We still have a leak to add to what is already a series of reports suggesting that the Galaxy S10 will be a really important release for Samsung, with the S10 as the handset's most important innovation in years.
In addition to the recent round of reporting that suggests that three Galaxy S10 models are coming, a report from South Korea says that all three will have a new in-display fingerprint sensor. This is different from earlier reports that the technology would only come to two versions of the S10, with the exception of the entry model.
The news site aimed at Samsung SamMobile zeros from there on a few differences in how that technology will be implemented. The two models with a higher end, the site notes, will receive an ultrasonic display-based fingerprint sensor that may be supplied by Qualcomm, while the entry variant has an optical sensor.
The ultrasonic sensor "works by sending an ultrasonic pulse against the finger to map the pores and ridges unique to each fingerprint," the site notes. "Ultrasonic sensors are more accurate than their optical counterparts because improved 3D display of the fingerprint is possible using the additional depth data collected."
An optical fingerprint sensor, the site continues, works instead more like a digital camera to capture 2D fingerprint images. If a finger is too wet, dry or dirty, it may damage the accuracy.
As part of this latest, juicy rumor, Samsung's successors for the Galaxy S9 and S9 + will also receive a 6.2-inch curved Infinity Display for the former and a 6.44-inch version for the latter. Those were the two who previously expected to get the fingerprint sensor in the display.
Of course, Samsung has not yet confirmed the launch of the three reported S10 models, nor the existence of a fingerprint sensor on the display, so it's best to keep this in the category of rumors. Yet it is still a reason to be enthusiastic about 2019, when the S10's are likely to be available just like the very first foldable Galaxy phone from Samsung.
It will be a big moment for the company, with the S10 also reportedly marking the 10-year jubilee of the first smartphone Samsung has made to compete against the iPhone. The larger screen of course took the rivalry of the two manufacturers to a whole new level and helped to restore consumers' expectations about screen size.
Another reason 2019 will be the key for Samsung: the company needs the S10 to become a hit, because the S9 did not do as well as expected. The availability of a foldable phone will certainly cause excitement, but it will also be an expensive niche release and initially available in limited quantities, making the S10 more under pressure to perform well.
