Fingerprint scanner and Camera probrems on CM13

Hi!
My phone has problem with CM13, so I tried many roms and so on.
Finally I knew that,
If I flash Radon-V2.8 with choosing FPC, Camera works but Fingerprint scanner die.
If I flash Radon-V2.8 with choosing Goodix, Fingerprint scanner works but Camera die.
Now I use cm-13.0-20160902-UNOFFICIAL-kenzo.zip and be in such situation.
Is there someone in same situation? and how can I solve this problem:crying:?

Fingerprint stopped working

Hi there,
All off the sudden, my fingerprint scanner stopped working. The problem is not that it doesn't recognise my finger, it's not working at all. Anyone having/had the same problem and maybe have a solution?
Thanks in advance,
Martin
I never got mine to work in the first place. It'll scan my finger but it won't ever recognise it as correct.
I use my fingerprint scanner without issues (in fact it's my new basic requirement if I need a new phone, wouldn't want to be without it). Have you tried to remove your fingerprints and add them again?
Yeah, I did try to remove them but it didn't help. Did a factory reset, but to no prevail. So I send it back for repairs

Fingerprint sensor problem

My MediaPad M5 (SHT-W09) has worked up well until yesterday. Now the fingerprint sensor is not working. I have rebooted, turned off & restarted it. I think the sensor MAy have worked again for a very short way but it is definitely does not work now.
The sensor does not work at logon, does not work for my banking apps and is not seen by other apps.Some apps say that there is no fingerprint sensor.
Has an app or something captured the sensor? If so how do I determine what is "hogging" the sensor?
Or is the sensor no longer working? Is so, is there any way to fix it?

Has anyone had the fingerprint sensor fail?

I also have the exact same problem.
It began a couple of months ago. The fingerprint sensor would show up for a couple of minutes after a reboot, but now it has disappeared permanently. Even the settings app won't show it after a restart.
Have you found a solution or some insights that could help us debug this?
I tried clearing the cache and sometimes it works for a while then the problem would reoccur. I did a reset to factory and this fixed the problem for a while.
I did cut back the number of apps.
Now it works perfectly and I don't know what caused the issue! It may have been a stray app.
Sorry about not giving a definite answer.
Chris
I have the mediapad m5 lite and I am having the same problem. It was complaining that the fingerprint hardware wasn't working and I restarted and now it is unaware it exists, even in settings. What was the cache you cleared? Did you have any luck further discovering what the cause is?
The fingerprint sensor works well now.
As I said previously, it must have been an app but I have no idea what
Sorry
Stay safe

Fingerprint issue with toast showing 0x1021

Folks,
I just got a new poco f1 128 GB. When setting up Dashlane I noticed the phone wouldn't recognize the fingerprint when enabling the capability of unlocking the app with it and a toast showed what appears to be an error (the toast just says 0x1021 over and over and over again so it's possible the fingerprint reader is getting disabled after many _fake_ failed scanning attempts). After this, the fingerprint reader stops working until the phone is rebooted. No difference after updating to MIUI 10.1 (Pie).
Anyone else having this? Any way to fix it? Not being able to log into apps using the fingerprint massively sucks.
Cheers

Try factory reset, and if it's not working, contact your vendor and use your guaranty.
Same problem here. The strange thing is, that other apps (e.g. Ethos) don't have any problems with the fingerprint sensor. Hence I guess it's a Dashlane problem. BTW: my phone is a Xiaomi Mi 8 Lite ... but it's a Xiaomi with MIUI.
same here, only with Dashlane. Redmi Note 6 Pro
