Hi,
Do you have cases when the fingerprint wont unlock the phone (until 5 failures are reached)
This happens to me every now and then and is quite annoying. I don't have a screen protector and have disabled battery optimization for biometrics. Wondering whether to bring the phone for repair.
Did you update to ATE6? If not, please do.
Also try to re-add your fingerprints again, i found that speed and quality of fp sensor depends on how "good" you scanned your fp-s.
Another trick is to press harder when scanning and unlocking (which also works).
Yes, I am on ATE6. Will renroll fp to see.
The issue that I've noticed what it could be is the scanner is always active. The problem I face is when I pull the phone out of my pocket I've reached my attempts and have to use my pin.
In the case of the other post, just add 2 of the same finger. My thumb and pointer are in it twice each

I don't have this experience with pulling out of the pocket. Added the finger again and now I am trying to train myself how to press harder and hold the finger patiently until it unlocks.
Adding same finger twice solved this problem for me, when adding second time make sure to scan your finger in different angles, almost like youre trying to miss scanner
S20 here. New tip. I think ultrasonic fingerprint reader is located slightly off-center to the left, so when adding and scanning your fingerprints, aim slightly left.
I discovered this yesterday while cleaning the screen under a bright table lamp, I noticed that you can actually see exact reader's location, where it is bonded to the screen underneath it. I assumed it's not visible.
Reader appears to be letterbox shaped, length around 1.6, width around 0.7 centimeters.
When you turn the screen on, fingerprint icon is located in the center of the screen, you can almost fit another icon next to it to the left, to represent reader's length.
Combined with other tips, some also mentioned by the users above, I rarely have to scan twice now, three times tops. Before I often ran out of allowed number of attempts and had to enter password. Still not perfect or super consistent, but much better. Soo..
Main tips:
• When adding and scanning your fingerprints, aim slightly left. Always keep reader's shape and position in mind. Turn off your screen, and examine it under bright desk lamp, to determine exact reader's shape and location.
• Register your thumb two times for each hand, while rotating your phone (slowly from portrait to landscape, back, and beyond until phone hits space between your thumb and index finger) and move thumb slightly towards finger's bend point and then towards fingertip (do it all over something soft in case you drop it while rotating).
• After you added your fingerprints, lock and unlock your phone multiple times (let's say 10 times) using each hand before you decide if doing it all over is necessary. Maybe even keep it for a day, see if phone manages to optimize data, or maybe you will get used to positioning your fingers in a certain way.
• Make sure to moisturize your hands, noticed scanner struggles with dry skin.
• You may also try to register both left and right thumbs (or other fingers) at the same time, this may speed up unlock, though not sure how secure this is.
• Don't hold your finger for too long, simply firmly tap and lift, phone should unlock.
I would try extra sensitive screen setting in display and try re register fp again.
I've heard some registering same finger twice but I don't really have any fp issues after disabling optimization of the biometrics apk

I remember having Touch Sensitivity alway set to on, believe it helped with gaming a bit, but found it had little or no effect on fingerprint reading, was constantly running out of attempts, and was forced to enter password, which is very inconvenient when you're in a public place. But I think it's still worth a try, maybe on S20's that option is somehow interconnected with fingerprint scanner, and boosts something in it as well, but I personally noticed no improvement.
Disabling battery usage optimization for "com.samsung.android.biometrics.app.setting" in "Optimise battery usage", did not improve recognition. I think you should still do it, as it can reduce occasional delay, but if you're using your phone all the time, locking and unlocking, etc, and having reader problems, this will not improve recognition. When it says no match (press harder, cover entire sensor, etc), it means software and scanner are working and reading your fingerprints, but failing to match patterns, so disabling optimization will not improve anything in this scenario. You should delete and try adding your fingerprints again.
Now, after registering same finger twice I noticed immediate improvement in recognition, and looking online for different tips of how you should hold your phone while adding fingerprints, was able to improve recognition even further.
Along with tips mentioned in my previous post, I now rarely have to go beyond two attempts.
Maybe this improvement also has to do with us instinctively learning what works and what doesn't.
Maybe this also has to do with finger size, skin (space between and width of friction ridges), and skin type (dry, oily, etc), that's why we have so many mixed reports. Also hygiene. I noticed with excessive hand washing, number of successful recognitions decreased, even with well moisturized hands.
In conclusion I'll say there is definitely room for improvement here, maybe larger more powerful ultrasonic readers are the answer, maybe better software. Because even with all the tips and tricks, it's not perfect, at least in my experience.
Oh, almost forgot, that factory screen protector has to go. Better fingerprint reading and much better picture quality without it.
And of course, make sure all the latest updates are installed, to all the people who just got their phone out of the box.
I typically enroll 4 of the same finger. I only use my right thumb and really haven't had any issues. I have the WhiteStone Dome glass installed. I have increased touch sensitivity turned on.
Using a poly screen protector with only two registered finger. Working perfectly with absolute zero issue.

Hi all,
I simply love this phone, but I'm facing a situation that my screen is too sensitive. The home screens were so sensitive a few programs were started without my knowledge. It got better after I switched to Launcher Pro.
However, it is still too sensitive in other areas. When I'm scrolling down, say, the apps in Market, I'll always end up selecting a few items accidentally before I reach the end of the list.
I've used HTC Desire in the past and I'm quite sure the problem is not due to me.
Does anyone else face the same problem, or I have a hardware problem? Or software problem? Can I be tweaked by any means?
Any feedback would be useful! Thanks!!!

I faced this problem before... while swiping, apps accidentally open. But instead of "too sensitive" i thought it's insensitive... because a short swipe was sometimes interpreted as a tap (maybe because the swipe was not fully detected?).
Anyway, I had 2 layers on my device... the pre-applied sheet and another screen protector that came with the box.
I removed the second layer, leaving only the pre-applied sheet, and all is well again... no more accidental "taps"

I'm having the same problem. And that solution seems to make sense. I would give it a try, but if the problem still occurs, I'd be wasting one screen protector..

That was how I solved my problem. I actually put on the spare screen protector because when I got the set I didn't realize there was already a pre-applied layer.
Don't blame me if it doesn't work for you
perhaps some of you guys just have the shakes?! ;-p
I guess the screen is never to perfect for everyone.
kargtan, I've noticed the same about the tap sensitivity - I often accidentally "tap" when I mean to swipe. Came from an iPhone 3g and didn't notice this on that device. Might be a matter of getting used to it, not sure. Have you gotten any feedback from others in other forums?
I've noticed this too, and put it down to the screen protector. It's not android OS causing it, never had the problem on my htc hero...
However, now that i've gotten used to the phone it doesnt do it any more - guess my brain has automatically trained itself to drag the screen a little bit more firmly or something.
One thing i have noticed about the arc is: because the bezel around the screen is so thin, i often accidentally launch apps just by holding it. My fingers wrap around slightly & touch the edges of the screen.
Does any of you have problems while trying to swap a screen from another and instead of swapping you get like a "bounce" and stay on the same screen? because that happens to me all the time, I came from an htc Legend and this is making me crazy !
btw, this happens to me if I hold the phone with my right hand and try to do the swapping with my thumb, the only way to get it right is to hold the phone with my left hand and use the index of my right hand
Screen too/not sensitive
Hi guys,
I think the problem arises from the slowness of the phone, not "too sensitive". I used to use the HTC Desire in the past and I was very used to the screen scrolling very quickly. In contrast, the arc is slower and hence the screens don't scroll as fast and hence my way of handling the Desire would cause the problems stated.
I did a few things since my last posting and it seems better now:
Replace the SE Home with Launcher Pro - this seems to have improved on the speed of the phone, and hence better responsiveness to the touch.
Rooted the phone and uninstalled some stock programs.
Removed useless widgets on the desktops.
Adjusted my way of scrolling as someone has suggested.
This is quite frustrating at times, especially so because other than this problem, this phone is a gem, especially its form factor, the sound quality and most importantly, the quality of the camera.
I might sell the phone once the company issues me with a Blackberry (DANG!), but I am kinda unwilling because I have been taking lots of photos with my Android phones and these photos are generally well-liked by my Facebook friends.
agree with bezel thing and hard to use thumb.
noticed arc screen (the screen guard perhaps ) easily get oily and slippery.
had to wipe phone and wash hand so often that make me like some sort of disorder.
Don't know why you guys seem to be having problems... I don't have any issues with my screen swipes at all... smooth and fast.. both on stock and Launcher Pro..
Same deal here. But that's because the screen is sensitive beyond the display area including the black border, and the edge is too narrow. When I use one hand swiping or tapping, the palm of my hand touches the black border. The screen registers two touches in quick succession and thus jumps.
In Phone keypad, enter *#*#7378423#*#* (the numbers mean SERVICE word in keypad), you can go into test mode. Select [Service test]->[Touch Screen] to test the badly touch screen of SE Phones.
You will discover when you swipe the edge of touch screen, the touched result is very not satisfied. The lines you swiped will not accurate and appear like jags, or stick on the edge of the screen.
The touch panel made in China...? ;-)
Me too!
Hey!
i also have a xperia tipo....and i too have the sensitive problem
Could also be a kernel problem?
I remember I installed a kernel a while back that would make my screen hypersensitive; just hovering over the screen would already activate it!
I don't remember which one, it was back in the GB days. But I'm pretty sure it can be changed in the kernel.
Forget all the "you need to not press hard" bull****, it's way simpler than that.
Register your finger while holding the phone in one hand, position your fingerprint on the sensor exactly as you would casually, keep registering it that way, from a limited position on a one handed held.
If you do a "proper" registering process of your fingers from artificial positions just because you think it helps the sensor, it won't work, even minimal changes in your finger shape will make it generate different keys that will not match a real life press.
I registered my fingers from positions I would practically use to unlock later on, the success rate is now 100% as long as I don't miss the sensor on dark screen, no matter the pressure or the time you hold your finger on the sensor, it will now work every single time

I tend to agree with you. I registered both right and left thumbs and they both work on command. No 2nd or 3rd attempts yet. Just register the thumbs like you would naturally hold them on the screen(flat).
I also feel like the fingerprint scanner icon is a bit misleading, given the fact that the sensorbis actually above the actual icon

But when I try to casually tap the screen to register fingerprint naturally, it won't register, keeps saying press harder or hold longer
Or register the same finger twice.. That's the better solution

The tap needs a certain amount of pressure, not too light either

Same, and i registered the finger I'm going to be using most twice. Registered casually and from a natural position. I think mine has failed to unlock maybe 3 times in a week. In this case...keep it simple don't over think it.
Sensor is off
I noticed when the screen is off in dark mode and u take a flashlight on a angle of the screen i noticed the sensor is like a U shape just slighty to the left of the finger print icon, now that i kinda setup my finger print just a tat left og the finger print icon its been 100 procent i also noticed moist fingers work better . i could be wrong about it being a sensor but the U shape i think would be the sensor

You don't need to move your finger away, the sensing part of the sensor is perfectly aligned in the middle
New update on firmware.Science for snapdragon. SBA TO SD3. Made a world of difference for me. Can't wait for my replacement Whitestone to get here to see if sensor works any better with tempered glass. This update absolutely made a huge difference. Not slightly, very significant change for me. I register both thumbs twice and I couldn't get it to not unlock every time. 50+ unlocks and maybe 2 failures. I stopped counting at 50.
Will it work on verizon or only unlocked?

I'm waiting on my Whitestone replacement as well. Can you keep us informed on how the sensor works with your new install? I had to pull the last one. It was horrible. I miss my glass...
The problem for me and many people is that when the finger being scanned is dry, scanning won't work (and will be asked to "press harder"). Some people then try to press really hard and it will, forever, say "not match".
People with moisted fingers will not have this problem and will not understand the kind of people I mentioned above. Since I have S10+ for a month, I, kind of, know when the scanning will not work. I will use face scanning instead or if I really want to scan my finger with whatever reason, I just rub my nose with my thumb then it will 100% work (greasy nose does the trick).
I don't know if Samsung can ever fix this since it is not how accurate the reader is.
Dry fingers don't work with the fps even when removing the pre-installed screen protector?
I am debating to remove the screen protector and my main points are:
1. The protection offered by the pre installed screen protector is minimal either way.
2. That the screen colors and usage will become much better.
3. That the fps will work much better even with dry fingers due to the oleophovic coat of the screen.
Has anyone who removed the screen protector tested this?

I removed mine yesterday and it does help a little with the fps. I still don't like the fps though, I would much rather have a Face ID equivalent. Or have the fps on the back.

I had reached out to Whitestone because my first install failed. I had the WSD on my s9+ and went through 5 or 6 in the year (I dropped my phone a lot). So I knew what I was doing, but the first try had a huge bubble. Tried doing the cleaning and reinstall with the backup glue and had a bunch of microscopic bubbles in the top and bottom (guessing I didn't clean it well enough before reinstall). I wasn't sure how to register warrenty wise because technically it worked fine, just was having FPS issues. They ended up replacing without me paying for the shipping which was awesome of them.
Recieved my replacement today, and the install is flawless. One thing to note is on the 10+ the absorb pads hook into the top tray not the bottom (that was a hell of a mess the first time). The original kit didn't come with the pads pre-installed like the replacement kit.
I haven't even gotten the latest OTA yet, and with the WSD glass, it's just as quick and success rate is the same as when I had the pre-installed protector. Might even be faster than my s9+ was...
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.
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.

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...

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
I'm new to in-screen fingerprint scanners. I've had this S20 for less than one week and miss the back of the phone scanner of my previous phone. Maybe in time I'll be able to reliably find the scanner without looking at the screen. Do long time users of this sensor eventually develop muscle memory to reliably find the it?
I've found a flawed, low tech method to unlock the phone without looking at the screen. I put a small piece of clear tape on the screen centered on the fingerprint scanner, see attached photo.
After finding the tape with my thumb I need to lift my thumb and put it right back down. I was having a high rate of success unlocking the screen this way. Unfortunately putting the phone in my pocket rubbed off the tape. I cleaned the screen protector (factory installed one) and reapplied the tape but it still came off in my pocket.
Just having the tape there for about 30 minutes of unlocking seemed to help train my thumb. Even after losing the tape I had about a 60% success rate in unlocking the screen without looking at it. I wouldn't call 60% acceptable but it's better than I was achieving before.
Maybe someone has a suggestion for a better method? Better tape? A small drop of super glue or some other adhesive? Maybe use this tape method short term to train my thumb to find the sensor? Something else? Maybe someone will eventually develop a screen protector with a subtle dimple or divot.
