Nexus Rebooting Randomly

Its happened twice that i can remember now.
This morning in bed I grabbed the phone, deleted some emails, opened the browser and the screen went blank with the sound of a slight crackle. It then instantly revooted (google logo popped up etc).
Im concerned the phone is faulty. Is it likely just one of those things or does it sound more sinister?
Hope somebody can advise.

Mine rebooted once the other day. I don't necessarily think that the phone is faulty, it just has bugs that need ironing out.

it's just the apps
it can happen with any android device
just keep an eye on which app is causing it
you can pull out the logs and scan through it

I've been having the same thing as the OP. I get "Android is Upgrading" when it restarts, too.
In additiona I've seen (several times now) that when I press the power button to turn the screen on, it wont accept any input. After 30 minutes or so it spontaneously restarts and goes to the "Android is Upgrading" message when it restarts.
I'm on the verge of RMI'ing the thing as some of the other guys in the office who have it have not had the same problems.
I'm running vanilla sim free version, no operator tat installed.

Are you running a totally unmodified stock rom or have you flashed a custom rom/kernel/radio to it? Kernels are still being worked on and arent perfect yet.
Also Android 4 is still very new and alot of apps are not fully compatable and subject to crashing or crashing the system.
Everything will be ironed out in time

[VZW] Phone Random Shut Off?

Hello everyone,
I've recently rooted and unlocked my phone in order to partake in some Jelly Bean goodness. I've read and done the nandroid backups/cache wipes/dalvik cache/factory resets, and have flashed my first ROM (Vicious 10-20120808-UNOFFICIAL-toro 4.1.1). The installation went smoothly, and the phone was working great until a weird problem happened.
I was texting on my phone, put it down, came back to it a few minutes later and the screen was completely off, and it would not respond to the power button. In order to get it to work again, I had to remove the battery and place it back in for it to respond normally. Upon doing so it would boot back up normally and I'd be golden, but now I'm noticing it is doing the shutoff again every few hours when its idle.
Any ideas for a fix?

I am having the same problem. Went backdown ICS for now. Have you found a solution. I was using the JRO30 JB build.

Happens sometimes to some ROMS. I have no idea why it happens, but its nothing wrong with the phone itself. I recommend AOKP for awesome battery life, performance, and features

Please help!! Phone reboots randomly even on complete stock unrooted.

Okay, I've had my S3 since July of 2012. It has worked perfectly up until about 3 weeks ago. It has just started rebooting randomly and it says it's not sending texts, but the people I'm texting say they receive the message that supposedly fails to send like 5 or 6 times. I've spent the last 2 weeks trying to find a solution online and couldn't find anything. I have flashed probably 15 different roms, including stock rooted. Now I am on complete stock unrooted with stock recovery and I'm having the same issues. I used odin to return to stock. I only have 4 apps installed aside from the bloatware that comes with the phone. I'm sure the texting issue is with T-mobile's service, but the rebooting can't be. It's random, but I can always tell when it's about to do it because the screen will come back on right after I lock it and a few seconds later it will reboot. I have also taken the phone apart to see if the power button is jammed and it wasn't. I removed the actual power button and put it back in just to be sure. The phone still reboots randomly. Is anyone else having this issue and if so have you found a way to stop it? Any suggestions will be appreciated. Thank you for looking.

I guess nobody has had these issues.

Sounds like a defective phone.

It would of been easier if you had warranty on to just return it instead of going through all that hassle.

I have the same issue, pretty sure its the power button sticking. I'm using the home button to wake it up and a widget on the lock screen to lock it for now until I send it in.

It stopped. I don't know what it was, but I ran stock for a few days and it just quit. Didn't do anything, but flash it back to stock, It did it for a couple of more days after I flashed it back to stock and then it just randomly quit. It's been almost a full week now and no random reboots. If it starts happening again then I will probably just get a replacement. I do have the insurance through T-mobile, but I don't want to pay the deductible.

Could some dust etc. making power button stuck causing reboots? It could also be unstable rom. If you are oc/uv 'ing the phone that could also do that

I had a similar problem with my Amaze, turns out one of the connector pins to the battery was miss aligned and would on occasion cross the line and short. Luckily nothing catastrophic but the phone would just reboot, sometimes continuously. After I straightened it out, problem solved.

I'm actually having this exact same issue, as well as crashes which seem to happen when copy/pasting text. Reboots, spamming people supposedly failed messages, the works....
And I'm with Sprint.
This is the SECOND S3 that has done this to me. I returned my first one after being fed up with it, guessing it must have been a hardware problem since I couldn't find anyone else that had this issue.. but this one has done it too, so I just figured I had to accept it....

phsh I wouldn't accept a piece of hardware that acts like that... bug 'em til they fix it or get you something else like the s4

Interesting to read this. I got my S3 in October, and it just started doing this. Twice it has simply rebooted, both times have been after I uninstalled an app. My phone is completely stock, unrooted. Never been rooted. I took it out of the box and updated it to JB and haven't done anything else. I'm not getting any messaging issues, just the reboots. I'm using Nova Prime, and uninstalling by dragging the icon to the trash can.

I'm not sure what caused mine to stop, but it did. It hasn't done it again since it stopped either. I flashed back to complete stock, unrooted and used triangle away. It was still doing it for maybe a week or two after that, but then it just stopped. It has been working fine ever since. That includes trying 4 or 5 different roms after it stopped just to see if it would do it again. Been running wicked on the same phone for months now without any of the issues I previously had. If your phone is doing this then I suggest either waiting to see if it stops on it's own like mine or get it replaced.

[Q] Nexus 7 stuck on Google screen, reboots and freezes?

Hey, everyone. I know this issue has been reported before, but NONE of the solutions are working for me. Perhaps I just have a bad Nexus.
I received the device for Christmas and it has worked perfectly fine. Super fast, fluid, responsive. Then, suddenly, I was using the device and it randomly rebooted. I thought, "whatever, this happens to all devices at one point or another". But then, after I turned it on, it got stuck on the Google startup screen for at least 5 minutes. I decided to restart and try again, but this time, it got stuck on the google screen, rebooted on its own and got stuck on the google screen again, repeating this cycle over and over.
So I went into Recovery mode to wipe the cache and do a factory reset. Not even this would work. The factory reset worked, but when I started up my tablet again, it froze at the Google screen. Eventually, it would just continue the cycle of freezing and rebooting. This is ridiculous. A brand-new, unrooted Nexus 7 on 4.4.2 should not be completely unusable. My warranty is up on the 18th, so I will probably just return it, unless someone has an idea.
Thanks.

That'a your best option. If you haven't modified it in any way then use your warranty.

I agree. Since you did not root it, there is probably something wrong with your tablet and you should get it exchanged while you can

I am going through the EXACT same thing and no one has been able to help.. What I did to fix it was re-flash the 03.15 bootloader and that allowed it to start. I think there's some tablets out there that "don't like" the new bootloader included with the KitKat update and I'm glad to see that it's not just me... At least you are able to return yours. I purchased mine back in August last year

At&t Note 4 Keeps Freezing And Rebooting Randomly

Hello Smart People,
I have an unlocked at&t note 4 and for the past 2 week my phone will freeze for 1-2 minutes then it will be useable again or if it is not doing that will randomly reboot when I am using the phone. So benging of last week I called tmobile since I have them now. I spoke to tech support. Told them my problem and they had me turn off the phone and take the sd card out and then boot into recovery to clear the cache. That did not work. Within 5 minutes of have the phone back at the home screen it froze again. So tmobile said that it was not the sd card in the phone. Told me to turn the phone off and put the sdcard back in the phone. Then I rebooted back the home screen. They said that at this point all I could do was back the info on my phone and do a master factory reset of the whole phone. I told them I could not do it right then and there. They said if it still happens after the master factory reset then you will need to get the phone reflashed to have the software fully reinstalled and they could not do the reflash of the software since my phone was an at&t branded version of the note 4 so I would have to call at&t and see if they could reflash it for me. So the next day I backed up my phone using samsung smart switch software on my pc and master factory reset the phone from the recovery menu. When it was done I resetup the phone and it still froze and reboot randomly. So I called at&t and spoke to tech support and told them my problem and what tmobile say to do. They told me they could do the reflash but since I am no longer a customer they was nothing they could do for me. But I could go to best buy to a Samsung experience store and they could reflash my phone with for me with the latest software that at&t had out. So I went to the Samsung store inside of best buy. I told the lady my problem and what tmobile had me do and what at&t told me. She told me she could do the reflash but I already had the latest version of the at&t software on my phone all ready. I told her that tmobile told me the hardware in my phone is all good and that however I got the at&t update it did not apply correctly and that I need a reflash. She took my phone and started to plug in to her computer to do the reflash. After it was done she gave me my phone back. On the screen it was in recovery mode trying to reboot back to the phone screen. I showed the phone to the Samsung store lady and she told me I had to wait and it would reboot to the home screen. I thanked the lady for helping me out and left the best buy store. Got to my car and the phone now had a black screen so I took out the battery and put it back in and turned on the phone and it booted in to recovery mode not the home screen. From the recovery screen I picked reboot the phone and once again booted to recovery mode. So I walked back in to best buy and talked to the Samsung lady and was like this is very weird it should not be doing this. She also took out the battery and put it back a few times. Still phone was rebooting to recovery mode and not the home screen. So she called her tech support to figure out how she could fix my problem since now my phone was 100% not useable. The Samsung lady’s tech support had her plugin the phone to the computer again and reflash the software. But it failed at 3%. She was told to tried it again it failed at 20% this time. So she was told try it again and it failed this time at 50%. So she was told to try it one last time and this time it went all the way to 100% and she keep the phone connected to the pc until it was fully rebooted but again it rebooted to the recovery more screen not home screen. She told me that she would have to keep my phone and next day ask Samsung for the full flash of the software to download for my phone since she only had the latest update. So I left my phone with her and waited for her to call me and let me know that my phone was all good to go. I went back the second day after giving Samsung my phone and the lady told me that she did not run the full flash because she came in the first day after I give her my cell phone and it was at the home screen. I thanked the lady and left the best buy store. When I got home I download an app from the google play store and the phone rebooted on me. So the problem is still there! The phone so far has not frozen on me which I guess in grand scheme of things is good, but I am not calling this over just yet. So smarter people of xda Is there anything I can do to fix this phone so I can still use it and not have to worry about it or is it time to just bite the bullet and get a new phone even though there is nothing out that I like.

We're in the same boat
I am having the same exact issue. I just got my phone flashed at the Samsung experience kiosk at best buy only to use it and find out it still randomly slows down then crashes and restarts. It at times crashes as its restarting and continues a boot loop for a while. What can be done?

1.Battery is about to die or 2. Uninstall good luck

I'm having the same issue with my ATT Note 4 it started a couple weeks ago as well

Was in the same boat
Install a app called WakeLock from the play store. Use the level 4 option and yours troubles will be gone.
I had the same issue for 2 weeks and then came across this gem on one of the forums. Has not caused an issue for the last 2 weeks now.

Is that app wake lock powermanager be Darken? There are a few wakelock apps.
I'm in same boat as well. NOTE 4 worked great until a few weeks ago. Then MANY freezes, reboots, etc. I almost think aTT pushed something down intentionly (ita called planned obscellesence) to force an upgrade. Not reall5, but I do wonder .

Worked like a charm!
Edit. Worked for a while but apparently my battery was trash. New battery came yesterday and solved all issues i was having.

WOW! I was ready to throw my note 4 in the garbage because of all that crud! This app is AWESOME and did fix my issues. Thanks a ton for those that recommended it. My note 4 runs wonderful now, and probably will be PLENTY sufficient for me for another 2-3 years. Unfortunately, this issue has REALLY dampened my outlook on SAMSUNG and cell companies for that matter. It's in their best interest that people DO upgrade phones every 2 years or so.

Help please
Brother I have a problem, I upgrade my computer to Marshmallow 6.1.1, but to days if I used the camera, the phone was turned off and I had to remove the battery and by odin I downloaded it to version 5.1.1 but now I reboot Every time, it overheats, if I restart the phone does not turn on if I do not remove the battery the same I turn it off, try to install version 6.1.1 but do not leave the rescovery mode and install version 5.1.1 but with the Failures that I just comment. IF YOU CAN HELP ME THANK YOU

battery issues

Just want to say was about to throw out my note 4 this week for the same issues. I installed the wake lock app (darken), have it set on 'partial wake lock' and AMAZING my phone seems to be operating normally! Thank you, and spread the word.

Wow! Thanks to all for the great tip. You saved my Note 4!
Since the latest OTA ROM upgrade from AT&T, (6.0.1, baseband N910AUCS2EAK5) my normally solid note 4 phone worked like garbage! It would slow way, way down, especially on a strenuous task, and quite often reboot spontaneously. It was so frustrating, I had to carry a second phone just to make sure I could be reached.
I did everything - wiped cache, factory reset and was just about to ODIN flash an earlier ROM when I can across this tip on XDA. This Wakelock app is phenomenal!
It seems as though Samsung / AT&T released the last patch with faulty power management. This app bypasses the whole issue by NOT allowing the phone to enter deep sleep. Problem Solved! Perhaps battery life takes a small hit, but who cares! We just have to hold on until the Note 8 arrives!
---------- Post added at 02:47 PM ---------- Previous post was at 02:39 PM ----------
Totally donating to Darken (via play store) for saving my phone from the garbage, and saving me $500 to upgrade to a phone I don't want! Best $2.31 ever!

Still need the app
I just did the OTA upgrade from AT&T. I am now on baseband N910AUCS2EQD1 (6.0.1) I was hoping this upgrade would fix the problems, but it didn't. Still need the app!

my daughters note 4 has been randomly rebooting and sometimes when it reboots it sticks at the att symbol or it even goes to download mode? it started after att did a update . i told here to try the wakelock and let me know how it goes but has anyone had it reboot where it says could not reboot then has the android and do not shut off target?

Would anyone happen to know how well Wake Lock plays with Good Lock and/or power saving mode? My battery is ready to retire (seems to be at about half-capacity if that's the right terminology, new one on the way) and I've been having these freezes and reboots happen to me over the last few weeks; often at annoying inconvenient times.
My new battery should be here before this week ends, but I'm just looking for some insight for the few days in the interim. Thank you in advance for any responses​.
...Noted (SM-N910A)

well tried wake lock and it seemed to help but did not fix the problem, phone was flawless and worked perfect before 6.01 . now reboots during call and downloading updates from playstore ect. sent it to samsung and they said it would be $70 to repair so i sent it in. they called and said the screen has ghosting and need a lcd, i think they broke it and didnt want to pay for it but they had it and i had to get it fixed. i now have it back with the newest att rom and updates with a new motherboard housing and screen for $185 but it works perfect like it did before with 5.0 so there is a hardware issue gong on with certain boards from what i have been reading in other forums its the early production ones. must be ram or internal sd who knows but whatever it is the marshmallow rom brings it out. did not want to spend the money but it was worth it. no lag and very snappy again and no reboots. i wish samsung would admit there is a issue with the note 4
