Hey All-
I searched for this with the assumption that with all the N7 screen issues there would be others experiencing this but I was not able to find much of any help.
----
My N7 is registering touches without me making contact with the screen. It is always in the same location. When the keyboard is up, it is where the letter 'D' is located. If I pass my finger directly overhead, or often times, even near to, the 'D' button, the tablet registers it as a touch. I can make the tablet register a touch with my finger as far as 1/4'' away from the screen surface. As you may imagine, this makes typing near impossible. As I pass over the letter 'D' to access other letters, it registers 'D' everytime.
I have tried other keyboards and the problem persists. It isn't necessarily over the same letter (due to differing keyboard layouts) but it is always in the same location on the screen.
I popped the back cover off and tightened/loosened screws to no avail. Turning the screen off and then back on does not help as it seems to do with some of the other screen issues that others are experiencing. The one thing I have found to strangely help is pushing on the screen in the affected location with extremely firm pressure; in essence squishing the s*** out of it. When I do this, the screen will behave better (it will still ghost touch in the area but my finger must be very close to the screen) for a period of time before reverting to misbehavior.
--
Has anyone else experienced something of this sort? I am currently running stock/rooted/unlocked; It seems to be a hardware issue so I don't think another ROM will help though I will try the CM10 nightlies when they boot properly. I'm ready to just bring it back for a new one but I know the Wal-Mart I bought it at is out of stock.
Any help would be very much appreciated, thank you.
Im having the same issue mine is in random places, usually top left corner but when im texting it starts typing random letters, I've been looking
for a solution or someone with the same issue you are the first and only that i have found. I am also having the dead spot issues, they tend to alternate.

Nexus 7 phantom taps
I'm having similar problems with my Nexus 7 bought in November. Worked fine for a while, now I'm getting phantom taps making typing a real pain and page scrolling can be frustrating when it suddenly scrolls to the top of the page! Anyone know if this is a warranty fix?
I had this happen one time. It freaked me out.

OP and others - have you look at the video here - post #1254 - look familiar to you at all - http://forum.xda-developers.com/showthread.php?t=1770919&page=126
A # of us had been freaked out, wondering if our secured WPA2 network has been breached and remotely controlled ...
If your device is brand new, return it & get it exchanged, or get it fixed under warranty - it's hardware related. The 16GB WiFi only model that I got from local Staples store had that problem that got worst - the replacement & upgraded 32GB unit has been flawless thus far - running stock but rooted 4.1.2 rom. I was within the 14 days/holiday time frame for exchange/return w/o stocking fees, luckily & did not have to wait for it to be repaired under warranty.
Upgrading to 4.2 firmware and/or custom Rom & kernel do not help, YMMV - of course ...
BTW, local Staples tech support counter manager said up to 20% of the N7 are getting returned/exchanged for various issues. Wow !!
After 4.2.2 my nexus7 makes phanton clicks too
Similar with this video www.youtube.com/watch?v=Tkh3W_ITwEw
I turn off screen and turn on and stop... The times in times i get it
Have solution?
I had to take my screen protector off after the update it was pressing places on the screen didn't happen until 4.2.2 update

Maybe this is either a really stupid question or not even a question at all, but i have my ideos x5 u8800 with the atmel screen, and i have flashed both the dzo s aurora ics and after that i have passed to the cm7 .35 kernel, and both of them have the atmel fix.
Now, what i expirienced was that on the first couple of days, with both roms the screen functioned just fine, i played several games including modern combat 3 and all was smooth. but after 2 or 3 days i was playing because it is what i do most and the screen started to go absolutly crazy, i mean, in MC3 the weapon started to fire without me putting the finger on the buttom, when i wasn t playing the phone was selecting and opening apps without me choosing, and sometimes when i tried to unlock the screen i just couldn t do it.
i would like to know if possible, if the atmel fix really don t work to well, or if maybe is my phone that is all messed up, so that i can decide if i take it to the technical assistence or not.
Like i said, if it is a stupid or inapropriate question to make here, then i appolagize in advance, just please don t be rude on the answer.
Thank s in advance.
To me, it sounds like your touch screen digitizer might be breaking down. My phone experienced similar symptoms before my Symantec digitizer broke: It would pick up widgets even after I seized to touch the screen. (Warranty replaced it with an Atmel one. :crying
To determine if this is the case, go to system settings > developer options > turn on "show touches" and "pointer location". You should see these ghost touches after this(?). (This is on Aurora ICS. If you are using another ROM without such functionality, you can try something like this.)
Of course, I don't mean to scare you, so you might want to try going back to an official ROM as well.
I have been using Aurora ICS for ages now, with and without an Atmel digitizer, with the official kernel, and for the past two days, this one with no problems. Clearly I am not taking into account the time my digitizer broke and the problems it caused.

i am sorry mate, but i really dont understand much of this. so i did what you told me, and where i touch is exactly where the grey circle ( i assume that is the ghosts touches you said) appear. so is that good or bad?
sorry for my total ignorance.

My plan was to leave the pointer location running whilst you do your daily activities or play games in order to find out if there are additional touches - besides ones made by you - visible on the screen. If a touch registers on the screen without you making it, it could be your digitizer acting up. The grey circle under your finger is what should occur after you have switches "show touches" on; it's normal behavior.
Shortly after the symptoms you are having, the whole right side of my screen stopped responding to touch altogether. You may want to return to stock, and if the symptoms still appear repair it while you're still within warranty.

Hi. I have had my Nexus 7 for quite a while now and so fdar it had worked perfectly. However today the touchscreen wouldnt work, even after many restarts. Then it suddenly started working again. I flashed back to stock and till then everything was working good again. However once I flashed a custom rom again the thouch screen got messed up and it was as if I was touching the screen when I wasnt. Does anyone know what's going on with my tablet ?
Thanks
I was mistaken when I thought it was related to software and I found the real issue. When applying pressure on the left side of the frame of the tablet, the screen will start registering touvhes on it's own. Upon using Multitouch Visualizer I noticed that after i pressed the left frame of the screen, the tablet would register touches on the far right of the screen on it's own. Is there any way I can fix this ?
My phone last week wasn't receiving texts so I restarted it and when it came back on the touchscreen no longer worked. The little white light would go on when I touched it so it knew where my finger was but any movement would not unlock the phone so I couldn't actually do anything with it. Sure enough a factory reset fixed the problem but I am still waiting for them to get me a new one in case the problem happens again to me. Anyone else have this happen to them or just a freak occurrence for me?
My son has gotten a hold of my s4 twice now since I have owned it. Both times I couldn't get the phone unlocked even though the touch screen was recognizing my touch. Restarting fixed it both times for me. Not sure if this is the same problem you are talking about, just thought I would share.

Happened to me a few times. Both screen swipes and the capacitive button presses werent registering. Happened on lock screen, call logs (swiping to call wasnt working), and swipe to answer. Pressing the home button and going back to the app fixed it. Very random but annoying nonetheless especially when not able to answer a call
Seems like buggy software to me. I've had a different issue, my phone says I have data, but I don't, I've had to restart the phone to properly pick up a data signal. This has happened twice now. Seems to be like Samsung's touchwhiz is quite buggy...
Yeah restarting it did nothing for me, tried many times, took the battery out put it back in all that stuff. The same thing happened with my data, I had a connection that entire time that I was not receiving texts but none of them actually went through which is when the problem began.

What app were you able to get in to to fix it? Would like to know in case the problem happens again when they get me a new one.
This happened to me last night, about had a major freak out.
First I have a couple questions for all of you who had this issue, so maybe we can pinpoint the actual cause:
1. Did you get any type of moisture (even just a little condensation) anywhere on or around the phone? Mine started acting up after I accidentally put my phone on the coffee table where some condensation had formed from a drink being there previously.
2. Any of you drop your phone at all? Even just a minor drop...as the day before I had a little drop (maybe from a foot off the ground), but I do have a case.
The reason I ask is because I started having this issue immediately after the phone was put on the condensation. Don't know if that was the cause, though, because I'm not sure exactly which of the steps below actually fixed it.
First I had to identify the exact problem...which I found by turning on "show touches" in Developer Options within the settings menu. This brings up a little white dot on the screen any time it registers a touch. Sure enough, I was getting "ghost touches" on the top left corner of my screen every 30 seconds or so - and it would generally last for 10-30 seconds or until I turned my screen on and off (that would fix it temporarily). The ghost touch was causing my drop down menu to pull down slightly every once in awhile, as well as not registering any of my other touches (including capacitive buttons). I knew the screen itself wasn't broken, because any addition touches were registering via the white dot - they just weren't interacting with the UI.
After doing some research online, apparently there are a couple main reasons that this ghost touching could occur:.
1. Faulty digitizer. Obviously this would Suck, and I really hoped it wasn't the cause. To repair would mean replacing the entire screen, as apparently the digitizer is attached to the screen and would be very difficult to replace by itself.
2. Any kind of moisture, whether water, skin oil, etc, getting in the cracks of the phone and staying under the screen, causing the pressure to indicate a false touch. Possible repair options included putting the phone near a WARM (but not too hot) surface for a period of time to hopefully cause the moisture to evaporate. Also some people said it just evaporated on its own after a few days (again, I hoped I wouldn't have to resort to this as I'm impatient and don't want to be without my phone for that long lol).
3. Software issue. Possible fix includes toggling HW overlays and/or GPU rendering.
Here's what I did:
Took the phone apart completely, made sure there was no visible moisture anywhere (there wasn't). Intermittently blew the phone (from the back and front, while it was disassembled) with warm air from a blow dryer. Left it alone, disassembled, for about 30 minutes.
Put the phone back together, booted up, immediately went to developer Options and (a) disabled HW overlays and (b) DISABLED "Force GPU rendering" (I actually already had it enabled).
BOOM - problem was gone!
So like I said, I'm not sure which of those did the trick - or which problem I had to begin with - but I'd be interested to know if anyone else had similar issues and/or fixes?

I should not have had any condensation at all on my screen when it began. I was using the phone playing with WatchOn and setting it up for my TV, I was messing with it for quite a while and realized after a period I hadn't received texts in a long time (I normally get at least 1 every 10 minutes, I was going on a hour and a half with 0) which I thought was weird so I restarted the phone.
When the phone came back online I did not notice the white dot pressing itself anywhere, but anytime I touched the screen it would immediately know where my finger was and follow it around, but not actually press anything. When I held the power button and the little Shutdown and Restart options came up, if I sat there and just pressed either one of them constantly they would eventually recognize that I pressed something and do that action.
I was also able to get into the homescreen by getting the talk option to come up and backing out of it (The buttons on the bottom of the screen all worked fine) but once in the homescreen I couldn't actually press any buttons regularly so gave up on it.
The guy at the ATT store said he hadn't seen any other complaints about it so I did a factory reset while there (I had already backed up everything with Kies) and when it came back on there seemed to be no problems.
Like I said though I am waiting for a new one anyway, they are backordered at my local store (Should have got a new batch in Friday, not sure where my phone is now) so hopefully the new one I get doesn't have this problem nor the lag problem a lot of people have been getting.

Just the stock Phone app. My problem seemed like a software problem more than anything else.
But if you have to restart the phone in order for the digitizer to respond, thats a different story. A swap should fix your issue, since it seems so uncommon.
Hi,
I am having a serious touchscreen issue with my Note 3,
I am getting ghost touches, which happens occasionally but sometimes goes crazy,
It happens in a specific area of the screen (exact area, between and over QWERTY and ASDFGH rows when typing),
It appeared after a month from purchase,
I have submitted it twice to Samsung service center without getting it fixed,
1st time they changed the charging port!!!
2nd time they just reset the software !!!
What should be the solution to this issue ? is it a usage issue - I never dropped it ?
Final note, lately I noticed that I can trigger these ghost touches to happen by pressing (with some little pressure) on the top left corner of the touchscreen.
Below video shows the problem,
http://www.youtube.com/watch?v=1TqjQD99tMk
Update:
I have submitted it today for the 3rd time to Samsung service center, I hope I get it fixed this time.
They said that they will replace the LCD screen, should that fix my problem ?
LCD screen has a touch pad build in and from your description seems like there was a short somewhere inside the screen so this should fix it, but frankly service center should read your complain and test it for this particular problem before giving the phone back to you, the first and second time around unless it's something hard to reproduce. You can only hope third time is a charm.
