MIUI screenlock with fingerprint from standby - Xiaomi Redmi Note 4 Questions & Answers

Cheers,
on current official MIUI stable I occasionally get the experience that by using my fingerprint I don't always unlock the screen but merely wake it up and have to basically do a "double tap" to unlock. Yet other times it immediately unlocks from a sleeping screen.
Just curious on where to debug this issue and explain the behavior from.

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"?

[Q] Screen Lock/Off without Root

Hi All,
i have an unrooted Pixel XL (Damn Verizon...)
i want to be able to turn the screen off with a gesture, and use the fingerprint to turn it on. however, if i turn it off without the button, pressing the fingerprint says the device is "locked by admin" and i need to insert the pattern.
the only way around this is to use an app that makes the screen go black for 10 seconds.
any way to shorten that time or even better, do it for real without root?
thanks guys.
IIRC, one will be forced to enter the code/pattern every 48 hours or so if fingerscanner is enabled. Probably to increase security and prevent you from forgetting the code after one year of never having to input it.
This behaviour will also be invoked if the fingerprint is misread 4-5 times in a row, or if the phone is locked/turned off with any other means than the power button or screen timeout.
So if an app locks the phone, you will have to enter the code to unlock it regardless if fingerprint is enabled or not.
Some roms support turning the phone off when tapping 2 or 3 times on the home button.

Screenwake on fingerprint

Hi guys! Noticed that my pocophone's screen wakes up whenever I touch the fingerprint sensor. I didn't enable the fingerprint authentication nor enable any security unlock(pin, pattern or password)
But the screen keeps on waking up whenever i touch the fingerprint sensor. I just want to disable this feature as it keeps on turning on while on my pocket.
It turns on even with pocket mode enabled.
Can be disabled in custom ROMs, not so in MIUI

Chaire! I tried doing so in MIUI but failed. I believe that there maybe an option to disable that in custom ROMs.

Hi! What particular custom rom is it? This is just a new phone. I'll have to wait for a few days before I can unlock it.
If no fingerprint is setup, it will wake the screen with slight touch. If you set the fingerprint, it will not wake the screen in the pocket. Probably better if you just set the fingerprint and use the face unlock as it unlock the screen so fast even in the dark.

Chaire! LineageOS Extended 15.1 allows for completely disabling FP if you do not use it. But is it worth going to these lengths for such a small feature?

Chaire! This is one the very good solutions!

Fingerprint Bug: Not waking up Honor 9 - STF most of the time after a while in sleep

I recently upgraded from 9.0.0.179 to 9.1.0.210, and now my fingerprint reader almost never wakes up and unlocks the phone instantaneously like it used to. If the phone has been in sleep for atleast a couple hours, it doesn't work. I have to first turn on the screen with the hardware buttons. If the phone was recently used, just putting my finger/thumb on the reader can wake and unlock the phone, but it takes 4-5 seconds of pressing the print on the reader to have the screen turn on. The screen only instantaneously wakes up and unlocks if the phone was used in the past few minutes.
Has anyone else had this problem? Does anyone know how to fix it?
Just an update in case anyone else experiences this in the future: I have found that if I tap the fingerprint scanner a few times, it will wake up the phone faster and even if in deep sleep.
