Has anyone else experienced their cursor randomly moving around while trying to type or pages scrolling while they're trying to read? My G2 has been doing this fairly frequently and I can send it back but I'm somewhat afraid to since mine does not have the hinge issue and (so far) has pretty damn good battery life. I don't want to just swap one problem for two more
It happened to me once, but I have yet to see it happen again. Strange though.

Mine is rediculous. Can hardly type. I also don't have the hinge problem, but the trackpad is all over the place.

You have the Desire Z?
Mine does the same thing with the cursor. Makes it very difficult to type a lot of the time. The only thing I can think of is maybe it's a lighting condition... maybe light reflects on the trackpad a certain way that makes it think your finger has moved over it.
I hope there's a way to fix it!
Im curious, are you folks charging when youre having these issues? i had the problem temporarily when i first got the phone so i unplugged the usb cable and havent had it since.
no mystery here guys. it's changing light conditions that are affecting the optical pad. it's the same notion as an optical mouse, if the light doesn't reflect back right it can go all over the place. try finding someplace with a strong overhead light and angling the g2 back and forth and you'll see it activate the pad. that's how it works, light not touch.
Had the same problem, only when charging tho.

I think you are correct...the desk at work has spot where light can come through...when I have my phone laying flat the screen starts to go crazy!!, I was like wtf. It ONLY does it in this spot,no where else...I guess that explains everything

Yes, I'm definitely having this issue. I started a thread a while ago about it. I took a video of it happening, too.
http://forum.xda-developers.com/showthread.php?t=799435
I have track lighting in my apartment, and that's what I think is triggering it. Mine's not as bad as the rest of yours seem to be. It very rarely "goes all over the place" for me. It just highlights random buttons once in a while. I can see how if it activates during typing that it would be a huge pain in the ass.
Stupid optical trackpad... was was wrong with a track ball? I never had a problem with my G1's trackball. Doesn't HTC test these things?
Yup, that explains it. That was my suspicion. Especially since when using Swype (where my hand covers light going to the trackpad) it never does it. It's never been while charging, though - not specifically, at least.
Try holding it towards a light and wave it around. You'll see the cursor jump around. Makes sense. Kind of annoying, but at least it's not a defect.

I actually had to stop using swype because it would happen EVERY time I tried to write in portrait mode
Strange, but it could just be the difference of how we hold our hands or something to that effect. I think the lighting thing does explain it, though.

That was my thought as well, T-Mobile should include a "how to hold" guide in the box
This happens to me whenever I try to use the phone when I'm sitting on the couch with my back to the window. Only place it happens.
Called T-Mobile a few days ago about this and the hinge issue and they immediately issued me a replacement. Probably won't be any better but worth a try right? And if it keeps giving me problems then I'll keep exchanging it until the Nexus Two comes out lol

I've noticed that on my NS, I don't have to actually touch the screen to tap keys. I can keep my finger slightly hovering over the glass and it still recognizes my input. Sometimes it actually causes me to mistype at a higher rate than other phones.
Are you guys seeing this too?

Glad to see I'm not the only one who's experienced this....I thought I was going crazy. It's sporadic at best, but when it happens it is annoying. I can't say for sure what causes it, but I'd love to hear other people's opinions.
I've been getting this as well.
same here. Guess they have the capacitance set a bit too high.....
yup, me too. infact. my home button gets phatom long pressed and the light is off on it...have to power it off/ turn the screen off and on muliple times. that insanity has occured about 4 times thought.
Thanks for the replies. I went back into Best Buy and tried their demo phone. So either it's supposed to be this way or they messed up a whole batch of phones. I wish I could remember whether the vibrant did this or not, but it's not standing out.
Sometimes touchscreen nonresponsive too. This is not relating to partial outer border touching either.

I believe Engadget did mention did this during their review @ http://www.engadget.com/2010/12/10/nexus-s-review/.
Their exact quote: "One other thing of note -- we noticed a few missed or latent presses on the touchscreen which occasionally led to stuttery behavior or an opened item that we didn't mean to tap. It's hard to say if this was a software or hardware issue (and we know that sometimes Android devices can be particularly finicky when syncing). It wasn't a deal-breaker by any means, but we saw the issue rear its head a handful of times, and felt it was worth mentioning."
it's nothing ,, the Samsung galaxy S does that too D:
that happens due to the static on your finger.
Hi
I opened a thread (http://forum.xda-developers.com/showthread.php?t=879872) because I definitely have a problem on the back capacitive button, just wondering how many people are affected?
In fact I have seen this in four devices now, it looks that there is a batch of defective Nexus S phones out there affected by this problem?
It's normal. My Nexus One is like that too. It's magic.
So, it is normal to have un-responsive back button after some times?
Damn ... this is bad. I hope I can cope with it. I really hate hardware problem.
And still could not understand why Google cannot fix it.
Last time from HTC ...
And now from Samsung ...

There's a thread for the back button, that's a real issue. Some people have the Back button issue, some the Home button issue. Both of those buttons are on the outer edge of the phone, so something may be messed up when the phone was being assembled.
Hi,
I've got some weird problems with my N1. I searched around but couldn't find the solution.
I've tried CM7 stable 7.0.3 and Nighties 87 builds, and this problem happens to both.
1. When I'm running an app, such as "plants vs zombies", or typing with keyboard, when I touch a spot, it thinks I touch another spot. For example, when I touch key "D", it may give me a "space". When I try to place a plant on the left side, it puts it on the right side.
2. When I'm watching videos with MoboPlayer, the screen is locked sometimes (maybe this is a setting that I don't know, how do I turn this feature off?). When I press the "menu" button, it was supposed to unlock the screen, but it actually unlocks and locks back and forth continuely, and the phone keeps vibrating.
All the problems will be gone if I just lock the phone and unlock again. However, it will come back after a while.
Please help and thank you very much!

Just turn off the screen then back on, it clears this bug and only takes a second.
All nexus ones have this issue.
I traveled from Singapore to the States for about 2 weeks in May and I suddenly had this issue too. I never had it for the 16 months I owned it back here in Singapore. And when I got back after my 2 weeks trip, the problem never occurred at all again.
I'm guessing that it has to do with either the temperature or humidity levels.

I have similar problems as mentioned irregularly, but sometimes switching the screen off and on doesn't fix it at all. It's not very humid where I live (except when it's raining). Has anyone else considered replacing the digitizer (the touchscreen panel) of the phone, and if this would fix the problem?

I sent my N1 back to HTC for warranty repair because of this issue. They did something and sent it back saying all good now. The issue occurs less frequently now but it is there.
I suspect there is something in the trackball area that generates EMF of certain qualities (frequency?) and it interferes with the screen circuitry due to poor shielding and close proximiy.

this is definitely a design flaw of N1, the touchscreen controller chip just SUCKS
I really cannot figure out this issue I'm having. Basically, I have the black rubberish/flexible case that T-Mobile sells. Once in a while, while using the touch keyboard ( stock gingerbread, I'm using cm7.) A couple letters become unresponsive. Most work, but others will not.
Weird thing is, when this happens and I take the case off, all goes back to normal. Maybe I'm missing something here, but how could the case cause this?

Maybe the case is applying pressure to the device and for some reason making the screen less responsive. I have this with my TPU-S Curve case and the one with the kickstand on it.
I actually believe that is a CM7 bug. I have experienced the same problem on recent nightlies. Some keys on the keyboard will go unresponsive, while others will work. Occasionally the entire keyboard locks up. Once, the keyboard worked but the image of the keyboard didn't show up (tapping in random spots on a webpage resulted in text being typed, lol).

Everyone experiences that in any rom, even stock, once in a while. The point is, some letters work, some dont. The ones that dont work usually are not even close to each other. and EVERY time it happens, I take off the case and it goes back to normal.
As for the theory that the case was causing pressure, the chances of that are slim for two reasons:
1. It hardly even reaches over the glass. at most, a couple millimeters. http://www.t-mobile.com/shop/AddOns...48e2-bb7a-0e5d354aefa7&inCart=True&catCode=21
2. Being a gel skin, it doesn't really cause pressure to the phone at all. (I could be wrong here, it just seems unlikely.)
This just baffles me because I KNOW its the case causing it but I can't begin to comprehend why.

Just for kicks I tried applying pressure to the edges of the screen using the gel case while typing. I also wiggled the phone around in the case so I could test all positions, all while typing away and nothing could reproduce the unresponsiveness.

Yeah that's true and I like the case to protect it when it falls.
Perhaps the gel case is electrically conductive? I noticed one day I was caught in the rain and some raindrops fell on my touchscreen, which caused random things to be selected until I wiped the water off.
It actually might not be the case... The myTouch 4G's screen has random spots that die temporarily for no reason, and keeping away from the screen or locking and unlocking it can revive the spots. It's not the case at all, probably just the time it takes you to take off the case that the spots revive and convince you that it's the case. Try letting it sit for about 20 seconds when the screen dies and see what happens.

When at home I use the phone without the case quite regularly. I've never had this issue when the case isn't on.
In fact, I can usually (Without taking the case off) go back to the homescreen and do stuff, all spots being responsive, while the keyboard is acting funky. The keyboard itself has the issue but nothing else, even when using the same touchscreen spots.
It's such an odd correlation, the keyboard software itself and the case. Yet there has to be something that one does to the other.
Also, just to make this clear - this ONLY happens to the keyboard. If that theory was correct I would experience this in any app
I noticed this also when I first bought my phone, bought the rubber case the same day. after a couple of months, the letters towards the end of the keyboard would become less responsive and I had no idea why. took the case off and it went away. so I ditched the rubber case and got a TPU, never had the problem since then. I think over time the rubber case gets a bit stretchier and bigger, causing you to have to sort of roll your finger around/over the case to press the keyboard buttons on the end(unless in landscape mode)
You know I've always had this problem, and I thought I was the lone soul that had this retarded hardware (maybe software?) issue. I was on Royal Ginger 2.1 and never had this problem. But then subsequently left RG and started using ROM's like Virtual Fusion, MIUI, Virtual Unity, CM7 RC1 and other CM7 nightlies and all of them I've had the problem where some of my keys would just stop working, most noticeably the "delete" key. Other keys like the letters "P" and other vowels would cause the same problem as well. So I figured it's just another list to add on to the plethora of hardware defects that plagues this phone. I've used several KB's as well such as Flex T9, SwiftKey X, SmartKeyboard Pro and even the stock GB keyboard and problem still persisted in all of them.
So I thought what the hell might as well flash Royal Ginger 2.1 to see if the problem is still there and after 2 days I have yet to encounter it! So now I'm baffled... I was for sure that it was hardware related but now I don't get why it's not happening ONLY to Royal Ginger...
I have had the same case on my phone, it's a TPU case. I know it is not the cases' fault as it's always on my phone even now when I'm on RG where I have yet to experience that problem even once.
So I'm pretty much dumbfounded...
I don't think it's the case. I thought it was a ROM thing... agreeing with mackster on this... haven't had a problem while on RoyalGinger 2.1, but have encountered it on CM7 RC1, MIUI & Virtuous Unity...

Does anyone else have their screen respond without touching it?
I've noticed this in go sms. On the conversation list, the last one on the screen is sometimes pressed without me touching it. I will press back and it just goes back into it.
I recently noticed in web browsing too where the screen would refresh on its own. I clued in that the refresh button is on the bottom of the screen.
Seems like the bottom maybe 2 cm of the screen sometimes responds on its own.
Is there any app that I can see where the screen is being pressed?

I dont think there was any moisture on that part of the screen either
Yep, but not on this phone yet...
I say not yet because it's happened to me on almost every one of my touch screen phones. It seems to happen to me when the air is dry and I bet it has to do with there being more static electricity around. On those days when you're shocking everything you touch, those are the days when my phones seem to act up. It happened on my G1, my vibrant, Droid1, Droidx, and two of my bionics. All of the problems went away although on my 1st bionic it was really bad and almost completely unusable. The next day it was back to normal. Maybe it's just gremlins.
answer:
it happens if/when you use a DIFFERENT charger for the phone. you should be using the charger that comes with the phone. If you use a different charger (from a G1 or from a razr or something), then the screen tends to mess up, even when off the charger.

Is yours also happening towards the bottom of the screen?
For those of you with this problem, try pulling the battery out for a minute or two and also try touching something metal if you can. You know to discharge any static built up. (Worth a shot right) When I had this problem on my Sensation everyone was reporting that it was the charger they were using. I don't know if that was correct because the problem went away even though I was still using two different chargers. One charger was for the GNEX (same as GS3) and the other was the HTC charger. I really think it has to do with static electricity build up. If you think about the way these digitizers work it really makes sense. It seems to happen to me during spring time when it's dry and windy.

That is a good theory, but why would the static shock only be hitting the bottom part of the screen?
i don't know why. but i'm sure it's the charger. this happened back in the G1 days when android first came out. i did so many "experiments" with different chargers to figure out what was causing the screen to be all glitched like this. found out it was the charger. same thing happened with my vibrant, and same thing happened with my sisters sgs2.
Multitouch Visible Test
With that app, 1-finger touch is alright, no issues.2 Fingers seems alright too. Adding up to 4 fingers seems to be alright and moving them around the screen.
Sometimes with 5 fingers though, they'll all show on the program, and then immediately vanish. If I keep moving my fingers across the screen, they'll pop in and out, but won't actually stay on screen and follow. But this only happens sometimes. Other times, 5-finger input works fine.
My other camera is dead at the moment and I have to run and get batteries for it tomorrow, so I can't actually upload video of what I mean. I was hoping to get some input from other people about how their multi-touch seems to be with that app. Not entirely sure if this is just a rare defect, widespread, or working as intended maybe (not entirely sure if there's anything saying how much multi-touch this screen is; figured it was 10 though)
Some things to try:
- Use 1 finger, drag it all over the screen
- Keep adding fingers 1 by one after dragging them across the screen (add finger, drag it around, add next finger, etc.)
- Don't touch the screen for about 3 seconds, then just have all 5 fingers come in-contact with the screen, and keep them in one spot (on mine most of the time, the points appear then immediately vanish)
Could it just be the app your using?

Called up Google and it doesn't seem to be widespread (or at least the person didn't say it was), and I could get a replacement under warranty. I don't have the funds to put on hold currently so it'll have to wait if I do decide to do it.
Although I wonder if I really should, I mean I highly doubt I'm going to do anything requiring more then 2 fingers on the screen at any point (nor can I really think of anything), and aside from multitouch, everything else seems great. No dead pixels, back doesn't flex, screen is alright quality-wise.
Would be nice if some other people can try out multitouch though just to see if it really might be widespread or not though. The thing is though, it works fine sometimes, and other times it doesn't. Perhaps software might fix it in time, but I don't know. I thought I heard of the Nexus 7 having a similar issue, but I can't recall...

It seems to do the same even with the "Show touches" option enabled in Developer options (tried it on an empty homescreen).
Bump
Anyone? It only takes a minute or two at the most to test this... and the apps available to do so are free and light.
Doing the tests you described never caused anything on my tablet. But if I put my hand down on the tablet flat then put my five fingers on I get your issue. Then wait three seconds and try again and everything is fine till I put my palm back on.
Might be a badly configured palm detection algorithme? Op, do you have fat fingers? Sorry if that sounds rude

Lol, hmm, na I don't think I have fat fingers
How about fruit ninja, does that work properly? It's true that if show touches doesn't work, it's not a good sign. Unless it's a system firmware bug
1 and 2 fingers seems to work great in Fruit Ninja; 3+ randomly works or doesn't work, and when it does work it seems to cut-out at some point and then just show slashes delayed from where my finger is currently
Any idea if its hardware or software related? I have the same issue with my N10 and don't know if I should get a replacement or not.
Got mine today, same issue. Actually, that too bad since everything works fine, and i only got a minimal light bleed. I hope my replacement won't be worst regarding light bleed :/
Same issue on mine. Considering a replacement now with this and wakeup lag + battery issue (indicator not updating % at all!?)
Don't know if I wasn't lucky or just poor QA.
I'm pretty sure it is a software thing because when the problem occurs and I tab on the multitasking button twice (so it shows the multitasking menu and switches back to the app) the touchscreen acts normal again until I put more than three fingers on screen.
But if its a software problem, shouldn't it happen to on every N10 running the same Android version?
I have the same issue. If I slowly add one touch at a time, it usually works. But if I touch down 3+ fingers at once it gets very confused and bounces between zero and N touches. I have a Galaxy Tab 10.1 (first generation) and multitouch seems to work much better on it than the Nexus10. However, I did notice that the Nexus10 is better at distinguishing 2 very close touches than the GTab. On the Nexus10 I can have my fingers as close as 1/2 inch or so before the touches merge. On the GTab it is more like 3/4".
Hmm, kind of interesting to see that others are also having a similar issue.
I noticed that when I tried a custom ROM (latest Kernel sources + 4.2.1), the multitouch seemed to work, slightly better (the issue still occurs, just maybe not as much). Not too sure if it was placebo or what though.
I called the support and will replace mine with a new one. It might be just a software issue thats solved with an update but I don't want to risk it.
just got my replacement today, same issue (and also worst light bleed ). Third replacement on this way...
