touch problem - G 2014 Q&A, Help & Troubleshooting

I'm facing a problem,
When I swipe up or down on Facebook or Playstore or browser sometime it detects those swiping as touches and it gets very irritating

I get this occasionally. Started happening after I applied a screen protector. Stopped it by being a little bit firmer with my touches.

[Q] Screen Sensitivity

Hey guys.
I've got a pretty annoying problem. The screen of my z1 is too sensitive to the touch. Sometimes when I use the device it starts to open random apps and it's because of the oils of the fingers. When I wipe the screen it's working perfectly fine but if even a little liquid touches the screen it starts acting all weird. I've noticed that this is happening after I removed the Anti Shatter Film. I tried to edit the clearpad.idc which is supposed to decrease the sensitivity levels but I haven't noticed any difference at all. I have read about other people having similar problems like screen not recognizing the touch every now and then. It works perfectly fine for me when on flat surface and everything. The touch input in diagnostics app never fails as long as the screen is clean so I don't think the hardware is faulty(at least not in my case.) I would appreciate any help! Thanks
EDIT: Actually fixed this by editing the clearpad.idc. I set the screen touch filter to 6 and then set the chmod 644 permissions which I didn't do before and this might've caused it to not work before. Been testing for 10 minutes and everything working perfectly. )

Isn't it supposed to be that sensitive so it can work with a pencil as a stylus? At least I think this was the phone Sony said can do that.

Does anyone else have an unresponsive touch screen?

I first noticed this on a running game where you have to hold down either the left or right side of the screen to move in that direction. It would usually register the first press, but not that I had held my finger down so I wasnt moving properly. I thought this was due to the game it's self rather than my phone.
I've just downloaded Naugh where you have to rotate the screen by touching either side of the phone, and again the same issue. It's really unresponsive - It will recognise the tap but not that i've held it, it will stop working. Occasionaly this will also happen when scrolling a page.
I did a quick google search and found that the Z1 had this issue, but havent found a fix.
Has anyone else experienced this? Or if not, any suggestions on figuring out whats wrong?
Edit: I recorded a video of exactly what I mean: https://www.youtube.com/watch?v=UW2gCWpThWc
I don't know if my problem with my screen is related to yours, but i'm experiencing some problems as well.
On the picture i attached in this post is a picture taken of my screen with a black background.
In the middle of the screen there is a slight discolouring, and in this particular spot the touch screen is very unresponsive, i'm especially noticing this when playing candy crush, making it almost impossible to swap the two candies in this particular spot
Both of these sound a bit like my problem was at first, but mine quickly got worse (in hours) and then I found the hairline crack in the screen.
Bottom corner and not in a part of the screen that displays anything - just the 'glass' front at the bottom - but a third of the screen near the middle doesn't respond to touch.
It gradually got worse over a couple of hours until it stopped responding altogether.

Anyone else have touchscreen problems?

The screen on the S8 is weird. Very often when sliding the finger it will touch random locations. Sliding right might cause a slide to the left. Sliding down might cause a single press in a random location. It happens a lot. And I have tested it with completely not touching the edges of the phone so it is literally just the one finger in a constant motion with no lifting at all during the touches. Anyone else have this? It's literally annoying enough to return the phone
I'm experiencing a screen issue too. Not exactly the same as yours, but an issue nonetheless. When installing an app via package installer, tapping "install" in portrait mode is no responsive. It's only when I rotate to landscape mode that the screen responds. Very frustrating.

Automatic touch and bottom navigation not working

I am having this problem since a few month, after the phone fell and got a barely visible crack on left side of screen i assume this problem started
It keeps on touching random places automatically and does not respond to my touches, sometimes locking and unlocking phone fixes the problem.
but the navigation bar are not working at all
I am thinking will installing a custom rom or formatting the phone solve the problem in case it is software issue.

P10 touch screen responsiveness issues

Hey guys my first post here!
I'm having touchscreen issues after the oreo update (android 8). I got the update around 10 days ago.
I'm experiencing the following:
- The most important: Taps not registering sometimes. I used to be able to softly tap anything without any problem, but now my taps are not registering sometimes and i have to double tap.
- Bad scroll detection : the device sometimes recognizes scrolling as a knuckle gesture (crop screenshot) or scroll responsiveness is laggy.
- Tap registering as a knuckle tap. This happened only once. I tapped two times with my finger as the first one didn't register and it took a screenshot.
My use of the phone didn't change since the update and I'm kinda concerned. Is this a software problem? Anyone else experienced something similar?
I have the same issue! Many times knuckle gestures turns on not recognize correctly the touch.
Reboot phone in recovery mode and select format cache.
Restart and try touchscreen again.
Same issues with touch screen response after Oreo update.
Format cache does not solve the problem.
Sometimes is not registering finger. Sometimes register as double tap.
This is happening with my phone as well. It also registers phantom input, like occasionally things on far away from my fingers. The YouTube app has been especially sluggish when scrolling or swiping, to the point where it confuses swipes with taps and opens random stuff while lagging, or just crashes. The gboard is also becoming increasingly unpredictable and sometimes it feels like everything is being registered a litte skewed.
I checked the memory in case I got one of the bad ones, but it seems ok. It must be either the screen or a software thing then?
Same issues on day one from last year nougat rom
Any updates on this issue?
I am on 369 and is very annoying.
Any solution?
Downgraded to Nougat with HiSuite and problems with touchscreen gone.
I have problems only on Oreo.
Friend not having single issue on Oreo.
Don't understand.
