I used to work on diesel engines. I'd end up with different looking fingerprints all the time from grease, oil random little cuts, etc. I'd hope this tech is better able to discern fingerprints from noise. It was a little annoying.
It might not be. If your fingerprints are physically changing, then an accurate scanner should not recognize a fingerprint that's changed after the fact. If anything you're looking for a less accurate scanner to help with this issue. But a less accurate scanner could let others in your phone too.
A family member is a massage therapist and no fingerprint reader has managed to recognize their fingers. Not even the old capacitive types in the rear. They don't even recognize there's a fingerprint present. It's like tapping with a wiener.
1.) Used to be a dishwasher and even the government had a hard time getting my prints.
2.) A wiener (that's attached to a human) can actually be used and make a recognizable print on a fingerprint reader. (Not recommended for daycare workers.)
Someone took their wingerprint
Now I wanna set up my phone to accept my wiener.
Don't let your dreams be dreams.
If my dreams can't be dreams, they can't be anything. Reality doesn't support what matters to me.
The tech has been in Samsung phones for several years, and is good enough that one's fingerprint will read through vinyl gloves if they aren't too scrunched up. It's fast and decent.
Does make me wonder though, it's a Qualcomm tech. Does that mean Google is finally going back to Qualcomm chips? The pixel modems have been trash ever since they left.
Yeah, I instinctively tried to open mine with vinyl gloves on once and immediately thought "I'm dumb, gotta take these gloves off first." That was a good shock when it actually worked first try, much confusion...
It makes sense if you think about it, ultrasonic vibrations will "see through" the glove and detect the finger ridges beyond. If the glove is scrunched up, it "looks" like finger ridges that aren't yours, which will then not match.
That's exactly why I'd hope an ultrasound would ignore things like color difference. I wouldn't expect it to ignore cuts without an ai component.
I've done so much work with my hands. I thought something was wrong with my phone, my partner walked up finger on phone, opens immediately. Me, half the time I need to use the code because the fingerprint doesn't work.
Exactly. I used to register my off hand, as that was a little less likely to get damaged.
The problem is I'm prone to accidents so my non dominant and has scars from cutting myself.
My fellow diesel tech. Fucking yes this fucking problem right here hahaha. Skin peels a bit, little scratch or cut, got some shit on my hand to dry it out.... And whole new finger print. Add this print, and once it hears it stops working again. Hahahaha fuck my life.
My galaxy s24 has been pretty spot on though, honestly works most of the time unless my hands are very dirty.
Me too, the random little cuts are by far the worst because it can take weeks until the phone registers your fingerprint again.
Thank God it allows for more than one finger. I used to start running low on undamaged prints!
Hmm, for your use case face unlock should be more reliable.
If you thought my hands were dirty...
What if you used a part of your palm instead of a finger?
I solved the problem by getting a better job, but at the time, it wouldn't have helped. Same problem. Swimming in motor oil.
