Random reboots - Samsung Galaxy Nexus

Im new in this nexus section...i'm asking why my galaxy nexus sometimes reboots? It has the latest 4.2.2 android version stock...it isnt the update, i think, because also before this happen...and when it reboots there's like a opened locket under the google logo....who can help.me? I tried also the nexus toolkit...but when i try to do something with fastboot the program says WAITING DEVICE forever...

Guys, please help!! Its really urgent!

Hi,
I think there are two reasons for random reboots:
1- overheating
2-lack of ram (many running proceses, so ram gets full, so it reboots.
Press the thanks button if I helped

No, even when the battery isnt hot it reboots!!
and it is without any apps installed, only stock apps!! I did also a factory reset from settings..but nothing happened...
Searching on net, i read that the opened locket is the bootloader....is that causing random reboots? If yes, how to relock with toolkit? Beacause it says me WAITING DEVICE

No, unlocking the bootloader shouldn't do this. I have an unlocked bootloader, and I have this phone(xperia arc) for 5 months and I only had one random reboot and it was definitely because of lack of ram

Yes but im talking about NEXUS and maybe its different!!

I used to have that happen all the time. I used to think that the phone sucked but my husband never had that happen with his. I compared the apps and wiped my phone, only installed what he had on there. It still happened. I was really beginning to get mad but I wiped it again. I Installed things one by one only allowing myself to install a new app only after it had gone a week with no nonsense. Yes, this was a painful process but I found the cause of my random reboots. I use Handcent. That alone isn't the cause. When I would get new sounds for my GN, I would have the option of making them a ringtone or a Handcent notification among other things. If I made Handcent notifications, that seemed to cause the problem. If I move a sound into the notifications folder and assign it to contacts in Handcent, everything has been fine.
I don't know if this helps your problem but some settings could affect unexpected things. Good luck!

I did factory reset twice from device's settings, but nothing.

no one who can help? wow!!

I had random reboots on my Verizon GN running the OTA 4.1.1. I got so fed up with it that I went back to 4.0.4. I have had no problems or reboots since doing this.

Are you running Chrome or the stock browser? I've always had the random restarts on my N10, but only started seeing them on my GN after I started using Chrome around the time 4.2.2 came out.

OP, read the return to stickied thread on general forum by efrant, if your problems still happen after restoring back to stock through fastboot, then you may have faulty hw.

[Q] Issue after ICS update - Phone freezing

After the ICS update on my non-rooted phone, the phone seems to be freezing
up and becoming unresponsive. After a while it looks like the radio "resets", all
the icons disappear in the top bar (signal, wifi, data) and it shows no service.
Then slowly one by one they all come back and I can use the phone again.
Sometimes I receive the "System is not responding" dialog box, but not always.
There is not one particular program it is doing this in, it can be something as
simple as pulling down the notification bar that will cause the freeze.
Any suggestions are appreciated, I couldn't find anyone else with the same issue.
Thanks.
Try:
Turn off phone
Take out SIM
Put SIM back
Turn on
I've had my phone act weird with respect to signal, wifi and data when this was the issue. Worth a shot, at the very least.

Thank you for the response.
Tried this and had the system is unresponsive issue right on reboot. If I do a
factory reset, does it reset to the current firmware or what was originally on the
phone (probably a really stupid question). I wonder if some other program isn't
ICS compatible and is doing something in the background. Doesn't look like
anyone else is having this same issue.

If you do a factory reset and it was the standard Kies legit update from Tmo, it won't downgrade your phone - will just re-install a fresh copy of your ICS. Did you do a restore of apps from your last version (gb?) with data? That could cause problems I would think..

Yes I did the legit update on Kies, standard stock phone un-rooted.
Do I need to backup pictures before the reset, its been a while since
I had to do this.
At this point, I think its worth a try to wipe it clean and clear out all the
data.

wipe the dalvik cache and cache then reboot
I did a factory reset and that solved the issue.
Thanks for all the assistance.
I've done a factory reset and wiped the cache more than once already and i still get a force close or unresponsive, enough that its really irritating me now. Any advice? And also, when texting, the typing responds very slow.

Are you letting it sit for like 10 minutes during first boot after factory reset then reboot again before setting up. Its likely that some scripts are running from the initial installation and you need to let it rot until its done..
I did exactly that, thanks for the advice. Hoping that may fix the problem. I wiped the cache and factory reset, then let the phone sit for a good while before going through the play store and re-installing everything.
This issue just resurfaced again. The last 2 days I am getting the freezing, radio reboot and android process not responding.
No one else having this issue?
I think I'm in the same boat. I was stock GB, and just did the mini OTA update (which was great). A few days later ICS became available via Kies from T-Mobile, and I "upgraded".
Since the upgrade my phone is laggy, screen is significantly less responsive and also my battery life is less than before.
I have NOT done a factory reset of my phone yes (plan on doing that today), but even with that I have read that performance does not improve.
Ideally, I would love to return back to the stock tmobile gb firmware. However, even after literally 2 hours of reading I can't find the "how-to" and files I need.
I would appreciate any assistance.
t989 chip lags
ive notice this happen on my tmobile galaxy s2. i think it has to do with the Qualcomm chip on tmobiles stock roms.
When i had sprint i bought my girlfriend a galaxy s2 on the sprint network which runs the samsung exynos chip. She never complained about any lag or freezing whatsoever. I then left sprint because of their garbage network and joined tmobile.
bought 2 galaxy s2s and i noticed the lag almost immediately. The phone has random lag spikes as well as freezing and force closes. It had it on stock gingerbread and it has it on stock ICS too.
My girlfriend complains about freezing all the time so i decided to root her phone too. Right now im testing DarkSides v7 rom and if its pretty good in performance i will flash her phone with it too. So far it has been pretty snappy and everything works.

Because you are on stock ics (im guessing you are..), you can just follow that guide and flash the UVLDE update.
Yes clock resets to standard standard time.. I already did a factory reset and worked done for a couple weeks. My wife has same phone and she is getting the freeze ups now.

Thanks for the suggestion, I'll give it a try. But it really shouldn't be necessary on a phone that's got more going for it than the stock nexus that 1st came out with ics.

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.

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.

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"

Random Reboots since JVB by OTA

This has happened to me twice while in my pocket since receiving the OTA a week ago. This never happened with ZV9 since getting the phone months ago.
Has anybody else seen this? Any ideas what this might be? Any apps to help figure out what's causing this? Is this related to the location service reboots that other phones on Jelly Bean like the Nexus were having?
I am not a big fan of Android version changes via "patching" for this very reason. I suggest doing a factory reset and see if it continues to happen.

Good call, thanks for the input. I was considering doing that if it keeps up.
I'll probably root and unlock soon anyway once I have some time.

I had this problem and it only happened after I had updated the Android Booster FREE app. I uninstalled Android Booster FREE (as it really wasn't useful, in my opinion anyway) and the problem disappeared. If you have this app installed maybe you can uninstall it and see if that solves your problem.
Thanks for the input, but I never use any apps of that nature, and no power saver apps either.

[Q] Random Reboot

Hi,
History:
I have a problem with my Nexus. It randomly reboots. Nothing seems to help.
It started after a few months after I was rooted on CyanogenMod 10.0. In 3 days, it quickly escalated to a reboot every 10 minutes on average.
A factory reset (without user apps installed on it) on CynogenMod reduced the frequency (every hour?), but didn't eliminate it.
Unrooting to stock Jellybean 4.1.2 seemed fine only in the first week. The problem came back afterwards, and updating to JB 4.2.1 didn't help.
Now, 2 months on stock ROM, I get even more random times. Sometimes it is 2 times a day, sometimes once a week.
Just before it:
I get a metallic screeching noise for 1-2 seconds, and immediately following that, device turns off with a "pang". Although these days I HAVE had situations that the sound came for up to 3 seconds (and the screen freezes), but the phone worked normally afterwards.
What happens:
It randomly reboots. The rebooting is at irregular intervals, whatever i was doing on it (even when not using it).
What happens after:
It takes much, much longer to startup again. It can get stuck at the "Google" logo screen for up to 5min. It doesn't take this long to reboot if I shut it down myself.
Any ideas? What causes this? Is it software or hardware?
Can I even send it for warranty if I cannot reproduce the problem?
I don't want to send it to warranty if I don't have to. I don't want to loose my phone for I don't know how long.
Hi, what's your eMMC version? Maybe buggy memory, try looking at other threads.

I'm new to this eMMC thing, but according to an app my eMMC Type is V3U00M. To check whether it is buggy or not it needs root, which I don't currently have. If it IS buggy, I don't have a choice but to bring it for warranty right?
No, I have not tried to changed batteries. I don't have other batteries. But can the problem really lie with the battery? Btw, my phone is less than 8 months old.

Well, I am planning to root again. I want to switch back to CyanogenMod 10.1. Lagfix app isn't needed if you can use -discard mount option right? How to use either, if let's say I'm on CyanogenMod. This is also the first time I hear of lagfix and discard mount... :/
Btw, the app i used to check my eMMC Type said that my chip is ok. No brickbug. Are you sure it's buggy?

I might be wrong here, but from what I've read at the link and other xda posts (http://forum.xda-developers.com/showthread.php?t=2029246), the V3U00M chip is not buggy (in the sense that it's stable for rooting and using the -discard command), but it does give slowdowns. I do have horrible slowdowns, so thanks for that solution I didn't know existed. However, this doesn't solve my random reboot problem at all...
No one else got any solid way to find out the source of the problem?

Hi,
History:
I have a problem with my Nexus. It randomly reboots. Nothing seems to help.
It started after a few months after I was rooted on CyanogenMod 10.0. In 3 days, it quickly escalated to a reboot every 10 minutes on average.
A factory reset (without user apps installed on it) on CynogenMod reduced the frequency (every hour?), but didn't eliminate it.
Unrooting to stock Jellybean 4.1.2 seemed fine only in the first week. The problem came back afterwards, and updating to JB 4.2.1 didn't help.
Now, 2 months on stock ROM, I get even more random times. Sometimes it is 2 times a day, sometimes once a week.
Just before it:
I get a metallic screeching noise for 1-2 seconds, and immediately following that, device turns off with a "pang". Although these days I HAVE had situations that the sound came for up to 3 seconds (and the screen freezes), but the phone worked normally afterwards.
What happens:
It randomly reboots. The rebooting is at irregular intervals, whatever i was doing on it (even when not using it).
What happens after:
It takes much, much longer to startup again. It can get stuck at the "Google" logo screen for up to 5min. It doesn't take this long to reboot if I shut it down myself.
Any ideas? What causes this? Is it software or hardware?
Can I even send it for warranty if I cannot reproduce the problem?
I don't want to send it to warranty if I don't have to. I don't want to loose my phone for I don't know how long.

Same as you man...
I'm seriously considering throwing my phone to the garbage. I don't like iPhones, but google is really pushing me into it with this crappy piece of phone. Is so frustrating to have these rebooting issues, I've tried everything, from wipe to factory reset, back to stock, flash custom ROMS and KERNELS, turning location access off, uninstalling all apps/widgets that might interfere, and every single "solution" it's out there, and STILL I'M HAVING THESE DAMN REBOOTS!
Now it's even worse, I can't even transfer files to my phone anymore because, guess what... IT REBOOTS! everytime I transfer ANY KIND of file.
The only thing that seems to work for a while is reformatting and start from scratch. I've done that like 3 times already. But still after a few weeks the issue reapears... i'm really mad about this, and no one seems to care. Not Google and not even Samsung.
The only interesting thing that i found around the internet is this guy's findings

I read the log on my phone and matches to his... but now the thing is, what do i do with this information? I'm not a programmer o something like that.
Any ideas?
I think your board is faulty. Even so, have you tried disabling SR and raising voltages across the board? Trimming eMMC? Omapflash?

Hey! Thanks for the reply but I'm just a regular user with just a little bit of computer knowledge... so the things you mentioned are basically Chinese to me

He is saying that you have root you need to install trickster mod from the play store. Open the app and go to specific. Then disable the smart reflex toggles and click the oké button in the upper right corner see if that works. If it doesnt re enable smart reflex and go tot MPU voltages. Next to the words MPU voltages there is a blue plus/minus button. Click that and click the plus one time. Accept it and push again the oke button. The other two things I dont exactly know..

Honestly, if you are getting reboots on a clean stock (including stock kernel) , it's probably a hardware issue.

I tried both things you mentioned with no luck
I'm still searching around for those other things beekay201 mentioned earlier. I found that Omap Flash is a tool for flash roms in binary mode, so that way you can unbrick some phones. Still trying to find out how that can be useful for my case (forum.xda-developers.com/showthread.php?t=1242330)

The thing is that after a clean stock install everything works fine for a week or two, that means no random reboots, and i can transfer any kind of file of any size with no problem. Then for some estrange reason (even with no crazy apps installed) starts with a random reboot, after that first reboot i know is time and that i wont be able to transfer files anymore, because it WILL reboot while i'm transfering files. Other thing i have noticed is that around where the camera lens is, get really hot. So I think that the reason it reboots is kernel panic caused by overheating, or the other thing is that my sdcard have some issues when writing files.
Right now i'm using CyanogenMod 10.0.0-maguro with jelly bean 4.1.2 and franco.kernel 3.0.51-nightly-512GPU and i have already tried going back to stock.
how can a I check if my hardware is fine? Is there any app out there?
Thanks!

512GPU? You mean your GPU is overclocked? Maybe try to set your GPU to stock. And if it gets really hot and you have random reboots you can try to over volt with trickster mod.

No, I don't think my GPU is overclocked, that's the full name of the kernel, you say that the kernel automatically puts my GPU to 512?. Anyways i just installed that kernel two days ago just because i thought it might make the reboots go away. I'm having rebooting problems since february (just after upgrading to 4.2.1), so i don't think that the GPU is causing the reboots.

Well if it keeps rebooting you can try to over volt. Maybe that helps.
