Galaxy Note 9 is just a few weeks away, but it's 2019 that turns out to be a really exciting year for Samsung. Rumors say two distinct Galaxy flagships will be unveiled in the first half of next year, including three Galaxy S10 models and Samsung's first-ever foldable Galaxy phone. The success of the Galaxy S10 is critical to the company, given that the Galaxy S9 has not performed well as expected and that the folding handset will be an expensive niche phone available in limited amounts in the first year.  The Galaxy S10 will mark the 10th anniversary of the first Samsung smartphone created to compete against the iPhone, and it's a phone that is expected to bring about several significant improvements and design changes. In fact, a new report triggers a Galaxy S1
We've seen it in patents before, including documentation describing Apple innovations, but this invention has not yet been used in a smartphone. I'm talking about an ultrasonic fingerprint sensor that will rely on ultrasound to read fingerprints.
Two Galaxy S10 releases released next year will contain a screen with an ultrasonic fingerprint sensor embedded under them, Digitimes says. If this sounds familiar, it's because a similar reputation last week claimed the same. The Taiwan-based tech blog now reports that Samsung has been reluctant to place order for iris recognition chips for the Galaxy S10. Industry sources also say that ultrasonic fingerprint sensors are meant to distinguish Galaxy S10 from competing devices, including iPhone X, which uses Face ID technology, and Chinese smartphones that have optical fingerprint sensors on display.
Galaxy S10 comes in three sizes, report notes, including 5.8, 6.1, and 6.4-inch. The smallest model will have a rear mounted fingerprint sensor as its predecessor – previous reports said the 5.8-inch phone would pack a fingerprint sensor on the side.
On top of the two Galaxy S10 versions equipped with ultrasonic fingerprint sensors, Samsung will apparently launch two other phones with similar features including next year's top-of-the-range Galaxy A model and 2019 Galaxy Note.
There are more evidence that smartphone manufacturers are looking at this fingerprint sensing technique. GIS chairman Chou Hsien-ying said his company will begin volume production of ultrasound in-display fingerprint modules in the second half of 2018. Several 2019 smartphones will have fingerprint sensors embedded in the display, whether they are optical or ultrasonic, the sources said. But the Galaxy S10 may be the first smartphone in the world to go for an ultrasound version and it's good news for Samsung fans because it's going to offer better performance than an optical sensor.
