Several methods are described to achieve this. For example, the devices might force you to touch the fingerprint scanner by placing one of the required digits over the sensor.

Such a sensor will be able to scan your print no matter the code, password or pattern you enter.Interestingly, we recently saw rumors about Samsung seeking a larger fingerprint sensor for the upcoming Galaxy S11. Still, we do not want to jump to conclusions here, as it remains notoriously hard to predict if and when patented ideas will become reality.
