Late last night while playing games on my phone it froze and I had to hold in the power button to reset it.
When it powered back on, it froze almost immediately, powered down after a couple of minutes, turned back on and repeated the cycle. As I was already in bed I plugged the phone in and assumed it would fix itself and be fine in the morning.
Except it isn't. This morning the phone is very warm and is still poering on, freezing and powering off. If I do a battery pull and turn it on myself, it does the same thing so right now I've just got it turned off.
I noticed when it turned on that Google Wallet icon would appear in the status bar and it was at this point that the phone froze. I was able to go into Rom Toolbox before the Wallet icon appeared and managed to disable Google Wallet at startup, but this had no effect. I went into recovery and cleared cache and dalvik, this had no effect.
What may be causing this power cycling? I haven't installed any new apps in days, I haven't downloaded anything, and I turn my phone off and on every morning and it's never done this before.
If it helps I'm on Freeza's deodexed stock unrooted MD4.

I think it's fine. It can certainly be pressed with no problem and it seems to release itself as normal. I am going to try restoring a backup from last week and seeing if it still does it after that.
I would recommend maybe doing a FULL Wipe, and Flash. Might be a Bad Flash.
Sounds like the sudden death syndrome which is the power button failure. The physical button looks and feels fine its the internal contact which meses up. Try tapping on it or blowing some compressed air into the power button area. My understanding is they repair this as its a known problem.

Last night I had dropped my phone from about a foot on a sitting-swing and it hit the ground. I have the black case from the sprint store on it. After that I attempted to turn it on and it just got stuck on Samsung loading screen with the genocide 2.0 logo below it, it then proceeded to be stuck there and eventually rebooted, this never seemed to end. When I attempted to plug it in to charge it the battery charging icon appeared but just has the loading symbol inside of it frozen, after many battery pulls and attempted clockwork-recovery boots failing I decided to go to bed. When I awake I went and tried to turn on my phone which immediately booted up into clockwork recover, fearing for my phones safety I backed everything up on it and then rebooted it. It seemed to work fine! It came on flawlessly and worked well. Throughout the day the battery seemed to drain extremely fast and then eventually died, having just gotten home I have found that the same thing is happening and it won't even charge.
Re flash the ROM then flash journaling on zip right after you flash the ROM then re boot & download you're apps fresh cuz you're data might be corrupted! Hit the thanks button if I've helped in any way! ;-)

I flashed back to stock rom to see if it would turn on, same thing happens, and I don't know if this is significant or not but when my phone boots up the buttons light up, then turn off, then back on again and stay on until the phone reboots itself or the battery is pulled.
EDIT: I have a strong feeling it's my physical battery that is causing the issues because it was working completely fine earlier yesterday.
Try booting in safe mode by holding power and the physical menu button until the phone gets to the lockscreen... Im curious to see if it helps because safe mode might help us get out of soft bricks? I wanna test this theory...
No it does not work, just get stuck at the Samsung loading screen. I don't honestly believe this is a software brick either because of the way it's acting, as I said in my above post I believe it's the physical battery and will probably be going to get it replaced soon
Hello, last night as I was sleeping, I noticed my phone randomly rebooted. Thinking it was because of a kernel issue, I ignored it. I woke up, left my house, and another reboot. Half an hour later, constant reboots; boots up, goes to the lock screen, reboots, etc. I came home today, my pc does not recognize any phone connected. When I plug into the wall, I get a red notification light for a few seconds, then the light dies. During the constant reboots, I could go into download mode, but after a few seconds, it reboots. I never was able to get past the Samsung boot logo after recovery mode. I unplugged battery and replugged, nothing.
I was on rooted Jellybam 4.2.2, Ktoonsez kernel. I cannot remember the last time I flashed anything, but it was atleast a few months.
My microsd also died a few days ago.
Life sucks; any comments?
EDIT:
on second note, I just replugged battery and quickly went to download mode, and it lit up, then died after a second or two.
For some reason, when I put in my battery, the phone turns on.. I thought it only does that if the phone was uncharged for a few moments..
Could my internal sdcard be fried?
You don't have a brick if your phone still turns on.
Check to make sure the battery is good
And also check and make sure the power button isn't stuck.....
Those have been the culprits for many "bricks" for a while now.

I switched the battery with a back up, same problem.
How do i make sure the power button isnt stuck..? It clicks when I press it.
EDIT:
I just took the phone apart and freed the power button so the display and the motherboard are laying side to side with only the display connected to the motherboard.
The phone still turns on automatically when i plug in the battery.

I think it might be the power button thats some how stuck, but I cant figure out why.
I opened the phone and everything seems fine..
I spam pressed the power button out of boredom and my galaxy booted up fine, then died again.
EDIT: wow, i kept spamming the power button and now it boots up fine..
please delete this thread
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.

Sounds like your battery is dying. Might wanna look into getting a new one.

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
Two days ago, my T-Mobile Samsung Galaxy S3 dropped out of my coat pocket as i was running for the bus. I picked it up and saw the screen was cracked along the top left and bottom left hand side. Everything was working for the past two days and i figured i'll just wait till Christmas to get a new phone. This morning i took my phone off the charger and turned it on. The Samsung logo flashed, and then the boot animation for Slimrom (the custom rom i'm currently running on) flashed for about a second but then the screen went black. I did a battery pull but the weird thing is whenever i put my battery back in, even without touching the power button, it boots up by itself but then the screen goes black again. I can access TWRP and download mode but they both go black after a few seconds as well. I was able to successfully turn on my phone and have it fully function for about 15 minutes after putting it back on the charger, but it quickly blacked out again. It also keeps randomly booting up by itself which is weird. Im guessing this is a problem with the screen itself, but could it be a software issue because the device keeps booting up by itself? If it is the screen, will i have to buy a new one or is it not worth it? I've also tried using a different battery and i have the same issue so it can't be that. Any help is appreciated!
Sounds like an issue with the power button, it probably got stuck somehow either when you dropped it, or after you dropped it. Do a simple search for power button and you will find ways to fix it!
Holy crap i didn't even think of that! It makes total sense since every time i even tap my power button, even for just a second, it turns on. I've read around that clearing the cache or a factory reset could work. Is this true?
Unlikely, unless it's a software issue but it's always a possibility. Slam the phone against something to try to get the power button back into place, or open it up and try to see if you can fix it yourself, or replace it
The problem seems to be gone. I haven't had any issues for two days now. All i did was press the power button really hard multiple times. Thanks for you help man!
The thing is becoming increasingly unresponsive when something tries to wake it from deep sleep. A few weeks back someone tried to call me, and the screen turned on and flashed the dialer app, but the touchscreen was unresponsive. I'd click "Answer" and it wouldn't register. Clicking it repeatedly, clicking anywhere on the screen, trying to turn the screen off and on, nothing would work. The phone basically froze, only not exactly, because the sound was still playing. Like a minute later, I held the power button down and got the shutdown pop-up which seemed to rouse it out of whatever infinite loop it was stuck in.
This morning, it happened again when my alarm went off. I could not get the damn thing to stop. It happened again an hour later. When I tried to hold down the power button, the phone reset.
When it came back on, a bunch of my settings had been reset. It reverted to the default keyboard and started showing me tutorials like it thought this was my first time powering on the phone. Additionally, the System Updates menu shows I'm on the latest version, but all history of past updates has been wiped out.
I'm getting really concerned that this thing is gonna die on me any day now.

How about factory resetting the phone, starting from scratch re the software installed? Yes, you'll need to reinstall your apps and reconfigure it, but it's like starting fresh. If it still malfunctions, then you can look deeper.

Thanks for the advice, but I ended up grabbing a Galaxy S8+ off a friend for very cheap. So, not really an issue anymore.
