[EDITED]Touch Inaccuracy And Lag While Using Keyboard, PUBG, Modern Combat And Others - Xiaomi Poco F1 Questions & Answers

NOTE: This Post Was Edited To Contain Latest Information
The Problem:
While playing any game that uses multitouch i.e. there are two regions on the screen:
i. Joystick area - with which the character moves.
ii. Aiming area - with which you change camera angle and aim at the enemies.
When you try to aim while moving, the crosshair is inaccurate and doesn't stops where it should but a little left or right off where you wanted it to stop. Due to this issue, the game feels like having frame drops.
If you will type too fast there will be a lot of mistakes in typing try typing some words on the keyboard on the extreme of screen, like "que", it shows 'uqe' or something else, the keyboard can't recognize fastly typing words.
Problem in zooming in and out, the touch behaves wierdly.
Many people have made videos regarding this, please see the following videos:
PUBG Bad Aiming
Zooming in problem while playing Clash of Clans
Multitouch Issue On Poco F1 Running On MIUI10 Mi8 ROM
Multitouch Issue On Poco F1 Running On Android 9 Pixel Experience ROM
What Have I Done Till Now:
I have replaced the product and the problems are still there, that means that the problem exists in almost all the devices. I have tweeted them, mailed them and tried everything but Xiaomi or Poco is not even bulding, they have stopped responding to any complaint regarding the device. Do you know what to do when a company doesn't even reply to your queries? you boycott them!
UPDATE: Sold the device and bought Nokia 7 Plus.
Report this issue if you have it too:
If you have the same issue, please report this.
This issue exists in all the firmwares : 9.6.11 -9.6.18
I have posted this everywhere and seems like a lot of people have this issue, Xiaomi is not responding. This is a fraud if they say/do nothing for this.
This is not the 3 Finger Screenshot Issue:
Sorry to burst your bubble but this is not the Ghost touch problem, if you have ghost touch problem, it can be solved by disabling this screenshot feature, but the problem for which the thread is made is totally different.
How to solve the "ghost touch" issue for now: https://forum.xda-developers.com/poco-f1/how-to/fix-multi-touch-ghost-touch-issue-t3837453
Why am I writing about this everywhere?:
Redmi note 5 and Redmi Note 5 Pro which were launched a lot of months ago still have this issue and Xiaomi is not responding to them when the problem will be fixed and they are just ignoring the users. If you think I am lying, just search for "Redmi Note 5 Multitouch issue" and you will get your answer.
Xiaomi has done this with us before:
Last time they did something like this was the launch of Mi4i, ask any Mi4i user, how they launched the device as a Flagship and later they pulled all the support for the device and made it so bad on the software front that it was rendered useless after just 1 year of use.
If this problem exists in all the units then they probably used cheap hardware on all the units except the armored edition that was sent for review or they probably ordered touchscreen digitizer from multiple companies some from good companies and some from 3rd class companies and randomly used it because these kinds of issues in a day old phone is not possible.
Update (November 28 2018):
Few users are saying that the touch is slightly improved in latest 8.11.23 beta. Slight improvement 'technically' means that the changes are being done on software and the hardware still suffers from the problem, result of this:
1. Problem will never be fixed completely, there will be slight or may be a noticeable remnant of the issue in some form.
2. Xiaomi will someday break the code and everyone will suffer with the problem again.
3. Fix will not be available for custom ROMS, unless someone manages to port it, Xiaomi is lazy enough to not provide the fixes.
But the people on the Xiaomi forums are complaining that the touch has become terrible after the update: http://en.miui.com/thread-4687147-1-1.html
Don't know who is speaking the truth.

Sometimes the touch is not registering, yes. I used the multi touch tester all and I used four fingers to press and pull. On one out of four occasions it doesn't recognize.

---

My touch screen has the same problem too.. Registering more touches than there are and missing touches too at times

---

Working fine on mine. Disable gestures before testing.

Let's say it is due to the gesture, should the display be able to recognize difference between 3 touches and more than 3 touches? and even if it's due to the gesture, why does it have ghost touch?
Well, after disabling it:
The PUBG issue still is there.
4 touch issue is less frequent on disabling gesture but doesn't totally resolves.
Now,
It sometimes makes strange loud noise, happened in front of the engineer who visited me.

Then it’s probably a faulty unit.

I hav the exact same problem with mi 6x, that ghost touch input after taking three finger ss but this is gone by turn off but the hell problem is that ABOUT THE TOUCH LATENCY PROBLEM IT IS BIG HORRIBLE WHEN SCROLLING EVEN SCROLLING IN SETTINGS AND I HAV COMPARED TO REDMI NOTE 5 AND IT HAS FASTER TOUCH THAN MI 6X AND MI 6X TOUCH IS REALLY ****IN ANNOYING AND I HAV ALSO GOT KEYBOARD FAST TYPING ERRORS... THIS IS IRRITATING ME TOO MUCH , BTW I GOT THE SAME LATENCY PROBPLEM IN REDMI 5 PLUS BEFORE BUT NOW IT GOT FIXED BY UPDATING SOFTWARE UPDATES, SO I CANT SURE THAT ITS SOFTWARE OR HARDWARE OR CALIBRATION PROBLEM , REDMI NOTE 5 HAS THE EXACT SAME HARDWARE WITH REDMI 5 PLUS AND IT GOT FIXED BY SOFTWARE UPDATES SO HOPEFULLY WE CAN EXPECT MIUI UPDATES WITH TOUCHPANEL FIRMWARE UPDATES , ****ing work Xiaomi

Btw i also wanna know what display ID and touch sensor IDs?? I hav mi 6x same shhit problem and the display is tianma and touch is nt36672 from novatek

Same problem here while typing. I've tried different keyboards, Gboard and SwiftKey. Same typing issue occurs with gestures or buttons enabled.
Global version 64gb, MIUI 9.6.14.0

---

I've tried a GSI build and unfortunately I've just tried the keyboard bug and it still occurs... I hope it's not a hardware issue. Otherwise clearly I'll send it back.
