Sensitive power button

My samsung galaxy s2 has sensitive power button for some reason. I'm not sure if its the roms i have been flashing. But im on IML74K_Ics_Perfection_UCLD2 and if the slightest touch on the power button turn on my phone when it is off. Or it can turn it when the phone is locked. But i can even press it all the way down for even a split second without it rebooting and going into a bootloop and taking me many tries to actually boot up. Is this a hardware problem with my phone should i restore my phone to stock and return back to tmobile or is this a ics problem with the roms?

Have you tried using any different roms? Is the issue still present? I haven't had or read about this issue before, and I've tried my fair share of roms.

I have tried the darkside roms but im starting to think its the phone and i think is should get it replaced then.

Yeah it shouldn't be so sensative.

i just started experiencing this last night. RIGHT after getting my battery replaced after two weeks of dealing with that problem and finally realizing it was my battery and not my phone. then i tried to take a screenshot of my new battery stats (without all of the huge sudden depletions) and my phone reset as if i held the power button down for 5 seconds. i read about a woman in india getting her button repaired for 550 rupees ($10), but i'm wondering if i should just get a whole new unit and be done with it. the problem with that is dealing with setting up all my apps over again. i have titanium backup (root version) but the last time i got a new phone it didn't put all my apps back on my phone. maybe i did something wrong. i'll email them for detailed instructions and see if it's better to get the button or the phone replaced.

Definitely the power button! After I hardbricked and revived it, my phone had an internal short, which made my phone constantly power off my phone, restart my phone over and over, etc. Josh at mobiletechvideos had to try and work around. He disabled my power button and remapped the wake buttons. So now I wake this phone via the volume rockers on roms that support that
I digress. If you can't send it to T-Mobile to get repaired, give mobile tech videos a shot. Just 35$ and they're super swift

I wonder what's actually causing this power button thing??
I was literally just browsing email, clicking around a little fast, back to home screen and FLASH!!! my camera flashes and all this same $hit starts happening...boot loop, sensitive button, booting out of recovery mode even. I just doesn't add up to sudden button failure...does it??? Why would the camera just flash out of nowhere? Some of the boot loops would also get interrupted and start over. Recovery mode is also kind of screwy. I tried to restore to a backup of Beastmade rom and it just reflashed Sith, the same rom I've been on!! And all my other backups/nandroids are missing. Something is fishy here.
I did recently go to TWRP and have been on the Sith Rom (clones & drones).

Yep its the power button ! I had this problem a month ago , but for me it completely went away .. maybe something was just stuck in between and the constant pressing of the button loosened whatever it was

The thing that has me curious is how mine started acting up. I wasn't even touching the power button. I was just clicking around gmail, went to home screen, the camera flashed and it started boot looping. It would sort of zap out in the middle of a reboot like there was a power issue and lot of other stuff was messed up including TWRP recovery! This tells me there is something else going on...more ROM related. Seems like all this started happening when these ICS ROMS dropped...none of them are as stable as Juggernaut, Paradox, etc...NONE of them. My power button does indeed seem defective, but it almost seems like it was a bi product of something else.

ROM related. No. Its a faulty power button. Been many threads describing your situation. Ends up being a faulty power button. Mobiletech offers a power button service. Its reasonably priced.

Sent mine for repair of power button. Waiting for it to come back. I bricked it after I contacted them trying to restore to factory and they replaced the PBA (motherboard) as well.

I was lucky enough to get flashed back to stock and have a warranty replacement on the way. Still has me wondering if something else wasn't up. Just seems like all the ICS based ROMs have been very buggy compared to the very stable Gingerbread builds. I sure enjoyed my rooted phone but this has been a PITA losing my device...it's my work and life! I haven't been stock in so long it will be interesting to click around a bit and see if I'm not better off stock. I'm due for an upgrade next month so I may well be on to an S3 or whatever else is out.

Just got my replacement this afternoon!!! Man...what a couple of days it's been without it! Holy crap, I had no idea.
Anyway the new phone shipped with 4.04. So that's cool. So far THIS is the most stable ICS rom I've used. :silly:

I know this post is ancient, but ....
Two years later, I'm experiencing this power button problem and I'm on KitKat - SlimKat 7.0 stable.

Dah... just went locally to have it serviced... got screwed at 100$...
Should have searched online before...

I had the SAME EXACT issue. I had to literally remove my power button because my device would reboot every few minutes. I use the volume keys to wake the device and sleep shortcut in the notification bar to sleep. If my device turns off, I have to turn it on with a USB, which is a major hassle but I've grown used to it.

Phone stuck ON - Second one.

About three weeks ago my launch Epic 4G Touch got its power button stuck on. In the weeks prior I had had occasional glitches where pressing the power button would turn on the flashlight (an AOKP feature where if you hold the power button from off, it turns on the light), or when pressing it to put it in sleep I'd get the power-off menu. And occasionally it would get worse, where pressing the power button would lead to the entire phone shutting off and restarting after a few seconds, as though I had held the power button down the whole time. Anyway, as I said, it finally reached the point where the button was apparently stuck sending the On signal the entire time. And it was clearly hardware-level, as if I'd pull the battery and put it back in it would INSTANTLY power itself back on.
I took it to the Sprint store, they reviewed it, couldn't fix it, and ordered me a replacement which arrived a few days later. I've had that replacement for about two weeks now without any hardware problems. I did switch to AOKP again, but I've had no issues whatsoever.
Until today, when it progressed through all the above-mentioned symptoms and all the way to stuck ON permanently, in the span of a few hours.
Has anyone else experienced this? Is there any logical reason to suspect this could be a fault of the sofware I've installed? I've never heard this symptom before, which makes me think it's extremely unlikely or others would have caused it, plus the power-on from battery implies to me this can't possibly be a software issue. But I want to be sure before I get it replaced yet AGAIN and cause it again, or have the store try to blame my custom ROM (they never said a word last time).
Help?
EDIT: Pretty confident I just confirmed it's a hardware problem. I booted into CWM to try to make a backup so I could flash to stock and confirm it wasn't software. The power button of course didn't work in CWM either. What I hadn't thought of is that I couldn't get back OUT of CWM without the power button. Even a battery pull would put me right back into it. I finally get desperate and yanked the battery and banged the phone on the desk against its power button a few times, then put the battery back in and the phone didn't power itself back on. I then hit the power button, booted to CWM, and managed to use the power button to reboot to system. So that confirms it's hardware to me. So I guess the question shifts to: two phones in a row with this problem, and I've never seen it mentioned before. Am I just incredibly unlucky, or have others experienced this? Second: anyone successfully manage to use a scenario like this to talk them into a different phone? I'm not loving this chain of events, and I'm not loving to hack my phone to get a good stock experience. I'd really love to switch to a Galaxy Nexus. Any tips?

I have the same problem just got it today....Really need to fix this

Seen a couple different threads about power button. Someone took it in to be repaired/replaced only to have it go bad again later. I guess I have gotten lucky, there was a good while that my power button liked to stick and not function properly. It went away one time after I accidentally left my phone in a hot car. I suppose my issue could have been from something sticky being spilled on the phone though.

[Q] Any way to disable the power button?

Hey guys,
So I've got an S3 running AOKP at the moment and I was wondering if there was any way to disable the power button. It's been malfunctioning, and causing my phone to reboot constantly. Sometimes even when off it continues to think I'm holding down the power button and cancels the boot process...
Any ideas of a workaround? I'm out of warranty and can't want to pay for repairs at the moment.

Hi,
I am having the exact same issue. Very strange as it decided to do this while checking my email (finger no where near the power button) and I have never had any issues prior to this.
I'm running CWM, CM10.2 and I CANNOT BOOT into recovery (CWM) or ODIN, best I got was the CM loader screen then it reboots.
Even if I disconnect the battery, wait 30 minutes (fully charged) and replace the battery, it attempts to boot itself again. and again and again...
The best videos I've seen involve smacking the phone on the power button side (not going to do that, at least hard) I think it may be a random power button failure. I will be disassembling the phone tonight and trying to open or close the power button contacts and wipe my phone before it goes back....
Yoiks!

It's very random for me too. Sometimes it'll work all day then it'll take like an hour and a half to turn back on.
Quick question, as I've heard this from a couple people. Do you use an otter box?
Regardless I'm 90% sure this is hardware related and has nothign to do with software, because all the cases I've heard of this have had different roms, one of which was stock unrooted.
Pretty frustrating. Not sure I'll buy a Samsung again to be honest.

This started gradually happening to me too and I bought both my phone and Otterbox in July 2012 when it came out. I noticed with my family members' S3's that their Otterboxes were different in regards to the power button (it stuck out more) whereas mine hardly stuck out at all. I got a warranty replacement this past July (2013) and the exact issues you described began happening. It started out as random reboots and as of yesterday, I can't get my phone to boot because it thinks I'm holding the power button down (therefore not letting the boot process finish). I took my phone apart, expecting the power button to be an easy swap like it was in the GS2, but no, it's a part of the friggin motherboard. I also am looking for a way to disable the power button. I'd recommend that if you are able to get it to boot even once, that you make sure to backup all your stuff. Fortunately all my pics are backed up since I can't boot my phone anymore, but other files are currently inaccessible. I wonder if anyone knows if some sort of electrical tape or something could prevent the power button signal from transferring so that we would be able to boot our phones?

I had the same power button issue with my Captivate as well... and thought that issue had been looked into. After 14 months of use on my S3, I noticed this issue appeared.
Solution (well not quite): change key layout to disable power button. Re-map volume down as "power, wake". Yes, by doing this, I am losing volume down button. Also, when the phone is off, I still need to press the power button to power it up. My fix of changing the key layout file won't take charge until after the phone boots up.

[Q] [D2LTE] CM11 Sudden Death issue

Hey All,
I'm currently on the CM11 04/22 nightly, and have made it all the way up to the 04/27 nightly to try and resolve this issue and have not been able to. Basically - the sudden death issue has been hitting me very hard - I can't use my phone at all.
I understand the 04/11 nightly is stable and doesn't have this issue, howevery CyanogenMod does not have this on their website.
Does anyone have this install available? (CM-11-Nightly-20140411-D2LTE.zip)
Thanks so much in advance

please explain what you mean by sudden death? thanks

I'll be using the phone (say checking my Instagram or reading a book on Play Books) and the screen may be on for about 5-6 minutes. The phone will suddenly shut off on its own. I'll start it up and then shut down again when the phone is loading. It will also sometimes say it has 1-2% battery when it really has 45% (which is what it shows when I plug the phone in).
Hope this clears it up.

I had the same issue a week back. Was the most frustrating thing ever...
I finally narrowed it down to the power button. It actually had to do with the power button switch which is soldered to the motherboard. The power button was super sensative, therefore being engagded at all times, causing the phone to hard shutdown every time I tried to turn the phone on.
How I fixed it:
1. Opened my phone up
2. Broke the switch off
3. Done
Now I use my phone without a functioning power button but it was a quick and free fix so it doesnt bother me.
If I decide to do so in the future, I can also solder a new switch back and get the power button working again.
DO NOTE: This might now be the issue you may be facing, so do your research
Finally, I watched this YT video which showed me how to break the power button switch and eventually fix my phone: https://www.youtube.com/watch?v=3Glllc7bEJs
Good Luck

I'm fairly confident that this isn't the power switch. And if it were I'm not sure how comfortable I would feel breaking the power switch off.
The thing that begs me to think this is a software issue is that I'll have 45% battery, the phone will die, and then I'll try to turn the phone on again only for it to tell me I have 1% battery left. I'll put the phone on charge (after it dies again) and it will say charging - 45%.
Anyway I've rolled back a few updates and it seems to be fairly usable now...

Try cleaning the USB port real well and don't use a cheap cable. Use a needle and make sure there is no lint packed in there. These things can cause the phone to cycle itself even when not plugged in. I've fixed several doing exactly what you describe.

[Q] Help!!! Only on For seconds?

So today my phone started to power it's self off. When I power on it shows the kernel screen for a few secs then powers off. I can boot into Recovery (CWM) and when I select reboot it does the same. If if I boot in to Download Mode, it only stays on a few secs.
Is it the power button? Any ideas?
I'm running the BMS Kernel and C-Rom 6.6. I have had this same rom and kernel for weeks with no issues.

Interesting, I have not had any issue with the battery. I'll look into it. Any way to test without using another battery?
Anything else it could be?

Using CWM built in key test it seems it is the power button, when I touch the power key it reads as if it is being touched multiple times or heklod down. Any Fix without replacing the button?

Not that I know of I have only seen replacing it fixes it

Ive seen several people report that opening it up and jiggling the button can help, but when it does it is only temporary.

It's fairly easy to replace. You can buy a button off ebay for fairly cheap and look on YouTube to replace it.

I agree it sounds like a stuck power button. My experience with this problem first showed in a captivate of my moms. It was very bizarre tho. On stock ROM it would constantly do the vibrate, cycle, vibrate etc. On a custom ROM however, it has had zero problems with the power button. Maybe try that? Not a sure fire fix, just telling what happened with the Cappy. ☺

If this is power button problem you can try (what i did and worked, but it is your choice and you can damage your phone) drop little of oil in power button and press couple time with out battery in phone.

That's actually fairly dangerous for your device. I would suggest an air duster if you think it's dirty.

I'm actually having the same problem. It just started his morning.
The phone won't boot normally. I get the kernel boot screen, sometimes a Samsung screen, and then it turns off. 2-3 seconds max.
I can get it into download mode, but after 3-4 seconds, it spontaneously shuts off.
Recovery mode (CWM) is completely stable. I can get in, make back ups, perform a key test, etc. When I run a key test, it shows that the power button is a little sensitive, but not crazy. If I jiggle it some (mostly back a little) it registers a key press, even if I'm not fully pressing it. If I do press it fully, sometimes it doesn't register.
If this is really a button issue, why is recovery stable? Even if I put the phone on a flat surface with nothing that could touch the button, the phone still doesn't stay in download mode (it just shuts off.) When I put the phone in recovery, place it on a flat surface, and perform the key test, the phone isn't registering a key touch.
I've tried 3 different batteries, kept the phone plugged in, popped the battery and held the power button to discharge everything, wiped the cache, wiped dalvik cache, and used CWM touch to reboot (and avoid the power button all together.)
The only think I can think of that's maybe different is that gapps was FC'ing more than normal this morning (before the phone crapped out.)
I'm running StockMOD ROM 4.4.2 R2 with the Ktoonsez Kernel for TouchWiz 4.4.2.
EDIT: Also, when it's plugged in, the LED doesn't light up. I'm not sure that it's actually charging. I do have a wall charger, so I can verify that the batteries I'm using are charged.

Try flashing a different rom from recovery to see if it still happens. Also try a factory reset. If you get as close to stock as possible and it still happens it raises the probability thst its hardware.
If you put the battery in and wait a few moments does it turn on by itself?

Band-aid
@DocHoliday77 I messed with the phone a little later tonight and recovery became unstable. I'm convinced it's a power button problem now. I think the internal mechanism gets stuck and that's the issue.
When I put the battery in, the phone does try to boot by itself.
I used the advice in this post: http://forum.xda-developers.com/showthread.php?p=53915864 and I was able to get up and running again. I opened the phone up, blew some compressed air on the button, tapped the flat side of the button lightly a few times with the end of my screwdriver, and put everything back together. I was able to get back into recovery, and then reboot normally.
I ordered a new power button and I plan on replacing it next week when it gets here, just to be on the safe side.
You guys at xda are life savers!

The booting up on its own after inserting the battery is a classic symptom of the power button going bad. Glad to hear you got it working for now, and that you are ordering a replacement. Everyone ive heard about getting it to work using any number of methods have always found it to only be a temporary solution.
Just a thought, in case it starts up again, maybe remove the plastic piece until you replace the switch. Hopefully that would help prevent it from getting accidentally pressed in your pocket or by bumping it into something. (You could probably still access it with a toothpick or something like that if needed)

I agree it's the power button. I just posted about my little experience on Google+
I tried seriously whacking it on the floor and everything. I wouldn't recommend that but I had no warranty and no funds for repair. Others had said that beating the crap out of it worked so I thought why not lol...
https://plus.google.com/116004961340303353216/posts/ig2ogLeUWJ8
Long story short, my beating it up didn't work but it did wake it up. It falling on the floor however, jarred whatever was stuck and it now works like a charm...good luck
