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.

[solved]A very odd issue. phone vibrates 3 times.

well literally happened at random only thing ive done is run titanium backup. but when the phone is fully powered off and i go to boot into the bootloader by holding power and volume up. the phone vibrates 3 times and does nothing. it however powers on and boots to the ROM fine no problems at all.
i can only wonder what this means but i assume its nothing good. noticed this a while ago dug around for a while and found nothing. so i posted my question.

In some ROMs the fastboot is disabled by default.
Try flashing another ROM and see what happens.

[Q] URGENT HELP:Phone won't boot

I've had they Hercules for just over a year now but have only been using it for the past four months. I have only downloaded educational apps. However, yesterday i was not using it and came back to find it vibrating every 2-3 seconds. I removed the battery and left it out for an hour. When i replaced the battery, the phone began to reload but stopped during the boot,made a noise I've never heard before and began to vibrate as if going into recovery/download mode. I have been running ics for the past 4 months. The phone does not boot at all and is very frustrating . I have also tried charging it with no luck. Can anyone assist me with this problem??

sounds like you have the dreadful power button fail it gets a little jammed up try sticking a toothpick or something skinny in there and wiggle it a bit see if that works for you if not check if your still under warranty are you rooted or stock ICS?

u have a bad power button. try unsticking it.

Agreed. A friend had a similar issue and his power button was stuck.

I'm rooted and the warranty is up

Strange enough this just happened to me 10 minutes ago. I did manage to get the phone to boot after slapping the hell out if my power button which gave me the only means to get into recovery so now I can comment from experience. Ive been running pac for 3 weeks. Just yesterday my phone started doing really weird ****, dont know if it's just coincidence, calls would go through to random people, every time I clicked gallery I got a random reboot, I couldnt call voicemail, and trying to change wallpapers gave a reboot. Today I was changing a wallpaper and boom random reboot then began the loop and vibrating. A few things I noticed while this was happening, if I attempted to go into recovery the samsung splash screen appeared followed by the stock kernel splash( samsung and the blue bar at the bottom) which made me believe it wasnt the power button but indeed rom or kernel problem, also my led flashed once while going through the vibrate loop and I know the power button has nothing to do with that. I did manage to get pac to boot about 4 times by slapping the hell out of my power button but it went back to the loop after a few seconds so the next time I managed to get it to boot I held the power button and booted to recovery. Once I was able to get in to recovery I restored a liquid smooth back up. Ive powered the phone off and on with no problem. Now I'm just waiting to see what happens through out the day. I was running pac with cerux when this happened. I truly believe this is not a hardware problem at all until I get it again with another set up. If you need help I getting your phone to boot I could possibly be of assistance so pm me unless you want to keep getting responses from people who haven't experienced this at all. This was the single most scariest experience Ive had since I ve been flashing, even worse than my brick because I knew I bricked immediately.

Stuck in Bootloop. Please help!

I'm on Liquid Smooth v2.1, Android 4.2.2. No custom kernel, just whatever it comes with. Been running fine for months.
This morning I dropped my phone in my car (a few inches drop) and it went into a bootloop. It eventually booted into Android and I backed up all my apps and texts to my SD card. But afterwards it went into another bootloop and now its stuck there. It will start booting, and then restart (most of the time before the boot animation even comes up). I need to get into recovery so I can restore an older Nandroid or maybe try wiping the cache. I have tried using power/volumeup/home, but it bootloops by the time recovery is starting up. ADB on my computer will not pick up the phone. Sometimes for a few seconds it will show up, but it has an "offline" next to it and by the time I enter "adb reboot recovery" it says no device found.
If I take out the battery for 30 seconds, it makes it pretty far into the boot.
What steps should I take next? I know ODIN is last resort, but I'd prefer not to go there. Thanks guys.

I have a similar problem I think the power button may be the issue, when it's boring up tap on the power button with your bail as you would on a table. Also try to put your sideways with power button down that may help.

Wow. That sounds like a possibility. Dropped from my lap to my cupholder, could've landed on the button. I'll try it in a bit.

I was able to get it to boot for a few seconds, and the power menu kept on coming up until it died. Does the phone turn off if you hold down the power button for a long time? Seems like I gotta get that fixed. I'll try the sideways suggestion in a bit.

Yeah, if you hold power and never let go, it'll reboot over and over. It's intentionally like that so if you ever have the system lock up you can still do a kind of hard reset. (Better than a battery pull, though that can still be necessary if you want it to just turn off)

That's what I thought. Anyone know the difficulty of repairing this myself? Or a cost estimate? Holding the button at an angle seems to make it work for a bit. Sideways didn't help.

I've heard there's some YouTube vids that may help. I've seen a few people say they were able to do it themselves.

this seems like a similar job for the s2, I would imagine that the s3 is very much like this video.

Anyone know if I were to remove the power button completely, would the phone work without it? I don't really need it, and removing it would make the phone usable. Just wanna make sure the phone doesn't run a check or something. I'll order a new power button in the spare time and install it later.

it'll prolly work but if phone shuts off not sure if you will be able to turn it back on without a power button, what I did for the time being is get the phone of and basically tap on the side of the phone with the power button towards the floor kind of like trying to get gravity to push the power swith inside to be back to the normal position. Then don't touch the power button, there are apps in the play store that can function as your power button.

Yeah, I watched a YouTube video and he fixed it like that. So I basically hammered the button as hard as I could with my nail for a minute straight and now it doesn't bother me anymore until you press it. I can live without the power button, but I'm probably going to have to remove/replace it since I can't risk bumping into the button on accident. Thanks for the help though!

Does anyone know of a method to turn the phone on without the power button? I know on my Nexus One you could Insert the battery while it was charging to force a reboot.

Afaik you'll just have to restart every time till it's fixed.

Yes, but how would I go about restarting it without the button?

There's apps in the play store. Button savior might be one. Can't recall names for sure.

Screen sometimes won't turn on

I have installed CM 10.1. Occasionally the screen will not turn on when I press the power button. I have to hold down the button for 10-20 seconds to reset the device to get it to power on. Happens at least 3-4 times a day. Anyone else have this issue or ideas on how to fix it? Thanks.

No one else has seen this issue?

Many ROMs have their little quirks here and there, this could be one. I use hashcode's ROMs so this is just speculation though.

I had this issue with twa_priv's rom. If I keep at the button, pushing it multiple times at different intervals, it would eventually come on. Interestingly, if I went into the developer options and put the CPU at the full 1200MHz, it didn't happen.
Not having this issue with CM (though I'm running 10.2) so not sure there.

This was a common occurrence in cm10.1 with TWA_priv's build I believe. This is called a Sleep of Death or SoD. I thought that was cleared up, but maybe not. If there is a newer version of the ROM that you are on, I recommend trying that. There is no way to recover from an SoD except to force power off like you did, and start back up.
