Hi, Just wonder if you still have the screen problem (register the wrong place when click) after the upgrade.
No. You should check out the humongous thread on google support forums. Googe have now abandned even giving updates on this serious problem.
http://www.google.com/support/forum...8e&hl=en&fid=04134c63c784258e00047fdfe09ae547
p.s. no fix in ere36b either (as im running that now and still experience this problem at random)
I don't understand this issue, I just don't see it on mine at all, no matter what ROM I install ... there has to be something more to this than a simple fault across all handsets ... either select faulty ones or some other factor. Mine just works 100% as expected at all times.
That said I have had no 3G issues either, no matter what radio version I use. Perhaps I am lucky ?
I think its because people are touching the edge of the screen while pressing with the other causing it to register incorrectly

That is not it, there are plenty of videos that show the touchsreen misfiring while just laying on the table. Also, the way I hold my phone I am never touching the glass surface other than with the one finger doing the touching.
With regards to some people not seeing it, this issue is very random. I can go for days without noticing it and then out of the blue it would come back, most annoying when it happens while typing something.
There is another somewhat related issue with the sensor on the n1. If you download an app called multi touch paint and try to draw two parallel lines simultaneously from say top left corner down to bottom right you will see that the lines are not straight at all and full of zigzags. Only way that this sensor recognizes multiple lines properly is if you draw perfectly vertical or horizontal lines.
There is also a discussion on developer groups where game developers are pointing out this very problem of multi toch totally being screwed up where it switches axis causing your touch to register in completely the wrong place. From the comments of the android engineer it makes it seem that the sensor hardware is just like that, cheap and low quality.

I know, I have seen all these videos and attempted to re-create many times to test I have never seen this issue once.
Don't get me wrong I can understand it being a mare of you are having it, but I just dont ever see it.
after trolling the Google thread, it seems to me there are several scenarios everyone is lumping into "screen issues" and it's going to be hard to pin it down to one source
Mine happens (touch registers on the wrong part of the screen) when I am using certain apps (Ringdroid, Browser mostly) - a couple of things clears it up ; press the sleep button, kill all tasks if you have an app for it, or change to landscape mode. For other people it's the soft keys and/or much worse. Since mine clears up with a specific action, I tend to think it is software related.
With mine it used randomly to happen but only in the Launcher (never again since 36B). I couldn't point anywhere but if I selected any app with the trackball and opend ist everything worked fine again, also the keyboard on the launcher worked well. For me it seems that it has something to do with the launcher.
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.

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.
Does anybody in here ever USE the kickstand?
Does anyone notice that if you touch on the screen for more than around 20 seconds at the exact same spot, the touch will be suddenly lost. You have to re touch the screen to get back the response.
You can download a multi touch testing app and try and you will know what I am talking about.
The problem is also found on ATRIX......(please refer to http://forum.xda-developers.com/showthread.php?t=1000583)
I am now quite angry and wanna MOTO to have it fixed as soon as possible.
Does this manifest in any way in real-world use? I haven't noticed any touch screen problems.
There is a long list of things that people would like Motorola and/or google to fix right away: SD card, Video playback, Forced Closes to name a few.
But if a problem isn't noticed in every-day use, its not going to be much of a priority.
It'd seem more like something built in than just a bug that popped up.
At least as a developer, that's where I'd put my two cents. There's a reason for it -- although I guess I could see it being an issue if there were an app that made you hold your fingers still for 20+ sec, followed by movements on the screen... but I don't know.

It does, in fact, manifest itself in real-world use; when I hold the device with my left hand in the middle--as is usually the case--my thumb often presses against the black bar at the bottom (the one that has the time, navigation symbols, etc). After a few seconds, the screen fails to respond to touch; it does recover after a while, but until I read the op, I never realized the cause, i.e. I was removing my thumb from the bar. I was thinking of returning it, because I thought it was experiencing random freezes.
I would imagine this is a feature, whether in the hardware or implemented in the software. It's a pain in the arse from the device's perspective to be continuously polling a screen touch for 20 seconds or more.
I'm a developer too and unless it happens with _any_ continuous touch (moving or still) it's a feature not a bug.
However, if you were to touch and move for 20+ seconds then it stops responding, this is a bug, depends where and when (whether always or just in certain apps) it happens.

So, like we said before, no real-word manifestation.

I haven't been able to replicate this on my XOOM. Though, if the problem occurs on your XOOM as you describe, I can understand why that would be annoying. Maybe the problem isn't present on all devices.
I did try a multitouch testing apply. I had 8 of my fingers for more than just 20 seconds. Didn't experience a thing until I put my ninth one down. On other test app, though, it said xoom can support up to ten.

OK think I figured this out. I can replicate what you are saying. But, the whole screen doesn't lose touch sensitivity, only the menu bar. I suspect this is intentional, and part of honeycomb and not a flaw in the touchscreen hardware.
It just means that you have to remove one fingure from the menu bar before you can use it again. I can't see this causing any problem whatsoever in day to day use. Just an interesting quirk.
Don't forget , that the bar is part of the screen just like any other, if you're holding that in an app that doesn't support multitouch in such a way, it wont work.
One thing that always bugged me on my Android devices is that I can't drag the curtain (notification drop down) half way, keep hold of it and tap something inside then let go. But that's just the way it works.
Actually you are partially right. Its the honeycomb interface as a whole that becomes unresponisve, not the screen. For example if am at the home-screen and I touch the menu bar for more than 20 sec and hold my finger there, I can't open the browser.
BUT
If the browser is already open, and I hold down on the menu bar, the rest of the menu bar won't respond, but links in the browser work fine. So it's not the touchsreen that becomes unresponsive, its the Honeycomb interface.
Edit: after experimenting with different apps, it looks like my own observation isn't completely consistent. Some apps like the browser continue to respond. Others like Google books lock up. Not sure what to make of it all. But there are definitely cases where only the menu bar freezes and the app continues to respond.
Yeah, now that I know what causes this quirk to manifest, I'll just have to be careful not to rest my thumb on the bar. I must find some way to hold it firmly with my left hand; maybe some kind of suction device attached to the back.

Patient: "Doctor it hurts when I bend over."
Doctor: "Well then don't bend over!"
LOL Pretty much a universal soltion. But I agree just a quirk, doesn't seem to be a big deal, just don't hold it like that.
LOL, right!
When you play games you can easily observe this!!
For example you play car racing, you have to touch the "accelerating button" for the whole time. It will suddenly lose response and all the other cars pass me.
Another example is the mini squadron, you have to keep touching the "fire button" to fire. But after touching for 20 seconds, it losses response again.
It is so annoying when playing games. However, except this, other daily uses will not observe this problem.
AND my XOOM is the recent WIFI only version. Maybe only this version has the problem?
AND I am talking about keep touching on the same position on the screen. You dont have to use two fingers to have the problem.

I have the 4G/Wifi Xoom fully stock,
I had a similar issue yesterday, I bought one of those styluses for ipad, which do work for OG Droid and for the Xoom, had a drawing app open, set the pad down with the stylus on top, it did 2 things it start to constantly draw from tip to clip.
then I picked up the stylus, now everything seemed to be stuck to a center point every touch drew a center line to the single point for about 2 minutes, I put it down, had wouldnt respond to more pressing, then picked it up it finally returned to normal.
although I just topped putting the stylus on it while its on, and havent had the issue, but I have only played angry birds, and fruit ninja.
Wow. Not good.
One of the XOOM's biggest selling points is HD Video, and it doesn't do that well.
The other is 3D gaming. And now we're finding out the control is messed up! Seriously!
And to think I was looking forward to gaming on this thing while waiting 3 hours for my damn videos to finish encoding. What next.
I'm starting to have doubts about the XOOM again. Video and 3D gaming was supposed to be what the Tegra 2 was all about. Would like more feedback about how real this problem is, and whether games are really unplayable - is this a quirk or a serious flaw? Will have to try some gaming tomorrow. Would help if we could list games that are affected and to what degree. Maybe we can get some consensus on whether this problem is meaningful or not.
Games reported to be affected so far:
1. Car racing (which one?)
2. Mini Squadron
3. Mario Cart
Hey guys,
I was writing an app today and I was having trouble when pushing two buttons at once. I checked it out with Multitouch Vis Test and the same problem occurs.
What happens is that I touch in two places, then take one of the two fingers off. The tab believes that both fingers are still touching until the second finger is removed. This is quite frustrating. Has anyone else noticed this issue?
Hopefully this is just a software issue but I have a feeling it could be a problem with the touch screen itself.
I'll upload a video when I get home.
I tested with mine. I used Multitouch Visualizer and I was able to get up to 10 fingers simultaneously. It would also update correctly when I removed only one of them, six of them, whatever. Sounds like something is wrong with yours my friend.
Curious because mines on the way... Since these were given out free, does Samsung still provide warranty coverage as if the tab were a retail purchase?

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

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.
