Galaxy Note 9 without finger print sensor.

Samsung is not coming up with the finger print recognition system in their flagship phones was a rumor according to KSI Securities research analyst Ming-Chi Kuo.

The rumor to his previous prediction over canceling  the finger print might be  due to technical issue and Samsung will cancel this feature on Note 9 because both ultrasonic (provided by Qualcomm) nor  optical (provided by Samsung LSI,, and Synaptic) solutions is not  meeting the  Samsung's technical requirements.

Even so the excuse over technical issue, KSI also believes that the under-display scanner will not cut off.
 He also believes that in few years most of the Android user will be switching to the LCD face detection feature over the under- display finger print OLED panel. It’s kind of rumor that we are getting I guess.
