Touch issues (ghost touch and screen freeze) - Xiaomi Poco F1 Questions & Answers

I got my Poco recently and having problems with ghost touch on the top around Notch, and that bothers me mainly in PUBG Mobile.
I already tried several methods like disable functions, hard reset, etc and nothing worked. Flashed Custom ROM and the problem persisted, in this I had a suggestion to use Custom Kernel and really the problem of Ghost Touch disappeared but now i having freezing of touch being necessary to turn on and off the screen.
Because for this bug, returned to the stock rom, kernel, etc...
I would like to know if this is a Hardware or Software problem and how to fix this.
PS: Sorry my english. :v

replace your display panel if it is not nvt, get nvt panel and all problems will be solved.

I will change it as soon as can, if anyone has more suggestions on how to solve (software) I will be grateful.
When I change the display, will return in this topic to comment the results.

Did they also update your ROM/firmware?

pocophone should get stock like os, realme started realme os to prevent these bugs, with stock ui instead of memeui we can have all sorts of problems gone..... need support from poco team.

ghost touch,screen freezes and touch lag is a mixed bag. your device issues can be due to a hardware problem but if touch problems on your device vary with different roms and kernels then its probably a software issue like in my case......i started having screen freezes two weeks ago after 7 months without problems but it mainly occurs with pubg(other heavy games run fine).....when i flash miui 10 or custom roms with recent vendor and kernels i get all kind of touch problems with pubg and phone menus BUT when i flash miui 9 oreo i get occasional touch freeze with pubg while ALL other games,apps run fine!
panel is fts (december 2018) and am almost sure xiaomi has a software fix but they are busy with their new toys

I had Ghost Touch problem on my Xiaomi mi9 in Call of Duty Mobile and PubG.
This is the only solution which fixed my problem:
xiaomi.eu/community/threads/xiaomi-mi-9-ghost-touch-issue.51043/#post-503263
1. Open settings
2. Activate developer options (My device > Tap 8 times on "MIUI-Version")
3. Settings > Additional Settings
4. Developer options
5. Disable MIUI-Optimizations (at the very bottom).
6. Reboot

Touch screen Re-calibration

To the people of Turl's and Jokersax' CM9.
I have a touchscreen re-calibration app, I just tested it out and it seems to be working perfect. Don't hold me to it, but i think this is a pretty good temporary fix.
I'd love feedback, i didn't code this but after a few searches i was able to realize this is a universal fix for touchscreens that have been acting up.
Special thanks to gojimi. At least i hope.
Can you link the source please.
Cheers!
Just a question, do we actually need touch calibration after flashing cm9? Cause AFAIK, when I tried the jokersax rom, the only problem I had was app incompatibility and APN errors...

I know what you mean, sometimes homework takes away most of my time too. But just use CM9 as your daily driver, and you'll be well informed on any issues that will occur.
This actually screwed up my touchscreen..anyway to uninstall?
Hi,
I have a software issue with my touchscreen :
1/ Got stock ROM, then CM7, then CM7-Neutrino-2.2 => screen was OK
2/ Installed CM9-Turl-v8 => an unresponsive horizontal line appeared, around 100px high
3/ Tried to come back to CM7, CM7-Neutrino, CM9-Joker-0.4 => bug still there
4/ Tried this calibration app, but couldn't click the button because it was under the unresponsive line, so turned the phone into landscape or upside-down to execute => bug still there
5/ Flashed PDS fix => bug still there, fear of a hardware issue
6/ Installed CM9-Joker-0.5 with awesome Installer => touch screen goes totally crazy (phantom-touches), BUT the line is finally responsive !! So, le wild idea appears
7/ Retried this calibration app, this time in the right way => SCREEN FINALLY OK !!!...
8/ ... For about 2 hours... Now my phone combines 2 issues : a new horizontal line is unresponsive (thinner than the old one), and crazy phantom-touches happen really often...
I was desperate, but now I know my problem is software, I see hope ! Am I the only one to have this problem ?
Thank you in advance

Poco F1 Touch unresponsive/Lag in PUBG/Keyboard lag [workaround/Fix]

Hi I was facing issues with
1. Flesky Keyboard emojis cannot be touched.
2. UI Freeze*
3. Pubg
a. Joystick won't respond while parachuting.
b. Lags when another player is approaching me.
c. Some buttons usually the accelerate vehicle or the eye stops working or misbehaves.
d. Freezes completely* in front of the enemy player.
e. Freezes completely* at random places for a period of time and get back after I lock the screen and get back in.
*The application runs fine but none of my touch input gets registered.
On POCO F1 running MIUI 10 Global Beta ROM 8.10.25.
What worked for me.
1. Turned off 3 finger screenshot.
2. Turned off full-screen gesture
3. Turned off one-handed mode
4. Switched to google keyboard and turned off glide typing and gestures.
5. Uninstalled all touchscreen tester, repair and calibrate apps.
6. Cleaned Junk and reboot.
Results
UI lag and keyboard issues fixed completely.
Pubg Freeze fixed
Using game booster for pubg no issues yet.
Very rarely it does stutter and I know its because I use multiple apps (Texting..) sometimes while on pubg so I use the game booster to free up ram and it works.
Hope these help someone else facing the same issue.
I guess its the gestures.
PS: This is my first thread Its not an in-depth fix, maybe a workaround but if it helps someone then why not.
Update: Switched to stable miui 10.1.3.0 via updater app after factory reset. (Flashed complete ROM)
All the touch issues are fixed for me (I believe for many others in beta 8.12.13 also have them fixed. As the number of post complaining touch has reduced a lot).
Dirty flashing or ota updates were the reason for screen freezing/touch unresponsive issue in my case.
If you face similar issues as above please factory reset and flash complete rom again and don't restore old apps.
This can be done via updater app alone. Root or bootloader unlocking is not required.
Disabling Gestures made Gboard much better, indeed. Looks like there's no problem at all. But c'mon, Xiaomi need to fix it. Infinite Screen is a must need on this smart.
I will try PUBG Mobile now.
EDIT
Same problem on PUBG. Aim often just jump when you touch the screen. But hell, the keyboard is fast now!
I will go back to Infinite Mode anyway, theres no way to use Pocophone without it.
Thanks for the reply sorry that it did not work for you.
And yes without gestures its not very handy.

Thanks man. After reboot and turned on Infinite Mode again, surprisingly Gboard is working much better now!!
I'm typing really fast even with Infinite Mode On!

Does 8.12.13 really fix the slow touch issues?

I've read it from the MIUI Forums. Does this version really fix the touch response? If so, how can you rate it?
Yeah, so no more touch delays, touch not registering, PUBG aiming bug, screen freezes, screen flickers, and this is coming from a user that faced these issues about 2 months.
Now they only need to fix those multi touches/ghost touches and it'll be perfect as it's still there
So I guess not all is experiencing the issues you mentioned? I had the edge back gesture not working well before and the flicker, but I never experienced any ghost touch or input lags.
not everyone got all issues.... i only got touch latency which is fixed 90% what i can see now..... but they need to fix it further to make its smoother......
but somehow aiming in PUBG in 8.12.13 doesn't feel smooth and snappy 8.12.7/8.12.10.
Now they just need to fix multi touch and ghost touch. This happens when I use 2 touches and swiped them so hard.
Ghost touches always happen below the notch area and the navigation bar area
Just got the open beta 8.12.13 OTA, following are the observation :-
1) Keyboard lag is minimized.
2) Scrolling near edges is improved but still buggy near bezels.
3) YouTube picture-in-picture mode doesn't work in full screen gesture mode in poco launcher home screen.
4) Screen flickering in lock screen is gone but further need to be tested.
4) Icon refresh is still there when minimizing any app.
5) Back gesture now works properly when any app folder on home screen is open.
6) Tuch delay of back button of navigation Bar is gone.
7) Touch sensitive of screen is bit improved.
8) Something flower like icon is added in left bottom of lockscreen.
9) Notification icon is same it was in previous beta.
so far no ghost touch on my poco 8.12.13 eu

Dam. Now, I've to flash back MeMeUI again to test it. I'm happy using LOS16. I'm sure I'll regret flashing MeMeUI cause of the crappy cartoonist UI but if that fix the issues, that's more important for me right now.

Merging firmware into the ROM can fix sometimes. You can wait a little the LOS genius devs to take advantage the newer firmware/vendor files.
No, they still haven't fixed the bottom area latency. It's the same as it was for a couple of weeks.
For me the touch has got worse. I didn't have any touch issues on all stable ROMs I ran till this first stable Pie/Oreo rom. I say first Pie/Oreo ROM as it's the first stable Pie ROM but still using lib library from Oreo. I'm noticing that I'm making more mistakes typing than I was before so I feel it's over sensitive now

The Poco team said it themselves that they couldn't fix the touch in the latest stable release yet so it's probably the same firmware as in the earlier builds. Shouldn't feel any different.

I don't believe them at all. As I said I wasn't suffering from any touch issues and this latest stable ROM has made my touch worse
For those who get worse in the update,make sure you do a clean wipe before flashing.
I found that after doing a clean update,my touch is better. (Not sure if it is really working but installing Magisk also kind of making my phone smoother)
But for sure the touch latency is improved.
For ghost touch,i test with multitouch tester,no more.but in pubg there is still ghost touch (my character shoot randomly when my thump near the shoot button). However,can fix by separate the buttons a bit far from each other.Then,reduce the in game camera about -5 to -10 for each categories.i found the game is more playable that way.My guess is that somehow the phone screen sensitivity is high.
For me, as a regular user, I can say that the touch is worse than 8.12.10.
When I say worse, I refer to the up / down scrolling through pages / facebook / etc.
Other than that, I don't seem to have any issues

This is my last hope to get back to normal in Pubg please help if u know a solution

Well that notch issue is there. I think it will be fixed in upcoming betas.
I play pubg on my Poco F1 no problems. In the in-game settings menu, under graphics, scroll down to the bottom. What option do you have selected under non-standard screens? I have mine set to normal and don't have any issues with the notch. It blacks out the sections each side of the notch which is really only possible way to effectively hide the notch so it doesn't interrupt game play. Also Az screen recorder works fine for recording games

And I know about the setting
When I take screenshot a black bar is in the picture where the notch suppose to be
I want the notch I want to have screen there that's why I bought a phone with a notch
And I don't know what is the problem that it's like that and it's really stupid
But thx anyway
And my issue is that no one is talking about it so it's just left behind

I even changed the rom to lineage os and hoped that it will be fixed but apparently I was wrong
I hope more people talk about it so the developers came up with a solution and fix it
Yesss i hate it, i want the game to go into the notch and move icons so they arent lost, apparently it did before but the "fixed" it.
Does xiaomi acknowledge this as a problem do they even trying to fix it or this is only something annoying we have to live by ..
I also noticed that the game after life takes the whole screen under notch doesn't makes sense why other fullscreen apps doesn't

Well I wrote this thread and hoping more people talk about it till someone acknowledge it but it has been 3 weeks and nothing happened even the new update came and it's still the same and I'm not sure what's the problem Xiaomi or PUBG cuz I'm currently on lineage os and I noticed a lot of games and apps are like that they just don't use the notch it's just black but hope see someone talks about it
Cuz it's really annoying with screenshot recording the screen and have screen besides the notch but not be able to use it

Fix still haven't released only way to play full screen is to downgrade to oreo rom , i am facing the same issue it can be fixed by both mi and pubg but they are too lazy or unconcerned . Wait for next stable but chances are very low
Its fixed now .. after the new beta update 9.3.14 only for pubg but i'm glad to see the game take the whole screen now ..
Im on 10.2 .Problem is still there
Pubg runs at full screen again in the latest beta, the next global update should carry the same fix hopefully.
*Fixed* please install latest miui beta rom like 9.3.28

Touchscreen unresponsive after waking from sleep

I recently unlocked bootloader and installed custom ROM in my Redmi note 4(modo).After installing custom ROM touch screen goes unresponsive after waking from sleep.After restart the touchscreen works without any issues until the phone goes to sleep.The problem does not occur in miui.Only occur in custom ROM.Tried aosp extended,rr ROM,pixel experience ROM,ion os ROM the problem occurs in all above custom ROM.All the above ROM are pie based.
that is weird for sure
i didnt face any thing like that before
Yes that is very weird
did you changed your display panel for some reason?
if yes then it might be the issue. i have also faced this screen freeze issue on mido on which i changed display on my own from alixpress after broken screen,may be the lcd driver did not match! Try Havoc OS. it might work as its working for me. Weird!!
Hey i have solution for that
Just open back panel of your device remove the battery connection and connect it again & reboot again
(Note : before removing back panel 1st remove Sun tray)

Thanks Man. I too had the same problem. I repaired my broken screen from a local shop. And after installing custom room like AOSP extended and pixel experience, I faced the same issue. But after every restart it worked fine and screen freezed after lock down again. Now I have been using havoc os for nearly a month. Freezing occurred a few times for the first two or three days. But now it works like a charm. I don't know the actual problem but this works for me. Am using havoc os 2.4. Android pie version.
