G2 gone crazy? On/off-button not working.. hmm..

My G2 works as it should, but recently it started to behave rather weirdly...
The only button I cannot use, is the ON/OFF/STANDBY-button. It doesn't work at all. And when I am using the phone, i.e typing a text message, it randomly gives me the "shut down, airplane mode, silent mode"-menu, just as it'd happen when I press the On/off/standby-button. It works on its own... when I am typing this, I see that the "shut down, airplane mode, silent mode"-menu keeps on coming up and then disappearing after 4-5 secs, even if I am not touching the phone at all!
However, this sometimes goes away so I can use the on/off/standy-button again like normal, but then maybe after few days, it "locks" again and start "behaving" on its own...
What is happening with my G2?! What have I done? Can it be an application that I've installed, or? Any ideas?

I would reflash your rom after a complete wipe (factory, dalvik) start fresh. I seen this in another thread with someone else. If it doesn't help it could be a hardware problem. How long have u had your phone?

Seems to me like a hardware issue. You might have to remap your on/off button to something else. Try this link http://forum.xda-developers.com/showthread.php?t=850464

I see...
I am new to this flashing thing... Hmm.... I am supposed to meet a friend who want to buy the phone, but I suppose it's not possible to get this fixed until then?
What happens if I reset anything to factory defaults? Would the power-button work as it should then, or?
Also, I've got pics and movies on my SD-card. How do I completely "refresh" the phone so there's no trace of my photos/videos?
I've had my phone for roughly 2 months. Bought it as new then. Worked nicely until recently.. Haven't dropped it on the floor either.

Nobody who knows an answer to my issues..?

Apparently not...

Hey did you solve this issue? My Power button suddenly stopped working as well.

Backup your sd card data, pics and such to your pc,,,, dropbbox is the best btw. Then use cwm to format the sd card. as far as the power button, its prob a hardware flaw. sell it cheap and move on.

Could it be a problem with the flex table connecting the two halves of the phone?
I have a similar problem with my old touch pro which is done to the cable.

C'mon guys -- its probably just a stuck button. You have too much grime in there.
You MIGHT be able to clean it out and get it working without taking it apart by doing the following...
You will need a small spray bottle with some rubbing alcohol (NOT the 99% kind)
1. backup the phone, just in case, shut it down and REMOVE THE BATTERY.
2. spray the button area. Saturate it, try to get alcohol into the cracks around the button. If you get some on the screen, wipe it off.
3. work the button for a couple of minutes. push it push it push it push it push it push it push it push it push it push it push it push it push it .
4. Let the phone dry out -- the alcohol should evaporate pretty quickly, but I would wait two or three hours before...
5. replace the battery, turn on the phone and test.
AS USUAL, DO THIS AT YOUR OWN RISK.

Well I did a replacement and all is good now just finally rooted it

Curious issue with my power button

Hi, I have a curious problem with my power button.
It seems to work ONLY to turn the phone on, once my X10 has booted my power button will do nothing, even held down for a second.
I've tried many ROMs including stock SE and EWJet and am currently on CM7, same problem.
Also, it's managed to function normally again for a very short time (30 seconds or so) after exiting navigation (to a non-dev this seems like evil magic) which I tried repeating but was successful only once or twice.
Using a softkey to power off my screen atm and waking via home button.
I DID throw it recently in a fit of rage and I lost my camera button but this problem doesn't seem to be physical.
Can someone tell me wtf is up with that button?

Hmmmmm... If it gets triggered at power on, it means that it's not a hw problem. Try repairing 2.3.3

To me, it does seem to be physical since it happens with all the ROMs you've tried.
Maybe something loosened when you threw it?

Unscrew the phone and screw it up back again. Believe me im not trolling, might just work for you

Nexus S power button conspiracy theory/oddity

My power button has been malfunctioning for about 2 months now. That isn't to say it is 100% dead, but at times it'll work if I smack the button about a few times, and sometimes it will be completely unresponsive. I have read up on the subject and found a thread with a response from a guy claiming to be an engineer who said the micro switches they use in these phones are somewhat weak and only work for a limited number of presses. Recently, I changed roms, and to my surprise the power button worked great for a short period of time. Since then, I've found that when my power button starts acting up, wiping the dalvik cache put it back to normal. This lead me to thinking, and I've come to believe it could very well be a hardware problem that is meant to happen. I am by no means a coder/programmer but I have studied it enough to know that certain code can be written for a device that sets a "timer" for a piece of hardware to die out or malfunction. If that's the case with this, then it makes sense somewhat that wiping the dalvik cache resets this timer for a short time. Anyone have any thoughts? Am I crazy tinfoil hat wearer or does this make some sense?

I AGREE! I thought it broke a while ago but I did a complete wipe and put a brand new rom on it. Heck I almost sent it to Sammy but for some reason it stared working. I dont think its the dalvik cache though. I have a feeling its ClockworkMod Recovery because sometimes it says a key was disabled and I had problems after that. I couldnt lock my phone.

well, you solved your own theory in your statement. since when does smacking your phone equate to a software issue? my power button went in august, mostly. it started showing the behavior that you described about 4-6 weeks beforehand. i say mostly, because the physical button doesnt work anymore(rarely a response from it). but ive figured out how to work it to my advantage/needs. i can wake my phone by shaking it now, and put the screen to sleep. also can be done with a light smack in the right place on the back of the phone. but to be practicle, i remapped my search button to use as a power button and wake my phone with the volume button. really, the only hard part is navigating in the bootloader menu since the volume buttons wont work there with the power button broken. so ive learned to work it by lightly, very lightly, tapping on a certain place on the back of the phone near the power button. this "loosens" the volume buttons and lets me navigate the menu. then i tap the phone again to make a selection. this in no way indicates a software issue/conspiracy to me. when it just started displaying this behavior, i thought it might be a software issue too. but it turned out to be all physical damage.

You know, the funny thing about when it stops working is that it's never all at once.
It's a degrading process of malfunction until it takes repeated button pressing, not so much force, to work. After that it works so seldom that I'm forced to do something about it. It's for those reasons I think it's something more than a hardware problem.
From your experiences, even after a full wipe/new rom installation, your power button still doesn't work, if only for a brief time?
P.S. The new touch based recovery from team win works really well for those of us who can't use our power buttons

Hmm my guess is that there are multiple issues that result in a malfunctioning power button. Props to remapping your search button to lock your phone. It would be a great work around if my phone ever had this problem again. Have search to lock the phone and volume keys to wake it. I'm unsure how you remapped your search button though. Maybe you can tell me how?

Agreed! If you have no access to a computer with adb/fastboot control the touch ClockWorkMod recovery would be very useful.

ive been using twrp recovery for a while. even the non touch version has a no power button option. but i dont believe that theres anything else but hardware issues here. it is a degradation. at first it comes and goes, later it mostly just comes( ) and doesnt go. i can even hear a slight rattle in the power button area now if i shake the phone.
about after flashing.. at first, 50% of the time it would work after flashing, but it was just coincidence. but now no. btw, i flash many times a day, even then when it first started acting funny. flashing, wiping, it just doesnt make a difference, its coincidence.

you want v0241. i have all the power button functionality with my search key except waking the device(volume rocker wakes my device). short press screen off, long press power menu, long press plus volume down for screenshots.

@tw1tchy, I totally agree it is multiple factors, which is why I can only speak for myself based on my experiences, although your overall experience seems to be similar to mine.
@simms22, I have never noticed a rattle in my phone, its likely that you and I have different causes attributed to the power button failure.
Not trying to beat a dead horse but just for the sake of being thorough, have you tried ODIN? I noticed a substantial difference when I ODIN'ed back to stock.

I really like my Nexus S, but I kinda hope this power button self destruct kicks in soon. I see it as a feature - to make buying a Galaxy Nexus easier to justify. Good looking out Sammy.

I've had a similar problem for the last 4 months or so. It started when I dropped my nexus without the cover onto concrete floor. Not good I know.
But anyway...ever since then the power button been funny. Sometimes it didn't work at all and I couldn't turn the screen off and on. It was really bad. It took a while but now I kind of know how to handle it. Still annoying mind u.
Basically with mine the trick is to press the button really really hard towards the top end and it works fine. I've also noticed what some others are saying about changing rooms and doing resets etc. It seems to help as well.
But yeah...I still love my nexus. Lol. I think by me dropping it is the reason for my problems. It probably landed badly and loosened some part of the connection in that section or something. But as I said...all Is good now that I know the trick to it.

I've had my NS since Christmas Eve 2009 and the power button completely stopped working 2 days ago. I did notice over the past few weeks that it wasn't responding properly. TBH, my NS has been through a LOT in the past 14-months (multiple impacts, spillages, kids etc), I'm surprised it's lasted this long
I'm now using the ButtonRemapper app to use 'search' as the power button. Works great! Plus my volume keys wake the phone up so all is ok.
I love my NS and wish I bought another one when CPW had them for £150 sim free!
It might be time for me to let go of the NS , just have to decide which phone is next (but thats for another thread lol)

ugh mine is under a year old. im very angry that this happened so quickly. im gonna try giving samsung a call. hopefully the will replace it. i shouldn't have to hack my phone in order to make it usable.

@rener78 You seem to have a vast misunderstanding of how sarcasm works. Just as future reference, posting dry, tasteless irony up on the internet as a smart-mouthed statement of ill will is about as practical as a chocolate teapot.
@staplebox Lol! Well played, sir or madam. I can't say posting a thread containing the words conspiracy theory doesn't grant me at least a well placed snarky comment. Although to be fair, I was kinda bored when I wrote it.
@ALL Yes, I get it, we've all dropped our phones before. I guess I expected a bit more from Sammy since my little old HTC hero that I beat halfway to hell is still going strong, while I pampered this nexus and its already giving me problems >1 year in but that's a whole different discussion I suppose.

great mine just went out yesterday... had mine for a ltl over a year now.
No tapping certain areas or anything works.
I did notice it slowly degrade over the past few weeks.
I used the fix my power button app so my volume keys wake up my phone, but sometimes after using that 5 or 6 times it will stop working too so i have to plug my phone in the charger to turn it on. Is there another way of getting the volume keys to act as a wake button??
edit: i'm gonna try out that button remapper i saw in an earlier post.

if you are using an ics rom go to the main settings, security, lockscreen.. now disable the lockscreen. you can now wake your device with the volume button. its a feature built into ics.

interesting did not know this. Thanks, I think I'm still gonna use the button remapper to change the function of the search key to the power so I can reboot and stuff and go into recovery and such easier since i'm running cm9.

thats what i do. my search button has all the features of the power button but being able to wake the device.

Here's another question what if i need to pull the battery?? I'm rooted and running CM9 what if i go into a boot loop and i need to pull the battery with no charger around (i know how to do it with a charger) would the button remap solve this?

no. the button remapper app doesnt do anything when off or the screens off. honestly, i no boot many times a week(because i test the trinity kernel as its being developed before release), ive figured out a system of light taps near the power button to let the volume buttons let me scroll, and to select in the bootloader.so for me its a non issue. to power up from being powered up, i dont do anything. a, pluging in powers it. b, tapping the back powers it when no usb is available. c, it powers up by itself usually, seconds to a few minutes after powering off.

Being a heavy user of my nexus s since July 2011, the power button died last Sunday.
One of the most important problems i had after that was that i was unable to lock bootloader before giving the mobile to samsung service, because the stuck power button caused problems to fastboot commands and the bootloater usage(menu) in general.
Finally i decided to go to the service and give the phone. The result was that in about an hour they replaced the button and gave me back the mobile. The repair was covered by the 2 years warranty and the unlocked bootloader did not cause any problem to that.
Up to now i have a "brand new" nexus s and i hope that the new button will last much longer.

Power Button

No more reboots since the new update. But the power button doesn't work anymore. I have to use the docking station to turn the TF101 on and a app to turn it off.
Sent from my Transformer TF101 using xda premium

Is it going in and out?
Did you drop it recently?
My bezel was bent out of shape from being dropped onto the bottom left corner and yesterday I took it off to bend it back in shape. When I put it back on, power button wasn't set properly, so just popped it back off and back on again and it works just fine.
It's fairly easy to do. Just remove the two T5 torx screws by the charging port, then pull out and up on the bezel (some used a guitar pick or some plastic piece to pry it out) all the way around the device and it comes right off. Then to put it back on, just put it over the device and simply push it back in and it'll click back in place.

The button works fine and I never dropped it.
If my TF is on and I get a dark screen I can use the button to turn it on.
But I can't turn it off with the button.
If my TF is sleeping for a few hours, the button can't turn it on, I have to use the dock.
The funny thing I can reproduce this behavior over and over. First I was thinking its the button, but for me it seems to be a software issue.

If you root it you could use terminal emulator, su [enter] reboot [enter]... try rooting with viper mod, at least you could turn it on and off with terminal emulator... not sure what the command for shut down is, power off maybe? Sure someone knows it...

power down command
Under *nix 'shutdown -P' (or '-p' under *BSD except OSX) should power down the system.

And why don't you just friggin root already? You know it takes less than a minute right?

I don't agree with Horndroid much, nor do I share his animus about your not rooting, but I must say that having your device rooted is SOOOO easy, and totally reversible, and would make all of this 100% easier for both the community to help you troubleshoot, and for you to do what we need you to do to help us troubleshoot..for example having emulator terminal access or ADB control of your device. For the latter you don't NEED root, but it makes things SOOO MUCH EASIER. So yeah, just root already...

I'm experiencing the same thing. After the latest update, my power button doesn't work correctly.

Power button does not work TF101
I have the same issue since latest android update. Have all latest firmware etc and it is a brand new TF101.

Perhaps Asus will include a power off/sleep soft key in the settings/bottom bar section for future releases...

ICS (I think) has Widgets for regular reboot and to turn off if your button doesn't work or you don't like using the button. [Sorry, I just realized that the icons came from an app called Quick Boot (reboot) that does require root to work]
So after you root and install that app - Just go to apps, (where all the icons are- top right of home screen) then Widgets tabs at top, swipe around and you'll see several buttons with lightening bolts labelled for the various options including both power off and reboot. (At least in Revolution HD ICS ROM.) I never even tried vanilla stock ICS. I have been on Revolution since Honeycomb. When ICS came out I waited a few days for the Revolution version to come out.

Custom roms and non-removable battery

So this phone has a non removable battery....
A few times now I have seen the need to do a battery pull when you're installing recovery or something goes wrong with a rom install....esp when you get into a bootloop....how will this play out on a phone where you can't?

As it's been stated countless times, either a combination of button presses, or holding down the power button for a long period will cut off the power. The exact method varies by phone though

Check the HTC One X forum. Fixed battery, and no problem whatsoever with taking care of freeze ups or lock ups. Just hold the power Key & Volume - keys for like 10 seconds, and it reboots.

i smell a bad future for me and this phone then. my volume keys are compeltly worn out on my phone right now, i can barly get to safeboot(power+volDown) as it is much less if any soft reset to break a freeze needs the buttons x.x
luckly this will be my second phone and ive found a way to nearly use every button from the screen already, still feels bad.

Besides after root you can install apps to reboot right into recovery mode or fast boot if you are a flashoholic like me to preserve volume keys

I saw a video about the phone that stated that holding down the power button for 10 seconds will turn the phone off. It's something they have to build into something that doesn't have a removable battery, not just for users but for them as well.

Same thing as a desktop, or laptop, or tablet, or any other phone that locks up. Hold the power button. It's a hardware-level thing, it works regardless of what state the device is in.

This. My HTC One X can do this anywhere - even fastboot and recovery. It's hardcoded to the button logic.

It's the new Nexus, man! Hopefully you won't be putting as many ROMs on this as you would with other mobile devices.
I started doing it on my Galaxy Nexus a while ago and then I ended up going back to stock because it was just so good and I found I never needed a custom ROM on it. My HTC Desire on the other hand... well, let's just say that that thing has had a real beating with me flashing new ROMs on it almost every day! Haha!

On my Xperia T you must keep down the power button and volume up for five seconds, which forces the phone to shut down. Maybe it's the same?
