Fingerprint / Pin - Android Q&A, Help & Troubleshooting

My LOS 15.1 hasn't locked - no Pin, no Pattern.
So I would like to add fingerprint to have some security. But it works only together with a pin/pattern - at least I understand it like that.
So I give it a pin, added fingerprint.
Now I have a problem. While the device is still not asking for pin/fingerprint when open it - it asks when I want to change something in these security settings. But my dammned pin fails. I am 100% sure I used that one.
What can I do? Beside that I can't change security settings it seem I have full access.
And isn't it possible to unlock the device with just the fingerprint?

I could found a few answers by myself.
Don't know why my pin number fails, I reflash a backup and it was clean again.
The fingerprint just replaces a pattern/pin, that's why this is combined. Operating with just a fingerprint is not intended for some reasons.

[Q] How-to recover default SECURITY - LOCK SCREEN settings (make NO-PIN-required)?

Hi.
Very annoying... I've got properly root'ed SGS3, with stocked ROM.
Originally I have all available Security - Lock Screen settings interface which allows me to use it NON-protected Lock (so unlock by swipe with no PIN).
However I have installed corporate Root CA (Certification Authority) certificate in the device, also just standard stock settings interface under Security. It asked me that it will set security settings on Lock Screen to require PIN. I was so stupid to tell "Yes". It installed the certificate and indeed it made me to set PIN. But, because I am using WidgetLocker-drawn Lock Screen with sliders etc, it is awful that default ugly PIN-require unlock screen interfere with this.
I noticed that however I do not need this Root CA cert - because I removed it (also via regular settings under Security section), rebooted device and corporate e-mail works perfectly without Root CA added to the device.
I removed cert but it has NOT unlocked Security - Lock Screen settings back.
I checked under Certificates UI - my corporate Root CA cert is not there at all, so all original stock, but now I cannot set PIN-required OFF back as it was originally, all UI is locked telling me that it is limited by administrator, encryption policy or certificate store. How to UNLOCK it back to stock configuration??
I know bad methods very well of course (WIPE and FLASH), but what about lass bad methods? Because I did not touch anything beside regular stock settings UI so dream to expect there's good method of returning Security Settings/Profile to "LOW" or In-Secure back as it was on stock...
Big thanks.
SOLVED!
Settings - Security - Remove Credentials (at the certificate section).
Helps immediately. Lock settings UI get unlocked, swipe available again.
Sorry & thanks.

Users with encrypted phones, help please

From the online articles and the encryption description i was left with the impression that i will need to enter the password only on boot.
Well appears that once encrypted the only active unlock options become, face unlock, pin and password.
All take too long for my daily use, and since you don't have to use the encryption password for unlocking (the phone is decrypted on boot) but other options like face unlock, why we can't unlock with the normal slider screen or at least pattern unlock?
Is there a way to go around it and enable the slider unlock on an encrypted phone?
p.s.
i know that decreases the security, but knowing that if i lose my phone, chances are the battery will die before someone digs into it, and they will need to decrypt it then.... is enough for my needs.
what version of the os is it? and yes you can change it. you have to go into settings >>security>> and should give you the option to change it. you just have to disable encryption. worst comes to worst...FACTORY RESET
the idea is to change it and still be encrypted...
it's 4.1.1
I guess encryption is not that popular among android users?

Is pocophone encrypted by default?

Hi there..
I'm trying ti understand device encryption before i install a custom ROM on my poco. (Any links explaining how encryption works on android would be greatly appreciated)
My first question is whether the pocophone encryption is turned on by default.
Under the encryption settings, the "encrypt device using lock screen password" slider is set to off.
However, every time I reboot the phone, i am forced to enter the lock screen password as fingerprint and facial recognition do not work. I assumed that this is because encryption had been enabled on my phone by default. But then why is the slider set to off?

The option that you are talking about under encryption settings, is the same as "Android secure start up" on AOSP. If you enable this option, you need to enter your device password while you restart the phone. Or else your device won't even boot up (and you won't see the lockscreen) completely and you will be stuck. It's an extra layer of security on top of lockscreen password/pattern/pin. Now coming to your second question, it's a security feature on android where no other unlock methods will work except PIN/Password/Pattern after you restart the device everytime. And it has nothing to do with encryption or decryption. Even if you decrypt the ROM, you will still have to enter your password or pin or pattern on every reboot. Only then all other unlock methods will start working. Some ROMs have a feature where you can bypass this security and unlock the device straight away on every reboot without entering the default pin or password/pattern. But they also put a disclaimer that it's not safe.
Thanks for the info.. But one of the questions "Is the Pocophone F1" encrypted by default?" is not yet answered. I am very interested to know. And (while I am asking) if not, "How can I do encrypt it"?
Yes, it is encrypted by default.

Problem with pattern lock: phone immediately relocks

On one of my Axon phones the pattern lock is broken:
If I enter a wrong pattern, then it says "wrong pattern".
If I enter a correct pattern, then it seemingly unlocks, but then immediately relocks.
If I use my fingerprint, then I can unlock and use the phone as normal, except:
I can't change the pattern lock. If I try to remove it, replace it with another locking mechanism (e.g. PIN) or try to change the pattern, then android asks me to input the pattern first and I get a very similar behaviour there too. Wrong pattern -> "wrong pattern". Correct pattern. -> It loads something and then throws me back to where I was before. And then asks for the pattern again.
This is very annoying, how can I deal with that?
PS: No root or anything like that, it's all stock.

Question How can i Unlock the device using fingerprint for the first unlock after restart without pattern.

Hi. After restarting the device, it wants us to pattern unlock for the first time. (Eventho i have fingerprint, it wont accept it). Why all roms want tis kind of method as first unlock after the restart. Just curious to know tat is there any method to bypass this.
Fingerprint unlocking is not as reliable as gesture or password unlocking.
So if the fingerprint scan fails, you may never be able to get into your phone again.
Therefore, more reliable identification is required for triggering.
If it can be bypassed, then it doesn't even have to be there.
You can use taichi module and customiuiser from playstore
