Smudge on Mate 9 (black) fingerprint sensor - Huawei Mate 9 Questions & Answers

I have recently bought the Mate 9 (black version) and after using it for a while I have noticed that the fingerprint sensor area, even after cleaning it, remains smudged with an abnormal part that appears more polished and tends to attract oil, I even used rubbing Alcohol, but it didn't disappear. the sensor works just fine. Apart from this smudge, the device looks gorgeous, although the matt finish of the back of the device attracts fingerprints, but it can be cleaned easily. Does anyone have this problem on the black mate 9 or other color versions of the device? I have the Nexus 6p as well (silver) and it doesn't show any abnormal finishing on the sensor..

I know exactly what you mean. I have the brown M9 and I've noticed this too. I tend to just ignore it as it doesnt interfere with functionality. Would love to hear if there's a way to clean it though.

I have the same issue with my black mate 9

They break the proximity sensor (phone thinks it's near your head all the time). This is my experience, YMMV.
I guess you could cut a hole but it's bit of a PITA.

They're a little on the small side but not too bad, I had mine fitted perfectly and it covers only the actual live area of the screen width wise, and is a little short of the top and bottom of the glass height wise, maybe 2 or 3mm.
I just did a little testing of the proximity sensor with my hand, without the protector on, and it seems that the proximity sensor only turns the screen off when the phone is vertical not when laying flat. Might test some more with the protector. I had to rip it off to end a call earlier!
Just done a bit more testing and indeed, hold the phone vertical while on a call and put the screen protector on, screen turns off, take it away, screen turns on. When the phone is flat the proximity sensor does nothing so if you put the phone flat while in a call you can access the keypad etc.

I spoke to an SGP UK agent on Tuesday. He said SGP are revising their design to allow for this. Said should have the new version sometime next week.
I have some cheap screen protectors that used to cover my SGS2 proximity sensors and had no problems, guess I'll report back when I get my phone ):
I have a BSE on order. I hope that doesn't do it :'(

If any protectors do cover it, a hole puncher should take care of it pretty easily. It may not result in the prettiest results, but it will get the job done until all of the manufacturers revise their designs to not cover it.
That works well enough for now

I bought from same seller in ebay, not a good fit (very short) and have proximity sensor issue as well.

[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.

less responsive touch

So I got my OnePlus 7 pro today and have noticed that the keyboard is less responsive while typing especially near the sides of the curved schedule. Let's like "a" and "p/l" take a couple of attempts before they register. I'm coming from a OnePlus 6t and never had this sort of issue. Anyone else noticing this?
I definitely felt typing is isn't as good as my 6T
Heck at times it's for for downright cumbersome. Like typing this out took forever. This is a huge disappointment and I'm surprised none of the reviews mentioned this. I'm thinking of returning the phone because of the unresponsive touchscreen. Also wondering if my unit is defective...
Interesting I thought it had something to do with my screen protector ummmm

Are you sure this isnt something that was intended? I mean, maybe they did this so it wouldnt get these random touches om the edges? Im not noticing this tho om my 7 pro.. i mean its there but not an issue som far since i never put my finger that far to the edges while typing ?
Ok so I installed a tempered glass screen protector as soon as I got the phone before even turning it on. Thinking that might be the culprit, I took it off and noticed a huge improvement. Guess I will be using the phone without a screen protector. I tried to feel if there is a preinstalled protector like one that came with the 6t but I don't really see it on the OnePlus 7 pro. But based on a Google search OnePlus 7 pro does come with a preinstalled protector. So guess the glass protector not really necessary anyways.
If this screen comes from the same series as Note 8, then it could be the protector you might be using. I don't have this issue. I'm using the film protector it came with.

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.

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.
