[Q] It Anyone Else Having Touch Button Problems?

Is anyone else experiencing the occasional mixup when hitting the back button? As not always, but many times regardless of the application thats open, I'll hit the back button and the search will come up and I wondering whether thats a common problem or a sensor in my phone is defective and I need to exchange it for a new one...
Thanks in advance

im having a different problem with the buttons. a lot of times my first touch wont register and i have to press it multiple times for it to be recognized.

I've noticed that my touch buttons aren't as sensitive as the touchscreen, and that I need to use a lot of pressure to get them to activate on the first try.

not alone there.. same issue here. I have a clear screen protector over them though.. though it shouldn't be a problem.. I've had the issue even before the protector so..

I have a problem with the back button too, not the other ones. However, when I press a spot a little to the left of the back button and not exactly over the button, it seems to register the press correctly.

I have found that the buttons just do not like any other finger than the index finger try to use the thumb and it will go to search or do nothing.I also returned my first phone as the buttons were terrible 80 percent of the time they would not work.So there maybe be a flaw in some of the phones as this one works fine even with the phantom skins on.The first phone would not even register a response with the skin on.

The buttons on the Captivate suck.
Buttons, as a construct, are well known.
The functional priority of the button is not a mystery and hasn't been for 100 years.
It has to click or otherwise give the user an indication the button has been pressed far enough to take effect.
It has to be tacticle. You have to have some way of knowing that your finger is on the button before you press it.
You have to have some leverage to put enough force on the button to make it move.
It has to be about the size of a finger tip.
It has to be visible. If you can't see it you can't press it.
It has to be different than other buttons that are millimeters from it.
It has to react the first time you press it, or you will naturally press it again, achieving unwanted results.
In all of the above, the Captivate fails.
The T-Mobile Galaxy has more a lot more real estate below the buttons to allow your fingers to get on to them, and a raised ridge on the rear surface of the phone exactly to give your other fingers something to grip against to increase aim and pressure.
But the Captivate has a nice lot of space at the top OH YEAH!

The only problem I have with the buttons is that I can't see them in a dark room

I'm getting something similar. Sometimes when I hit the home button the search button blinks as if I had pressed it, then brings up the search screen. On my first captivate (mfg. date 7/16) sometimes it would happen once out of every hundred presses and sometimes it would happen 3 out of 5, very inconsistent. I traded that one in for one with a later manufacturing date (8/10), and my new one does it too but maybe only 1 out of every 100-200 presses. The fact that the search button blinks makes me think it's some kind of short/hardware issue. The back button has only triggered a search for me once, and that was on my first phone.

So this is a hardware issue or a software issue?
My back button on my phone must be pressed 4-5 times sometimes before it will register. The phone did not have the issue when I got it, and a friend of mine who has the Captivate as well does not have this issue.
It may be my imagination, but the phone seems to register touches better after I run a task killer or after restarting the phone, but tends to have issues when multiple apps are up and running.

I was having a button problem as well but fixed it by upgrading to JH3. h t t p://forum.xda-developers.com/showthread.php?t=767666
Your mileage may vary but it worked for me.

May be my imagination, but it seemed to be more isolated to back button on JH3 than JF6 on my machine. My perception is that if I take an additional half-second pause before pushing back button it registers more often. Do not believe it is hardware though. I believe that your home page(button), settings (button), and search(button) all reference something that resides in permanent memory(ROM) whereas the back(button) is trying to recall something that is in temporary memory (RAM) and possibly similar to lag issues may be related to Samsungs somewhat proprietary file allocation system. I am by no means computer literate enough to ponder concept any deeper than just mentioned.

I was having a problem with pushing the home button and the search would come up. I took it to a AT&T store and because I was still in the first 30 days they swapped it out for me.

i'm having a completely different issue with my touch buttons. my back button will register multiple button presses even when i'm nowhere near it. it's quite frustrating to be in the middle of an app and all of a sudden the back button goes off 3 or 4 times and gets you back to the home screen. i've tried searching the forums for some resolution or to see if someone else has had this, but not yet.
Edit: I must not have searched thoroughly enough, found another thread on this issue. http://forum.xda-developers.com/showthread.php?t=858873&highlight=back+button+issue&page=2

HD7 build quality annoyances.

power button: Too recessed and flat, to the point where I now have to use my fingernail to power on the device.
volume button: Flimsy to the point where I can literally slide it up and down. I can also hear it jingle when the device vibrates.
Backcover Flimsy, moves around too much and is never tightly secured.
hardware: When I unplug my device from the charger and the screen is getting ready to time out, it flashes green, then times out... (this looks like it's going to create bigger issues down the road)

Power button: 1 in 20 HD7's I have exhibited the behavior you mention. It went away however. I would advise against using your fingernails if at all possible.
Volume Button: Again, 1 in 20 have this, and unfortunately it's the one I carry around. Two other HD7's I personally used did not have this.
I'd try to get it replaced if I were you.

I'm 2 for 2 on the first two annoyances (power and volume button).
I'm getting it replaced again (for the third time) tomorrow morning. I've also noticed these problems with the store models at various T-Mobile stores.
If I have the same problem with my third device, I'm returning it and getting my refund. Omnia 7, here I come.

Hmmm... I don't care much for the power button placement, but I haven't seen any of the other things you mentioned.

regarding issue #1, how did the problem go away? did some mechanism inside shift causing the power button to pop out more? just wondering?
i also have the loose battery cover. very annoying.
also about the screen... havent seen this mentioned before. i have a slight gap at the left and right edges of the screen where it meets the chrome-ish border. its pretty easy for particles to get stuck in there. compared to the hd2, this gap is pretty noticeable.

I thought I was the only one with these issues lol, figured the recessed power button was just a design oversight
@jimbonics: just wondering, but why do you advise against using your fingernail?

Seriously? I checked a batch of HD7 in malaysia, and exceptionally, all of them had this issue. You're just so lucky you dont have it

Maybe because of this ?

Thanks Shu and daaango.
I knew I wasn't crazy in thinking this was an issue only I was experiencing.
I've also read several phone reviews, and a lot of the reviewers mentioned about the power button being recessed and stating frustration waking up the device.
I don't know how HTC can fluff up something so important. I mean, what good is a product if you can't power it on; wake it up? One would think they would put emphasis on having a solid foundation on the power button.

Melcali: Yeah, on one phone the power button managed to become flushed, to the point the user had to use their fingernail (even though i found it easy to turn on with the flat of my finger, almost like it was capacitive). However, next day it had 'popped out' a bit and had become less recessed and hasn't been a problem for him since.
daango: In addition to what Shu posted, using your fingernail is likely going to cause you to press the button in harder than it needs to be, which would likely cause the button to be crammed in more and more over time. If it can't be prevented, it can't, I'm just advising against it.

I've got two unopened spares. I'm going to crack them open and see if the volume button jiggles.

Ah, thanks shu and jimbonics for explaining that
Honestly, I don't think it can be helped. Maybe my fingers are too round or something, but using my fingernail seems like the only option right now. I might try adding layers of tape on the button so its easier to press but idk yet... it might take away from the aesthetics

All five units I've come across so far -- my defective original (corrupted memory), my current one, a second defective one (also corrupted memory), its replacement, and an in-store demo phone -- have the same issues:
Recessed power button
Very difficult to press camera button (basically useless)
Loose volume rocker (the case opening is about 0.8 mm too long for the rocker, so it moves around)
Imperfect battery cover fit (the plastic cover flexes from the opening process, so usually doesn't fit perfectly)
Weak screen support in bottom-right (press a bit on the search key and you'll see waves on the LCD)
On the two that I've had long enough to use, the clear coat on the kickstand is flaking off, and the Windows Phone logo, which was barely visible to begin with, has almost completely faded away on one of them.
Kind of sad that HTC screwed up so badly given that the HD7 is a barely-modified HD2, which was among the best-built phones on the market.

wow, you have had a lot of problems. I'm still on my original hd7 since second week of november.
1. power button is slightly recessed, but no problems pushing it with my finger (not nail)
2. camera button does have some orange on it, but it functions properly.
3. volume buttons work fine, maybe a little slide to the rocker, but doesn't effect controls
4. no flaking of clearcoat, no wp7 logo coming off, no lcd discoloration no matter how hard I press on the search or back buttons.
5. Back cover fits properly. I haven't had much reason to pull it off after initial placement of sim card, thanks to phone not constantly freezing. There is a slight gap where the back cover meets the smaller cover.
What are you subjecting your phones to???
I agree the hd7 build quality might not be iphone, but it's holding up well for me. It's not like we have a lot of choices on t-mobile, the dvp has way more problems at this point.

amb9800 speaks the truth. I went through 3 different units that had defects to varying degrees. I had similar issues with the EVO as well. HTC are notorious for shoddy craftsmanship.

I have the same problems they started AFTER my 30 days .. So i havent tryed to go and change at my local T-Mobile!! Is there any loop in the contract or something that would let me change it for anither phone and pay difference/get a refund xD

have the same problems as the op

Power button failure

First off, I know there are multiple threads not only here on xda but elsewhere on the internet that describe other cases of Nexus One power button failures. I believe mine is different.
I suspect this has something to do with it being submerged in a cup of beer for a half a second a couple weeks back (never letting that person touch my phone again btw). It's very intermittent and has gotten progressively worse, to the point where I think it'll eventually die and at that point I'll need to turn the phone on some other way. I think somehow it is a "short" electrically inside the device. It can sit on my desk and randomly turn on and off by itself, as well as make the reboot/power off menu pop up, as if I'm holding down the power button. This makes using the phone extremely irritating, especially now, as the problem worsens. I can't do much in Recovery, at least CWM, because the power button either turns off the screen or goes to the previous menu. And while typing, the phone screen will either turn off, or the reboot menu will pop up, and I'll accidentally tap something else. Frustrating. My question is basically...is there a way to disable the power button without opening the device? I'm guessing probably not, but it's worth a shot...I purchased the phone in 04/2010, from a third party, and it's no longer under warranty. I was planning on waiting to get the Galaxy Nexus, and if not, the Samsung Galaxy S 4G. I've been dreading the day I need to retire my beloved Nexus One....and it looks like it's going to be sooner than I wanted.
Thanks for any replies.

Normally I would say there is probably still a little bit of water in the power button housing but since it was a few weeks back I doubt it. But I guess you could always try the bag of rice trick. If then I don't know and you may have to open it up :/

I had the same problem for about 5 months and it has sense sorted its self out without me doing anything. Now the power button functions 100% (knock on wood).
I had placed it top down in my cup holder while driving for 3 hours and had not noticed a bit of condensation from that mornings water glass. I got home, grabbed my phone, and noticed a wet spot on my pocket and my phone had water on the top. It was in the Case-mate case in my sig and I let it dry over night and it worked the next day after blow drying the inside. But a week later the power button was clicking on and off. That was the longest period of use my G1 has seen sense I bought my N1.
Some days it would go on for an hour+ and would wreck the battery life. I tried everything and was unable to find a way to disable the power button presses.
I did not open the phone even though it was a month out of warranty. My assumption is there was still some sort of moisture inside that was causing a short. Because you never had a warranty in the first place, I would say your best bet is to take it apart and let it sit in rice for at least a couple days.

[FIXED]: Phone Laying Flat, HOME/BACK are Non-Responsive

So you've played with changing button sensitivity, heard about perhaps removing the screen protector, but still don't get it?
I think I might.
Try this, let me know if you guys can confirm, then perhaps we need to send info to HTC?
Unlock your screen
Place your phone on a level surface so its curved back can rock back and forth.
Enter the app drawer, so pressing HOME will actually do something.
As gently as you can, steady the phone with one hand, and touch HOME (It should work)
Now, re-enter the app drawer and press quickly on your phone's HOME key. This will cause it to quickly rock back and forth a bit and shake.
Press the home key all you want, it shouldn't work... especially the more you bang on it.
Wait 10 seconds.
Steady your phone again, press HOME gently. It should work.
The theory? Something is programmed in the phone that if it detects rapid shaking, like maybe in a pocket or being handed back and forth during watching a video... to turn off the buttons to prevent undesired actions. BUT, the curved back of the phone naturally lets this motion occur so it's triggering when it shouldn't.
If you're particularly twitchy, maybe that can cause it from time to time while even in hand too?
SOLUTION:
Run calibration tool a few times until the symptom goes away. Try alternating between pressing more firmly or more softly to make a difference. Take care to center your fingers on the letters.
If you experience bad button behavior while phone is on a flat surface, re-calibrate:
SETTINGS->Language and Keyboard->HTC Sense Input->Advanced->Run Calibration Tool

I couldn't replicate this problem. The home button works as intended while being rocked. I also haven't found to have any button response issues that some encountered.

Heh, come on man... the phone has BOOM Sound, it was meant to be rocked, no?! :laugh:
Serious note though... yeah always have thought the buttons worked fine too and thought other people were crazy...
I lay it flat though casually press them, they go away and don't come back.

Also couldn't replicate it. Basically the home/back buttons work when they want to, which apparenlty is about 95% of the time. The other 5% is just purified annoyingness.
Allegedly HTC has fixed the button problem in 1.29.XXX.12 which so far has only rolled out to unbranded phones in Europe and Asia. However if you have the international phone you can install the newest Android Revolution ROM which is based on the .12 software. Everyone who has .12 seems to agree that the button sensitivity issue is gone.

Re-ran calibration tool pressing normally and it seems to have fixed it.
No amount of shaking or rapid pressing causes the phone to miss a button press.
This is with US Version of phone w/ screen protector.
If you experience bad button behavior while phone is on a flat surface, re-calibrate:

Unresponsive parts of screen?

Is anybody else experiencing unresponsive screen on some parts?
Couple of days ago I started having problems with letter "a". It wouldn't react unless I pressed it all the way at the left side of the key, which I attributed to being close to curve of the screen - if the phone was in my left hand then I pretty much punched it on the right spot every time, so I thought it had to be it. It's an ongoing thing.
But now I was making a video in Quik app, and in one of the screens the play/pause button is right at the place where the letter "a", and I found my self having to press the key like 10 times in a row before it reacted - on a couple of occasions. I doubt it's some sort of memory issue since this thing is a beast and no way a couple of pics in Quik app could make it unresponsive.
I am utterly crushed now, since I love this phone to death. I really hope it's not a defect :crying:
