Hi, today in the morning i noticed an issue with the touchscreen, especially, on the left edge. I noticed that issue while i was writing and trying to switch the key of numbers and letters.

While i try to write and press "?123 or ABC" key, sometimes it doesn't work and i have to press twice.
Have u ever noticed something similar? I have tried by changing the keyboard, restarting, calibrating and I can't fix the issue.

Thanks in advance.

I have the same problem. In my case, the other side of the touchscreen has the same issue as well (Gboard enter button). Did you guys check the touch sensor test (the one in diagnostics menu -> additional tools)? It seems that only two squares are affected. The left and right outermost square in the penultimate row. Try tapping fast, it's sometimes not registering. I really hope this is not a hardware issue though...

Have you tried to disable screenshot gesture? Please try it and report if the issue are resolved. I don't have a rdm8pro but on other redmi i have the same issue and the screenshot gesture of miui create the problem.

Unfortunately it didn't help. The issue is still present.

it's exactly the same in my case , I have noticed that more happens if you touch repeatedly in the middle of the screen and then at the ends
sorry for bad english

I went to a local Mi Store earlier today and the unit they have on display suffered from the same touch screen issue. I don't think replacing the device would help as it seems that a large amount of them might be having the same problem. If anyone's device is functioning correctly, please let us know.

This is just in the corners , I noticed to.. when I want to press 123 to go to numeric pad, I noticed that the screen dont react in some times..that not the screen issue, this is more like ..I dont know how to explain it on English..but everything is ok with screen when you press the right place..

Try press this line that I marked on this screenshot and you will se that the display is not responding.. this is not hardware or software error.. this is jus the line on keyboard that have no function and not react when you touch it. But when you touch right place on number 123.. everything is ok..
So ..your phone and everyone else is working fine.
Also this is just happened on keyboard..on other apps,this place on screen also like in CIT test working..

Try touching the highlighted tiles and then compare it to other ones. Look at the attached screenshots.

the touches have to be fast, if you make them slow the problem "disappears"

I can take a screenshot,how did you do this?
You mean you are unable to access this particular test? Just tap the 3 dots in the top right corner of the screen when you get to the CIT test menu. Then select 'Additional tools'. Tap the 8th item on that list which says 'Touch sensor' and you will be greeted with that test screen.
