Is it just my device or others are having a problem with the fingerprint sensor of honor 9 lite as it does not accepts fingerprint.
Whenever i try to enroll the fingerprint it always displays a message to keep the finger in the centre to improve accuracy.
Please provide a solution for this.
I've tried resetting the device that didn't helped.
My mom was trying to register her fingerprint on my Mi9 but it was a very difficult task since the scanner couldn't detect her fingerprint. After a long time and being able to register the fingerprint, now it's near impossible for the phone to scan her fingerprint and unlock the phone. Meanwhile, my fingerprint unlocks easily almost every time, so I really don't know what's happening and how can I fix this. I'm using MIUI 10.2.26.0 EEA. I wanted to put the global beta to try, but since they won't update anymore global betas I stayed with the global EEA.
She's looking for a similar phone, but if on-screen fingerprint scanners have a problem with her fingerprint, she will have to stay with standard fingerprint scanners that she never had a problem with.
I'm currently using a screen protector, but since it works great with my fingers, I don't think that's the problem.
Are there any tips on fixing this problem or at least make it better, like finger positions or doing something with the finger before scanning, without having to change ROMs?
If it works ok with your fingers, "probably" not a sensor or rom problem.
I always register same finger twice for better reading, but if your mom's fingerprint is washed out, will never be 100% efective.
Hello,
I bought the MI 9T Pro, and during my tests I've observed a weird issue.
When dragging the finger vertically on the screen , exactly in the middle it stops working. Mostly is observed when trying a paint type of app, is not recognizing the fingers when arriving in the middle of the screen. sometimes it works.
I tried doing a reset to factory settings but it didn't helped.
The phone has MIUI 11, i can't rollback to a previous version like MIUI 10, as i think this is a software issue and not a hardware one.
Any advices?
Kind regards.
Screen record in the miui testing app & post
(*#*#6484#*#*) -> Test touch sensor
Or can even test in apps like display tester or Antutu benchmark
Hello, i tried also this method. The test is assed but when nearing the centre of the screen i can see how a diagonal line goes for aproximately 1 centimenter straight vertically an after it passes the center goes back to drawing diagonally. A made request also to Xiaomi global support. Gave this advice and also update to the latest patch. Still didn't worked.
In the end i returned the phone and buyed a new one.
Kind regards
Hello everyone,
A few days ago I installed the V11.0.4.0.PFGMIXM firmware and no longer face the Proximity problem anymore.
Just download and flash newest Firmware You can download it at here: https://xiaomifirmwareupdater.com/firmware/lavender/
perfect, thanks for sharing, excuse me, after doing this do you know if it also solves the GPS location problems?

I don't meet any problem with GPS location before and after flash this firmware.
I just started experiencing a proximity sensor issue on MIUI 11, EU version 11.0.4.0
It occurred a few times after longer phone calls (more than 10 mins) when I removed the phone from my face, the screen would not light up. Neither the lock button nor the fingerprint sensor would wake it up, and I had to wait for the other person to hang up. Or maybe it only reacted to the lock button after 5 seconds or so.
I don't remember this happening previously. Is this something you guys have experienced?
Same problem

I faced same problem and i never paid attention to it. Now and I'm reading your post, i come to realize that the redmi-note-7 has a sensor problem and i have a miui 11.0.4.0 global version
I have heard about other people having proximity sensor issues on earlier versions of MIUI, also different editions (China, Global, EU). I've even advised some of them to re-calibrate the sensor through the service menu. I've been using the phone for 9 months now, I believe. I've updated it regularly and never reset it to factory settings. If this keeps up, I'll try re-calibration. If it doesn't disappear with the calibration or the next MIUI update, only then I'll consider factory reset
Hello
How I have Redmi Note 9 Pro MIUI 11.0.4.0, how can I turn off the proximity sensor? I have the screen problem other people are mentioning above
When I try to unlock my device the screen lights up after 3 to 5 seconds and it is happening frequently right now. It started to happen after I flashed MMX V12.5.3.0 and it happened even in custom ROMs too and right now I'm in Indian MIUI stable and I still face this problem
Also for me: i'm on redmi note 10 pro EU V12.5.1 rom. On 12.0 miui no problem on 12.5.1 sometime wake device delay 5 secs, but sometime.
I get the same happening sometimes, I also had it on my Poco X3 so I guess it's MIUI and not specific to the Note 10 Pro.
