Sometimes, I'll place the handset down on a table or whatever, and completely of it's own accord, the screen will scroll right to the second page. Then a couple seconds later, it'll scroll right again to the third, and fourth. I'll pick it up and swipe back to the home screen and put it back down, and it'll do the same thing again. Basically.... wtf?
Sometimes it does it in menus aswell, scrolling down lists one by one every few seconds when the thing isn't even in my hands.
Has anyone else experienced this? I've had a couple of replacement handsets and it's done it on all of them!

It has happened to mine, intermittently. I was hoping that it was just a little piece of grit under the trackball and that it would stop, but now you've got me worried that it is a common fault. Mine is an unlocked white in the UK, bought from Devicewire and delivered around 10 days ago...
Yup, I can comfirm it has happened to me with 3 white sim free Heros. It can happen when the device is completely undisturbed so i'm assuming it's some weird software glitch.
I can't even identify what causes it, to recreate the conditions. Seems totally random.

Hopefully a (rapid) firmware upgrade will sort it...
Could it be something on the touch screen?
I think I have seen this too! Do we all have screen protectors on? I do on my Hero....
It seems to me like the people widget caused me some issues. I have removed it and the device is faster and this bug hasn't appeared for me at all since.

Screen protector, yes. And the People widget (which I find very useful!)
Speaking about really weird things going on with the Hero. I can contribute with some funky stuff too:
When having my Hero near/under my mousecable the mousepointer (on the monitor) gets its own life. It starts moving randomly and begins to scroll the pages up and down in my browser WITHOUT me touching anything. I do have a cable connected mouse (USB). The phone has wifi, GPS and Network activated. I have not yet tested what happens with those turned off though.
Haha this is getting interesting. I noticed some mousepointer jitter when I was using the PC at work today, with my Hero nearby. I'll investigate more today.
Mine doesn't have a screen protector, but I do use the people widget on my second page. I'll remove it and see if it makes a difference to the spontaneous scrolling.
I just got my white unlocked hero 3 days ago and I just noticed this problem for the first time. The home screen would move over 1 or 2 screens without me even doing anything. Im wondering if it was major lag from previous movements I made. Im sure this is a software bug, does anyone know if HTC releases software updates for their android devices? I just switched from an iphone and hope they would release updates and fixes like apple did when something was wrong with a software release.
This phone is what... a week since launch day? We are early adopters and will find bugs. There'll be an update soon I'm pretty sure.
I think there is some interference with Wifi/Other radio and the Hero screen.
When i put mine on my desk next to my PC i cannot press all buttons on the touch screen but the wheel and hardware keys still work. When i move it 1m away from my PC this behavior is gone.
This problem happened to me when I had wet hands. All I did was wipe the hero dry and it worked fine again.

This is due to the phones aggressively high SAR value (it's really really high). I would think twice before putting this phone in your pant pockets if you ever want to have chidren

Wow, really? I already have 2 so going to keep this in my pocket from now on!!!
Aaaaaaaand HTC didn't bother fixing this in the new rom. The T9 keyboard input bug and huge lag are also unchanged.
I can confirm that this odd bug still lurks around in the official 2.73.405.5 build.
It has been suggested that it migh be due to dirt inside the trackbal housing but then why would the homescreen suddenly scroll on its own without being touched? Maybe a sensor glitch? I don't know what solution HTC are using to read the movements of the trackball though... one thing is for sure; it's not a good one....
I'm 100% sure now it's not a hardware issue. It's happened on multiple Heros I've used, not long out the box either. The only thing I've noticed that indicates any kind of pattern to the apparent randomness is that it gets a lot worse when there's a lot of mobile data transfer going on. One time I physically couldn't get it to stay on the homescreen long enough to click an icon.
Just pitching in, exact same problem here. Very strange that everyone gets it to the right :/
Just notice on mine too, some automovement in menu and home
Upgraded yesterday to new firmware (modaco)
Could be an increase of trackball sensibili? I see a settings to tweak it on blackberry device...on android?
Since 2 weeks the bottom 1.5cm of my touchscreen doesn't work
anymore.
I assume this isn't software related? So i will take it back to the shop for
reparation.
Because i have a custom rom installed, will this be a problem for my garantuee?
Or do i have to install back the official rom? And wich one?
Kind Regards,
Dieter
Same problem here...
After upgrade to 2.1 (VillainRom 3.4) the touch screen doesn't work as before. It seem that the bottom of the screen has some problems, the keyboard is less receptive...
Jef
I to had it after an upgrade to 2.1
Dont think its rom related...
I am on the official update from late last year (1.6? 1.5?)
Its been fine until about feb/march this year
Asked the tmobile store how long itd take to send it in. They reckon 2 weeks. wtf?
And they didnt have any loan phones.
Why does it take forever to get anything done in the uk?
Anyway... I reckon its the hardware. Must be a loose connection inside between the touchscreen or something.
Sometimes the bottom of the screen is not working... sometimes wherever I touch the screen it thinks im touching the bottom but on the same coordinate on the x axis... sometimes it just goes completely nuts as if I am sliding my finger side by side along the bottom of the screen (when I am not even touching the phone). Sometimes switching it off and on helps... sometimes it doesnt...
Initially it was only happening occasionally... but it gets worse... now I can expect it to happen every third time I try and use the phone for anything.
Same here , it's annoying. It was never there for 6 months but since Feb 2010 , i've been having this touch screen problems.
Since the upgrades for 2.1 started coming in , right after modaco custom rom 3.0 .
i had this problem. bottom of the screen was unresponsive unless i put my full thumb on it (not so good for typing) and sometimes it thought i was only touching the bottom. paid $115 to get the screen replaced. works a charm now.
We have seen multiple videos of the screen grounding issue and there are many that say theirs does not have this problem. I have two evo's and they both have this issue. I would request those who are not haveing this issue to please post a video of their phone's touch screen working while not grounded. It is not that I think anyone is lying, I just wonder if maybe the issue is not being tested correctly. I just want to see someone's that does not have this issue so I can be confident that if I return mine I have a chance of receiving one with out this problem. So please anyone that does not havethis issue show video of the phone on a pillow or bed or multiple ungrounded surfaces with the phone not plugged in to anything and demonstrate the drawing app and also the pull down notification so I can see one that works. Thanks in advance!
It's not consistent, I hadn't noticed it until after I found out...I noticed a screen tap wasn't registered when I clearly pressed.
If you look at the demo images, it shows it does work, but doesn't always work...it's not consistent like it should be.
Yes I know that it is inconsistant... that is the issue. What I am asking for is to see someone's that consistently works while not grounded. I want to see if there is even one evo out there that has a touch screen that works as it should while not grounded. I believe that possibly those that say they dont have this screen issue may not understand what we are saying or are testing it differently.
mines having the issue hold it in my hand its fine lay it on the desk it messes up
I had never noticed this until I did as you suggested and use it on my pillow and sure enough I have the same issue. Not sure if it matters or not to me yet since I only notice it during this testing and not with every day use. Guess I will have to think about it!
Just tried this out on a pillow and for me it is just the top 1/3 of the screen that goes unresponsive. Tried it with the marketplace and i could scroll just fine through the list of apps at the bottom but from the Apps, Games, Downloads Tabs up, the screen is unresponsive.

I returned my first Evo because the screen in the portrait notification bar area was dead to touch.
My new unit has no issues whether lying flat on a desk or on a bed or pillow.
Mine is going back to Sprint a new one issued, just waiting for them to get the new batch in.
I called them yesterday about it and let them know it is being returned for a new one.

Do you have a video of this?
Up until just now I thought mine was perfectly fine but I just tried setting it on a pillow and doing it and lo and behold, it's a little glitchy at the top 3rd of the screen. It's perfectly fine laying flat on a disk or stack of papers though.
This doesn't seem like such an issue to me though. Not as much as the 30fps issue. When am I ever going to be lying my phone on a pillow using it? I always hold it in my hand anyway.
If the original poster wants to keep a tally: I have the problem and have the 1st hardware revision. I also confirm grounding the screen itself did no fix the issue (since I have the invisible shield). However, the problem was immediately resolved when I grounded the battery/phone negative terminal by running a wire from it to my bare finger. Touching the screen with my other hand/finger showed the issue had disappeared.
I posted a video on YouTube, but xda won't let me post links since I am unverified.
So I am coming to the conclusion that this grounding issue effects all evo's, seeing that not one person can produce a video of it working otherwise.
My evo works fine no matter what its on. I post a video later today.

Works
Mine works. I haven't seen an issue on any surface or lack of surface. The four other's I know who have the phone haven't had this issue either.
Mine works too, no grounding issues here. Why no video? Just don't feel the need to prove anything to you.
My EVO doesn't have this problem at all. I put it on a stryofoam plate and it was slightly less responsive, but still worked on all parts of the screen.
Mine doesn't have the screen grounding issues, but my colleague's does. I used the phones side by side and I see how the top 1/3 of his screen doesn't respond when laying flat. Mine works perfectly. Unfortunately I have bad light leakage above the buttons where his doesn't.

No video necessary. Just do what I outlay in my post:

Takes only a few minutes and you can see immediately and with real accuracy whether or not your phone is working properly.

I am asking for video simply to see if there are any phones out their that do not have this issue. If u don't want to help a fellow evo enthusiast out fine, but seeing how I have not seen a single video of the phone on an ungrounded surface which does not suffer from this issue j doubt you are testing yours the same way if it is not giving you the same result. That
Is why a video would be helpful. Because if yours indeed does not suffer from the problem then that means that there is chance that if I returned mine that I could get a working model. So if you want to help fellow forum members out... post a video.

Anyone else having a weird, intermittent issue with the touch screen seemingly not working right
IE: I try to scroll and instead it makes a tap where my finger lands. Unlocking the screen doesn't work 50% of the time because the lockscreen will just lag out and I have to sleep/re-wake the device
This happens on stock and after i rooted to tiamats rom

I haven't experienced or heard of this before, at least as you're explaining it.
Is this accompanied by screen dimming? Did this start after the update to HC3.2?

Your device may not be grounded. It's a common problem with touch screen devices. Does this happen when you're holding the device in your hands?

I really don't know, let me do some testing and see what circumstances it is replicated under.
How would grounding be determined? Its not charging...
I do have it in a silicon/rubber case. Would that be a problem?
Just for the sake of satisfying my curiosity - if you are experiencing this issue while your Xoom is docked - try placing your fingers on the back of your Xoom and typing with your thumbs.
I am trying to resolve a similar issue that I only encounter while my Xoom is docked at one place in the world - my work. Nowhere else does it do this.
I have installed a power conditioner, with no effect. It happens whenever the power is plugged into the dock. If I use an external power supply it goes away (batteries). I did switch off the florescent lighting and it is better, so it may be EM related. especially since it is a *capacitive* screen.
I have also read of people with other capacitive touch screen devices have the same issue when it is not held in their hands.
Let me know either way.
Thanks,
Frans

I have seen issue on gtab where some roms/kernel where having issue with screen calibration, there was a calibration files that could be created in the root with the name calibration.ini and upon reboot it was fixed, I do not know if this is valid for a xoom tho...
with a few rom I had NO issue whatsoever and never reused the calibration...

Well you bring an interesting point. The device was in my hands but I was not actually touching it... It had a rubber sleeve on it.
I since got the Motorola hard case which has some areas exposed and I also disabled the lock screen, and I have not been able to replicate the problem at all.
The device was docked at one point, charging, and the problem showed up aagin (recalling from memory). The fix was to power off the screen and re-wake the device. This did involve touching it, so...maybe its an electrical thing?

I had this problem with the stock 3.2 ROM. I haven't done any calibration, and don't think I need to: it works perfectly majority of the time.
I'll reenable the lockscreen and try to replicate it again.
Okay I think I'm onto the problem
I opened the case just now, still lock screen disabled, pressed just the power button and the touchscreen was acting up again.. couldn't slide to scroll, but could tap/point only
I then put my thumb on the side, as if naturally holding it without a case, and it started working normally again without any kind of power cycle.
Thoughts?
Have you dropped or jarred your Xoom a lot? Look for threads I started in this forum, I have one that explains this issue and includes a fix. My Xoom is still working flawlessly. I'd link it but pre-calculus is about to start.

I bought the XOOM second hand from someone who claimed they hardly used it. Right now sitting infront of me, the bottom right, on the back edge, there is a small pressured crease as if it was dropped (looks like the corner of my phone when i dropped it on tile).
I personally have not dropepd it, but I throw this thing onto my bed all the time, it fell out of the dock onto my hard desk once, so yeah its been knocked around.
Will doing that mod void the warranty?
I found no warranty stickers or screws when I disassembled it. The back cover is made to slide down so that Moto can do the 4G upgrade, so I doubt they want to be fooling with that type of thing anyways. I can't say for certain that sticking a piece of foam in the back of your Xoom won't void the warranty, but I can say that it fixes the issue(which also could be covered by warranty if you can get someone to believe you've got the issue, I however could not, so I had to take it upon myself).
Alright
I just ran into the problem again playing a game.. seemed like the right half of my screen just stopped working intermittently. Kept playing and it returned to normal.
I may pop it open and try the foam thing. I'm pretty good with disassembling laptops.. I can't see this being much harder.
I have a UK Advent Vega Tetra Note 7 (the Currys /PC World version) with a slide cover. Lately the touchscreen has been exhibiting a few intermittent problems. The most annoying is that when I hit a soft key or type a letter, the screen registers multiple touches. This is extremely frustrating when I hit the back button, only to close the entire application.
The pinch and zoom sometimes plays up to. I thought that might be related to the already-identified issue over the black area to the sides of the screen being touch sensitive when they really should not be. It means that your palm often inadvertently acts as a second finger when scrolling, and zooms the screen. However the problem seems deeper, as it can happen even when being careful not to touch the bezel. And if you hold the black area off to the side of the screen, it brings up a menu.
When browsing, occasionally the touch and hold works a bit randomly, for example, when you hold a link that you want to bring up in a new tab.
I have factory reset the tablet and the problem disappears, only to reappear later. And it isn't constant either - it comes and goes.
I wonder if the issue has something to do with the magnetic slide case? Or do users without the case also experience problems? It really is a pity, as this is a great tablet otherwise.
I've had issues similar. After going back to 4.3 they seemed to go away (battery life was better too). Now back on 4.4.2 and OTA 2.3 the problems are there again. It must be a software issue, hopefully it'll be fixed along with the battery life issues.
Roll on 4.5 and let's hope nvidia give us it.

How did you downgrade? Is it just a case of a factory reset, then declining any upgrades?

Look here for an Advent guide to reflashing the 4.3 ROM:
http://www.adventcomputers.co.uk/product-download-select/296
You can ignore the updates afterwards. By no means though is 4.3 perfect, there is problems with the GPS and various other things that have been fixed in the latest versions.
Personally I found the latest to be best overall - Minus the battery life issues and some minor stylus/touchscreen issues.
Thank you BuToNz. I developed touchscreen problems when using the stylus after updating to 4.4.2, sensitivity was lost in an area the size of a large coin, if it registered anything in this zone it was just a messed up line. I downgraded as per the link details to 4.3 and the touchscreen with stylus is fine again.. Left feedback with Nvidia, hopefully they can repair this.

tegra note touch faulty
me 2 facing the same problem pls help..
There is a known issue that has existed since the tablet was launched where sometimes if you wake the screen by opening the cover, the touchscreen can become erratic or unresponsive. If you do a quick sleep/wake with the power button, it usually fixes it. Why Nvidia hasn't been able to fix this after a year is baffling and part of why I held off on getting a Shield Tab (among other reasons).

This has been consistent with mine and I can live with it, however recently randomly after a day or two of use, if I turn off the tab with the power button and have it charging, when I go to use it again after a random time, I get a completely unresponsive touchscreen after powering it back up with the button. No response from the screen at all. Buttons work fine, and a hard power down fixes the issue just fine, but no amount of play with either the power button or screen cover or even stylus fixes the non responsive screen. Very strange.
Still love every bit of this tab, but do hope for a Android 5.0 update soon for both it and my Shield Portable.
