My S3 is on stock ROM.
I've been having an issue of endless reboots, so I googled the issue and came upon removing the power button thinking my problem was due to a faulty power button. I did so in removing the power button, but the issue is still present. It doesn't have an endless reboot anymore, but just doesn't stay on once it's unplugged from a charging source (won't even stay on when charging through my computer, only an outlet).
I honestly can't figure out what the real issue could be since removing the power button did not solve it. Battery? Faulty part on the logic board? I am pretty baffled and any help would be appreciated.

I tried to turn the screen off, but it keeps turning back on. I've had this issue for a while and looked it up. Most people said it was a hardware issue, but the thing is...now it will not turn off the screen at all. I know the power button works because I can long press it to get the power menu as well as hold to restart, but not turn off the screen. Also, I can activate the "lock" feature in TWRP as well with the power button. I had this issue on an older rom, so I wiped EVERYTHING and installed revolt, yet I still had this issue and as I was typing this, I got the new issue of it never turning off. I don't know what's causing it. Any ideas? It's been happening for a few days now.
Attempt 2: Now I have the stupid turning off issue. Now, every time I press the power button the opposite happens. It turns on for a second and then turns back off. I'm thinking that this is a hardware issue. Anyone else disagree?
Attempt 3: Back to same issue, turns off and turns right back on in like 2 seconds. Going to call Samsung and see what this is about.
[EDIT]: I should mention, I have the same vibrate issue described in this thread. I'm suspecting a stuck power button. Great. Time to talk AT&T into giving me an early upgrade.
A stuck power button won't allow your phone to boot up completely. So you're probably ok there if you can boot up and type in an app.
You do have an issue though. Something got borked up somewhere. I would try going back to stock completely.
Backup important files, wipe EVERYthing on the phone at least twice. Then using Samsung kies on a PC do an emergency firmware update. Once your update completes perform another factory reset and see how she's working. If you still have a problem then contact Samsung. If no problem, enjoy your phone!
Eh, I tried the wiping everything (internal, not the sd card), but I guess I shall try moving it to stock as well. Do you suggest keeping TWRP or should I install stock kernel, recovery, and do a firmware update? I might also dump my phone in rice to see if maybe some water got in there (doubt it though). Also, I might be screwed if it's otherwise. Been over a year since I bought the note.
Also, are you sure it's not stuck (partially or sometimes maybe)? My phone is constantly rebooting on and off for no reason and sometimes this happens, other times the power button is okay. But when it does reboot, it vibrates a lot. Sometimes it'll just keep vibrating and never reboot like it's turning off and on constantly and I have to press and hold the power button a few times before it starts booting again.
EDIT: I also realize it could be a combination of issues and one of these issues might be a battery one. I do have another battery and I can feel a noticeable bulge so I'll go home, change the roms, battery, and do a firmware update and see how it goes.
Would just like to add that flashing an official firmware through kies did not fix my problem. Furthermore, now I'm getting the invalid sim problem and it keeps asking me to restart. I had this problem before and just recently (a week ago) got a new sim and now it's back. Maybe it's an hardware issue?
Hi guys
Having some issues with my S3, bought in November 2012 and worked perfectly fine until a few months ago when it started turning off and rebooting, it would get to the initial 'Samsung Galaxy SIII' logo and loop on that until the battery is pulled. It'd work fine for a few moments after it booted to the lockscreen and then do it again.
I got it working again after I left the battery out for several hours, afterwards its been working fine apart from the occasional turning off, looping on the inital boot logo. Fixes itself first try so I've been happy to live with it if it only does it occasionally.
So about 20 minutes ago it turned off and looped. No worries, pulled battery out for a few minutes, put it back in and turned it off. Usually it would work absolutely fine after this, but instead it kept looping. Got a bit concerned, so pulled battery out for a few minutes, put it back in and it worked. Then it did it again, so battery pulled out for a few minutes, put back in and it works fine. I've had it charging since it started working and it seems to be going fine now (could be just a weird superstition of mine, charging it seems to keep it alive?).
I can usually tell when I'm using it if its about to reboot, if I go to lock the screen using the power button, it acts as if I long pressed the button (power options appears). So I use the back key to get out of it and try locking it again. Does the same thing and then it reboots within a few seconds. Could be power button getting stuck?
Adding music/data to the device does seem to flare this issue up for a little bit, but those could be completely unrelated
Factory reset fixes it for a little but that isn't possible all the time of course.
Any suggestions on how to fix or prevent this issue? Is it the sudden death syndrome flaring up? I'm on 4.1.2 XXEMG4, the latest for the region of the phone, so the sudden death fix is incorporated.
Thanks heaps
EDIT: Found the solution to the problem today. Seems that the issue is the power button sticking. I verified on my mothers s3 that holding the power button down does reboot the phone, by skipping the whole shutdown sequence and going straight to the bootup. It seems that because the power button is sticking, the boot sequence isn't able to complete so it will reboot endlessly.
Try pulling the battery out, and firmly (but not so firm it will break) and repeatedly press the power button around 10-15 times. The video I saw suggested smacking the side of the phone against a hard surface but that may be a little extreme. Anytime the power menu comes up when you go to lock the screen, quickly press the power button heaps of times until it locks and you will avoid a reboot
Sounds similar to the lead up I had to SDS. The Sudden Death fix can also cause freezes and reboots. Or teh NAND memory could be dying but from something other than SDS

These issues only began appearing a while after the updates including the SDS fix came out (which I know doesn't completely rule out SDS). Absolutely 0 issues when I was on 4.0.x, aside from Android itself crashing on a couple of occasions.
I still have until the end of october to lodge a warranty claim if need be, so I'll see how it goes
I created this new thread because the others dont really describe the actual problem Im facing with my phone,
Suddenly my phone restarted and its not starting up moreover once or twice it did make it to the home screen but it keeps on locking like the power button is being continuously pressed and again its restarting.. Moreover when i remove the battery and place it again it starts restarting again..
Is it a software problem or should I take it to the service center?
Service centre if factory reset did not fix .
I encountered a similar issue a few weeks ago, my phone kept rebooting now and then. Knowing about the "sudden death" issue, I verified and it all was OK. My problem was a hardware one. The power button had an issue, so almost whenever I tucked it into my pocket it rebooted. Continuously. Even after I removed the battery and put it back it kept rebooting. I took it to a GSM service and I had it fixed in 10 minutes for about $10. They replaced the power button (the plastic and that rubber-like thingy). I'm glad they didn't have to remove the mechanical button. Also you could check the battery contacts (on the battery itself) and clean them - use something hard that can wipe off any residue.
Repaired
Thanks for the replies, the power button indeed was at fault, replaced and now its working great
Gentleman, my optimus g is showing some really strange behavior. If the battery is fully charged, or above 60%, it works flawless, after it drops below that, there is a chance that the power button will start locking in the pressed down position. After this happens, it is a no come back, the phone keeps bootlooping until the battery goes dry. At first I thought this was a problem with the battery, I got It replaced and the problem persists. I am starting to think this is a problem with the power button flex cable, and I was wandering if anyone knows how to replace it. I've replaced cell phone's screens and such, I have taken the motherboard out and found the flex cable, but I am not sure how to remove it, as it seems that it is firmly glued to the chassis. If anyone could give me some suggestions I would appreciate it, thanks
Hi, ive just switched back to stock rom but before and after this my power button has become hyper sensitive and has caused constant bootloop. I tap the power button lightly and then the phone shuts down and goes into a bootloop. I dont know what to do. I need to fix this ASAP because this phone is my daily driver !!!
Is it rellay a bootloop (so you see the bootlogo) or do you only see the splash screen (Samsung galaxy sIII logo)?
Have you replaced your battery with a non-original one? I had the same problem with one from Anker. After using again my older samsung battery the problem has gone.
But it is also known that the S3's power button has a limited lifetime, so it could probably be broken, so a repair would be needed.
