As per popular Chinese leakster @Ice Universe, both Samsung and Apple are facing some issues with the in-display fingerprint scanner.As days are nearing towards Samsung is unable to implement the optical fingerprint scanner in the Note 8 so finally, Samsung decided to move with a rear-mounted fingerprint scanner.As Samsung Galaxy S8 & S8+ had a weird position of the fingerprint scanner, even many of the user complaint that while accessing the fingerprint user will touch the camera at the back. So, now Samsung will place it in easily accessible location probably below the camera.
Hope Samsung implement the optical fingerprint scanner in Note 8 and might launch with that feature. For now, we have to wait for few more months to get more details regarding the same.
