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.
Hello all:
Today my power button has become nonresponsive. I've done nothing unusual with my phone but I do remember early in the morning it rather strangely vibrating 3 times while I was browsing something, and it wasn't a phone call nor an incoming text, and I'm wondering if that was a signifier of what was to come. In any event, the phone is functional otherwise, for I can still slide out the keyboard in order to wake the screen. However, I dare not let the battery completely run out, lest I not be able to turn it on anymore, and I can't do a reboot of the phone (or screen shot, for that matter) since the power + volume down button combo doesn't work; it just lowers my volume. Any help would be appreciated. Thanks in advance.
I had that happen once - just pop the back cover off & re-seat it, make sure it aligns properly. See if that fixes it.

good advice.
before closing the back lid, try to push the button with your finger nails.
if you don't feel the click and just feel mushy, then you are screwed. I lost my camera button in that way from day 1 and I thought it's the way it is.
You have to expect a tactile feedback with every buttons.
Hello. I just bought the Nvidia Shield K1 tablet. It is fine for the most part. However, I don't know if it is lag or touch sensitivity or what, but it seems to me that whenever I am scrolling, it is jumpy and erratic. When I let go of the screen, it suddenly scrolls faster. Sometimes even a full page down, even if I barely scrolled. Should I try to get a replacement? Thank you.
First make sure that your Shield power control settings are set to max performance. Or at least to optimized. Also try rebooting it. I have occasionally had that issue with my St but almost always its when I have my Shield power control set to my own setting which is at 50% CPU level or whenever it just needs a good reboot.
I know that mine behaves like this (worse actually) when I'm charging it with a 2.1a or faster charger. I chalked it up to the screen being less conductive while receiving a lot of power. Does it occur all the time?

I solved the issue by recalibrating the screen. hitting model number: shield k1 or one of the items in the about system like 10 times gets you to the calibration screen.
then hit calibrate. don't touch screen. then when it asks to reboot. reboot

What's the difference between Max performance and Optimized?
Does anyone else have a problem with touchscreen sensitivity? Idk what it is about this phone. The lag wouldn't bother me if it weren't for this. It seems like whenever I scroll I'm accidentally clicking on and touching things I didn't mean to. Its the biggest problem I have, on stock and CM.

Ahh, so I'm not the only one? This phone has a horrible touch screen.

Yes, I do. I'm used to my LG G Stylo I guess (and all other phones I have had). When you touch the screen it always assumes you want to tap and does not give you a chance to slide your finger. I'd say at least 50% of the time when I want to slide it jumps to the conclusion I want to tap! So it takes twice as long to doing anything because I always have to go back and try to get it right the 2nd time. Does anyone know of a technique with this phone to execute a slide the 1st time? Thanks.

Yea that's a good way of a explaining it. That's exactly what my phone does, although I just realized the other day that my glass screen protector may be part of the issue so I took it off to see if it helps.

have no problem with this. (6045Y).
It is really bad on the YouTube app. You have to be very selective on the screen where you touch to start the slide or it will start video instead of scrolling the page. They really need a setting with for millisecond delay for it to wait for a "slide" before it assumes a "tap".
Is there anywhere where you can make update suggestions to Alcatel?
UPDATE: I asked about this and made suggestion for setting here: https://www.alcatelonetouch.us/contact
Here is the response I got back from Alcatel support:
"Thank you for contacting Alcatel. It is a pleasure being able to assist you, I see here that your devices response is moving and reacting faster than it should as if it had a mind of its own. Have you modified your operating system at all? The touch panel sensitivity is not an option or something that can be adjusted through the settings.
Let's begin with technical troubleshooting by clearing the cache partition:
Turn off the phone and while it is off press Vol(+) and the power button until it is completely on. You will get a screen showing a triangle and an exclamation mark, scroll down with the volume keys to wipe cache partition and select it with the power button of your phone. Next, you will see the process wiping, formatting, complete. Once complete reboot system now using same button.
I look forward to your response and hope this is the result for your device."
I don't know how this could possible fix the issue, but oddly enough my impression is that it appears to have corrected it. I will need to test it some more, but my main culprits where Facebook (via the Hermit app) and YouTube app. I also tried several other apps. So far, so good. You might give it a try. I does not delete data or apps - only deletes temporary system used files. Google "Android wipe cache partition" and read what it does for more info. Good luck.
I don't think it's the problem, but what I would call it as the issue of this device. In my usage I like it to be responsive to my touches, sometimes I accidentally press the screen when I wanted to slide as you mentioned, but it happens to me on other devices to. I would also give some credit for this manifestation to you screen protector. I'm using the mate protector and it gives nice touch feeling over the screen on a minor cost of screen clarity and purity.

I have always had LG phones prior to this and never had this issue and I had plastic screen protectors on them. I have a tempered glass protector on this one. On this phone, I have to start the slide in the air before I touch the screen so the slide is in effect as I land on the screen in order for it to record as a slide and not a tap. Furthermore, on the YouTube app I have to make sure where I land on the screen even then. If you land on the video or near it, it will play the video instead of scrolling up. So far since the cache wipe, I don't seem to be experiencing the problem. As I side note, I just got the phone new a week ago and this is my 1st cache wipe.
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.
