I use Gboard and the issue is not so bad on my device.. maybe are you using a screen protector? Im reading now in internet sometimes ghost touch problem it depend from a screen protector...
Personally I think is a software problem.. maybe Samsung is collecting the keyboard activity? So maybe there is generating some software conflict??

screen responsiveness problem

Every couple of days I have a problem with the screen becoming VERY unresponsive. It seems to affect the whole screen and requires touching characters on the keyboard, web buttons, app icons, etc. multiple times before the touch is registered. The problem persists until I reboot the device.
I haven't rooted yet or otherwise modded it at all, but maybe I have a poorly optimized app running? Haven't tried to capture a logcat yet either (and frankly wouldn't know what I was looking at).
Has anyone else experienced something like this?
Thanks!

Looks like mine is suffering something similar to the problems discussed in this thread:
http://forum.xda-developers.com/showthread.php?t=1779652
I also have this issue. Was able to reproduce with multi touch tester apps. When I cross axis the touch points freak out. I think it's a grounding issue. If I touch the headphone jack or have headphones in the issue goes away. Called in a RMA request yesterday. Hope this issue isn't present in the next device.

Do you also face touch problem in your K3 note

I'm facing a very annoying problem in my k3 note, that some areas of screen randomly stop responding. In my phone its mostly limited to bottom right part of my screen where backspace on keyboard is located. Rest of phone is responsive except this region. Restarting the phone fixes it temporarily.
But strange part is it doesn't happen on all ROMs, I first noticed it in some AOSP MM ROM, then i think it was Andronium VUI ROM (based on dev 1628) and now on s433 rom which leads to believe its some software thing not hardware thing.
Are there others also which face similar issue ? Any possible solution except switching to different rom ?

Yes, I have this problem with the screen also. I've heard from others with similar issues on other forums. It seems it is a hardware fault or possibly an issue with the way software interacts with the screen controller. In my case the screen is periodically unresponsive around the letter E or R on the keyboard and I have to tap the area with greater pressure. Sometimes it gets very buggy and very frustrating.
There is another possibly related problem when scrolling a web page or dragging - larger areas of the screen become unresponsive. Turning the screen off and then back on fixes the problem for the next 2 or 3 minutes. This issue has also been fixed for me with the kernel from daniel_hk here http://forum.xda-developers.com/k3-...rnel-dc-mtk-m1-kernel-vibeuiv3-51631-t3483573 - the only proviso is you apply it to Vibeui 1631. So while the scrolling issue seems to be fixed, the unresponsive areas around letters E and R on the keyboard remain.
I've noted the problems above would temporarily go away after flashing a new ROM however they eventually return. I've considered buying a new screen but not really sure if its a hardware or software issue - possibly both!

hmmm it's interesting that different people have different areas of unresponsive screen. It seems more like software issue to me, as I started noticing this issue more on newer dev roms only. Today, I've reverted to dev ui 3.1 1622st as I remembered it didn't have it. Will report in couple of days of how it goes, so far haven't noticed it.
I have been facing touch problems for quite some time on the ROW version of the ROM s433. The touch starts acting weirdly, i.e random things start getting touched automatically and this happens mostly in the lower half of the screen. I turned on the show pointer location option from developer settings and it shows the pointer stuck at one point on the screen showing erratic behaviour. Turning the screen off and then back on solves the problem but very temporarily. Restarting solves for a longer time but the problem pops back up.

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.

Multitouch with +5 fingers

****UPDATE: *****
This is what happens https://imgflip.com/gif/1xvxm0
What can be the cause of this? Does this happen to any of you as well? Should i open the casing and see if there is anything touching the metal casing that should not ?
****EO UPDATE ****
I have been testing with both
Settings -> Developer Options - > Show Pointers (and looking at the top left that says x/x points)
or
Using a multitouch test app like so https://play.google.com/store/apps/details?id=com.the511plus.MultiTouchTester
The latter is nice because it has big handlers and you can clearly see the point/touch flickering like loosing and creating point (hence creating a new point ID)
From what i can say in Marshmallow it worked way better, on the last 2 Nougat updates i saw that at the 7th point it started to do the flickering and with this one it starts at the 5th point.
With 3 fingers screenshot disabled (and all the gestures for that matter) as i know it would create a conflict.
Just tested in a Motorola with Marshmallow and it created the 10 points flawlessly.
I wonder if any of you noticed the same or is something off with my touchscreen?
Might it be a Nougat thing ?
Any known solutions?
I searched around and nothing Nougat related seem to pop up
Just tested with both OP2 and a Moto G5 and they both work great, actually it even worked great on my Samsung Galaxy i9000
I have noticed that for the last 2 updates or so multitouch capability has been decreasing.
When are you ever going to use ten fingers to multitask? If it wasn't for the screenshot gesture, we wouldn't even be using three.

That is irrelevant for what i am trying to figure out, what i want to know is if it is a HW problem by default or just my HW is faulty or even if it is a Nougat problem.
It works flawlessly on other less capable phones
Either software or hardware fault I would say. I just tried it out without any flickering with 10 fingers on my 3t running latest unofficial LineageOS 15/Oreo ROM.

Thank you, from what i get so far is a Nougat thing, all the users that have Oreo seems to work fine
Conductive electricity ?
Ok some pretty strange updates...
I accidentally tested it on a metal table and it worked perfectly, which lead me to think that it might be due to conductive energy or something.
So i tried the test on a wooden table and it does flicker and loose touches, so i pressed with a finger on a metal part of the OP3T casing and the points are registered properly.
I had made a video so people don't think i am crazy here is the result https://imgflip.com/gif/1xvxm0 at this point i can say that is directly related.
What can be the cause of this? Does this happen to any of you as well? Should i open the casing and see if there is anything touching the metal casing that should not ?
anyone ?
This is a non issue honestly. If it doesn't change how your phone functions in day to day practical use, you probably shouldn't bother with something like that. The touch display functionally is fantastic especially the screen colors and with the recently fixed touch latency it does happen to be one of the best screens on the market despite its lower resolution. Factually you won't use more than a three touch input so. IMHO

It is definitely a problem did you watched the video ? because it seems like a real hard problem to me, use cases for you might be different from others. My old samsung galaxy i9000 as well as my OP2 did not had that problem
It may be a problem for one and may not be a problem in another's eyes.
To address your issue, have you tried switching ROM's? I don't think it could be a Nougat problem, but you might as well try Oreo or even MM.
This may sound funny, but have you tried with another person's fingers?

I had the feeling that it might be from the updates (still using official OP updates) but right now i think it might be hardware. Yes i tried with other fingers, thinking about opening the phone to see if there is something touching the metal case inside.

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
Seems OnePlus using Novatek panels https://github.com/OnePlusOSS/andro...input/touchscreen/oneplus_touchscreen/Novatek
Poco F1 had same problems with Novatec and only way fix it was replacing whole panels, they tried to fix over updates but witout luck

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.
