I have that same problem. Could you help

Happened the same issue to my Mi9. Multi touch was working normally but suddenly it stopped working while I was zooming on a web page. Then I made a factory reset but still didn't work. Today I updated to Miui 12 hopping the problem would be solved but still no success. I think this bug is related to Android 10 as I saw elsewhere someone rolled back to Miui 10/Android 9 and things got to normal. On the other hand this is not a hardware failure for sure since multi touch keeps working normally on apps running in game turbo mode.
So, has anyone found how to kill this annoying bug?
Thanks for any help.

ive been searching everywhere how to fix this. i already email xiaomi about this issue. still didnt find clue how to fix this bug. still hoping that xiaomi will fix this issue.

This issue is a shame for Xiaomi!
As far as I know the only solution is to downgrade to Miui10 and stuck on this version or take the risk to upgrade to Miui11 (not recommended for obvious reasons) or the fresh new Miui12. So far I've been using the "turbo game" thing to workaround the bug. I had to install some alternative apps from Google Play (such as Chrome Beta, other gallery app, Google Maps Go...) to use instead of the stock apps so I can use them with "turbo" and get pinch to zoom working. This is not the best way to solve the issue -- the ideal is to get multi touch back working again without the need to resort to any tricks -- however it works very well. Maybe one of these days I'll get some patience to setup the good old Miui10 again...

i also have this ghost touch on the upper part of the screen. it came same time as the multi touch issue. it cant even fix by game turbo. i cant even play games normally like moba or fps game. i dont know if its just me have this ghost touch issue. its a big shame for xiaomi flagship phone?

No news about this issue? Everything works fine with Pixel Experience in my MI9 but multitouch. I remmember I solved another problem (auto-rotate didn't work for the display) and I solved it flashing only last version of "persist.img".

Same here bro!
I bought my Mi 9 in February and everything worked well. I also upgraded to MIUI 12 with no problems at all, then suddenly multitouch stopped working.
If I flash Pixel Experience will the problem be solved?

No way, Installing PE doesn't solve the problem.
I'm going to try it with new kernels and FWs.

Try to flash MIUI 10... I read somewhere it should work, because MIUI 10 is built on Android 9, which doesn't have this issue

same i have this issue, i tried miflash. the only workaround are miui 10 and game turbo method.
also i have this nonresponsive part of the upper screen, right where most game analog button placed. idk if this "dead touch" is connected to this multitouch issue

This was the first and probably the last Xiomi I bought. Back to iOS. Bought a second hand iPhone 11 in mint condition. Working rock solid! Crap Mi9!!!

Have the same problem here!!!
Upper screen DEAD
Annoying ghost touch on upper screen
Have to type multiple times because It keeps ghost touching...
Can't sell the phone, because of these issues...
Miss my Galaxy note

Is there a fix to this issue now? GameTurbo enhances the touch so that multitouch works. There must be a fix to this.

[Q] "reverse" accelerometer, or app problem?

Hello all!
I have been a proud user of Galaxy Note user for a bit over a week now, and I am trying to test (in real app-world) if all the sensors are working correctly to be able to bring change it at the store if something doesn't work, since I'm eager to root my device and I probably won't be able to return it then.
Yesterday I installed the game AirPenguin, which uses accelerometer controls, and it seems all messed up. Basically what happens is that as soon as the game starts, the bird goes flying way left, even though I am holding the phone still. What I found out after experimenting a bit was that the game itself is locked to portrait mode, but the accelerometer works as if it was in landscape. Meaning I have to hold it in landscape, and when I then tilt it left, the bird flies left in game-screen, but left is down from my point of view.
I was wondering if anyone else has seen such problem in this game or any other app, and if it is just a game bug or if there could be a problem with the accelerometer.
The stock accelerometer calibration works without a problem - when I tilt the phone left, the ball goes right, and when I tilt it right, it goes left (I suppose that's how it's supposed to be).
Thank you all in advance!
ME TOO
I'm facing the same problem on my Galaxy Note, I wonder if that happens also on other android devices or it's a galaxy note issue only?
i dont have the app, but is auto-rotate (that thing in the notification bar) turned off or on? try changing that to see if it fixes it?

Touchscreen or Software Issue?

Hi guys! I just upgrade from a Nexus 5 to S6 Edge. I am having an issue with this new phone not sure if it is affecting everyone or just me... :/
I am having an issue to swipe on some applications. One of the application is Swiftkey. I find it very hard to swipe to delete whole word. (You need to have Swiftly Flow disabled.) My music player (ZPlayer) i also hard it hard to swipe to skip songs as well. Is it just me or everyone is having this issue? I have used those touchscreen tester application and find my touchscreen to be fine.

Hey man, I'm having the same problem, definitely a software issue as I tested the screen via *#0*# and it's working.
Any updates on your end?

No solution so far but just living with it... I am surprised that this matter is not noticed by many users yet. :/
Had a problem with swipes being interrupted and taps registering multiple times. Got the screen replaced through warranty and the problem is gone. The problem seemed to be caused by pressure making the digitizer make contact with some other part causing erratic touch response.

Xperia X Performance (F8132) Accelerometer failure & Screen Auto-rotate irresponsive

Xperia X Performance (F8132) Accelerometer failure & Screen Auto-rotate irresponsive
Hi All,
I got an issue bothering me since I bought Xperia X Perfomance (F8132) Mid June.
The auto rotate function failed after a while but everything goes fine after reboot.
When it fails, I use "Xperia Service Menu" -> "Service Tests" -> "Accelerometer",
then all X,Y,Z are zero and the ball just sticks and freezes at mid.
I bought from Taiwan and I can find 15 more people having the same symptom with me on 2 forums
( http://mobile01.com and http://gamer.com.tw ).
Hence I don't think it's only me and it's a common issue or common yield problem for Xperia X Perfomance.
I post here because I'd like to find more people with the same issue and raise the attention of SONY in order to find the root cause (i guess it's either over-heat causes this or accelerometer yield issue) and give a patch.
Now I'm using a APP "Rotation Control" to workaround this, but all photos cannot records correct orientation data and no auto-rotate is kinda inconvenient.
For a flag-ship and high-priced cellphone for SONY this year, it is very disappointing to me. :crying:
Version: 35.0.A.1.227 and 35.0.A.1.238 both occur

I also have that problem. No more auto-rotation after a while (1-2 days) . Only a reboot fixes that

Thank you for letting us know.
It shows it's not a regional FW issue but a global HW or FW one.
I wonder if SONY knowing this. If not, we need to address this and push SONY to work it around.
And if it is not workaroundable, SONY will have a big problem.
I have the same issue on my Xperia X (F5121) bought in Sweden. Haven't checked the accelerometer but the behaviour is the same and reboot is only fix.
I have not had any problems with auto rotation, my accelerometer works fine but my touch screen is messed up

Can you specify "messed up"? I've had issues with the touch screen also, mostly that it registers a tap while I'm scrolling resulting in involuntary tapping on links. Also it often takes a while to start scrolling, as if the screen has a hard time recognising the swipe.
I have the same problem. The accelerometer stop working 15 minutes after reboot.
Help me verify if is caused by a third party app or not.
Use your phone in safe mode for a while.
I'm from Hong Kong, the accelerometer and its auto-rotation of my x performance has the same problem that it won't work until i reboot my phone.
I dont think that is caused by a app crashing when the problems occuring in all around the world.
The issue didnt come to me when I was not yet update to 35.0.A.1.282. Please notice this problem SONY. It seriously affected the satisfaction from user of the phone from your brand.
There is a topic on the Sony support forum - see here: http://talk.sonymobile.com/t5/Xperia-X-Performance/Accelerometer-stops-working/m-p/1158490#U1158490
At least they are aware of the problem. As soon as it happens again on my phone, I will send them my logs. I will report any development...
It seems that I uninstall the AR effects in my phone and reboot, it works again
Rotation fails
Hello guys,
I have the same problem. Yesterday it worked fine, but today, the auto rotate don't work. Very disappointing. Only a reboot can help but not every time.
Sony has to do something with it.
Gyroscope/Auto-Rotation Issue
Hey everyone,
I'm also having this same issue, but only since the most recent update from late September. When trying to make a pic display as fullscreen by rotating the phone, nothing happens, unless I reboot the phone. Then within day or two, it starts happening again. When I go to camera it loads up and STAYS in landscape mode, no matter what I do, even closing it out and clearing out the cache & force stopping it then reactivating it. It seems like a software issue that Sony needs to address PRONTO!
It appears another thread here on XDA is dealing with the same issue. I tried shenlong85's idea and it seems to have fixed the issue, but I need another day or so to make sure. If you don't hear from me by Sunday (10/23), assume it's been fixed. Hopefully the Nougat update we're all about to get any day now will permanently fix it!
The memory uninstall updates only prolong the issues. Seems like the firmware issue earlier on.
Nougat... When are u coming?

Well, we'll see. I am giving my XP 'til Sunday........if no more auto-rotate issues by then, then I will consider your idea to be gold. lol Of course, once we get Nougat, I'm hoping it will ensure that the issue never comes back period. As of this time, the issue has NOT returned.
I bought my Xperia X Performance from Kogan who sells imports in Australia from Asia and I have the exact same issues with my orientation and touchscreen. However my jumpy touchscreen only seems to occur while charging.

I tried shenlong85's idea, but less than 24 hours after trying it, I switched my phone from Portrait to Landscape to view a 16:9 widescreen pic I had in my Album, and it WOULD not auto-rotate the pic. So unfortunately this "trick" doesn't work either.
Just have to hope Sony includes a fix with the Nougat update we're about to get any day now from them.
I'm noticing now too that once the Auto-Rotate function stops working, so does Smart Call Handling. Have to swipe screen once again to take calls. Hurry up Nougat!! lol
I'm having the same issue and the only help I'm getting from Sony support is to factory reset my device :\ I'm hoping Nougat makes it's way to our devices soon. I really like this phone and this is a pretty big issue to have.

I agree Spencer. And yes Sony Mobile told me the same thing. I'll do a repair (which yes, includes a factory reset) only IF Nougat doesn't fix it. They say we're getting it "in or close to October", so I'm guessing it's gotta be coming any day now. Hopefully they include a fix with Nougat though and I don't have to do that. Getting tired of this BS with Sony. My Z3 had an issue where if I turned on Stamina Mode, it would 1) mess with my MMS (group/pic/video) text messages.........you don't know how many times I had to ask ppl to resend those to me and how much that sucked lol 2) Cause a "random" battery drain. Only fix was a factory reset. I FINALLY got wise and realized it was SM and kept it off. Found a great app called 360 Hibernation Master that did what SM was supposed to do but better, MINUS the buggy BS. But OF COURSE it doesn't work on any X series phone (at least not my XP), so I'm stuck with SM now. At least Sony Mobile FINALLY fixed that bug with SM so that's not an issue anymore. lol
It is a big issue, and it makes me not want to keep buying their phones.

Touch issues / Sensitivity issues after Nougat update

Okay so I wanted feedback regarding this whether someone else is experiencing this or not.
I have gradually observed during the last few days that a lot of my touches to click have gone unresponsive in Nougat. Initially it was something that I hadnt quite noticed but slowly the trend became obvious. Now dont get me wrong, this would happen a few times here and there with lollipop and MM as well, but the rate is far higher now on Nougat. Especially when typing on the keyboard this means mis-spelled words, missed letters, and accuracy is far worse now.
Has anyone else observed this or is it just me?
Just got my xcover 4 with nougat installed i have the same issue.
The sensitivity is low and i need to press a bit higher finger force to respond.
Even with sensitivity (glove mode) set to on things get worse.
I'm seeing the same thing. What is strange is that I'll see the button highlight/depress, but no action occurs. This is on multiple apps.
On what device/OS?
Sprint Note 5 on Nougat
Did you try gloves mode? Does it work?
the same for me on 920cd and the same iusse using S pen
I contacted samsung Greece about the existing problem.
I reported the problems me and you guys have and the tech support told me that your problems exist because you did not factory reset the devices before upgrading to nougat.
Anyone tried to contact samsung about the problem?
They dont know anything about it.
facing same issue screen lagging in note 5 sm-n920s also tried custom rom but still lagging in typing and scrolling on facebook
I have the same problem on my xcover 4 here!!
When I run the the touch screen test, touch screen responds well, but when I want to write a message or to scroll the home screen Its very annoying. It looks like software problem.
please help
Hi guys.
I have 2nd piece of Xcover 4 SM-G390F (first was change by seller for new one) and had the same problem. First 2-3 days all work perfect.. I have installed my applications, work perfect for two days, but after this... --After wake, display react only in centre area, 1 centimeter from display border no reaction or react on xxx touch. After few seconds (20-30) display react on full range, but with lags... So... I go for support to Samsung official at CZE.
Support tells me, that they don't know about this problem, that I'm 1st who has this problem... And some other bull... about unofficial sell and any other. So I post them IMEI and they let me know, if my distribution is official or not, and we'll see what next. They recomend me to go to service center, where somebody looks on my SM. So I see tomorrow.
ROM - official Android 7 Nougat from start using (not updated from other version)
Deleting apps - no effect
Safe mode - no effect
Factory reset - no effect
Apps to calibrate screen - no effect

Ghost touches

This is a pretty big issue that blue up on the OnePlus forum and Reddit. People are experiencing ghost touches in apps. It's very easy to also experience this by opening cpu-z and letting it sit there for a minute or two not doing anything. It seems not everyone is experiencing this though. I have tested and do experience it. Do you?
Yup. Mine does with cpu-z open. what do we do?

Depends if it's a hardware or software issue. Personally I already submitted a return request with OnePlus.
I just cancelled my order.. hopefully there is a software fix for you guys
This only happens to me on cpu-z and not in any other app. So I guess a future software update is gonna fix it.
Left it for a minute and didn't notice anything. On 9.5.3, bootloader unlocked and patched boot image with root.
I haven't experienced in a few days, it was happening a lot until I disabled pretty much all gestures.
I installed CPU-Z just to check on my International 8GB/256 model and I've got no issue with ghost touches. Not sure what is causing this for you all, but I do hope it is sorted out for you all.
When I turned off NFC the issue went away for me glad I don't use it whatsoever haha

Well that's not a solution disabling a useful feature to not have ghost touch issue.
On screen/off screen gesture are one of my favorite using it, so not a solution to me.
Simple will return the device.
I haven't order yet but i will next couple of days.
There's many reports across oneplus forum.
https://www.androidpolice.com/2019/...ros-are-suffering-phantom-touch-input-issues/
I left CPU-Z running for at least 10 mins.
And all is OK. Maybe it's a rouge program or something to do with the unlock\twrp?
The only way to be sure is to reset to stock and only install CPU-Z

Wow that's seems real bummer.
Why would OP use Novatek display controller since had bad reputation and bad track record.
So the question is how do we know if all that units effected having all of the them Novatek display controller?
Or if there's another supplier for those units that don't have that issue.
Man things are getting much worse if it's hardware related and not software that I thought.

It's extremely annoying it has happened to me a few times even when I was boasting about the new device to some colleagues at work. I thought it was me at first until then I read IRS an actual thing. I won't return it yet but I might if it's not sorted soon. It's extremely irritating.

Looks like ghost touches are related to NFC. Try with NFC turned off.

Can confirm. My Ghost touches seize when NFC is disabled.

I've started yesterday experiencing that ghost touchs and also screen not responsive to touch in some panel sections (mostly the upper right zone). The phone didn't gave me that problem since I bought. I noticed when this happening, pulling the notification bar down to the tile settings makes that zone work again. Same thing happened when that random ghost touchs happens.
Didn't had any problems, don't use NFC, tried turning it on, ghost touches started appearing on cpuz, but not on other apps. As i don't use NFC i probably won't return the phone.
I just tried with CPU-Z and a few seconds after starting the app, the screen turns crazy tapping here and there. Can confirm also disabling NFC solves it.
Turning off nfc or not using gestures or not using cpuz app is just temporary solution.
And there's multiple reports that ghost issues happening other app too.
And we never know if thing get worse over time.
I'm afraid it's a more common issue than we thought but many users simple didn't notice it until now.
Oneplus should clearly take attention on that issue seriously and fix it ASAP.
Shouldn't be happening at all with any kind app or scenario of usage.
