Hi! this is my first time to post about my Mi9T Pro (Global version) "6/128" that i bought yesterday here in Philippines..
my issue is only Noticeable in Playing Games like Competetive like "PUBG, Call of Duty, ROS, any Games! i think all of them ?? what i mean is.. a HUGE TOUCH DELAY!! when your 2 thumbs are on the Screen and your right Thumb swipe faster to rotate 360 is not that accurate.. i can really Feel it as a GAMER. i bought this Device more on GAMING, because of Notchless Design and AMOLED panel.
when i Play any Games i mean the Dragging on Screen Sensitivity when Scoping or Not. its not accurately going on point where i swipe my thumb.. for Example: i swipe upwards.. it goes upwards also but theres a shaking on Screen.. i cant AIM properly..
soo is there any solution on this?? can a Custom ROM or Kernel can fix this?? cause i will Unlock my Bootloader immidietly! i dont have Tempered Glass installed. only the stock Casing that are intack on the Phone.. nothing else..
soo i need your advice! im currently on 10.3.3.0 (PFKMIXM) version. latest Stable
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 K20 pro model still continues to touch problem ?
Is anyone able to solve this touch problem with Custom rom or a different way ?
İ am currently using mi8 processor and 3.5 mm jack input for the k20pro model would like to switch. I'm a PUBG Mobile ace tier 4 finger and gyro player.
Do you encounter any problems in the K20 pro like drop fps vs touch issues ?
I do have the same issue through the phone even while typing and playing coc, Netflix, homescreen etc
i m facing weird issue in touch on the top portion there is no respond of touch but some time its detect many touch like ghost touch .redmi k 20 pro ,one more thing
the ghost touch issue can be correct by glass change of k20 pro or full folder because glass change cost less as compare to folder change

I have exactly the same problem. Top of the screen randomly stopped responding. Pretty much the same amount of space as in your case. Also sometimes it does ghost touches, but its rare. Usually this part of the screen just doesnt respond. My phone is 1 year and 4 months old. Never dropped it or anything like that. Tried restarting - didnt help.
Is this a hardware problem or software? Did you fix it for yourself?

Simply disable three finger screenshot gesture in phone settings. This will get rid of ghost touch issues on any OS
MIUI 12 Fingerprint Unlock defective
After upgrading to MIUI 12 Global OTA yesterday, fingerprint unlock stopped working. When I select fingerprint unlock in settings to switch it on and enter my PIN, phone goes dark and restarts (MIUI splash screen). Any suggestions? Phone is stock...

Hello everybody,
quick question for you. I started modding OPO and now after years I am using project elixir on my k20pro, in terms of backup from the ofox recovery, would you recommend to periodically backup also:
- modem: fw config file
- efs: HW config file like wifi, bt, imei. In case of issues having a backup of IMEI is fundamental I would say
- partition: sensors and modules config file. in case of issues it could be necessary having them!?
what is your opinion?
thanks

I live in Toronto and considered myself lucky to find someone to change my cracked screen. All seems great, accept now my fingerprint sensor isn't rally working. Every other aspect seems to be perfect. Anyone had this issue? Anyone changed screens? Anyway to reset the fingerprint sensor other then erase and try again?
Any help would be appreciated.
TIA.
Maybe he forgot to reattach it and your phone basically has no fingerprint scanner now? Idk open it up and look for yourself.
Thanks.
Was it an AMOLED screen, AliExpress sellers are now selling TFT LCD replacement screens, alongside AMOLED screens, at about half the price. LCD screens aren't good with FOD ordinarily.
I replaced mine back in December with an AMOLED, but I've been on custom ROMs where the FOD isn't as good as stock anyway, so couldn't say if I'm getting as good performance as before. It recognises my left thumb 9/10 and my right thumb 5/10, and never as fast as stock, which seems about par for the course with custom ROMs. I considered flashing MIUI just to test the FOD properly after fitting the replacement screen, but never got round to it.

Thanks for getting back to me, yes it is an AMOLED and I do have an update!! It works perfectly once the screen is on. If I remember correctly I was able to use the scanner from the lock screen with the animation of the fingerprint.
Now I can only use it if it's in the on position showing the time etc. so I just used lift to wake so it works 100% now.
Thanks for the attention.
I have the same problem, caused by replacing it with a screen from a random ebay seller (local warehouse).
After looking through a few Aliexpress listings I noticed that some product descriptions contain a note that they sell only a compatible part, not an original. Others state "100% original" or something along these lines. And many just don't write anything... I assume most of them are fake, if not all.
It is definitely a OLED, but the fingerprint gets almost never recognized, it is hard to complete even the fingerprint setup. Only works if I increase the brightness manually. The screen goes somehow much darker in fingerprint mode, instead of making a bright cyan dot like the stock part. Enabling the screen before unlocking helps on mine too, I think the reason is the higher brightness there, but still not as good as before with the standard screen.
In addition the image is a bit worse, especially looking closer at solid grey, it looks grainy. Normally it should look clean. Do you see that as well?
Scrolling is also not as good, doing a fast fling results in a much slower movement than with the stock screen. It works and might not be as noticeable, but having two devices side by side reveals quite a big difference. I bought another 9T just to try this...

I doubt my screen is original, but it's definitely good quality. There's no noticeable screen quality issues, either with display resolution, colour or motion. Haven't compared it against another Xiaomi/Redmi display, but against other FHD+ 60 Hz AMOLED displays on a mid range Samsung and a top range Honor, it's just as good.
I have the same exact issue after replacing my own screen. It seems to have to do with the finger print animation lighting up when your finger gets in contact with it.
I've disabled the finger print method completely and that seems to help.
I'm not sure how to fix this though, as I would like to use it the way it was intended myself.
(btw factory resetting the phone helps with the success rate of the finger print sensor if you haven't tried that)
Perhaps if you need to buy a new display, I bought the "AMOLED Black" variant available here. Has been replaced on a Mi 9T, everything works fine and it's as good as the original display. It seems like the price has dropped significantly, almost 50%.

do you know what is the difference between "original black" and "amole black"?

Yes, it's all working. I only have no idea what the difference is between "AMOLED" and "Original". I assume that perhaps Xiaomi certifies those displays as original, however, they're most likely the same as the "AMOLED" displays, maybe with slightly better color accuracy. I didn't notice a difference between my Mi 9T Pro and the Mi 9T with the replaced display.

I changed the display but I have problems on my MI 9T Pro with MIUI 12.
5 dot instead if 10 dot touch.
Double Tab To Wakeup didn't working.
Fingerprint sensor didn't working (restarts after using).
All these points are working on your phone with this display from AliExpress?
If yes, I will buy this display too .....perhaps .....

It's not my phone which has the replaced screen, but from what I know, everything is working. Besides that, they're quite cheap now (I had to pay double for what they retail now since it was cracked roughly half a year ago). The total job would cost you under 100 euro to get it replaced.

The screen used on my device was this link (the amoled model) and everything you described is working perfectly:
https://it.aliexpress.com/item/4000691686320.html?spm=a2g0s.9042311.0.0.41084c4d4VnhIQ
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
I'll start my question simple: What display panel does the M3 Pro/Note 10 5G have, and does it have issues with image retention?
My old Redmi 5 Plus (vince) has a Tianma panel, and it has a severe image retention problem. Exact reason why I got myself a new M3 Pro. I heard Note 8 users with Tianma panels also have this issue.
I've tried going into CIT under 'Version Info', and I saw the vendor was TRULY or something. I've been searching on the net for a couple of days, yet nothing shows up, other than the alleged company's website.
