[Fix] multi touch/ghost touch issue

Those who don't know there are some people having ghost touch issues on POCO f1 and one guy able to capture it on the video. I personally didn't had the issue but after trying I was able to recreate the issue on my device. soon after I found the cause and able to fix the issue. this may or may not work on your device but absolutely worked for me. this seems to be a software bug. and no-one needs to panic. hopefully it will be fixed in next update.
how to recreate the issue?
Steps
1. download a multi touch tester app I used this
2. first do some testing yourself see if you can spot the issue
3. now do 3 finger swipe down (phone will take screenshot)
4. now randomly touch your screen with 1 or 2 fingers you'll notice 1 or 2 ghost touches.
How to fix Fix it?
Steps
1. go to settings>additional settings>button and gesture shortcuts>take a screenshot
2. and set it to none.
3. reboot
that's it!
the issue should be fixed
please let me know whether this worked for you or not

Yes.
As you mentioned issue was there.
But fixed with those steps.

Good stuff. I was skeptical at first since I knew something was off sometimes. Thanks for confirming it. Should be fixed if they took notice of this bug.

Thanks! The issue is 100% reproducible with the app. By turning off 3 finger screenshot shortcut, the issue goes away.

Guys, please file a bug, so this can be fixed and we can go back to using this feature.

1.Yes, that issue is due to the screenshot feature, but shouldn't the phone be able to distinguish between 3 finger touch and more than 3? Either take screenshot on four finger swipe or register it.
2.Can you please confirm if there is accuracy problem in PUBG aiming when you use multitouch? Like the multitouch bugs in Pixel and Zenfone Max Pro but quite subtle, the thing about the other devices are, they look and have been acknowledged by the respective companies regarding the issue but in our case, Xiaomi or Poco is making no announcement or anything.
https://www.youtube.com/watch?v=e5K2N6McC_s

The issue comes up after taking a 3 finger screenshot, but disabling may not be the only solution as this feature is quite useful also
What I have noticed is that after taking screenshot ghost touch is there till we use 1,2 or 3 fingers. Once we use 4, 5 or higher fingers the issue goes away.
Isn't it better to just touch screen with 4 fingers after taking a screenshot which somehow resets the ghost touch issue.
Have tried this solution with multi touch tester app

Mine is just fine even when 3 finger swipe screenshot is switched on

I can confirm that ghost touch issue still persist even when disabling three finger screenshot.
Mostly visible in pubg.

Great, fix worked

I didn't relize the issue but nice posting

Stop it! This is not an issue. It happens on mostly every phone that supports gestures. Test it on OnePlus 6 and you will get the same result.

Exactly! There is no need to prove this issue because Google itself confirms that they have done a mistake by releasing it in Oreo and they have also promised to give a fix in later Pie updates. And people who wants proofs can look up in the internet about the "Multi touch Oreo Bug" problem and how it effects user experience rather than spamming here to make a point.

Dude, google fixed the issue in the May or June patch and all other OEM's had to merge their builds to fix it. The problem is not there in MiA1 or MiA2.
Here is the bug:
http://en.miui.com/thread-3746297-1-1.html
Thanks

Maybe the original solution for 8.1 and P devices will work for this? It will either cause a bootloop, do nothing, or fix it... worth trying! Obviously an unlocked bootloader is needed for this (Magisk).

And I came from 10.3.6 to 10.3.7 ... Are you noticed my issue while playing pubg ? Even from previous versions ? When I bought the phone 2018. I never encountered any touch issue I even tested with every thing even bad aiming (auto move scope) which showing In YouTube my phone did not have it

The chanlog say they updated the security patch, but I see most of user update to 10.3.8.0 saying they fix something about sms, touch lag, etc that not fixed on 10.3.7.0...
You can try from updater settings to see if it fix your issue, tapping maybe 10 times on logo (number 10's image) and press on 3 dot and update manualy, then choose the file you have downloaded (this link what I shared is from XDA guide).
EDIT: I'm on 10.3.8.0 EU, flashed today from PE+, clean Flash + Magisk 19.3, with F2FS, no issues found yet,

Thank you for your kind help.. and yeah I just upgraded to the new version 10.3.8, and yeah it's bit improved but still not solved 100%, first two match I played I felt playing on iPhone screen , and still getting here and there touch issue (cannot move aim smoothly for like 0.1 to 0.5 seconds ) when enemy in my face and I am firing at him.. I am still confused does this freeze because of touch or rendering issue (fps) or game issue,, because my touch works very smooth on blank screen for a test

Maybe you should try OOS rom the 6T build stable 9.0.13 .. i played pubg a lot and i can't find any issues at all regarding ghost touch. hope that helps

If you use full screen gestures disable them before playing pubg it might fix bad aiming issue. or if your bootloader is unlocked you can try custom kernel like twisted kernel with different nvt touch drivers.

Same problem, Any easy solution?
My screen also freezes when playing PUBG. Sometimes it happens frequently, sometimes it doesn't. Recently bought Poco F1 and I am on 10.3.7 Firmware. Both LOS and PE+ are showing same screen freeze issue. When playing PUBG, Screen freezes for 3-7 seconds.
I wanted to try more ROMs but they are on cheap ass SourceForge servers. Showing more than 5-6 hrs ETA, which sucks really bad :crying:.
If 10.3.7 is the issue, can I flash 10.3.6 firmware file (downgrade) and then install latest Pixel Experience? Will it work? I don't want to install MIUI again.

well, mine only freezes 0.1 to 0.5 seconds (but still its major issue when playing FPS).. try these steps if you did not :
- disable all gestures (3 finger and etc)
- update firmware to the latest 10.3.8 (if you did not get it already, change region to Philippine ) as latest firmware gotta some improve but not solved it

Update to 10.3.8 global stable no ghost touches

Same problem with miui 10.3.8
I've installed latest firmware ie 10.3.8 and encountering same issue. I made a seperate thread cause this one was dead already.I'm using miui 10.3.8 and tried many custom roms.Still problem exists.Anyone has found any solution yet?
PS - My poco phone is brand new,bought it like 2 days ago?

Poco X2 Touch Issues, Just me?

I had already made a similar thread(https://forum.xda-developers.com/poco-x2/help/backspace-virtual-keyboard-missing-t4069481) but I did not want to revive that or change that, maybe Mods can delete the old one.
Anyway, I am facing touch issues with the backspace but after some testing, I found out that it is bottom two corners. Topside is hard to diagnose.
I am linking a video showing these issues.
The problems I faced are
1) Backspace has some lag compared to other keys
2) sometimes backspace does not even register
If you watch the video you will see that sometimes even though touch is being acknowledged there seem to be some software edge padding or something which does not let the UI react to the touches, or it may be a hardware issue, idk. In the video, while touching at the corner you will see some gaps in-between touches which are actually totally unregistered touches which come as gaps in between touches.
Do you guys also have this issue?
App used : Multi Touch Test
Watch video at 0:15, 1:35, 2:55

@tinted
Your touchscreen looks fine cuz it correctly displays white dots you touched.
I guess Miui ignores touch events if Miui thinks there's not enough touched area.
I think Xiaomi may adjust it in the future.
I tried that testing app, my K30 shows same with your video.

Question Ghost touch issue

Hey guys!
I'm currently on ArrowOS 07.09 build with firmware 12.5.1. In the last 2 weeks I got ghost touch issues quite frequent. The phone starts to recognize touches crazy fast without me touching it and doing random things. I have to lock the phone with the power button to make it stop.
Does anyone else have or had the same issue? Is it a hw or sw related issue in your opinion? Any tips, ideas, working methods are welcome to make it stop.
Thank you!

It's mostly a SW issue , but it can also be a hardware issue(extremely rare),change the room to pixel plus UI 3.7 most stable(tested by me).
edit: also less bugs than others and very fluent.

I had the same problem. The solution is to turn off the Game Turbo app. Your problem will be solved.

Mine problem is solved by send it to service center. They replaced screen module.

Reporting.
For anyone facing heavy ghost touch issue, you might want to try indonesian miui 12.5.2 rom (rjuidxm)
Previously I got ghost touch on xiaomi.eu 12.0.4, 12.5.1, 12.5.2 to 12.5.4, few arrow OS version, to the point that I got tired of testing backing up restoring and doing clean flash everytime, because this is my primary phone I use for daily driver
But now I have used miui 12.5.2 ID for 9 days and haven't faced any ghost touch.. I also always turned on show taps on dev options so that I'll know if theres any ghost touch, and theres none so far (I have 6/128 unit with tianma panel)
But there's huge performance drop in this rom, game that I play (PGR) have noticeable frame drops where theres none before, others also reported lower performance on genshin impact

i dont have such issue
at least i dont notice it responding to "something" when i just leave it on table
btw, clothing contacts are also contact

software my friend , i write it fast

For me, it has helped now to set the refresh rate and the screen to 60 Hz. We'll see for how long. All other activities did not help, including the game turbo exclusion.

Unfortunately, but with the 60 Hz refresh, the touch has gone crazy once, but it probably happens less often

well it depends on what screen you have, if it's tianma the ghost touch is "normal" and will only get worse because is hardware related, if it's Huaxing it's probably software related or (very bad luck) defective screen...
you can know your screen:
If you are on a Custom ROM or have installed Magisk:
1. Download Device Info HW application
2. Tap on 3 dots in the right corner of the application
4. Restart the app
5. Check LCM (above touchscreen)
dsi_j20s-42-02-0b <- CSOT/Huaxing
dsi_j20s-36-02-0a <- Tianma
If you are on MIUI without root:
1. Open your dialer and enter: *#*#284#*#*;
2. Open a File Manager, go to ~/MIUI/debug_log/ directory, you should see an archive named bugreport-yyyy-mm-dd-HHMMSS; (Date and time when bugreport was created)
3. Extract that archive, then extract another archive which was in bugreport zip, its name should look like this - bugreport-vayu_global-RKQ1.200826.002-2021-05-27-13-32-52.
4. In bugreport-vayu_global folder open dumpstate_board.txt and type in search tianma. If it's found, you have tianma, otherwise huaxing.

Thanks. I checked my tianma. I found such a coincidence "MDPPLATFORM_PANEL_TIANMA_NT36672C_J20S_LCD_VIDEO" How do you think to advertise the phone?

Well there is many reports that it fixed with MIUI 12.5.5.0 global latest update. ( confirm it, please!?)
For me never happened "tianma".

Jestem na miui 12.5.2.0 EEA i nie ma jeszcze aktualizacji do 12.5.5.0

yes my phone update the MIUI to 12.5.5.0 and everything its good and smooth but I'm a little scared, if another update ends up breaking the device. On the other hand, I activated the option, to see the touches on the screen through the developer options, and detect that when I use YouTube and try to put a video in landscape using the button in the video, a single ghost touch appears in the middle of the screen, it does not affect at all apparently, but it seems to me that the ghost touches were not corrected correctly or in its entirety.

General A way to fix ghost touch (Poco x3 pro 8gb)

Hello, I have 3 poco x3 pro phones among my friends, we were looking for a way to remove this ghost touch and I think we've done it .. We had a week with all settings and there is a solution. Turn off miumi optimization (in developer settings), reset the phone, then download another launcher we downloaded the nova launcher and uninstall my launcher then reset the phone again and .. No ghost touch for 6 days !!! And that's on 3 phones. We also have a setting for 60hz .. It's worth trying, maybe it will help you too

Reset? Like Factory Reset?

reset or reboot the phone?

Reset means? Factory reset or reboot?

Update to 12.5.5.
I have 2 days in xiaomi.eu 12.5.5 and finally after 2 months the ghost touch has been dissapear.

This happened to me twice, I got moisture trapped in the crevice between the jelly case and the screen. The issue went away after I disregarded it and just went on with my daily life. It's the small things that gets the best out of us, but don't let it ruin your everyday life.

Update your software miui

Hi, I had the same problem before. I tried all the hints about developer settings and so on, but nothing really helped, it always came back after a little while.
I had a feeling it had to do something with high activity on the display or touch. In my case it often happened after lots of activity on the screen.
I disabled a background I had running, Earth 3D, and now the ghost touch effect is fully gone.
The rest of my system is pretty normal with latest original Poco launcher. So here I would say it is a firmware / systembug and some software might be incompatible at this state.
Hope this helps to find a temporary solution for yourself until Xiaomi delivers a solution (lets see how their support takes things serious)

Same here.

till in 12.5.4 i disabled the game turbo and used microsoft or other launcher, and that had helped me with the ghost touch issue. 12.5.5 doesnot have such issues.

On mine, i send it to service center. They replace screen module.

Installed another launcher, ghost touch seems to be fixed. Seems like the ghost touch is a software bug of the poco launcher.

This flashable ZIP is totally unrelated to the screen. It contains modified drivers for the fingerprint reader.
The only thing it could possibly fix is scrolling issues when touching the finerprint reader. But if you have actual ghost touches on the screen this won't help you.

Load the no gravity kernel for arrow os for me it fixed my ghost touches, you dont need to tweak just load the kernel as it is.

Can confirm. Installed No Gravity Kernel (v3.0.1) over LineageOS 19.1 and no ghost touches since.
Update: One full week, zero ghost touches.
