I know that this has been a fairly common complaint about the Nexus One but i'm wondering, roughly what percentage of people actually have this issue? To clarify, i mean the problem whereby touching the screen in one place is actually registering elsewhere on the screen.
I've had this problem since buying my n1 and having to constantly turn the screen off and back on again was driving me nuts. Finally i sent the unit back to Vodafone for repair and they in turn sent it to HTC to be fixed. So yesterday i got it back with an enclosed statement along the lines of "we have fixed your fault etc..".
Three minutes into using the damn thing and the fault crops up again. So much for that! To be fair to Vodafone they are sending out a replacement unit now but of course i'm concerned that even that will have the same issue.
What are the odds?
Here is the same.
To developers: the fact that resetting the screen fix the problem makes me to ask if there isn't a way to make the screen re-calibrate itself every X seconds/minutes, without shut off and on the screen every time. Seems to be until now the only solution to this extremely annoying issue.
It really is a bizarre one. I've seen people discussing whether it's a hardware or software issue but nobody seems to have a definitive answer. If it were a hardware problem, surely it would be constant/permanent? If it's a software issue i would have thought that somebody would have bug-fixed it by now? Especially as it seems so prevailant.
I'm stumped!
Other than this one problem though i am completely in love with this phone. The device itself feels solid, durable and pleasant to use. Android is improving all the time and it always impresses when you demonstrate to the un-initiated what the device is capable of. So close to perfect...but not quite!
EDIT... This from the wiki.. "- Q5: Sometimes my screen registers touches in incorrect places, and I need to turn the phone off and on to make it work correctly again
A: This is a hardware problem, nothing can be done about it. Nexus One's digitizer sucks.
Ho-Hum.
I have experienced this problem on android 2.1 ever since upgrading 2.2/2.2.1, I haven't had the problem. I'm very happy with my screen

That suggests a software problem although i have had it on 2.1, 2.2 and now 2.2.1. I would say that it has happened to me within three minutes of using the phone, 50% of the time within that three minute window. In other words it's cropped up in half the texts/emails i have sent where i have had to do the screen off/on thing to complete the message.
Very annoying.
It has to do mostly with the way people hold their phones, the possibility of registering false touches - including, for example, touching the screen with fingers that aren't completely dry. Some have the issue more than others.
HW issues still can have SW workarounds sometimes. I'm not sure if it's the case. HW and SW need to be analyzed to find one, if exists.
There is no "calibrating" capacitive touchscreen. Resetting its controller might have effects like missing touches and other random screen misbehavior (for example - if the controller is tracking fingers, resetting it would cause it to lose the tracking).
Since getting my phone back from 'repair' the issue is less frequent, suggesting that it's not a usage problem as i'm obviously still using the phone in the same manner as before. Instead it seems that various devices suffer from the problem in varying degrees.
I suppose if i knew what they had actually done to the phone while it was being tended to it might help us discover why the frequency of the problem has been reduced. I know that the digitizer wasn't replaced as the phone came back with the same screen protector on it as it had when i sent it off. That being said, they obviously did something. I just don't know what!
Most probably replaced the phone's MB.
Try upgrading to the latest radio - the issue will probably not be 100% solved, but now I only get it maybe once a month or so...
I may tell them not to bother sending out a replacement. It's happening far less often since it was returned and (going by the poll results), there's a good chance that the replacement could actually be worse than this one is now.
Perhaps the 2.3 update will jar something loose.
ATTENTION PLEASE!!
after flashing miui latest ROM i've never had touchscreen issues anymore in over 20 hours of hard usage (also with the phone in charge!!).
I don't believe is a coincidence, developers please ask miui developers if they have integrated a code to fix this issues.
Thanks!

I have already restored cyano 6.1.1.
However, about "multitouch issues" I mean inaccuracy, the fact that the touch is recognised in another point of the screen (particularly when you press the bottom part of the panel). I didn't verified the axes-inversion issue, but I'm almost sure that it persists.
The "touch inaccuracy" is nothing else than the usual axis-swapping thing. When accidental dual touches (palm/holding fingers/water/etc) happen, the digitizer goes nuts.

I don't think so....I pay attentions when the screen goes crazy. I'm absolutely sure that (in charge for example) my touch is ONE.
The only times I was able to trigger the "screen nuts" effect, were when I was typing 2-fingered, and fast - making it register dual touches. Moreover, sometimes a single touch with a single finger is reported as series of touches. Once it happens, it stays until screen off.

I mean this....since I moved to MIUI this is not happened anymore.
Since I uninstalled Htcime the inaccuracy issues seem less so far! Almost only with the phone under charge ...much much better than before! Dunno why....

Is there any programme to for screen calibration? So part of the screen seems not responsive.
That is a hardware issue not a Calabration issue..
does somebody know if this "hardware issue" is present at all note's?
i found that my screen is a bit unresponsive at the top right corner. i cant draw about 2mm to the border of the screen (with the pen)!

However when I flash a new rom the screen get responsive for a short while. After that I need to press the screen harder. On the bottom right hand corner has this problem.

Did you ever solve this problem? Mine started doing it after it updated KL7 OTA.
Well guys I'd like for someone to chime in on this. I thought for sure this was a hardware issue. I'm on my second note now. My first note seemed like it was having issues with the lower right corner of the touch screen. I thought maybe it was a rom issue. I flashed clean KL7 and it seemed to suddenly be better then after a little bit it got worse. I have my second note and I flashed KL7 right away on it. Now after a little bit it seems to be getting less responsive, still better than my first, but I'm beginning to think this is a software issue. Any of you having these issues what Rom are you on? Should I try changing out this note for a third and see what happens? I may flash to some other firmwares to see too.
my top right is a bit unresponsive as well. . it works but seems a bit off. .
I used swipepad , really useful taskswitcher
It does not work when phone is connected any charger.
I've definitely noticed the phone being less responsive when on the charger, but this seems to lose responsiveness over time off charger and on battery.
I've had other phones that from time to time would act a little wonky when using them while charging.
Hey,
I've had some display problems, both with regards to calibration and also when it's charging.
I have made this video to demonstrate a problem I have of calibration. Watch how the display detects a signal at a point offset from where I press with the pen.
For me the problem I saw using the *#*#2664#*#* test is that the last 10 pixels or so on the 2 end sides of the screen don't respond.
For the pen offset is cause of the left or right handed settings, I find that holding the pen and rotating it so that my thumb presses the button of the pen instead of the indicator finger gives pretty good accurate results.
I'm definitely thinking this is at least more software related than hardware. I don't remember noticing any problems when on KJ1 or KK1. So I flashed back to KK1. It started it up and then I did a quick factory reset. This is completely stock/unrooted. Anyway bottom right corner seems to be having no problems detecting my touch now. I'll leave it on this for a few days and play around and see if it seems to lose sensitivity again. If it does I'll let you guys know, but for this to be a hardware problem I can't imagine it being this intermittent. Any of you on KL7 that mentioned this issue, are you guys completely stock KL7 or using the CF-Root Kernel? I know someone mentioned losing functionality in music player and torch and it seemed to be an issue with an alternate kernel.

That´s normal - pen is calibrated to use it at a certain angle - try to change the setup from right handed to left handed and you will see a different offset if you make the same test again.
The offset should be the same on each area. Only if this is not the case i would say, there is an issue with the screen.
Hey, ok so it is a deliberate software decision. Kinda sucks- I'd think I'd sooner like to have it type directly below where I write. I'm guessing it is an attempt to account for the fact that the glass has a finite thickness. Sooooo does anybody fancy writing a kernel alteration for this...?
i also find it more annoying than useful
Couple days on KK1 and what I thought was a hardware problem still seems to be fine. It's detecting much better in the bottom right corner where I was having issues on KL7.
I am having the same issue with the reduced responsiveness of the bottom right corner. I've noticed it after updating to KL7. Maybe is the driver of the screen.
Is there any way we could report this back to Samsung?

Hello.
I have the same problem ate bottom right side of the screen. I am ate LA4.
what should I do?
Although the problem was nearly imperceptible some days ago, while the note was connected to the charger, I've noted a very small area near the bottom right side of the screen where it was difficult to write using the stylus with SMemo. On the opposite side the loudspeaker is present; and so I've thought it might be correlated with the magnetic field of the loudspeaker. Today I've performed the *#*#2664#*#* test with and withouth the charger, but the problem is not occurred. Because of these devices are always more complex I prefer snap closures for my cases.
Every couple of days I have a problem with the screen becoming VERY unresponsive. It seems to affect the whole screen and requires touching characters on the keyboard, web buttons, app icons, etc. multiple times before the touch is registered. The problem persists until I reboot the device.
I haven't rooted yet or otherwise modded it at all, but maybe I have a poorly optimized app running? Haven't tried to capture a logcat yet either (and frankly wouldn't know what I was looking at).
Has anyone else experienced something like this?
Thanks!

Looks like mine is suffering something similar to the problems discussed in this thread:
http://forum.xda-developers.com/showthread.php?t=1779652
I also have this issue. Was able to reproduce with multi touch tester apps. When I cross axis the touch points freak out. I think it's a grounding issue. If I touch the headphone jack or have headphones in the issue goes away. Called in a RMA request yesterday. Hope this issue isn't present in the next device.

Hi,
I've started to notice that my spen doesn't seem to be working anymore. I never want first day that it is very difficult to use the pen for taking notes, drawing, etc. Wasn't dropped or anything like that, it just seems to of degraded over time.
I've tried it on stock market rom and cm9 and having the same problem. When I checked the pen on stock rom, by showing pen location on screen, it shows it (both when touching and above the screen), so it is being sensed.
Finger touch works fine so I think the digitizer works well. I also have a screen protector on, but I've tried taking it off and having the same issue.
Does anyone have the same problem?
Also, is there a way of increasing the sensitivity to the pen to see if that improves the problem.
Cheers,

I guess it must be due to minir wear-n-tear . You may try to OPEN and RESET at respective parts of your SPen.
I had posted a thread titled "Anatomy of SPen" on this forum, which might help you understand how to open and reset it.
Does anyone have issues with the touchscreen skipping every once in a while? Occasionally, there is an area on the lower half of the screen that seems to be insensitive, but if you start touching around it, it goes back to normal.
I've discussed this with some fellow Z1 owners and it appears to be a relatively common issue. There is some discussion that it may be due to overheating or a software issue.
Anyone else have this problem?
Had this once while my device overheated hard(~47-48°).
Not sure if I have to be concerned about that, because otherwise it works fine.

Same here

At first I thought it was an issue with crappy screen protectors. The Z1 already has a anti-crack film on the screen so I thought that adding a poorly made screen protector would create too much distance from my touch to the sensor. However, I've tried replacing the screen protector and also asked other people with varying brands of screen protectors and it seems that the issue still persists.
The issue seems to occur most often on the password screen for me (which is particularly annoying).
I've had it too, lower half of screen does not register slides on login screen for a brief moment.. No overheat!

No overheat here 2 but with the same issue.
Also the last days i think that all the screen sometimes is more insensitive than usual.I have to touch 2-3 times to do what i want.
I think that is a hardware issue.
Have it sometimes as well sadly! Can't figure out when exactly it's happening though..
I find it very annoying when I'm scrolling and at the bottom part of the screen, the scrolling becomes a click, which brings me to a place I did not intend to go to. Hope it's software, but can't imagine that.
Happens to me as well, regardless of device temperature. Based on the seemingly random nature of the issue, it should be a simple fix via software update. A similar bug persisted on the 2013 Nexus 7 devices when you laid them flat on a surface.

Same problem here!!!
I think is a hardware issue. When you touch the alu frame the phone works fine. If the phone is on the table or in a cover the issue are immediately there.
Sorry for my bad english. Hope you understand
I noticed some small things and thought it was me but I guess this makes sense.
Could be worse, my previous Note 3 had multitouch issues and had problems register several fingers :silly:
Considering how common the issue appears to be, I find it hard to believe that this is a hardware issue.
I also don't believe it's related to overheating since it seems to happen even when I haven't used the phone at all for a long time.
It feels like a software issue to me since the issue sends to go away if you touch another section of your screen

When you touch the alu frame the issue is not there. Only when you use phone without touching the frame.
Must be some kind of hardware issue...

I am having the exact same issue. The weird thing is, is that it doesn't always fail to register my finger. I've gone a few days without it, then suddenly it's back again. Also in the Xperia Diagnostics app I could then see the phone failing to register a proper line, then 20 seconds later it's gone. Weird thing indeed.

Yes, I have it as well.. First of all though, to reply to a lot of people on this thread, it happens regardless of "flat surface, touching the frame, overheating", or anything else. It seems to be completely random with me. Sometimes everything is perfect, then it goes nuts for no apparent reason whatsoever. I'm almost sure it's a software issue, and hope sony will address this issue soon!
it also happens sometimes to me.
the only thing that helps is to touch the ground of the ac power socket. it seems like the screen needs much more potential difference between the pointer and the screen itself and after a while of using it the pointer (you and your fingers) are more loaded.
thats my theory to it.

Unfortunately, unlike the rooting camera bug, it doesn't sound like Sony has even acknowledge it at all.
Exactly this.

I often have to attempt inputting my password multiple times before I can finally get it right. I have since switched to PIN unlock. Really wish there was some sort of response from Sony.
I'd you're using pie then stop using it and retry the affected area. I had this issues because of the activation area causing certain keys on the keyboard to become non responsive.
