So, my current XT720 started having episodes of that dreaded "ghost touches" insanity two weeks ago with escalating frequency. Last week it started to happen roughly every two hours. I found that wiping the screen off on my shirt would help for a few minutes, but I just assumed placebo effect (somewhere I had read that the ghost touch problem results from ground wires coming loose--so I was contemplating disassembling and reassembling--except I can never get that stupid "8.0 xenon" sticker to come off cleanly in the past so I was holding off). On a whim I googled a bit and found on a droid forum that someone was claiming that cleaning the screen with an electronic wipe solution solved the problem but that success can depend on which cleaning solution was used. I was skeptical, but I had a pack of Windex electronics wipes so I figured "try it"... the ghost touches disappeared immediately and have not returned (it's been 5 days). So, clearly some sort of residue on the screen was responsible.
So that got me thinking. I'm currently using an XT720 I got used that came without a screen protector (My wife is using my original one that has a zagg invisible shield since day one and has never had a ghost touch problem). When I got my current one, I debated whether or not to install a screen protector and decided to give it a shot without (which is really nice by the way--the screen does not scratch even when you forget and drop your keys in the same pocket--but it does develop get a weird patina which is what the cleaning seems to have removed--the zagg has a nice feel to it, but it's got a strange uneven surface that takes some getting used to, so the shield-free experience was a nice change for the fingers--my only objections were that sometimes it seemed way to sensitive to touch and that the bevel edges around the screen feel too recessed so the design seems to anticipate that a screen protector is installed).
So, my question is: I can hand-wave an explanation that a conductive/capacitive membrane develops on the surface of the screen and interferes with normal operation of the digitizer. And that perhaps a screen protector counteracts this either by keeping whatever this conductive/capacitive residue is slightly further from the digitizer or possibly by preventing generation of this residue due to different surface properties. Have people had the ghost touch problem with screen protectors?
I can t really help you i never try any screen protection
But i had ghost touches but not at all like yours it happened 5times max(in 2years of heavy use) i think and always when it was raining when my screen get a little wet... and it stop maybe 5min after drying the screen
Never got it with out rain...
Same for me... the phone start to open apps alone jaja xD

I've had the ghost touch problem twice now, both with screen protectors. The first time was with the screen protector that came with my Otterbox and the second was with the protective film that comes with the phone new (it worked fine to my surprise). Each time, it happened about 6 months after receiving the phone. However, I've not tried the electronic wipe solution nor any physical disassemble/reassemble operations.
BTW...my previous thread about this: http://forum.xda-developers.com/showthread.php?t=1102074
Hm, seems like what's actually happened is that the left-most strip of the screen doesn't respond to touch at all anymore. I just found it's difficult to type "q" and "1" So, probably the ghost touching was while that element was dying. It's still mostly usable (I can get the q and 1 by slowly moving my finger from the edge). If it gets worse I'll have to think about repair, I guess. I see the glass is available from ebay and I've also amassed a few for-parts XT720s so I've been looking into what's involved in replacing the digitizer but I can't figure out how to remove the front glass from the chrome frame...

Hello guys,
I had these "ghost touches" until two weeks ago. Then, I installed a screen protector and had no problems at all later. I am not an expert of touch technology, but I assumed that putting something between the dirty and the screen would help, and I can say I was right so far
Ah, just one note: just before applying the screen protector, be sure to clean perfectly the screen, otherwise it will not counteract the problem (use for example an electrostatic "cleaner" and a properly clean cloth).
Hope this helps!

Hello there, XDA.
This thread is more for an ensurance for me that I've done nothing wrong when using my phone - and it might show up that some other people have the same problem as I do.
Now, to the thingie. Bought a HTC Diamond about 3 months ago - working just fine. Although about 3-4 weeks ago I realized that when I tilt my screen, I can see some crazy stuff going on... There is two pictures attached and linked to further down.
Anyone else has this problem? Would be lovely to hear what you've done. I sent an e-mail to HTC and the manu... manufactourer-/or~ (spelling :b).

That just looks like moisture between the screen protector and the screen itself.
Odd that it's in a perfect rectangle. I've seen this before on a mates LG Viewty (Horrible phone!), but he never followed it up so I don't know what the cause was. It did have a touch screen, but no protector. Perhaps its moisture actually in the screen or a manufacturing fault?
Good luck.
Oh my - I had rectangle on the screen today when I removed the protective front later (brand new phone).
Though It's no longer showing I'm scared its going to become more apparent and eventually become like this.
What is going on with QA and HTC?
There was another exact case like this that I saw this week. Can't really remmeber but do a search and you will find it.
I have the same thing on my Touch Pro, and another user has had the same problem on his (her?) Diamond:
http://forum.xda-developers.com/showthread.php?t=428262
Unfortunately it isn't moisture below the screen protector, but that the touch resistive layer was subject to heavy pressure (eg: being squeezed in the pocket). It shouldn't affect anything in the short term, but in the long run the touch screen might become erratic or imprecise, so you should keep an eye on it.
The store I bought my TPro from doesn't accept returns/exchanges, and so far HTC hasn't replied to my support ticket. Unfortunately I think some of us are going to be left out in the cold. Personally I'm tempted to buy a replacement touch layer and replace it myself, but of course that would void the warranty (even though it doesn't seem to be doing me any good).
If this becomes widespread, there could be a chance for a class action lawsuit (hopefully HTC will wise up and help us out before it comes to that).
Ouch >.<, feeling sad (but somewhat a bit of relief) that some others has the same problem.
Yes, the rectangular shape is very, very odd - since that makes me think that just pressure can create this mess. It feels more like a manufacturing fault.. But, as for fhsieh, HTC hasn't respond to my support ticket.
Wondering if I should call them to get a direct answer.. Hm.
I've suffered this
But in a Touch Cruise I own before. I thought, as said, that this regular shape can only came from a pressure problem.
Loosing my warranty (due to the long time to be repaired here in Spain), I opened it, confirming that was not a problem with moisture (at least in my case). Also I saw the resistive layer poorly sticked to the body, with zones unglued, causing the layer to raise, specially in the bottom edges. This bothered me a lot, because I ended with lot of dirt between the layer and the screen itself, unable to clean.
Maybe that was the problem. If the layer is not correctly assembled it gets an irregular surface (as lightly squeeshed) , yielding this. But, functionally speaking, the screen was performing well, as it should be.
Hope this helps.
It's only humidity... it happens also in my diamond... try to dry it under the sun..(not so good for lcd but it works for me)..

Yes, it's due to the prefect pressure of the screen, exactly in the center..if you try to press a corner for example near to Start button (with screen off) you should see the spot follow your finger's pressure. So there is a small drop between LCD and screen..(for me)
I had same problem in polaris. Send it for warranty as this is manufacturing fault. Why keep ****??? its htc s fault!?!
Well I thought i was the only one who had this problem till I came across this thread.... it's quite weird it's in a perfect rectangular shape anyone tried removing the protective screen and checkin whether it is the display... but one thing you hve to notice once the display is on we can't see tht on the screen only against a black background can you notice it....
It is the problem of screen protector. You may not see this watermark after you take off the screen protector. Try other good screen protector like Brando, Martin Fields ....

I tried removing the screen protector and the rectangular shape is still there then I put it in front of an A/C cooler unit and it went away!!!! then after awhile it returned back and the place I live is very hot and humid so I guess it's weather which plays a role....
My first 2 Nook Colors experienced ghosts touching the screen while doing nothing. My 3rd had a flake of dust(metal?) under the glass when I took it out of the box. 4th time is the charm? Just got home and I'm seriously not sure if I can handle a 5th time back to BN to replace this thing.
Anyone else with ghosts tapping on the screen?
Are you plugged in? The nook has a bit of a grounding issue and it causes ghost taps while plugged in.
It would do it either way. I don't really use it while plugged in though. Got it to store manuals for equipment I work on(lab coolers, freezers, incubators, hvac, etc)
So basically its used onsite or while I'm sitting in my work van.
One more thing... might be related. I had it usually in the case(not always) and the case I had was the Sullivan Easel. Which, like most, has the plastic clip in retainer thingy majjig.
http://gifts.barnesandnoble.com/Sullivan-Easel-Cover/e/9781616837181/?cds2Pid=3617
I swear that plastic retainer part on the left side is what would pop up the bezel and then you could see light come through. And just maybe, maybe, that was also causing the ghost touches. I don't really know....
So I returned the case and just picked up a black silicone case and screen protector.

The guy at the B&N store said you can get ghosting if you crank the brightness up.
i was getting a ton of phantom taps when i first got my NC, to the point where it was almost unusable. I would wipe the screen of any moisture or prints and it would go away for about 5 minutes until fingerprints and moisture from my hands started to make the screen freak out again.
I put a screen protector on about a week ago, and it's like a whole new device. The screen still isn't very sensitive around the edges, buttons often dont work on the edge of the screen (especially at the top) but I haven't had a phantom tap yet. Seriously, try putting on a screen protector - it turned my NC from useless to awesome for like 5 bucks.
Update: Seems to be working great so far with the screen protector and silicone case.
BTW screen brightness was usually at ~50%.

The cause is normally from your fingerprints that's left on the screen since the screen is so sensitive. Does the screen protector takes care of the problem real good? And is it easy to install?

I use a screen protector also. Without one, i get phantom taps all the time.
Screen protector was bought from BN and was pricey. Came with 2. Can't remember who suggested it but, turn shower on in bathroom and let it run for 10 minutes with door closed. The moisture in the air will 'drop out' all the lint/dust. Shut off shower for 5 minutes and then apply protector.
This is what I do and it works great for all my devices.
Its been 24 hours with the screen protector and silicone case. No ghosts yet.

So I bought an mEdge cover from Walmart and I also installed a clearcoat screen protector on the tablet just after receiving my tablet on Dec12. A week ago I started noticing a faint purple "shadowy, airbrushed" line in the middle of my screen when there's a bright white background on. At first I thought it had to do with the screen protector, but no matter how much I'd wipe the screen free of smudges I would still notice the airbrushed line.
I then suspected that it had to be the cover since the line matched up with the middle crease of the cover's flap and wondered if the magnets had anything to do with it. The magnets were located at the edge of the flap so that was ruled out.
I then searched online and came across a forum with a person having this problem on his phone, and he found out that it was due to pressure being applied to the screen from the case, and that he was notified that was a common problem with LCD screens. That pressure to the LCD would cause a permanent distortion and leave a "phantom" outline of where the pressure was being applied.
I'm so bummed now, because according to what I've read there is no fix for this, besides changing the screen or just getting a replacement.
It's not that bad right now, since you have to "look" for it but it's noticeable on a white screen and it bothers me. I love the cover and think it's one of the best for the Nexus 7 but I'm afraid it might make it worse. Does anyone else have this problem? and what kind of cover are you using? Finally, I know I've said it's permanent, but does anyone have a solution for this besides changing the screen or getting a new Nexus 7?
I have a Zagg Glass curve elite never had any issues nor does it feel like it is separating from the phone screen. My issue is when using the keyboard is when i really notice it using the 0 P L Backspace and Enter it is not as responsive as the rest of the keyboard sometimes i have to go back or hit the button again it was not always like this only until recently
Things i have tried are:
Using the dialer code and testing screen calibration
Tried a different keyboard
Wiped cache
checked for updates
So is there another step to try before i go the route of factory reset but i have everything where i like it i will do it as a last resort. I could peel off my tempered glass and see if it fixes it before i reset it but then i have to request a replacement from Zagg
Just looking to see if there is anything i missed or if anyone else had issues with the zagg tempered glass over time
Just got my Note 8 four days ago. Held off a day or two before putting my Zagg InvisibleShield (glass curve elite) because I wanted to enjoy the naked screen...
I installed the Zagg threw days ago...the change in screen responsiveness/sensitivity is appalling. I noticed a substantial issue with the keys on the right side of the keyboard as you mentioned.
I feel this is 100% the result of the screen protector. There were no bubbles, it looked like a perfect install.
I have reached out to Zagg Support for answers. I will keep this threat updated with their response.
It's definitely the protector. It's not just the zag ones though. All of them do it but we just don't notice at first. I've ended ripping them all off. It just gets worse as you continue to use it.

It's many, but not all protectors... I've had mine (not a zagg) 3 months and there have been no touchscreen issues or lifting issues.

I do recommend when you get the new one installed that you let it sit overnight without using it or putting it in your pocket so that the adhesive can bond better in the installed position. Sometimes if you start using it right away the adhesive can become loose and lift away from the phone causing that lowered responsiveness. This is a bit more likely with that phone due to the curved edge of the phone and the fact that the adhesive is around the outside edge of the InvisibleShield. Another thing that might help is to adjust the sensitivity settings on the phone itself.
Well the second one was a little better, they are now replacing the second one with a Glass Curve Elite model. Difference being the Elite model has adhesive on the whole screen protector whereas the Glass Curve only has adhesive on the edges.
Wondered if anyone had done this. I am considering adding a second film protector on top of the pre installed protector from Samsung.
It says be careful of scraping nails on screen and I've noticed that it actually happens often that I scrape a touch of my nail harder than I should.
This seems like a very poor idea. It would affect image quality and might even affect touch sensitivity. I imagine it would just end up pulling up the factory screen protector anyway.

You should install not 1 but 10 or 20 more soft screen protectors in top of the one already applied!
What you need to do is remove the one already applied and enjoy the best quality of your 2k smartphone, if something happens before Dec 2021, pay the 150 and get a new inner display installed by Samsung! Enjoy at least a full year of your phone!
Ive owned both the Fold1 and now the Fold2 and being using them as dsily driver banging the phone around with tools and boxes while i do mechanic jobs! These phones are tank! My wife has long finger nails and never had a single scratch! Lets be honest, who tap their phone with a finger nail? Come on!
My 2 cents! Peace out...
Granted screen protectors are made to flex, the more you stack on top of each other, the less they'll flex. It'll cause it to stiffen and put pressure on the display. Doesn't seem like a good idea lol.

Yeap... that fold line is trouble.
It's also possible the plastic and/or adhesive could be reactive with factory one turning it into a gooey mess over time.
I'm actually thinking of doing this too. I prefer matte screen protectors to the shiny, fingerprint magnet that came with it. Maybe we could have the existing protector replaced with something else at the Samsung store or something.
