[Q] Ghost Touches - Xiaomi Mi CC9 / Mi 9 Lite Questions & Answers

Sometimes, when I wake up the phone, some ghost touches occur and those touches slide down from the right corner and back into the corner. this event repeats continuously and quickly. I turn the screen off and on again, everything is fine.
Sometimes a ghost touch occurs in the right corner, so I can't control the phone. I turn the screen off and on again, everything is fine.
This problem started after upgrading miui 12 globe rom from miui 11 globe rom using TWRP. Actualy i dont know the exact time.
I tried evolution rom but the result is the same. I tried the build.prop codes (touchcalibration, touchsize, touchpressure ...) but no progress.
If this is a hardware problem, why is it temporarily resolved when we turn the screen off and on. hardware problem should always be ghost touches.
Any solution?
Thanks in advance.

I have the exact same issue using Masik 14.0 but honestly it's not that annoying so far.

I've been having the same issue, I believe.
At first I just rebooted the phone and everything was good. But now it's happening more often and I simply lock and unlock the device and most of the times the problem stops.
I have the "MIUI Global 11.0.3.1" and haven't flashed anything so far, so I guess that's not why it is happening to you.
I've read somewhere on the internet that it would help to disable "MIUI Optimization" on the Developer settings. I've disable it today, but the issue already happened afterwards, so it doesn't look like a solution.
If anyone has further information on how to solve this, I'd like to hear it. It's not a big problem, but starts to be annoying, especially when you're writing or trying to do some important task.

I tried everything and decided that is the hardware problem. I relocked bootloder and installed stock rom. And sent it to service to change the panel. Now i am waiting…

No. I am not agree with you. I turned to miui 11 stock rom and locked boot loader and factory reset. Ghost touch is still here.

My panel has changed, and there is no problem any more.

Hi, i have the same problem. Are you sure it's a hardware problem? After change the touch display, problem are disappear?
Thank you

[Q] HTC One top touchscreen problem - Bug or Hardware fault?

Hey,
I have an HTC One black - stock os - UK unlocked version - after 4.2.2 update.
I've got a strange problem regarding the top of the touchscreen. when the phone is horizontal, the top bit (between the top bar to the first widget) is not working. the rest of the screen working fine. when I pick the device up, the screen is working fine 70% of the time. as a result, I cant open the notification bar and it thinks that I'm clicking or re-arranging my widgets.
It's weird because IT DOES work 60% of the time.
1. did any of you experienced any of this before?
2. What do you think it is? software or I have to replace the digitizer?
3. Is it just calibration problem? I tried to calibrate the device using the keyboard screen calibration and it didn't do anything.
Thanks!
Eran.

Bump for more responses
I
I just started experiencing this same problem today as well. I was on a Google Edition 4.3 Rom for about 2 days, Viper 3.2 I believe and everything was initially working as it should. Suddenly I began experiencing the non responsive status bar. I cleared data & cache, fixed permissions, and even tried a factory reset with no luck. I then reinstalled the Rom and the problem persisted. I then downloaded and installed black jelly Rom along with a complete wipe of the entire storage after transferring important data to my PC, but the status bar was still unresponsive and it appeared the top 1/4 inch of display had a digitizer issue. I tried to restore an older backup of Venom Rom running Sense and I still had no luck, until I went into the browser so that I could rotate into landscape to see if I could access it from this orientation (don't know why that didn't cross my mind sooner?) After I pulled the notification shade in landscape I left it down and rotated back into portrait mode and drew the shade back up slowly, following through with the gesture all the way to the top of the display. Then the functionality from portrait was restored! I believe this is a software bug of some sort, but I'm contemplating returning it to stock and relocking the bootloader to return it. I'm actually using the Tmobile variant and it's only about 30 days old. My insurance will cover a replacement for a faulty unit, but who knows if will happen with another? After a Google search I discovered this was an issue that surfaced with quite a few One X's as well, so I'm thinking it may be a bug that's consistent with some HTC hardware of a different variants? Any updates or insight would be appreciated.

Screen and Sound Issues

Hello,
I am not sure what is causing my issues. Once in a while, the top left screen corner (about 0.5" x 0.5") is not registering my touch and there's no sound from the device. The phone is a N920I rooted with arter97 11.0 kernel. My temporary solution is to clear all background apps. Try googling the issues but to no avail. I also tried opening all apps and I could not replicate the issues. The phone has to sit idle for a little bit before it happens.
Anyone with similar problem?
Thanks.

Phone frequently hangs or touch screen unresponsive

I'm experiencing hangs or touch screen unresponsive, I think its the touch that stops responding unless you lock and unlock the phone.
I have three weeks with the phone and started yesterday right after a Factory Reset. Before that, it never happenes.
Today its better but still happen
Attach an image with the touch's firmware version
Has it happened to you?

same thing happens to me from time to time, i have the phone for 8 days now, it started maybe 3 days ago, screen unresponsiveness happened maybe 4 times to this date
temp fix for me was downloading Google GO files and using it to delete cache, it works for now, no screen freeze up to this point
I think is not the same issue, I refer to touch issue thats come unresponsive some times until you lock and unlock screen. Now I'm testing android P which have another firmware for the touch panel. I will report later if dont presents the issue.
I installed the preview of the Android P developer and used it for two days and after a day of use I had the same problem, very disappointing, I went back to version 8.1, I do not understand why this happened, I never hit it, threw it, nor nothing. I was very carefully with it.
Has this issue been fixed yet?
We have a few of these phones in our family and one of them is doing this sporadically, several times in a row and then it's fine for days.
I can't see a pattern as to when it happens though.
Short Question : any of you using the Nova Launcher? Ive got same problem but using the Nova Launcher since years. Yesterday i did a clean Nova Launcher (stable) install and not taking my Backup file... And my Problem with hanging (Touch panel not recognized often my Touch) seems gone. Dont know why but after testing a whole of things im trying the standard Launcher and it works better.. So i did a clean install of Nova.

I had a Novatek V7 version with firmware V1.017.20 with unresponsivness of the screen when laying and got it replaced. Now it's also Novatek, but with Firmware V1.017.16. what version of Android you have? I am using 8.1 Oreo. Does the android update change the firmware version of the screen?

Hi guys, do you guys Enable or Disable "Tap to wake" function? If not, try enable that function, maybe that help.
Same problem in my Nokia 5.1 Plus. automatically touched at top of time side and battery indicated area. and i cant open notification bar.
I turned ''Tap to Wake'' on and my screen has worked perfectly since then. So i think this is definetely bug, not HW problen.
has anyone managed to solve this? its diving me nuts since the past few weeks and i dont know what to do with it. I would try to fresh install the OS but if that does not fix it, ill loose everything (game saves and such) but dont fix it.
i noticed sometimes the screen does some kind of refresh and then it starts working again. But mostly i have to lock and unlock to get it working again.

The only thing that worked for me was returning the phone untill the screen was replaced.
Everything else I tried (reset, reinstall, change settings, ...) led to the same problems after a while.

Touch response delay when waking up the phone

I've got the 8gb/128gb version of the phone the last weekend. I'm having this issue where the phone is not responsive to the touch for about 1~2 seconds after I wake it up (either by double-tapping the screen or pressing the power button).
This happens after the screen is off for a few minutes (even if playing music in Soundcloud/Youtube Vanced). It'd turn on the screen but I can't interact with the screen right away.
I used to have a similar problem with my Razer Phone 1 and it happened whenever I tried to hide the navigation bar or use a different navbar/gestures. I have gestures enabled in the ROG 2, but not sure if it's related. Also, I think it came with WW ROM, I don't know if that'd matter.
I'd really appreciate any input from you guys on how to solve this. Thanks

I've got same phone on the latest ww rom (there's an update, might help) and haven't seen this yet. So you use double tap to wake? Any screen off gestures? Would be interesting to figure out which feature is misbehaving

It doesn't show any new update when I check. I believe it's because I dont have the CN ROM. Yes I do use double tap to wake. I will disable it and use it during a day to see if it change. If not, I'll try using the navbar instead of gestures. I haven't set up any screen off gesture. I'll report back if I find something

This also happened to me when I converted to WW ROM, and to many others as well. It affected my gaming experience so much so I converted back to CN ROM. I will be using the CN ROM until this problem is fixed.
Guys can u tell me where to set the double tap to wake the phone? Thanks
Found it. Dang all this time I didn't know this exist
Nb I tried using it and my phone is working great and fast. I'm using ten cent version.
It has nothing to do with what I mentioned. I think I'll reset my phone or convert it to the CN Rom
I have the same issue unfortunately - A 1 second delay when I tap to wake (screen kinda just freezes for a split second then turns responsive again).
Not a big deal, but wondering what is the issue.

I still have the same issue. I went from WW rom to CN rom, but it did not fix that issue. Most of the time does not happen, but sometimes it can freeze up to 5 seconds, which can get quite annoying

Mmm. Hey, I am currently on Android 10, and the problem seemingly is gone (actually it kinda looks like there's a split second animation which makes the delay unnoticeable) - Give that a try to see if it helps?
5 seconds is horrible!

Im not sure about going to Android 10, is it still a beta right? The issue disappeared for me the first days when I changed to CN rom, but it came back a couple of days later :/
To update - Am on Beta 6 - So far so good. The problem hasn't come back yet. Only catch is double tapping is a slight bit less sensitive than before.
Once the official Android 10 release is out, hopefully that would sort you out for good!

Question Redmi Note 10 Pro started to occasionally unlock itself when receiving notifications

Since the 13.0.4.0 update there were a couple of times when a notification opened the phone's home screen without me unlocking it rather than just lighting up the screen.
Is anyone else having this too?
Yes, I too have the same problem with MIUI 13.0.3.0

That's basically one version before the current one? Because I don't think I had this bug on the MIUI previous to 13.0.4.0.
Has it started to happen only during the last couple of weeks for you or ever since you've installed 13.0.3.0?
I don't know if it's the penultimate version, because it doesn't show me any available updates, so for me this is the latest version available
Yes I have this problem since the update... Besides this problem the phone also started to be terribly slow, it freezes, the screen lights up for no reason, and besides I have some problems also with the vibration due to the pressing the keys, it stops working and then starts again when a notification arrives.
Worst update ever.

Strange, do you have some local version of the phone? The latest update available for me was MIUI Global 13.0.4.0 Stable (SKFMIXM).
I don't know about the rest of your issues, stuff like Netflix hanging up occasionally already happened on earlier versions, perhaps it's a bit better now actually.
Also it seems the grey uniformity of the screen is slightly less blotchy now, which doesn't make sense for a software update to improve. Maybe the OLED getting older reduced differences in voltage response between groups of pixels?
good evening ,
Giovy 52845:
I would recommend resetting the phone to see if that fixes the problem.
Yes i have the same issue on miui 13.0.3
Hello there, registered an account just to write here, I had the same issue, trying to change the notifications, unlock mode, even reseting my phone and all settings I could to fix the unwanted unlock, nothing worked.
But lately, I uninstalled the Vanced Y*utube apps, wich is no longer suported since late march if i remember right, and boom, after a restart of my Redmi Note 10 pro (MIUI 13.0.4), didn'tunlock on notification since 2 weeks!
Hope this help.
I have the same issue, and I am currently on MIUI Global Stable 13.0.8.0 (SKFMIXM). The problem is intermittent, but it happens often enough to be VERY TROUBLING. I reset my phone to factory settings but the problem persists. Looking at this thread as well as other forums, I see this has been an issue since MIUI 13 was first launched.
Note, THIS IS A VERY SERIOUS ISSUE !!! IT IS ESSENTIALLY A SECURITY FLAW !!! Xiaomi should treat this with the HIGHEST PRIORITY !!! I use NFC for payments. If my phone gets stolen, then there is no immediate protection against fraudulent use of my Wallet since it can be unlocked without any form of authentication ! If this ever happens, and Xiaomi is not proactively and very expeditiously resolving this issue, I will hold that company responsible !

Yup, it's still happening and I realized eventually that the issue is the phone itself simply doesn't lock itself sometimes although the display is turned off. When it happens the fingerprint sensor won't open the screen as it's not actually unlocked, you need to press the button and you can see the screen lights up without actually going through the unlock process.
+1
Currently, I am facing the same issue on the latest Xiaomi.eu ROM V13.0.12.
Earlier I faced it on the stock MIUI after the V13 update.
