Fingerprint reader word of advice. - LG G8X ThinQ Questions & Answers

If youre struggling with the in-display fingerprint reader then read this. I was having a terrible time with mine, reprogramming it over and over trying to get it to work consistently. Well i finally figured out what it is.
You need to very lightly rest your finger on the reader and it will work every time. Dont press hard at all or it wont read your finger correctly.
:good:

Even while using the light touch approach, it still wouldn't unlock just now when i woke up. Seems it need a software update or something.

I've got a screen protector and to me it seems the opposite. When resting your finger gently, the sensor does not recognize the print, but pressing down does work 9/10 times for me.
Not sure what's going on here...

My thumb works 10% of the time...my index 90%
Miss my HTC U11's home button fingerprint reader...

I've doubled up on the finger prints and it works slightly faster

I'm not really having any issues. It's not 100% accurate but is actually better than my Galaxy s9 one was

I have the same result. I find if my finger is perfectly straight and lightly pressing the screen seems to work best.

That is 100% wrong, I have the s9 plus my GF have the s9, never had a issue with either phones, the Lg is on a daily basis. I doubled up on the scan but same thing, the LG G8X finger print sensor is crap among other things.

It works perfectly if you do exactly what's stated in the OP.

You're joking right, this is my 6th phone with a finger print sensor, first with a sensor in the screen but that does not change anything. The Lg finger print sensor sucks, I'm not sure what you're trying to defend, it is what it is and yes I tried what the OP the first day I got the phone, including adding the same finger 4 times but it was no better than 3x, compared to the S9's the LG G8X sensor is trash.

Goodbye troll, have a nice day.

Gonna have to agree that the fingerprint sensor on this works better than my Note 10+. It isn't quite Note 9 accurate but after factory reset and sensor test, it works extremely well for me.

Try this:
Program the same finger more than once..
Mine works instantly 100% of the time even at 1% battery typing this now. It doesn't matter what angle or position. Program each finger the way you hold/want to unlock the phone.
And turn up the screen sensitivity esp if using a screen protector.
I came from a v30+ and thought i'd miss the button on the back. Just takes some getting used to.

Fingerprint scanner any better??

Please tell me it's better than the Note 4.? If anyone has used the iPhone 5s/6, is it very similar?

It work almost exactly as my iphone 6 Plus. Except it will ask you to cover the whole button...You don't have to most of the time, but works better when you do.

iPhone? Apple product?
...Burn the heretic!
On a more serious note, and as for the OP's question, pretty much every review mentions the fingerprint scanner being better, so no worries.
For some reason, the earlier reviews stated the S6 scanner was faster and more accurate than the i6 version, but the more recent ones are saying the opposite.

hm... this is slightly worrying. If I have to reposition my finger a couple times, it's no better than swiping more than once, as is the case with the Note 4. Fingerprint scanner is one of those things that should just freaking work, or the function will be quickly discarded.
mine is blazing fast, its almost instant

Look up and watch a video on how to enroll your finger properly for it to work blazing fast.
Instantaneous. Works perfect here .
Instant here too. Sometimes I don't lay my finger. I just tap the home button and it unlocks. Works really well

It worked really well and really fast for me the couple dozen times I tried it. (Then I got it paired with my Android Watch and set up as a trusted device so I don't need to unlock any more.)
My S5 was iffy at best and had to mull it over for a few noticeable fractions of a second (usually before it asked me to swipe again).

Fingerprint sensor faulty (no case)?

I'm a field tech and a father so my fingers can be cut up n dirty with glitter on them. I'm afraid that's not it though.
Anyone else having problems with the fingerprint sensor? It works great for a day or two then only every once in a while down to having to reprogram out of annoyance.
I'm currently attempting one index finger x4. Had been using 2 index x2.

yes...same here...there are times in it works flawlessly and times when it doesn't register at all.
i feel like having the metal sides as part of the fingerprint sensor is making it difficult to use...with or without a case

FPR is working for me flawlessly 100% of the time without a case on it, with a case is working 50% of the time. If your FPR in your phone is not working without a case 100% of the time is probably a bad set of finger prints registered or a defective phone. Try to register your finger prints again and se if that works. Good luck.

how many times did you register 1 set of prints? i have my right index finger (2x) and my left one (1x)...are people doing each finger more than that to ensure that it registers from every possible angle?
i have also deleted it and did it a over a couple of days ago...still have issues...it works most of the time though...just doesn't work here and there
the times it doesn't work, i dont believe (but I could be wrong) that it has to do with the finger placement..its just like it decided this time you need to use the pin code instead...so it will just fail until it forces me to enter the pin
I find mine doesn't work nearly as well when my fingers are dry, or wrinkly when excessively wet.
Other than that, even with my case on, the scanner works 90% of the times. It usually doesn't work too when I make poor contact with the scanner.
When my fingers are wet it doesn't work. I'm pretty sure they aren't making it fail on purpose to put the code in. Make sure you place your finger at the same angle or close to it, as to when you recorded your prints.

I have the same finger recorded a few times and it tells me to retry every time I go to unlock. This is the worst FPR I've had on a device, but still keep it on and just keep retrying, hah.
Im just curious as to how are you guys scanning?
Mine works flawless with a rugged case and no mods (like the foil tape)to the case.
I've only had this phone since Thursday and i just did the FPS yesterday..
Heres how I do my FPS.
Click and Release Button
But leave finger over the FPS ... Works 100% since I got it figured out.
And I only have my left index finger registered...

Mine is working fine without a case, but I recently got the VERSUS case, and only managed to get it to unlocked successfully only from 1 position, with the finger vertically 90 degrees, and using the finger tip

Question Fingerprint reader tip

If your like me and have struggled with the reader try this method.
Place finger on read and slowly move it up.
Works for me everytime and merry Xmas to you all
Being required to do anything "slowly" isn't a tip. It's a bad reader, and Google needs to acknowledge it. Bad design and implementation on their part. That's it.
never had a problem with mine using the wiping forehead method for the enrolment. Slower than my Oneplus yes, but never failed

I have no problem with the fingerprint reader and I'm using a 3rd party screen protector on the display.
I just got the TOCOL screen protectors after having the phone for a few weeks. Once I put them on I redid my fingerprints for fun and it seems to work just as before. I didn't boost my sensitivity either.
Still no luck for me after adding the screen protector
Zero replies actually acknowledging the advice.
After trying this it seems to work!
I do:
Place
Move a few mm
Stop.
Works great!
I have a Zagg and am still not impressed but this is helping a lot!!

Try the Gadgetshieldz screen protector which I'm using for a month now, I have no issue with the fingerprint sensor as I mentioned before.
Oddly, while the reader is slower than the one on the back of my Pixel 2XL, I've had no problems with the reader at all unless I move my finger while it's trying to scan. When you guys set up your fingerprints did you follow the advice given and moved your finger so the scanner could scan different portions of the fingerprint during the setup?
Got a Spigen screen protector on and the right thumb is more hit and miss than the left thumb. Unlock rate is about 6/10 for left and 4/10 for the right thumb. They need to fix this issue, little things like this can get annoying. Came from FaceID which was instant no matter in day or total darkness.
I set my phone up straight out of the box and I haven't had a single issue with the fingerprint reader at all. Idk if it's my skin, how I place my thumb on the phone, etc.. I was honestly prepared to have it be awful from everything I've read but mine isn't

Tocol completely destroyed the ability of my FPR to recognize fingerprints, with or without sensitivity enhancement, with or without forehead fat, etc. But I do have very dry skin.
Thanks - tried and so far seems to improve pass rate....not 100% successful mind you.. Maybe I am moving the finger too much..

Question FingerPrint Reader Woes w/Whitestone Dome Glass

Sunday night updated to the Jan security update on the Pixel 6. Prior to that, the finger print reader was working (but barely). I got distracted and forgot to check how the fingerprint recognition was working. The next day, forgot completely about the update and installed the Whitestone dome protector (which went mostly good but I've got three small bubbles, but that's another story).
After installing the dome, they recommend retraining the reader. However, even after training with multiple fingers, the reader, very, very rarely works probably less than 1% of the time if even that. Any ideas what I could try to improve the accuracy? The January update seems to have improved accuracy for most people. I just wish I had tested out the January update more thoroughly before adding the screen protector.
I bought the Dome glass,too. After replace it with the old glass protection the fingerprint was worse than before.
I trained the new, but not better.
What helped for me was to train the FPS again with more pressure of the finger on the FPS. Now it's working almost like the old protection.

Do you have to apply more pressure when logging in also or just for the training?

I just installed the Whitestone Dome yesterday. My fingerprint seemed to work the same but I went ahead and did a retrain. I think it is still close to without it (WD) except for 1 finger. I had an issue with that same finger on my old OP6T. Good Luck.
I also installed yesterday Whitestone Dome, the fingerprint reader works just like before almost every time. I never had any problems with the FPR, it only failed when I lifted the thumb to early. I did not retrain my thumb, increased Touch sensivity is still disabled. I don't know if it matters, but 4 finger profiles are my thumb.

I tried doing 4 finger profiles of the thumb but that didn't help either.
Does anyone one know if training indoors, does lighting impact the accuracy of recognition?

There are few more if anyone wants to do a little research.

Question Fingerprint sensor - can this be THAT simple?

Hi all,
As many other Pixel 6 users I was struggling with FP sensor in inconsistency - failed unlocks mostly. I did worked a bit better without screen protector, but my personal experience tells me I need one, so the struggle continued.
Today I've made yet another attempt to re-scan my finger hoping to improve the experience and then I've noticed that the sensor seems to work way better if I place my finger 2-3 mm below what I would call centered over the icon on the screen.
No I wonder - is is just me + wishful thinking or maybe there is slight misaligned between the icon on the screen an actual position of the scanner. Any thoughts?
a.
Weirdly, it works on the bottom half of the FPS scanner icon, and not the top one, so it might be that the sensor is a little bellow the indicator
So it's not just me and my pixel. Nice
You should have posted in reddit instead
You might be right, but I don't use Reddit. Hope whoever might want to try this he would eventually find this thread.
It works well for me, you need to install certified only screen proyectors
Agreed, the FP issue is negligible without screen protector, it a slow yet solid scanner.
I've checked Google's list of certified screen protectors and pretty much all of these get some negative reviews from users. Not to mention all either not available or out of stock in EU.
Currently I'm using Spigen glass, not on the Google's list, but works fairly well.
As I wrote in my first post moving the finger slightly lower on the screen seems to help a lot.
Interesting observation about finger placement and sensor alignment. I'll definitely experiment with that.
I was cussing the fingerprint sensor up until March. It couldn't even enroll let alone unlock. Long, tedious story shortened... Since March after clean flashing the factory image the sensor improved a lot along with solving other screen related problems. My best enrollment results were with warm and clammy fingers from gripping a mug of hot coffee. As it is now only one finger out of four consistently unlocks, but that could just be me. Or placement. With that one finger I'm getting acceptable results with a cheap 9H screen protector (3-pack for $9) and default screen sensitivity. A screen protector 1-pack in the $25-40 range aint gonna happen.

I'm using my P6 without screen protector, and it is very slow and inaccurate for me. For reference, I'm coming from S21 and it's instantaneous and very precise.
What did it for me was that i ignored the instructions completely and did my own routine. for example, i never rolled my finger over the screen. instead i did both sides of the fingerprint just pressing multiple times and on slightly different angles.

I know it's a different technology, but it's been around for a while now, since S10 (2019) and it only got better with time, so i can't figure out how and why did google skip it for its supposed "the google phone flagship"

I agree, it is a bummer. For last few years I was mostly using IOS and got used to authentication being seamless. My last Android was Pixel 2 and I admit - I've missed the experience. FP sensor is giving me some hard time, but I'm super happy with my P6. It will stay with me for longer no doubt.
I did some more testing, retraining etc. and I feel my initial thoughts are not accurate. The reason why I believed the scanner is positioned slightly below the icon on the screen was most probably due to the part of my finger that got scanned the best.
It might be due to the security reasons Google mentioned on the blog, it might also be a smaller and less accurate scanner used in P6/P6P. The outcome stays the same - you need to be very precise while registering your finger print and train your muscle memory to place your finger accurately on the screen.
The scanner on the back of the phone like to the one in Pixel 5 is not only using different tech, but it also makes obvious to a user where to put the finger. Pixel 6 makes it a bit harder, but that's about it.
With a deliberate finger positioning and some practice you can be pretty happy with FP scanner on Pixel 6.
Hi. I got a solution from this xda forum (sorry I don't have the link) but it basically resolved my fingerprint hit-miss issue. Ideally it involved:
1. Remove all the fingerprint images 8 previously made and starting afresh.
2. After removing, before registering new finger prints, first rub the thumb / finger I wanted to register on my forehead so that it collects a good amount of face-oil. Apparently the fingerprint registers well when registering the finger with an oily finger (I refer to the face oil...I have no evidence that other oils work).
3. After a good rub of the finger on your face you now go about registering the finger(s). Suggestion is to register each finger at least 2 times.
When you try using the fingerprint scanner it will work well. You may have to press in a bit (not so much) but this works pretty well.
