under-glass fingerprint

update3.0: vivo and huawei phones use optical technology to scan the fingerprint through the display, samsung presented a prototype of the company’s ultrasonic fingerprint reader

update2.0: samsung’s s10 should get in screen fingerprint reader, like vivo and at the same time iphone like face recognition

update: samsung’s s9 still not provided in-screen fingerprint reader, vivo updated with dual fingerprint scanner

since samsung had to replace the 2. camera to place with the fingerprint sensor, because couldn’t provide under-glass fingerprint in S8 – vivo is the first company to reveal this feature, while S9 will launch in about one month
