Samsung A50 Latest Fingerprint Update - Samsung Galaxy A50 Guides, News, & Discussion

New update received for my samsung A50 (SM-A505F/DS). I received it yesterfay. After the security patch update of november this is the second update which brings
Improved fingerprint recognition algorithm
The update size was 112.12 mb
Video Here
I noticed amazing improvment in fingerprints recognition after this update. It's just a super speed. In my another post Super Fast Fingerprint trick for A50 I showed you a trick which gives you a smooth and fast fingerprint scanning experience. And after this update, the combination of these two ( my Trick and the update) are just awesome..
I Didn't find any other new feature or update but the fingerprint recognition is quite accurate and fast now. A lot better then before.

After today's second November update, the accuracy of reading the fingerprint sensor when inserting new fingerprints has been significantly reduced. Either the sensor constantly warns you that your finger must cover the entire area of the sensor or prompts you to clean your finger or the glass of the display. These problems mainly concerned my right thumb when the other fingers were able to enter the cecek without major problems. The whole desperate I tried the method described here on the forum already described somewhere and within the scope of one fingerprint I alternated on the sensor and four fingers of one hand. All I was surprised to find out that I have registered a total of eight fingers at once and everything works great. Please try it, it costs nothing, just a little time.

[Q] Why my fingerprint scanner is so awful?

Hi, question: i have a Note 10+ with all updates and updated via adb to Android 10 but my fingerprint scanner is still really awful. I have seen all yt video, seen all tuto on how to set the fingerprint but nothing!
Still awful, especially when finger is a bit wet. Is there a solution or is it better change the phone?
Maybe it is the way you registerd your fingerprints, my fingerprint sensor is accurate all the time
Are you using a screen protector? Mine sucks too. I have a glass one with the thin area in the glad over the sensor and I have used privacy film and it's ehh. It works perfect with nothing on it. Try turning the touch sensitivity up in settings and maybe re-register the print again.

(The touch sensibility have nothing to do with the fingerprint sensor though.)
Maybe they finger print again but dont press to hard
Upside down

You probably have, but try registering your fingers upside down and side ways.. and register loads of times with the same finger you mainly use, im sure you know all this though
It's awful, specially compared to the OnePlus6T

, no, it is not, mine as many others work just fine, the fingerprint sensor for whatever reason doesn't work the same for all, odd, but not a so uncommon issue, and this happens among all brands
I partially blame the size of the sensor as well as the way they guide users through the enrollment process. The standard android fingerprint enrollment process, as i've experienced on my HTC U11 and Razer Phone 2, prompts for more finger edge samples. I actually went through the process on the Note as the software prompts and had mixed results. I then just decided to hit the sensor randomly with some overlap to give it a better overall picture of my finger as opposed to a bunch of samples of the same spot and then a few variants.
If you shine a flashlight at the screen you'll see the sensor size. It is a short rectangle that doesn't seem to cover the area that the fingerprint icon covers. I have an amFilm whitestone-style screen protector and while there is a slight difference, the stock experience was also not that great. I would recommend you try to figure out how you ACTUALLY use the fingerprint unlock. I noticed that while i'm enrolling i'm focusing on pushing with my fingers dead-on, in practice i actually use just the upper right corner of my thumb (if you're looking at the fingernail top-down). When I realized that I trained it with that in mind and it did perform better.
There was mention of the ones in the One Plus devices, which are actually different in that they are optical. Because they light up and read optically they have a more controlled environment than what the ultrasonic sensor on the Samsung phones. I can see someone with a deeper fingerprint patten be able to get better results vs someone with a very faint fingerprint. On oneplus devices though it would just be a different picture, but i'm thinking on an ultrasonic sensor there might not be enough peak and valley information to pass the threshold. Maybe samsung can make the pattern require less data points to match to unlock, but that would also mean it is less secure.
Bottom line is that while the tech has the potential to be more secure than optical under glass, it still has a little ways to go but it is serviceable once you get to it. I don't have big hands so i have to hold the phone in a very specific way to get a good grip on it. Once i figured that out, training the sensor again did yield better results.
I have the same problem. In sorry you haven't received a resolution, especially from Samsung who manufactured the Galaxy Note 10 Plus. I'm believe they were aware that it did not work with many 3rd party cases with protected screen covers. No matter how you register with screen off or on, the reader is intermittent and doesn't work with the cover. I hope you get the resolution as it will solve my issue as well.
The fingerprint registration process seems very glitchy too but after having experienced an awful 40% success rate with waking the phone using my fingerprint I deleted all the stored prints and started again. The secret is in storing decent prints so keep doing this until the phone unlocks with a 90%+ success rate like mine does now.

Fingerprint sensor

Everytime I see videos about the Note 10+ under screen fingerprint sensor, usually YouTube. They quickly go to the sensor, just briefly touch it and their phone unlocks. I have to press screen firmly, hold it there for about 1/2 or a full second, then it unlocks. What am I doing wrong
I see there same results
Hard to say, mine works super fast, but in fact I do not use any type of unlocking security! I never leave my phone unattended, and I have no sensitive content stored in it, so…
Mine works great even with Whitestone screen protector. What I do when registering, I use left thumb, then right. I do this until 1st print is registered and continue the same for 2and 3rd and 4th

I find it to be pretty poor compared to normal fingerprint sensors but does the job for the most part. It was definitely better before I installed a Whitestone screen protector, comparable to the optical unit on the ROG Phone 2.
I find a quick tap does sometimes work but most often I get a message to say press harder or something similar.
Coming from OnePlus 7 Pro..this FP sensor is just horrible...I can't even get it to unlock 50% of time
2 things: you can change the screen sensitivity and that may help register with less pressure or time spent pressing. Also, I would remove the troublesome registered print and register again. Make sure you aren't pressing super hard during registration, and get every angle and position of that finger possible.
Doing this, I've had no issues with using the reader.

I still struggle sometimes with the fingerprint sensor not being always dependable 'at will'. It's a great phone, but this problem is very frustrating to me, too much of a contrast to this phone's all other qualities.
Now in the Winter the problem gets worse, dry air=dry skin, at home I can use some hand moisturizer(it helps), but I don't think that's what the sensor designers hoped for to improve sensor's reliability.
I'm on it since S10 which I returned for the very same reason shortly after purchasing it about a year ago and replaced it with S10e, a phone that was perfect and free from my frustrations. Yet I swapped the S10e for N10+ just to have a bigger screen for reading my ebooks on it. Somehow I convinced myself that the sensor will have totally new hardware. Well, they did improve the software, the sensor in N10 is the same, more accurate in my opinion though, but it still lags behind expectations for a flagship, or rather, as I call it referring to its price: a battleship.
So, my new resolve now is to aim for S11(it all depends on Samsung's generosity with the N10 swap), not much”leaks” around about the S11 specs but I think they have a brand new and bigger, ultrasonic sensor in the works.

I removed my existing fingerprint registrations and did it as you suggested, 4 times slowly without to much pressure.
Now my fingerprint function is working flawlessly without any issues.

S20 FP Sensor is very bad - any help???

Hi everyone!
I'm a owner of a new Galaxy S20! Nice, small design, everything is working fine - execpt the Fingerprint sensor...
It is very bad, i scanned the same finger 3 times (as three single fingerprints) but it is still very bad in recognizing my FP! And the speed of unlocking isnt as good too...
Coming from an OnePlus 7t, i am defenitly shocked
For that price as a flagship i expect a bit more...
Maybe some of you can help, or have tips for me for "tuning" my FP sensor!
Thx a lot!
Not really. Making sure your hands are clean helps a lot - it's reading the raised section of your fingerprint as they press against the glass, if your hands are dirty the crevices get full and make it harder to see them.
To be fair, the first gen optical sensor on the 6T and the slightly improved one on the 7T 7 Pro are literally just cameras that compare photos to ones in memory. They're fast because they aren't super accurate. The ultrasonic ones on Samsung devices are more accurate but slow and finnicky. Honestly, I preferred the old style ones on the back, they were better in both regards.
It's slow and usually fails a couple of times on me as well. I switched to using face recognition and I'm very happy with it... I was surprised at how quick it is.
I have scanned my finger twice as well as added face unlock, and works pretty much always
Turn off Optimize Battery Usage for com.samsung.android.biometrics.app in Settings.
I have really dry hands (fingers). Usually takes me a few tries to unlock. And yes I've done all the tricks to try and speed things up.
Taking off the screen protector helps a lot, but ya its as bad as the s10 one.
Scanned my finger 9x's today before it decided to say "oh yeah, I know you." Coming from a OP7 PRO 5G, this is absolute garbage! Going to disable it and try the face recognition.
I am having similar issues. A couple of things that helped:
- disabled battery optimization for com.samsung.android.biometrics.app
- re-enrolled the finger (once) while holding it longer and at a different angles
I am also trying to train myself to touch and wait patiently until it unlocks.
Face recognition is not great imo...
If I disable biometrics app battery optimization and remove fingerprint animation it seems to be a little snappier. I came from 7pro and op has a larger sensor but I got used to s20+ and don't have any issues as long as I place my thumb on the right spot lol.
I left the stock screen protector it came with and I have no issues at all. I see a lot of people complaining that it doesn't work or that it sucks, but i personally love it. NEVER going to use face recognition or whatever else is there.
Same problem
Multiple presses to get in on 2 fingers. Phone keeps telling me to press harder!?!?! The phone will go back to Korea if press any harder.

Question Poll: How well does your Pixel 6/6 Pro Fingerprint Scanner work?

I made this thead poll as a guideline so we can see how many people are/aren't having issues with their FP scanners. If you are having issues what are the main issues?
I really don't have an issue with it and if Google's response to it's slow because of extra security then I'll take security over nanno seconds delay in unlocking my phone. Now that I have removed all the fancy useless animations, like I do on my phones it actually just seems as fast if not faster then on my S20. Yes when I 1st got my pixel 6 pro it did seem slower especially when like myself you have come from having Samsung flagship devices, I think a lot of the problems come down to muscle memory and now I've had my device for a couple of weeks I hit it bang on 9 times out of 10 just like my on my previous devices. It does what it's meant to do and that's secure your precious data on your phone. I wish I had a 3rd device so I could do a comparison video to demonstrate my unlocking experience.
I had a Galaxy Note 20 Ultra. Switched to Pixel 6 Pro and the fingerprint sensor on the Pixel, for me, is much better!
I set them up the same, but I like that the light shines through my thumb, it makes it more obvious that I have it right. For me the Pixel is better, much better.
Works as well as my OnePlus finger print reader, just fractions of a second slower.
Not had to change any setting such as animations for it to be reliable and just work.
Been fine for me, I'm guessing those having issues have small fingers.............I'd still prefer one on the back
works alright for me, but definitely not as instant unlock as I had on the 4XL. sometimes though I need to hold my finger on the screen for a second and a half to unlock, but most of the time it's quicker
You needed another option between 50% and 95%. Maybe "most of the time but not quite 95%" None of the three options fit my experience, sorry. Oh yeah, one more. "I use smart unlock so it doesn't bother me much." lol
No real issue. It's better than the LG G7 fpr I'm coming from which would consistently stop working for days.
Works better than the S20 Ultra and the S21 Ultra ultrasonic fingerprint sensor that I've used in the past.
I had a Note 20 Ultra as well and I didn't like the FP scanner on it too much but the S21 Ultra's was accurate and fast. The Pixels is super accurate, just a tad slower but it doesn't bother me at all since it works just about 100 percent of the time.
Works fine for my usage...
I've been having a good bit of issues with the fingerprint scanner and they aren't related to speed., about half of the time the Pixel 6 Pro can't read my finger print at all. I'm coming from Oneplus 7 Pro that feels light years ahead of this fingerprint scanner. I've tried all the tips and tricks people have been recommending, which has helped, but it still says can't read fingerprint 50% of the time. It's very frustrating.

Did you re-do your fingerprints after the most recent firmware update? (november)
Also did you heed the fingerprint setup instructions? (full underside first, then sides, then the tip etc). Meaning don't mindlessly hammer your finger on the screen, do what the setup tells you precisely and exactly.
The system tells you what to do - if you do that, it should work without a problem. I got my finger in the system (4x times the same one, just re-do the setup with the same finger) and it works without a problem, nowadays I am getting about ~95% success rate. Even partial ones get through, even though they might take a second or two to register, but that's okey since it's just a partial one.

Btw concerning the video that was spreading through reddit, where someone claimed that his girlfriend was able to unlock his phone, without ever having it set up - I recently found that it's possible to use two fingers when setting up one fingerprint at a time (go with one full thumb, then when it asks for the sides, use the other finger from the other person) - that probably happened here, someone tricked the system and then spread fakenews to gain a few likes/attention.

Honestly, I can't remember if I re-did after the November update. I'll clear out my fingerprints and try it again. Thanks for the tip

You're welcome.
The fingerprint setup system was changed after the firmware update, so it's basically mandatory to re-do your fingerprints if you want a higher success rate.
It's a shame that Google doesn't communicate this directly, it should be a system message suggestion right after the update.
What I'm wondering is that maybe some people ended up with a bad FP scanner? I mean it is a possibility since anything can be bad but hopefully we can get enough feedback to get closer to the bottom of this. If someone who has a bad scanner can try someone else's and see if it's still an issue that would probably help although it's not like everyone you know will have a Pixel.
My pixel 6 pro fingerprint reader works most of the time for me. The worst fingerprint reader I've ever used was the Galaxy s20 ultra. That thing didn't read my finger half the time so I just defaulted to the password.
I didnt vote, but mines works about 80 to 90 percent of the time. but it sucks when it doesnt work. It seems it happens at the worst times possible.
It's good but not as fast, accurate or convenient as my Pixel 5 with the Ringke Fusion case and convenient finger-centering sensor cutout.

Same here with the Note 10+. I still kept using it but argh.

Question Biometrics frustration

I have a new S22 and my experience is so frustrating. I am coming back to Samsung after a few generations from Huawei (mate 20 pro and P30 Pro). What I can't digest is the fingerprint and face id works so flawlessly on Huawei which is a relatively newcomer to Samsung and they have done it so perfectly. (on Mate 20 Pro it used a 3D scan and on P30 Pro 2D scan). Samsung with all its generations with many decades of experience still struggles.
The fingerprint is too slow and sometimes after a few tries. Face ID takes a while to open the screen. And what's more - when I enable fingerprint - for some reason the face ID just becomes lazy, I don't see it even attempting to detect the face (from the rim light effect on the front camera). It looks as though the fingerprint has superseded the face id. I am getting more and more frustrated by this. I did try scanning both fingerprint and face id several times. But no luck. I even suspected probably there is a way to prioritize the usage of biometrics and looked for it but there is none.
In contrast on my Huawei - it just takes a fraction of a second to unlock as though it is not scanning the id (both face and fingerprint) but actually it does the job so quickly. What is happening here - is this how Samsung had been all these years? I can't believe if they claim to say they've improved from previous generations. Why is the face id so slow and most times (well-lit environment as well - the face id is not at work at all (no rim light around the front camera, as though the id is not at work)
Is this the same experience others have and is normal for Samsung? Do you all think it is a one-off case and a reset might fix it? Please advice
I don't use face id so can't help with that, but are you using a screen protector?
I had a Spigen glass screen protector, the glass was amazing but the fingerprint didn't work 80% of the time, especially with dry fingers.
I switched to a film protector, re-did the fingerprints and now it's perfect, very easy to unlock.
