as title says. it only works when i turn off the screen.. whats happening?
What is software build is your S20FE on (Settings > About Phone > Software Information > Build Number (last 4 characters))
Can you be more clear on this "issue"? The fingerprint reader is supposed to only work when the screen is on, since the reader is on the screen itself
build CUE3.
i have to turn the screen off with the power button to get the fingerprint scanner to work. it will light up under the thumb and unlock.
but it will not work when the screen is on. when the lockscreen is lit, or some app wants to use the fingerprint for authentication.
flash your firmware again. or you could try turning it off completely, rebooting and adding prints again.

how i could unlock the device with fingerprint while the screen turned off ??
is there a way or thirdparty tool ?
thanks in advance
The device cannot leave the fingerprint scanner always connected to its power, so it's not possible.
Android leaves/sets its power off when the screen is off.
To unlock the device "while the screen is off" to be ready to use it: put your finger over the button and then press it without release the finger from it (but obliviously release the button" click"). In this way the screen will turn on and in few milliseconds it will be unlocked.
you can download always on display app in google play store and on this active the home button.
then when your device is on always on display you can use finger print sensor.
I hit the fingerprint sensor every time I take it out or put it in my pocket and that triggers the screen to turn on.
I don't really need the sensor, but I haven't seen a way to disable it in any of the settings?
I would like to the same thing, I dont really need the sensor active
Settings; lock screen & password; screen lock & fingerprint. You'll turn off your fingerprint reader and lock screen from here. Be sure all your fingerprints are deleted.
There are no method to turn off the fingerprint sensor at the moment, the above method just remove the fingerprint but screen would still be turn on when press on sensor, which is an issue for me also.
If this is really bothering you, stick a sticker on top xD
sticker? that's what I was thinking of.
I have my phone set to lock when I turn the screen off with the power button. After updating to 9.0.6 I can just swipe up on the lockscreen without showing my face or touching the fingerprint sensor. About 25% of the time it also shows my home screen under the lockscreen before unlocking.
Oh nevermind, it's was smartlock keeping the phone unlocked. Sorry. Pls delete
This reminds me of the time I thought the finger print reader was working through my gloves. Turns out it was face unlock barly seeing me at the edge of it's field of view
Ever since I bought my 9PV, I've struggled with it's lousy fingerprint scanner. Compared to my previous Nokia 7 Plus and 8.1, the scanner is from an entirely different universe.
When testing the scanner, it usually performs reasonably well (provided that you press down your finger somewhat hard), but that's only if you lock the phone using the power button and then immediately wake it up again and then use the FP scanner.
If the phone is left alone for a while, that's when the problems begin. The scanner doesn't seem to wake up from sleep at all. The green scanning light doesn't come on. If you move your finger over the scanning area a bit, it might wake up (and then of course do a misread because of the finger moving). It got to the point I learned a new way of using the FP scanner: I place my finger about 5 millimeters "too high" and then slide it down to the right position. This way I got it to wake up somewhat better, but far from perfect.
So my problems were mostly because the scanner doesn't wake up at all. When it does wake up (the green scanning light comes on), it usually works fairly well.
I reported my findings to HMD support and got the following suggestion:
I would like to suggest the following steps in attempt to fix your issue. Follow the path below:
• Set a screen lock from Settings -> Security & Location -> Screen lock.
• Open Settings -> Security & Location -> Trust agents -> Smart lock ->Toggle off Smart Lock to disable.
• Restart the device.
• Open Settings -> Security & Location -> Trust agents -> Smart lock -> Toggle on Smart Lock to enable.
• Open Settings -> Security & Location -> Smart lock -> Set up a Smart lock.
• Restart the device & test the fingerprint.
Also I would like to suggest adding the same fingerprint from the finger few times.

So it seems Google's Smart Lock agent somehow interferes with the FP scanner, causing it to not wake up. I don't know why and how. I did as the support suggested and it indeed seems to wake up better than before. Then I disabled Smart lock altogether (in the Trust agents menu) and that seemed to make it even better. The green scanning light comes on every time.
Those of you with similar problems might want to try this method, and please report back. Give it at least a few hours, or perhaps days, to get a reliable result and then report back. The phone must be sleeping, so it has to be lying idle for some time in between every try.
Anyone know if there's a way to disable the fingerprint scanner activating any time I pick up the phone now? Never did that before the update, it's pretty annoying. Already have lift to wake turned off, but that doesn't fix it. Went through every setting and didn't see a way to fix it. And it's not the lift to wake option, the whole screen doesn't turn on, just the fingerprint scanner and icon. Seems to be making my battery life way worse.

Because Blu cust support has not duplicated it, others with update didn't duplicate it.
Makes it seem like just your phone.
Did you try to factory reset it.
Fully. Remove saved fingerprint remove accounts,
Reboot to recovery and do factory reset. Setup phone again

Late reply I know but I found out how to disable this option.
In the settings go to:
Display->Ambient Display
Turn off the option for New Notifications.
I have no idea why it is called this as new notifications (SMS at least from my quick test) still wake the screen,but the fingerprint sensor no longer shows when you lift or move your phone. Completely mislabeled but hey at least you can turn it off.
