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 ? "
Much more too it than that: http://en.wikipedia.org/wiki/Capacitive_touch_screen

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.
Hi All,
Just noting this here in case anyone gets this in the future, as I know how much Googling helps me with situations like this...
My Sensation woke me up as normal this morning with the alarm, but I went to turn it off and couldn't. The touchscreen was unresponsive.
Neither the buttons nor the screen itself seem to respond to any gesture.
I've had it on charge overnight using the charger from my HD2, and have done a bit of Googling to find the Desire and a few other models with similar issues, but only with cheapy chargers.
I've also found that it could be that it has been "over charged" and the device needs to settle the battery levels before it works. I've had it on all morning, but i can't really keep pressing the power button every few seconds to wake it up!
I have managed to get into the bootloader menu (it uses the power and volume keys fine) and have performed a factory reset - no joy.
I've also used the bootloader menu to perform a "recovery" - this ended in looking like its a hardware issue as all i had was an exclamation ( ! ) with a big red triangle over a picture of the phone. Guessing this isn't a good thing.
I've let Vodafone know, and they are sending out a new replacement tomorrow, but we shall see what happens.
I miss the damned thing already!

Good to hear your got it replaced.
I just can't understand how the touchscreen is related to the power adapter. The only thing I've experienced is when I tried to charge my friend's iPhone (using the apple charger) on my car inverter, the touchscreen got really crazy, was detecting taps on its own etc..

By the looks of things its to do with magnetic or electrical fields produced by the adapters, using unshielded (i.e. cheap) adapters can negatively disturb the capacitive system. At least that is how I understand it from what I've read. (I'm not an electrical engineer or anything)

Yeah, that's what I was thinking too... But when that happened and he told me his new iphone had gone crazy and he was accusing me of breaking it with my inverters etc. I was really worried about having to get him a new phone (at least I could convert him and get him an android ) but then he disconnected it and it was ok so my heart was back in place.
Btw, the Desire was charging normally with it.
Hi guys, I've looked online and couldnt find anything about this issue. So the touch-sensitive buttons on my display light up when I press the home button. The screen doesn't activate or anything ,they just light up . Interestingly enough, they don't do it if I touch the screen or another button at the same time. Weird. Anyone know what the deal is here? Or is it just a wonderfully done job of HTC's?
Second issue, a more common one, but the solutions provided didnt work for me. The screen goes nuts when I plug it into a USB port and sometimes when it's plugged into the mains. I can't use it properly and if I try to type something, it will just go berserk with the keyboard. It's very annoying because I can't control it at all. I have managed to find a way to half-fix it which is: I take any cases I have on the phone and make sure to touch the back of the phone with the same hand that I am using the touch screen with. But I can't use it if I don't do that, and even so it doesnt work all the time.
I tried the "aluminium foil" trick and the "pull the little metal flap" trick, none of them worked at all. Anyone know if there's something I can do?
Just to give you an idea of what I have, the phone is boot-unlocked, s-off -ed (using JuopuntBear) and running Android Revolution HD - with XE and Beats Audio. Using ext4 as recovery. Obviously, my warranty is non-existent at the moment so taking it to my network provider is out of the question (plus, that takes ages and I dont want to be that long without a proper phone).
So, what can I do? IS there anything?
Sorry about the long boring post though.
idk. One search i did said that installing htc sync helped. Other than that or loading up an RUU i couldn't say right now.
So would an RUU just restore me to the stock ROM? Because I wouldnt imagine that to be a solution, since It's been acting up since before I unlocked the boodloader, s-off-ed or did anything to it. also, I had HTC Sync for a while and it still went bananas. Thanks for the advice, hopefully, if this is a hardware problem (which it looks like, at the moment), HTC will say something about it soon.
My daughter's TF300T started acting strange recently. Sometimes it will just stop recognizing any touches from the screen. To unlock I often have to turn touch the power on/off button several times before the touch screen will respond. It sometimes reacts very slow. The tablet is several years old so no warranty. Device is not all original on the most current version of stock. No root as of yet.
So if I root and install a custom rom (thinking crombi-kk) would this possibly recalibrate and fix the touch screen?
Looks like hardware issue to me. Seems to be common with the tf300. I had it with a brand new machine, swapped for another.
Reviews are really bad with the sensitivity of the haptic buttons for volume control and on/off. Some people have said an update with better accuracy is required. This is a deal breaker for me and I have owned almost every phone since HTC started. Currently I own the u11+. Please give you reviews here after you have spent some time with the phone and possibly tweaked any possible settings to make your experience better. Thank you.
No issues for me. They seem to work as expected, though I rarely use the buttons. I am failing to understand why the reviewers are making such a big deal of this. Mkbhd's review seems spot on to me...
I'm playing around since a week with my U12. Can't find a sensitivity of the buttons that fits my needs...
My index finger touches the On/off button every second time I use the phone...don't know why they installed the button so deep...(or my hand is to big )
When I'm in the YouTube App or PubG in Landscape mode, the volume and power buttons doesn't work...
I'm a realy fan of HTC and owned all HTC flagships since the diamond...but that buttons drives me crazy!!!
Hope for an update
So far, I have no issues with the buttons. I went into it know that they weren't real buttons and didn't expect them to act as such.
No issues with the buttons for me either.
Here also no issues.
Grtz
Everything working as expected on my end as well. No issues at all.

I have just one issue with them, that sometimes they react if I touch the phone without even touching the buttons. For example I grab my phone (on the lower part) and suddenly my volume is all the way down.
Also if you have edge sense enabled, and you just pick up the phone you sometimes have the blue dots (to indicate that you're "pressing" the phone) visible - without actually pressing it. The dots go away shortly after you do something on the phone .... as if they calibrate itself or sth.
I have u12 plus for 12 days. For my use the haptics buttons are a real disgusting. In particular the power button. An involuntary light pressure is enough to turn off the display. Really unnerving. Every day makes me curse this thing. I'm waiting for an update, if htc does not fix these buttons, I'll sell the phone absolutely. Unfortunately, if htc fails it will only be because of him and of these useless experiments.

I have the same issue with my buttons, I'll be holding the phone below the power button and it will trigger the screen on or off. Also I noticed sometimes depending how i'm holding the phone I can't get the power button to react. This is my biggest complaint about the phone other than the software being the exact same since the HTC 10.
I don't have any issues with these buttons. Everything works fine for me. I'm already used to it after playing with the device for 3 hours.

Today i've received mine U12+ and I don't really understand why reviews complain about those buttons. They are fine really, when I press I fell haptic feedback. They are neither too easy or too hard to press, for me they are fine =)
I STILL have no issues with the buttons. I don't really use the power button to turn the screen on. I use the fingerprint sensor or a swipe. Volume button works great for me.
I've bumped the power button while using the phone, sure. Not exactly an issue to rage over for me.
My only confusion is that the button presses feel like a linear actuator (Taptic Engine), but the rest of the system's haptic feed back feels like a normal spinning weighted motor.
Hi, i have also Problems with the volume Buttons. They working like charme. But they dont working right in landscape Mode if there is any contact with my Fingers/hand on the display. I think the Buttons are being ignored if the "3 Finger gestures" is on limit.. Can anyone proof this?

Just tried to go in landscape mode, put my thumb on the screen and tried to change the volume buttons up/down and turn the screen off with power button. The buttons didn't recognise the presstouch here either. Don't think that's a problem though, but build in to the software.
Update; wait the do work over here!

Nearly every review before the phone was released: The buttons are horrible! Don't buy! Don't buy! The buttons stink! Why did they change them?! They're horrible! This is stupid! Don't buy!!
Nearly everyone who owns the U12+: What the *$% was the fuss about? The buttons work fine! Took me a few hours to get used to it, but I've got no real problems! They work just like regular buttons! Don't "not buy" just because you're afraid the buttons suck!
I mean ... do you think the initial//review devices were REALLY that bad and there was this huuuuuge improvement before the device was released to the public, or people just don't like change, or do they just have ulterior motives?
I get it's an $800 flagship with no headphone jack and rear glass with no wireless charging (but QC4!), but this phone has been EVERYTHING I was hoping it would be -- premium device with no notch, above-average speakers, IP68, sd card, snappy fingerprint scanner, bootloader unlockable and killer cameras. No buyers remorse here!
Well, I really don't get why reviewers are so mad about those buttons. If you wanted this phone because it's a complete package (well... almost, no Qi charging), don't let the button "problem" (at least for reviewers) drive you away. It's a great phone and my only grief is the lack of 3,5mm jack but I knew that it won't be here....
Btw
Usonics are really good
I have the U12+ now for 2 weeks and got used to the buttons. I mean, yes they could be a bit more responsive and i think HTC will fix that with an Update. If not, i am sure someone on XDA will. I really dont understand the bad reviews. No Notch, for real? Like it would make a phone that much better. No 3,5mm? Nothing special these days, get used to it. My battery on averange usage is great. I do watch Netflix, use Whatsapp, listen to Spotify and take here and there some pictures. I get 1,5 - 2 days battery. I am not a huge HTC fanboy but also cant denide that i really like what they did with the HTC 10 and M7. Its something new, wasnt there before and it doesnt mean its that bad, just give it some time to get used to it. Hope they fix some small issues with Android P Update. I would like to set the sensitivity for the buttons in the settings.
Sorry for my english
Everything works well here. Buttons and even the double tap for one hand operation no problem.
