Power Button Won't Turn Off Screen

Issue: Power button won't turn screen off. Either it doesn't respond to the button push at all or it treats it as a long press and will pop up the phone options menu. Power button wakes phone just fine. Also, if I boot into recovery while experiencing this, not all power button pushes register within recovery (ouch).
It's weird because I experienced this for the first time like 2 months ago a few hours after flashing a Tiamat kernel (actual kernel may have had nothing to do with it), but after fiddling around with my phone it started working again.
Well, it started happening again on Saturday using CM 7.0.3.1 w/ GoDm0dE v5. I got it to work again by doing a factory reset, then restoring a backup. Well, it came back last night and persisted after another factory reset. It was very consistent today -- for hours it would either do nothing after pressing power or it would pop up phone options. Finally, a did a factory reset within CM7 and also within Amon-RA 2.3 and then restored a backup from yesterday and the power button functioned properly for about 1.5 hours.
Has anyone experienced anything similar?
ROM: CM 7.0.3.1
Kernel: Stock
Recovery: Amon_Ra 2.3
HW: 003

Never had that experience. Could be a number of things. It might be the Kernel/ROM mix, the Kernel itself, the ROM itself...But I would think that if it was any of these things, I would have heard about it by now from other users.
It could be something as simple as a short in your power button or the connections underneath it. Might just short out at the right times to make you think it is something you are flashing. Try shooting some compressed air in there (might help).

Thanks -- I actually tried the compressed air. I'm thinking it's hardware. It seems to have gotten worse in the past hour.

im having the same issue. i googled it earlier and it seems like theres alot of people have that same problem. its looking like a hardware issue. I can tell you one thing tho its pissing me off.

I unrooted and it actually started to do the same, but when waking the device. Brought it into Sprint and getting a replacement on Wednesday.

Had this exact same issue up until a few days ago. I took a needle and went around the power button front and back, something unjammed I guess and now it works like a charm. I've also had this with a software problem. My power button wouldn't work, even in recovery. I restored a nandroid and this fixed it. Hope this helps! Best of luck.

I had the same issue. Sprint said it wasn't the button but the board not responding to the button. Got a new phone.

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.

Phone rebooting like crazy...help

I literally have never had a problem like this with this phone, but just recently I flashed the new AOKP jb 8-29 build and after a day or two of using it I started getting random reboots where the phone would crash and then start vibrating in intervals. I couldn't get it to stop unless I pulled the battery. Thinking this was just a bug with the rom, I just rebooted to recovery and wiped and flashed the latest jedi mind trick v7. I let the phone sit for a little bit after first boot, but when I then tried to go through the setup I got the exact same problem. Now the phone crashes like this every time I boot up and even while I'm in recovery mode! Someone please help if you know what might be causing this.
EDIT: Now it's doing this every time I put the battery back in; I can't turn on the phone or go into recovery while it's vibrating like this

Sound like a faulty power button. I've seen many, many threads like yours. Almost certain that's the case. Mobiletech offers a power button service. Check them out

I think you're right because before every time I put in the battery the phone would turn on, but I tapped the power button a few times to loosen it up and put the battery in and it didn't turn on. Is there any way to remote start without having to touch the power button that you know of? Thanks for the advice btw

This same scenario happened to me just yesterday morning. I researched it and this issue does seem to be popping up more frequently among Samsung phones. Maybe power button design is faulty and they're starting to wear out now after a year plus of use? I sent mine off to MobileTechVideos today to be fixed. I feel so lost without my phone!

What I've read is no. Its not the button its self, but the circuits behind the button that mess up. Unless you are really skilled at soldering and can re wire the board, I don't see that happening.

S3 Wont Wake Up

My S3 is running stock 4.4.2 and isn't rooted (though it has been in the past). At times my phone will not wake up after the screen turns off.
I have to pull the battery to get it to work again. This doesn't happen all the time, but it can happen 5 or 6 times a day. This has been
happening for about 4 months. I did a factory reset and the same thing happens. There is no rhyme or reason to when this happens.
I have read a bunch of posts about this, but there seems to be no definitive answer. Some say do a factory reset, which I did. Some say
it is the version of Android they have, but this goes back a couple of years and everyone is on different versions of Android.
As a habit, I always press the power button to turn off the screen so I do not make any pocket calls. To use the phone, I press the power
button again, or the home button to wake it up.
The phone is 2 1/2 years old and except for this glitch, it has worked flawlessly.
Any ideas?
Thanks,
Ian

Just a guess, but probably a faulty power switch. It happens fairly often, but usually displays different symptoms than yours. It would be the first thing I'd focus on though since it's very unlikely it's software/firmware related.

My thoughts too are that it is an hardware issue rather than firmware. Had a similar problem once and it turned out to be the power button. However, with a device of this vintage, you can never be too sure.
Good luck!
