Suddenly, my fingerprint sensor stopped working. I can still use the home button by pressing it, but touching/swiping does not do anything.
Flashed this patch https://forum.xda-developers.com/lenovo-zuk-z2/themes/patch-fingerprint-fix-pie-t3833320 but it did not the trick. Dirty flashed AEX 6.6 (same as before), now the sensor "works." However, after some time I frequently end up with a message on the lockscreen which loosely translates to "no fingerprint sensor hardware found". In this case, I need to unlock the phone via PIN, sometimes the sensor is then back to normal
Any ideas what could cause the problem?

Could you be a little more precise?
So far, I have flashed ZUI and afterwards AEX 6.6. The problem sill persists.
I would highly appreciate some feedback.

HI, guys. You my only hope. 6 month ago a replaced my screen with screen from Ali. Sometimes I have problem, that after call touchscreen became unresponsive screen is working . Reboot with pwr + volume up do the job. I do some research. Proximity sensor is OK, even with disabled touch, thanks OTG cable.
Problem is unstable. O can't repeat it. Happens Suddenly.
This problem is rom independent. But I used only stock, and now on stock based custom
Locked bootloader
anyone? =(

i have the exact same problem with you and i think is screen related.
i ll perform the proximity sensor check and if it is not the source of the problem,i ll take off my screen,give a cleaning at the connections and put it back on, to notice it s behaviour.
hope i won t break my screen cause it happened before:fingers-crossed:
my screen has started un gluing from the left side of the display and screen is lifted upwards ,i just mention this for the possibility of causing a problem with those freezes during incoming calls,but i can t think of anything.
probably i need to order a new display(not from the same seller of course) cause it is a little dim too,if it s not fixed after trying those i really don t know what i will do with my phone,it really gives in my nerves with this problem(otherwise i m very satisfied of owning it).
i ll come back reporting after making my tests...
EDITroximity sensor check OK,no problem.
cleaned the connections of my screen and i have only 1 freeze after 40 calls,but is still there and is only a day that passed..
i can t target if my problem is hardware or software,i ll flash stock lollipop with flashtool and wait for some days,but if it appears again what should be my next step?
any ideas welcomed..
EDIT 2:after five days on stock 5.1,problem seems to dissapeared,so i supposed it is related to an app...
EDIT3:till now everything is OK.

I don't know is it a hardware problem but I guess your fingerprint was learn while cable was plug.
You can try to re-learn fingerprint without cable.
you can make sensor more precision by double or tripple 'add fingerprint' with the same finger.

Did you get any solution?

(UPDATED)
Hi, when i try the code *#2663# only said DeviceKeystring has stopped.
Yes, my note only works with the SPen, but i want to try with that menu to see if it can made that the touchscreen works again or not, but i have the problem that i said.
I'm in the N920AUCU5ERB5 system.
I tried with the Binary System 5 and it made the same error.
Could it be that the touchscreen it's really broken?
New Information
Hello, this morning when I woke up I took my cell phone and I did not take it well and it fell to the floor, nothing was broken, so I decided to restart it to see what happened, when I did the touch screen was working.
I'm not saying that if the touch screen does not work, drop your cell phone NO, but it is likely that if this is failing have to open the cell phone disconnect and reconnect the cable that connects to the screen, maybe work as in my case although it was unexpected.
And yes, the *#2663# is working now, but how the touchscreen is working i don't going to update that.
Unfortunately during opening I cut original flex from fingerprint sensor, till that time everything worked well. I ordered 2 brand new sensors and simply replaced, I've tried both sensors but non of them is now detected by the phone. I did full wipe, reinstall firmware (official downgrade) but fingerprint is simply not detected even in test mode. Any ideas how to make it work again?
Hi all!
I cannot configure the fingerprint sensor, when I press any finger, it only vibrates, but it tells me that it may be dirty, which is not the case ... any idea what it may be?
I tell you that I tried with the official Android 9 ROM of my model and country (Argentina) and it does not work either. Now I put Android 10 (Canada) and it doesn't work either.
Please help!
Thank you,
Dreamer.-

This happened for me when I broke the back panel.
If you press on the reader and it works, that means there is a lose connection. You will have to fix the back panel.

My V40 did the same, so I had to send it in for warranty repairs. It was a hardware issue for me.
I already resolved it! The solution was to flash it to version 8 of Android, which was the one with which the cell phone came and then I flashed it again to version 10 of Android and the problem was solved !!
