Hi,
Since i've updated my Oppo Find X5 Pro on Android 13, i have this issue:
I can unlock my phone with fingerprint only one day or two. After that, the fingerprint icon disappear from the unlick screen and I have to reboot my phone to make it work again.
It's a strange issue because i still can open apps with fingerprint...
Do you have any idea to help me?

yeah i got this 1 time, i remember after i change some Lock screen setting (change clock type) then that happened,
the fp icon come bigger and wrong position of lightling sensor.
after reboot it work fine now, even though i change any lock screen setting.
I determined it was lock screen bug.
Hi,

Hello.
I replace screen on my P30 pro on official Ukraine Huawei Service, but after this fingerprint in screen didint work.
If I try add new fingerprint phone say error "Registration error".
Official service cant solve this problem.
Please let me know why need for solve problem? Thank you
Sounds to me like Huawei have done exactly the same as apple have done and used and encryption method to lock the specific reader to the board. I havnt had a p30 Pro or p30 apart yet but I belive other phones with in screen finger prints can be swapped

I have so similar problem. Just disable authentification at all (even PIN, FaceId, others). Then turn on PIN and add new fingerprints. Worked for me.

Need calibration. Used to work for a huawei repair centre but never see this problem.
In huawe centre they have an app to calibrate the fingerprint
My mi 9 seems to be able to only detect 1 finger. Completely wiped phone and problem still persist. Anyone with same issue or able to fix issue?
I have the same problem. Have you found any solution?

I have that same problem. Could you help
Happened the same issue to my Mi9. Multi touch was working normally but suddenly it stopped working while I was zooming on a web page. Then I made a factory reset but still didn't work. Today I updated to Miui 12 hopping the problem would be solved but still no success. I think this bug is related to Android 10 as I saw elsewhere someone rolled back to Miui 10/Android 9 and things got to normal. On the other hand this is not a hardware failure for sure since multi touch keeps working normally on apps running in game turbo mode.
So, has anyone found how to kill this annoying bug?
Thanks for any help.
ive been searching everywhere how to fix this. i already email xiaomi about this issue. still didnt find clue how to fix this bug. still hoping that xiaomi will fix this issue.
This issue is a shame for Xiaomi!
As far as I know the only solution is to downgrade to Miui10 and stuck on this version or take the risk to upgrade to Miui11 (not recommended for obvious reasons) or the fresh new Miui12. So far I've been using the "turbo game" thing to workaround the bug. I had to install some alternative apps from Google Play (such as Chrome Beta, other gallery app, Google Maps Go...) to use instead of the stock apps so I can use them with "turbo" and get pinch to zoom working. This is not the best way to solve the issue -- the ideal is to get multi touch back working again without the need to resort to any tricks -- however it works very well. Maybe one of these days I'll get some patience to setup the good old Miui10 again...
i also have this ghost touch on the upper part of the screen. it came same time as the multi touch issue. it cant even fix by game turbo. i cant even play games normally like moba or fps game. i dont know if its just me have this ghost touch issue. its a big shame for xiaomi flagship phone?
No news about this issue? Everything works fine with Pixel Experience in my MI9 but multitouch. I remmember I solved another problem (auto-rotate didn't work for the display) and I solved it flashing only last version of "persist.img".
Same here bro!
I bought my Mi 9 in February and everything worked well. I also upgraded to MIUI 12 with no problems at all, then suddenly multitouch stopped working.
If I flash Pixel Experience will the problem be solved?

No way, Installing PE doesn't solve the problem.
I'm going to try it with new kernels and FWs.

Try to flash MIUI 10... I read somewhere it should work, because MIUI 10 is built on Android 9, which doesn't have this issue
same i have this issue, i tried miflash. the only workaround are miui 10 and game turbo method.
also i have this nonresponsive part of the upper screen, right where most game analog button placed. idk if this "dead touch" is connected to this multitouch issue
This was the first and probably the last Xiomi I bought. Back to iOS. Bought a second hand iPhone 11 in mint condition. Working rock solid! Crap Mi9!!!

Annoying ghost touch on upper screen
Have to type multiple times because It keeps ghost touching...
Can't sell the phone, because of these issues...
Miss my Galaxy note
Is there a fix to this issue now? GameTurbo enhances the touch so that multitouch works. There must be a fix to this.
I replaced the Mi 9T Pro amoled display with a new original one, but the fingerprint doesn't work. The fingerprint sensor is still working, the problem is related to the calibration. I tried using the "Activity launcher" app to calibrate the sensor, I chose "In display fingerprint" then "SPMT", but this process failed when it asked to "Calibrate, put the FLESH CHART then click next" with error "0x14 the number of bad pixel is abnormal".
I know that "FLESH FLAT" means that I need to use a mirror on the fingerprint, but what does "FLESH CHART" mean?
Thank you

Hello , There are issues with the miui 12 update. Is your screen really 100% original?

There is an official procedure to perform the fingerprint calibration?
Thank you
according to your photos it is not the original screen but an adaptable one. the reference is not the same look carefully ...
sorry I don't know the procedure ...

Thank you for your reply. I bought this spare parts on eBay. It was described as original AMOLED
About the reference, do you mean the code that is in the bottom of the screen on the gray tape?
At this point I will try to change it again... There is a shop where I can buy original spare parts? I know that this one is a good shop https://dragon-tt.com/Products.aspx?gid=95 but you need to wait some days for the shipment because they ship from China.
Thank you
I think that of your link is good however I do not know the difference between the beginning of the serial number JA and JC or JB ... Anyone know the difference or is it just a year or a place of production?

Dragon-tt give me this reply:
This item is 100% original new.
It recognize the fingerprint .
You can not start calibration process ,because you have no tool.
Only xiaomi have the tool to calibrate the finger print.
Our screen comes with JA.
I think it is not a problem.

it still seems weird to me. but if so then Xiaomi should be able to fix the problem with an update.
Have you tried to factory reseting the device?

I see that there are some topics with reports of the same problem, that is: difficulties with the fingerprint scanner after replacing the broken screen of an MI 9T / K20D [PRO].
A summary of the situation:
Until MIUI 11, the MI 9T / K20D [PRO] worked normally even when their screen was replaced by non-original screens with only 5 multitouch points, sometimes described as "tft" or "oled", including the fingerprint scanner.
Most of the screens available on internet sellers are of these types, and vendors often insist that they are original. The easiest way is to check the number of multitouch points, if it is not 10, it is not original.
After upgrading to MIUI 12, the fingerprint scanner of the MI 9T / K20D [PRO] equipped with these screens no longer works, restarting the device whenever trying to register a fingerprint. This is not a calibration problem.
The only solution found so far is to replace the non-original screen with an "AMOLED" screen, with 10 multitouch points, which is either original or at least has characteristics similar enough to the original to work.
This topic has a good explanation on that subject https://forum.xda-developers.com/k20-pro/help/miui-12-fingerprint-unlock-defective-t4122135
I hope it helps
As Thoriq said, have you tried factory resetting it? i had the same problem when i replaced the screen on my cepheus with a bad quality one and that fixed it

Hi guys, after reading the last update in this thread, I tryed to install a clean Global ROM on my Mi 9T Pro, and it works, but due to the cheap quality of the new AMOLED, the recognition works 1 time on 8.
I followed this guide step by step, and if you open this link from a smartphone, turn on the "Desktop Mode" otherwise you will see a blank page: https://c.mi.com/oc/miuidownload/detail?guide=2 - to follow the guide you need a Windows PC -.
If you need to unlock the device, first you will need to turn on the "Developer options", go into the "Mi Unlock status" menu, and bind the Xiaomi Account with the unlocker. Of course, you will need the Xiaomi Account password.
Ater the unlock, according to the guide that I linked before, the device will reboot, but sometimes it stops on the coloured "MIUI" logo. So after 5 minutes without any change, I turned off the device pressing the power button, and then it rebooted correctly. After the first reboot, it asked me to add again the Xiaomi Account password, because the device was already paired with an account. At this point it booted, and I turned off the device before selecting the system language, and I continued to follow the linked guide from the STEP 3.
The nice thing is that the fingerprint works again, unfortunately the bad quality of the display cannot be fixed without replacing it again.
Thank you for your help guys.

DEAR SIR I HAVE THE SAME PROBLEM AND FOLLOWED your procedure but no result.
I bought an AMOLED screen manufactured by Samsung, complete with frame, supports 10 touch points, with color quality and contrast very similar to the original screen of my Mi 9T. At first it is a good display, the seller has guaranteed that it is of Original / OEM quality. Here is the link to the part I bought: https://www.aliexpress.com/item/4000156095854.html
The only problem is that biometric recognition does not work on MIUI 12! The sensor registers my fingerprint but the phone does not unlock with it. I've tried to downgrade to MIUI 11 and it didn't work either. Any solution?
same situation but the one I got is branded OLED instead of an AMOLED one. I wish there's a way to calibrate the fingerprint as I registered the same finger thrice for accuracy but it still doesn't detect properly.

You can try to follow what I have done here. But, if you didn't bought the original spare part, you will probably be unable to use the fingerprint scanner due to the bad quality of the display.
It worked either you replaced original (10 or 5 finger touch support) Theres a tricky way to make it done.

Good day.
I recently replaced AMOLED screen. Fingerprint works, auto brightness, too. But when it comes to always on display, there's a problem. It doesn't work. When I unlock it with button it sometimes shows for 0.5 seconds before going to the homescreen.
Does any one have any ideas how to fix this?
Thank you.
EDIT: Flashed xiaomi.eu MIUI 11 version (before it was xiaomi.eu MIUI 12), and now AOD is working, but either full brightness or minimal (barely visible) brightness, doesn't step up as it should in relation to the ambient brightness. The auto brightness when unlocked works as it should.
Hi, i have the same situation...did you found a solution?
Thank you
Hi I have exactly the same problem. did u solve it? i´ve tried flashing miui 10, 11, 12 Via twrp or xiaomi Miflash, Global or Xiaomi.eu... none of that worked. My AOD is too dimm. Also my fingerprint works very bad and have brightnes issues when touching if i set it to show on AOD... i saw there is a calibration tool for the fingerprint recognition but how to solve the AOD problem? Please help. My replacement is also an Amoled screen.
Where did you buy the screen? I'm trying to find an original replacement online store (who ships to Spain if possible).

The first screen was from Aliexpress it claims to be original but clearly not. After both problems with fingerprint and AOD i've changed it for a new one buyed from a repair store localy at Granada, Spain.
All i can say its that the box says esmovil.es website that its for profesional repairs stores only i think...
This new one comes with the phone frame and its claimed to be a xiaomi service pack. All works fine now. Under direct sunlight you can see the diferencies in the fingerprint and light sensor holes with the fake one. You also need to calibrate the figerprint sensor from the CIT menu.
I suggest to buy an OEM replacement to finish all kind of problems related to AOD and fingerprint
Does anyone know what is the compatibility trick behind Huawei P30 Pro fingerprint sensor?
I have got issues with mine.After screen replacement it worked fine,until the microphone stopped working at the bottom board.So i went for a new one.And there the fingerprint issue started.I cant enroll a fingerprint.
I went for another board,new sensors,new main flex.It simply does not work,recognizes it,but does not work.Calibration tools and softwares did neither work.Tried to update/reset,also unsuccessfull. Actually it worked perfectly once,read the fingerprint perfectly,but after restart did not work again.
So,i am stuck... I know in the past i have replaced screens and sensors on P30 and P30 Pro without similar issues.
Is there an trick or must i bring it to Huawei centre to pair the hardware?
Hi,
Did you find a solution for this issue yet? I'm about to replace the fingerprint sensor, but cannot find how I can calibrate the fingerprint sensor afterwards. There seems to be some software app by Huawei which can start the calibration proces but it's nowhere to be found.
Anyone?

Great for you, i will try that for sure in the near future, but can you please explain what do you mean by original rom? The one that was first on the phone when was sold? Or you used emui 12?

Well, i was waiting to get answer from joaofbc but no answer, i didn't try anything on my own, i use phone daily and didn't want to mess it, but face recognition is working fine so i don't care about fingerprint that much.
