Hi,
I am using fingerprint to lock my device. The device was on the desk when my palm accidentally brushed the sensor and the device unlocked. I thought this was a one time issue but I am able to recreate the scenario with any finger or palm. I even asked my friend to test it out and it unlocked. All it required was just tapping the sensor and lifting immediately.
This is really concerning. Is anyone else having the same issue?
I am on stock ROM and unlocked bootloader.

i just tested mine .. its working good.. ! maybe try registering Fingerprints again !!
Registering the fingerprints again did not work. But a factory reset sure did. Hoping to not face this again.
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
Got the phone few days ago. Most of the time, fingerprint works on first or second attempts. But now and then it takes 4-5 attempts. and on two occasions i had to try 8-9 times to get it to work. Is it a problem only i am facing or its a common problem? i already updated phone after buying. should i get it replaced or it will be ok with next update
Thanks.
common problem i think. not as fast as the previous one on N9
Well, it is not widespread or "common", some users complain about this, but this issue has been discussed at lenght since the first days of this device, do a search, you will find some useful tips, My sensor is very fast and accurate, I think it depends on several factors, temp, moisture, the way you registered the fingers, screen protectors, etc
Also, register the same finger multiple times... I believe you can add 5 fingerprints....
I understand what you are talking about. I was so frustrated with the phone when I first got it. I deleted all my finger prints and then set them up again. Make sure to slowly follow the fingerprint instructions when adding. I added multiple fingers and some more than once. I have not had any issues since. I have also read some people say remove the factory screen protector. I still have mine on with no issues. Good luck!

did you have the same issue as mine? like u had to make several attempts and sometimes even 8-9 times to make it work?
only time I've had problems with mine is when my hands have been extremely dry, putting slight moisture on my finger can make it scan better, but for the most part it works perfect unless I'm somewhere hot and dry.
I have similar issues when I have a screen protector on the phone. Sometimes I have to press multiple times, sometimes I have to press harder. Finally going without anything on the screen and the sensor works like a charm.
Screen touch sensitivity.
On my Note 10+ 5G (SM-N976U) I have a setting on the Display page (scroll down near the bottom) that increases touch sensitivity specifically for use with screen protectors. The screen itself is Gorilla Glass 6, which is twice as strong as Gorilla Glass 5, so, if you are the careful sort, you can get by without a glass protector. Even with an extra curved glass protector, with touch sensitivity turned up, I can use light gloves & still the capacitance works fine.
Touch sensitivity has nothing to do with the fingerprint sensor.
Mine works perfect with screen protector. Sure if you put new screen peotector, it takes time to recognise finger. But when protector sits perfect than no prob at all.

Mine drives me mad , adding finger prints mostly does not work , i cant record my thumb print at all , was wondering if the sensor is not correct under the screen ,its always hit or miss on my phone , with my wifes note 10 there are no problems

A hard reset solved the problem , it was not a complaint post i made but a comment on the fingerprint sensor, now fixed
I'm missing the iris scanner from the note 9.
Might send it back and go back to the 9

the sensor works well as long as you don't have dry hands, lick your finger/thumb and it will work every time, sad but true. it's something I realise after it working flawlessly while drinking in a beer garden with condensed glasses but the rest of the time it was hit and miss. seems if your skin is too dry it doesn't read well, but add a bit moisture and it works perfectly. guess it has something to do with the technology in the new sensor using vibration instead of imaging.

Yes, lick your finger everytime you want it to work in the midst of a pandemic that seems to be spread by the virus getting transmitted from the hands to the face everytime you touch it...

No need to lick fingers now...
Excellent advice from ultramag69, this mostly solved my problem, but I'm not happy with Samsung, This problem should not happen on such an expensive device from a famous brand

The other advice I've found is to set up multiple finger prints with the same finger (you can usually set 5 fingerprints). This will improve the hit rate of the fingerprint sensor...

Yes it's maximum 4 on this device, it helps a little also
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.
Hi, I'm owner of Redmi Note 8 Pro from almost 2 years now. Its a very elegant device. But I'm annoyed of its fingerprint sensor specially in summer. With mildest of sweat on my fingers, it's fingerprint sensor doesn't recognise the finger to unlock phone. Multiple attempts I have to make. How many of you are suffering from this annoyance?
Of course a sweaty sensor and a sweaty hands won't team up together. It's not just your device.
I have been using fingerprint phones from last 5 years. Huawei phones didn't cause this much annoyance with sweaty finger as this phone is causing. Finger is slightest sweaty and it won't work, I'll have to wipe the sensor with cloth and then it unlocks.

I know that Tecno phones can unlock with a very small part of the fingerprint. My friend had one. Doesn't that feel a bit not totally secure?
I'm using a phone with an in-display fingerprint, it won't unlock unless the sensor is completely covered.
I remember Galaxy S Duos used to unlock using a picture for face unlock. It wasn't perfect.
Phones enhance security every year. Apologies, I don't see your post a reason to reduce security level of FP scanners.
I wasn't talking about any other person's finger for unlocking the phone. That would be totally unsecured. I'm talking about my own finger not being recognised by the fingerprint sensor even being slightest sweaty.
