Fingerprint Scanner Issues - Sprint Samsung Galaxy S6

My phone's fingerprint scanner worked great for about a week, now it's jacked. I've had to resort to pin security unfortunately. The fingerprint security scanner was one feature I REALLY liked about the device. Now, I can sit there and watch it scan in its own prints. There's another thread on the subject here in the main galaxy s6 forum:
http://forum.xda-developers.com/galaxy-s6/help/fingerprint-scanner-t3080516
You can see my post and issues as well as others there. Guess I'll be making a trip to Sprint. I'd almost rather stick a hot poker in my eye

Finger Print Sensor Problems Anyone?

Hello, fellow Nokia fans,
I have been using the Nokia 6.1 as my daily phone for the past 2 months, and it has all been a great phone except for the fact that the fingerprint sensor on this phone sucks a lot. Every time I try to unlock my phone using my index fingers it says something like partial fingerprint detected, try again.
It gets really frustrating at this point, the phone that I used prior to this was a Galaxy S6 which had a front facing fingerprint sensor, that made things much easier. Am I doing something wrong? Is the same issue bothering anyone else? Kindly help me in mitigating this problem.
TIA, Peace.
You can calibrate the same finger twice for more information for the sensor so it registers it more accurately.
I registered my fingerprint like I would register my fingerprint by habit. Now it works perfectly, and I have no complaints whatsoever.
Those in the US using fingerprints to unlock your phone (any device) be aware federal courts have ruled you CAN be compelled to unlock your phone with your fingerprint. You CANNOT be compelled to give up a password. The difference is something you are vs. something you know. Sure it is a pain to use a password/PIN, but think of all the personal information you carry with you in your phone.

you also have problem with fingerprint before you do register again? mine is only working when putting fingertip at center, unlike other phones like xiaomi that unlock fast and easy with any part of finger touching the sensor, I don't know if its the sensor smaller or it require more accurate scanning than other phones, it works but sometime hard to unlock when in rush or when finger is sweaty
In fact, this is the worst fingerprint sensor i have tried.
I have Nexus 6P, Huawei Mate 10 Pro and P10 with me
Nokia 6.1 fingerprint sensor keep showing partial detected when hand sweat, dirty or even normal case

Yeah, buddy even I fell the same thing, but someone suggested, registering the same fingerprint sensor slightly helps with the issue.

Yup, this does help out slightly
I did register 3 type of single finger, but still unrecognized in some case
Even the slightest amout of sweat and the fingerprint sensor fails. Thus I had to set up trusted face to make the unlocking process less painful. Unlocking this phone using the fingerprint is pain in the ass. I think the sensor area is too small that it fails to detect the parts of our fingerprints or it's not calibrated well.
I don' t mean to sound overly negative but the fingerprint sensor is next to useless unless you hands are completely dry and not sweaty whatsoever. The success rate is so low for me that I don't use fingerprint sensor on the 6.1 and went back to using a password - which is at least works consistently
i am using nokia 6.1 plus from past 1 year. the fingerprint sensor also works properly but the option of adding fingerprint suddenly gone right after updating the security update.. how to get it back? please help...

I have it under settings>security>fingerprint can you post a screenshot fir the same?

Biometrics are really poor?

Hopefully I am not the only one with these issues. I am coming from an old Huawei device, Faceunlock was instant, if it got the slightest view of your face it unlocked, On this you have to hold it up right in front on you which makes you look like a **** and even then it sits spinning, there is a good second or so delay.
The onto finger print again another disaster, very slow and sometimes just doesn't work. I've registered several fingerprints but doesn't make much difference.
The easiest option seems to be using the swipe unlock code method. Disappointed with this.
Anyone else having these issues.

Face unlock is good for me, it detects even from a far distance. Try registering your face again.
Fingerprint after may update has been improved but still not the best.
Add your fingerprint by pressing the same area of your finger continuously, (move it a little if it says "please move your finger or whatever" and then start adding the same part again) don't add the edges of your finger, I've noticed that adding edges/corners of your finger makes it slower to detect.
Yeah, this phone optical finger print is crap, the worst among other optical finger print phone. I guessed samsung enginer sniffing glue when design this phone
I haven't used the facial recognition, but the fingerprint scanner is pretty bad. I'm coming from an LG G6 and the G6 was miles better. I am hoping this is something that can be addressed in a software update, but I'm not so sure about that. Might just be ****ty hardware.

strange problem with fingerprint scanner

so I have my A70 for two weeks now and I am happy with it. the fingerprint scanner is okay, not as fast as the physical one but I do not mind. my security update version is 1 may 2019.
so yesterday I noticed that, at work when I take my phone out of my overall chest pocket I find it unlocked and many apps open. it did this consistently throughout the day. after a lot of experiments and investigation I figured out that fingerprint scanner reads the fabric of the overall as my fingerprint and unlocks the phone!! just the slightest touch of the fabric to the sensor and it opens immediately. so I went to fingerprints setting and through (check added fingerprints) I figured out what fingerprint the sensor was recognizing and I deleted it, but the fabric was recognized again and again until I deleted all of the added fingerprints.
when I went home I enrolled my fingerprints again and tested it on the fabric many many times and other types of fabrics also and it did not unlock, so I thought that solved the problem, but today at work the same thing happened again!!
I am really disappointed in the fingerprint scanner now, I really like the phone but I do not want to go back to PIN unlock.
so, what is going on?!
note: I work in an office and I had the phone for two weeks without problem and I always put it in my chest pocket, but yesterday and today we had site visit and it is hot here and I got really sweaty. may be the sweat is causing the problem?
Be it sweat or anything else, this shouldn't happen. Take your device to the nearest Samsung customer service center and tell them to have a mechanical check on the device.

I had this problem when I was on the older version. Issue went away after software update

Can't stand the in screen fingerprint reader

If I have one beef with the Note 10+ its the Fingerprint reader. Can't stand it. Half the time it doesn't register and having to push on the screen in the exact location is a pain. On the Note 9 and even the Note 8 it was so simple. You just moved your finger on the sensor. I've gone to using the face scanner because I can't stand the fingerprint reader and I know that isn't even secure.

I'm having little trouble with it. Try rescanning your fingerprint, and make sure you get plenty of variety in the position of your finger during the scans. If your haven't applied the Aug 1 security level patch, I think that helps.
Try registering the same finger several times.
Only trouble I have is just getting the right spot, as days go on I get better at putting my finger in the right spot.
I hated the Note 9 because I had to pick my phone up constantly to unlock it or put my pin in. Since I have apps for work that unlock via fingerprint, I had to pick my phone up just to open them.

Fingerprint reader situation - now?

Hello!
I’m currently using iP6S+ which has og fingerprint reader in the home button. I’m considering switching to A70 mainly because of bigger and nicer screen but I’m really afraid of fingerprint reader used in A70. While mine works perfectly with over 90-95% successful unlocks I’ve read and watched many opinions that said that reader used in A70 is really bad and requires to try multiple times or even use a passcode. There were updates to partially fix this issue but did they really help? What’s the situation with this reader in 2020?

I have no problems with under glass fingerprint sensor on A70 - it even works perfectly with a tempered glass screen protector fitted (which is not true for the S10!)
Once you set up the fingerprints correctly in the first place and get used to positioning your finger in the right spot, it should work almost every time. At least it does on mine. The fingerprint area could be bigger but I'm used to it just fine by now.
