I've been experiencing an issue with the Home button since the day I got the device.
A few times the Recent Applications screen has popped up seemingly on its own, while I was in the middle of doing something else. At first I thought it was just a software glitch and carried on. The haptic feedback pulses twice quickly. The backlight of the Home button turns off, the backlights for the Back, Menu and Search buttons stay on, the Back, Menu, Search and Home buttons no longer respond to touch or generate haptic feedback, essentially paralyzed. It remains this way for approximately nine seconds before the Home button lights up again and the all of the shortcut buttons become responsive again, otherwise the only way to get out of the Recent Applications screen is to either cycle the power button and unlock the screen, or select one of the recent applications.
I have figured out how to reproduce this problem by pressing around with the very tip of my thumb along the seam where the glass and plastic lip meet with a little more pressure than normally necessary to register a touch. I am careful to avoid touching the normal hot zone for any button. I start from the far left corner under the search button, and make my way towards the home button little by little. Somewhere between the Menu and Search buttons when I release my thumb after pressing firmly, the haptic feedback pulses twice and the issue occurs. I can reproduce this issue anywhere along the edge on the bottom right half of the phone and about 1" up the right side of the phone, far from the Home button.
I suspect there is something wrong with the capacitive layer of my screen.
Please see if you can reproduce this or something similar on your phone, just bear in mind that you will need to press firmly (not too hard but not soft).
The unfortunate thing about this problem is that it can be activated inadvertently while gripping the phone during normal operation, interrupting whatever you are doing for the time it takes to resolve itself.
This is literally the only issue I've had with the phone in the week I've owned it and I am considering whether or not I want to play russian roulette with exchange units (and other issues like bad screens and bad weak back buttons) because everything else seems to be perfect.

Same thing happens with me on the swap unit I got today. Bummed like no other.
Tried replicating this with my device with (thankfully) no results.
one and one... I wonder how many other phones are affected then, and how many people have it but haven't noticed yet, e.g.; "you're holding it wrong".
Hm. Just tried to replicate this on my Nexus S, no issues.
Mine did the same thing at least twice a day. However, it has not happened again since the GRH78 update. (Knock on wood).
Have your received the update?
This just happened to me for the first time about an hour ago. I have the new update too, sadly.
Yes I have the update.
I can't replicate this problem, but nonetheless, it still happens.
I have this same problem with my back button. I can't replicate it but it just randomly happens to me. I have the update and I also tried using Paul's Tom and it still happens.

This happens with my back button.

happens to mine too, also the home button. doesn't bother me too much, though. and I also have the update.
I had something even weirder tonight.
I did a factory reset, then proceeded to install everything back on when I noticed that my home key wasn't doing its job at all. Still had the haptic feedback so the input was received, but it did absolutely nothing. So I did another factory reset and that seemed to have cured the problem. My home button is working again (but i still have the other problem from time to time)
Had it happen again inadvertently today, if you notice from my video the spot where it can be activated next to the Maps icon also happens to be conveniently where your finger ends up when swiping to unlock. I was holding the phone one handed and unlocking with my thumb and it triggered the problem. Might try for an exchange this week. It shouldn't behave this way.
For those of you who are experiencing it with your Back button, does the backlight turn off for 9 seconds on your Back button?
I don't know everything about how the hardware works but I'm guessing that there is some kind of short, the controller for the capacitive layer gets confused and resets. Could explain why it takes the same amount of time to come back to normal every time. It also seems like it might be related to case/screen flex, where pressing on a part of the case bends the capacitive layer just enough to short the circuit.
This issue came on my two days old Nexus S too, but with the back button. It has happened two times now. I think that's a software issue that come along with Gingerbread. It's something like it registering a touch and sometimes the OS think it was the buttons that were pressed...

Does your back button black out for ~9 seconds?
I haven't had any button issues whatsoever since I got mine on the 24th.
No, more like two seconds.

Here's a new video shot today showing the issue occurring with only normal light touching:

Also last night it happened while I was inserting a cable into the headphone jack.
The touchscreen on the Defy seems a little over sensible .. i can press keys without actually touching the screen (same goes for the touch panel buttons)
Can anyone help me find a way to calibrate it ? I get a lot of accidental button touches.

You might get flame posting on wrong section.
But, capacitive touch screen doesn't require calibrate.
Your body / Phone build up statics..
For your part, wash your hand often or touch anything grounded.
For your phone, you could try wipe it w/ wet towel.
Why get flamed ? i wanted a software fix not hardware, i keep both my hands and the phone clean all day. And i know it can be fixed because i had the same problem on a iphone android port... In iOS the touchscreen was fine but in android i could get it activated even 3mm off of screen so it's definetly the way the software uses the screen.
Hi, I have a Samsung Infuse that I have set up with https://play.google.com/store/apps/details?id=name.kunes.android.launcher.activity&hl=en for my elderly Mom who has trouble with overly technical things.
Anyways, I flash CyanogenMOD as the sub ROM.
I'm wondering, have there been any advancements in the capacitive button backlighting lately? Last time I refreshed her phone, it was still only working with the stupidness where the always-on mod worked, but the lights would not turn on until you pressed a button first. Then the light would come on and stay on until the phone was put back to sleep again.
I hate this, she hates this. Has this mod been improved lately?
As far as cyanogemod goes, only cm10.2 has duration control for the backlight on the capacitive buttons. Cm11 will have a button section on the next build whenever that will make it out.

Thanks. But does it work the way I'm asking about? Such as the moment you bring the phone out of sleep, the capacitive buttons light up immediately. Without you needing to touch the buttons first.
And then stay on until phone is turned off again.
Anyone?!
Hi,
I just noticed a weird behaviour these days on my OPO.
The Home and Menu capacitive buttons work less and less.
It's not rom related. After two or three days with this weird behaviour on my daily runner Slimsaber MM, I decided to return 100% stock on COS 12.1 YOG4PAS3JL and it still happens.
So what's happening?
If I touch the buttons, they light up, but don't do anything. For example, when in an app, touching the home button won't bring me back to the launcher.
Menu touch is behaving the same.
Anyone faced this issue?
I confirm that my screen is perfectly clean and has no cracks (+ protected by a tempered glass).
Plus my phone is into a protection case and has no scratches.
Thanks for your help.

I think the capacitive buttons are part of the display... They probably are going bad if you can't fix it by flashing different ROMs. If I were you, I'd start using the onscreen nav bar. Its far superior to hardware buttons IMHO.

Thanks for the tip but I really don't like the nav bar. But yeah, I fear there is a display issue.
Think I'll let it go until it does not respond anymore and then buy a new screen.
Thanks
the recent key backlit is brighter than the back key in all situation I am asking if any one else has this ?
Now that you mentioned, my back key is slightly brighter than recent key.
Thankfully, I don't have this issue on my U11, but I have it on the HTC 10. It is NOT normal & unfortunately the local HTC service did not consider it as a problem! It is probably because the LED for the buttons on the back not glued to the display glass at the same level.
I don't think it is a flaw tbh
but just wanted to know if it is only my unit that has this issue
I do experience this. I put my phone into water (for less than 1 minute) and now capacitive buttons aren't responsive anymore. They turn on only when I touch the fingerprint (when phone's off) and the back button is less brighter.
