Samsung Galaxy Note 9 announced today that it will no longer be sold by Samsung with a fingerprint reader integrated into the screen, because it cannot be offered by the Koreans with current technologies. This functionality, which will no longer reach the Samsung Galaxy Note 9, will still be offered for Samsung Galaxy S10 next year, but including the company Apple Lossless Audio CODEC (ALAC), is preparing a technology of this kind at the moment, but when it will be launched is not known.
The Samsung Galaxy Note 9 will not have a "standard" integrated fingerprint reader this year, but Samsung is working on a new technology based on ultrasonic waves, and Apple is doing exactly the same for future iPhone models. I also heard last year that Apple is developing an ultrasonic fingerprint reader for integration under the iPhone X screen, but it was no longer offered, just as the Samsung Galaxy Note 9 does not have a "standard" one implemented by the Koreans.
Samsung Galaxy Note 9: Apple Develops the Function Desired by Android Fans
The Samsung Galaxy Note 9 does not have a fingerprint reader under the screen because the technology is too new and ineffective for now, problems with production on an industrial scale preventing adoption in phones sold in large quantities. The same is also true for the technology with ultrasonic waves, here the big problem is the high cost of the components, it being, apparently, excluded from the start for the Samsung Galaxy Note 9, even if a lot of people would have wanted it.
"On the other hand, ultrasonic FOD, which is being developed by Samsung Electronics, Qualcomm and Apple, is a method to capture the minute features of the skin surface using ultrasound. Although the parts cost is rather high and the yield is difficult to secure, it is the most stable technology in terms of accuracy and durability."
The Samsung Galaxy Note 9 is a new proof of the fact that, for now, reading fingerprints through the screen is something very difficult to achieve, and those from Apple know this for sure since they are testing their own version. It is difficult for me to say whether Apple will manage to complete a technology of this kind before those from Samsung, but the fact that it was tested for the Samsung Galaxy Note 9 and removed from the Korean plans shows us that there are great difficulties in its development.
