[Q] Nexus 4 Ghost touches

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.

Ghost / Phantom Touch

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.

Scrolling problems

Hi everyone,
There is a problem with my new OP5 which bothers me a lot. When you scroll long pages really fast or with short swipes sometimes it:
1) stops for no reason
2) goes the opposite direction
3) scrolls really slow even if you swiped fast
I tested two OP5 with latest updates, and they both have same issue.
Did anyone else notice that problem? Is there any possible way to fix that?

Do you have a screen protector on it? I've had a few phones where the screen was glitchy like that w/ protectors on it, my N6P being one of them.

touch registration issues

I thought it might be a sensitivity issue because I'm coming from a N6 where I barely touch the screen and it registers. I did some testing and turned on show visual feedback for taps in developer options and I started tapping on the screen in random places every 2 seconds and on average every 5th tap it didn't register and sometimes it's the second and I had issues sometimes where 3-4 taps in a row in different places wouldn't register. For me it's not isolated to certain parts of the screen like many people have found, for example only on edges.
My sample size isn't very much but I've figured out that the majority (or only UI elements because I haven't tested enough) tapping on or around UI elements such as toggle settings in the developer options, any app (swiping/scrolling in apps too) that this issue occurs. When I moved an app icon to create a new screen and started testing I never had any registration issues(visual feedback for taps and long pressing to bring up the wallpapers/widgets/home settings intermittently between taps)
So is this a hardware issue, software UI or maybe a mix of both? I don't know enough about touch screens and android. I don't want to RMA if it's software but I do if it's a hardware issue. Does anyone have any insight on this?
So I did a factory reset and it's working perfectly now. I don't know what was causing it but it's good to know it wasn't hardware

I have the same issue, fingers crossed the upcoming update will fix this.. Mostly its a software issue (or hoping so), but I've seen few complaining about this..

I have the same issue. Its most likely a software issue that can be addressed through an update.

Mine seems to come and go. Sometimes it's fine; sometimes I'm having the same issues you're describing.
I was thinking last night it seemed like every once in a while a double tap is required, after idling for a few seconds. This to me sounds like a driver issue that could be fixed.
Today however I'm thinking it might have something to do with cold dry fingers, as I was having it outside but it's totally fine now indoors.
Can't really put my finger on it yet. Gonna give it a few more days before I think about an RMA.

Any of you guys using SwiftKey beta?
edit: are you on 8.0 or the 8.1 preview?

Just got my xl today and I have this issue. It's just randomly around the screen and not in any specific area.

I believe my phone is not recognizing vertical sliding if it is diagonal, versus the same diagonal slide on my 6p is recognized. Not sure why this is happening but I believe it is intentionally being done because if I touch same spot and closer to vertical up and down, it recognizes it.

I am using swiftkey Beta on 8.0 and all functioning great

I don't know if this is related but I've been using accubattery and after I did a factory reset I didn't install it at first and everything was working great then I installed it and after awhile I noticed the issue come up again. I uninstalled it about an hour ago and did testing and the issue is gone.
I'm on 8.0
Issues came back even with accubattery uninstalled

I have the same problem. When trying to scroll a web page in Chrome, I have to touch twice to get the touch to register. Also having trouble with the long presses.
I'm on 8.0
I have Swiftkey (not beta)
I do not have Accubattery

I'm having major issues with this all of the sudden today. Something isn't right. Ugh - one issue after another.

I made a video of my issues:

Sometimes, when trying to scroll a web page in Chrome beta, I have to touch twice to get the touch to register. Saw this on 8.0 and now on 8.1.

That's horrible. I opened my gboard in chrome and it doesn't do that for me but it will do that swiping/scrolling, randomly typing and with GUI elements sometimes. Multiple times in a row to where i have to just stop tapping and wait a second or two and tap again.
I'm going to try using the 8.1 dev preview to see what happens

I'm having this issue too

I get the same thing while typing, i'll think i tapped something (because I know i did) but it won't register. Extremely annoying and all 3 phones I've gone through had the same issue, getting tired of RMAing

I mainly get this problem with gboard and the home button. It will double click a lot when I only touch once

I'm also seeing this randomly as well! This is my biggest bug right now...

I installed the 8.1 dev preview and right off the bat it's working perfectly but let's see what happens in the next few hours. I don't understand why it's fine then all of a sudden not. It's completely ridiculous
Make sure you guys are enabling "show taps" under input in the developer options because when you tap and the visual feedback doesn't show then it's not registering. Enabling "pointer location" helps make it more obvious also

Screen Freezes and Problems Typing Text

Noticed quite recently that the phone keeps freezing on apps only way is to close the app down clear from recents and try again. Or lock the phone and unlock it. Also having problems now when typing something out the keyboard accepts my typing but the text does not show up on screen. So I could be writing something out and half way through the text stops showing up. Starting to get frustrated with this phone now. Especially with news of another new phone coming out and this 1 does seem to actually have so many faults.

Constant crashes now on certain apps. Mainly Chrome.
I know alot of people find Chrome buggy but on mostly every other phone I have never had crashes like this.

Chrome seems to have issues with 120 refresh rate from what I've read. Happens on mine and I've read about it happening in the s20. It's the only thing they slows down at all on my phone

I also see this in Chrome & Chrome Beta!

Interesting. I use Gboard and haven't had a single freeze

This happens to me all the time with Chrome. Incredibly annoying. In fact, it happened as I was typing this!!

I've had these issues but they disappeared after I took the Android 11 DP for a test drive. After I rolled back I haven't seen any of these glitches at all.

I get this sometimes and as silly as it sounds I'm actually touching the phones screen further up on the display.
Cleaning the phones screen helps as well.
Think QHD can cause this too.
Haven't had this issue persistently as you've mentioned though.

I never had a single slow down with chrome on my OP7 pro. All I know is I've read in many places 120hz send to be the problem with chrome. One way or the other, it's a chrome problem, not a phone problem

It's Chrome. I thought my 8 Pro was broken (I dropped it, then was having problems like you describe). Went back to my Nova5T, and Chrome hangs up in exactly the same way. Nothing to do with the OnePlus at all.
