Hi guys,
Few of the buttons on the hardware keyboard are not responding properly. Some require a hard press, some tend to write the character more than once when pressed. I suspect its dust disturbing the button press. I tried cleaning it by dis-assembling the phone, only to find that the keypad is just glued to the body from the outside (yes glued). Couldn't find any screws that i could remove to get the keypad out.
can you help me with this?
Thanks.
didi you manage to solve your issue? I'm having the same problem
I've had this problem as well, with certain keys showing up more then once when pressed.
Your best bet would be to downgrade and send your device into htc for repair.

HELP everyone! I'm having a problem with my TP2. Whenever I slide open the keyboard, the screen goes blank. Any ideas as to why this is happening? Thanks.
Perhaps the way you hold the TP2 while you are opening it is causing you to press the power button?
I had the opposite problem, sliding my keyboard shut would turn off the screen. Eventually sliding the keyboard shut would randomly reset my phone. Figuring it was a software conflict or registry mess up, I did a hard reset. The problem still continued, so I had to do a warranty exchange. So far so good on my refurbished phone.
Initially when pressing the back button on my desire, a large majority of the time, it would register it correctly (i.e. do the operation associated with the back button), irrespective of my finger placement as long as I apply a low amount of pressure.
Now, I find that a lot more key presses on the back button are lost. I have to press much more harder / deeper to improve the chance the keypress registers. This is the second time I've encountered this and the third hardware fault I've had:
Fault #1: headphone jack not working, music continues to play through speaker (repaired)
Fault #2: back button doesn't always register key presses (repaired)
Fault #3: back button doesn't always register key presses (going to have to be repaired again, sigh).
I've searched the forums but haven't found anyone else mentioning this problem. Has anyone else experienced this issue at all? Or have I got crummy luck and gotten an HTC Lemon?
I have the exact same thing. Only started recently though. It takes a hard press sometimes, and other times if I press hard it's like a double button push.
You aren't alone. Lol
Cheers rolfd. Least I know I don't have the "touch of death".
It's definitely fixable cos I've handed it in for repair and it's come back working. My concern is more if it continues to re-occur. Guess I'll have to wait and see...
You are not alone about this problem:

Both mine Menu and Back is not working properly. Got send it in for service and still havent get it back yet.
*Update* My phone got repaired.
Back button now works as expected. Fingers crossed it stays that way...
I'll try to be as thorough as I can describing my problem in hopes that some of the smarter people here can help me find some kind of solution or workaround:
I've recently gotten a used Desire Z. The few obvious things when I first got it were:
-Phone had obviously been opened at some point, and not put back together all that well.
-From certain hints I assume the touch screen has been replaced.
-It seemed to have a completely stock (stock HTC, that is) bootloader and ROM, Gingerbread.
-The screen response was mirrored in portrait (left touch gave response to the right). A Hard Reset fixed this.
-The capacitive buttons did not respond. No vibration either.
-The optical trackpad responded normally.
In an attempt to fix things, I went through downgrading and permarooting, then installed Gen.Y VisionX B4. No problems, everything went fine and according to the guides. I performed a full wipe before installing.
The ROM runs quite smoothly on my DZ.
However, I still don't have working capacative buttons. After remapping the trackpad-click to "Back" (just to be able to use it at all), I've tried to figure out how to get them working again.
I've seen mention of a fix in http://forum.xda-developers.com/showthread.php?t=847824 , but the file is no longer available on multiupload.
I've tried installing Enhanced_Keymaps_r3-Andromadus_Audacity.zip, which did not make the buttons work.
I've tried changing build.prop to show the Nexus-like software keys on the bottom of the screen (qemu.hw.mainkeys=0) but this didn't produce any effect at all (is this because of htc sense?).
In other words, I have a Desire Z that is hampered by the capacitive buttons not working, and no real idea how to fix it.
I've opened the screen portion of the phone and checked the cable connections, but they all seem fine.
I am at a loss.
Hopefully, someone here will laugh at my n00bness and point me to a simple solution.
Anyone? Please?
it is very possible it is hardware, if the digitizer is new and working all besides the soft keys then my best guess is the ribbion or the keypad is bad, if your familiar opening it up, as it appears you are its a simple fix and cost about 15$ on ebay or amazon.
it is possible the main flex is bad, but my bet is the keypad

Thanks guys, that's the kind of info I was hoping for.
What feels strange is that the entire touchscreen is working otherwise (to the point where touching the soft buttons will activate the function directly above it on the screen) and if the flex for the buttons where shot, I can't understand why the optical trackpad is working, as it is on the same flex...
But I guess it's possible to keep guessing forever.
Does anyone know why the on-screen softkeys that come with ICS won't work? Does sense override that?
Hello,
my volume up button does not work, but i think i know what the Problem is. But i need help by identifying some components.
The board on the picture is not the broken board, but one from the same revision.
The red mark shows the position of the broken parts.
Thank you!
My phone also have this kind of problem, the volume-up button is hard to be push but there is no broken thing.
More pictures
I made one more Picture,
and i think that could be some kind of diodes...
Hello there! A friend of mine gave me her Galaxy S4 mini GT-9195 LaFleur (pink one). She was going to throw it away as she dropped it in half a glass of water. Apparently, some water got into the bottom of the phone and got the Home button stuck. As a result, the phone permanently gets the hardware Home key signal and is almost entirely unuseable. I managed to get past the PIN-code screen by entering the PIN while manually holding the Home button, but that's about it.
I also managed to root it with the intention to install CM which features disabling the hardware keys and using on-screen keys, but I wouldn't be able to get to the menu to disable the keys. I've also found other methods, but they involve editing files on the phone itself, which is impossible because of the Home key being pressed about 3x per second.
So my question is: is there a file I could flash to resolve this issue and disable the home button or disable all hardware keys? Or is there maybe a rom written with these keys being disabled by default, and on-screen keys?
Any other help or suggestions are of course also very welcome!!
Thanks!

None that I know of!
The key is probably malfunctioning because there is still moisture in there and it's shorting the switch out (or possibly it's now what is the salts etc left after the water evaporate). In first case put it in an airtight container with with the battery out & cover off & a lot of rice and leave for a week or two. If that doesn't work (better option I think) take the cover off and remove the back panel, take out the power board PCB and clean the contacts of the switch and ensure there is no moisture anywhere in the phone e.g. under chips etc. (also check other switches etc water may have condensed in other areas) (you can buy little phone tool set on ebay etc cheaply). Should then work normally ........:fingers-crossed:......

Thanks, but I've been able to solve it differently. The phone was kept in a airtight box with rice and anti-moisture silica for a few months, but the problem continued.
I noticed that after being locked a few times, SOMETIMES I was able to hold the home button, and then access the menus. I then managed to root it, add soft keys in build.prop and disable the home button in the generic.kl file in \system\usr\keylayout...
Problem solved! It's a functional phone again, without a hardware home button.

Oh right, so you managed to get in to root it etc. :good:
(yes rice doesn't always work as moisture can stay trapped in areas like the buttons contact pads underneath, I think. Even if dried out contaminates can remain that can short switch)
