[Q] Touchscreen Issues Presses keys by itself etc... - Nexus 7 Q&A, Help & Troubleshooting

Hi guys...Just bought a N7 for my GF as a X-Mas gift and while it's great when working, there is a major touchscreen issue going on.
Let me first say I have searched and searched and came up with a lot, unfortunately it seems the problem was "fixed" by google with official updates. Well not in this case. I am on latest 4.2.1.
The issue is, the touchscreen will completely rearrange itself somehow. Example- if you click on something in the upper end it will click something randomly at the bottom of the screen. Another issue it, if you click on search/browser address bar and start typing, there is a ton of lag , and any number of things happen like, again, something else will get pressed at the bottom, or it will do nothing, and then suddenly start hitting a key (again, with the keyboard popped up at the bottom) like x over and over again, filling the page with 10-20 X's...
As soon as I put it to sleep and wake it up/unlock...it immediately goes away, just to come right back in a few minutes.
She does have a case on it with a magnet to auto wake, so I told her to take it off and see if it keeps doing it. It does...so no go there...
I want to call google for support, but am scared of getting a dumb rep that will tell me to power off the device etc...you know the drill...by the book pre-written crap they tell you to do, that solves nothing.
Any help would be much appreciated...and again sorry if this is something well known and simple to fix, but again, all my research dates back to june posts about issues already fixed via updates.
Thanks in advance!

Have you already tried a factory reset as after most recent update? You will lose all data but worth a shot. May need to RMA.

Factory reset...ok for a while..then it started again...
Got it all figured out tho....if you ever so slightly twist the body to the left the screen will not respond at the bottom and will start pressing itself randomly....sometimes even touching the bezel will do something. ..then twist it a bit to the right and all is well...
Sh*t built product obviously. Had it in a case before even turning it on.
Going back...hopefully replacement will be better.

Htc Hero 6250 screen is acting up?!

Well for some reason, at random times, when I press on my screen the notification bar will drop down. This gets annoying because It won't allow me to do anything. For example, if I were to bring up google and type something, each letter I try to type the notification bar will drop! ugh.. what could be causing this problem? is it the screen needed to be replace? any advice?
also I have to hold the phone in a upright angle in order for it to work properly. If I leave it,for example, flat on the table it won't really pick up anything I push. But as soon as I lift it up and tilt it, works fine.
I kinda have the same prob but mine will type different letters then i push and will even take overat times but I think mine has to do with the bad seal I got cause I have one of the first model's

Screen covers often times will cause this. Happened to me every few days when I had one. And fyi, I'm a mechanic, not had a screen protector in months, and no scratches. This screen is pretty resilient.

know of a step by step how to fix it? but before I do anything like that, how can I tell if I'm still under the 1 year manufacture warranty, I got this phone from private seller at a low price.

Mine did this over time eventually my touch screen just gave out and i had to go get a refurbished one
I am having the same issue with Sprint Hero CDMA. I tried clearing all factory settings, delvick cache, and anything else I could find to clear in recovery. I then used a RUU to clear it completely back to factory, still no luck. I noticed that what it is actually doing is for some reason it is sensing the touch only at the top. I figured this out while playing 'alchemy classic'. If i tried to touch any of the top icons, (for those that do not play it, these are in the same are of the notification bar) it wouldn't work. When it stopped letting me move the elements around, if i clicked anywhere below one of the top icons, it would select the icon above it, regardless of how far down on the screen I touched. I will be going to the sprint store to have them look at it, hopefully they will have decent news.

[Q] Software fix for power button issue I'm having?

Okay, so I am having issues with my power button, mainly because when I go to put my phone to sleep or wake up, it very oftenly pushes the button twice, thus I sometimes have to push it several times to get it to turn the screen off or on.
My question thus being (the reason I put this in the developer forum) is there a way to fix it via putting a delay on how often the button recognizes being pushed?
Pretty much putting a 100ms delay on each press so it can't wake up and put it self back to sleep in a split second.
And if this IS possible, is it possible without needing a custom ROM? or could I put in a fix via temp-root and push it through with ADB?
Man I thought I was the only one with this problem, thank god im not it wasnt a biggie, but it starts to get annoying after a while :/

Yeah, it seems like it would be an easy software fix. But no1 has address the issue that I've seen D:
sometimes i have problem also, issue cant be replicated but it happens....
I don't know. I just pushed my power button several times in a row and I don't see a problem. Never had since day one. Could be the way you're holding it. The button is kinda back a little compared to other devices.

Thats the crazy part, when you realize it happens, you try to replicate it and it works flawlessly, but if you happen to be just using the phone and you click the button it sometimes skips randomly.

I can actually replicate it, mine must be really sensitive. And yes, I have tried holding it many ways. I see it most often when its on my desk and I'm using it tho. but its not uncommon at all for me.
It wouldn't bother me if it wasn't all the time, but its pretty much every other time for me :[
Never had the problem until few days ago, and it's starting to happen quite often now. I'm a little bit worry being a hardware problem rather than a software problem.
Well? Whatever problem, just remember, you have 1yr warranty

I think it wouldn't be so much of a problem if we had trackpad wake embedded already, but if ur using visionary isn't there some trackpad wake/or maybe trackball wake for the nexus that will work?

Well I am sure its a hardware problem that can be fixed with software. If the hardware is sending multiple presses then software can compensate and tell it to only actually register lock presses once every few milliseconds.
My question is it possible to do it with a minor tweak to the code?
TMo already has a replacement in the mail for me because of this exact reason...The guy said I was the only person who said something like this was happening. Guess he was wrong, seeing other people with this issue makes me happy.

Yeah, I did the same thing. However, if my new one can't overclock to 1.42ghz at least, I will probably ask for another one
I want my G2 more future proof.
ditto. bump.

Yeah same here....sometimes freaks me out cuz I'm like oh no my screens black...I feel my heart fall a lil lolz

I'm glad I'm not the only one. Too bad no1 knows if this can be fixed in software.
I believe this issue is with people who did the temp root and OC'ed it to 1.42ghz. I noticed when I press power to unlock the screen, the screen will not light up right away, than it does for a faint second and shuts back off. I have to press the power button again and the unlock screen shows up. I hope this does not cause any other issues with the phone. Otherwise ill have to leave it at the stock speed.
I have had this issue since I got the phone, so it's not anything to do with overclocking.

[Q] Dead (?) screen strip

all right. I've found various things about this on the web regarding other HTC phones, but I can't seem to find if anyone else has had this problem with their shift... This morning I realized that the "clear" button in the notification dropdown on CM7 wasn't working for me. I wrote it off as a weird bug. But then I tried to play angry birds, and I can't drag them back, they just fall right off the slingshot.
So I zoom in and I can pull the birds back, but when I get to this strip on the screen, they fly off without my picking my finger up.
Besides the clear button, screen presses generally seem to work, atleast when I'm selecting icons in landscape mode from my home screens. But the n1 style live wallpaper will respond to touches in this "strip" of screen by shooting off the lines around it instead of in it. Also, when I tried to drag to a different homescreen and stop in this strip, it will bounce back. same thing with notification bar. If I try to start dragging the screen from this "strip" I get no movement. The weird thing, of course is that this part of the screen isn't completey dead in terms of responding to touches, because it does register on my device that it is being touched, but drags, the notification menu clear button, the live wallpaper, and, of course, angry birds act funky when I use this part of the screen.
I guess I have to go back to sprint. I think I'm just going to flash a stock rom, but not unroot it.
I also don't have time, so I'm kind of just hoping it will go away.
ANYWAYS... anyone else having touchscreen issues with their HTC EVO shift?
PS: I think clocking my kernel at 800 instead of the 1200 I was using might have something to do with this?
Was running at 800 to preserve battery life, but back at 1200 after a nandroid restore and the problem seems fixed.
2 be clear, I had this issue on CM7 and MikFroyo, so I don't think it could be software related. But CPU clocking related.
Yeah, I also doubt that is the case.
My screen had a freek out. With out touching the screen it would open and close apps jump screens and when I touched the screen I would get no response at all. Had to RUU and send it in for a new phone it was in the connection with the screen. So the sooner you ask for a replacement the better.

did you just call? any tips? I'm wondering if I can handle this over the phone or not. Also - what did you do while you were waiting for the new phone to come in?
turns out it was the friggen screen protector. however, before I realized that I called my local repair shop and they said that they would be able to swap my phone out for a new/refurb one for $35. Too bad it isn't actually an issue, because I've noticed that the phone is a little less responsive to touch even with the screen protector off... it's just that its not clearly an issue at this point.
I actually had a similar issue with a replacement phone where the left side about 1/8" wouldn't respond (couldn't press q button on keyboard at all). After some research I found out about a great lil app to test screen touch response and any bad areas and it helped me diagnose that it in fact was the screen having a fault...look up "touch test" in the appstore and it should narrow down where and if your screen has a bad area that's not responding...it helped to get my in-store replacement in and out the store since I could show them the issue right away along side an in-store model. I hope this helps and I that I read the post correctly. Let me know if it helps you.

My screen had a dead line going across the middle of the screen but only when swiping side to side, for some reason vertically it was fine....
unrooted, went to sprint store repaired in less than 30 minutes...

No problem...glad to help...it definitely saved me time...I installed it on my phone and the stores phone and compared them side by side...that way they can't give you a BS answer of "screen needs calibration" etc etc. Lemme know how it goes.

Sorry didn't respond faster. I just called them and they sent me a new phone next day and I sent them the old phone. Easy as pie no problems with the reps or the techs they didn't argue about it at all. It did take a long time on the phone because they were checking the phone settings no sure what this was but oh well. Just remember to ruu back.
Killer Shift
So they ended up still pretending that there wasn't an issue, saying that maybe it was just the touchtest app. It took a while to convince them that it wasn't just an app.. but after I left it with them for an hour (an hour where I'm sure they did nothin) I came back and showed them the issue again, compared it to the shift that they had, and they finally agreed to order me a refurb. A hassle, but a necessary one.

Agreed..It's awful how there is no set policies when it comes to service. Your fate pretty much rests with the tech you happen to get. Some are easy to get along with and some (obviously) aren't.

The Refurb is great... oh, and FYI - don't use displex on touchscreens hahaha.

Help.. URGENT help.. I cracked my screen.

So my Nexus had the screen lift.. I was just curious, and wanted to see the back of it.
Took the back cover off, no problem. I didn't really do anything except look around. When I wanted to pop the back cover back in, I had trouble with one corner.. it just wouldn't pop in. So i pushed that corner a bit (I swear I didn't really use that much strength) but I turned the device around and saw the corner of the glass was cracked. It didn't reach the pixeled part of the screen, it was only at the black border.
So I thought- ah.. oh well it was my fault. I was pissed.. but who was I to blame right? I'll just live with it.
Here comes the problem.. I pushed the Power button, the lock screen came on as usual. However, it seems to have absolutely no response to my touches at all. I tried touching every single corner... NOTHING.
There is absolutely nothing I can do with this device right now.. Except 1. power it on, 2. take a screen shot.
Can anyone tell me what to do now? I've taken the device out of the states. The country I am in do have Asus office. I know the warranty probably does not cover this. I would be willing to pay for a new screen- but does anything know how much it will cost?
Sigh.. any help/comment would be nice. I'm totally devastated right now. I know it's my fault for not being careful. But I am able to go traveling next week, and was looking forward to reading books on it etc.
If it were me, I'd send it back and get a replacement since it had screen lift and that was the only reason you opened it...

Well I'm not in the U.S, and won't be anytime soon. My friend bought it over for me. Tomorrow I will call the local Asus office and ask them about it.
In the meanwhile I might just buy the micro-USB to USB cable, and use a mouse to control it. Although That will look ridiculous as I'll have to find a flat surface to use the mouse everytime. Is there some other USB controller I can use to control the screen?
Also I don't really know much about digitizers.. once you crack one corner, does it mean the entire thing is not usable anymore?
I had very small screen lift issue. Barely noticeable. But with this official nexus 7 cover seems to keep it down

Yet Another Hardware Problem?...

Hey All,
I did a quick search through the N7 forums and didn't find anything, so I'm going to throw out yet another effect that I'm hoping some of you hardcores out there are experiencing: When I apply pressure to the lower left hand corner of the tablet (left and bottom bezels, tablet upright with camera on top), it blanks and screen locks; it sort of fizzles a bit and I have to reopen the screen a few times using the power button to bring it back to a stable, open state.
You might say "don't hold it there." Fair enough. But that happens to be one of my favorite places to hold it when I read a book, so it'd be a bit more of a change than I'd prefer... Suggestions on how to fix it would be great.
Thanks!
John
