Some info about 8.12.7 with touch issues

The UI and touches have become far more smoother and responsive after this updated BUT also comes with another issue.
Multi touches/Ghost touches now VERY NOTICEABLE and screen freezes always occur and for a temporary fix you have to lock and unlock your phone. So when playing PUBG those ghost touches will mess up your aiming example when moving and aiming together suddenly your aiming aims to the sky/ground/random places with no explanation. Also the nav buttons and the middle area sometimes doesn't register any touches and this happened around 8.11.23.
8.11.15 =probably have the less multi touch/ghost touch issues but have some sort of delay around the edges/keyboard lag
8.11.23 =fixed the touch delay on edges/keyboard lag but multi touches and screen freezes is more noticeably.
8.11.29 =same issues as .23 except it's the issues is getting worser + screen flicker yay
8.12.7 =touch and UI overall is much smoother but issues from .23 and .29 is now getting out of hand and playing tap intensive games like MOBAs and drums is heavily affected. PUBG also keeps aimiing randomly at the skies/ground when aiming+moving
I wish the devs bring the touch edges delay fix back to 8.11.15 and see how it goes
I hope the next version fixes the multi touches issue and screen freezes also

On 8.12.7 All the touch issues are solved.

Agree with every point. Plus there's lot of typing lag & freeze on Gboard now
If you're on Xiaomi forum/beta group please raise a issue with all these details.

Mine is China Variant around September batch and clean flashed 8.12.7.
Still doesn't fix the screen freezes, multitouches/ghost touches and screen flickers
But when I used 8.11.15 never had screen freezes, ghost touches error. Only touch delay lag.
I suggest your should try tapping intensive game that involve tapping on the edges like drums or sthing to check your phone.
Some people claiming it's fixed but somehow don't even know what those touch issues are.
And I'm a poco fan

For forum just google miui forum & log in with MI account.
Even i'm not on closed beta so i dont know about close group butvyou can find one telegram ground by googling POCO Official telegram.
And last thing is to tag poco team & jai mani on twitter with issue. It works many time s

no touch issues here
pocophone f1
6gb
128gb

As a non gamer I must say that touch seemed fine to me until flashing 8.11.29 (previously had 8.11.15).
Now the touch response seems really laggy and typing on Gboard became highly frustrating.
I've read in forums like a dozen times every week people saying that the next build fixed all touch problems, but to me, it's worse than ever.
Hope the next build fixes this, or I will just revert back to 8.11.15 until they can sort this out, assuming that the problem is not hardware without the expected quality.

Latest is 10.3.8. Maybe now need manualy update because if I'm not wrong, they didn't put this on OTA yet.

I just checked it now. Yeah 10.3.8 rolled out in September 21, but I still did not get it . And it's just a security patch nothing to do with my touch issue isn't it ? 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

Okay, this is weird. Which version is it? And did you have already tried to reset your device? If it's still there it's probably a hardware defect.

Right, so no fix really... disappointing as the cameras are impressive

My device came shipped with Android Pie Based Miui 11, no screen weirdness. Just after the Android 10 updates that ghost touches appear. So I guess it's just software bug.

me too, sure software problem.

Thanks for the feedback, if software-related were you able to roll back to fix this?
Happy to try a workaround as I'm very reluctant to send it back..

worth a try though, but unfortunately Xiaomi didn't provide stock ROM specifically for my region so I left with no choice

Completely puzzled as I did a Factory Reset via Recovery and haven't seen the issue for past 2 days, I've left the screen touch tracing on and no 'ghost touch' was recorded..
so I don't know what to believe anymore, got an open return ticket but would hate to send it back without needing to..
how can I make sure issue is gone?

Hi, i had this problem 3 weeks ago, temporary solved with hard reset, worked perfectly until yesterday night when this problem went back.
Hard reset again, problem still there.
Someone solved it permanently?
It is really weird because, if i turn off/on the display, sometime works sometime not :S

The phone came with Android 9 and I started to face this after updating to Android 10. The issue is not extreme as shown in the video, it just the touch becomes slow to respond and hard to type fast with the keyboard. Turning off the screen and turning back on solves it temporarily sometimes.
I tried disabling on screen fingerprint and the problem seems to be reduced now. Definitely a software bug

I'm using Mi note 10 lite it also has same problem. Sometime touch freezing and after press power button automatically fix. Some time need to restart. And also one person told me he is fixed by this issue by turned off fingerprint sensor.

I have the exact same problem as you, slow to respond and hard to type. Need to apply more force on the screen for it to respond. This happened randomly throughout the day but are more common during night time for me.
I think it has something to do with the screen lock pin or fingerprint, by changing the screen lock from ie pin to pattern or turning off fingerprint print seems to temporary fix the issue. Another solution is to reboot the phone. I'm using Note 10 Lite btw.

Try switching off MIUI optimization under Developer Options and restart your device. Then switch it On and restart again. This workaround solved my issue.

This fixed the issue for a few days and it started to reappear again. When the issue appears, if I turn on Game Turbo for any app (eg: WhatsApp) that particular app doesn't have this touch issue. Looks like a software optimization or battery optimization of MIUI is causing this issue

Scrolling problem on android 11

Hello
I have a problem with my f2 pro. After updating to android 11 I got some weird scrolling problem. When I'm scrolling it suddenly stops and I need to take my finger off screen and put it again. I'm attaching video with that problem.
Rebooting phone helps for a while but after a while the problem returns.
My current miui version is: 12.2.4.0(RJKMIXM).
I don't know if it is software problem or maybe hardware issue.
Thanks for your help

deleted.

I have the same problem as you have as. It started after the phone was upgraded android 11. As you said rebooting the phone is solving the problem temporarily, then a few hours later it repeats.
I think it should be software problem, not a hardware problem.
Anyone else have this problem?

Hi, i reset the factory settings on saturday. It's solved on that day but today (4 days later) i have the same problem again. I think it should be android 11 problem, it mustn't be hardware problem because it started after android 11. And it's very annoying. I have to restart the phone after i see the problem.

Is it possible that it's one of the apps that you installed causing this?
Did you try to replicate the problem using your phone in safe mode (without third party apps)?

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

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".
Regards

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.
