Question Fingerprint Sensor problems - Samsung Galaxy S21 Ultra

I keep having issues with my fingerprint sensor... constant "fingerprint doesn't match" or "Press Harder" or "... cover the whole area..."
This is with a whitestone dome on the phone...
Anyone else having this issue?

I have a galaxy s21 ultra being used with a case by a company called you maker. It originally came with a plastic sticker that was protected and covered. That circular plastic sticker allows the finger to be read using the ultrasonic technology while being in a case. There's another technology that uses light to make almost a 2d image of your print. Try without the case and see if it works. Also sorry about you inconvenience.

well... there's no way i'm gonna take the whitestone dome off since its cured... just wondering if other peeps with WD tempered screens have the same issue with the fingerprint sensor

Had that issue with my S10+ as well. Try removing fingerprints then adding them again - assuming you didn't register after installing the screen protector. Another thing I had done was register the same fingerprint multiple times.

I have the WD screen protector on my S21 Ultra and I'm having issues with my fingerprint sensor also. I'm very disappointed because for the price, I expected it to be fully compatible with the fingerprint sensor.

The Samsung ultra comes with x2 screen protectors people rip the first one off or finger print sensor will not work i found this out the device has a second screen protector so no need to worry

Forgive me if this is a stupid question, but did you take off the factory installed screen protector that comes with the S21 Ultra? Not the one that you take off when you first remove it from the box (sort of a dust protector) but there is an actual screen protector there - very hard to see unless you look very close - if you did not remove that, then that is most likely your problem. If you did remove that before installing then I am not sure why you are having issues. Either way - best of luck my friend.

Only exynos variants come with screen protector, My U and U1 arrived without it. So just need to ensure finger print is re-registered. Did not use whitestone dome due to experiences with note 9 glass but the spigen glass is working well with finger prints once registered after application

Yes, I removed the original film that was on there. I also went to the "Display" menu and increased the touch sensitivity option. In addition to that, I registered the fingerprint of my thumb 3 times. I can't seem to unlock my phone in the 1st attempt. It usually takes multiple attempts for it unlock. From a visual point of view, the screen protector installed perfectly. I just wish it was fully compatible with the fingerprint sensor.

this is the exact same thing i'm experiencing!!! So annoying! I wrote to Whitestonedome and asked for a refund. Plus the bottom of the whitestonedome's glass is starting to peel ... even though it was cured and everything was fine for four straight days.
And no, the phone did not come with a pre-installed screen protector.

For what it's worth, the Fingerprint sensor works awesome for me. I have not added a glass screen protector and probably won't. For now, I am simply relying on the one installed by Samsung at the Factory - but I also have another Film Protector from AM-FILM that I will use if necessary. Very happy with how fast the FP sensor is - much better than on my previous phones....

Have both 21 ultra and whitestone dome glass installed. I have noticed that my finger slids a little not being use to glass as I tried for the life of me to use glass with my s10+. Couldn't get whitestone to work so I got zagg fusion glass. I have also noticed that if you have dry ass fingers, like after washing, it won't recognize your print. Try with lotion!

If only Samsung ditched the curved display for a flat panel, then we can buy "normal" screen protectors at fair prices.

The curve screen is a little annoying but also satisfying also

I have problems with original screen protector sometimes, registered finger only 1 time but I get same errors might just peel it off but don't know will it help any

I haven't removed the screen protector that comes with the phone from factory (not the one that you peel when you take it off the box... No issues with fingerprint sensor.. I had a note 20 ultra and I did the stupid mistake of removing the one from factory and putting one from amazon that had the circle for fingerprint.. I had to readd all prints and the worst thing is that it would miss more than hit. When I got my s21 ultra I was smart enough to keep the protective film that came with it. Other than that, I would suggest custom made with hydrogel (something I have seen where I live) which is flexile yet durable and works great with fingerprints.

I installed a generic £4 UV glass screen protector from ebay. Initially I had the exact same issue. But now it works for me. The trick I realised is to remove the old finger prints and re-register them. You will need to register the same finger 2 or 3 times and you will need to use a little more pressure when using the fingerprint scanner to unlock. It is still not as reliable as it would be without a screen protector and you will get a few misses but it gets the job done. I prefer using face unlock most of the time and use the fingerprint scanner only to make payments, access the banking app etc and for that it works fine I just need to press into the screen gently vs just placing my finger on the scanner as I would otherwise.

I don't understand how people claim that screen covers work perfectly well with with this phone's fingerprint sensors. i have tried AMfilm glass, and two soft ones by unique me and... even after the extra sensitivity was turned on, the fingers would fail most of the time. since you only get 5 tries before it locks.... so annoying... are the people that write those ratings all bs?? btw.. first experience with an ultrasonic sensor and it kinda blows..... am i out of luck? never had a phone without a screen cover ..... sigh

If you don't mind not having glass, a zagg will work for sure as I had it on my S10+. Currently running whitestone and if my fingers are just washed, it won't work. But if I rub them together or add lotion to my hands, it reads it with no problems. I have also added my print a few times in different variations like the side of my thumb and the tip of my thumb to make sure it can read any part of my thumb

Screen goes black when you make a call on 5.1, try this.

I'm not a screen protector salesman, nor do I have stock in one. This worked for me, but your milage may vary.
I updated to 5.1 yesterday and since then, every single time I made a call my screen would go black and become unresponsive. When the person at the other end hung up, it would eventually come back. I figured it was the rom and/or kernel. I tried as many rom, kernels and combinations as I could and nothing. I eventually found a thread sharing that the sensor became more sensitive in the upgrade and even if you never had an issue in 5.0, your screen protector is probably the issue. I thought no way, I paid like $20, really liked the protection and it never caused an issue, it was a tempered glass protector and clear as day, but I was desperate.
The second I took it off and pressed enter on a call, no black screen. I could actually make a call, cover the sensor with my protector and the screen went black.
I know it sucks, i really didn't want to change my protector, but I could not use the phone the way it was.

which screen protector? if it's not properly cut or is an old plastic type protector that's probably the problem. The good properly cut tempered glass screen protectors don't seem to have this issue.
Same problem here, but worse.
When the screen went black during the call, the phone shut down, and has been misbehaving ever since, I've still not been able to unlock it fully. I suspect the Device Protection feature of 5.1 (anti-theft) to be the cause of the problem...

I used Skinomi Tech Tempered Glass ultra thin, it was rated well. It did cover the sensor, but like I said, never had an issue on 5.0 and and once I took it off, worked like a charm. You have a suggestion for a good tempered glass protector?

Dang man, that's way past my "take the screen protector off" fix. I'm thinking you have a more complex issue. Were you unlocked and rooted? Custom rom or kernel? The allow oem unlock checked in dev settings? Can you do a full wipe and step through the flash process in fastboot?
Completely stock. I found a workaround. Remove the SIM card before powering-up. This time I am first asked to draw my unlock pattern, as it is supposed to do. Then, let the phone boot to my homescreen and then only I replace the SIM card. I am asked for my PIN et voilà.
I think the new anti-theft feature is indeed at fault. It is somehow overridden by the PIN request. Oh well, at least my phone works now

Regarding the screen proximity sensor problem.
Do you think a deliberately smaller tempered glass screen protector would work?
http://www.amazon.com/Orzly®-Tempered-Protective-Protector-SmartPhone/dp/B00ORYY4IO
Where is the sensor located on the screen? Between the camera and top speaker?
I've been using a Zagg GSP with the same problems... So far removing it has been my only fix. Didn't have problems before 5.1 even with some haloing!
I think the proximity sensor is to the left of the top speaker. If you hold the phone just right in the light you can see two little dots under the glass.

You should call Zagg at 18007009244 . I just called and they said that it was the first reported case, and that if enough people called in, they would investigate. They also said that you can remove the existing screen protector, use some other one, and just get a warranty replacement if/when a new Zagg GSP comes out.
Xtremeguard fixed this issue in their spartan glass. They also fixed the "halo-ing" issue many protectors have. They made cutouts for the camera and sensors. I'll post pics once I get home. I encountered OPs glitch with the original spartan glass I had (1st gen?).

Hey man, as I suggested, try xtremeguard. Here are some pics and they have cutouts for the camera and sensors. They usually have sales; don't buy it regular price, its ridiculous! Here's a code I found that works if you purchase two items: Spring90
Or if you want just one, use 75off
I just use their glass protectors on all my devices and I've had good experiences with them. They now ship their glass in a hard plastic case; less chances of breaking. Pictures attached!
Is this issue really just limited to people with screen protectors? I have the Zagg HDX and am having this same problem. I really don't want to replace my screen protector and don't want to have to go back to a non 5.1 ROM. Unfortunately I do spend a lot of time making phone calls at work and need to dial extensions which I'm unable to do because of this.
Are there any kind of Kernel modifications or system settings that can be adjusted to fix the issue?

Yes it really is. I had the problem on my Nexus 4 with a protector so I made sure to buy a protector with cutouts on my Nexus 5. I thought they would have fixed it on the Nexus 6, although it is still very sensitive. I had the problem with a full glass protector and my screen would stay off during a call even after using the power button. So I emailed xtremeguard and fortunately they modified their guard to have cutouts for the sensors as you can see in the pics I posted on the last page.
Same behavior with Skinomi tempered glass protector. Took it off and the phone works fine.

There was some talk about an issue with the sensors and 5.1 causing the issue also, but it seemed it was a small minority that had this issue. As far as I know, you have to bite the bullet and peel off the protector. I tried 3 different kernels and 3 different roms and nothing at all worked. The good news is they have plenty of cheap alternatives that have the cut-outs. Good luck.

Skinomi is aware of the issue. I wasn't sure what was causing it until i found this thread. Removed my protector and problem was fixed. It looks like Skinomi is aware of the issue though, contacted them and got a replacement since i had removed my glass protector. The replacement glass no longer covers the sensor.
No need to remove your screen protector. Just head to Accessibility--> Turn on 'Power Button ends call' and Boom!
I too had the same problem just after upgrading to 5.1
Tried this and it works like a charm. No issues till now. I hear that 5.1 messed the sensitivity of the proximity sensors. But lucky enough for us, 5.1.1 has a patch to fix this issue. Till you get an update for 5.1.1 just keep enabled Power Button ends call, and you'll be just fine. No need to spoil your completely alright $20 screen protector
Thanks!
The only thing that worked for me !
Hi,
I empathize with you. I found myself buying a Nexus 5 in India in 2013 with a lot of excitement and the same happened after upgrading to lollipop and then marshmallow. I removed am imported tempered glass screen protector and that didn't work. Next, I downgraded to KitKat 4.4.4 and that didn't work. Google's product forum was a waste of time. Their rep said the same things: remove the screen protector, clear cache and finally do a factory data reset. I'm not from a technical background and after saying prayers which I said only in my childhood, the below is what finally what worked for me:
1) Downgraded to KitKat 4.4.4. I have a MacBook so used this YouTube link:
https://youtu.be/pzzDxrccZO8
2) Rooted my device using King root. Link:
http://forum.xda-developers.com/android/apps-games/one-click-root-tool-android-2-x-5-0-t3107461
2) Installed Xposed framework. Link:
http://repo.xposed.info/module/de.robv.android.xposed.installer
3) Disabled the proximity sensor from Xposed framework. This YouTube link helped:
https://youtu.be/hPRujBMeuz0
Hallelujah ! I can see my screen again when making calls. Like I said, I'm from a human resources background and literally prayed like Armageddon had just started before doing all the above. I can't guarantee if these will brick your phone or put it in some perpetual bootloop mode, so do it at your own risk ! Started believing strongly in God but disbelieving in Android after this whole bloody experience.
Cheers !:good:

Does your galaxy S10 fingerprint scanner with whitestone dome work well? mine doesn't

I wan't to share my experience with my whitestone dome glass at the same time hear from you guys. i've been using my galaxy s10 with perfectly installed whitestone dome glass for more than a month now i've noticed certain things. some facts.
1.) i've installed it perfectly( 90% good)
2.) i've tried to scan every other way they suggest online
3.) tried to turn on whatever setting they suggest online
4.) i'm on the latest update ( my fingerprint scanner as well)
5.) i've notice that the scanner had a hard time recognizing my thumb hitting the scanner well, most of the time it would say please fill the entire scanner or press harder (everything i was surely doing)
6.) i'm talking about the galaxy s10 specifically
7.) to my frustration with it i thought about re installing the tempered glass (thinking maybe my installation was faulty)
8.) after removing the tempered glass, (without protection) WOW! it was faster, more responsive, and just amazing.
9.) i cleaned the tempered glass perfectly and re installed it again. it was a good install around 85-90% good. hoping it will work this time around.
10.) same thing happened it wont work well.
My conclusion: Yeah, s10's fingerprint scanner will work with whitestone dome glass, BUT it WON'T work great. (i would say it suck pretty bad)
How's your experience with it?
I returned the dome. Just to inconsistent with the scanner. Love the feel of the protector but was frustrating with scanner issues.
I changed to a cheap UV glue screen protector and it is alot better with the scanner. Mind you I really squeezed the glue out of the fingerprint area before setting with the UV lamp.
Nope, I posted this a while ago in the other section. I took mine off and put on a wet screen protector and it works so much better. Whitestone was a complete waste of money and the company is terrible. They told me the only way to get a refund was to return it unbroken. I would like to see someone take one of them off without breaking it. The one that I put on my wife's phone was so stuck on I had to take a plastic scraper to remove it. I will never buy their product again.
I took a blow dryer to the bottom of the phone and pressed hard on the fps area while I was uving it and that seems to make it so much better i dont get the press hard notifcations anymore unless I really don't have my finger on the screen
This was after I had it on for a while.

Note 10 screen question

Is it correct that you can't use a glass screen protector with the new fingerprint sensor under the screen?
Have look here
https://forum.xda-developers.com/galaxy-s10/accessories/galaxy-s10-screen-protectors-t3899458
There is tempered glass for the S10 so will be same for type protectors for the Note 10
Only reason I asked was that the first one I found on Amazon said it didn't work with note 10?

whitestone are expensive and looking at that thread easily break so maybe been thinner for the finger scanner . We should start to see more soon
So got the Whitestone one eventually - complete dud! Despite the price and the promises (and all those Youtube reviews - paid for??) the fingerprint sensor doesn't work.
Interestingly now I've looked at Amazon 50% are 5 star and 50% are one star in the reviews.
I don't understand why it works or doesn't. And yes I followed the instructions to the letter, reprogrammed fingerprints and switched on screen protector setting.
Anybody got one that works yet?
Some high quality tempered glass screen protectors for the Note 10 can work with the ultra sonic fingerprint scanner. The Olixar one seems to work

Have you used it yourself? Seems quite an obvious mark where the fingerprint sensor is - even the commentary mentions a rainbow effect - anybody tried this one?
Or what about the Alinsea Screen Protector? My first one failed with the fingerprint scanner as well but they are sending a newer model with different liquid?
Anybody?
Different liquid, same result. Total Fail
Anybody tried the above mentioned Olixar?

Adding a second screen protector on top of installed one

Wondered if anyone had done this. I am considering adding a second film protector on top of the pre installed protector from Samsung.
It says be careful of scraping nails on screen and I've noticed that it actually happens often that I scrape a touch of my nail harder than I should.
This seems like a very poor idea. It would affect image quality and might even affect touch sensitivity. I imagine it would just end up pulling up the factory screen protector anyway.

You should install not 1 but 10 or 20 more soft screen protectors in top of the one already applied!
What you need to do is remove the one already applied and enjoy the best quality of your 2k smartphone, if something happens before Dec 2021, pay the 150 and get a new inner display installed by Samsung! Enjoy at least a full year of your phone!
Ive owned both the Fold1 and now the Fold2 and being using them as dsily driver banging the phone around with tools and boxes while i do mechanic jobs! These phones are tank! My wife has long finger nails and never had a single scratch! Lets be honest, who tap their phone with a finger nail? Come on!
My 2 cents! Peace out...
Granted screen protectors are made to flex, the more you stack on top of each other, the less they'll flex. It'll cause it to stiffen and put pressure on the display. Doesn't seem like a good idea lol.

Yeap... that fold line is trouble.
It's also possible the plastic and/or adhesive could be reactive with factory one turning it into a gooey mess over time.
I'm actually thinking of doing this too. I prefer matte screen protectors to the shiny, fingerprint magnet that came with it. Maybe we could have the existing protector replaced with something else at the Samsung store or something.

Question Anybody curious about pre-installed Screen Protectors?

I have been using the device for a month, the front screen preinstall protection is clearly noticeable. My curiosity, the inside screen has pre-install screen protector? as it is quite flat (and no camera hold) so i am really not sure it is protected by screen protector or not, if it is there it is very perfect cutting and very unnoticeable. Any confirm?
I don't think the big inner screen had a protector. I put a matt one on though. Couldn't stand it. I need a protector on everything. Except myself it seems, 6 kids later
yes i think so, so i order one for myself also. Just dont understand the huawei instruction at serting up the phone that this device is pre-applied special screen protector, and they instruct even do not applied third party protector on top of it. So how do you feel when you applied another one on it, touch sensitivity is ok? and does it bubble when fold unfold several times?
