Questions about CM13's occasionally-working fingerprint scanner - Xiaomi Mi 5s Questions & Answers

Update: the problem was solved after I've disabled the lock screen widget.
Hi everyone! I’ve recently flashed the CM13 for mi5s which runs very well. However, I can’t always use the fingerprint scanner to unlock the phone. At the bottom of the lock screen it always (95%) shows the “key lock icon” so I can only unlock with PIN. But ironically, the “fingerprint icon” sometimes (5%) appears in the lock screen, allowing me to unlock with the fingerprint scanner. Does anyone have the same experience? How can it be fixed?
Thanks!

How did you set it up? I added it during initial phone set up.

At first I set it up during initial phone set up too (with two fingerprints), but then the problem arose, so I deleted the fingerprints and set it up again, but the problem is still there. Do u have the same problem? and how many fingerprints did you input?

[problem] CM11 Black screen ISSUE {c1905}

Hello everyone. I've just installed few CM11-based roms (MIUI and AOKP) and noticed a strange thing. When I am just locking my phone and trying to unlock it after a while, screen doen's wake up. It just stays black and there is no reaction for power button. I have to reboot my phone by removing battery so that is really annoying. Stock was working fine, i hadn't notice anything like that. Anyone know the solution?

Violently press the button over and over. It worked for me.
Sent from my awfully named device.

I found another solution i think. I just set up minimal CPU freq. over 400mhz and it's working fine. At least under the charger. You have to press it every single time or once and it's working fine then?
E: Without charger the same issue. Not solved.
I have the same problem and I think it has something to do with the proximity sensor.
Sounds interesting. Why do you think so?
Btw. I don't know why but I am happy that I am not alone with this problem.
Because:
Proximity Wake-Up support – prevent accidental wake-up of device by checking to see if proximity sensor is blocked (eg. Device is in a bag or pocket).

I think, here is some XPM bug. Just my thought

Screen Lock options unavailable...

Updated to Lollipop then played around with fingerprint screen lock and some other settings... Now I can't select any of the less secure methods for screen unlock. Anyone encounter this or familiar with settings to bring back all the options? Specifically swipe.
I had a similar problem with my s4 in the past. If I remember, I corrected the problem by clearing certificates in security.

Question No fingerprint option in settings after software update

Hello. I have this phone Mi 11 Lite 4g version. After i did software update to MIUI 13.0.7 Global Stable, fingerprint option gone in settings, and sometimes i have to click power button twice to turn off the screen. Any here have similar issues?
I have the same problem. After a while it showed up randomly in settings. So it rarely works. I hope it will be fixed with the next update. MIUI 13.0.7
This is a hardware problem. You should repair it in a workshop.
I had the same exact problem, turns out to be a hardware problem. As it was under warranty, I send it back and it was repaired. Good luck!
Same problem with me too, fingerprint sensor replaced by Xiaomi.
This is weird. I once woke up on a non-working fingerprint sensor. Although the option was still available in phone settings (I had 2 registered fingerprints), I couldn't register any new fingerprint.
That was like a nightmare to me, later on, I discovered it was caused by the missing property line:
Code:
ro.vendor.extension_library=libqti-perfd-client.so
Adding that line and rebooting fixed my situation.

Yes. You probably need to go to a service center.

Question Apps opening automatically when phone in pocket

Most of the times when I unlock my phone after pulling it out of my pocket some apps are opened automatically. I mostly see battery setting, Camera, weather and messages apps. Does this means my phone is hacked or is there any other possibility also?
If it is hacked, is the factory reset only option to fix it or there is any other option also?
It is most likely an issue with pocket mode. Pocket mode on F3 is just terrible. It could have happend that you touched the fp slightly while putting the phone in your pocket, it unlocked and accidental touches were made. It happens to me quite often and it is annoying. Try putting the phone display facing away from your leg in your pocket and see if that helps.
I had the same problem, when you put in your pocket, it unlocks when your finger touch the sensor... In the Settings for Security/FingerPrint unlock, select the fingerprint sensor unlock to "push" instead of "touch".
Thanks for the reply guys. Looks like @Magister54 trick worked. I havent seen that issue in past 2 days.

It is not available. And for some reason, there is apparently no ROM with this feature except MIUI.

Ah ok. Thanks
On crdroid there is an option that only allows the finger print sensor to work when the screen is on.
Does anyone have a good solution to this? I'm getting a bit tired of pocketcalling people
The feature in MIUI where you have to push the fingerprint sensor instead of touch sound like something that could solve the problem. Or perhaps the crdroid option HewettBR mention.
Is there any other ROM with a solution?
I'm running ArrowOS now but guess I have to change to an other ROM...

Question So Installed the pixel experience 4-1-2023 update and now face unlock doesn't work anymore

It worked in the 4-11-2022 pixel experience gsi
It doesn't work for me either.
Is someone able to register fingerprint and unlock with it? On my a52s I get a timeout error when trying to set up my fingerprint and the whole screen gets really bright when registering fingerprint

I think almost everyone has that problem, and I think it's because of the fixed FOD.
