Question Fingerprint doesn't work after update MIUI 12.5 - Xiaomi Mi 11 Lite 5G

Hi
After update MIUI to 12.5, I normally use an application (screen off and lock) to lock the screen, since double tap doesn't work.
Turns out that after the update when I lock the screen through the app, I can't unlock with fingerprint saying that "device locked by admin" and I have to use the pin to unlock.
Anyone knows how to overcome this?
Thanks in advance.

Okay,updated our phone today and got exactly same problem as you..
This was not funny at all i have to say,my wife is absolutely crazy because of this issue and think´s the whole phone is ruined because of this,okay..
Isn´t it anyone out there who has a solution for this or do we really have to wait for another update to come before we can have the fingerprint to work again because i really hope they going to fix this for us or?

Same here on mi 10T

I have learned not to update MiUI, as the updates rarely fix old bugs and ALWAYS introduce new bugs. Best just sticking with what it came with until a custom ROM comes along and then leave the MiUI crap in the past.

Problem is 3rd app lock method.
Here is solution:

I use NOVA LAUNCHER and I have same problem after 12.5 update. So I changed LOCK method in NOVA and it works.

So easy but still so difficult to figure out...
This was really good to learn about i have to say,thank you very much for your help!

I solved this issue after updating my Mi Note 10 to MIUI 12.5.1 by switching from 3rd party screen lock / turn off app to an official built-in widget simply called "Lock" (go look for it, it should be near the top in Widgets section when you press and hold empty home screen area).
To remove unofficial screen lock app you must first revoke admin rights, of course, otherwise its ghost will keep reappearing after each uninstall attempt.
I simply like stock MIUI Launcher, so using 3rd party ones to solve this was unacceptable for me.

if u guys are just talking about turn off screen without using side button, then there are some options present in miui...
1) [if u r using button navigation] setting> additional setting> button shortcut> turn off screen> choose as ur choice
2) You can also use the quick ball, 'setting> additional setting> quick ball' with quick ball u can use 5 shortcuts like home, menu, lock, clear cache, ss etc
3) the widget option... Just like d789 said

---

And 'double tap to wake or turn off screen' option is present in the "setting> always on display & lock screen"...

---

Thanks, I overlooked that buttons shortcuts in Settings can be configured to lock the screen as well (e.g. long hold Back or Home on-screen button).
Yeah, double-tap to wake or turn off screen is also very useful feature I use since day 1.

For me this doesn't work.
I use Nova and always have.
In Nova I go to "Gesture and Inputs" change the "double tap" to "screen lock".
I then choose "Accessibility" and add Nova.
After that if I double click nothing happens. If I remove Nova from accessibility and then double tap it asks me to use device admin or accessibility. I use this way on every single mobile I use but on 12.5.3 I can't pick accessibility as it refuses to do anything when Nova is added.

Thanks, I didn't know about that.
Now the only thing for me that is still broken is the fact that I can't use gestures with Nova launcher.

To everyone who's still facing this issue. This fix helped me and a lot of others as well. Try it out.
It's a rare but annoying glitch in MIUI, you can easily solve it:
1. Go to TWRP -> File Manager
2. Browse to: /data/system
3. Delete file "locksettings.db"
4. Reboot.
You will need to set the lock screen password/pattern again, if you had any before.

That's a bit harsh. We have had Redmi 4 prime, 5 plus, note 7, 8, 10 and mi 11 lite and I have not had significant issues during upgrades.

Dear friend, my phone is Redmi Note 7 Pro. I had no issues after doing this. It worked perfectly for me. So, as I saw this forum thread before fixing my phone, I just shared the information I knew. Not everyone will get the same result from this, because not everyone has the same phone. So, whether or not you didn't get the expected outcome, you shouldn't tell others to not follow this. It's their choice, not yours. Maybe atleast some of them will find it useful than you did.

Thank you very much.
This works for my RN10Pro using MIUI13.0.6, change the lockscreen setting in Nova, from admin to accessibility.
I can't double tap to close home screen anymore, but there's still home button in the lowest middle to do that.
The most important thing is, I can directly go to home screen just by touch the fingerprint button.
Thanks for your advice.

If you guys are talking about the fingerprint button then i suggest you just use the gestures that are provided by default of the settings since there nust be a spatial consisting of failure of recognizing the algorithm of identifying user by fingerprint method or they just didn't implement the algorithm that is stored inside the operating system of the phone.
So gestures is the only way to go you can apply gestures by using monetary apps that may give access to other gestures like slide down to view user statistics or usage and slide up to reveal system settings but i couldn't blame the operating system though for having not enough gestures but I'm also. Thankful that they have custom gestures so i wouldn't imply to an app that can be placebo or popular in playstore who knows it can be money cashgrab(just stating the fact that i had to cancel so many subscription on a gesture app)
