I recently purchased a Samsung Galaxy 22 mainly for it's excellent camera.

Not too happy with the biometrics.

On my old LG-6, the fingerprint sensor worked perfectly but my new phone
is very poor.

There is a sensitivity setting that I set to "increased" and I tied it
both with and without the screen protector. I have to touch it ten times
to even get it to register once and it took me forever to get it 100% setup.

Most of the time when I try to use it, it fails.

I registered a 2nd fingerprint using my left hand and it works
*slightly* better.

I also have face recognition set up that works just slightly better.

The camera is so good that there is no way I'm going back to my LG, but
I wonder if anyone here knows any secrets.

Thanks

So, from that I'd say you're a bricklayer with a plain, unrecognisable
face. ;-)

I'm a baldy who looks just like a billion other old bald men :)

Face recognition works better than fingerprint.

What peeves me is the LG-6 was flawless.

Not the end of the world but...

If your fingerprint worked flawlessly with the LG-6 then it's got to be a
problem with the S22. I suggested you might be a brickie because they often
have problems with fingerprint scanners due to the fact that their job
entails handing rough bricks that affects the deepness of fingerprint lines.
As for being bald, well, I have to use 2 mirrors to see the 2" strip I've
got around the back of my head as well. And besides, Yul Brynner was did
better than Victor Mature on and off screen.

I'm quite surprised that your S22 is mucking you about though because mine
works flawlessly, like your LG-6, even with my wife's fingerprint which I
usually add to my phones so she can open them while I'm driving or having an
afternoon nap. I'm not going to add insult your problem by asking if you've
tried restarting your phone or performing a factory reset.

Register the most often used finger a second time. This usually improves
recognition of the fingerprint of this finger massively.

> I also have face recognition set up that works just slightly better.

Use it as often as you can. There should be learning algo behind it.
That's what happens on my Pixel 7. This function is OS-based.

I've of course rebooted but will fool with it more when I have time.

no need to do a factory reset as the unit is brand new

Unfortunately, as biometric security has improved, false negatives have
increased.

Fingerprint sensors used to be 2D capacitive. Now the under-screen
fingerprint readers are 3D ultrasonic, which are much more secure, even
more secure than facial recognition, but with more false negatives.

I have a Samsung Note 9 whose capacitive fingerprint sensor, on the back
of the phone, is great in terms of unlocking the phone nearly every
time, and I prefer the location on the back.

I have an iPhone 11 whose FaceID is real pain since so many times it
doesn't unlock and I have to enter a six digit PIN, and of course during
the height of Covid, when everyone was wearing masks, it was even more
of a pain.

false. the under-screen fingerprint readers are *less* secure, slower
and less reliable than a capacitive sensor and certainly apple's face
id or google's equivalent on the pixel 4, both of which are much more
advanced than simple face recognition. it's also easy to spoof an
under-screen sensor with adhesive tape or reflective foil.

<https://www.androidcentral.com/in-screen-fingerprint-sensors-suck>
Being slower than regular fingerprint sensors is the best case
scenario. The worst is having these in-screen sensors regularly
misread your fingerprint, requiring you to give multiple attempts
before your phone finally unlocks.

to be fair, the under-screen sensors have improved a bit since that
article was written, however, they are still nowhere near as good as a
capacitive fingerprint sensor nor anywhere near as fast or secure as
apple's face id. unfortunately, google has discontinued their face
unlock (the pixel 7 isn't the same) so that is no longer an option.

you're lying. you didn't have that phone during covid, plus face id was
updated to handle masks.

That might be the least of your problems, once Google
and Samsung finish selling your data, and the FBI computer
thinks your blurry fingerprint is a dead ringer for the guy
who robbed 6 banks in 1987. :)

The 2d capacitive fingerprint reader on the the LG G6 is very different
than the 3D ultrasonic fingerprint reader under the screen on the S22.
The former is less secure but less prone to false negatives. The latter
is more secure but more prone to false negatives.

My Pixel 7 is absolutely no match for the Pixel 4 it replaced as far as
fingerprints are concerned.

Face recognition on my iPhone 11 is at a completely different level
compared what is used on Android. The technology is much further
developped. On my Pixel 7 with Android 13 face recognition is very
unreliable compared to the iPhone or the Pixel 4.

*What does it matter if one gimmick is more or less secure than another?*

What are people so afraid of that they feel their wives, their children,
their neighbors, their coworkers, everyone around them - is going to rip
the phone out of their hands unless they secure it with their fingerprint?

*These silly marketing gimmicks play to their unsound unhealthy paranoia.*

Obviously you do not know how to operate the iPhone correctly.
My iPhone 11 never fails but my Pixel 7 is not really good in this
discipline.

Well, despite their high price they're quite a common phone, so I suppose
the only thing left to try is to ask someone you know if they'll let you try
setting up your fingerprint temporarily on their phone before your 2-week
cooling off period comes to an end, that's if you brought it online, of
course. Because, like I say, I don't think I've had a single instance where
my fingerprint sensor has failed me. In fact it works so flawlessly I'm a
bit suspicious it's wide open for anyone to open it. I use Lastpass on my
phone with fingerprint security, so I'm a bit anxious about that as well.
I've got my whole life's security on Lastpass. Good luck!

Well thanks for that, because up until now I didn't realise the intricacies
involved behind fingerprint scanning and their changes. It's just one of
those things I've come to trust without putting much thought into it. Are
fingerprint scanners a trusted form of security, in your knowledgeable
opinion?

What threat are you protecting yourself from?

The only reason for biometric security is to protect your phone from people
close to you, such as your wife, your kids, your friends & neighbors.

What slum do you live in that you feel you need protection from them?

Why data theft, of course.

If you read the thread you'll find that I've registered her fingerprint on
all my devices:

"even with my wife's fingerprint which I usually add to my phones so she can
open them while I'm driving or having an afternoon nap."

>your kids, your friends & neighbors.

Well yes, of course. I don't think it's a good idea to give a teenage
daughter access to credit card data, especially if she has a taste for
expensive items and a life-long notion of having a dad with deep pockets.
