Basically I've recently bought poco f1 for pubg. Updated it to latest miui indian version available i.e. 10.3.8 installed pubg but when I enter in the real match,the screen becomes unresponsive for like milliseconds when there's an enemy around. In training mode it works just fine.I have to hard swipe to make my screen turn around.This problem doesn't exist on my redmi note 7 pro so I'm assuming it's not a bug from the game.
Also I've tried multi touch tester app and I do notice ghost touches.According to many threads disabling 3 fingers swipe gesture will majorly fix this but the problem still exists for me. Although I did not encounter any ghost touch issue in real usage but it still exists.
Here are the things I've tried till now
Tried custom roms like pe and lineage os problem still exists.
Tried many custom kernel like frenkel and sensational (sorry if I misspelled).
All were compaitable kernel and roms.
Tried miui with custom kernels.
Disabled 3 finger swipe gesture.
My screen panel is Nvt-ts (Heard this works fine but mine doesn't)
Most of the developers are not talking about this now but I've searched hours for solution bht didn't find any.
I'm just a newbie at these things so sorry for any mistakes also pardon for my English.
Hoping for some permanent solution.
So after trying a lot of roms and custom kernel. This is the only solution I've found yet.
Go to play store and download a app names touchscreen repair.
This app helps to increase or decrease the touch sensitivity.
In my case it seemed as if the touch my a bit over sensitive.
So I intentionally hold the touch a bit longer and made the app to decrease my touch sensitivity by 9ms.
This made my crosshair jump alot less than it used to be.
95% of my problem is solved now. This is the best I could find.
P.S. I'm not a developer so I don't really understand how this app works. I used terms like sensitivity so I could explain my issue
Hope this helps...
