Exactly how the software update will fix this problem is unclear, but until the update comes out, Samsung suggests that everyone use the company’s official screen protectors. Plastic screen protectors work best with the ultrasonic fingerprint sensor on Samsung’s flagship phones, as thicker screen protectors make it harder for the sensor to detect fingerprints because of the gap they create between the display and the user’s finger. Some liquid adhesive-based glass protectors overcome that limitation, but Samsung is unwilling to put its seal of approval on any but its own screen protectors.
