Earlier in the day, a report suggested that the Samsung Galaxy S10 will ditch the iris scanner that debuted with the Galaxy Note7 in favor of an in-display fingerprint sensor. Apparently, the technology has matured enough to work well on its own. Now, new details have emerged about the in-display fingerprint scanner that would be used in the Galaxy S10.

Most companies use an optical in-display sensor in order to stop costs from ballooning, but Samsung will reportedly opt for an ultrasonic sensor. However, earlier reports that we covered suggested that the entry-level variant of the Galaxy S10 might stick to an optical sensor, while the remaining high-end models will ship with an ultrasonic reader.
