I am not going to pretend to understand why this worked, as many have pointed out, you can see the symptoms while in the key test... I started seeing this problem when I flashed LeeDroid v2.2. It was annoying to say the least, so I did a full wipe when LeeDroid 3.0 came out, and installed that fresh. Since doing that, I have NOT seen this issue reappear, and have subsequently upgraded to LeeDroid Kernel v3.1 without wiping.

I don't understand why my problem went away, but I think it is tied to Kernel. I am not sure, but it would seem that even though you're in CWM, you're still using the Linux Kernel (which is responsible for interpreting key presses).. If CWM IS NOT using the currently installed Kernel, then perhaps the Kernel they ARE using is suffering from the same flaw. In either case, flashing LeeDroid Kernel v3.1 has gotten rid of this problem for me. Hope this helps...
[HTC Sensation] Master&Slave™:
this problem persists even in CM7
[HTC Sensation] JMUT:
Someone previously speculated that the code that interprets the keypresses may have been updated with the 2.3.4 OTA update and likely downgrading that specific software is not part of the RUU install process. That being said, I'm getting so frustrated with this problem I'm seriously considering sending in for service.
[HTC Sensation] chieloz86:
i have try it.. and for now it works...
[HTC Sensation] f3nd3r:
How do you disable it?
[HTC Sensation] chieloz86:
Settings -> sound -> haptic feedback

I'm using dutch interface so i hope it's the good translation
[HTC Sensation] picachux:
Mine was already disabled, Enabled and it seems to have helped so far. Will post back after a day of usage to see if it holds up.
[HTC Sensation] ShinySideUpAZ:
Home menu -> Settings -> Sound Settings -> Vibrate Feedback
[HTC Sensation] craigspc:
Perhaps this is a really stupid suggestion, but I'll give it a go anyway...

Don't some apps like Widget Locker (?) let you manually change the button used to wake the phone? If so, couldn't an app like this help eliminate the possibility of a faulty power button? For example, if you changed the 'soft on' feature from the power button to the volume rocker?

Apologies if I'm completely missunderstanding the problem you guys are experiencing. It was just a thought...

[HTC Sensation] Phily757:
I've got exactly the same problem with waking up the device and the "double" click in recovery, using a 2.3.4 ROM.

But there is another big problem i have and i don't know if it's related to the power button issue. My Device turns itself off few times a day (e.g. while calling someone)

And it DOESN'T restart on its own, thats very odd to me! :confused:

Does anyone else have this problem, too??
[HTC Sensation] PygoShlee:
yep get the same thing. Is bloody annoying whilst trying to flash roms and just navigating recovery in general.
[HTC Sensation] :
Same thing here, not just that, mine go refresh the whole homepage, my saved playlist gone, my saved location gone, my saved photo album gone.

Hmm...
[HTC Sensation] EniHS:
I got my Sensation from warranty service and, like I said, it was hardware issue. They have replaced the button and now everything is ok.
[HTC Sensation] Master&Slave™:
Thats a kernel issue my friend...how much are u overclocked if you are?....try reflashing your custom kernel if your on one...is your phone hot when it restarts?...if so then thats a safety precaution to allow cooling

---------- Post added at 11:16 AM ---------- Previous post was at 11:13 AM ----------

It is not a hardware issue, in your case it may have been but if u have read these post correctly, you would have realized that majority of the people here got this issue after updating the SOFTWARE....

:eek::eek::eek::eek:
[HTC Sensation] ArcticWolf91:
Did you have it replaced by Tmobile? If so did they send you a replacement phone AND batter cover?
[HTC Sensation] knagl:
Hi, that's me. Weeks after upgrading to 2.3.4, I've started getting this issue on a more consistent basis (random screenshots when I press home, and occasional double-clicks of the power button when I try to wake or lock the phone). I did not have the problem initially, but as I posted earlier in this thread, I'm not a heavy user, etiher.

I believe now that my hardware (either the button itself inside the phone, or the button on the back cover that presses the button inside the phone) has finally degraded to the point that I'm getting impacted with the issue, too.

Has anyone confirmed with HTC that they're aware that this is a widespread issue and that they're working to update the code?
[HTC Sensation] Phily757:
No, it's not. I know what i'm doing ;) It wasn't overclocked!

I reflashed the Stock RUU, made it back to S-ON changed CID back, and the phone still shuts down few times a day. I will return it to HTC, let's hope they can fix it ;)
[HTC Sensation] f3nd3r:
For those of you on Vodafone UK, it is worthwhile posting on this thread http://forum.vodafone.co.uk/t5/HTC-Sensation/Power-button-problem-since-update/td-p/851753

A support rep said if they can get 10 examples of the problem, along with the firmware version, they will raise it with their support team. This is probably also worth doing even if you are not on Vodafone as it could push HTC to review the problem a lot quicker.
[HTC Sensation] anarchyuk:
I have started getting this issue now... it doesn't take screen shots just its like its being pressed twice sometimes and flicked on and back off. and sometimes only the led lights flash...

defo a hardware issue...the screen shot thing is just something that happening because the power button is used for this screen shot feature..
[HTC Sensation] ArcticWolf91:
I'm having the same problem too. I'm not rooted, and running stock 2.3.4. Its a really annoying problem. I hope it's software and not hardware related, but I'm kinda thinking it's hardware...
[HTC Sensation] slick007:
I also have this problem since a few week's ago but I thought is was a rom failure or that my power button was stucked. In the last week-end I had some free time and I looked over my case, specialy the power button and everything works as it should. After that I did a little research and I found this thread !

I am a little disapointed about this problem and my disapoint is bigger that we don't even know what is causing it: software or hardware ?

I don't remember exactly when I first encountered this problem and I cannot tell exactly what happened :(

I'm sad because my phone runs very very smooth but sometime is taking screenshot's or is not locking / unlocking at the first button press !!

*** the phone is rooted and I'm running insertcoin right now !
[HTC Sensation] familyhousing:
This is not a hardware issue. Everyone who has this problem is (or has previously been) upgraded to 2.3.4

It's strange that thrbproblem still exists after downgrading the ROM. Is there any possibility that new firmware has been flashed to some hardware component on the device?
[HTC Sensation] robertk2:
Also I am suffering from this problem. Been armwrestling with HTC Support for a while now but even the escalation teams only suggested solution is factory resetting the phone. And, they claim never to have heard of this problem before. *sigh*.

Anyway. If I remove the cover and use the actual powerbutton (not the silvery one) it will never glitch. Sounds likely to be hardware to me. Perhaps the construction of the cover is simply flawed?
[HTC Sensation] slick007:
I also noticed that without the cover the phone works without a problem.

I will check again, maybe it was just the period when the phone actualy worked well (because sometimes I don't have the problem and it randomly reapear) !!
[HTC Sensation] jrslims67:
power button issue

Guys,

It's definitely a hardware issue on the cover. The silver button is attached to the cover via a leaf spring. Over time and many presses, this spring weakens. There is also a fair amount of space between the silver button and the actual power button on the main body of the Sensation. It really is a poor design on HTC's part. I have thought about sticking a spacer to raise the silver button back up and to return to a more positive response. As of now, my silver button is pushed in so much that it is almost flush with the cover!
[HTC Sensation] slick007:
I don't know if it's hardware issue and if it is, is not because ot the backcover button.

I have right now in front of me 2 sensation phone's, mine which has the issue and another one who works perfect. I changed the backcover and the result is the samne, mine with glitch and the second one with my cover is working normal.

so i think is a software issue !!
[HTC Sensation] ArcticWolf91:
Try it and report back to us! :D
[HTC Sensation] robertk2:
Ok. I created a spacer now. Using a cut-out small stack of postit notes. First I placed on top of the inside-button but there was no difference at all, rather worse, the screen took 5-8 clicks to turn off... regardless of how many sheets I took away or added.

Then I cut the spacer in half and placed it to the left of the button. That raises the silver button and gives a better space between the cover and button itself. And now the screen turns off four times out of five. So there is a definite difference I'd say. Still not good but perhaps livable until someone fixes this for real.

My theory is that the silver button and the "real" button are too close together caused by wear and tear, so a click could make it "stick" and the phone would start registering multiple clicks. Now, when the silver button is raised it sure seems to work better.
[HTC Sensation] anarchyuk:
I have 2 different revision covers both do the same, the little power button circuit board looks weak to me, stuffed some rolled up paper inside the cover because if you look at the inside.of the power button it has a little black plastic bracket that's suppused to make.contact with the link on the.power circuit board. My phone.is more responsive when turning the screen off and on now..
[HTC Sensation] slick007:
can you provide us some photos ?
[HTC Sensation] familyhousing:
I am also finding that this problem is less likely to occur after the phone has been restarted. Right now, I cannot replicate the problem at all - I have tried pressing the button in different ways (quick press, long-press, light-press,from the sides, centred, etc). Something triggers this in the software.

Also, although not tested myself, many users report that disabling haptics fixes the problem. How can this be explained as a hardware defect?
[HTC Sensation] robertk2:
I tried this. No difference at all for me..

-----------------------

Here's a pic of my professional (yellow) spacer btw :).
[HTC Sensation] slick007:
robertk2 ..nice work, but just like I said, I don't think it's a hardware problem.

how do you explain that I changed the backcover and mine on the other phone is not makeing any problems, but the one from the good phone put on my phone is doing the same annoing problem ??

it realy started to piss me off ... I don't wanna change this phone but for sure I will do it if the problem will not be solved on a short time !!

n.b. I also spoked with badnewz and I put 2.3.4 ruu version and did s-off again and a clean install of the rom, but the same thing happened.

I dont't like to do such experiments with my time / my money and my nervs !!

If it was a rom related problem, it was normal, because the dev's are doing this job for free, but when it's htc's fault, I realy don't like it !!
[HTC Sensation] robertk2:
I really can't explain anything regarding this crappy problem. It's seriously pissing me off too rest assured.. perhaps it's related not to the cover but to the power button on the phone itself? Bah, who knows.

I know only one thing. And that is that the spacer improved the behaviour of my phone.
[HTC Sensation] ShinySideUpAZ:
I spoke to this point earlier in the thread. http://xdaforums.com/showpost.php?p=17162436&postcount=52
[HTC Sensation] Master&Slave™:
I personally dont know what all the winking is for, as if your saying, ok so you dont know what your talking about...but i sure as hell know what u described can be all listed as kernel issues. At the end of the day since you did all of that, it seems as if u just has a defective device.
[HTC Sensation] fryrice8850:
Idk this is getting annoying, it seems to happen after the upgrade that HTC sent out. I'm also right now running insertcoin custom Tom and it has the same issue. Sounds like a hardware issue but its hard to tell. Also the phone loves taking random screen shots now
[HTC Sensation] predator21:
i too have this with second sensation....

Edit : after i remove the back cover all works perfect....even key test but after putting it bk..it troubles...i guess that silver button problem
[HTC Sensation] familyhousing:
Power button issue has gone away for today but the Phone powered itself off in my pocket today - first time since I bought it at launch.

All these symptoms seem related.
[HTC Sensation] mathyou9:
For me, taking the cover off made the issue less noticable (must be something about directly pushing the button) but I still experienced instances of double-clicks. Doing the key test showed instances of double-clicks, as well, with the cover off.

With the cover off, it definitely is not as often as when pressing the button through the cover, but it was still present nonetheless.
[HTC Sensation] anarchyuk:
whats all of your experiences of pressing the button really quickly and not very hard? does this improve the issues?

I have changed my ril to a matching one for my radio and the rom I am using as the issue didnt change when i went to cm7 alpha 3.. so i done a restore from sd to revolution 3.1.1 matched the correct radio and ril and the problem still only happening on hard presses and not when the button is lightly touched.

I dont see how this has anything to do with the 2.3.4 as my sensation came back repaired from htc with 2.3.4 and it didnt have the issue on return. only secured about 2 days ago..
[HTC Sensation] EniHS:
IT IS hardware issue. Warranty service confirmed it to me. They did replace the button parts in the phone (not the silver one on the cover - so switching covers does not change anything).

You say that people were experiencing this after upgrading to 2.3.4... Everyone is now running at least 2.3.4! So how is it a reason? And, I got my phone replaced with 2.3.4 and the issue is gone...

It is just poor design of the button, that eventually weakens and starts getting multiple presses.

Don't wait for software fix beacues it will never be. Back to S-ON and send to warranty service.
[HTC Sensation] anarchyuk:
All I have to do now is find a three uk stock rom

I have changed my cid to the htc stock one and put a 2.3.4 rom on and set s-on.. so if they ask I will just say job on its stock. the power button doesnt work fix it. the are picking it up tomorrow... bloody thing since i put it back to stock is now taking screen shots all the time
[HTC Sensation] f3nd3r:
To all those sending theirs in for repair. If it is a hardware issue, it is a hardware defect and there is no point in sending it in for a repair only for it to happen again in a few months. Surely it's better to put it on ebay and get a completely different phone without these kinds of defects.
[HTC Sensation] anarchyuk:
I would hope hardware revisions on parts might stop these issues. i know the back covers have had multiple revisions... ya never know!!
[HTC Sensation] ArcticWolf91:
Ok, so I'm pretty convinced that it's a hardware problem. Ever since I started using a case the problem is almost gone (still happens but now it is very rare). I believe the reason is that the case makes me push the button a little harder than without.

Robert how did you make that little spacer?
[HTC Sensation] robertk2:
I cut it out from a stack of postits simply. The quite weak glue already existing on the lowest sheet is enough to keep it in place also.

Had this for two days now and haven't had a single screenshot taken and the screen turns off nicely every time (with one or two exceptions). I am now absolutely certain this is hardware-related and nothing else. No more problems here! Very happy :)

best, Robert

guys chk out a small fix here

This does not explain how most people here have noticed the problem after a SOFTWARE update to 2.3.4.
[HTC Sensation] abowmedia:
Yea glad to see its not just me. I'm having the power button issue too, but the one that's driving me up the f'n wall is the Screenshot problem. I'd say at least 20 - 30 times a day I try to turn the phone on and press something, and it starts taking screenshots instead until I power off and on again. This phone has been exceptionally frustrating. I came from Nexus One, which the touch screen issues were irritating, but I was able to get over that in a matter of weeks and never though twice about it. The Sensation on the other hand has been an uphill nightmare. Between Sense UI reload, unprompted full reboots, Faulty touch screen, power button tweaking after the 2.3.4 update, and the screenshot issue, i'm ready to pitch this thing into the ocean and forget about it.

This was my first, and absolute last time picking up a phone with a manufucturer skin on it. I need to root the damn thing but haven't been able to find a way to do it with my Mac. (not purchasing windows to bootcamp it, and dont have access to a PC anywhere). Oh well.
[HTC Sensation] f3nd3r:
You can root with Linux which is free.
[HTC Sensation] jrslims67:
Hey robertk2, thanks for creating a spacer - that is exactly what I had in mind, but I haven't had the time to make one since my post. I was thinking about actually using a small plastic piece, but I guess Post-Its work too.

Good job!

Right now, I have to push my power button on the left side to make contact with the black plastic click piece on the main body itself. What would really be the suck is if the click piece weakens over time (which appears to be the case). Definitely a hardware issue and would need to be sent back for repairs :-/

***Addendum***

Just tried the post-it approach since I had some laying in front of me on my office desk. I used about 3-4 small rectangles to cover the detent/clicky part on the main body. My power button height is back to when I got it new - 1 week before T-mo started selling the S4G. It's a more stout, positive click.

The screenshot problem is probably software related - I never had that problem though, mine was just a mushy sunken power button. Me detects two separate problems.
[HTC Sensation] predator21:
it doe my frnd... its a mixed problem smtime triggered by software and smtime by hardware...mine got hardware triggered and is now fixed....
[HTC Sensation] familyhousing:
I haven't seen the problem for two days now. Has anyone else seen the problem disappear recently? I have made no changes, other than market app updates.

Edit: thinking about it, I haven't seen the problem since my Phone randomly shut itself down in my pocket earlier this week. Is it possible that simply leaving the device powered off completely for an extended period fixes the problem. Perhaps someone with the problem could try removing the battery for an hour or so.
[HTC Sensation] chowster:
I just received my phone back from warranty yesterday. I thought the problem had been fixed. I used it for about 2-3 hours and had no problems. This morning the problem has reoccurred again. It’s been booked in for another repair. I am really not happy. We will see what happens when I get it back for a second time...
[HTC Sensation] F.3.A.R:
I never did get the power button problem to return on mine, so it seems I permanently fixed it with software/re-flashing somehow (as per my earlier post). There's no point arguing over whether it's hardware/software, I think it's both. They just confusingly have the same symptoms, unlikely as that seems.

Last week though, I noticed an update for Adobe Flash Player in Market, so I duly updated. Literally seconds later, the home button started taking screenshots again. Uninstalled the Flash update, and it was OK again. I tried this a few times and it seemed to consistently break/fix it. The latest (past couple of days) update to Flash seems OK though.

Might be worth somebody else with the camera/home button problem trying uninstalling Flash player to see if it helps. I know it doesn't seem like a likely cause, but I thought I'd share my personal experience.
[HTC Sensation] f3nd3r:
This just re-enforces it being a software issue.
[HTC Sensation] robertk2:
Then please explain why all symptoms of this disappeared the moment I inserted the spacer described earlier in this thread?

Mr F.3.A.R is probably right.. this can be both, however strange that seems!
[HTC Sensation] Kyrasym:
Whoa...dood! This really seemed to work! I will monitor this to see if it comes back man.

Edit: NOPE...the problem is back!!!!
[HTC Sensation] daksh_jay:
i can too confirm that this irritating problem started exactly after i installed the update. because i had gone to HBOOT to check the hboot version for revolutionary before the update and that was the first time, so i roamed around a bit and the power button worked fine. and then the update came along and i performed the update.

and from then on it was just a mess-up of home-button screen shots and power button malfunctioning.

so i S-OFFed it and flashed revolution hd by mike1986 and the freekn problem still persists!

i, for one, am convinced its a software-initiated problem atleast. but still clueless about why the power button malfunctions in HBOOT too!
[HTC Sensation] f3nd3r:
As suggested HBOOT could be using the same kernel as the update. It might be a bug in the kernel.
[HTC Sensation] idriz:
Removing adobe flash player solved my problem with the (strange power button and snapshot taking home button) hehe
