Fingerprint trace left on screen, right before unlocking - Samsung Galaxy S10 Questions & Answers

So I've been using my S10 Plus for 3 days now, and love it. The fingerprint sensor works well.. about 95% accuracy, which is fine for me.
One thing I noticed is that if on the lockscreen, there is a trace (almost like a footprint of your fingerprint that appears on the finger print sensor, right after you press it. You'll notice it during the animation where the s10 plus transitions from your lockscreen to your homescreen.
I wonder why this is happening. Is anyone else noticing it. It's very faint. But if you change the direction of your finger you might notice it more. Also, I dont' think it'll show on black lockscreens. There needs to be some color there.
Is this something wrong with my sensor, or is it just something with new technology.
Take a look at the video where you can see this better. You might have to slow down the video or just pause it.
I don't think it's something wrong with the reader, but it kind of annoys now, and now I can't unsee it lol. https://www.youtube.com/watch?time_continue=19&v=w_6e8_PHCIE

I have it too, but doesnt really bother me that much as it goes away right after it verified my fingerprints.

Okay, so it's not just me... Do you think it's just new technology kinks that need to be worked out?
I wonder if they can fix it with a patch. Anybody else notice this?

What makes you guys think it's a glitch, seems intentional to me, easier to tell where your tapping

It's an imprint of how much of your thumb surface was used to scan your fingerprint. People that are having fps issues can see that if you press it hard enough to cover the whole scanner the phone unlocks everytime. I had fps issues until I got att update about 500mb. With whitestone screen protector it's working as advertised. Just rescan your fps when you get the update and it's very accurate. As long as you press hard enough to make a big imprint of your thumb on the scanner.

To anyone who thinks the fingerprint scanner is bad / inaccurate

Hello.
I see peoples around on the internet (here on XDA to) that are complaining about the fingerprint scanner on the Galaxy Note 4 to be bad and inaccurate. Well, i'm here to tell you that it's not the fingerprint scanner on the Galaxy Note 4 that is bad or inaccurate, but it's your way of setting the fingerprint scanner up that is the problem.
I have set up my fingerprint scanner up correctly and it works extremely good. Just follow this guide and you will be all fine. This video is not made by me by the way and even if this shows the setup process for the Samsung Galaxy Tab S tablets, it still works the same for the Galaxy Note 4.
I also added a poll about the fingerprint scanner in the post here. ONLY answer it after you have correctly set up the fingerprint scanner according to the guide in the YouTube video and after you have given the fingerprint scanner some tries, thanks.
Have a good day.
Hmm well I have watched your video but I think you missed out what is causing the unsatisfactory experience.
If you are unlocking the phone supported/two-handed, such as in the video, phone placed on a stationary platform such as a table and you swipe your finger; or your left hand holding the phone while your right hand swipes the scanner - it isn't exactly a convenient feature. If you are unlocking the phone 2-handed, there isn't a lot of difference from unlocking using PIN.
2-handed unlock is 99.9% accurate for me - same as the iPhone 6/6+'s one-touch scanner. However, unlocking one handed is another matter. The phone will prompt you for a second set of 10 swipes after you done your first 10 - and if you did your second set of 10 supported on table or with your other hand, then you are likely to face issues unlocking single handed.
This is because the con of a swipe censor is that it is less accurate vs the one-touch version, and the drag of your finger/thumb while swiping distorts your fingerprint (because your flesh drags and there is pressure) according to the direction you swipe. The way you swipe 2 handed will be different from the way you swipe single handed.
I have no problems registering the first set of 10 with the conventional thumb downwards swipe. That is easy. But during the second set of 10 where I try to register one handed with my thumb swiping on its sides, there is a few hit and misses. I have eventually gotten used to it and accuracy in unlocking improved much, but for every 10 unlocks I can still miss 1 or 2 times. It is no wear near the accuracy nor convenience of the one-touch sensors.
At first when I got the device I thought the scanner was garbage (I was garbage not the scanner :3) used to get 30-40% accuracy, I was swiping my finger on the scanner in same direction (downwards) everytime as instructed while registering, when it dint work well I turned it off, then I came across few threads n vids and understood I have to swipe my whole pad in from different variations and angles while registering I tried that and woila, I have almost 99% accuracy now, it works sooo soo good now, been using it since more than a week and I unlock it around minimum 50 times a day using it and also use some apps I've assigned fingerprint to and I've only failed once since I corrected the method of registering finger. so yup, awesome scanner much btr than s5 the only trick is to register from diff angles as shown in video n you'll be good to go.. :good:
I dont care how well it works with two hands, its the thumb on my right hand when using the device onehanded thats the "problem".
It works most of the time, and ive registered my right thumb in various angles and variations like in the video. But not all the time. Its fine for normal use, though, it really is. But if you have a shorter thumb than me, it might be a lot worse. Even for me, its a bit of a dud due to the fact that it sometimes doesnt register (my thumb might be slightly off center, or I swipe too fast, etc).
The more reasonable method would be a slimmer bezel at the bottom, drop the scanner on the homebutton, add a onepress scanner at the back of the device for your index, instead of that horribly useless heartrate/oxygenlevel monitor.
i tried the fingerprint scanner, did it 10 times to recognize it and set it but it didn't show up so i restarted my new note 4 and it worked and i swiped my finger and it unlocked then i locked it again but the fingerprint scanner went away again and its only giving me an option to swipe to unlock.
I tried to set up the fingerprint scanner several times with different methods/angles. I was unable to get a good experience unlocking it with one hand. The iPhone is miles better in this department. Works almost every time two-handed, though.
The way Samsung design it sense is not good. You need gently swipe down which simply look stupid and troublesome.
This part no deny iPhone did it great by press and hold only.
Agreed. That being said, I dont see any real point of it. Its much like the UV sensor, the heartrate sensor and all that other jazz.
The fingerprint scanner is just pure garbage. Not sure why so many are blaming Samsung for not giving proper instructions? Everything in that video the OP posted is clearly explained in the fingerprint registration stage. It even has an animated finger that shows you how to scan different parts of the finger and different angles and directions. Its not that we have not registered the fingerprint properly, its that the scanner is just worse than ebola and aids combined. The poll results also support my assertion that the scanner is totally sh1t.

The fingerprint scanner is not jazz. If it worked properly most people could get some real use of the fingerprint scanner versus the UV sensor.
The only real use would be protecting certain apps and unlocking the phone. Both of which are easily doable with a PIN. that being said I don't have a problem using the scanner with one hand nor two, but it's not 100%, I agree it should have been better placed. Preferably at the back under the camera for your index.
I guess I get about 9/10 first try unlocks at this point, one handed.
I have tried all the methods and it still is mostly garbage for me. And it starts registering the swipe after a half-second delay which means you need to wait for the screen to turn on and for the arrow to show up - what a waste of time. It is also only 10% accurate for me (even when I have registered 15 different angles for the one finger I use). Maybe a software update will make it a bit better, who knows. For now - I will turn it off as before.
Maybe just register in the same-ish angles...
I still don't see what the problem is. I still have 99% success with my fingerprint scanner. It simply just works every time i'm using it.
Either you are setting the fingerprint scanner up in a wrong way, using it wrong, or there must be some problems with the fingerprint scanner.
I'm even tempted to make a video that shows how good my fingerprint scanner works just to prove it .
And lastly. Even if Touch ID on the iPhone is more easy to use, it's far from being more secure than the fingerprint scanner on the Galaxy S5 / Note 4. Because on Touch ID, you just presses directly on top of the home button on the iPhone, which leaves your fingerprint open to anyone who manage to steal your iPhone. On the Galaxy S5 / Note 4, you have to swipe to get it to work, which means that you are actually swiping away the fingerprint on the button as you swipe.
Because of that, a thief is going to have a hard time to find your actual fingerprint to use to open the phone.

If you can make a video where you at least 10 times in a row unlock the phone, while holding it comfortably in one hand, I'll believe you. I'm talking about unlocking it with the same hand holding the phone, not two hands. If so many people have problems with the scanner, Samsung either has piss poor quality control, or it's just inferior by design.
And have you ever used an iPhone at all? There's no usable track of your fingerprint after you unlocked the phone. Unless you have very greasy fingers, in which case you wouldn't be able to unlock the phone anyway.
Samsung did most things right with the Note 4, but the fingerprint sensor wasn't one of them.
This is ridiculous. We can blame Samsung for building a swipe-scanner rather than touch like Apple but what is this unlocking with one hand business? Look at how big the device is, I would think you have higher risk of dropping the device than it failing for you when you swipe with one hand given the device is top heavy based on how one would hold it if attempting to one-hand finger unlock.
However, if your device lays flat on a table when trying to unlock, make sure you get it at the same angle you registered it at...
Couldn't agree more.. Look at the poll... Clearly doesn't work like it should.

For me, having a fingerprint sensor is mostly for convenience. If I'm already holding my phone and have both hands available, it's not much faster than using a pattern or PIN code. Especially when I'm in a hurry or wanna check something quickly, pattern or PIN is much more reliable, because I'm "swiping too fast".

That is your use case. For my corporate IT policy, we require an 8-character (not just 8 digit PIN). This is effectively typing a complex password every time I need to unlock my device. The fingerprint scanner alleviates this pain and it has worked almost flawlessly on the S5 for me, let alone the Note 4...
If using the PIN or pattern works for you, you can ignore the fingerprint scanner then. Just another useless Samsung gimmick, right?
If you can make a video where you at least 10 times in a row unlock the phone, while holding it comfortably in one hand, I'll believe you.

Oh, even I could do that. That doesnt prove much though, just confirms that it works 10 times in a row. Doesnt take in to account a bumpy busride, or when youre in a hurry, or if it rained ever, or if youre nervous, etc.
I saw a video a while ago explaining why people with an S5 had so much trouble using the fingerprint sensor: part of it was under the screen and you had to swipe over a part of the screen too. Just like in the video you posted.
I for instance am able to unlock my note 4 by only touching the home button with my index finger. This proves the fingerprint sensor is completely in the home button. And also why there are no dots on the lower part of the screen indicating you should swipe on them like that tab S and S5

Fingerprint unlocking sensor on S10e, is it 100% reliable?

I'm so frustrated with my S10 scanner that I've decided to return the phone back to Samsung. I can't accept it in $1200 phone. I need to open the phone in an instant like I do on my $200 Moto X4, it's slow but it never fails.
My question to all of you, S10e owners is: does the side sensor on 10e works as supposed to? Am gonna take chance with it, I really like the S10 series, great phones, but they didn't make the sensor on 10/10+ right.

I have S10e and the fingerprint sensor is in the power button and for me it is a learning curve, but it unlocks fast. I had to re-register my fingers again after learning how to comfortably put my finger on the sensor.
I have an S10e. Although I wish the power button/fingerprint reader wasn't so high up on the side, it's proven to register my finger perfectly every time. Plus, it has the gesture option like on last year's models. Swiping down on the fingerprint reader pulls the notification menu down. That's pretty neat.
I'm very happy.
I must be lucky on my s10+, postponed update, did not adjust fps settings and it is working really well for me

S10e fingerprint works like a regular fingerprint, more accurate than those under the screen and quite fast (but not as fast as OnePlus 6 per exemple).
It unlocks the first time like 99% with my right hand, but is more unreliable with my left hand.
If you hold your phone with your left hand, I wouldn't recommend it.

I'm right handed and was having issues at first, but then I scanned my thumb when the phone was flat on the table and again when I was holding it in my hand and I've had much better success with unlocks.
Only time I mess up is when I don't get the placement just right, but that's more about getting used to under display fingerprint readers than anything.
i'm also very disappointed with this, hated it on the back with with my S8, this is the only reason I bothered upgrading, it only works about 50% of the time as you need to get it right on the mark.
What more infuriating is all the reviews show it working 100% of the time when its clear this is never going to be the case as the sensor is very small and very easy to miss.
effing useless, also considering returning it.
EDIT - i removed mine and put them in again, seems a lot better now, still not as accurate as review make out but now usable for me.
Did you guys try the under-display scanner after the day-one update ? I read it works well afterwards.
I think most people just need to get use to it, my first 12 hours or so I was frustrating as hell but the more I use it the more I'm getting use to it and now its working flawless for me and thats with the screen protector still on. I have both my thumbs and index fingers set to it and they all work great.
its occurred to me what this solution needs, an always on fingerprint icon on the screen when its locked, it will need to be quite dim and pixel shift in order not to burn in though.
Thank you guys for taking your time to answer, my S10 is going back(rma issued) and I've placed an order for 10e it'll ship on 3/14. As great as all those S10 phones are, it's really bad if you can't turn it on.
The position is a bit too high if you're left handed or using the phone with your left hand. Other than that, It's pretty reliable and pretty fast. I'm quite used to side the mounted fingerprint scanner on the Xperia XZ1 Compact and this one is definitely faster.
It also allows you to choose to have it always active (ie. you just need to place your finger on it) or require you to press the power button (maybe to avoid accidental unlockings or recognition). Oh and it also keep the ability to swipe to pull down the notification tray which is handy.
So far I love everything about the S10e except the software...much thanks to Samsung caving in to Google and blocking rootless Substratum. I haven't switched from the S7 to it yet because I'll have to root the phone for the first time to solve that customisation problem that irks me to no end. If, however, you don't require Substratum to be intact, you'll love the phone from day one
I'm returning my S10, the fingerprint scanner annoys me. I came from the 6T and thought the "ultrasonic" would be much faster and accurate, yet it is not. I'm thinking about the 10E, but the screen is a little small.
I'm debating if I should stay with the 6T or get the 10E....
I'm also returning s10+ for fingerprint reader, considering s10e, small screen isn't so much of a turn off as the small battery
the 10e will be my choice as a screen crack or damage can make it not function and what I read about protectors having issues over the scanner - meh... the button method seems far more reliable and ideal to me.
Yall know and update to fix the finger print reader is rolling out to fix the issues. As well dry hands are causing problems, try getting your hands moist then try it. It works much better for me and I don't have the update yet.

There is no such thing as a 100% reliable fingerprint sensor. In fact nothing is 100% reliable everything will at some point fail.
this is now a single frustrating issue on S10. fp is still very poor. Error rate is very high, speed is terrible (huge post fp delay, huge delay during recognition too, the reader literally waits until finger is released). Also coming from 6T and Mi9, which were much better and lightning fast.

Oh yes... the S10 fps rehashed! Been using my S10e for a while now and have no complains – except for the lousy updates distributions on part of Samsung. Securitywise, my SM-970U1 is @ May 1st as of Aug.3rd
Am gonna say the side fps is close to but not entirely perfect, very reliable, still. I use 3 fp(am right handed) Lhand index, Rh thumb and Rh index for an easy use. I can pick the phone off the desktop with my right hand simultaneously placing the R.idex on the sensor to turn the phone ON instantly. Or, I pick it up with R hand and place it in my L.hand palm reaching for the sensor around with L.index – don't even have to look at it, the phone turns On. Am using the R.thumb when I already hold the phone in my right hand but the screen has timed out. And I really love the so-called “small factor size” so easy to handle in and out of the pocket.
But frankly, I really miss the back sensor location, had S9+ and OP6 for a while before S10 now S10e and the back location was the best! Turning the phone On was done almost subconsciously by slipping hand into a pocket and touching the easy-to-feel dimple on the back cover.

Can anyone get the fingerprint scanner to work most of the time?

The fingerprint scanner on the Nokia 9 is terrible! Seems to only read it 20% of the time. I use face unlock sometimes which is nice but I can't always hold phone up to face. Tempted to just use smart lock with my android wear watch but there goes my security. May end up trying to add fingerprints again for a 3rd time...
Mine almost always works, but I have to apply some pressure to it. It's not like most other in-display readers that work with just resting your finger on the screen.
I have each thumb trained twice on it.
It fails completely with a glass screen protector (at least for me).
Worst scanner. Works 50 percent or less and with multiple scans of same fingerprint. Utterly useless.Ar least the Galaxy S10 plus was fixed with updates and my success rate is 90% + on that phone.

It's a painful fingerprint scanner, but I've found a way to make it reliable. Not necessarily convenient, but reliable..
Before scanning, I lick my thumb of index finger lightly, then run them together leaving them just slightly damp (just enough so they don't slide smoothly across the phone screen), then touch firmly, but certainly not hard, on the sensor patch.
Works almost first time every time. I also used this same method when training the prints.

Do you know where that thumb has been since the last time you licked it??? :silly: :silly: :laugh: :laugh:
I received my phone yesterday. My fingerprint scanner seems to work just fine. There are a couple times where it did take a couple tries, but it's been nothing like I've been reading. I'm perfectly content with it. I'll also add that it's been working just as well for me with a plastic screen protector on it.
You guys never had a xiaomi mi 5s. If so, you would not complain about fingerprint scanner ?
I've had about a 75% success rate with the fingerprint scanner. I set it up in a dark room and registered both thumbs and index fingers. There are times when it won't read my fingerprint at all, which seems to be software related. Other times, it will say not recognized. In those cases, I've tried to place my hand over my phone as if I'm covering my PIN at the ATM, creating a bit of a shadow or darkness over the fingerprint area of the screen and then trying it, which seems to work a lot more often. Covering it with the other hand might be a fluke, but I am able to repeat the results again and again.
Edit: I deleted my post, because it was not repeatable. Whatever the software issue is, its too intermittent to isolate through physical means alone. Someone with programming knowledge though should be able to see what might be causing the problem and provide some insight on a workaround until then.
Right now for me, it seems to work when its being charged and battery saver seems to affect its success rate.
for me it depends on the situation, sometimes it doesn't work at all. Things like temp etc seems to be influencing the succes rate. my xz3 has a reader at the back and it doesn't work sometimes as well. they are equal in reliability. But if you are used to a Huawei (like the mate 9) it is terrible. I really had to adjust when I got the XZ3 (coming from a mate 9).
I received mine this morning and it performed a system update out of the box.
I put a glass screen protector on the phone straight away and I've had some success with using the fingerprint reader, although not so much that I would like to use it all the time.
These are my observations so far,
- The 'press harder' message is deceptive. I have never got it to work by pressing harder when it tells me to press harder in a spot where my thumb/finger already is. Instead if I use that as a cue to re-position my thumb/finger then I have much more success. When it works, I have never had to press hard at all.
- It doesn't like my thumb very much. It takes some time to find the right position with my thumb, where as my forefinger is fine.
Update: 16:14
I've been persisting with it and have found the right amount of pressure to make it work more consistently. The message on the screen says press a little harder, and pressing it to the point where it flattens your skin out against the screen makes the chance of success better.
Moseman, i did everything you did, unfortunately its a software issue. You are right about the 'press harder' message, its not true. You don't need to press hard at all to get it to work, which i have been able to test successfully. The issue is not about pressure, its about placement. You must place your finger in the exact position that you placed it when you did the first half of the enrollment. Interestingly, i've noticed that apps that use the finger print reader as part of their login, seem to work much better. Such as ADP app or Bank apps.
You will notice that it probably works better while on charger, and works terrible with battery saver on. I tried many ways to find a workaround to get it to work consistently, but eventually it goes back to working 10% of the time. I believe they will create a fix here soon.
I've heard the face scanner login works much better. GL!
I got a good working scan by holding the phone in landscape mode while learning the scan. Might be coincidence , but i figured since the scanner is the shape of a flat rectangle it might cover more of my finger that way. (in normal use i just unlock in portrait mode, i just did the landscape thing to learn the fingerprint)
Interesting. I will try your method and see what i get. Will post an update later. Thanks Bk227865.
*Update: The method does appear to be working somewhat better. I will have to keep testing. Thanks.
*Update2: I don't know why im obsessed with getting this working. But BK you gave me an idea.
So after trying your method, i wondered if enrollment was the issue. Perhaps i wasn't doing it right, and maybe someone else did do it right, so let me know if you did the following.
I deleted all enrollments and tried again, this time with battery saver off (just to rule anything out related to that). I also made sure that my finger placement was exactly as described in the training photo. Originally and before, i had placed the edge of my fingerprints to the edge of the scanner, but actually it wants you to place the middle part on the scanner.
So when i re-enrolled using the exact finger placement the picture showed, it didn't work 100% of the time, but i do get somewhat better overall success with different finger placements.
Anyone willing to test this out?

I can vouch for this, great discovery, Sliksta! :good:

After further experimenting, it seems like the results are only slightly better and this is not a permanent solution.
Wow. Really improved! Almost 8/10 now
The way I did it was placing my thumb in different angles from the beginning. Don't have a lot of troubles with it. Some times the light just doesn't switch on. Direct sunlight doesn't help its accuracy. Wet fingers doesn't help as well. But I would say mostly it works
Thanks all and Chaosdark for testing. I still believe that battery saver somehow effects the consistency of its accuracy. I would say it works more often than not with battery saver off. This might be the inconsistency you are experiencing. Can you/anyone confirm it works better w/ battery saver off?
Today I think I've found something interesting, if you go to verification option in the fingerprint section under security and touch the FP scanner to verify which fingerprint enrollment belongs to which finger, I have found that it detects and identifies the fingerprints enrolled easily and quickly and doesn't ask you to press harder as often as on lockscreen ( needs more testing from other users).
This results makes me hopeful that a software fix is possible and in the making according to Nokia CEO how vaguely suggested there will be a fix in an upcoming update.
What do you guys think?

It's a painful fingerprint scanner, but I've found a way to make it reliable. Not necessarily convenient, but reliable..
Before scanning, I lick my thumb of index finger lightly, then run them together leaving them just slightly damp (just enough so they don't slide smoothly across the phone screen), then touch firmly, but certainly not hard, on the sensor patch.
Works almost first time every time. I also used this same method when training the prints.

Incredible

3 days in and disappointed

So iam now 3 days in with the S10 plus and i have to say that while theres lots i love about it , iam also disappointed. Here are my complaints thus far..... I pray some of these can and will be fixed with a software update.
1 - Camera, Yes its pretty good but i expected more. No better then the S9 imo. Expected a little more from Samsung with regards the camera this year.
2 - Kepad touch issues..... I virtually cannot type on this phone without constantly and accidentally hitting the 'p' key. I do not have chubby hands or anything but whenever i need to reach across to the left side of the keypad , iam forever hitting that 'p' key and it drives me crazy to the point where i may return the phone.
3 - No notification LED - This wouldnt be a deal breaker if Edge lighting worked properly but Edge lighting is pretty damn poor lets be honest. Works fine for default messaging app but thats about it.
4 - Fingerprint scanner - Was awful initially but improved massively once i removed the pre-installed screen protector and added a second fingerprint using the same finger. However, I still find that it occasionally fails to read my fingerprint. I feel like iam placing my thumb in the right area given that the icon lights up to help me but somehow it still sometimes fails. I would say it works around 80% of the time
5 - Fast Charging - Again i expected more. Its not slow but its not fast either. It takes around 1hr 45 mins to get from 15% - 100%
For me personally i would be happy if they could improve the keypad and fingerprint issue but theres already been updates and not much has changed.
You mention keypad, are you talking about the keyboard? If so just use another keyboard.

Tried another keyboard but same issue! Its the curved display ultimately thats the issue i guess not the keyboard. Although i also owned an S8 and S9 Plus and neither of them had this issue!

You can modify the size of the keyboard for this very reason, move it up or down until you can use it comfortably.
You can also modify the curve display deadzone with goodlock.
I'm also surprised that AOD doesn't fill the void of a notification led.. it certainly does for me.. In saying that I would like to see a notification ring around the camera cutout, I think that would of been a nice touch.
I agree with you on everything you mentioned.
I would add one more thing regarding accidental touches, I am a skinny guy, and so are my hands, but whenever I am reaching to other side of the screen, I find the screen either not responding to my touches or causing accidental touches, what drives me crazy is that I check the palm of my hand and almost always it's not even touching the edge of the screen, it's as if even when your skin is hovering few mm above the edge if the screen the phone will take it as if your actually touching it, if that makes sense.
As for the camera, coming from the Note 9, I am so disappointed with the low light capabilities of this phone, even indoors it's not up to par with other flagships, I even get worse shots than my previous Note 9 and S9. To make matters worse, Samsung didn't include a propper night mode that can compete with Huawei's night mode or the Pixel's night sight.
Sorry for my bad English, I hope I was clear enough in delivering my point. Cheers.

Have you tried disabling Touch Sensitivity? I had some issues at first, but after disabling touch sensitivity, it improved a bit.

The S10 does have a Multi Colored Notification LED around it's camera cutout. This YouTube video explains how to activate and manage it.
https://www.reddit.com/r/Android/comments/b0p0o6/s10_s10_how_to_enable_led_notification_light/
Try using a light touch on the fingerprint display reader as opposed to a hard press, this is how it's designed to function.
The S10 Camera has a Pro Mode, you can adjust virtual any aspect of photos to your preference.

That notification is from using a 3rd party app and a light touch with the screen protector hasn't worked too well.
I am the same my main issue is the led notification for WhatsApp
Already thinking of going back to my old s8
Keyboard I am also having issues with clicking on the wrong keys

I contacted Samsung about the keyboard issue! All they suggest is to leave feedback. If your using the stock keyboard then it can be resized which i guess kinda is a solution but you have to bring it in from both sides to keep it centered and the keyboard then winds up been a tad too small so its not ideal! Its weird because my s9 plus was almost identical in terms of its dimensions yet it did not have this issue.
fingerprint scanner has also been a nightmare today! I could swear iam not doing anything different yet it works sometimes and rejects me other times. Its makin me miss the finger print scanner on the s9. It was so much better. Another small annoyance is how fast my battery goes from 100% to 99% lol
Battery in general is great but i charge it to 100%, Unplug it and seconds later iam at 99% .......... what the fudge ha
I used an iphone xs temporarily recently and i have to say that while it is over priced and in general Samsung is much better and cheaper too. However, Apple does things properly. It worked flawlessly and never gave issue. The Samsung is far better on paper and ticks all the boxes but in day to day use its just not as 'perfect'

Question Finger print and lock screen

The success rate hit of the finger print scanner is much lower with the lock screen than with the screen saver. While with the screen saver it is effective and quick , it more often than not that with the lockscreen the fingerprint identification is rejected.
Any ideas? solutions? I already deleted and printed new finger print few times already.
I find that it's total garbage. It works about 10% of the time and I've redone adding my prints over and over. I've tried most of the steps others have and find that it doesn't help. Someone said to do a factory reset and no I'm not going to do that. I just don't use it anymore and will probably get rid of this phone soon. I want to use SD cards again and have more memory as 512 is just not enough. The reader on the Note 9 was so much better.
Not sure what you guys are doing or not doing, but my print reads all the time whether screen is on or off. Get use to where the sensor is also make sure you don't have dry hands
No complaints here. Work 99 out of 100 times on both screens
Can't complain either, working perfect here and very fast, too... Btw with stock screen protector, if that matters....

I am doing all of the above , just when AOD is active the success rate is vey bad , when normal screen saver is on , the success rate is much better.
Tnx
I was having no issues before a screen protector.. now I don't even use it because I can never get my finger print to read.

Screensaver, AOD, screen off.. Success is 99/100
Are you using a screen protector/shield?
I have learnt I need to press harder. I used to have a Pixel 2 XL FPR on the back which was really sensitive. Using a phone with FPR under-screen was new for me, you do need to be firmer when pressing your finger down and after training myself for a few days I don't have any issue with unlocking now. I have fitted two S21Ultras (mine and friends)with the White Dome tempered glass and that has not impacted us either.

It's hard to miss where the sensor is as it's pointed out on the screen when using it. As for dried hands that too seems not to matter.
Folks I'm guessing you think you're being helpful when you say that you're not having a problem with your phone as a response to someone who is have a problem. To me that's like me taking my car to a mechanic and telling them my car isn't working properly and them telling me that their car is working just fine. I worked for many years as a computer consultant at a major university in upstate NY and never once did I respond in this fashion because it's pointless.
But he was wondering if his phone was faulty..you being an analyst should realise that if most of the replies are positive that in itself helps him

Im guessing you think we can solve a problem thats either a defect or user error.
oh wait. guess we can just close the thread then.

Hi.
No , as it was unpacked from the box.
This has started to be an issue on my a.o.d.
Was ok but I changed the icon and it seems to be hit and miss now.
I just double tap the screen and bypass it

My Icons also changed , so that might be the issue.
Problems solved.The cause of very low hit rate of the fingerprint scanner on AOD in lock screen was new icons i dowloaded from Galaxy store.When i installed the original , no more missed prints
No complaints here. But it completely works
