[Q] Ghost touching my screen!

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.

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.

Galaxy note broken screen after only 2 weeks: anyone else?

Hello. I bought a galaxy note on 28th november. After only 2 weeks of absolutely normal and careful use, my screen is scratched and broken. Ok, it is a small crack, but it is not good.
It never fell and it never hit anything. After only 2 days, i noticed some scratchs and some other came in the days after. Then, the part of the screen between the upper edge and the speaker broke in two, with a crack (small, 5mm but still a crack) going from the edge to the speaker. I can't post a photo as i sent it back to samsung for repairs (it had also display issues). Do you know a reason for it? It should be gorilla glass, and i only kept it in my pockets without anything inside apart the smartphone. Do you think samsung will repair it since it happened during normal use after ONLY 2 weeks? I'm really annoyed and disappointed.
Anyone experiencing glass resistance issues?
Thanks

Call samsung and send it in they will fix it..

Yes, i did it and i'm waiting, and i also adressed the lines issue and the green/banded screen, but i am in italy and i'm not sure if it is covered by warranty, it should: they can say i broke it.

The Corning Gorilla Glass was one reason I went with the SGS2.
The other reason was fear of provoking the wrath of God for having such a sensationally beautiful device (the Note). It's an awesome device, really.
But God smote those who worshiped a golden calf, too.
lol Sorry, I'm not really a religious fanatic. But yeah, sucks about your screen. Hope Sammy fixes that one up for you.

Welcome Nickelsilver and please don't take this personally and in NO way I'm defending Samsung or the Note but I have to say the neither scratches or dents/cracks come by their own.
They just don't happen/appear magically by themselves on the phone's screen/body. Maybe someone is messing with you Note without you knowing it?
E.g: I have 1mm small and barely noticeable scratch on the top left corner which I suspect it came from the ONLY 1 time my Note slipped from the passenger's seat and fell in the gap between the passenger's door/seat.

I went through 3 screens on my dell streak. Now that I have the note which is even bigger I was so cautious I treated it like a delicate fragile little flower. Needless to say after 2 weeks I noticed what appeared to be a scratch going up from the bottom middle halfway up. Turns out this is not a magical scratch that sprang out of nowhere but an actual crack on the outer glass screen. I have never dropped it but perhaps it was somehow flexed.
No warranty of course. I have ordered the glass itself from overseas and when it gets here in a month I suppose I will try replacing that piece individually as its only the outer glass that seems cracked. Hopefully they do not glue the screens together like they did in the streak ><

To OP: im sorry to hear that....hope samsung can fix it for you quick.
Ps. Dont listen and worry about this guy...he thinks only his opinions are important and others experiences are just JUNKS and BORING! Not sure why he would even bother to reply, if they really bores him that much. Maybe he really thinks that he BOOFY the witch hunter or something
Plus.. He forgot that he has also once posted a question regarding to his screen problem too here on the forum.

Gorilla glass is bull****. I had dell 5 streak, and I changed the screen more than 5 times. Little drop will result in screen loss. Do not depend on gorilla glass.

My Samsung Galaxy Note are broke
Yesterday I was knocked out of the hands under my 40 days old Samsung Galaxy Note, the cover glass is cracked along its entire length as a spider's web, while the LCD screen is not damaged, that still works, receiving the touch command. The solution I found in the orders of the new protective glass over eBay. Maybe that was too much angry because it happened to me, but NOTE is too amazing, and I somehow survive.. I'll let it be when we come new safety glass

I do not think this is a witch hunt. More of an informative thread on one weakness to an otherwise amazing device. It may be that until an indestructive clear glass is created that we will continually face this on any large phone. Anything this large will flex easily and likely crack. One thing Samsung definately did right was not glue the glass to the LCD behind it. I put a clear screen cover over mine and you cant even see the crack anymore. Were this a dell streak you would have half of your screen blacked out.
This is definitely the best mobile device out there in my opinion, people should just be extremely cautious with where they carry it. Mine most likely cracked in my pocket from slight flexing.

The glass on the note shouldn't break even when flexed unless it's not Gorilla glass.
Gorilla glass is not only scratch resistant,it is also shatter resistant.
If the glass is breaking frequently on the notes,then I wonder if they really have Gorilla glass.

That demonstration glass at the beginning of the video is about 3 times thicker than what Samsung uses on the Note/Galaxy S2/Galaxy S SAMOLED panels. And it's quite a bit smaller, height/width wise (it's about iPhone 4 sized).
Thickness makes a significant difference in flexibility and shatter resistance. Which is off on a tangent, because the main reason Samsung and others uses GG and similar techniques is not for shatter resistance.
It's almost entirely for the combination of higher scratch resistance vs metals (all bets are off with sand particles) and a better tactile feel (it's smoother) than non-treated glass.

Sure it may not be as thick on the note but you are never going to flex the phone anywhere as much as that demonstration.
My point is that if it is gorilla glass,it shouldn't be that easy to crack the screen given the abuse that it is supposed to be able to take.

All these? Gorilla Glass
And all these? Gorilla Glass
How about all these? Gorilla Glass
Or maybe all these? Gorilla Glass

It's been 10 days since i bought "the Note". I dropped the device just once from 1 meter height. It was a free fall with not much impact power. The screen has a crack on the upper right corner. I know every product is meant to last but so easy , so fast ! ??? Thankfully it still works with no functional issues. It's just the protective glass on top of the actual LCD that is broken. But u can still feel it while wiping your finger and it is appearent...
Hardware wise The Note is simply outragous but when it comes to software and durability it can't even come closer to what i used to find on HTC devices

The weight of the note will count against it during falls compared to say a very light phone like the SG2.Impact is going to be much harder if they both fell from the same height especially given te size of the notes screen.
Until they can make the note lighter,users will just have to be more careful not to drop it.Gorilla glass is not unbreakable.

I get my note tomorrow. Now I'm all paranoid

"Ghost touches" and screen protector?

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!

Displayglas failure on the left and right edges

Hey community i own two Nexus 4 devices and both have the same problem... Two different bags and one SGS 3 were needed to recognize the problem specially on N4 devices. The left and right curved edges and some parts of the rest of the display are very sensitive of wear.
How I recognized this?
I wanted to clean my display.
If i breath on it, spots will appear who wont mist that much than the rest of the display.
This spots are not removeable and susceptible for dirt and fat fingers / fingerprints.
The SGS 3 , that has the same curved edges hasnt got this problem althrough it has the same kind of glas : gorilla glas 2
My first N4 had this problem on the left side to the middle of the display where i scroll the homescreens with my finger.. My second N4 has it symmetric on each side after 2 weeks. A displayprotector holds back the wear of the rest of the display.
I sent an email to google and reported about my problem. If you have recognized the same kind of s**t , please post a reply and where these spots appear. THANKS

Most likely the oleophobic coating is wearing off in those places. It happened on my Galaxy Nexus and its starting to happen on my Nexus 4. I have a bumper on so the edges are fine. Its wearing where it rubs against my pants pocket.

No problem here after 2 months +.

@ el daddy : sorry but this normaly happens to a 1 year old device. mine are one month and one week old. and that homescreenscrolling causes such spots.. in light use after one month.. like i said... SGS 3 same glas, same curved edges, havnt got that problem

I don't get why you are condescendingly apologizing to me. I was just telling you what was happening and that it's happened with my last two phones. Yeah it's annoying, but there is no time frame on when it should or shouldn't happen. It doesn't matter if it's brand new or 5 years old. Enough friction will cause wear.

AW: Displayglas failure on the left and right edges
and thats the point. one month light usage. and the finger causes enough friction to wear the screen like a streak of 1 cm * 4 cm from the edge to the middle? i cant imagine

same problem
i am getting this on about a quarter of the screen, where the coating has obviously worn off. it must be from going in and out of my jeans but ive only had it for 12 days. kind of a shame, its most noticeable in bright sunlight, with low screen brightness.
do you think putting a screen protector over top would even out the appearance of the coating and hide the area where its rubbed off?

AW: Displayglas failure on the left and right edges
yes a screenprotector helps to hide the worn spots. This afternoon i will post some pictures of the screen that will proof that this problem is caused by a manufacturing failure.
This are pictures of my second 1 and a half week old device. If i hadn't put a screenprotector on the display, the half of the screen would be rubbed of now.
In this picture you can see where the worn spots are.

Such a symmetry isnt caused by natural wear... It is caused by a differend degree of hardness all over the glass.

All your links are broken but it doesn't matter anyway. I'm honestly failing to understand the problem here? It's just the anti-finger print coating which is laughable at best at doing what it's supposed to do anyway. The only time you notice it wearing off is if you breathe on the phone.

You got any pics? the ones 2 posts above mine say they permission denied

I've got an old sgs that I never put a case or screen protector on and carried round in my jeans pocket for over 2 years without any wearing out of the screen coating. I've got a six month old razr maxx again with a perfect screen even tho it's been in my pocket without a case or screen protector. I've got a 6 month old n7 that I use all day long every day and which is constantly in and out of a neoprene sleeve that has a screen as good as the day I bought it, which hardly shows any finger prints and which I clean about once a month if that.
Contrast that to the 2 month old n4 that has half it's coating missing (although not in a pattern that could be caused solely by wear - it looks more like it was never applied correctly). I have to wipe the screen clean every time I use it and five minutes later it's filthy again, but only on one side - the other side is pristine. The dirty side is noticeably rougher too when swiping. In daylight the finger grease is enough to obscure the screen, so that I feel the need to clean it.
It's clearly either faulty or not fit for purpose. My gut feeling is that if applied correctly to a properly prepared screen, the coating should not wear off in normal use.

I really feel for you guys but there's no way to determine if x or y phones coating will wear off. I don't know if its the specific coating that Google uses or what but this has been known to happen on the nexus s and the galaxy nexus as well. As for your jeans... Jeans are actually very abrasive as they attract dirt and soot into the fibers and it acts almost like a strop on the glass repeatedly taking it in and out of your pocket.
I don't trust the glass on any of these devices and though the screen feels really nice on this phone... One of my RMA phones shipped with a big dot of a scratch or defect in the screen right from the factory. I never use any of these devices without a screen protector. I use bse as they mostly preserve the feel of the screen sans protector but if you want a less worn screen... On any phone I would suggest that be one of the first things you get for your phone.

Mine's exactly the same even down to the not worn spot in the middle of the edge. From how I use and carry my phone there is no way this is caused by normal wear and tear. My replacement arrived this morning so I will see how it compares tonight.

I think these little bugs are caused by the low price of the phone. reducing the costs of a phone causes bad quality...

Homescreenscrolling caused this

Is no one else getting dozens of little scratches on their screen?

Had a note 3 for 2 years with no screen protector and heavy use, not a single scratch. Within 3 days of owning the note 5 I've got dozens of tiny ones and two sizeable ones! I've ordered screen protectors now but obviously too late. I'm a bit confused as I couldn't find this being a common issue and I haven't changed usage habits (phone always gets its own pocket, rested on a piece of foam at desk)

Same here. Previously use LG nexus 5 without screen protector for a year plus, just a single tiny chip.
Note 5? Just a week without screen protector and 6 visible scratches there already.

I wish ANY of the reviews had mentioned this so I could've taken preventative action.

Same here guys. It's really annoyingn barely putting it in the pocket, you find little little scrstches.. bare annoyingly annoyijg

Try not putting it in a pocket with objects that can scratch the screen.
No offense, but I've never had one scratch on any screen, nor any cracked or broken screen (and never owned or used a screen protector), since I started using cell phones back in 2000.
