I have been facing failure in unlocking the device with intelligent scanner both face and iris unlock not functioning properly.1 out of 5 tries works and if it works then it's really really slow, I felt my previous phone one plus did a great job with face unlock.I have removed and re-added face and iris data like almost 5th time now in different lighting condition.
Please help me the solution if you had the same issue. Should I contact Samsung for replacement or just move on with the issue.

Had my S8 plus for about a month now. Every 2-3 days or so, the fingerprint sensor stops working just randomly. Will work perfectly, then just out of nowhere, doesn't respond to anything. Disabling fingerprint security and re-enabling doesn't fix it. Trying to go into applications- system apps- fingerprints, and trying to force close it won't work as it's grayed out. The only thing that works to get it working again is a restart. Not the end of the world I know, but having to restart it at the most inopportune times is kind of annoying. And paying this much for what amounts to the top of the line phone on the market right now, and having one the most important functions just stop working all the time is crap. And no I don't want to use the iris scanner, or pin, or pattern security. I want to use the fingerprint sensor.
Searches around the web indicate this is pretty common. Anyone else on the VZW S8 or plus having this issue? Anyone know if a fix is coming down the pipeline? I'm pretty sure this would be a software issue as it works 85% of the time and a simple restart gets it working again.

Some other threads on XDA have said that disabling fingerprint scanner gestures fixes it. I haven't ever used those and I have never had a problem with the sensor. It isn't as good as the sensor on my Moto Z Force Droid was, but it is pretty good.

Yeah, I disabled that last night. Waiting to see if that works or not. Just thought I would post in the Verizon specific forum to see if any other Verizon users are having this issue. Pretty sure it's a software issue, and am just curious about differences between the Verizon software and other carrier specific software.
Always had the gestures disabled and I have noticed this, but it always goes away with time for me. I thought it was just because I was sweaty at the gym, but it doesn't even know that I am attempting to use the scanner. Then, it happened outside the gym. Goes away in just a couple minutes, thought it was just me.
It seems that the fingerprint scanner is more reliable when the screen is off than it is when the lockscreen is on looking for iris scan.
Hi,
Using the Red Magic 3 is quite nice, but one of the major problems to me is the FingerPrint scanner.
It happens really often that I have to "press" the FP scanner several times before it lets me in
But on the other had, Face unlcok works superbly here !
It recognizes my face everytime, even in rather dark environment.
And unlocking is then super fast...
Guess I'll use that more often than the FP scanner
You guys also have that "problem" with the P scanner ?
No its working perfect for me, much better then the fp sensor of the xiaomi mi mix 2 (my prev phone). Meaby try to set it up again?
I had the same problem, then it went away, then it came back.
Saw some people complaining here as well on github.
Funny thing for me, seem to be related to having activated multiple users in this device and for some reason the finger print only works (normally) on this second account. Deleting that saving account did not solve the issue as the sensor continues completely irresponsive in my main account (so it's clearly just a software issue). If I recreate a second account it will work there, but still not in my main account.
Do you have more than one user registered for that device? I use the other users mainly to have alt accounts for different games
I'm in touch with their (slow) support and the last message I got was:
We will feedback this case to our R&D .Pls provide the order number and Build number of the phone.If you can, please also provide a video file of this process,thanks.
In my case it's clearly just a software issue, so it should be fixed in future builds (hopefully).
Perhaps a factory reset would help, but I don't want to test that option as I'm lazy to set up everything up again.
Hi,
Same thing here.
The FP scanner is not on par with some of the RM3 sibblings like the Mate 20x or the mi mix 3.
I think the scanner is too small to recognize your fingerprint decently.
But if I compare Face unlock on this device to face unlock on the afroementioned devices, it's a totally different story !!!
It is amazingly fast and reliable, even in low light conditions...
So I am almost always using that one.
Regards.
No problems here with the FP scanner.
I'm on Global ROM,bootloader is still locked,no root and only my account registered to the phone,but I've setup 4 fingerprints,and all of them work quite good....
On my Mi 9T Pro, face unlocking has been very problematic, as I found out that my brother can also unlock my phone. This obviously does not speak to the face unlock's security, as I do not even look that alike to him. When I tried re-adding my face several times it continued to have the same problem, even when I went outside in the bright light to set it up, my brother could still unlock it. I have since disabled it as this likely means it is unlock-able to anyone with a similar face or even a piece of paper.
This is the case with all camera based face unlocking.
Not really, have tried the same with galaxy s8 camera face unlocking, and it doesn't have this issue. I don't think this should have been put in this phone if it as insecure as it seems.

Well there are some differences. Here and many phones are only using a cheap 2d image recognition method, which i would say is mostly only an unsecure gimmick.
additional security would use 2 cameras for a 3d face recognition. Still not as good as a fingerprint lock, but already pretty robust.
with an extra infrared projector it is also possible to recognize faces in the dark or in too bright places for regular camera images.
Here is a more indepth explanation

Wonder why is this not yet raised while all devices I have tested has the same critical issues of unreliable Fingerprint sensor and VoLTE as below:
1. Fingerprint sensor randomly stops responding for several seconds when an app or phone needs to authenticate. Sensor itself is working as other gesture controls work fine. However the authentication API sleeps for several seconds to a minute or till the device is put on sleep and woken up
2. Dual VoLTE and Dual 4G cripples while giving false ringing on Airtel and loosing VoLTE symbol and connectivity on Jio. While other phones randomly loose signals, V40 does this false ringing on Airtel while there is no incoming or outgoing call connectivity without giving any error
Both these issues affect all 3 devices tested and factory reset, etc. Doesn't help either. Phone was never rooted or custom firmware installed (as I don't find any useful here)
Appreciate if someone can suggest a possible fix as I love the phone and except for this and random lockup due to choked RAM (0.5GB or less physical RAM available most of the times while also consuming all the 2.8GB swap file)
Both these issues are observed on the latest Android 9 upgrade for India (released on August 1st). I can confirm that Fingerprint sensor never caused any issues before this upgrade on any device. Have tested on several devices and have replicated these issues on 3 of them simultaneously
I'm having the same issue with my fingerprint sensor. It's annoying, to say the least, especially when I'm trying to unlock my phone in a hurry. I have my device for 3 months now, and it only started happening two weeks ago. I haven't received any updates since December, so it can't be a new update that caused this.
I've also done a hardware test, and it shows the fingerprint sensor is working as it should. [emoji2370]

Thing is android will have worst performance and than what operating system it came with when released other than software issues. This is the reason why people will try and want to downgrade their operating system back to how it came with.
I am also facing Volte issue with airtel, I don't find any solution yet, So i have disabled Volte for my airtel connection. I have noticed this volte issue is only happening from last year October, Before it used to work..
I have also noticed fingerprint sensor issue and it is very random.
Ive had the finger print reader issue, but noticed it had to do with my cover I use.I have a complete shell type case,and over time it collects residue around the edges of the case around the sensor.Removing the phone from the case,and the sensor works fine,sometimes I may have to clean the sensor with a damp cloth.
With my slim fit case,I never have the issue.
I've noticed something a bit odd regarding the fingerprint sensor. After I make or receive a WhatsApp call, my fingerprint sensor usually stops working for a bit. I haven't really had issues for the past week or two, until I received a WhatsApp call. Immediately after the call, my fingerprint sensor didn't work, so I unlocked my device with face unlock. After that, it worked perfectly fine again. And a few weeks ago, I made quite a few calls on WhatsApp, which is when I had constant issues with my fingerprint sensor. I even reset my fingerprint authorization app, and cleared my fingerprints from the device, to help sort it out.
I know it might be a long shot, but is it possible that there's a bug that causes this, either from WhatsApp or on the LG firmware itself?
If anyone has more knowledge about this, your input would be highly appreciated!

Hello Folks,
Coming from a S20 im finding the fingerprint scanner quite infuriating. has anyone fund a way to improve this?
Oh and sometimes it goes straight to the pin, not even an option to unlock. why?
Maybe (I doubt it) google will improve the fingerprint with software updates overtime. For now it's just totally unreliable. If you want to live with pixels you have to adapt I use smartlock (smartwatch) and thanks to that I don't need to use fingerprint at all (well almost, 2-3 times a day it asks for it).
I come from Samsung Galaxy Flip4 (S21 ultra before), I have Pixel 7 for 3 days and I have no problem with fingerprint.
Have you tried re-registering your fingers?
Its improved having the fingerprint registered twice. but for some reason you can only register 4 of them
