Probably one of the biggest gripes when it comes to the latest Galaxy S8 and Note8 series is its fingerprint sensor. Because of its 18.5:9 Infinity Display, Samsung had to remove its physical home button and the fingerprint sensor is now moved to the back of the device.
It wasn’t meant to be this way and Samsung had originally planned to integrate its fingerprint sensor underneath the screen. Unfortunately, Samsung had to scrap this implementation purportedly due to the unbalanced lighting of the screen where the embedded fingerprint sensor is located.
According to a note that’s reportedly sent by analyst Ming-Chi Kuo of KGI Securities, Samsung will overcome this technical challenge in 2018 but it won’t appear on their next flagship.
