I've had my Note9 (Tmo) since release, so about 2 weeks now. Usually a quick tap of my finger on the fingerprint scanner and the phone immediately jumps to life and I'm on the home screen. But today it's acting erratically. Now it takes like 5 or 6 presses for it to register, and that's only after I turn the phone on first (it won't skip sleep and go directly to the home screen anymore).
I tried a rebooting, recreating my prints, as well as making sure the scanner is wiped perfectly clean, and that worked... But only for a little while, the issue has come right back.
Anyone else seeing similar issues?
Do other sensors work as expected?
On my previous Note8, when sensors stop working due to hardware fault, the fingerprints also did not work.
BTW I have not experienced the same issue on my Note9 yet.
Are you using a theme? If so that could be the issue. Uninstall theme and try fingerprint again.
Wash your hands.
I also have this issue, it's pretty annoying. On the lockscreen, the phone says "fingerprint-sensor not responding, try again later", and that's it. Tried wiping cache from the recovery menu, nothing.
Try typing *#0*# into the dialer and go to sensors test, should be able to determine if your finger print reader is faulty or not there.
Try cleaning the fingerprint scanner or using a wet wipe on your finger. As the lack of moisture is probably what is causing this issue. It happened to me a few times in HK.
I have the same issue.
My scanner is now telling my "fingerprint wet." But my fingers aren't wet, and I wiped the scanner down several times. Like the OP says, it works for 1 or 2 swipes, then won't recognize my fingerprint.
I'm having the same issue with my Note9. In my case, the problem happens ONLY if I had my phone in my pocket more than 1 minute, the fingerprint sensor just won't work, it's not like it doesn't recognize it, it's dead. I have to wait about 10 seconds putting my finger on the sensor 'til it works. I have tried everything. I'm pretty sure it's something in the software related to the phone being in my pocket (not because the phone's been idle), because when I go to bed and put my phone on the table, the next morning I just grab my phone and immediately the fingerprint sensor takes me to my home screen, no problem.

Do you guys have solution to this I been having this issue for a month or so now and i think it is getting worse.
Hi guys, be brave and call Samsung. The phone is under warranty.
They will collect it and drop it off for free, after repairing it and putting your phone back to water and dust resistant.
It took me about 10 days all together, if not less.

I've had samsung repair experienced before my Galaxy s8+ it took them about 5 business days turn around repair it was just software issue.. But with this fingerprint if it's just software glitch or setting i rather do that first but if not I might have do warranty claim.. it always take 2-3 tap for me to work on the fingerprint this is way way slower than my S9+.. Did you have fingerprint issue?
It is definitely not software. Days i have spent uninstalling apps and themes and testing and then resettimg it all and so on and so forth!
It seemed at the beginning that a factory reset is enough, but next day it would start again.
It finally gave up and i have called Samsung, as i do not buy insurrance for my phones and they sorted me out.
I knew it was not software when i have booted the Note into safe mode and it behaved just the same.

Sorry, forgot to quote you in my reply above.
Anyway, now after the repair, the Note responds diferently, it unlocks fast as hell using the fingerprint.
Try erasing all your fingerprints and re-registering them all over again. As sometimes your fingerprint settings maybe corrupted by a OS update.

Mine isn't like that. Fingerprint sensor works once the device is already in use but once in sleep mode for awhile it will take 2-3 taps for it to unlock and it doesnt happen all the time so My issue is sensor sensitivity and it seems to me that the sensor is not getting any power once in sleep mode to save battery that's why it is less sensitive that's just my opinion. But I already made a ticket to samsung and unfortunately the repair center which I dont trust at all the uBreakifix do not have the sensor in stock. So I may have to call in to ship out my phone.

I have already re-register my finger about 20 times but seems to happen over and over.

i am and i wish i knew how to fix it
*#0*# sensor test says that the RESET test has failed. I'm getting random reboots while not using the device.

The test shows RESET: Failed. Everything else is a PASS. It must be a hardware problem. I am getting random reboots while on standby when the fingerprint sensor is turned on.
(solved: Decided to keep the post instead of deleting it in case someone else faces the same issue. So it was just broken scanners. Got a good one and it worked perfectly. So far no heating issue. So point is the over heating could only mean its a broken scanner and not a main board short or anything.)
So I got a used g6 with a broken screen and non working fingerprint scanner. Switched out the scanner but it gets extremely hot
and doesn't function. I'm wondering if the replacement scanner is broken or if something is wrong with the main board.
There is no other problems with the phone.
Also, I'm wondering how does android 8 handle hardware changes. Because when it was factory reset, it had the old
broken finger print sensor on it. So does android just ignore activating finger print scanner related files when its installed since it didn't detect the scanner? or
is the OS supposed to recognize the replacement scanner and make it work without any extra steps? Is there any way to tell the OS to look for hardware changes and install
needed system files? I'm looking for any expert help with this if you have clear idea what's going on. Thanks.
Day 3 with my S10+ and after two days where the fingerprint sensor worked "reasonably well", today it refused to unlock, no matter in which angle, which one of my 3 registered fingers and no matter how much pressure (or almost no pressure) I applied. Only device restart solved the problem.
And yes, I have all the latest updates (at least the Day One that tmobile released...)
Is anyone else experiencing the same?

Mine is acting up as well. When I first got it, it worked great and now I can barely get it to unlock
Edit: forgot to say my wife is also having troubles with fingerprint as well

Same here. My Note 9 fingerprint reader was far superior. Has anyone tried removing the pre-installed screen protector? I wonder if it would help. I may try it and/or return the phone for a different model. Frustrating

Also, have you gotten the FP reader update yet? I know unlocked AT&T models got it last night. Definitely helps.
mine working fine stock screen protector all updates done. received @6 March and its exynos indian variant S10+ G975F
Sent from my SM-G975F
Working fine here. Have exynos version. It initially didn't work for one of my thumb. I deleted it and again register it using every angle. Its working fine after that. Maybe Samsung released it too early without testing much.

Received my galaxy s10 on March 6th. I was super excited but my excitement fizzled down after testing fingerprint scanner. That thing just would not work. It worked like 20 percent of the time. Some times I would try 5 times in a row and it would fall all the time. I had registered two thumbs twice but that didn't help. I went through a lot of threads on XDA and other forums and gathered all the suggestions. Figured out some of the things that worked for me.
Here is what you need to do to make it at least 80-90 percent reliable.
1. Upgrade to ASBA version of the firmware. I am not sure which region you are from but Samsung just released a firmware update which was about 440 MB. This should already help a ton.
2. After you upgrade, go to settings and search for "touch sensitivity". Go to the setting and turn it on. This will increase touch sensitivity of the display. It may use a bit more battery but I have not noticed any difference.
3. Now remove all your fingerprints. Click add finger. This time, when scanning finger do following.
A. Start with the middle of your thumb. Not the edge of the thumb. The part that is about half cm inside. Press that portion and don't do much of a sideway motion till you reach about 80 percent. Now use the edge of the thumb and try to move the edge a bit to reach 100 percent.
B. Add the same finger again. This time start with edge and try to get to 80 percent without much motion. Then use middle of thumb to reach 100 percent.
C. Do the same for other thumb. Also don't register your thumb in vertical position. Just register the way you would hold a phone and try to scan your thumb. Close to horizontal may be at 5-10 degree.
You may be required to press a bit hard while registering your finger but this is not needed to unlock the phone.
3. Now turn off the screen and try to unlock the device without turning on the screen. I know it is a bit hard. Just go with the feeling and press gently with middle of the thumb where you think the scanner is. Note that this is not capacitive scanner that you just touch and done. Put your thumb with a gentle press and leave it there for may be 1 second.
4. Screen should come on and phone should unlock. If it didn't work then turn off the screen and then tap it once to start always on display. This will show you the scanner on screen. Just gently press and hold for 1 second.
I have noticed that the scanner does not work when the finger is super dry. But I think after the update it has gotten better. I had initiated a return for this device and was planning to just get an iPhone. But after the upgrade I decided to keep it and trade in my galaxy note 8.
This is really worrying me. I don't want the gimmick / novelty instead of reliability
Mine is perfect. Installed the update and removed the screen protector it came with and fitted an aftermarket one my local phone shop sold. I get a failed attempt maybe 2 times a day because I haven't had my finger on the right spot
Initially I had the same issue , things I have done which resolved the issue
1 Most important, update the software version. Recent version has fingerprint issue fix.
2 Enable touch sensitivity from settings
3 Add same finger twice , i prefer to add my thumb finger in horizontal position same way you hold your phone
The only trick people miss out is they do not cover the entire sensor while unlocking...just a small adjustment and the fps is as fast and reliable as any in the market.
I initially had his problem trying with part of the sensor covered and i thought it was horrible.
Infact if you cover the sensor wholly you dont need the touch sensitivity turned on as well. I have it mine switched off.

Another tip that worked for me is...while registering the fingerprint, hold the phone as you would while you unlock the device and scan the same position of the finger with minimal movement until it flashes 80%.

I took that crappy screen protector off the second it came out of the box. Only had it 24 hours and it's working so far, but time will tell...
Fingerprint sensor gone
Hi, I'm new here
After I restore factory default of my S10, because it was consuming battery too fast, the fingerprint sensor stop work.
At the samsung's members app I did the interactive check of the sensor and said it is ok.
The phone and apps are update.
I try everything to restore the sensor but had no success. Does anybody knows what could be, and if it is a software problem and how to restore?
Thank you
My mom was trying to register her fingerprint on my Mi9 but it was a very difficult task since the scanner couldn't detect her fingerprint. After a long time and being able to register the fingerprint, now it's near impossible for the phone to scan her fingerprint and unlock the phone. Meanwhile, my fingerprint unlocks easily almost every time, so I really don't know what's happening and how can I fix this. I'm using MIUI 10.2.26.0 EEA. I wanted to put the global beta to try, but since they won't update anymore global betas I stayed with the global EEA.
She's looking for a similar phone, but if on-screen fingerprint scanners have a problem with her fingerprint, she will have to stay with standard fingerprint scanners that she never had a problem with.
I'm currently using a screen protector, but since it works great with my fingers, I don't think that's the problem.
Are there any tips on fixing this problem or at least make it better, like finger positions or doing something with the finger before scanning, without having to change ROMs?
If it works ok with your fingers, "probably" not a sensor or rom problem.
I always register same finger twice for better reading, but if your mom's fingerprint is washed out, will never be 100% efective.
Hey everyone,
This is my first time using a phone with an onscreen fingerprint reader and when I first got it I was somewhat disappointed with the speed of reading. That being said I tried a few things out and managed to get the reader to be fast enough for my liking so I thought I'd share what I did.
Note that this is not in any way meant to be a comprehensive guide that works for everyone-- just what I found worked best for me.
What I initially tried to do was register five fingerprints using my thumbs and index fingers. I had two registered for each thumb and one for my index finger. This worked but was markedly slow no matter how many times I redid the scans.
I then tried to delete all of them and then only had 1 fingerprint saved but scanned both my thumbs in the same fingerprint. This worked MUCH faster for reading but often didn't recognize my finger.
The sweet spot was when I added a second and third profile ALSO using both thumbs. I noticed by the third profile that when i tried to put my thumb on to teach it it would say "fingerprint already enrolled" more and more often untill it was a struggle for it to recognize any angle of my thumbs as "new". Once that was done I found the fingerprint reader to be incredibly fast and accurate.
Tldr; to get the best speeds add three profiles using the same two thumbs in each profile until it stops recognizing your thumbs as new fingerprints.

If you can register the same print twice then it didn't do a good job the first time. I have never been able to register the same finger twice.
Not sure what's going on with your phone where you need to do all that.
I registered both thumbs and index fingers only once each. It's basically the same speed as any physical fingerprint reader I've used with any of my registered fingerprints.
Seems to me (in my experience anyway) the only way to make it go faster is turn off all security and pick up and use the phone!
It's not as fast as the dedicated reader on the back of the 6, but it's plenty fast enough
I have registered each of both my thumbs only once and it works 99% of the time very quicky. Something is wrong with your finger mate.
I can confirm that registering two sets of Prints with the same finger works......and the fingerprint reader is way faster now. it will tell you that you already registered that singer but the trick is to keep trying because it didn't register every part of your finger with the first fingerprint.... my fingerprint reader was pretty fast before but now it's super fast I barely have to touch it. I can confirm this definitely works... Also I could only do two profiles for each finger
I needed to do this on my 6T. 7 Pro has been as fast as a physical scanner so I haven't felt the need to do any of this. Normal registration and use of the scanner works flawlessly for me. Just my experience!

Same. I only registered my left and right once. Fingerprint sensor works 99 percent of the time and fast as hell. I had a note 8 and the fingerprint sensor on those was slow as hell.
Try turning off the fingerprint animation as well. It made it faster for me
You suck guys. You suck.

That's actually entirely possible ?
I work in health care so I have to sanitize my hands easily 50 times a day.. that tends to wear out fingerprints!
I turned off the haptic feedback.

Hahahaha the ole stink finger
Guess I've got pretty complicated fingers as the thread starter as well ?
What works for me is:
1. Register the right thumb (1. fingerprint) with the "base" of the finger and a little bit more pressure.
2. Register the right thumb again (2. fingerprint) with the tip of the finger and light pressure.
3. Register left thumb like before (3. + 4. fingerprint).
4. Register index finger "normal" (5. fingerprint) or anything else.
5. Change animation to stripe.
When unlocking the phone from ambient display, lay down your finger while increasing pressure a tiny bit. It's super fast for me now.
I've got no chance when registrating only one or registrating the fingerprints in dark rooms, it'll be fast for the first hours but then they'll become very slow.
Maybe this will help anyone.
