[Q] S3 keeps restarting on its own - Galaxy S III Q&A, Help & Troubleshooting

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

Had to get my phone replaced!

Had to get my one day old Nokia 800 replaced today.
Got everything setup last night and decided to power it off just to give it a restart. The phone would refuse to power back on. No amount of button pushing/reconnecting to the power would make it start up again. No power, nothing..dead.
I managed to get it to restart after performing the three button reset. No problem I thought maybe just a one off. Turned the phone off and put it on charge overnight and this morning the same problem returned.. Could not power on. This time the reset would not work at all, no matter how many times I tried.
Carphone warehouse swapped it over in store today for another handset. Hopefully I'll have more luck with the replacement.
Edit: already seen someone else mention a similar problem on here. Hope there's not a bigger issue.
How do you perform the three button reset? My phone randomly decided to turn off whilst I was driving and now it wont turn back on
Yes I've been in that spot as well. For five minutes the phone wouldn't respond to any power button press. Long, short, whatever. I was already starting to slide into panic mode when it suddenly came back alive on another short press.
It's not the only hardware problem I've encountered, I also have problems with touchscreen and buttons and a loose part inside the device.

It's my phone dead ?

Hi ,
My phone suddenly died on me. I was using Flipboard and after I close it by pressing the power button once short.
After few seconds I wanted to check something else and I push the home button as usual and the lock screen shows up I did my unlock pattern it shows me the green color and then it gets stuck completely froze. I didn’t have any choice than to press and hold the power button. After holding for more then a minute the screen went off but it didn’t vibrate as usual when is all shut down. I took the battery out , put it back and no luck. I tried all the button combination for recovery, download … nothing.
The battery was about 50% when it happened.
I’m on SLIM ICS 4.2 with FLUXI 0.3 kernel and I never had problems up to today.
I tried to charge it and nothing happens , no charging animation..
It’s anything else that I can try or to send it to Samsung service, but that will take more likely few weeks.
I’m lucky somehow as the warranty will expire on August 2.
Thx
You could try a new battery. You could also try a jig. If they don't work, send it in for warranty service & hope they don't notice or care you've been messing with it/been running non stock firmware.
If they do notice/care, you won't get warranty service. If they don't notice/don't care, you will. Getting this fixed under warranty is no certainty as running non stock firmware voids same.

Sounds like a hardware malfunction. Get it serviced mate.
Also even if the charging icon doesnt shows up, leave it plugged like an hour or so and try buttons again
Thanks guys ,
I tried other battery also ,nothing , not even the first Samsung Logo and/or the first vibration when it's on
I kept it plug for few hours or so and still nothing. I don't have a jig unfortunately .
Definetly ,I'll send it to be repaired , luckly is the company phone and I may push it for an SIII if cannot be repaired.
thx.

[Q] Random reboot and bootloop 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

[Q] Samsung Galaxy S3 shuts off randomly. Won't turn on consistently?

My Samsung Galaxy SIII smart phone has only recently been having issues. My phone will turn on, will be charged and function as normal - ie, no performance issues at all when the phone is actually on. But sometimes, my phone will randomly shut off with no prompt or message. Sometimes it will attempt to turn back on itself, other times I need to press or even hold the power button to turn it on.
The real problem is when it boots, it SOMETIMES (3/5 times average) will begin to boot, then the screen goes black again - ie, the Samsung logo will show up upon vibrating, then shut off or reboot and try again (this can sometimes happen singularly or in tandem). Other times, it will boot as normal, sometimes working normally, other times just randomly doing the abrupt shut down, and the cycle starts over.
I've tried taking the battery out, rebooting it, booting to safe mode, removing battery + keeping it out for ~10 minutes to discharge, etc. My phone isn't up to date, as my phone is rooted. However, I haven't modified my phone or done anything to it in a long time, and this has only has begun happening recently. My current firmware is rooted stock Android 4.2. Are there any other solutions besides formatting my phone? I cannot send it in/get it replaced by my provider as my warranty has expired. Thank you. :angel:
Go to the Play Store and download emmc brickbug check.
Get that diagnosed.
If it's good i suggest you do a full wipe and update it to the latest samsung 4.3 update.
Ultimate GS3 sudden death thread.
Well you better get up to date, best to start with a factory reset and the latest stock rom first.
I guess you're running an unstable leaked 4.2.2 firmware,so I would suggest you to install stable 4.3 firmware.
Maybe your power button got stuck..
To find out, push your power button and keep hold it even the "samsung galaxy s III GT-I9300" appear.
Do you experience the same thing or not.

I found a fix for my S3 which was doing EXACTLY what many of you are describing. I will get to the fix and it will sound ridiculous, but it worked for me and for the other people responding to the posted fix. ***** Hint: my problem was the power button and the fix was free and easy though may require you to be pissed at your phone as I was at the time.
Before getting to what fixed my phone. It seems like every one with a Samsung phone Sh*tting out in this manner should go through the well-conceived sequence I post below in the link. That guy though through the problem and made a great help list even though I found myself with a phone that was a mess even after all of those steps. My phone just vibrated when I tried to start it or maybe it began to show a graphic screen of the boot process before it went to black again and just vibrated. I am stuck with 4 more months of verizon contract so I was desperate and unahppy to say the least. I tried at least 50 time to boot my phone yesterday and went to a verizon store they were no help as expected especially when they saw a boot screen image that they did not recognize... I was one of those rooting creeps that they are not obligated to help...
first link:
http://thedroidguy.com/2014/03/fix-galaxy-s3-wont-turn-troubleshooting-guide/
A stuck or malfunctioning power button can cause... getting random reboots, lack of starting, lack of posting, getting stuck at various screens in the boot process and then going to a black screen which may just accompany a vibrating phone or a seemingly dead phone. Our problem is the power button being "stuck" underneath/inside of the janky, crappy little clip on power button that you are actually pushing in on your phone.
see this youtube video. In other words the thing you push is only pushing something else inside. I took my power button out (it clips in) cleaned out the cavity by blowing and with a toothpick and I was fixed!
http://www.youtube.com/watch?v=pQ-U-Q_NdOo
I was pissed at my phone so where the guy in the above youtube video says something like tapping his nail (finger nail) into the power button or whatever I was pretty aggressive and crammed my thumbnail down the sides of the power button until the janky little piece of crap actually popped out revealing itself as a clip kind of a thing. I then blew the hell out of the hole with all of the breath I could muster and took a toothpick and depressed the actual power button several times and "cleaned out" and cleared out any hair or gunk (really did not see any) that might have been in the socket. I put my power button back in (just clips in by itself if you put it in the socket the right way and push down) and I have had NO PROBLEMS since. Start with the first link I posted but be wary of the clearing Cache part unless you no what you are doing ahead of time. I had just done a factory reset and total wipe with TWRP before installing a new ROM so I did not have anything to lose. You might... I don't know enough about what resides in "cache" to advise you. Then if you are still in trouble listen to the second post which is a video. I actually crammed my thumbnail down into the power button cavity on both the top and bottom (the long axis) of the button aggressively enough that the visible button popped out. Then I did my blowing and cleaning, etc... crammed the visible button back int - which clips into place and I have been stoked since. Hope it works for you if not, sorry!
*As a side note, I sort of assumed that the problem with my phone (and I bet yours) has something to do with power: either getting to the right place in the phone from the battery or the power chord OR the f*ing power button on our cheap, janky plastic yet expensive Samsung phones might be a problem because before the weird random reboots and not booting began the power off dialog (like when you hold the power button down long enough and you get the "reboot" "power down" "airplane mode" menu kept coming up while I was surfing watching youtube or even talking. I figured it was time to install another ROM, did so twice and still had the same issues. I reflashed recoveries back and forth from TWRP to the other one several times too. Nothing worked until I cleaned out the power button. Go figure.

I tried a similar approach and it looks like it actually worked. I just took the plastic cover of and removed he 10 little screws and played around with the plastic thingy that depresses the power button. I don't know what exactly fixed it but is seems to work.
So you might not have to remove your power button but instead just play around with it first and see if you can't get it to function properly again.
Thank you so much brjoon1021!
Galaxy SIII I9300 shuts of randomly but only when not used
I have a problem with my S3 since about a week now. First it was a standard S3 with stock ROM and not rooted. The phone would turn itself of 3 - 5 times during daytime and also at night when charging.
What I tried:
- Clearing battery connections
- Cleaning power button
But finally I think it's not a hardware problem. Loose contacts, battery connections or a power button problem would probably cause more shut downs when I was using it. But in my case it's the opposite: it always shuts down when I am *not* using it.
So I rooted the phone and flashed a custom ROM on it: [ROM] [4.4.4] [CyanogenMod] [GCC 4.8] [Excellent] [31/12/14] ArchiDroid V3.0.2
That was succesfull, but after that I still had the same problem.
When do I have this problem: as stated: always when I am *not* using the phone. It's lying on my desk or next to my bed, charging and no program is running.
When I don't have the problem: when some program is running on the foreground, at night during charging if I keep the clock on the foreground (daydreaming), when I have waze running (in my car) etc.
I have the impression the device only shuts itself down when in deep sleep mode.
I also tested if it was a case of Deep Sleep of Death, but when the phone is shut down, I can not text to it, the LED does not light up.
I can boot the phone by pressing the power button once for about 8 seconds, so that seems a normal boot and not a reboot.
Any suggestions on what I could test? Or how I can find out what the problem is?
Thanks!

Well it started to get worse every day, so we tried factory reset once more and after that, the phone just died. (only colored rubbish is shown on the screen) ...
Never ever buying Samsung again. Piece of crap ...
Anyway we had chance to buy LG G2 on the sale. I know it's quite old, but the price was perfect and it's many times better than S3. :good:

HTC One M7: Power button doesn't work, but only when screen is on?

So about 3 weeks ago, I dropped my HTC so now I have a large crack running down the middle of the screen. However I haven't had any other problems up until last night. The ringtone volume turns itself up without me even touching the phone every now and then and once it does that, the power button stops working. But it does work again once the screen is switched off, meaning I can turn in on but not off. The power button functions fine until the volume button acts up the first time after restart.
I factory reset my phone thinking it may have had something to do with the software but the problem came back within the hour when all the updates started rolling in. Once it did, i booted it into safemode and the problem seemed to stop but I don't know what's causing it. Could it be an actual bug in an update or is the damage to the screen simply too much for the phone itself? Has anyone ever dealt with a problem like this? Any help will be appreciated as I know it's expensive to fix these things and I don't want to go to the shop to get it fixed only for the problem to come back as it's software related.
