Apparently, Samsung no longer seeks to use a fingerprint sensor on the screen for the Galaxy Note 9, according to a research note by KGI analyst Ming-Chi Kuo, through AppleInsider.
Originally, Kuo had speculated last August that Samsung was looking for the technology for the next Note 9. The company failed to include the feature in recently launched Galaxy S9 models, which featured a more traditional fingerprint sensor on the back of the device. But according to Kuo, Samsung is apparently delaying the function of the models this year due to problems with power consumption and the sensors do not work reliably with screen savers or in different environments.
If Kuo's report is accurate, that would leave Vivo as the only large smartphone company until now that has fingerprint technology on screen in a phone. The company showed the sensor with much fanfare at CES 2018 earlier this year in collaboration with Synaptics, and announced the X20 Plus UD, the first smartphone with the feature, a few weeks later.
