Samsung Admits Major Security Flaw in Galaxy S10 Under-Screen Fingerprint Sensor

Huh, maybe Apple were onto something, avoiding under screen and going with FaceID after all.

Not sure how this can be fixed by a software update – it sounds like a physical problem, but what do I know?

Probably the same way they tried to fix the GPS issue (it was later revealed to be a physical design flaw) in the original Galaxy S. 😂

For the record, my persistence disdain with FaceID is that I do motorcycle touring to the tune of 12K+ miles a year and had to go back to a 4-digit passcode because while my gloves work with TouchID & the touch screen, my helmet does not work with FaceID so when I need to do anything I used to be able to unlock but now I have to stop and remove my helmet or type in a passcode. this has been going on with me for 3 years and I hate it every time.

It took three times to train my phone to unlock when I was snowmobiling and wearing a helmet.

Fake news! Apple lacks innovation! /s

This is interesting. Did the original oner need to authenticate at least once with the screen protector? I'm thinking that the gell screen protector is soft enough to form similar ridges as the fingerprint, and subsequent pushes, regardless of the finger, will force the sensor to detect the pre-molded ridges.

I guess the optical ones are still better?

My first suspicion when the story broke, was that a fingerprint was trapped between the screen and screen protector and the sensor was reading that. Maybe its just horrifically bad code that allows a failed read to unlock the phone. Seems crazy that you would write it like that.

That was my first thought too

mounting it on the dashboard facing your face solve the problem. And you should not be using your phone while driving anyway.

Well you quoted me saying "drinking" and changed it to "driving", so this doesn't really apply to my situation. Freudian slip, drunk driver? :p kidding
 
It probably happens to other android phones 😏😋

I own a Note 10+ 512GB. The screen looks amazing with a tiny hole punch rather than gigantic notch. Also, having Dex computer built in is where Apple is currently missing the boat with its A-series SoCs. And USB C, is where it’s at. All that being said, if this is not correctable via a software fix, this is a bigger fiasco than Apple leaving MacOS Admin account wide open with no password needed. Or iOS FaceTime allowing eavesdropping. This better be fixable via a software update, or it renders the phone worthless via biometric access. Can you imagine if Apple’s FaceID has this problem???
 
So basically if you use a cheap screen protector any fingerprint will unlock the phone? The easy fix for this is to simply buy a higher end screen protector. I don't get why this is a big deal if anything that cheap gel should be discontinued and there problem fixed.

That sucks... I hope it isn't an indictment of placing it under the screen as a whole.

Separately... why the hell do people use screen protectors anyway? They're beyond useless, feel strange, break so easily that people try to justify owning one with them, and look awful.

I agree. And then they do break, and they don't bother replacing them and just use them cracked. Like, what's the point if you're not going to just peel it off and put on a new one?

I haven't had a screen protector since, I think, the 3G, and have had less broken screens than a lot of people I know that put them on.

To me DEX is a half baked solution.

The other bugs mentioned, FaceTime, macos they were able to be mitigated somehow. This f/p bug allows someone to rip the phone from your hand and gain access.

malfunctions with a small air gap, so the default is to accept as successful in these cases?? They'd still be generating minutia and those minutia shouldn't match. This is a pretty ugly bug.

edit to add: there has to be more to this. Did the person enroll while the screen protector was on? I can't imagine having a good set of minutia and then placing a screen protector in place and subsequently having it fail in this manner.

Exactly my thoughts... I don’t have a PhD in electronic security measures or anything, so take my opinion with a grain of salt, but “I can’t make heads or tails of what I’m seeing, so let them in” doesn’t sound like it should be on the list of best practices...
