Hello, well I have noticed recently a strange behavior in the fingerprint sensor, but this behavior its always there (its not recently)
I have a pattern and the fingerprint enabled, but the fingerprint sensor only works when ths lockscreen displays the fingerprint logo, but here is the strange thing, the sensor recognize my fingerprint (because it vibrates once and ask for the pattern, if I put another finger its not registered, vibrate twice and doesnt ask for the pattern), I have already flash the phone several times, the first time I believe the sensor just doesnt recognize me, but later I discover this behavior and it looks like maybe a software bug
Something else notice these?
Is there a fix? its sometimes annoying
Thanks!

maybe its a hardware issue , i think u said u flashed ur phone several times? tried different ftf files? if thats the case , then its hardware issue. i havent heared that at all. the only issue i have seen before with the fingrprnt scanner is that sometimes it says an error but u reboot and its ok ( havent seen that for months though)

yes I have flashed it several times with the original and other ftf files (always respecting the model number), will try with a friends phone and see if this behavior happen there too
Latest firmware of Nordic Combined hasn't given this issue for more than a month now. Do a clean update I'd say.
Charged phone during long flight, and read a lot. After landing, fingerprint sensor was like 50%. Reboot, no improvement. Menu for fingerprint settings...click and lag, nothing. Reboot. Now fingerprint menu is gone. So is home button!
PITA....got Leedrod tweaks for Navbar! Dirty flash, and no fp sensor. Clean flash, no fp sensor. Restore stock system and wipe data...doesn't even ask for fingerprint on setup. It's like the hardware disappeared. Tried force stop fingerprint software from settings, apps, show system, and clear data. Reboot again...gone.
Wakeup next day, reboot and it works? So flash Leedroid, and restore my Nandroid data...all good now.
So what can cause the loss of the hardware like this? Some kind of security lockout? Or hardware fault? Didn't get wet. Still in 30 day period...should I send it back?
Has there been a software update from htc for the fingerprint sensor?. Things usually go mental when updates occur..

No changes from my end regarding software. I guess it's possible something got corrupted with flashing and stuff. Seems to be a common problem on other devices:
https://forums.oneplus.net/threads/...vailable-issue-started-out-of-nowhere.450914/
They describe same situation as me. Hardware just disappears, and the related menus.
Thought mine was fixed, but it happened again last night. I let battery fully drain, then fully charged, rebooted, and it's back again? I did walk around in the rain last night...could be related.
Wish I knew if this was software or hardware issue. Guess only way to know would be to RUU.
Another weird thing: I have to enter a pin now when phone boots up. Not on the lock screen, but on a separate system prompt. Same thing when I start TWRP. Could be a security issue? Or a conflict in PIN settings?
Any help appreciated!
There's already a thread about this https://forum.xda-developers.com/u11/help/home-button-fingerprint-sensor-stopped-t3632297 this is no hallucination, I experienced it myself, and also a lot of One Plus 5, LG G5 and G6 owners. Seems to be a hardware implementation issue. Maybe same FP scanner manufacturer ?
I have a problem with the fingerprint sensor.. Since I switched to miui 11 with android 10 the sensor worked at times. It works for a day or two, then the menu disappears from the settings and i can no longer use it.
I try tu update vendor partition, wipe data, format data, reinstall new rom with all wipes, reinstall stock rom with Mi FlashTool, any solution works..When i wipe all, it works for a while and than, suddenly, doesn't work anymore!!
I have Mix 2S, i'm sure that is not an hardware problem..
Replace fingerprint sensor
I don't know why you say that you're sure that it's not a hardware problem, but to me, it sounds like the sensor is broken. I suffered this issue in my own Mi Mix 2s and it was caused because the "cable" of the sensor was folded (it's not really a cable, it's more like a flat plastic connector) and it worked one day and not the next. I finally decided to fix it by myself, looking for a youtube video about disassembling the phone and with these tools and the replacement sensor it was pretty easy (and quite cheap, frankly). I hope it helps!

I had the same problem. Mi mix 2s had a problematic/bad assembly line.
I have exactly the same issue. After Android 10 update the fingerprint sensor works for a while. After one day I recognized that the fingerprint sensor is not working anymore. And there are no options or settings in the system settings anymore. So I assume a software problem.

This problem is very boring!!! Have you try a solution, or a temporary fix???
No, I have no idea how to fix. Seems we have to wait till the next update from Xiaomi, which hopefully will fix the problem. It is really boring.

Your assumption is wrong... these options will not show up if the system can't find the fingerprint sensor... Had the same problem and it turned out to be a hardware fault, exactly like mentioned by Kaliotto. You can do a simple test via CIT (tap multiple times on kernel-version). You will find a fingerprint sensor check in there. If it does not find the sensor, it is broken, simple as that. Replacing the sensor is really no voodoo, did it in a timeframe of 30 minutes myself and it was really the first time I ever opened a smartphone. And the parts are really cheap.

I read on differents sites a lot of people who had problems with fingerprint sensor after upgrading to miui 11 with android 10..i don't think that all of us had hardware problem at the same time of the upgrading, it's very strange...
so, to avoid any doubt, i'm searching a new fingerprint sensor..the site suggested in the second posts seems to have problems with payment, any times i try to buy with paypal o credit card, the payment was refused..so i'm searching another reliable site..
I solved the problem. In my case it was defenitely a software bug. I tried to run the fingerprint test at CIT and the phone reminded me that the phone is protected by a PIN and can not enroll fingerprint information. So I switched of the PIN protection and the fingerprint test runs positive. Since that time, the fingerprint options in the setting was back again and I was able to setup the fingerprint sensor as usually.
So I thing the deactivation of PIN protection was the solution to get the fingerprint sensor working again.

So, you only disabled pin in the lockscreen (and set swipe method to unlock the phone)??
I tried now disabling pin and restarted the phone, but no options in the settings menu
Can you give me more details? Thanks
Update! After one day of use, I have to say, that the fingerprint sensor still does not work proper. After a while the fingerprint sensor stops working again. I played around with the settings, disabled the PIN protection and start the phone several times and than the fingerprint sensor was working again for a while. There is still something wrong. Also the CIT test sometimes pass and sometimes fail. Maybe it is hardware failure after all.
What I did: I disabled the password (PIN) protection, means no protection at all. After that I was able to run the fingerprint sensor test at CIT ( as cdfs wrote). This test was pass and the settings to configure the fingerprint sensor appears again in the system settings and the sensor worked for a while.
Since this procedure the function of the sensor is not consistent and I can not definitely say what to do to get it works. In the meantime I think that all the described workaround just works by accident.
NEWS: i changed stock kernel with two modded kernel (Twisted v22 && LawRun9.0_60hz) and fingerprint start to works again!!!
So, my idea was real: it's a software problem!!!!
Try it yourself and give me your feedback
Hi,
I had also the issue that the fingerprint sensor was not recognized. I replaced it.
Then the option was there again but it doesn't read any fingerprints.
The CIT test fails by the last step "Pixel open test"
Then I got a second new fingerprint sensor and replaced it again.
The test fails again in the last step!
These are the CIT messages:
Autotest: Testing
SPI test: Success
Reset pin test: Success
Interrupt pin test: Sucess
Pixel open test: FAIL
So I would say it is a Software Issue
Hello,
so I at the end found some users, having exactly that problem!
I bought a new sensor and changed it. Pixel Opem Test failed.
I bought another sensor with the same result: Pixel Open Test failed.
Is there a usefull solution?

Hi all,
Just got this Mi Note 10 today and while setting up the phone I started to get those weird screen touches..
Happened so often that I enabled 'Show Taps' via developer options and recorded it here:

Okay, this is weird. Which version is it? And did you have already tried to reset your device? If it's still there it's probably a hardware defect.

Right, so no fix really... disappointing as the cameras are impressive
My device came shipped with Android Pie Based Miui 11, no screen weirdness. Just after the Android 10 updates that ghost touches appear. So I guess it's just software bug.
me too, sure software problem.
Thanks for the feedback, if software-related were you able to roll back to fix this?
Happy to try a workaround as I'm very reluctant to send it back..
worth a try though, but unfortunately Xiaomi didn't provide stock ROM specifically for my region so I left with no choice
Completely puzzled as I did a Factory Reset via Recovery and haven't seen the issue for past 2 days, I've left the screen touch tracing on and no 'ghost touch' was recorded..
so I don't know what to believe anymore, got an open return ticket but would hate to send it back without needing to..
how can I make sure issue is gone?
Hi, i had this problem 3 weeks ago, temporary solved with hard reset, worked perfectly until yesterday night when this problem went back.
Hard reset again, problem still there.
Someone solved it permanently?
It is really weird because, if i turn off/on the display, sometime works sometime not :S
The phone came with Android 9 and I started to face this after updating to Android 10. The issue is not extreme as shown in the video, it just the touch becomes slow to respond and hard to type fast with the keyboard. Turning off the screen and turning back on solves it temporarily sometimes.
I tried disabling on screen fingerprint and the problem seems to be reduced now. Definitely a software bug
I'm using Mi note 10 lite it also has same problem. Sometime touch freezing and after press power button automatically fix. Some time need to restart. And also one person told me he is fixed by this issue by turned off fingerprint sensor.

I have the exact same problem as you, slow to respond and hard to type. Need to apply more force on the screen for it to respond. This happened randomly throughout the day but are more common during night time for me.
I think it has something to do with the screen lock pin or fingerprint, by changing the screen lock from ie pin to pattern or turning off fingerprint print seems to temporary fix the issue. Another solution is to reboot the phone. I'm using Note 10 Lite btw.

I am using the Pro version. Looks like this issue is common for all the phone models in the Note 10 series. Yes, I have noticed that this issue often happens at night.
Try switching off MIUI optimization under Developer Options and restart your device. Then switch it On and restart again. This workaround solved my issue.

This fixed the issue for a few days and it started to reappear again. When the issue appears, if I turn on Game Turbo for any app (eg: WhatsApp) that particular app doesn't have this touch issue. Looks like a software optimization or battery optimization of MIUI is causing this issue

What firmware version are u in?
I'm currently at 11.0.16.0 and fortunately this issue did not yet reappeared after the workaround.
This is definitely a software ISSUE with MIUI.

Will try out the MIUI optimization to see whether issue still arise. I'll see if my game turbo have the same issue as you too.

Edit: Mi optimisation doesn't work for me but the Game Turbo trick do work.
Hi all.
Last week my Moto g8 plus started to show message finger mooved too fast on locked screen randomly.
Then fingerprint sensor stopped working.
I have removed all fingers from it - no comments.
Now when I try to enable fingerprint sensor - it is not working. When cancelling the setup - phone goes into boot loop.
Did anyone have similar failure? Is it to be repaired by factory reset?
As far as I've searched similar problem appeared on Moto one vision but I haven't found any software solution.

I never had problem with fingerprint but you can try by factory reset ??* if it continues then install a new firmware
Did rescue with Moto rescue and smart assistant. Still the same story. Looks like it is hardware problem. I think I'm gonna request warranty service
