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.

fingerprint unlock is acting up

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.

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.
---------- Post added at 05:57 AM ---------- Previous post was at 05:54 AM ----------
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

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.

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 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'

Changed cracked screen, fingerprint sensor issue now.

I live in Toronto and considered myself lucky to find someone to change my cracked screen. All seems great, accept now my fingerprint sensor isn't rally working. Every other aspect seems to be perfect. Anyone had this issue? Anyone changed screens? Anyway to reset the fingerprint sensor other then erase and try again?
Any help would be appreciated.
TIA.

Maybe he forgot to reattach it and your phone basically has no fingerprint scanner now? Idk open it up and look for yourself.

Thanks.

Was it an AMOLED screen, AliExpress sellers are now selling TFT LCD replacement screens, alongside AMOLED screens, at about half the price. LCD screens aren't good with FOD ordinarily.
I replaced mine back in December with an AMOLED, but I've been on custom ROMs where the FOD isn't as good as stock anyway, so couldn't say if I'm getting as good performance as before. It recognises my left thumb 9/10 and my right thumb 5/10, and never as fast as stock, which seems about par for the course with custom ROMs. I considered flashing MIUI just to test the FOD properly after fitting the replacement screen, but never got round to it.

Thanks for getting back to me, yes it is an AMOLED and I do have an update!! It works perfectly once the screen is on. If I remember correctly I was able to use the scanner from the lock screen with the animation of the fingerprint.
Now I can only use it if it's in the on position showing the time etc. so I just used lift to wake so it works 100% now.
Thanks for the attention.

I have the same problem, caused by replacing it with a screen from a random ebay seller (local warehouse).
After looking through a few Aliexpress listings I noticed that some product descriptions contain a note that they sell only a compatible part, not an original. Others state "100% original" or something along these lines. And many just don't write anything... I assume most of them are fake, if not all.
It is definitely a OLED, but the fingerprint gets almost never recognized, it is hard to complete even the fingerprint setup. Only works if I increase the brightness manually. The screen goes somehow much darker in fingerprint mode, instead of making a bright cyan dot like the stock part. Enabling the screen before unlocking helps on mine too, I think the reason is the higher brightness there, but still not as good as before with the standard screen.
In addition the image is a bit worse, especially looking closer at solid grey, it looks grainy. Normally it should look clean. Do you see that as well?
Scrolling is also not as good, doing a fast fling results in a much slower movement than with the stock screen. It works and might not be as noticeable, but having two devices side by side reveals quite a big difference. I bought another 9T just to try this...

I doubt my screen is original, but it's definitely good quality. There's no noticeable screen quality issues, either with display resolution, colour or motion. Haven't compared it against another Xiaomi/Redmi display, but against other FHD+ 60 Hz AMOLED displays on a mid range Samsung and a top range Honor, it's just as good.

I have the same exact issue after replacing my own screen. It seems to have to do with the finger print animation lighting up when your finger gets in contact with it.
I've disabled the finger print method completely and that seems to help.
I'm not sure how to fix this though, as I would like to use it the way it was intended myself.
(btw factory resetting the phone helps with the success rate of the finger print sensor if you haven't tried that)

Perhaps if you need to buy a new display, I bought the "AMOLED Black" variant available here. Has been replaced on a Mi 9T, everything works fine and it's as good as the original display. It seems like the price has dropped significantly, almost 50%.

Yes, it's all working. I only have no idea what the difference is between "AMOLED" and "Original". I assume that perhaps Xiaomi certifies those displays as original, however, they're most likely the same as the "AMOLED" displays, maybe with slightly better color accuracy. I didn't notice a difference between my Mi 9T Pro and the Mi 9T with the replaced display.

I changed the display but I have problems on my MI 9T Pro with MIUI 12.
5 dot instead if 10 dot touch.
Double Tab To Wakeup didn't working.
Fingerprint sensor didn't working (restarts after using).
All these points are working on your phone with this display from AliExpress?
If yes, I will buy this display too .....perhaps .....

It's not my phone which has the replaced screen, but from what I know, everything is working. Besides that, they're quite cheap now (I had to pay double for what they retail now since it was cracked roughly half a year ago). The total job would cost you under 100 euro to get it replaced.

The screen used on my device was this link (the amoled model) and everything you described is working perfectly:

A summary of the situation:
Until MIUI 11, the MI 9T / K20D [PRO] worked normally even when their screen was replaced by non-original screens with only 5 multitouch points, sometimes described as "tft" or "oled", including the fingerprint scanner.
Most of the screens available on internet sellers are of these types, and vendors often insist that they are original. The easiest way is to check the number of multitouch points, if it is not 10, it is not original.
After upgrading to MIUI 12, the fingerprint scanner of the MI 9T / K20D [PRO] equipped with these screens no longer works, restarting the device whenever trying to register a fingerprint. This is not a calibration problem.
The only solution found so far is to replace the non-original screen with an "AMOLED" screen, with 10 multitouch points, which is either original or at least has characteristics similar enough to the original to work.
This topic has a good explanation on that subject https://forum.xda-developers.com/k20-pro/help/miui-12-fingerprint-unlock-defective-t4122135
I hope it helps

Question ZTE Axon 40 Ultra, my opinion after couple of days.

Hello all, finally I bought this phone, the 12Gb RAM 256Gb.
I've been using it for couple of days, I consider myself a power user as I need to do a ton of stuff with the phone due to my job, and this are my conclusions in this 2 days.
I'm coming from a K30 Pro Zoom with Xiaomi EU ROM, for those who don't know it's a very customizable ROM, very well known, and works flawless.
ZTE Axon 40 Ultra
Hardware: 8/10
+Lighter than I thought
+Very good built quality, nothing to envy Samsung's S22 Ultra.
+Awesome uninterrupted screen, it's a joy to look at FHD+ it's perfect IMHO
+Cameras, the 35mm equivalent feels more natural then other phones, I haven't fully tested them, but so far so good, and mi K30 Proo Zoom has a very good set of cameras too.
+Speakers are also very good, I wouldn't say top tier like an iPhone or S22, but step below the top.
-Very uncomfortable to hold in one hand, not because it's form but because it's insanely slippery. Wearing a case is a must, and I don't put cases in my phones ever.
-Hidden selfie cam is trash, but I almost never use the selfie, just lo let know people who might use it.
-Camera module makes the phone rock on tables, kind of annoying IMO
Software: 6,5/10
+Animations and SO in general are smooth and crisp.
+Zero bloatware
+Camera menus are complete and easy to use
+Android version is very light
+Very good battery life. This concerned me because K30 Pro Zoom was a beast in battery life, the Axon is very good too, not as good maybe, but good enough to don't kill it in one day.
-The fact that I can't unlock the phone just with my fingerprint and I need either to press first power button or double tap to wake up the screen, and then scan the fingerprint, drives me crazy. I mean, this should be working on any phone.
-Double tap to wake up, or move the phone to wake up are terribly slow, around 3-5 secs. Completely useless.
-Swipe up, home gesture, gets frozen some times, and it's inconsistent depending on what app are you in, very bad bug.
-Text to voice does not work if "hey google" is enabled. I mean, really?
Hope you can find this comments worthy
I might be updating it with new info

*Update.
Fingerprint scanner now works fine after a hard reset, so when I said " I can't unlock the phone just with my fingerprint and I need either to press first power button or double tap to wake up the screen, and then scan the fingerprint", is no loger a issue in my phone.
Please share your toughs, and bugs, wit the device so we can learn from each other

I'm getting an 8/128 version next week. Principal use besides basic phone function is for still photography. I assume the usb driver auto installs. I won't have room for all my photos on the phone anyway, so will do most of that on pc.
