...as the title of the thread says, sometimes - in irregular intervals - my tochscreen recognises false touches. I can see this through the developer mode option to visiualize screen touches.
The false touches are always in a horizontal row in the upper area of the screen. It is not a hyper sensitive cause, because I don't even strike the screen anywhere.
When the failure appears it always looks like the device has it's own living, because I do nothing.
Do you think that this is a soft- or a hardware reason?
I'm very thankfull for help.
You should have a software update waiting on your phone to be installed that fixes this problem.

I tested out the HD2 outside in below freezing temps, and it really had a tough time registering my finger presses. It took about 5 minutes, before it could register properly... Anyone experience these issues?
Yes, and the wind keeps pressing things which makes it almost useless. I'm hoping some of the hints here on how to make it less sensitive will help but I haven't tried it yet.
I've noticed the "ghost" pressing (the screen registered a LOT of presses when my fingers were nowhere near the screen) of the screen too. I also contacted HTC support on the issue, and they said it was not a known problem.
So, again, I'd suggest that if you're experiencing issues with the screen in cold temperatures (finger touches not registering, "ghost pressing" etc.), let HTC know about it!
i got that kind of ghost typing too. pretty funny to watch but annoying when you see its deleting mails, answering sms or calls people ... will contact htc as well to let them know.
Confirmed here too. Though I thought it was caused by constant rain/snow here in Moscow, which fell directly on the screen when the ghost tapping occured.
Yeah I get the ghost tapping but only after i've been in a call and hang up, it then starts doing all sorts of things by itself normally ending up with dialling someone!! :/
I dunno about the ghost-typing but isn't it a common fact that capacitive screens don't work well with low temperatures?
That's a capacitive touch-panel "Feature" . HTC can't do anything about it (besides lowering the screen sensitivity).
edit: Umiss beat me to it lol
you can lower the screen sensitivity either by installing the new 1.48 rom or using the cab from the hints and tweaks thread in opening couple of posts. Should help.
Hi All,
I have recently bought S4 and I'm having a small issue with it.
first of all, I turned off the "More Sensitive" feature in the setting, and "vibration on touch" is on.
However, I occasionally feel that touch is pressed before my finger actually touches the screen (the phone vibrates and types before I touch the screen when my finger is about 2~3mm apart from the screen), and it seems it's not consistent about it (some times it touches with 2~3mm gap and sometimes it doesn't).
I have even tried with the "display touch" from the developer mode and verified that it indeed touches with 2~3 gap...
The problem is...the ATT guy looked at me as if I'm overly sensitive about this...(the typical look of 'man this is just a phone')
Is anyone having this issue?

I have rarely noticed this myself, but usually only a 1mm-2mm gap for me, and maybe once every couple days. Really infrequent. On an older phone of mine, the cheaply-made car charger I was using caused my touchscreen to flip out and become super-sensitive. Might have been a static-to-ground issue or something weird.
Does it happen when you have it plugged in only, or does it happen while disconnected?
Also, speaking on static electricity, is it dry in your area? Do you have problems shocking things?
*shrug* only some suggestions. Could be a miscalibrated or otherwise defective touchscreen...
Mine also does this, whether plugged in or not it does it.
Nor do I have a problem with static in my house.
My best guess would be the air view sensor is falsly detecting the small distance away as an actual touch.

Hello
I have 2 months old LG Nexus 4 and I have a problem with touch screen. These is a field in a buttom of the screen whitch is not reacting on touch. I ca touch it 100 times and nofthing happens it is not respondint to anything even harder touches.
so the field is here
shrani.najdi.si/?2k/2D/4dhib9sI/screenshot2012-11-04-14-.jpg
under these field and above is screen working normaly. now i want to know if is these maybe a softwere bug or is these a hardwer one and i should take the phone on the serverice, btw the phone never fall or anything else.
Thank you for advices.
Try going to developer options, enabling here "Pointer Location" and then swype across the screen a few times so there will be a long blue line (it's important to move your finger on the screen near that faulty place). If your finger suddenly stops drawing that blue line then it's definitely a hardware problem.
Now I know this problem has been asked before but after some extensive searches I can see there are no clean fixes for this.
My Nexus 4 (Android 5.0.2 LiquidSmooth ROM) has started showing ghost touches at the bottom part of the screen. I know there are a lot of explanations available such as digitizer not working, battery being too old etc. But I'm not interested in these hardware issues/fixes.
I have isolated the area of effect as the bottom ~160 pixel height of the device. I then proceeded to use the ADB shell command
wm overscan 0,0,0,160
which removed that portion from the UI. This fixed the effects these phantom touches have on the apps or UI. But a problem still remains that these ghost touches happen in too many numbers and this leaves other usable areas of the screen insensitive to touch. I am guessing this is due to the multi touch limit being reached in that bottom unused part itself. Multi touch testing apps dont pick up touches on the top part of the screen
So my question is, is it possible to remove a part of the screen from the System itself? Ideally a thick black bar of unused area, leaving me with a shorter yet fully working screen? Or atleast is it possible to turn off touch response in that lower part of the screen so that it doesnt max out the multi touch limit?
My Nexus 4's is same too
I think, that ghost touch will work from Screen Digitizer. My Nexus 4's screen digitizer was non-LG's digitizer, it was fake. I need to change that digitizer
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.
I have a Moto G4 that has had the touch screen become very erratic lately. This issue appeared shortly after a factory reset. The phone is stock, recently OTA updated to NPJ25.93-14.7. It frequently freezes and won't respond to touches of apps or the home/back/recent buttons, and won't side scroll to the next screens properly. Sometimes random apps launch on their own without any touch, and if you try to quit them with the back button they keep relaunching. The problem is intermittent.
I activated "Show Taps" in Developer Options and when the problem is happening there is a tap dot near the lower right side of the screen. It bounces up and down a little bit and vibrates sometimes. When this dot is visible tapping on anything else like app icons or buttons usually has no effect, however the taps are shown on the screen. If I hit the power button to make the screen go black it will sometimes recover when I reopen the display, other times it takes a reboot.
Wondering if it's a hardware issue, a guy at a Verizon store who seemed to know more than most said it was a faulty digitzer--it's seeing touches where there are none. I've replaced displays successfully before, would just like to have a confidence level that the digitzer is really bad before doing that, as opposed to a software or other hardware issue. Any ideas about problems that might cause this problem, like other hardware or a corrupted OTA? Seems very hardware-ish to me, but I'm no expert.
I have Drive links to a couple of short videos on the symptoms, can send links. Much appreciate any insights.
Mine has that issue as well. It will spam the 9 key on the unlock screen or anything in that spot if an app is open or what is on that spot at the home screen. I have to double unlock the phone to fix it. I guess turning the screen on and back off resets it for that session. But it's mostly every time the screen goes dark and comes back up I have to turn the screen off and back on to use the phone.
I had a similar problem and was able to send it in under warranty and get a replacement phone
G4 Digitizer or ghost touch
Apparently this is called Ghost Touch issue, and affects many phones. One solution tried is to disable Battery Optimization for System UI and Google Now Launcher in Settings>Battery>Battery Optimization. That seemed to cure it for a week or so, but the problem returned today. I can sometimes recover form it by hitting the power button to blank the screen and then reopen. Other times it requires a reboot. I see all kinds of alleged solutions out there from dimming the brightness to removing tempered glass protector to using a slow charger, but those don't seem like real fixes but workarounds (if they even work at all). Any other ideas?
