I just wanted to share this, since I was able to replicate this issue with three different phones, also asking if other people are having the same issue.
I am using my Samsung Nexus S for three days.
I noticed that the back button (the first capacitive button on the bottom left) appears to have an hardware problem.
Basically normally it works fine, I mean when I'm not using the phone for some hours.
Then if I start to use the phone, after a moderate use (example installing applications from the market, browsing etc) the button gets less and less sensitive.
After some minutes it gets really annoying.
To make it work it is necessary to use a really stronger pressure with the finger, and it is not even always working!
I am planning to return my device, but today talking with some people/colleagues I discovered that two of them have exactly the same problem.
I'm suspecting there is a batch of Nexus S phones with this glitch, I am curious to know how many people have the same problem.
Note:
At first I thought it was a general issue of the capacitive buttons. But I can't replicate the same problem with the other three buttons, they work very smoothly just lighltly skimming the finger over them, even after long usage.
Anyone with the same problem? What is your experience with this button after some usage?
Cheers
I want to say that I noticed something similar the other day, but it was short-lived, and I'm not 100% sure. It wasn't long enough or bad enough to make me think the phone is defective, but I'm a bit used to funky capacitive button responses from my N1 days.
I can't reproduce the issue right now, though. How much usage are you talking about needing to duplicate?
Does your phone get hot, or feel hotter than normal when this happens?
I'd see if there's some particular pattern or software that seems to trigger it if you're interested in trouble-shooting.
The problem goes away when I don't touch the phone for a while (it seems that 1 hour is enough to reset the problem).
It seems "recharging".
Then with normal usage, nothing in particular, just even browsing in the settings/maps/market/browser etc., in few minutes the problem appears. The button definitely loses his "power".
It's very annoying, and my friends confirmed the same behavior.
EDIT:
Forgot to sat that the phone is not getting hotter, everything else is really normal.
Cheers
Mine definitely can be used for much more than a few minutes without the problem you're describing appearing.
I'd take it back. Factory reset the phone to protect your private data before taking it back. After the factory reset, you might want to test the behavior again, if it went away, the phone's not defective, you just had some software glitch.
Reminder, factory reset erases everything on the phone, so if you do it as troubleshooting step, be prepared to have to set the phone up from scratch again...I'm sure you knew this, but just covering my butt in case you didn't. It's a good trouble shooting step no matter what if you don't mind the hassle of re-setting things up.
I have a similar experience with the back button. Not sure what to think yet.

I had a similar problem when I had the Vibrant. Just exchanged it and luckily I got a better one without any problems. I did find out though if you are using the screen protector that came with the phone, it can cause this type of problem.
No problem, I will try everything tomorrow. This is not my primary phone (still loving my rooted Nexus One with CyanogenMod 6.1.1 ;-) I can't renounce to the colored trackball for the different notifications), but just a "dev" phone for testing purposes.

The app NOLED from the Market may interest you if you can't live without trackball style color notifications. Seems to work fine when I tested it.

Thank you, giving it a try.
Anyway, today I factory-reset my telephone and the problem of the back button is still there. I am returning the device.
Back button non responsive
Hi,
I just got my new nexus S (about an hour ago) that I was really excited about and am faced with a problem with the back button too.
Its got factory settings, so it cannot be a downloaded software issue. Also, I have not yet charged the battery at all, its still running on the same battery power that it shipped with.
The other buttons at the bottom of the phone (home, menu and search) all respond fine, its only the back button that does not seem to work. After going through this thread, I tried long-pressing the button, hard-pressing it, pressing just above it, below it, etc. It just wont respond. I had removed the screen protector it shipped with, so that cannot be the issue either.
If this is a known hardware problem (i.e. others have faced it too), irrespective of whether it is acknowledged by Samsung / Google, I'll return the handset. I do not want to spend a fortune and be landed with a handset that does not work - forget working as desired, but it does not seem to be working as designed !
Thanks & Regards,
Rohan
Yep. Definitely a problem here with the back button. There's also two other threads here about it.
I'm having similar problems. I have to touch the button just right for it to work properly

I was experiencing the same thing with my Nexus S, wasn't sure if it was the case I was using! Took of case and still had problem. I eventually returned mine cause it seemed like it was getting worse! I have a new one worth no problems, definitely a hardware problem! Return it!

those buttons work over the heat of your finger. thats why after use it doesnt get as responsive. its because the screen is also heated and the heat of the screen is effecting the buttons. thats why you need harder pressure for the phone to understand this is your finger.
same issue was with Nexus 1. less responsive buttons. thats why there is a bigger gap between the buttons and the screen for galaxy S phones. i dont know why they did such a thing again with the nexus S. its like samsung didnt learn from anything from HTCs mistake.
They work with capacitance, not heat. Hence it being called a capacitive screen with capacitive buttons.
I think this is true ...
I have an HTC Desire with AMOLED screen.
When I play a finger intensive game, like "SkyForce Reloaded", after some times, the touch is not registered.
Then I must stop for a while, or change finger
Try that, you will know what I meant.
But, I don't have issue with the back button on HTC Desire because it is a hardware button. I am just trying to explain about loosing touch registration because finger interaction on (s)amoled screen.
PS: SkyForce Reloaded is an old school shot'em up game where you control a little space ship with your finger, shooting enemies.

The Desire's digitizer is the same Clearpad 2000 which is used in the Nexus One (and quite a few others), the problem there is that it's pants.

lol, isnt called like that because it registers the heat from your fingers. thats why if you try to use a pen, it wont register . and thus. the screen is NOT resistive type "where it will recognize anything since its being pushed by force ? "

from your link
"A capacitive touchscreen panel is one which consists of an insulator such as glass, coated with a transparent conductor such as indium tin oxide (ITO).[7][8] As the human body is also a conductor, touching the surface of the screen results in a distortion of the screen's electrostatic field, measurable as a change in capacitance. Different technologies may be used to determine the location of the touch. The location is then sent to the controller for processing.

I just got the 32G version transformer. There is a very annoying problem with the touch screen: sometimes it is not registering my touch at all, sometimes it seems that you have to push hard.
I am not sure if this is the touch screen problem or the system is busy with something else?
Anybody else having the problem? Any ideas to solve it?
The firmware is the latest version.
I too have noticed this issue from time to time. Not sure what it is though.

The touchscreen does seem a bit insensitive on my 16GB TF. Not necessarily unusable, but sometimes I have to touch a button a couple times to get it to respond. Most often the menu button that appears in the top right corner of some apps.
I am pretty sure this is a software related problem. Sometimes, the touch screen feels quite responsive.
What is the official way to report problems to ASUS?

Indeed. The touch digitizer and even it's driver works flawlessly - start Fruit Ninja HD and you can enjoy most responsive multi-fingers (4 or maybe more) touch ever.
But everything except games is considerably less responsive to touch.
The touchscreen on mine just completely died. Completely not responsive. I wish I could blame it on a faulty app or something simple but I put it to sleep and when I woke it 20 minutes later, I can't do anything with it. It responds to all the physical buttons just fine and the screen rotates and everything but it just doesn't respond to any touch.

I just installed Fruit Ninja HD. Although I am a newbie in cutting fruits, I am pretty sure the touch screen just doesn't register sometimes, even in Fruit Ninja.
My firmware build number is: HRI66.US_epad-8.2.3.9-20110423
Coming from Xoom, although the TF's IPS is much better than Xoom, but the touch experience of the TF is much much worse.
Sometimes you have to press hard and longer to register, I am wondering if there is a way to change the touch screen's sensitivity?
Whatever reason it is, it should be very easy for ASUS to reproduce the problem and fix it!
Try the app Multitouch Test in the market. It seems to be a lot more sensitive than some of the other apps are (or even the OS) regarding touch sensitivity. (Or at least it seems to be)

Thanks. Downloaded and tried.
When it's normal, it can track 10-finger touch easily. However, the main problem seems to be the response time for repetitive touches. The system seems to be not able to keep up with normal typing speed touches. It will register several touches, then non-responsive for a while. If you wait a while, like several seconds, it will respond again.
Is there a good APP to check CPU settings and utilization ratio?

Interestingly, this thing is mentioned in Engadget UK's review (http://hartantolestari.info/search/asus-eee-pad-transformer-screen-is-not-working)
A lack of responsiveness is also evident throughout the Android UI. Aside from a delay in activating the function you’ve selected, there are also troubling instances where input isn’t registered at all. That leaves the user with no less than three potential scenarios when she doesn’t see an immediate response — she could be looking at lag, an unregistered tap because of software, or an unregistered tap because the physical input was too light. Such uncertainty doesn’t build a great user experience and the Transformer, unfortunately, doesn’t offer a great user experience. Much of that is, regrettably, down to Honeycomb itself. It’s not a finished product yet. It’s actually a fair distance away from a finished product. Some apps are done to absolute perfection while a lot of the “glue” bits, the stuff that goes between the apps and basically makes up the OS, is either confused, not responsive enough, or broken in some other way. Let’s take these things in turn, starting with the good parts.

I would reccomend against pressing hard. That is a good way to damage the lcd panel and the digitizer hardware. Capacitive screens dont register pressure just electircal conductivity from skin touching the screen. I would say any lag you are seeing is most likely software based as others have said.
Sent from my Transformer TF101 using XDA Premium App
Hmm, I have tried rebooting the device many, many times and still no change. I wiped user data hoping it would help (nope). I just don't understand why the touchscreen would stop being responsive to any input. It wasn't jostled around or treated badly in any way. I just had it in my backpack, which I was carrying by hand and the Transformer was in a padded compartment.
Overall, I am rather disappointed and disillusioned with Asus. The Transformer's terrific when it works but I've had to deal with the deep sleep issue at least once a day and then to have the touchscreen go dead entirely is terrible. The first I can see being a software issue that can be fixed but the second is probably shoddy hardware.

Cold reboot is holding power button until TF shuts down, ignoring shutdown dialog.

almost seems as if they didnt test the xoom. it feels faster than the tf bc its screen is more responsive.
i wonder if the screen could be calibrated manually with the config.ini lie the nook color.
Here is some update: after the TF slept for a night, I pushed the power button. The touch screen is just not responding at all on the lock screen. I let alone the TF for half an hour or so, pushed the power button again, now the touch screen worked fine. Unlocked and into the home screen, no problem with touch for about 30 seconds, then it becomes intermittent again.
I will call ASUS support tomorrow. Hopefully there will be some firmware update very soon to address this, otherwise, I will have to return it.
The weird thing is that if this is a software/firmware issue, lots of people should have reported it.
OK, I have created a case at vip.asus.com/eservice/techserv.aspx
Looking at some Youtube clips reviewing TF, their touch screen seems to be fine. So this might be a bad unit. I will return it next week (bought from local Fry's) and hopefully they have replacement units!

Good luck! I got mine from Amazon and they are completely out of stock. The only option is to get a refund since they don't have an expected in-stock date so the CSR can't put a replacement order in for me. Every online retailer I've looked at is also OOS. Hopefully more come in soon.
I also spoke to Asus and they are willing to repair mine but not to give me a loaner or just outright replace it. That is really too bad. I was hoping they would be more like HTC, which has great customer service in my experience and gives out replacements at the drop of a hat. If the Flyer wasn't such a POS, they would have had my business.
Having problems with the touch screen on my sensation and this has now happened on my secound phone! both phones were ok out of box but after a few days first noticed problems from lockscreen as phone would not always unlock when draging app icon into circle then slowly geting worse until would take several swips on screen to even unlock! then started noticing similar problems in norm opperation? sometimes works ok but some times freezes up have tried factory reset and no differance. very strange having this problem on two phones?
Does the touch screen stop working completely?
Mine did that on Monday, had to get a replacement.
it seams to stutter once awake works slightly better? but still not responsive
I've noticed that the proximity sensor and gyroscope are being used aggressively to filter accidental screen presses.
For example, if I place my sensation flat on a table, the lock screen is very hard to unlock. If i place my other hand near the proximity sensor at the same time (or tilt the phone towards me) it unlocks easily. Until I identified this functionality I was beginning to think my right index finger was unsuitable for touch screens (since when placed on a table I tend to use my right hand, but otherwise use my left to unlock).
Hopefully this will be tweaked with future updates.

I am having the exact same problem, for example on the lock screen I would swipe up but the ring will move slightly, and one icon I.e the camera icon will move towards the ring, another grip which is buggin me is that it will miss screen taps, I.e when texting or clicking an icon one tap will go unnoticed by the device resulting in either a missed letter, or the app not opening. This also goes for the 4 command buttons at the bottom, it happens on these too. I also get the occasional lock up.

As I stated before, I experience this problem but it only occurs when the phone is laid flat and my hands are well away from the proximity sensor at the top left of the screen. I can say that the part you are describing with the lock screen is 100% the same problem I come across in certain situations.
Please test to see if the problem is still present when the phone is tilted in your hand and, if you are laying the phone flat when you experience the problem, try putting your other hand near the proximity sensor when you try to unlock.
If this happens as I describe then it is most likely a software bug which only affects users who have particular phone use habits.
Saying that, as you are having quite severe symptoms, during general use, it may be that you have a faulty proximity sensor in your phone - leading to missed screen taps when the phone thinks you are not touching the phone.
Well I laid the phone flat and unlocked it no less than 20 times, each worked flawlessly no problems at all..... Seems to have me baffled
Yes I've been having the same problem. First noticed it when trying to unlock it (phone was lying down), couldn't get the circle to move. Have had one complete touch-freeze. No input possible, however volume and power button worked. Took the battery out, restarted, and it worked fine.
I notice that input can be difficult sometimes, hit and miss or just have to push harder. Strange. Seems like a software issue to me.
edit: just had the same issue - circle wouldn't move. After picking the phone up I was able to unlock it, however still not as easy as it should be, a bit jerky.
Both my evo and my g2 had a grounding issue, for example if I had the phone laying down on the couch or bed, the screen would not respond to touch but if touch the phone with a finger and try to unlock it with my other hand it would work normally.

The wildfire (my friend's got one) has this problem too. You have to keep touching the metallic housing for it to detect any taps.
You are correct, aim1126. I never considered grounding to be the cause but after re-testing it clearly is.
I guess it is a side effect of having a conductive unibody. So basically there will be no software fix, we just have to keep constant contact between our hands and the unibody. I wonder whether a rubber bumper would actually make this problem worse?
Edit:
Actually, the screen seems to adapt to not being grounded properly after a couple of presses. It works fine for me by the third time I touch the screen - weird. Well at least it is only a minor annoyance!

My wife uses a G2 and I wouldnt call it a grounding "issue" honestly seems like more of a feature to make sure you ment to engage the screen.. Its kinda cool IMO
As far as the screen being laggy this sucks since I wanted to upgrade from my Vibrant to the Sensation.. I also am not sure its a software issue you guys are having.. I am running Sense 3.0 with gingerbread on the G2 and it is very smooth.. The option to silence a call or tirning on speaker phone by turning the phone over is neeto torpedo..
I'm having the same issue, from lock screen I drag the circle up and it just stutters. After a few tries it usually works, once unlocked the touch screen appears to work fine. I'd expect the issue would continue after unlock if it was a hardware issue.

That's very bad. Flaky lock screen is not good, and the example of not being able to scroll through apps without it running one is a killer. There are many times when scrolling through a list of selectable items is necessary.

Issues with touchscreen being unresponsive.
Important Isuue usually appears at least after a week of owning the device
Quick test:
Lock device. Unlock, launch camera app in the lockscreen, take picture, try pressing back button, see if it responds straight away or with a delay. Test it with all apps on lockscreen.
Issue unlocking ? I.e dragging circle to the middle?
Bottom of a screen not responsive sometimes.
Back button slow to respond.
Apps launching when you try to change screen, i.e. phone registers swipe as a press.
http://www.androidpolice.com/2011/06/06/is-your-htc-sensation-having-touchscreen-problems/
CAUSE Grounding pin not touching back cover, which causes (by the looks of it) build up of static which messes up touch screen.
FIX Best to use in conjunction with fixes below.
POSSIBLE FIXes if above doesn't work, which it should, but don't expect immidiate results.
1.Shut down phone and pull battery out for at least an hour (i recommend overnight). Press power button as to turn phone on, which in theory should discharge all the left over current in the hardware.
Give it a go and let me know if it works.
2.Letting battery discharge till phone turns off,put on charge and don't touch it till it's full.
I want to thank abrown0809, eliteone, stuart0001(legendary patience ), zmfl, maschenazi, nugzo and all other people i forgot to mention for sticking with me while trying to work out FIX. Thanks to all the posters too.
I take NO credit for the fix.
Poll is here to show how many people have this problem to HTC, not to work out what percentage of users have it, as it will definitely be incorrect.
Vote yes if you EVER experienced touchscreen problems, even if its gone now.

Only real bug is that non HTC widgets sometimes get flickering rainbow coloured stripes but they are strictly attached to the widget and vanish once I replace the it. So this should not be a display problem especially as the HTC widgets are never afflicted.

all of the above in terms of problems. unlocking problem, bottom of the touchscreen not being responsive, swipes registered as taps fairly frequently, issues with wifi cycling and never connecting, and it has ruined the SD card it came with (do the point that it gets detected by my win7 computer but crashes explorer, and on my mac it just isn't detected) as well as the 16GB microsd I foolishly swapped in from my DSLR.
Did I mention that I still am absolutely in love with the phone?
Hmmm, still a bit random.... We just need to find a common factor. If anyone spots anything in common, just mention it, even if you are not sure.
I appreciate this thread. I am still considering purchasing this phone but the two major hold backs are the wifi signal deathgrip issue and of course the touch screen. I kinda went through this debacle with the mt4g and don't really want to go through the hassle again of finding a working model.

Did those with or without problems use a screen protector?
I left the stock screen protector on my unit and it works beautifully. Maybe because the touch screen unit is slightly displaced, static build up on the gorilla glass causes issues with some unit?
HT15RT works perfectly
I just received a used nexus s i9020t and I've noticed that whenever my phone gets slightly cooler than say room temperature the hardware back button stops working correctly. When the phone is "cold" if I have BLD turned on and wait till the back light goes out I can press the back button when otherwise it wouldn't work if BLD is turned off. Does this make sense to anybody? I can try and clarify if it doesn't. I'm worried that its a hardware issue and that I'd have to get it fixed somehow. I just bought the phone and I'd rather now put more money towards it.

I'd like to mention that it is responsive when the phone is "warm". Its a really annoying thing and I'd like to get it figured out

I've not experienced your issue, so it might just have something to do with wiping and reflashing your current ROM (especially if you didnt wipe everything from GB to ICS). Though something to note: the "soft" buttons at the bottom use the touchscreen. You can witness this by going on a long web page and scrolling off the screen and down onto the soft keys, and notice that you'll be able to scroll left/right and up/down where the soft keys are.
This just means that if there is an issue with these, it falls back on either a software issue or touchscreen issue. Might help with diagnosing, ICS settings -> dev options has a good option to diagnose touchscreen problems.
I think the capacitive button mechanisms are different in the i9020 and i9023. I've had both and I've noticed that you can scroll around beyond the screen parameters with the i9023 but I cant with the i9020. Maybe somebody can correct me if I'm wrong. I've done some research and it sounds like I may have to pull the phone apart and try to take off some of the paint on the back button. Another suggestion that some people have is to slightly tighten the 6 screws on back of the phone under the back panel. I did that and its sorta helped. I can deal with it now but if it gets worse I may have to take the phone apart which is something I don't exactly wanna do. Btw I did wipe everything multiple times and restored from a backup and I didn't notice an improvement until I tightened the screws

You have a good point there, I assumed they were the same but they may be different, I've never experienced the i9020 to comment.
Good luck with your problem. You might try tightening only the screws near the back button and loosen the others a little, possibly giving it some leverage.

For a few months my phone has had a problem where the screen will take control of itself or become unresponsive, it's not the phone being slow, because hardware keys respond perfectly. Scrubbing the screen with a Lysol wipe helps sometimes, but I'd rather just have the problem taken care of (it seems like it's caused by fingerprints on the screen, which isn't a problem on any of my friends' SKs and initially wasn't on mine either).
Anyway, when I take my SK to T-Mo, should I flash a ROM that at least looks stock for warranty purposes or will they not care?
If I do need to go to stock, how would I go about doing that? As far as I remember, I've never taken a backup in recovery and never ODIN'ed (stupid, I know), so I've no idea what to do. I can flash ROMs perfectly fine, but going back to stock is a mind-boggler for me (disabling Voodoo, etc).
Thanks
Mine always does this.
1. The optical trackpad detects the sunlight, strong indoor lights, etc, as movement and causes spurious scrolling.
2. Water on the screen or a finger just outside the boarder of the screen causes the touchscreen to get confused and either not respond or move on its own.
3. The touchscreen driver is prone to crashing. About half the times I want to answer a call or something, I need to toggle the screen off and on with the power button before it'll work.
None of this is because the hardware has broken. 1 is due to a bad design, 2 is inherent to touchscreens of this type, and 3 is just bad programming.
Ha! I have to do #3 all the time. Glad to know it's not just me. Ridiculous.
Also FYI, #1 never happens to me. I see people here curse that damn sensor all the time, but I have never had mine move randomly in sunlight, and it generally works pretty well for me as arrow-keys.
I also do #3 all the time, and have had problems with the optical trackpad in the past (I've since disabled it).
What the problem appeared to be was that my fingers are oily or something, explaining why wiping the screen excessively was useful. I passed on taking it to the T-Mobile store and instead ordered screen protectors from Amazon. No problems since I applied one.
Has anyone else encountered this, or is this a unique problem? I got through nearly a year without having this problem, so maybe something went wonky in the screen. Anyway, problem fixed
