I've had this phone for a while now and I've had one issue that is persistent and very annoying.
I get a ghost or phantom touch when scrolling. Basically, I'll be scrolling through a webpage or Facebook or anything really and as soon as I put my finger to the screen and swipe up the phone will register this as a touch. This causes all sorts of issues like posts opening that I did not intend on opening or misdials.
Does anyone else have this issue? I'm on stock (rooted) with the september security patch. I did a factory reset today hoping that that would fix the issue as I was on TruPure before the stock rom I'm on now. I still have the issue, the factory reset did not fix the issue.
If anyone has any ideas or a solution, I'm all ears.
Thanks.
Me too, maybe. Upper left quadrant of screen becomes crazy. Touches produce random responses if not wild responses. Think software as reboot fixes. Sometimes walking away fixes it. Happens after phone has been actively in use awhile. Maybe memory or buffers are full.
I am clueless.

I'm experiencing the same exact thing, and yes it does seem to be focused in the upper left area as well. I replaced my screen a few months ago and thought it was the cheap screen failing. Are you on original or replacement screens?
New phone. Unlocked, TWRPed, systemless Root, stock ROM.

Hi all,
would like to ask for advice. I've been on my N4 for close to a year, but recently I've been having some touchscreen issues. on occasion, my nav bar alone does not respond to touch and would require a reboot. On other occasions, the whole screen does not respond and requires also a reboot. Most of the time, a single reboot would solve the issue, but sometimes it requires 2 or 3. Also, there is a particular area on the screen where the touchscreen sensitivity is essentially non-existent (i.e. any button at that area cannot be activated). has anyone ever encountered a similar issue and whats your fix? I'm rooted on PSX and hellscore.
thanks!
I had have had problems with the sensitivity. I flashed another rom and it was fixed. So it was a rom related issue.

Hi,
I've just updated to 4.4.2 and my screen is acting crazy, when I touch in one point the screen reacts in a bigger area somewhere else. For example it presses all three bottom buttons at the same time, while i aim totally different area ;/
Any one has/had the same issue ?
While I don't have the exact same issue as you, I do have some random ghost touches and gestures being"interrupted" so to speak. It's pretty annoying cleaning the screen up a bit and lock/unlock it kind of goes away temporarily only to return. I had this issue with stock 4.2.2 as well though. For whatever reason I don't exhibit the same issues on aosp based Roms. I know others have had issues with touch as well with varying degrees. Perhaps the touch screen driver in the stock kernels just don't like me. Lol. Sorry nothing that really helps but take it fwiw. Yours sounds pretty extreme. Did you have any issues with it prior to the update?

So I bought a used N4 sold as is because the seller said he had some issues with the ROM and the touch sensitivity and all it needed was a stock ROM flash. I took up the challenge and flashed stock 4.4.4.
While I'm at the home screen everything's fine, as soon as opened the app drawer there were random touches all over the bottom half of the screen. Some were shown in the center and many at the bottom left corner but most were just random. I mean like 7-8 touches per second. The same happened whenever I went into play store, Opera or Chrome. Didn't test it further since I decided to try another rom.
Flashed Purity ROM and at first glance it worked flawlessly. Not random touches in home screen, app drawer or settings. Then I flash Gapps and the same thing happens with Play and Opera.
The funny thing is that the problem persists but at different circumstances. Can't pinpoint the exact cause. Should I get a new screen and try? Or maybe something else is at fault there?
I've been having the exact same problem as you. It started after I replaced the screen and the usb flex.
Ghost touches 1-2 each second only on some apps (none on homescreen or settings). I noticed that it happen in 4.4.4 app drawer but not in the 4.2.2 app drawer. I got almost no ghost touches on 4.2.2 messaging app also. It happens in almost any app, like play store, dropbox,chrome....
I thought it was the battery so I replaced it, but it did not fix it.
I have been trying to troubleshoot the problem but I ran out of theories. I wish the best luck to find the solution, as I almost gave up on it. If you happen to solve it tell me.
I think i found out what's causing this issue.
My theory was that apps with a lot of white would trigger the ghost touches. So I tested with flashlight screen apps that only show white on the screen. As expected the ghost touches only started to appear when i turned the flashlight on.
Therefore my theory was correct.
In my case I will contact the seller that sold me the screen to see if I can get a replacement.
I've had the intermittent touch screen issue, just above the capacitive buttons and also the ghost touches.
Started about 2+ weeks ago.
I reverted back to the stock "HOME" launcher instead of the Google Now launcher and that seemed to have fixed the issue.
I will have to keep an eye out to see if it lasts.

Hi everyone. this is my first post. i may make some grammar mistakes, because english is not my native language.
I found a solution for the ghost touch issue on my nexus 4, so maybe it can help who is having the same problem.
1- Download and instal the NOMone Resolution Changer on Play store
(this is my first post here, so i cant paste de link here, but you will not have trouble to find it)
2- when asked, Allow superuser
3- open the app and change the height resolution to 1250. (it worked for me, but make some tests to see if you need to disable a bigger part of the screen to avoid de problem)
This is not the best way to keep using your phone, because you may lost a part of the usable screen, but worked for me.
Thanks!
I workaround this issue avoid using undervoling in the kernel, and avoid lower temperatures in phone, yes as you read ... this issue give my crazy when my phone was to hot and I tried to cold my phone using one ice cube in screen and back, the temperature of the phone down but ghost touches appears again, so played some videos to warm the phone again and dissapear again.
Don't ask me about how it works, or relation with screen, digitizer or battery, I don't understand but help me to workaround the issue.
Hi all,
I just got an S7 as an insurance replacement, and the touchscreen has been very inconsistent when scrolling through web pages, apps (Facebook, Twitter, Tapatalk), and even the launcher.
Scrolling through these sites, the page jumps ever so slightly, but it's enough to give me a headache after 20 minutes. Typing works just fine, though.
Before I call to get another replacement, is this a known problem with the S7s? Or did I just get a bad refurb?
- I'm coming from a Nexus 6
- I searched the forum
- Running stock Nougat, not rooted or modified
- I performed a factory reset after Nougat update, problem still exists
Thanks!

Touch sensitivity of top part of screen is very low, this leads missed "notification pull down" if done quickly.
The below video shows the issue. One can see that the pointer trace does not happen at the top part of the screen, when done quickly. But if swiped slowly, the trace happens from the top, this means, that during quick swipes, the top portion touchscreen is unresponsive, that leads to missed notification pull down.

Any one with similar issue?
I have already submitted this as issue using mi feedback app.
Probably just your phone. Mine's doing well.
Are swiping down from off the screen mate?

This was an issue on my previous Redmi Note 2.
Whit A1 I'm not experiencing this problem.

Hey man, i also got that problem when I was using Pixel Launcher. At first it wasn't an issue, everything was fine, but around 2 weeks after using it, i got the same problem as you too, in fact it was yesterday. Today I'm still seeing the issue but not as bad as with the Pixel Launcher, i think something else is triggering this issue. So, maybe you can try to use the stock launcher first? (I'm also still figuring out what the problem is)
Best regards
Did you test it with stock Launcher too?

I watched your video. I am using Lawnchair as my daily driver so I switched to stock launcher to test it, because in Lawnchair this couldn't be a problem (you could pull down notification shadow from anywhere on the screen). But even with stock launcher I couldn't confirm this and I tried it really hard with hyper sonic fast pull downs.
BTW Lawnchair has its own issues, I opened one for similar problem: Unresponsive top row.
Hello ashjas
I purchased brand new Xiaomi Mi A1 and I am having exactly the same issue as on your video. Did you get it fixed?
