Got my replacement unit yesterday. Finger print worked fine but the screen was so blue drove me crazy so im shipping back today and gonna wait for a 3rd device.

I also did reset to factory and cleaned the finger print reader with some cotton swab and alcohol and since last night fingerprint is 100%...

No sure whats going on by im gonna wait for a 3rd device and hopefully it will have good finferprint reader and a screen..

---------- Post added at 08:53 AM ---------- Previous post was at 08:50 AM ----------

forget what I said, having issues again with Amex (cant recognize)

Will report back with the 3rd device.

F annoying..

For me unlock the device works 100% just those 3rd party apps are a hit or miss..
[Google Pixel 2 XL Questions & Answers] HodoryGT:
Forget what I said also. It only took less than 24 hours for the fingerprint sensor on my replacement Pixel 2 XL to crap out yet again. Unlocking the phone is doable but inconsistent, and the 3rd party app sign in flat out does NOT work. 5 fingerprints registered, tried registering with different angles, NONE of that works. I would even unlock the phone with the sensor, immediately followed by attempting to sign into a 3rd party app, only to be rejected and kick me out.

I am sorry, but this should not be happening. Never have I had so much problems with the sensor with any devices I have owned in the past 4 years. And I REFUSE to do another factory reset again. I have done this probably 12 times already.

What's even maddening is that nobody is talking about this in review/blog sites, and not even Google is addressing the issue.

If this continues again into tomorrow, I am returning this again and will not come back to this overpriced product that can't even do basic function correctly.

Is this issue only occurring with the larger XL model? Or is the smaller model having same issue?

EDIT: ALL 3rd party apps, EXCEPT for Dropbox is NOT working with the sensor. For whatever strange reason, Dropbox allows me to log in with the fingerprint sensor with no issues at all. This is all too confusing and puzzling.
[Google Pixel 2 XL Questions & Answers] Nephilim:
Nobody is talking about this in review/blog sites because it is not a widespread issue, it's quite rare actually. If you watch most video reviews they praise the sensor. I myself have a perfect fingerprint reader as does my mom whom I bought this device for as well. I had to get a replacement due to burn-in and both the first and the replacement have perfectly functioning scanners.

Now I'm in no way saying your issue isn't real, I completely believe you, but, it sounds like you need to get a replacement. Most likely your particular device scanner is outright defective.
[Google Pixel 2 XL Questions & Answers] HodoryGT:
I hope your burn-in issue has been resolved. That must have been painfully annoying.

Let me ask you... you say you have no problems with your scanner. Are you using any 3rd party apps that lets you log into the app with the scanner? If so, what apps do you use, and do they all function perfectly?

The reason I am asking you is that... the more and more I test, the more I start to believe that this is a software issue. Right now, the phone is getting pretty consistent at unlocking itself. But 2 to 3 seconds after unlocking the phone with the sensor, all the 3rd party apps (Except ONE, which I will mention below), flat out do NOT work. There is no way a scanner can get so dirty in a manner of 2-3 seconds on a consistent basis to crap out on you. Not to mention each press of the finger was done exactly the same way and at a same angle used to unlock the phone from lock screen.

The ONE exception is Dropbox. It works 100% of the time. I tried it 30 times already, no fails. So here we have ONE app that works, and all the other apps that don't work. How can this be explained?

Thankfully, I don't have any screen issue and the phone functions beautifully. I seriously think Oreo has something to do with this. If you dig deeper in the internet, there are forum posts where people talk about scanner not working immediately after updating their perfectly-function OG Pixel phones from Nougat to Oreo.
[Google Pixel 2 XL Questions & Answers] ShayMagen1:
I also start to believe it a software issue since I can unlock the phone with the fingerpring %100 no issues but for 3rd party software is like hit or miss but sometimes can work good for a full day..
[Google Pixel 2 XL Questions & Answers] Nephilim:
I use my banking app, the my Verizon app, the GameStop app along with a couple others I can't think of off hand right now. They all work perfectly, instant login. If you believe it may be software related maybe sideload 8.1 beta and see if that helps.

Personally I feel it is a device defect due to it saying the scanner is dirty. If if was an issue with software it would just say unable to read not that it's dirty. It appears more likely the hardware is broken and thinks your fingers or the scanner are dirty.

Either way, something is not right. Maybe try 8.1 and if that doesn't work get it replaced. I myself had no issue on 8.0 or 8.1 but it's worth a try.
[Google Pixel 2 XL Questions & Answers] erojas388:
Received my rma device a few days ago and i can happily say this fingerprint sensor is working great. On top of that this screen is less blue than my last. So don't be afraid to rma if you have to.

---------- Post added at 10:01 PM ---------- Previous post was at 09:59 PM ----------

I use the chase app, amex, citi and paypal and have not had an issue with them while the last phone they didnt read my prints about 50% of the time.
[Google Pixel 2 XL Questions & Answers] joe8617:
Same problems here. There is definitely a problem with the pixel 2 XL fingerprint system. Works fine for a few hours or a day, then it no longer works to unlock the device. Such a bummer. I have just a few days to return the phone for a refund. If I knew a fix was possible and in the works, I would keep the phone. I doubt I will get confirmation of that within the next 3 days....
[Google Pixel 2 XL Questions & Answers] Nephilim:
Dude, that's a factory defect not a common issue on all devices. Get it replaced under warranty. I don't understand why you feel the need to get a refund when this issue does not effect the majority of Pixel 2 XL owners. Seriously, it's like everyone just assumes that if their device has an issue all the other devices will have that same issue, which is not true
[Google Pixel 2 XL Questions & Answers] ShayMagen1:
I got my RMA yesterday, had the worst blue screen... Sent it back today and gonna have another RMA hopfully with a better screen...

I think its madness that we need to hope for a good device and its consider lucky to have a working fingerprint and a decent screen...
[Google Pixel 2 XL Questions & Answers] Nephilim:
The screen I get but nobody has hope to get lucky on the fingerprint scanner, you are the minority, it's a very uncommon issue.
[Google Pixel 2 XL Questions & Answers] joe8617:
Thanks. I contacted project fi support, they told me that the issue had already been elevated to Google's development team, and that they are working on it. If you read the threads about the issue on various web sites, a lot of people have returned their phones, receive new ones, and experience the same issue. I totally believe that it may not affect all devices though, and I wasn't trying to say that.
[Google Pixel 2 XL Questions & Answers] HodoryGT:
Well... minority or not, if I RMA again, this will be my 2nd replacement. To be honest, one time could be a fluke... 2nd time not so much... at least for me. I really like this handset but the scanner problem is a deal breaker for me. I am contemplating on what to do... Still within the return period, so I may opt for a different phone altogether.
[Google Pixel 2 XL Questions & Answers] nageshv24:
I have the regular Pixel 2 and facing the same issue. Going by some threads here and other forums I have read, many are experiencing the same. Wondering how come both versions are having the same issue with different hardware?
[Google Pixel 2 XL Questions & Answers] Pecata:
I am on my fourth Pixel 2 XL. All but this last one had screen defects and the second to last had screen and fingerprint scanner issues - the phone wouldn't recognize my fingerprint about 80% of the time. With this last device my screen is good, however my fingerprint scanner wouldn't work with third party apps...it will say not recognized, the phone unlocks fine...I believe this is some kind of software issue...
[Google Pixel 2 XL Questions & Answers] merkage:
I am receiving my 3rd pixel 2 XL device today, due to issues with the finger print reader on my second one, major screen issues on the first. I noticed Google put out a system update to the Pixel XL 2 this morning. The finger print issue is most definitely real. Project FI support told me 3/10 devices have some kind of issue being reported.

Curious if anyone can link a fix list for this update, I tried searching for one but came up empty. I'd like to know the issues they are addressing with each update.
[Google Pixel 2 XL Questions & Answers] ShayMagen1:
I believe that it is a software issue for most and some (small amount) people have actual hardware issues.

The reason I say that is because in my case my phone unlocks with fingerprint 100% of the time and 50% for 3rd party banking apps like Chase and Amex.

I did a little experiment now so my issue usually is trying to open chase and I keep getting not recognized for 4 times and then it locks so I tried to login to Chase

and I got not recognized twice, I immediately switched to dropbox and it worked right away. I also noticed that Chase is much worst compared to Amex but with dropbox which is not a finance app my fingerprint works 100% just like device unlock. I do believe that this is a software issue related to banking apps. If you have any other 3rd party apps with fingerprint let me know so I can test more...
[Google Pixel 2 XL Questions & Answers] Voicebox:
I think the older ones were more likely hardware and more recent seem to be more likely software. I had no issues until out of nowhere yesterday, I maxed out attempts on every app with a fingerprint. Earlier in the day, Discover logged in, then said they were sending me a text to verify id. So it was like they weren't quite sure it was me. Then later fingerprint just didn't work.

In between things working and not, I did have to reinstall hangouts to try to get rid of an echo on Project Fi calls, and that reset all the Google stuff, including Android Pay. That was after Discover logged in but sent that text as an extra step. But before everything stopped working. So I thought it might have something to do with that, but then the forums here and at Google seem to have a bunch of people having it all of a sudden.

I redid all my fingerprints a few times. One finger seems to be closer to 80% logging into some financial apps. But others fail all the time. All unlock the phone and Dropbox.

I get the feeling that there's some level of matching that can be set by the app creator. So unlock the phone is 90% match (making up numbers), Dropbox is 90% match, but Chase is 97% match, Discover is 98% match, etc. However, if that is the case, it could be defective hardware causing enough mismatch to push it past the criteria.
[Google Pixel 2 XL Questions & Answers] Voicebox:
By some magic, mine seems to be working again, though with some errors. But apps will open before I max out attempts. I think they undid some update that was pushed out recently. I had finished backing up my phone and had gone to the menu to factory reset, when I thought I'll try one more time. All apps except one seem to be working like before.
[Google Pixel 2 XL Questions & Answers] mngdew:
That's what I noticed, too. Mine also started to work correctly with some hiccups a day after I requested an RMA.
[Google Pixel 2 XL Questions & Answers] swooperstar:
100% fingerprint fail on Ally Bank app and about 20% fail the rest of the time. I do have magisk though, never tried the bank app before magisk. November update.
[Google Pixel 2 XL Questions & Answers] HodoryGT:
Okay, so an update. Maybe this information may help somebody here.

After my last post, I decided to try anything I can to remedy this problem. As you all know, I had problems with logging into 3rd party apps, all but two being banking or finance related apps. Dropbox worked 100% of the time, but Geico and all other banking/finance apps didn't work at all. 0% success rate.

Anyway, I took a good look at the fingerprint sensor itself. My phone is the black model, and the sensor looked completely clean, but I have read a few posts here and there that sometimes the sensor may come out of the factory dirty or may have some sort of residue, even if it isn't noticeable visually or by touch. So I grabbed a Q-tip and cleaned the sensor with rubbing alcohol.

Also, I changed the very method in which I laid down my finger on the sensor. I am used to the Touch ID on iPhones and the mechanism in Galaxy phones where all I had to do was to softly touch the sensor with my registered finger. It seems as though, however, that this phone requires the finger to be literally pressed into the sensor, not just simply be touched by it.

So with the combination of cleaning the sensor with the Q-tip and rubbing alcohol, along with the different finger motion on the sensor by literally pressing my finger into it instead of just gently touching the sensor, the apps that didn't work with the sensor started working again. This was last night, and now it's been 24 hours and the apps are now working with the sensor. Now mind you, these apps don't seem to take my fingerprint nearly as well as when I just try to unlock the phone. But at least they are starting to work, and I don't ever get to a point where the app locks me out of fingerprint login anymore.

I have no explanation for this whatsoever. I really wanted to keep this phone, as my phone doesn't seem to have screen issues, performance is great, and it feels great in my hands. The only issue was the fingerprint sensor, and now that it seems to be working again, I may just end up keeping this phone after all.

So for those of you who haven't tried, try the following:

1. Get a Q-tip, and clean the sensor with rubbing alcohol. Even if the sensor looks clean and feels clean by touch, do it anyway.

2. Instead of just laying your finger slightly over the sensor, try to... literally push your finger into the sensor.... almost like giving it a squeeze like as if you are trying to squash an ant with your finger.

See if this works for any of you.

In the meantime, even though my situation has gotten better, I still think there is something going on with the sensor in these phones... hardware or software, or combination of both.

For reference, the apps that I use which use the fingerprint login feature:

Geico Mobile

Paypal

My Verizon

Ally Bank

Alliant Credit Union

Mint

AMEX

Chase

Capital One

Barclay Card

Discover

Dropbox
[Google Pixel 2 XL Questions & Answers] ShayMagen1:
I also noticed that if you press hard enough it start working (Chase and Amex).

I also did a small experiment , my issue happens usually that chase or amex cant recognize for 4 times and I get locked (can use fingerprint to sign in even to open the phone)

So I got 3 times cant recognize on the chase app and im sure that if I would try one more I would get the same can recognize and get locked so once I got it 3 times I switched immediately to

Dropbox and it opened immediately (Dropbox for me is 99% success) so after dropbox opened I switched back to chase and it open on the first try... I do feel like there is a software issue and something triggers it... Let me know what you guys thinking..
[Google Pixel 2 XL Questions & Answers] jeffbartel:
Same issue here. I love this phone, but all of the issues are starting to get really frustrating.
[Google Pixel 2 XL Questions & Answers] shamdawg:
Same thing here. Phone unlocks every time but chase and capital one are very spotty. I'm on 8.1beta BTW.
[Google Pixel 2 XL Questions & Answers] plokm:
Question how does the sensor feels? Is it smooth or feels a little gritty? Mine was gritty so I rub it really hard with my fingers till it was smooth and now work flawless with 3 party apps

Also deleted all my fingerprints and rescanned them after I smooth the sensor
[Google Pixel 2 XL Questions & Answers] terre08:
I use BofA, Capital One, Geico and PayPal without any problems.
[Google Pixel 2 XL Questions & Answers] :
I think your guess is very reasonable. The bank apps might require higher level of match which becomes unrealistic for daily use.

I mainly use fingerprints on 5 bank apps: BofA, Citi, Discover, Chase, Amex. It is quite often that right after I unlock the screen with fingerprint, the same finger fails to log in one of those apps.

I am considering RMA. I really like this phone. I might be lucky but I have zero issue with the screen even the blue shift is not noticeable at less than 30-40 degrees (definitely noticeable after 45 degrees). The fingerprint reader failure with third party apps especially bank apps is the only thing I found subpar to iPhone (not to mention now iPhone has Face ID)

edit: my model is 64GB black pixel 2 xl
[Google Pixel 2 XL Questions & Answers] Voicebox:
You probably should consider an RMA since others reported serious problems as well. I don't recall any similar posts for other devices like my Nexus 5X. Zero problems with the fingerprint sensor on that phone. Usually people who had problems had it show as not available, versus work selectively.

Mine got back to "normal" in 2 days. I forgot to mention I had actually used a "Screen Cleaner" wipe to clean it off as well on the day it got better - Endust for Electronics. But I didn't "buff" it like someone else mentioned. I just cleaned it off with normal pressure for a few seconds. I don't think that fixed anything. I really think Google adjusted something since the Google forum just went silent after that night it lit up.

I did do a factory reset yesterday just to make sure since I can still return it for a few days. Of course I had to add fingerprints again. It now works normal. Though Discover did just get to the limit. Then worked after I entered password again.

I do have to get the finger more flat to the sensor versus I can do more tip of the finger to unlock the phone.

Apps I've tried out are:

Dropbox

Paypal

Starbucks

REI Visa - US Bank, but specialized app for that card

BofA

Discover

AMEX

USAA

Elan Credit Card - Issuer of many affinity cards. In my case Fidelity Investments.

HealthEquity

Transferwise

Discover seems most finicky. The other apps are working now. Dropbox always worked. No idea on Starbucks and Paypal as I only tried those after everything else was working.

The financial ones were the ones that had issues. Still are more sensitive than the others. I seem to have to be more intentional, like getting the finger flatter to the reader versus being more sloppy with phone unlock.
[Google Pixel 2 XL Questions & Answers] :
I had very similar experience. In most cases, I scratch the fingerprint reader with a face tissue using finger and nail and that solves the issue. But sometimes the face tissue can't save it either.

Do you think it is the problem of the coating? Does anyone with clearly white pixel 2 or panda pixel 2 xl have similar issue?
[Google Pixel 2 XL Questions & Answers] Voicebox:
I just looked at the 5X sensor and it is much smoother. Slick like you would expect of a fingerprint sensor. Where the P2XL sensor has a texture to it, which is like the surrounding area.

Also, the sensor is smaller on the P2 than on the 5X. Looks like 11mm vs 12 mm. Actually since it is slightly recessed, more like 10.5 mm.
[Google Pixel 2 XL Questions & Answers] ShayMagen1:
Same boat as you, phone unlocks 100% but banking apps are a hit or miss.

I also have a perfect screen and wondering if I should RMA or wait to to see if its just software issue..
[Google Pixel 2 XL Questions & Answers] Sodalitas:
Pixel 2 XL 128GB Black, fingerprint sensor works maybe 50% of the time for unlocking the phone. In Dropbox, it has ~90% success rate. In Deutsche Bank, PayPal, and Solid File Explorer, the success rate is close to 0%. RMAed the phone and waiting for the replacement device to see if it's any better.
[Google Pixel 2 XL Questions & Answers] Ap3xGam3r:
hmm got my pixel 2 xl on Friday and realized that I have a weird fingerprint sensor issue which seems more software rather than hardware: I realized that whenever I put my finger on the sensor wrong a few times where it tells me that my finger isn't recognized, even when I put my finger on it the correct way after (the way that always worked), it will not process my finger at all for like 10 seconds. Then after 10 seconds it will start working normally again until I mess up a few times again. So weird...
[Google Pixel 2 XL Questions & Answers] KAGroves:
I have had the same problem...pixel xl2, 128mg memory. Here could be a new twist... when I remove the case, I may find the problem “seems” to go away, more often than not. I have tried two cases, and still have the problem... my problem is with unlocking the device... I don’t use the fingerprint reader for other apps. I will call on a RMA, since this seems to be the path most have ended up choosing.
[Google Pixel 2 XL Questions & Answers] xavier6303:
I also have this problem. I'm on my 3rd 2 xl. Mine has about ~40% success rate on finger print phone unlock and bank apps. It seems after I use all attempts and wait the cool down period it usually then works for the first few times but soon stops.
[Google Pixel 2 XL Questions & Answers] Pecata:
I have chatted with Google on Sunday, they connected me to a ''specialist'' and he confirmed that they have received multiple reports on this issue and their engineering team is looking into it. He also said that they believe it to be a software issue that could be addressed with an update.

Feel free to contact Google and report the issue - they are filing them and hopefully we will see them addressed soon. Also use the provide feedback function within your device to let them know of the issues. That helps as well.
[Google Pixel 2 XL Questions & Answers] erojas388:
I'm sorry to say it but I believe this to also be a hardware issue. I have not had any issue with my new rma device compared to the one I sent back. I have the same apps installed and all my banking apps have worked perfect. The one I sent back worked 50% of the time on banking apps and also didn't work to unlock the device from time to time.
[Google Pixel 2 XL Questions & Answers] dpw2atox:
My p2xl fingerprint scanner acts very strange, most of the times it works flawless but then randomly it'll just stop working but then a few minutes later it works fine. It seems like it's more sensitive to dirt/wet fingers/etc than the sensor on my old Pixel was. Hopefully Google can improve things in a software update.
[Google Pixel 2 XL Questions & Answers] ZippCen:
Has anyone had the error: "Couldn't process fingerprint. Please try again"
[Google Pixel 2 XL Questions & Answers] gaw316:
I, too, have similar issues like this. 90 percent of the time it's fine, but then randomly it gets a little wonky. *Fingers crossed*
[Google Pixel 2 XL Questions & Answers] Phil_Ken_Sebben:
I had the following issue with my fingerprint scanner on my Pixel 2 XL: unlocking the phone worked 100% of the time with the same finger registered 3 times on the phone. Third party apps, especially banking apps and AT&T would fail 99/100 times. I returned my device for a full refund, and it really is a shame because I thoroughly enjoyed the phone. So my question is this to those who got a replacement XL: Is it still happening with your device? Does anyone know if the smaller Pixel is affected? I have two friends who got the smaller device and they seem to have had no problems. I am coming from an iPhone with Touch ID that seldom if ever failed to unlock the phone and never had any real issue with third party apps. Could this be individual apps that aren't optimized for the scanner causing the problem?
