[Q] Home button gettings scratches so fast? Reason for faulty fingerprint scanner?

Hi
I have witnessed that my fingerprint scanner gets worse and worse. When I first got the phone, one fingerprint was enough to unlock the phone, now I have the same thumb on it 4 times to increase the accurate and it still fails often.
I tried clean my fingerprint scanner and under light, I could see it's full of scratches. The screen itself don't have a single scratch, so the home button glass/plastic looks pretty cheap, as it's tons of small scratches all over, even tho my phone is always alone in my pocket and never lying face down on the table.
Anyone else having this issue and could it be the reason, that a lot of people complain about the fingerprint scanner?
Thanks in advance

My advice would be to turn the damn thing off if ya don't like it... I certainly don't like it in my Note 4 , so I shut that crap off and just did it the old fashioned way. Lol I really doubt that the scratches are making it so it's not working good but that's my take on it. A fingerprint sensor would probably have to have some pretty good sized scratched to affect the sensor. I say that cause the sensor used in my iPhone is scratched to **** and it still works. I know it's 2 different pieces of hardware but all the same concept. And my S6 and Edge are both doing just fine. No scratches at all and a fully functional scanner! It's gonna take people time to use it correctly and by that I mean, you will have to find out the sweet spot and the right amount of pressure to apply. I have, and my screen opens up QUICK!

Screen protector discussion

I think I just ran into my first real problem with the phone. I got a glass screen protector on Amazon, and it absolutely refuses to recognize my fingerprint with the glass on it. The error just keeps telling me to press harder. I never had any issue before without one on.
Took the screen protector off, and now it's back to normal.
I have each thumb trained twice, so recognition shouldn't be a problem at all. I think it's just too thick and it isn't sensing enough pressure to register the fingerprint.
Anyone find a good screen protector that works with fingerprint? I may have to go with a plastic one that won't be as thick as glass.

This is disappointing. When I first looked into this, I found someone claiming to have tested the Oneplus 6T fingerprint sensor with 3 screen protectors on top of each other. I concluded it was not an issue. But now I am seeing plently or articles suggesting that it depends. E.g. "Vivo did mention that only screen protectors of a certain thickness will work with the sensor". I wonder if Nokia will offer or recommend a screen protector.
Also, I don't know if Nokia are using the same sensor as Oneplus, but this is interesting: "[when registering] make sure your environment is not too bright. If possible, you should register a fingerprint in a completely dark environment."
Edit, also spotted this: "We also recommend re-registering your fingerprint every time you add or remove a screen protector."

So as an update, I applied the second screen protector that came in the 2-pack. Removed all of my fingerprints that were stored, and tried to setup new prints.
Took me about 200 tries to get my right thumb registered (not exaggerating), but I couldn't get it to actually read when trying to activate it.
Couldn't get my left thumb to register at all. Just kept saying to press harder. I was pressing so hard I thought I'd break the screen if I pushed harder.
Tried in bright light, as well as a completely dark room. Didn't change the ability for it to register at all.
So overall for this phone, I'm going to say glass screen protectors won't reliably work with the fingerprint scanner. I've ordered a plastic screen protector. Going to try that out, as I'm pretty sure it will work.
I imagine the thickness of glass is the culprit here, due to how the fingerprint sensor works even without a screen protector applied. It seems more difficult to activate than other in-display readers (I have 3 others with in-display readers and they're all incredibly easy to use).

Fingerprint issues aside, I normally go for glass screen protectors because the plastic ones tend to cause more drag when using the phone.
I have generally seen two models. One which is clear and another which has a black border, both with cutouts for sensors, cameras and speakers.
I'm unable to add a link as I'm new to the forums but both examples can be seen on Amazon by searching 'GEEMEE 9h nokia 9 pureview'
Has anyone bought these or similar protectors?
I am interested to know if the black border one covers any part of the screen. I think it looks better on the pictures but in real life I'm not sure how it would look.

I got the Mr.Shield 9h glass and it works fine. The issue with the fingerprint is a software issue. The warning to press harder is not correct. I've verified that the reader will read with normal to light pressure. Hopefully they will release an update that fixes it within the next couple months.

I just got the screen protector with the black borders, and it doesn't cover any part of the screen. I think it looks good. But I was a bit sloppy when I applied it and one of the corners has an air bubble which I can't get rid of.
But since I applied it, the fingerprint scanner is causing me problems. It has problems recognizing my prints

I ended up going for a clear one tempered glass protector. I have a couple of tiny bubbles which was just me rushing as I was excited.
The finger print sensor works fine as long as I get my finger in the correct place but that is a challenge. My thumb is more difficult but still possible. It hasn't been a massive burden though because I have been using face and trusted bluetooth device to good effect.

Note 10+ fingerprint reader not registering prints

I got my new note 10+ and wanted to setup the fingerprint reader. In order to register a fingerprint it keeps telling me to press harder until I'm afraid of cracking it. I do have the increased touch sensitivity checked. I got the dome glass screen protector and installed it properly because it is supposed to be compatible with the fingerprint scanner. With it on, it is even worse and I can't even get a print registered. Anybody else having issues with the fingerprint scanner?

No issues whatsoever, but, that is with original Samsung provided protector. Did you remove it prior to adding the other one?

Yes I removed the other one. They had installed it crooked and one corner hung off the edge and was lifting up. So I took it off right away. I couldn't believe how thin the thing was.

Did you check for software update? There should be one which improves fingerprint recognition.

Did you place your finger on the scanner for 1 minute after the first 15 second cure of your Whitestone? I know the install vid on their website didn't show this step but I did it anyways and have no issues (basically did the S10/+ install)

Well I did as Whitestone support suggested. I removed the protector from the phone and got the adhesive off the phone screen. I reapplied the screen protector and all went well just like the first time. It looks and feels good. Very responsive. Tried to add fingerprints and again the same thing. It tells me to press harder. Since it is problematic without a screen protector I'm starting to wonder if there is a defect in mine. So far the only screen protectors that allow me to use the fingerprint scanner are the ones that are cut out where the sensor is. But those are rough when you're used to using slide typing!

I have received 1 update. I did not put my finger there within 15 seconds on the first installation. I did the second time. Oh well. I guess if I want to use the scanner I either have to get used to a protector with the cut out or go with the liquid glass.

Factory reset fixed my issue.

If you look at Amazon reviews on Whitestone about 50% have a total fail with the fingerprint sensor and for the other 50% it works fine.
I've had 2 and they both failed. I tried another type and it failed too.
Phone or protector? I can't say but you are not alone.
Currently, I have no screen protector on my phone for the first time ever

Issue is back again. It seems that unlocking the phone and registering prints are the most difficult. Once I'm finally able to get a print registered, it works great in apps for login and verification. But as far as unlocking the phone or trying to register the print again or registering a new print it is horrible.

have you set the screen to max sensitivity?

Yes it is set to maximum.

Improvements to fingerprint reader with system update PDF29.105-25-20

I did for sure! Sadly other issues are the same lol

I think so myself but I'm not using a screen protector are you guys? And if so what bad etc

Anyone use a glass screen protector and are able to use the fingerprint scanner?

I have unlocked model with Zagg glass protector ang fingerprint scanner works fine.

I will point out that even on stock firmware, only one of my 5 saved fingerprints was working properly. I deleted the other 4, and re-trained them while holding phone vertically (instead of horizontally laying phone down on a desk). Ever since, fingerprint scanner has been working great.
Only qwerky sometimes, when an app (i.e. Spotify is running and screen gets locked), end up having to hit power button, and then when screen officiallly wakes, then in-glass fingerprint scanner works..
Also noticed finger needs to lay with a specific amount of force on the glass...if too much pressure, or too little pressure, scan does not recognize fingerprint. After some practice, applying correct amount of pressure has scanner working flawlessly.

Accessories Whitestone Dome & Fingerprint Sensor

Has anyone else had a problem with using the sensor after applying the Whitestone glass screen protector? Is there a way to install it to make this better?

You should reregister your fingerprints after installing any screen protector. + you can turn on touch sensivity. (under display settings)

I noticed after going from my Spigen screen protector (had a glass feel but is a soft film) to the Whitestone Dome Glass on my S22 Ultra, I definitely have to press down harder (pretty firmly and no real wiggling of the thumb seems to work best) and use more full on thumb to get it to register properly. It takes ever so slightly longer to register and unlock for me than compared to the Spigen protector, but I do like the Whitestone Dome Glass more overall.

Putting on the WSD had no impact at all on my FP sensor. It was a bit finicky before and exactly the same after. I had found before I put the WSD on that it is 100% perfect every time if I moisten my thumb. Same after the WSD. With a dry thumb, most times it gives me the message "Cover the entire sensor" or "Press harder".
Things I did to help avoid any further degradation after install. During installation, pressed on the sensor area for about 30 seconds after the first cure and just before 2nd cure. Re-register prints after the WSD install. Set touch sensitivity on. Registered my thumb twice. After the install the FPS was exactly the same as before the install so no impact I can see. It is just that this FPS does not like dry prints. Moisten and many people find it works perfectly. I have found that I don't actually have to wet or lick my thumb, just breathing on it once is enough.
Because I generally use face ID to unlock, the FP is not a big deal to me. When I use an app like banking or Google Pay that require FP unlock, I do the breath on the thumb first and it usually works immediately.

4 - Fix Fingerprint Experience​Go to Settings, Biometrics and security, more biometrics settings:
- Turn off "Show unlock transition effect"
Go to Settings, Biometrics and security, fingerprints:
- Turn on "Fingerprint always on"
- Turn off "Show animation when unlocking"
- Set battery usage to "Unrestricted" for "com.samsung.android.biometrics.app.setting".
- Disable app optimizations for "com.samsung.android.biometrics.app.setting".

Do OtterBox cases and defender cases work well with this screen protector?
Want to know before I buy the device. Thanks

I'm using an Otterbox case with Gadgetshieldz screen guard and it fits perfectly because I got the case fit protector!

Next to redoing the scanning of the prints, I find that having to dry skin affects it often. See if handcream or just moisten the finger a very little helps.

Yes, as has been described before, I find just breathing on my thumb is enough to make it work perfectly every time.

A tip I learned a while ago was when I first cure using the uv light and remove it from the jig is to gently press down where the fingerprint scanner is before 2nd curing which in my experience certainly helps.

iam using ARMOR SUIT screen protector, work just fine

My first install was a complete dud as the fingerprint scanner didn't work at all, even after registering. I tried pressing down on the scanner on my 2nd install and while it worked better, it still only worked about 30% of the time after registering my prints again.
Unfortunately I'm sending my protectors back to Amazon for a refund as neither install method worked for me.

I guess the powers that be at Android are catching on to this. I just got an unsolicited system message with a few suggestions to make the fingerprint sensor work better. The last one on the list was to "try moisturizing" your fingertip. lol! Guess there is not a software fix for this coming anytime soon.

Hi guys, my film is slightly chipped on one side, it doesn't bother using it, do I still have to replace it with another one or do I leave it like this?
visually it doesn't bother me but it worries me about protection if I accidentally take a hit.

I personally, can not withstand chipped or cracked screen protectors, as soon as a crack or dent appears, I take the protector off, as it has already worked by absorbing the damage, but that is my opinion…

Yes, I have already replaced it, let's hope not to spoil this too, I need a better case but impossible to find what I want.
