One of the renowned analysts who expected Samsung's Galaxy Note 9 to be able to implement in-display fingerprint recognition tech in the first place no longer believes that's the case.
What's good for Vivo may not be good enough for Samsung, which is reportedly sticking to a conventional fingerprint reader mounted on the back of the Galaxy Note 9 due to in-display development woes.
Samsung may need several more years to replicate Apple's Face ID magic, but in the meantime, the Galaxy S9 should sport a beefed-up iris scanner.
Is the security of iris recognition technology on the Galaxy S8 an "issue"? Probably, although Samsung thinks a hack is difficult to happen in reality.
There's no such thing as an infallible, impenetrable biometric authentication system, at least not on the Samsung Galaxy S8.
You'll probably have to wait a few more years before securely authorizing mobile payments with your face, at least on Samsung devices.
In addition to fully supporting the world's three fast-growing mobile payment apps, Mastercard has been working on its own evolved biometric card.
