Just confirmed this issue on my Omnia7.

This is retarded. Capacitive screens don't work that way.

not having any problem on my omnia 7...tried everything to try emulate some of the effects reported! not seeing any deterioration in sensitivity!

Not a pickle from my Omnia 7, Still as lush as ever and responsive as it should be, i've been mostly USING in on a pillow/soft surface when it's laying down next to me when i'm home and sitting here for hours on end.
Loving it even more when all these bugs/glitches come out and it's stomping them down.

I feel I should come back to this and apologise as I have found a pillow which messes up my phone's touch responsiveness too. Interesting.

What kind of pillow? This smells of static to me, seeing as capactive screens rely on the tiny electrical charges in your body. Polyester fabrics getsquite static, do they not?

It happens to me when I place it on my desk...

I noticed the same thing...but I didn't associate this with the soft surface, the touch screen doesn't work when it's plugged into the charger

It says that in the manual! Page 12:
The Manual said:
While the device is charging, the touch screen may
not function due to an unstable power supply. If
this happens, unplug the travel adapter from the
device.

Of course, that's assuming your power supply is dodgy...

I believe the manual is a load of BS. My iPad works fine when connected to my powerpoint. I've noticed that when the Omnia is charging via powerpoint its screen sensitivity does go down, BUT, when you hold the phone with your other hand, or even just touch part of the rear/side with one finger, the screen starts working flawlessly.... imo it could be some design flaw regarding conductivity

When I place my Omnia 7 on my car phone holder (from Capdase), the screen does not respond at times, and I can't seem to find any pattern why or how this happens. Sometimes it works, sometimes it doesn't. Once I take it off the phone holder, the screen is working fine again.

I wrote it in the other thread... but I had this problem too and after I flashed the newest firmware it was gone. Now the screen responds perfect no matter where I place the phone.
You should check the thread with omnia firmware out

Another solution I found is that you would need to Hard reset your device not through the settings but turning off and than press/hold volume down + camera and power on. Than press the middle button twice and than you will not have anymore problems with touch screen.

o really?! I thought it was just magic and the magic couldn't work when the phone was placed on soft things! im so glad someone with intelligence could teach me about this capacitive thingy whoever he is!
you have completely cleared this up for me - i now see the error of my ways. must have been having hallucinations or something. sorry for this disruption everybody!
i hope the next version of our phone uses magic because that would be really cool!
on a side note to that, after updating my firmware yesterday this dosnt seem to happen anymore. stupid hallucinations!

Had this before, after the firmware Upgrade the Problem seems to be resolved but after some time ( 1 week or so ) it's back again.

Looks like there is a fix for the laying-flat-issue for the Focus:
http://forum.xda-developers.com/showthread.php?p=11077163#post11077163
Maybe it works for some issues with the Omnia 7 as well. Did anybody already try?

Yes, have the same. If I put it on my couch, or bed. Sometimes also on hard surfaces. Doesn't bother me too much though, but it is weird.

I'm not trying to toot my own horn here...but I was literally the first person (or one of them at least) on Microsoft answers, Youtube and forums alike to raise concern about this issue.
It's a conductivity problem. As long as one hand is touching the back of the phone (sometimes near the top or sides too) then the touch screen will operate normally.
The reason it stuffs up when you have it flat is because you're not touching the back of the device, hence the conductivity flaw.
Check all this, it's a problem with the Omnia 7's, deal with it or chose another handset. I ended up keeping mine, I can live with it.

Has anyone dismantled an X1?

Hi,
Just wondering if anyone has fully dismantled an X1 - and if so, do you know if there are water indicator stickers on the inside of the phone?
So far, I can see two on the outside (one on the battery itself and the other where the battery contacts are on the phone itself)
Thanks in advance!
some where on youtube there is a vid on dismanteling an Xperia

It doesn't appear to have any on the inside.. however I'm not sure if the 3 rectangular white things on http://www.phonewreck.com/wiki/images/thumb/a/a8/Xperia_x1_pcb_2.jpg/800px-Xperia_x1_pcb_2.jpg are teh same as the water indicators on the outside.
Yes Dismantled it.
Mine fell down. Touch stopped working and so did the finger scroll sensor. The touch worked in landscape but in portrait it wont work.
Opened it and found the connector slide cable (similar to ones in samsung slide phones) unplugged. Guess the shock of the fall made it stick out.
Anyways plugged it back in and whoa....Phone was as good as new.
For thoe whose touchscreen stop working, I suggest please first try the "BOAN" method. (Battery off all night). Insert the battery in the morning and the screen works miraculously.

Or make a hard reset may i add...
Or full flash instead thats worked for me...
Hard Reset did not solve my probem though. I tried flashing to Generic R2a0010 as well. Did not work.
One more thing before i tried the BOAN methodm was inserting a visiting card between the screen and the casing especially the four corners to wipe out the dirt. beleive me, its the small particles that pile up and sometimes pressurize a particular point disrupting the touch mechanism. I got my X1i only 20 days back, and i stay home or office and believe me there was enough dirt residing in the corners. I was actually surprised why they had such a big gap between the screen and the casing.
Anyways, since i did the flash, I flashed mine with the latest R3A0010. All's well in my x1 except that custom ringtones are not loud enough.

My Hero does the weirdest thing...

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.

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?

EVO Video of touch Screen Working

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.
Does anybody in here ever USE the kickstand?

Reduced Touch Response

Good Morning Guys,
I have a strange experience to tell to me fellow users. After using my Samsung Focus, I placed it next to me, momentarily, on the sofa. With the device still on, no lock screen, I turned to it and tried to flick the start screen up to get to the marketplace (which is on the bottom of my start screen). There was no response.
I picked up the device and the start screen scrolled to the bottom when I flicked to the bottom, as I normally experience.
I placed the phone back on the sofa and tried to perform the same task, but the screen was unresponsive. I propped the phone up against the back of the sofa and tried to the flick the screen up, no response. I placed the phone on a wooden end table - the screen responded to my touch.
Has anyone else experienced anything similar?
Thanks for your time,
M
Sometimes this happens to me. It seems my thumb gets better response than my finger, but maybe it's because I hold it up. Doesn't happen often, but it is a little annoying. Hopefully it will be addressed in an update.
THanks for your input. Maybe we need to have a greater electrical field
Shocking eh?
Same thing sometimes my phone thinks I'm clicking on something when scrolling. It just stops and opens w/e I was over. Also noticed it only happens when I use a finger that isn't my thumb

This happens to me when the phone is on its back flat...It's like it doesn't recognize that it is being touched. It is annoying but I think i will deal with it for now.

This is exactly what happens to me; however, for me it has to be surrounded by either fabric or placed on paper (although there is some slight touch responsiveness on paper).
However, if the device is flat on it's back and I hold the edges with my other hand, the screen responsiveness returns.
I was wondering whether electrical grounding and/or static electrical buildup is an issue.
Thanks for everyone's responses so far. Once I get a few more peoples responses (and maybe some suggestions !!) I may forward the issue to Samsung.
M
I have noticed this same issue with my Focus as well. At first I thought it was just in my head but it happens all the time when I lay the phone flat on my bed.
All of your situations have happened to me.
It has to do with whatever happens when you're holding it. Touch responsiveness and accuracy go way, way, way up when holding it. But if it's lying on something non-conductive or even in a dock of some sort, it gets funky.
I mention some experiences of my own in the Multi-touch Issues thread.
I"ve submitted the question to Samsung via their Community Q&A webpage. The question will show up in approximately 72 hours.

Interestingly enough, my experience on my Focus is the opposite of that..
i.e. when I place it on the table - the phone is *less* responsive compared to placing it on my desk mat (leather) - which is is more responsive.
Overall - it's not as bad as the video. The phone is just less accurate (i.e. I swipe the phone to move the tiles and it opens the program at the start of my swipe instead of moving the tiles). In the hand, the phone is very responsive - and - if I touch the top/bottom of the phone with another finger on the same hand as my "swiping" finger - it's responsive no matter what.
I too find the focus touch sometimes screws up, it happens randomly, also the browser seems to scroll not as smoothly as at first.
I'm really looking forward to some Microsoft updates, but overall the phone has been really good, I've even got adjusted to the onscreen keyboard.
Using focus now.
Its also the first phone that works well enough I have used where I don't mind browsing my morning sites on and not miss my laptop
The touch buttons really piss me off though, I always press them accidentally.
I just discovered this issue recently and its very annoying to me. Seems to be a problem to the ground of the device so I feel it is a hardware problem. Just watched that video of the HTC Incredible doing the same thing and it seems to be what the case is. Girlfriend had to brag about saying "oh iPhone doesn't have that problem blah blah blah" and started using it on the same table.
Wow its like you guys read my mind. I was showing off the phone to my brother and it was laying on the kitchen table when it started having the same exact issues. Could it be a hardware problem? Im about 2 second away from returning this phone tomorrow. Too many little annoyances.
This guy has the same problem on his Samsung omnia 7 http://www.youtube.com/watch?v=o52nzpzg8Aw
Haven't forgotten about this thread. I have been checking the Samsung website everyday for my question; however, it has failed to show up. In the next 2 days I'll be contacting Samsung directly via telephone to discuss this issue.

It's got the opposite problem. It only works when you don't touch it.
My brothers Focus either A) just started doing this, or B) he just noticed it.

Screen sticking

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

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 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.
