Fingerprint no configured turn on the screen - Xiaomi Redmi Note 3 Questions & Answers

My Redmi Note 3 Kate have no screen lock or password configured.
Im using global beta 8.4.19; magisk, twrp.
Its okay for me FP turn on the screen, didnt know it can work like that.
I didnt set anything and I cant find anything to turn off that, I mean, just touching the FP circle, it turns on the screen with any finger or skin contact.
How can I turn off that?

Unable to use fingerprint sometimes on lock screen

Hey so my v10 sometimes doesn't allow me to unlock my phone with my fingerprint and I have to manually enter my password. Is this a problem for anyone else or just me? I have changed the fingerprints and changed lock screen from knock code to pattern but neither helped.
Yes I get this too. I know it will force manual entry after reboot but I experience this throughout the day from time to time. Its inconsistent.
Do you use an app to put the phone to sleep? There is a known issue in Marshmallow where fingerprint unlock will not work if the phone is put to sleep via an app rather than the power button.
I do double tap the status sometimes to turn the screen off but I don't think it's that. And no I don't use an app to turn off the screen

Fingerprint sensor acts like unlock button

Hi guys,
I have received an update lately (MIUI Gloval 8.1 Stable - 8.1.1.0) and my struggle began. My problem is that now every time if I touch the fingerprint sensor the phone unlocks. It's REALLY annoying guys. Sometimes I lock my phone and put it down and the screen unlocks because accidently I touched it. Fingerprint is disabled, furthermore I have no lockscreen whatsoever have enabled. The fingerprint sensor at the back acts exactly like the unlock button on the side. How the hell can I disable this annoying function?
Thanks !!!
Settings - Lock Screen & Password - Manage Fingerprints - Enter Password if you have one - Apply Fingerprint to Lock Screen - choose disable?
Fingerprint wakes up the device if u haven't added any fingerprints.
That's a thing in marshmallow MIUI (even on the beta builds), it's not a bug, tapping on fp without any registered FPs wakes up the screen.
Furthermore, u said that there's 'NO LOCKSCREEN' you kept(so i assume there's neither swipe to unlock screen) so fp is waking your device everytime,and consequently,screen gets unlocked.
I see. Any way to completely disable this function? I dont want that sensor to work at all.
Me too, I have the same problem, the fp sensor wakes up the screen when I'm touching it accidentally most of the time. How can we disable this annoying "feature"?

Fingerprint not working in redmi note 4 after back Miui

After using custom rom decided to come back Miui 8 global 7.2.9 beta
My fingerprint sensor does not recognize any fingers
First vibrates then go to lock, pin, or pattern sometime it's goes straight to pin or pattern screen without vibration
It's really annoying me. Any solution often
Off screen lock don't delete fingerprint
Again on screen lock add fingerprint
It doesn't work me?
Waiting for solutions Any suggestions

Restore or flash fastboot?
Have you upraded the Bootloader? The Radio? Is the Rom (that older Rom) compatible with the Bootloader Version? Check it and write back

Did you try this : Screen lock > Register unrecognized finger
and add patern/pin
then go to settings
and don't delete the fingerprints
but remove the screen lock itself
and then add screen lock and register fingerprint

Go to twrp. Then enter file manager. Navigate to /data/system/. Now delete the following files:
password.key
pattern.key
locksettings.db
locksettings.db-shm
locksettings.db-wal
This will clear all saved pattern/pin/fingerprints.
You can boot into your system and set them again.

Question Fingerprint doesn't work properly when screen is locked

Hello,
I have problem with my Nord2 - Fingerprint doesn't work on always on display unless screen is tapped once or phone is picked up.
If always on display is off - same problem. I think there is problem when screen is locked.
Yeah it's a normal behaviour of most of the phones with AOD and with fingerprint scanner under display.
The screen needs to illuminate where you place your finger in order for the fingerprint scanner to be able to read it from below the screen and the AOD don't have this possibility (it would consume to much battery to have this zone always illuminated)
You need to tap screen or pick the phone up to switch from the AOD animation to the FIngerprint animation and be able to unlock your phone.

No. It's not a normal behaviour.
Moreover, with the very initial build it was good.
Accessible always. But 1st update had few chances related to fp which broke it from aod.
Sorry I didn't meant to be rude.
I received my Oneplus Nord 2 phone with the A.05 update and already back there the AOD didn't have the possibility to scan the fingerprint . I have a colleague with the Oneplus 9 and asked him how is the behaviour of the AOD on his phone and same thing : his phone doesn't unlock when you press finger in the AOD. You need to single tap once to bring the fingerprint icon online and only after that you can unlock the phone in the AOD screen
The only thing you can do in the OxygenOS AOD settings is toggle the
"Fingerprint icon - Show fingerprint icon temporarily when the ambient display is shown" option .
Will be able to unlock the phone in AOD mode for a few seconds only after you lock the phone, after that the fingerprint icon disappear and the digitizer turn off to save battery .

Question Fingerprint sensor

I don't know anything about how under-screen fp readers work, but... Is there no way to use it when the screen is off?
On previous phones I always used the fingerprint sensor to turn on and unlock with one touch, but this N20 5G seems to only fp-unlock when A) The screen is on, and B) The "fingerprint goes here" icon is visible.
The screen will usually turn on when I pick up the phone ("Somatic Gesture"); the fingerprint icon then appears for a few seconds, then goes away. That seems to be the only window for unlocking without clicking the power button.
Am I missing a trick?
I use double tap to wake and it works great. The sensor stays lit up for about 7 full seconds before going black. YMMV
Good point, double-tap to wake was disabled by default!
Still two more taps than I'd prefer to get to the fingerprint unlock, but I guess that's more a reflection of how incredibly lazy I've become than a problem with the phone.
