[Q] Power Button Not Working

Hi guys,
I have a little problem where my phone's power button will not function in any way, long presses, short, almost embedding my thumb in it, all to no avail. This is doubly dissapointing as I have just installed the latest dexter plus patch to fix the problem. I still had the problem on the previous version and I thought a clean start may fix it. The only way I can get the screen on is to press the media play button! Which of course isn't doing anything on dexter.
Hunches:
I have been playing with a light sensor program and using a 3 second press to turn the phone off, I am only thinking this is related as when I re-installed then turned off the phone using a battery pull, that now the media gallery button will now not work at all, so that is a change.
Second, the power button is buggered. Seems unlikely as everthing feels normal, no big drops have occurred from heights, and the button is travelling in and out as usual.
I have also noticed that as soon as I re-insert a battery that the phone starts immediately, the M pops up as if it is already posting. So maybe it is stuck down?? Again, I don't think so, as the mechanism is working per usual.
If anyone can help it would be fantastic, you guys haven't let me down yet, and this thing is purring, but unfortunately I cannot use it lol. Just my luck.
Thanks in advance

another thing, still not solved
Another thing is happening, the phone screen turns on "after" pressing the power button, it may be once or a few times, and then pressing the gallery button.?!?!
Also, at random times it plays a podcast on my phone, the exact same podcast, and from the start, though the duration may be a few seconds then repeat, or it may go for ages, its quite a rude podcast too which has caused me to throw my phone under the car seat to shut it up when people have been trying to talk to me, as you can imagine its quite embarassing.
There are no services or apps running that I can find related to music, it may happen after pressing the camera button, or opening a website.
It is still going really fast though. And I have also reinstalled the light sensor program so I can turn it on and off without causing damage to the power button.
Thanks again everyone.

please clarify

sure, so the only way I can get the screen to turn back on, after turning off as per display power saving preferences, is by pressing the power button, maybe a couple of times, then following that up by pressing the gallery button next to the shutter button, pressing the gallery button doesn't seem to be working to turn the screen on now, but this combo is.
I hope that helped.
Cheers.
EDIT:::
The gallery button alone is working again. sorry guys.

You might just want to reflash it to stock to see if this resolves the problem.

Yeah I think I may have to.
Before I do., I was reading a post on a different forum where another person was having a similar issue. They seemed to solve the problem by using rom manager to boot to a manual restore menu where there was a button tester section, after using it the power button worked for them. I tried but after resetting it displayed a triangle graphic then rebooted.
Is there any way to do this with our open recovery program or any other utility to test the functionality or maybe reset the button or apply a patch etc.
Thanks again :-D

Getting Frustrating
Alright so I followed your advice on your videos on how to reflash to stock, so of course my bootloader does not show up the same as yours on the video. I can get to the bootloader fine, using the button combo or by using quick boot > bootloader, both have the exact same result, the boot loader screens as follows:
Bootloader Fastboot mode
80.89
and that is it....
Also, my computer using rsdlite does not acknowledge the phone, not omap drivers loading etc. Followed your instructions exactly.
This is frustrating me to no end lol.
I am guessing that because I can get to the bootloader with combo no problem, that the buttons physical connections are working.. At least thats a positive.
Can I flash to stock with openrecovery? Or maybe to an earlier version of Dexters froyo? Other ideas?
Any help would be much appreciated guys, trying to use this phone at work with light sensors to turn off screen is not as easy as they say. OMG....
Thanks so much

The fastboot bootloader isn't the right one. So... if you hold volume up + camera shutter while powering on you end up in fastboot? That's really weird.
Maybe your keys have been remapped somehow? Does anyone know a chord to boot fastboot? Perhaps check to see if your USB port is clean?

Lmao
Just my luck to have a weird problem. I thought it may have been remapped so I have been trying the program buttonremap. It doesn't seem to let me do anything except stop the buttons I re assign doing anything :'(
Does anyone have a proper key mapping file that I can replace with my faulty one to hopefully fix it?
Or any other ideas?
Cheers everyone

Just checked my system / user / keylayout folder. How many files are supposed to be inside, there are a few. I checked the contents of some and they seemed to be the same. Just an idea.... thanks again.

Ok installed anyunlock it allows you to use any physical button to unlock the screen. It doesn't respond when the Power button is pressed, it responded fine to volume rockers, gallery and shutter though.
Anyone know if this would mean for sure its a physical problem before I crack it open and try and fix it.
Thanks guys.

Breakthrough!
I am pretty sure I have fixed the problem, I tapped the phone fairly hard on its sides and back, and lo and behold after a battery pull and replacement it didn't turn itself on, I waited, nothing, so then I held the power button and it started up!!!!
But....I have another problem that happened before that, I am stuck in the boot animation that open recovery uses before going into its program (i.e. where you can load nandroid, wipe dalvik cache etc).
I was about to load a new rom, and was in open recovery, had installed it and about to do the reset and the phone turned itself off, and thats when I got the problem with the sticking boot animation.
So just to be clear, I am stuck in a boot loop, but not with the M logo, the restore logo.
I hope the power button solution can help someone else, as random as it is.
If anyone could help me get out of this boot loop without flashing stock that would be great. ( i can get to the real bootloader now btw)
Thanks again everyone.

Solved it all
Just took the sd card out and rebooted. And the power is getting better after banging it.
Thanks to all.

So, is your conclusion is that the button was stuck and the banging freed it? It doesn't restick?

The Button is not perfect still. Sometimes over sensitive Occasionally it will not even work but it works most of the time. I am just wondering what cleaning solution I could use to free it some more.
It has certainly been a trying problem. Cheers for the help.
Now I need to figure out why I have this strange ghosting on the top of my screen.....

Samsung Galaxy S2 Power Button Not Working
Hi Guys,
Any solution for the power button problem? Current latest Android 2.3.3 Samsung Galaxy S2 also having the same power button problem. Most of the time I can't use my power button to turn on/off the screen (wake/sleep) and there's no menu for long tap as well. Luckily it does wake when i press the only physical Samsung center button.
What i have already tried: Factory Reset, disable Power Saving Mode, Spare Part+ (apps), Screen Off and Lock (apps), and all won't help.
Is there any current updates or patches to allow the power button to work as usual?
Thank you.

take it to the samsung technical centre

Thats if you still have warranty

[Q] VEGAn Observations/Questions

Naturally I bought a g Tablet Saturday and Woot has them today for almost $100 less! Oh well. Big big big improvement from my old FlyTouch2 which was a great idea poorly executed.
Immediately flashed VEGAn with supplements etc. All working VERY well but a few questions/observations.
1) If I wanted to hook this up to a USB or Bluetooth modem (well, actually a BlackBerry) it looks like there is no setup for this? Yes, I know if I could find a way to make the BB broadcast WiFi but its corporate so that's a nonstarter.
2) When I hold down the power button, the menu that comes up it clipped off at the bottom. Is that normal?
3) Screen lock on Kindle software is not getting the accelerometer fix somehow. The trick was to put the thing in portrait UPSIDE DOWN and lock the screen. That caused it to lock it 180 degrees off. But then when it is locked you can go back to right side up (to me, right side up is with the buttons to the top). Of course, if you want to lock it another way you have to experiment.
4) Camera Fun shows camera upside down. No big deal -- again accelerometer I think.
5) Sometimes I am sure the machine is asleep and when I turn it on it is booting from the birds screen. Anyone else seeing this?
6) I don't understand the .nomedia thing although I've read a lot about it. I don't seem to get files erased, but nothing shows up in Video. But if I navigate to the folder (on /mnt/sdcard2) and play videos that's fine. Then later the files will show up in video. Whoops spoke to soon. Now they are gone. What's up with that?
7) My old tablet had GPS but without the external antenna it was worthless. But it still managed to find rough location with WiFi somehow. I assume by figuring out the geographic location of the IP. That doesn't seem to work on this machine. Yes Use Wireless networks is checked in Location and security.
8) What's with the little plastic cover? How hard is it to take out? I don't want a little rubber dingle rolling around inside.
8) In System Preferences, About Device | Status consistently crashes.
9) Does the audio jack support a headset or just headphones? Yeah I know -- I could just try it.
If it matters I'm using Launcher Pro.
Still and all the VEGAn ROM is superb. Compared to the FlyTouch this is super fast, the screen is a joy, and the battery life wonderful. And with the woot deal only about $80 more than a FlyTouch2.

Ok I'll answer some of my own questions:
5) I think this is the unresponsive power button problem. If you press and wait it seems ok. If you press, get impatient and press again you might reboot.
9) No, at least not with a Blackberry headset.

Most of these are answered on the forum somewhere, but I'll give it a shot..

Known issue.

These aren't much help (maybe reassurance?)
1) Pretty sure it's wifi only. Have trawled the internet looking for a usb or bluetooth alternative because wifi hammers the phone battery
2) It happens on mine as well, so it's not just you
5) Same here - I just turn it off when not in use now
7) Only GPS functionality seems to come with the need for an external GPS unit
8) Think this is normal
(Re reading above, it looks like I'm negative re VEGAn - this is not the case. It is way better than what came standard and does everything I need it to do)

Yeah I like it too. Haven't tried the others, but very satisfied with Vegan.

Another observation: Long pressing the Menu button (hardware) brings up the keyboard. However, long pressing the menu button on the status bar does NOT have that behavior.

Clemsyns newest kernel will fix sleep issues. Also has some other great improvements too.
Buttons on status bar do not respond to long presses. Home doesn't bring up its usual long press of recent apps either. Funny, i Never even tried long press on status bar keys before now.

I have Pershoot's kernel. I'll try changing. I presume I shouldn't need to clear too many things in CWM after flashing a kernel. Maybe the Dalvik cache?

[Q] What should the power button do?

Hi all, I'm one of the "new to the gtablet world thaks to Woot" crew. First, thanks for what you all do here, it's a great resource.
I've managed to install the TnT Lite v4.3.0 wthout any problems and everything seems to be running well. My question is, when i hit the power button on the side, it shuts the tablet down and to turn it back on i have to hold the power button down and it has to go through the entire boot process.
Maybe thats what it is suppose to do, but being used to my iphone i imaged it would just turn off the screen and hn bring back up the lock screeen whn it was pushed again. Am i wrong or did i do something wrong when installing? Is it a setting change?
I know this question may be dumb, I'm not as tech-ignorant as this post may make it seem.
Thanks again.

A long press on the Power button should power it up. Once it's gone through the full boot cycle, a short press on the Power button should put it into sleep mode. When in sleep mode, another short press should bring it back to wake mode. A long press on Power while the gTab is fully awake should bring up a dialog box that asks what you want to do, go into Airplane Mode, Shutdown, etc. If you choose shutdown, you'll get another dialog box that asks you to confirm with a yes/no.
I am using the Stock Enhancement so maybe it works differently from yours but mine has functioned this way consistently from the time I got it, even before I loaded the Stock Enhancement.

did you try to press the "power" button lightly. when you press it lightly, it should just turn off the screen. If you press the power button and hold it for a sec, you should see a popup choice (shutdown, sleep, air mode, etc). I agree that the power button is a little sensitive to me as well and I have been using mine for 3 months and it is getting a little bit "wear".
So, it is just my solution, and it may or may not work for you. Since you are running tnt lite (not working on Vegan rom). You can download an app from android market called "Tap Tap App" power button (free)
https://market.android.com/details?id=net.maicas.android.wsleep&feature=search_result
and it will place a icon to your screen or notification bar. It basically turns off your screen, and you can press the volume buttons to turn the screen back on. I have been using this solution for a month now, and have no issues so far.

I'm pushing the button very lightly, and it appears to shut the machine down, or makes it unesponsive. Then I have to hold it down for quite a while to get it to do anything, which makes the machine reboot. When i hold down the botton (when the machine is on) I do get the options, and can put it ito sleep mode that way, and then a light touch will turn it back on. But obviously this is not the way it is suppose to run.
Is there a way to reinstall TnT or shoul i try one of the other ROMS?

Actually I think that is a problem with 4.30. If you install clemsyn's kernel it should fix it. Pershoot's may work too but I only tried clemsyn's.

It sounds like a sleep-wake issue. Like wall_fodder said, you can try to install Clemsyn or pershoot kernel. before you do install the kernel or reflash it, make a backup through clockworkmod and use titanium to backup your apps and data.
I am using 4.2.5 and very stable. Yes, you can reflash it with 4.2.x or vegan 5.1 through clockworkmod.

thanks, is there a step by step on this someplace?

hey all, thanks again, i restarted it in recovery mode and now everything works fine, nothing new installed or changed. Thanks so much...

I heard mixed results about 4.3.0 and sleep. For me, it works (as well as others). But some have reported issues. I'm not sure why that is -- maybe a data wipe is needed?

fyi, the recover reboot only helped the sleep issue for about two presses of the sleep button. However, I installed the Clemsyn kernel through Clockwork Mod and now it works great (after several tests). I had installed tnt 4.3.0 and 4.3.1 directly without CWM. So installed CWM on top of tnt4.3.1 then installed Clemsyn. Probably not the correct way to do it, but everything is working right now.
Lots of hail marys from this newbie while i was doing it though.

Power Button Issue

I have been having odd power button issues since updating to 2.3.4. It is almost like it is getting stuck or something.
Sometimes when I hit the power button to turn off the screen, the screen goes off for half a second then comes back on. This also happens when going from off to on (i.e. flicker on then back off), but it seems rarer.
Sometimes when I hit the home button (and just the home button), it takes a screenshot like I am hitting the button as well even though I am not.
All of this is fixed by just hitting the power button a few times.
Needless to say it is annoying. I thought it might be something mechanical, but I took the case off the back and the issue still occurred. It also seems like the button is clicking then unclicking (i.e. not getting stuck). I had no issues prior to updating to 2.3.4.
Anyone else had this happen or know a fix or workaround?

Yes! I have the same exact problem after the update!!
Glad to see I'm not the only one.
It's very annoying.
My backlight turns on by itself randomly and often if you press the power button to turn the screen off, it goes off then comes back on or flickers on and off. The power button doesnt always turn the screen back on either.
It also gets stuck where I press the home screen and it keeps taking pictures.
HTC better fix this!

I have the exact same problem too since upgrading! I have disabled the screenshot function in build.prop but that only stops the repeated screenshots part of the problem. The main problem with the power button still persists.

I'm having this too, its come and gone to different extents - pretty sure it was happening a bit before the update though.
I'm worried it is mechanical, I couldn't get it to happen with the back cover off but it could have just been coincidence. I can live with having to press the button again every so often but the screenshot thing annoys the hell out of me!

Since the update I've experienced an issue with my power button as well. Sometimes when I hit the button to turn the screen on, nothing happens. At first I thought it was just me but it happens at least a couple of times a day and never happened before the update.
I don't normally turn my screen off by pressing the power button so I can't report on that. Guess I should count my blessing that the screen shot function is not acting up.
Thanks for posting cause was beginning to think it was just me.

FIX!
I found a fix for this, in your build.prop remove the framework line for screen shots and then go in recovery and whipe cache partition twice as well as dalvic twice!
Cheers!

I've just tried this twice but the problem still persists. Sure the screenshot issue is gone but the powering on and off the display is still intermittent.

I was having the same problem with the power button and was thinking it was hardware thanks for the heads up..

am I like the only one without this problem >.< lol. lucky me

I have this same problem too, I believe its connected to the screenshots but i don't know how to turn it off easily (how do I get into build prop?)
This is definitely after the update, I had absolutely no problems with the power button prior to the update.

I don't have any power button isues at all on my European Sensation (2.3.4 still S-On yet). Playing around it just for a week. But the Screenshot thing is a feature not a bug!
Just press <power button> + <Home> to take a screenshot. I like it.

I just starting having this issue yesterday too. Thought it was my power button getting stuck but good to see it's not a hardware problem and hopefully HTC fixes this.

I think you're right. As a test, I used AntTek App Manager to freeze "Scribble" which is also known as com.htc.mysketcher and I haven't had the issue yet. I believe this component is responsible for monitoring for the key combo for taking screenshots. Certainly, after freezing it, the Power+Home combo no longer works for taking screenshots.

I have just tried this but I still have the issue. Sometimes the power button won't wake up the screen and sometimes when I power off the screen it only stays off for a second and then lights up again.

I have this issue too, but I don't think it is software related problem.
It is, as the phone sometimes recognize a power button click as 2 clicks (screen goes off and on).
To see what I mean, go to Recovery and try to navigate through menus - when you're clicking power to enter any menu, sometimes you jump back, as if you were clicking "Go back"...
So, if the issue is even in Recovery mode, so it is not software related. I even restored my stock 2.3.3. soft and the issue is still there. I think it's a mechanical defect

The strange thing is, I even downgraded to 2.3.3 and I still have the problem. I have even flashed stock HBOOT and Recovery but the problem remains. I just don't understand it because it certainly wasn't happening before I upgraded.

Add one more person to the screenshot-club. Haven't had any other problems, but sometimes the phone just keeps taking screenshots when I'm pressing the home key. Extremely annoying, but luckily this is usually solved by tapping the power button. Ofc afterwards you have to clean your gallery of useless pictures... Argh!

[Q] Think my hardware is possessed

So at first I thought the issues I am going to mention were related to the ROM, but after various flashes and really considering if they were related to Apps I have installed, I think it's the device.
Home Button - After my phone has been on for about 1/2 a day or so, I can no longer use the home button as normal. Each click acts like a long press. I also notice when this is happening some screen clicks are like a long press. If I go into the gallery app, I cant open the folders, it tries to 'Select' them as if I were going to mass delete them.
Brightness - I never use Auto Brightness and usually set my screen to Max but ill be damned if my screen doesn't somehow always go to minimum power a few times throughout the day. It can be difficult to change in the bright Phoenix days when power is set to minimum.
Any ideas? I don't use any cases that might be depressing buttons or anything like that. I do have a screen protector, but Ive used this vendor for years.
Thanks

What ROM are you using? I've got the same problem with the home button acting as a long press. This behavior started when I moved to a 4.2 based ROM - first CM 10.1 and now AOKP JB MR1 B5. It's really obnoxious. Not sure if it's the hardware or software since it goes away when I reboot. I'm also not using any case or screen protector.
I might try downgrading to a 4.1 ROM to see if it really is something in 4.2 or the hardware. Been hesitant to do so thanks to 4.2 moving everything on the SD card to the /data/media/0/ directory. (Can't post a link, Google 'android 4.2 0 folder')
Curious to hear if anyone else is having this issue?
Update: Should have searched Google before searching XDA! It is a known issue that was fixed 4 days after CM 10.1 M2. Google for 'CYAN-283' to find the ticket. Can't wait for M3 to come out so this can be resolved!
