Samsung Issues Software Patch to Fix Screen Protector Flaw in Galaxy S10 Fingerprint Sensor

[csurfr]

Not mistaken at all. It’s irrelevant as to whether it’s a case or simple screen protector. The fact it gets “learned” as a fingerprint because it has some sort of pattern is the issue.

You said:



The sensor on the Samsung is tiny. I have an S10 and Note 10 and have seen it by shining a light on the screen at the right angle. Do you own either of these devices? Have you ever learned a fingerprint on them? The instructions tell you to move your finger around to capture your entire fingerprint. It even shows the same animation Apple uses for TouchID that shows your fingerprint being “filled in” with subsequent touches.

It’s a huge flaw that Samsung sees a pattern in any type of screen cover and isn’t smart enough to realize it’s the same pattern over and over during registration. I guess Samsung was lying when they tell users to “move your finger to capture the edges of your print”. So what’s Samsung doing when they “fill in” your print during registration when all they see is the same pattern over and over? Lying?

Hahah. So now because the animation shows a fingerprint you think the phone is lying to you? It’s a progress bar

And yes, I have an S10+ and a Note 10+, along with an iPhone 11.

So then all your comments are BS if you claim you own these devices AND can’t understand what I’m saying.

Samsung has a huge problem with their registration algorithm if it can’t tell that the user hasn’t moved their finger during registration (like it tells you to right in the registration screen).

The silicone “cover” isn’t glued to the screen. What part of that are you missing? It is always going to bend and stretch a little bit. Apparently enough to make the sensor think it IS moving.

Have a good day.

Not good enough. The cover isn’t going to move that much. Maybe a millimeter tops.

Samsung failed miserably for seeing the same pattern over and over and the software being too stupid to realize it and let you finish registration anyway.

And don't forget Google with their faceID without eye focus. Good thing Apple never does things like that and then drags their feet fixing them (if only I could get my MacBook keyboard keys to all work...).

Yeah I have to give it to Apple, biometric security is something they’ve always got right.

kind of makes you wonder how exactly an air gap can fool the sensor. doesn’t the sensor need to read certain values to check against the saved fingerprint to see if they match?

Exactly. This was a huge security flaw.

 

[Justanotherfanboy]

It’s not an air gap that is fooling the sensor.

Just as some (most) clear cases have a texture to prevent the phone from having that wet bubble look, the “screen protector” in question has the same thing. The fingerprint sensor is reading that texture as the fingerprint during registration, not the users’ actual fingerprint. So, with the texture being read anyone can unlock the phone, as that pattern is what was actually registered.

I was highly interested in this development & thought I had read coverage fairly in depth... I remember precisely zero news outlets describing the situation how you did.
Even as far as random uninformed theories, from layman users- I never saw anyone guessing that the situation arose as you describe.

Your missing the example where the fingerprint was registered without a screen protector and placing a case on the phone allowed a different finger to unlock it.

How do you explain that?

I highly doubt that.
When I applied a protector to my s10 I had to re-register prints since none were detected with the protector.
Even with re-registrering, detection was really flaky. I had to remove the protector since it would only unlock the phone every tenth time or so.
There must be some special protectors that cause this. My experience shows that it's very difficult to get any prints read with a protector. The phone won't unlock at all.

There's a video demonstrating exactly this.

Regardless, that's only one issue. The real issue is the absolute stupidity of Samsung allowing you to register a print with a screen protector (that apparently has a pattern or latent image on it).

But when will Apple fix Face ID?

When will you stop lying?

You've only posted this exact set of links countless times and had them explained to you each time. Yet you continue to post lies even after being corrected.

You keep posting this as if it were the same in scope and severity. It simply isn't.

One word.

Fingergate

It would be interesting to see what’s the real cause here.
With so many people on YouTube reviewing the Galaxy S10 series, why aren’t there as many videos showing or testing this issue? Were all people with S10 on YouTube simply using review units and nobody actually bought one?

Release notes from the patch. I posted them on page 1 I believe.

Oh..... gotcha.
So you’re saying that’s what Samsung claims occurred, not what consumers actually experienced.

Your username fits that quote perfectly.
