysis as we have done on iOS devices to determine whether the fingerprint we obtain for Pixel devices is globally unique or not. The IMU in other Android devices is also likely factory calibrated but the calibration is typically restricted to offsets(i.e., bias compensation). Our approach targets the gain matrix and cannot recover bias compensation. If you want "to be fair", why not mention all these details too?
