Every couple of days I have a problem with the screen becoming VERY unresponsive. It seems to affect the whole screen and requires touching characters on the keyboard, web buttons, app icons, etc. multiple times before the touch is registered. The problem persists until I reboot the device.
I haven't rooted yet or otherwise modded it at all, but maybe I have a poorly optimized app running? Haven't tried to capture a logcat yet either (and frankly wouldn't know what I was looking at).
Has anyone else experienced something like this?
Thanks!

Looks like mine is suffering something similar to the problems discussed in this thread:

I also have this issue. Was able to reproduce with multi touch tester apps. When I cross axis the touch points freak out. I think it's a grounding issue. If I touch the headphone jack or have headphones in the issue goes away. Called in a RMA request yesterday. Hope this issue isn't present in the next device.

Hi all,
I'm wondering if anybody has experienced this issue.
Yesterday i charged my phone up after the the battery drained. The phone booted up normally until the display dimmed slightly??? The display is now as though its in power save mode lacking the lovely vivid appearance. Greens and reds seem dull??? Any ideas. I am considering trying to reload official firmware. But before i do i would like to see if anybody else has experienced this issue.
Regards
Joe

Recently I have changed the display of my XZ due to some touchscreen problem.after changing it everything was good when using for normal works like calling or browsing.
then I started to play games like Clash of clans or anything,the screen keeps gliching where the colours were more detailed.
then the problem started to be seen while seeing photos or videos.then when browsing anything detailed or colourful.The problem is increasing.
what is causing the problem?is there any problem in the connection of digitizer?because when I tried to take screenshot of glich,it was fine.
what can I do now?
I don't know if XDA is the place to search for such stupid problems,but I NEED HELP BADLY!

Well, i think your screen is faulty. It has either been not of top notch quality like SOny and thus when there are more colours than it can produce, it flickers. It could also be due to an old screen on which water/any other liquid had been spilled. I think, wherever you got it replaced, you should go there and get it replaced again.
Good Luck.

Hi , just wanted to ask if anyone had any problems while gaming ? I've been playing bullet force and notice while moving about the touch screen gets sticky inside the game.
It does not hot happen straight away but more like 3 or 4 mins in to the game.
Seems to me it's something to do with the heat which goes through to the screen and warms the screen up so much that that the touch does not register correctly.
Just wondering if someone can try and see if they have the same problem or it could just mean mine is defective?
The only thing is that I'm not having any problems with other games tho.
No problem here. I have tried it and played like 15 minutes. I believe there is a problem with the game code.
I don't have this problem with my games. Try other games to see if you have same problem.
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!!!

Have the same problem here!!!
Upper screen DEAD
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.
