You must have had better luck than me.

- Xiaomi Redmi Note 4 - pretty good finger print scanner on the back

- Samsung Galaxy S8 - absolutely terrible fingerprint scanner that was so bad I switched to pin after a while

- Samsung Galaxy S10 - new fingerprint scanner under display, works most of the time but still unreliable, also it is not the quickest.

You would have thought that leading brand (Samsung) would have decent fingerprint scanners on their flagships, but it is just not the case.

The thing with bad fingerprint scanners is that you cant rely on them, so I rather choose reliable slower 3s unlock with pin than unreliable maybe faster 1-10s unlock with fingerprint.

On my S8 I never used the rear fingerprint scanner. It was so unweildy and poorly placed that it was quicker and easier to enter my pin.

They also touted "face recognition" but it was a poorly-made piece of software that used a conventional camera (no depth) and was just a marketing check-off item, and not a real feature.

Yeah, all my phones have been Xiaomis where the scanner is fantastic. The latest one, the 9T, has an in-display scanner, and you're spot on. It's usually okay, but sometimes gives me trouble, and this burstiness is what irritates me to no end.

My LG V20's fingerprint reader works quite well, and is rather fast. It's also a couple years old, but still zippy.

On my S9 they seem to have hit the sweet spot -- there's little to complain about.

3 seconds?!

Click the lock button, swipe up, enter the pin. Seems to be about 3s?
