Hello,
I've been having touch screen issues lately, since i rooted and switched to CM 6.1 a couple of weeks ago. The screen will work perfectly for a little while, but will inevitably stop responding. I'm using launcherpro, though i don't believe that's the issue- it happens regardless of which launcher I'm running (I've tried others and experienced the same issue. The optical scroll pad will still "sort of" work- better than the screen (which will respond to the occasional touch after the problem begins, but barely does). If I reboot, the problem will usually go away for a while again, but will recur. I wind up needing to fix the issue once or twice a day. I don't think it's a hardware problem because the reset fixes it, so I assume it is then software. Also, i don't remember having this problem with the stock rom. Has anyone else experienced this, or does anyone have any ideas?
Thanks!
Dunno how useful this will be, but have you tried reflashing CM?

Same problem here. But I've noticed sometimes if I'm using the phone not in my hand (on car dock or just on table) this problem seems to happen more...but when I hold it in my palm then works fine.
But sometimes it just becomes unresponsive. Am running virtous's rom on my g2. But I can remember having the same issue when running cm on my g1 days too. Reboot always fixed it, just gets annoying.
Anyone have fixes to this? Thanks!!

I personally use GV 7 or sparksmod and. Never had a problem, these are the best roms I think for this phone.

Been having this exact problem for weeks now. And I believe it is a hardware problem, probably some sort of short in one of the ribbon cables or the digitizer itself. Occasionally, actually 85% of the time I'd try to open an apparently and the phone would act if I held my finger down and then the apparently icon gets selected...very annoying cus it happens over and over a couple times, all I can do is keep trying until it does what its supposed to. Also with the on screen keyboard when I'm texting it'll act like I'm holding down on one of the letters and keeps bringing up the special characters to that letter...or ill tap delete to delete a spelling error and it'll end up holding it down and deleting my whole damn text and I can't stop it.
At first when this first started happening I could simply tap the screen and it would stop the crap it was doing and work fine. As time went on I noticed I kept having to hit it harder and harder for it to correct it. Wellllll guess what? Last night it was acting up horribly and I slammed my closed hand against it while it was on the desk and it cracked the LCD screen and now the phone is completely useless, even though the outer touchscreen is perfectly fine.
The restarting of the phone also usually fixed it for me as well but only for a few minutes.. which also makes me think its a short because after the phone is turned off whatever part is shorting out, that circuit is closed and just takes time until you press on the screen in whatever spot to cause the two parts to touch and create the short all over again.
Anyways that's my story...just don't get angry and slam down on the screen lol. This is my 2nd G2 and I'm tired of it, probably just going to get a nexus s or just go back to the nexus one, atleast it was reliable.

if you open the battery cover u can see that there are connectors that closes the whole circuit, so when u are holding the phone the back cover works like a grounding area that makes the screen responce to your touch. Acapacitive screen works like this: when you touch in any area on the screen, you simply are breaking the electrical field that the screen has, the screen "feels" where u break it and tells the operating system.
the electrical field depends on the human body a bit to make the circuit complete, so when u touch the metal parts of the phone, the screen works like it is designed.

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?
Recently (starting hours ago) When i try to text and use the physical keyboard it jumps around. It may scroll up the message or go over to send or things like that. I have taken my screen protector off (great, now i buy another one) and wiped it all down but it still does it.
I also reset it a few times.
Anyone else experiencing this?
I am getting the same thing. I think something is conducting on the capacitive screen as when I set the phone down or don't touch it at all, this never happens.
So should i exchange it?
I don't know. Like I said mine seems to do the same thing. I am not sure if it requires exchanging or if my fingers are brushing the side in a way they shouldn't. I'm open for suggestions myself
Hmm no mine just jumps up the text page like it scrolls the chat message up even if nothing is touching the screen.
Same thing here. Used to happen with my old myTouch but it was after a couple months of use. Uncool for it to happen on the G2 just after the 14 days have passed.
It is probably the capacitive pad thats not working right. Its probably detecting heat and scrolling on its own.
Yes get a replacement.
It's the touchpad. Move to a room with different lighting and try again.
I second the touchpad. It messes me up in the terminal by sending special characters.

I did notice it was the light now. Still does it sometimes tho.
Thanks. What do you guys mean by captive ? Heat ?
Mine does this randomly too, and I've also concluded it's the trackpad. One time I went to my home screen while it was doing it and I could watch the selection scrolling from left to right.
Haven't figured out how to fix it, usually if I lock then unlock the phone it works fine.
Mine just started doing this today. I was sitting under the A/C and i noticed whenever i would try to swype during SMS text messaging, it would highlight "Send" in orange or it would highlight and scroll up the text thread. After I moved away from the A/C, it stopped doing this. my trackpad has been fine and I have never had any issues prior to this or even after moving away from the A/C vent.
This trackpad works on heat I would guess or like others have said, possibly electrical ground current which is probably by a grid I would imagine.
Thats kinda bad for you guys. I havent had this problem at all but seems like a trackpad problem. This happen to me on my g1 onces and that was a dirty trackball

i bought my incredible used about a month ago and i noticed that occasionally when im using the optical joystick and im scrolling down sometimes it will just start to scroll up, even after i move my finger away from it. also sometimes it will randomly keep trying to scroll up uncontrollably.
i was thinking that this possibly has to do with my screen protector, is still brand new and has been on the phone since before i even bought it. but my question is if it is worth wasting a perfectly good screen protector to find out if its causing the optical joystick to do this? and i have no idea how to even remove the screen protector because i have been trying to pull it off for a while now and no luck.

The track pad being dirty can cause this, I usually just wipe it with my shirt and it's fine.

It may be a coincidence, but I used to periodically (once or twice a week) have my optical pad start drifting or go out of control. In the month or so I've dropped HTC Sense and been running Cyanogen ROM, it hasn't happened a single time.
This happened to me before and they just sent me a new phone.
Got the new phone and never happens.
I researched a while back and this is somewhat common with the incredible.
The top part of my phone does not respond to touch anymore... it is impossible to bring down the notification bar... and once in a while the whole screen goes unresponsive.. tried factory reset but still the same problem..
am having the same problem since 2 days back
after reading some of the posts i found that the Digitizer For HTC G6 Legend A6363 should be replaced with new one i ordered mine from ebay
ebay.com/sch/i.html?_from=R40&_trksid=p5039.m570.l1313&_nkw=Digitizer+For+HTC+G6+Legend+A6363&_sacat=See-All-Categories
waiting for the item to be delivered
I've also got a touchscreen issue: the area of the notification power widgets is unresponsive... the rest of the screen works fine, but I don't know for how long :/

Do you have widgetlocker, by any chance ?
Or a lockscreen replacement which disable the notification bar during the "slide to unlock" state ?
I didn't know there was such thing as widgetlocker. I use CM7 latest nightly, never seen that thing.
I also facing this problem from last 2 weeks and i also think this is digitizer problem. If anyone else found the solution else changing the digitizer, then please post.
This is beautiful phone but htc added a poor quality things in it, due to which many users facing such problems.
Nah.. I dont think its because of widget locker.. its the digitizer..
well that's a shame, gotta buy a new digitizer on ebay after just over 1 year of use...
I know.. this sucks... Im planning to upgrade though.. Any of u guys have any suggestion?
Depends on your carrier if you want suggestions for an upgrade.
...but that would drive the post off-topic.

I have the same problem. my screen doesnt work anymore because some water got in from the grill above the screen :S
should I try to take apart and dry off or shall I buy a new digitizer directly?
I think it may be a good idea to try disconnecting your digitizer and reconnect it as it just might be helping. I did it on my girlfriends legend and it has been working perfectly ever since. Maybe a good idea to at least try that before buying a new one. So i guess it could be in the connector to? At least this worked for me.
My touch screen dosent work at times. but after rebooting the phone the problem becomes solved. But the problem comes again after a week or so. Any suggestions guys??

I also have this problem, but if I wait a couple of minutes the touchscreen
becomes responsive again. Half of the screen works when it's unresponsive (right half of the notification bar and down). It's quite annoying but I cannot afford a new phone at the moment.
I'm also wondering if this might be temperature related, this problem reoccurred very often during the summer but stopped during the winter. But now (spring) it's back again.
My problem got worse and the phone became totally unresponsive, changed it, got a new phone.

exact same problem here, mine works when it feels like working, totally random, I simply can't understand why, I doubt it's the temperature... I think its in the device theres something wrong, I smack it numerous time and it works right after a big smack on the screen, or rub your whole hands on the screen, also, the angle you are holding the phone affects this problem, if none of these work, a phone restart always makes it work at the beginning. Oh boy did my phone took and taking much beating... oh well, I wish I could permanatly fixed the problem here, as I was thinking of handing the phone to my brother when I upgrade, I'm using CM 6.1.
I still recommend the same thing that i posted earlier here, her screen still works perfect.
I had the same problem few months ago. The problem is with the touch digitizer. I bought a digitizer on ebay and replaced it myself. After that my phone has been working fine. Its not that hard to replace it if you have a small knowledge about hardware.
I use to get that unresponsive screen issue only in the summertime, plus it gets worse if I add humidity (read: sweat). I just need to give it some time then to dry off/ cool down outside my pocket, and it's all fine again.
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

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.
