More info?
when does it auto reboot?
Does it get hot?
did you try "Factory data reset"?

Did you possibly flash new firmware and that happened? You need to give us some more details.

Well it sometimes just randomly reboots...

I don't got problems with listening to music, maybe some app is messing your phone. if you can't find the problem do a "Factory data reset", if this doesn't help you can bring the phone back and get a new one. It can always be a faulty phone.

My Arc sometimes reboots on me too but not randomly. It's always when it's doing something that maxes the CPU and I switch between apps simultaneously. It's quite annoying, no doubt. My old Desire never did this.
Hoping for a future fw update!

I'm on my third week with my arc and it never randomly rebooted.

It's being reported in the SE forum as well. You don't notice the reboot unless u put your phone within your view the whole day. Thats when you will notice the random reboots.

try ddfw, I ensure you will get one.
I even encountered one when the screen was off and it's doing nothing

I'm pretty confident its caused by buggy software and not broken hardware.
Looking forward to flashing some custom roms and kernels to get around this and up the perfomance

my arc have randomly rebooted at least 15 times in the past 3 days. it's so annoying. what's that thing with stuffing tissue paper on the back does it work?

i've reflashed mines twice now, and done reset to factory default on top of that after the second flash for good measure, and it's still rebooting when it feels like it. i uninstalled a weather widget, and i got almost 5 hours of constant uptime. i'm about to reflash it again and not install anything, maybe just battery monitor so i can tell how many hours/minutes i can get before it reboots again.
i read about the battery fit, and i have tried various things to try and see if that was the issue, but nothing physical seems to make it reboot, and like some others, i have seen it reboot when the lcd is off and the phone isn't doing anything.
i'd really like to be able to use this arc!

mine just had the first random reboot...first I thought that the battery was all drained out but then realised after switching it back on that it was at 20%...
the phone was on idle, locked...weird!!!

Just had my first random reboot after a months use, was using google nav while charging from the cigarette lighter. Quite annoying as i was trying to find my way somewhere and suddenly realised i hadnt had any instructions for a while. The phone had gotten quite hot - i think google nav must work it pretty hard.

If you use the home button to switch between recent apps a lot (i do) then it's pretty obvious if your phone's been rebooted as the recently used apps list is empty, so i'm fairly sure this is the first time my phone's rebooted on its own.

Random reboot here, too. ^^
I was typing an email with Google Mail app (with wifi and mobile data connection turned off, actually), when the screen became all coarse and broken (does anyone remember old DOS games crashes? ^^) and then it rebootet. Everything fine afterwards except for my email, which was gone.

How do I diagnose random reboots for my Note 2?

For the past 4 days my Note 2 has randomly rebooted at least once a day. I wasn't using the device for most of the reboots and just noticed that it rebooted because of battery drops. I don't really know what could be the cause since I don't remember changing anything recently. Is there any way I can diagnose this without root?

How about just flash stock rom? If you dont have lots of apps which you've used, then it should take care of problem without needing titanium backup which needs root. Just save ur data using kies and flash stock rom from sammy.

I'm actually currently on stock and unrooted. I was just wondering if there were ways to find out what caused the reboot such as logs and such? Or if there was an app I could install to keep track of what causes a forced reboot?

You could download alogcat from the marketplace, its free and will save a log of what's going on with your phone.
It might help find out why its happening

for me it happens cause the power button is so easy to press while phone is in pocket.
keep it pressed for some seconds by accident and phone reboots. even if screen is locked.

If your rooted run a logcat and that will tell you what happened right before the reboot, reboots are usually a Kernel Panic meaning something caused a big enough problem that it couldn't be recovered and crashed the core of Androids software "The Kernel".
As others have noted flashing a stock rom ideally via ODIN and then testing your phone may let you know if you had bad software or a hardware issue. Custom roms can have bugs that will cause kernel panic a stock rom should be 100% fine and reboot free

I find mine will sometimes reboot after copying something to the clipboard.

I had reboots on my previous unrooted HTC EVO. The problem was an app. I was able to diagnose the problem by looking at my install/update log. Basically, I uninstalled all apps back to the date I knew it was stable and waited to verify it was stable. Then added back one app only and waited. Repeat. About a week later, I added an app that caused a reboot within hours. I uninstalled it and the phone remained stable.
Here's where I found a chronological listing. If you have multiple devices, it will show all apps for all devices (tablets, vizio, phones,etc)
Google Play> My Android Apps> at the bottom My Orders & Settings.
This gives you a cronilogical listing of app installs and updates.
Mine turned out to be a call recorder app that I had put on the phone 4 weeks previous.

Seems like a Samsung issue:

Bad SD cards are also a notorious source for spontaneous reboots. If you have one inserted, it should be easy enough to retract it for a while to test it. ..
Note'd too from my N7100...

I'm also experiencing this issue. I'm using 4.1.1 Brazilian stock ROM here.
Even before flashing CWM (yesterday) I as going through this problem. Most times it happens when the screen is off.
Maybe changing the stock Kernel to a custom one would solve this?

[Q][Help] Phone constantly "reboots", stock firmware, have logcat!

Alright, so my girlfriend's Samsung Galaxy S II started to go through these weird partial reboots several weeks ago (maybe even months). The phone would randomly go black, play the stupid shutdown/startup (dont remember which) jingle...then just simply be at the lock screen with a crossed out circle where the signal bars would be (for just a couple of seconds). When this happened, I used to just tell her to shutdown the phone, take out the battery, and let it sit for about 30 seconds, then put everything back together and start it back up. This seemed to work, which made me think it might have just been a software or at worst a memory issue of some kind.
This issue was always intermittent, but now, no matter what I do, it just keeps looping this "restarting" problem. I can't access any internal memory space from my computer because in the time it takes to connect, it just "reboots" again. I made a logcat of the phone up until the "reboot", and in doing so noticed that when I would browse the phone via adb shell, I saw no mount for the sd card...which then lead me to believe maybe it was an issue with that. I checked the sd card for corruption (and prior to even using it, checked that all blocks were read/writable (legit)), but that led nowhere.
Anyways, not having any idea where to go next, nor where to begin or what to look for in the 5000+ lined logcat, I turn to xda with hopes of getting some sort of help. Thanks in advance for any I get!
EDIT: Oops, some other important notes I didn't mention (other than in title); this is running stock firmware, only OTA. I tried once to upgrade her to ICS via Kies, but the upgrade would never complete. She also refused to let me root her phone...so unless there is a stock recovery mode, her phone has none...

bump, as its been a week and no responses. If anyone has any ideas or can figure out whats wrong from the logcat, please help.

Almost 3 weeks...no answer...isn't there at least 1 person who has an idea or can deduce one from the logcat? Pretty soon I'm gonna have to tell her to give up and get it "fixed" (ie, swapped for a refurb with most likely all her data lost)...

Looking at the logcat if it is accurate the problem is overheating and it is shutting itself down. That's why it keeps rebooting from I read but I could be wrong. Also looks like it has wakelock issues. Lot of wakelock errors in logcat. Some app or apps are causing the wakelock issue find them and remove them that might solve the problem.

i say try to odin back her phone to stock on here there a good post for it to get her back and if she had Gmail sync there shouldnt be a problem unless she really dont want to download everything again i say give odin a shot and then from there upgrade through kies its tricky you have to make sure you have 50% battery life or more and kies errrors out sometimes but it does work i update my friends phone as he does not like all the root stuff lol so i always your kies after a couple errors it will work and thats your best option if she doesnt want to loose anything kies will back it all up for her and are you sure that power button aint sticking sounds like you have a looping issue are you able to go into download mode or are you familiar with this ?

Idk how to read logcats but another idea could be you have the sticky power button issue. I think if it was overheating u would feel it and mention it in the op.

I used to have this problem when my phone was on ICS. I found that putting it back to GB, and using custom JB roms fixed it. I'd try those.

For starters, thanks everyone for the responses! After this long, its really great to see so many in one day!

Thats what I thought, because it seemed to get exceptionally hot before "rebooting"...at first...then I was noticing it "rebooting" when clearly cold. If it is indeed overheating like I had thought in the very beginning, is there anything I can do about it? What does it use for heat conductivity and displacement? And for that matter, I would think if it was overheating though, it would actually reboot, not the half-ass semi-reboot its been doing...
And what is wakelock exactly that it would cause an issue? Only apps I see using it are WootWatcher, KeyguardViewMediator and PowerManagerService.

I would use odin...but the phone doesn't stay on long enough to do much of anything before "rebooting". Also, she is already using stock firmware + OTA updates. And her contacts are not what I am worried about, its her photos and such. This is the very reason why I hate internal memory for phones...
And I'm pretty sure its not a sticky power button, I had seen that being a common issue when researching before posting. And again, if I have not been clear, its not exactly "rebooting", just semi-rebooting; phone starts up, crap starts running, a min or 2 later, phone acts like its restarting (plays sound and all), then just comes back to the lock screen immediately...I can't really describe it much more than that.
And no, I'm not familiar with "download mode"

Ya, like I said in the reply above this, I don't think its the sticky power button problem...but I could always be wrong. I only didn't mention over heating because I felt I did a good job of ruling it out.

Its running GB atm, never updated to ICS via Kies...

I wish I could help you further but i can say one thing, the rebooting that your describing is called a "hot reboot". I know what ur talking about and others will too if u use that term. Good luck.

Am I the only one whose GN2 locks up every once in a while?

I've been having gn2 from at&t for about 2 months. It's awesome in most respects but it sometimes locks up cold. By cold, I mean that the only way to fix it is to pull out battery for some extended time - 5-10 min. Usually it happens when I use some software, typically accessing network. Just now it happened when I used Chrome beta.
Also it happens sometimes after graceful shutdown that it locks up immediatelly on boot.
Seems to happen with any rom that I tried.
Does anyone else have similar problems? I wonder if it's hardware defect.

I was experiencing lock ups on earlier 7105 ROMs I was using. I thought power cycling was the only way then I discovered if you take out the S-pen (and then put it back) it would unfreeze the device. Maybe give that a shot next time, in case its similar.
Mine would freeze randomly...

I have never had a problem with mine, but it is still stone stock. That will be changing shortly tho...

I haven't had any lockups per se, but I've had 2 random reboots. I've had the device a week. Rooted, on stock.

I've had this phone for 5 months roughly. It has never locked on stock, Clean ROM, CM 10.1
It really shouldn't be locking up ever

Mine used to do that. Turns out the problem was Superuser. If you have Superuser, and not SuperSU, installed, try switching them and see if it clears up the lock ups.
I would also get weird notifications about "shell" and "radio" trying to get root access.

I had this problem on my SII.

My girl had this problem as well. To remedy it first I wiped the external sd card. Wiped everything off of it incase of some bs data.
Then I wiped and re flashed the rom and only restored mms and the call log with tibu. The rest of the apps she had I manually installed them one by one from the market.
Now doing the above two cleaned up a lot of lockups but it was still happening. Final thing that actually stopped the freezes was getting rid of Chrome. Why was Chrome causing issues, I have no idea but after removal the phone never randomly rebooted and after getting use to the stock browser it's been smooth sailing.

Edit: sorry just for reference both my phone and hers are running SkyNote 6 with the 6.7 update and the saber 13.4 release.

Chrome definitely may be a culprit. It happened to me often when using it. What is interesting is that it wouldn't reboot unless battery is out for few minutes. It feels like some memory state , perhaps in modem, gets corrupted and isn't cleared during boot.
And it was happening at times with freshly flashed rom with full wipe.

I have this issue too. I know for sure it is ROM or Kernel related as it never does it if I revert back to stock ROM and Kernel. Mine seems to be in a really deep sleep when it happens. I hold the power button for about 15 seconds and the phone reboots and everything is fine for a few days again.

[Q] Galaxy S III behaving erratically...malware??

Hey all!
I haven't had much to post about my Galaxy SIII (Sprint) before till recently.
Lately I have noticed that the screen locks up. Doesn't really seem to correlate with what I am doing, but it just freezes. Sometimes I get a black screen if I start an app and sometimes it is when I pull down the notifications screen. I have seen this described before but no real suggestions on how to fix my device from freezing several times a day.
Today, The phone icon in my lower tray keeps disappearing.
Also, the phone dialed itself (the last number I called) and froze so I couldn't hang up the call! I had to do a battery pull!
Not sure what is going on with my phone, but it is time to call in the experts.
Could it be that I have some sort of malware? Is there even malware for androids? Do any of the programs work to remove it??
Any suggestions would be really appreciated!
Thanks all
Mike

Are you on a custom ROM, or rooted, do you have custom recovery if so which one? Can't really help you by what you posted. Unless you are downloading 3rd party apps that aren't from the play store its probably not malware. Here is a malware app to run though https://play.google.com/store/apps/details?id=com.lookout

Yeah. +1 on this 100%. Google screens the majority of apps and they're constantly on the look out to make sure apps arent messing with your phone in a way that they shouldn't.
I've said this many times in many threads and I will say it again here.
The best anti-virus is an observant end-user. Just watch what apps you install and what permissions they ask for (for example a game app doesnt need access to your contacts) and you will be good.

So wait, I shouldn't install this file I found off of Google? It's filename is: "totally_not_a_virus.apk"
Sounds legit to me!
But yeah, to OP, it sounds like you might want to do a clean flash of your room and see if that helps.
