Kuo said Samsung was still facing "technological difficulties" with the under-display fingerprint sensor.
When Samsung published this patent on fingerprint readers under a display, it seemed like the Galaxy S9 may get one. Kuo says "under-display fingerprint recognition is key for full-screen designs" and doesn't believe that face-unlock systems can "fully replace fingerprint recognition". Before the MWC 2018, we learned Samsung nixed the in-display fingerprint sensor for Galaxy Note 9 and now it won't be ready again. Some of the challenges that Samsung is facing include an issue with screen protectors and other situations that can adversely affect the success rate of the in-display fingerprint scanner. It's in these circumstances that I wish the iPhone X also had a fingerprint scanner on its back like the Galaxy S9 and other Android phones (I now find myself instinctively reaching for it on the iPhone X).
BGR: "Samsung's new Galaxy S9 and Galaxy S9+ are impressive phones, to say the least". Samsung is said to have already tested ultrasonic and optical solutions, but neither have met the company's standards.
That might come as a surprise, considering how Vivo and Synaptics are already singing praises about the latter's in-display fingerprint scanner. Security is the biggest question mark on this nascent technology and is also one of the Samsung's biggest concerns as it positions its phones as something that can be used in highly sensitive cases, like governments and military.More news: IoT vendors urged to ditch devices' default passwords and improve security
However, Synaptics' Clear ID FS9500 isn't good enough for Samsung. Ming-Chi Kuo now expects Samsung to bring the feature to market in the first half of 2019 at the earliest. Instead, it will introduce new products and technologies when they are ready.
To get a better idea about what's coming with the Galaxy Note 9, just take a look at the Galaxy S phones that Samsung just launched - the bigger handset is likely to be much the same, with a few minor improvements here and there.
CNET: "The Galaxy S9 is a nice incremental upgrade, but its low-light camera isn't a game changer and some new features fall far behind the iPhone X".
Kuo himself is not a believer of face recognition, no matter how many times Apple preaches it.
