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.

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.

I included a link to this thread, so please continue to post your experiences, even if you have experienced nothing of the sort described here. I want it to be as objective as possible
Thank you all.

It is annoying as i like to lay my phone on a table or desk and still use it.
Could it be related to this?

Def. Not as bad as that but it is annoying. Hopefully someone can find a simple mod to fix this. I wonder if using a case would get rid of the issue

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.

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?
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.

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

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.

Hello XDA! I bought a used (almost new though) HD2 a month or so ago, obviously I went straight ahead and flashed something else than WM 6.5 onto it...
However it has this weird issue with the touch being registered in an odd way sometimes...
Once in a while it will register a touch although I'm not touching the screen, other times it will freak out and register random touches all over the screen...
I notice this especially whenever i type...
(Look at the attachment for an example of this behavior captured with the pointer location in dev tools)
Is this a software bug in Android or is it my digitizer that needs replacement?
Thanks in advance
No one knows?
Never encountered a bug like this. So I have to say its your screen freaking out. Common problem with hd2 when they get overheated.
But you can always try other roms to see how it responds then.
Or possibly you accidentally touched the screen at the edge with your palm? I've done that loads of times before, and the HD2 only supports 2 fingers (also, it does this really badly from my experience).
I've noticed that I have to text slower than I actually can because it just doesn't register all of the points clearly enough :/

I've tried a bunch of different roms but they all seem to do it, I don't remember whether or not WP7 also did it though...
Overheated? hmm maybe because it does seem to happen more frequently when i text a lot but it might just be because i get more frustrated by it.

Perhaps, I'll have to see if i can replicate it with the phone lying on the table and only using my finger...
i sometimes have this problem too, but only when i have sweaty fingers..
i think it's the old generation digitizer. it's like drop of sweat are lying on the screen, making it freak out, cause the digitizer doesn't know where it gets touched.. so it jumps from here to there, and back and then somewhere else..
it always happens to me when im playing games on the pc:
i get a sms, i want to answer. i forget that my hands are sweaty after 2h of gaming and the screen freaks out. UNTIL.... i clean my hands and the screen on a tissue or so..
lol it even happens sometimes that it types something by itself, then sends it... >.<!!
probably you have sweaty hands too when this happens?
just try to clean the screen when it happens.. it could help
I'm wondering if other users have experienced this. I find that after spending some time with the Transformer 300, especially when moving the machine on and off the keyboard dock, the screen will start to act flaky. In some cases what I'm seeing are "phantom touches." The home screens will start wobbling back and forth, as if someone is half-swiping them. In one case, I was playing the game "Sentinel 3" and the screen started zooming in and out as if someone were pinching it. That's with the tablet undocked. With the tablet docked, sometimes what I'll find is that the screen will become un-responsive. I'll click areas like the app drawer ad nothing will happen.
This is all resolved by shutting the machine down and bringing it back up again. This has happened to me numerous times, enough, in fact that I'm pretty convinced I'll have to take it back to Best Buy. My only question at this point is whether to return or exchange.
The fact that shutting it down fixes the issues suggests to me that it's a software glitch, which could potentially be fixed with a future patch. But that also means that exchanging the device likely won't do me any good.
So I'm posting this to get some feedback from the community and see if others are experiencing these same issues. If not, then maybe I got flaky hardware (a loose connector or something).

I agree it sounds like software since the reboot fixes it but your issue doesn't seem that common. I've seen a couple now that are somewhat similar but not like the pervasive left screen glitch. I would try an exchange personally.

Well sorry to burst the bubble but doing a reboot to resolve the problem doesn't really rule out a hardware issue. A hardware issue can be intermittent, there's nothing that states that it must be permanent. Furthermore it might not be the rebooting that resolves it but the time that passes. In other words, the problem might occur only at 6:45PM and last for 30 seconds, if you reboot it you might not experience it again. You have no time machine so there's no way for you to really figure out when it will occur and for how long to find out what's causing it.
It's all tricky. Some errors can occur both due to software and hardware so it's hard to determine which is actually causing it for a specific issue.
But a few things lead me to believe it's hardware.
1. Why aren't more people experiencing it? A software issue results in far greater people experiencing it, especially for a group as homogenous as TF300T owners who all own the same device. The conditions are already ripe and unless a third party app is causing it, everyone is running the same code and therefore more likely to experience the problem. A hardware fault would have to be deeply ingrained into the construction, the likelihood they had let it progress that far is unlikely. Instead, it seems like a QC issue which only affects a few individuals like you.
2. Touch screen issues have been noticed in not just this device but others. It can take on the habit of registering ghost input, no input, etcetera. Happens on the Nook Color too. Happens when the device is unplugged but mostly when it is plugged in to a power source especially the wall mains. If you're not getting it from your wall mains, it's probably the device. If it is your wall mains there's nothing you can do about it.
3. There's nothing random about handling touch screen events so I find it hard to believe this is caused by software. It's more likely it's a bad touch screen feeding false events to good touch event code. The likelihood code is doing this and doing this where only you experience it and not many others (actually I've seen no other people complain about this for the TF300T and two other people complain about it for the TF101) is really low.
IMO: Just exchange it. If you make the mistake of never exchanging it you'll be stuck on that boat forever. It's probably poor QC. If the second one has the issue, that bumps up the likelihood it's a software issue as these issues in hardware are very rare and I don't think two possible units experiencing it is very common unless it was a far more common software issue. If it occurred again I would either exchange it again or get a refund.
So yesterday I flexed the screen (basically pushed up ay the back, center with my fingers and down at thes sides with my thumbs) and the tablet started bounging between the home screen and the app tray at regular, 1/2 second intervals. back and forth, back and forth.
I also discovered that if I hold the tablet in portrait mode with my left thumb about 1/3 of the way up and sqeeze, the screen becomes completely un-responsive. if I ease up the pressure, it registers touches. I discovered this by readong a post by another user that had the issue (though I think in his case his screen would go haywire).
So I'm definitely taking this back to the store. The only question is whether its an exchange or a refund. I absolutely love the concept of this tagblet, and when it works its glorious. So if I can find one that doesn't suffer from these issues I'd love to hold on to it.
Check the running apps it's most likely mem related
Hi,
I've had two of these for about a week now, one for my self, and one for my 10 year old. I had to go into settings and shut off all kinds of stuff that was attempting to auto updated right off the bat. These don't come with a ton of memory right out of the box.
If you press on the bottom left corner of your screen the two little squares, it will show you what is loaded in memory. Every thing that comes up on that list on the left hand side is a opened application that is actively eating up your memory.
The only way to clear these apps once opened is to power the unit off, and then back on.
On both mine and my sons, I shut off all the auto updates, there are a bunch of different settings, you really need to go through them and look too many to list but a bunch should be turned off.
I don't have any issues at this point, neither does my 10 year old, he's always playing games like Fruit Ninja and normally has three or 4 youtube windows in the back going with in 5 minutes of turning the thing on and no issues.
Mine I use more for business related stuff, and also no issues. However right out of the box the first day it was a bit flaky. They both run smooth now.
I'm just waiting on some one to give me a root app for .26 since the second I turned these both on they updated the OTA firmware which took them off .17
Anyway I hope this helps.
Good luck.

Sorry didn't see the post about issues with where you pressed the screen. That one sounds like you may need to take it back in to have serviced. I tried what you said with squeezing the screen, and pressing the back in different spots. Nope, no issues like that. I would say it requires service.

The button you refer to in the bottom left is the multi-tasking button. If you press it and swipe an app, it will be removed from that list. Android usually runs fine with lots of apps sitting in ram. The only real exception to this is apps that are poorly coded and will try to run in the background all the time.
If you want root look in the development section, there is a simple utility to let you downgrade to .17, root, voodoo backup, update, and restore.
I have same/similar problem see other thread

See here for my symptoms.
So, last night I took the tablet back to Best Buy and exchanged it (actually, had to drive to a second Best Buy because the one where I bought mine was sold out!). So far so good. Though I've only had the replacement a short time, I'm feeling good about this one. No hiccups so far. And upon running the initial setup I remembered that even during the initial setup of my first one, the screen had become unresponsive once. All in all I've got a good feeling about this one. And I do desperately want it to work because, man, I love the concept and execution of this thing.
Have you tried the creaky test with the new one to see if it's a manufacturing issue indicative of all TF300T's or whether it was just an isolated QC incident?

I'm wondering if other users have experienced this. I find that after spending some time with the Transformer 300, especially when moving the machine on and off the keyboard dock, the screen will start to act flaky. In some cases what I'm seeing are "phantom touches." The home screens will start wobbling back and forth, as if someone is half-swiping them. In one case, I was playing the game "Sentinel 3" and the screen started zooming in and out as if someone were pinching it. That's with the tablet undocked. With the tablet docked, sometimes what I'll find is that the screen will become un-responsive. I'll click areas like the app drawer ad nothing will happen.
This is all resolved by shutting the machine down and bringing it back up again. This has happened to me numerous times, enough, in fact that I'm pretty convinced I'll have to take it back to Best Buy. My only question at this point is whether to return or exchange.
The fact that shutting it down fixes the issues suggests to me that it's a software glitch, which could potentially be fixed with a future patch. But that also means that exchanging the device likely won't do me any good.
So I'm posting this to get some feedback from the community and see if others are experiencing these same issues. If not, then maybe I got flaky hardware (a loose connector or something).
