[Q] automatic random reboot

hey all,
i got my galaxy note now 3 weeks ands it's rebooting random all the time. at a service point i let them do a factory reset but that did not work. does anybody know a solution for this problem? because i dont like to send my note cause i will not have a few days sow if anyone got a solution i like to try it.
Gr Sven

Suffering from the same here
I think its related to one of the apps - I will start removing my installed apps one by one from tonight - Will keep you posted with the updates.
Also, if anyone out there had the same issue; please advice!

I had the same issue on previous android devices..I managed to get around it with numerous hard resets. Also I believe that a certain combination of apps will cause it too..but i don't know which ones. I've got a dell streak right now, and its been stable for a few months..having said that, it still randomly reboots once in a while but no where near the consistency it used to.

I had this problem too and it seems to be an installed app problem, particularly any that change the wireless settings in some way or apps that stall when accessing the external SD card at boot times.

this is exactly what happens to me guys, same problem.
Random reboot and this happens all around the clock, no matter if it is day or night or if the phone is in flight mode...
Frankly I don't want to uninstall my apps one by one to check what app is causing the issue because I have no time to spend on it...
I hope that someone with more software skills than me (I am just an user) will succeed to fix it...
cheers.

Do you have Dolphin browser installed?
If it's the case, don't search further...

What's the problem with dolphin browser? I constantly use it and never had a restart. Is OPs phone overclocked or undervolted?
Which rom and kernel are being used?

mine is also rebooting every once in a while for no apparant reason. Mostly when I unplug it from the USB cable but not always. This happened from the first day on. I never did a factory reset but considering it now since the SMemo app is not working anymore (no strokes are visible) and I am out of options.

Come to think of it, mine also reboots when disconnecting from USB storage mode. I thought maybe this was buy design? Maybe not!

Do you use antiviral software? Start by removing that. Kaspersky have messed up almost all my Android devices.

why would you need to pay anything if the phone is under warranty ?

I also have this issue, I found out that its the power button..

Dolphin is a well known app for causing random reboot, since SGS 2.
Not for all users but for many:
http://forum.xda-developers.com/showthread.php?t=1321612&highlight=randomly
But without Dolphin installed, I really don't know...

I think it's the SD card causing these problems.
My reboot problems all disappeared when I removed the 32Gb sandisk card. I replaced it with a 16Gb card and was very careful about which apps I installed on it. Now whether it was the card size/brand or the selective apps that resolved the issue I can't be sure. Having Dolphin's cache on the phone memory instead of the SD card might also be a solution.
But it's worth investigating if you have reboot problems with external card installed.

Hi guys,
As soon as I got my Note, I rooted it and flashed a custom rom. Never had problems with reboots so far.
So, for a change I though setting it beck to stock was a good idea, with the upcomming ICS update.
As soon as I flashed the stock rom with odin, and it was back to factory situation, the reboots start happening. Every 3-6 hours the Note rebooted. Got in contact with Samsung (NL) and suggested to execute a factory reset, so I tried that a couple of times. But no luck, the reboots keep happening. I thought maybe it was an hardware issue. I have no Sdcard, only my SIMcard, which was a bit warn out, so I order a new SIM. But still, the reboots keep happening.
Then I decided to root my device again and flash a custom rom (Rocket-Rom), and guess what? No more reboots!!!
I hope this helped.

To me, I think automatic reboot is somehow still acceptable. I experienced two times auto power off. Both were happened after I charged it over night, unpluged the charger and left it without unlocking the screen, drove to my work place, and found it dead
I'm only having it for 2 weeks and I haven't rooted it.

it maybe a usb charging issue which is causing so much grief to many note owners. Mine has a defective usb port and it makes my note go crazy, including reboots and makes the note think its charging when its not even connected to charger at all.

Using note since dec... Faced such problem 5 or 7 time whn my phn was nt rooted... But nw its working fine... Using rocket rom v 20...

Freezing and bootloops.

Anybody else having these problems? 2nd day to have it and it would freeze up and bootloop. At one point it was off for 2-3 hours and I couldn't get to fastboot. Finally I got it to factory reset twice and its doing fine for now. Unfortunately I'm on shift for 24 hours or I'd make Verizon give me a new one.

Could it be some app that you installed? Haven't had any problems myself with it.

Have you switched from dalvik to art?

I've had zero issues with bootloops so far.

Haven't switched to art and I doubt any nonroot app would cause bootloops. Who knows.

No issues so far here

none here

Had one this morning. Phone froze during a phone call, and then got stuck at the boot screen before the animation. Rebooted it by holding the volume and power button and it's worked since.

No problems here, have played games for several hours straight with no issues and have been playing with it all day.

Mine was solid for about 4 hours and its starting back up again. Maybe I have a lemon.

sounds like a defective unit or something.
i'd do a wipe, dont install any apps, see if it works fine or not. if it does, probably an app issiue. if you are getting problems even after the reset, its the phone.

Same issue here. Kept randomly rebooting, but only occasionally. Did a few factory resets, installing only essential apps each time thinking it was one of my apps that didn't play nice with Turbo (even though they played just fine with my Razr Maxx and Galaxy S5) to no avail. Last night, did a factory reset, didn't install any apps (nor did I update any of the pre-installed ones) and this morning, endless bootloop. I can't get it to stop. I'm really starting to hate this startup sound. LOL!

My phone locks up occasionally. Always restarts itself. I'm not sure what has been causing my phone to lock up but I haven't been able to pinpoint an action that is specifically creating the issue.

So I couldn't figure out a way to just power it down (all the usual button combinations just kept rebooting it, which then continued the bootloop) so I just figured I'd let it bootloop until the battery ran out. After about 3 hours of bootlooping, it just finally booted. I didn't touch anything. Weird. Maybe it's like a 4 year old temper tantrum, just let them get it out of their system and all will be better in a couple hours. Hahaha!

I have a phone that it's going this as well. I can get into recovery and reset but that didn't work. If I try to wipe cache the phone reboots and freezes which seems abnormal. I never had a phone reboot after wiping cache. I loaded the phone into fastboot and using RSD Lite I flashed the original software into the phone to no help. I did notice though that in the fastboot option that my baseband is blank. Might just be a bad device.? Does anyone know where I can find stock firmware 21.44 (that has the VoLTE option)?

I've had 4 turbos, latest one with almost no apps, and been waiting on Motorola for near 3 weeks for another device... Just about to sell the next turbo they send out... I've also had the same issues plus WiFi drops BT drops freezing lagging, and lately unable to receive voice calls and voice mail

With four turbos there seems to be more of a user error than system. you either disabled a needed apk, installed an apk that doesn't play nice, or you took an ota and havent completed an FDR. Its recommended and has been posted on here multiple times throughout this site/forum that always, always do a FDR with an update.

I'm not running any additional apks at this point and haven't since the second replacement device. Apparently, I just have good luck with this phone, that I now despise, and wish I could get rid of. I followed all the disable guides for what was safe, and I'm not sure what an FDR is, but if you tell me I'll give it a shot. Last replacement came updated as well. At this point this current model doesn't even receive phone calls, because it just doesn't work correctly.

[Q] Note 3 crashes/reboots about once a day

For the last few weeks, my AT&T Note 3 has started randomly rebooting. It can happen when I'm viewing email, when the phone is in my pocket, or even in the middle of the night when it is just sitting recharging. The rebooting is roughly once per day: somedays more than once, other times it can go over 24 hours. The problem seems to have started after I updated to 5.0. I have tried a factory reset, but the problem came back. I called AT&T support and they said that they've had a lot of problems with Samsung devices after the 5..0 roll out, with random rebooting, or the Bluetooth failing, or the WiFi failing. They said that they need to replace the Note 3, but because it is over a year old I must pay $100 for the replacement through Asurion (I have been paying the insurance fee).
Searching on line has not provided much on this problem. Does the AT&T comment make sense? If I need to replace the phone, shouldn't it be for free because the problem was caused by AT&T?
I'd appreciate any comments.
Note that I realize it could be related to an App I use being incompatible with 5.0, but I need to use my phone for work pretty much constantly, so troubleshooting which one (if any) is not practical.

Mine started doing the same thing about a week ago. Till then it was not having any problems with the 5.0 version.
They need to figure out the problem and push out a update. Otherwise it is like they don't care about us, unless we go out every year and buy a new phone !

Problem solved?
After trying a reset and cleaning checking the battery contacts didn't work, I looked for other patterns. It seemed to me that one of the most common times it rebooted was when I checked my email with the K9 email client - something that is always running in the background, and could have caused it to reboot when on charge overnight.
I uninstalled K9 and that didn't help - the phone rebooted after about 9 hours. However, since that reboot it has now gone nearly 48 hours without rebooting. Maybe I was right about K9 and uninstalling it wasn't enough - I should have also manually rebooted the phone.
The phone has been rebooting at random times, sometimes as short as about 5 hours apart and sometimes more than a day apart. It could be that right now I'm at one extreme and it will reboot randomly today. But if it makes it through tomorrow morning without rebooting then K9 was probably the problem.

It has now been over 72 hours since the last reboot, which does suggest that the original problem was the K9 email client, crashing and forcing a reboot on the phone after the Android 5 update.

Problem NOT resolved!
A few minutes ago, roughly 76 hours after the last random reboot, when I thought that the problem was resolved, I heard the reboot tone coming from my phone that was sitting on the table.
So, while removing K9 reduced the frequency of the reboot, it did not solve the underlying problem.

Use Titanium Backup and backup all user apps and data. Factory reset and reflash stock if you want to take the extra step. Use standard Google and Samsung apps for a while. Do not restore accounts or system data automatically. Removing and reconnecting accounts and clear data for an app in app manager are always good quick troubleshooting options. Restore apps as you need them, if you really need them. Favor stability over extraneous features.
.......................................................
Galaxy Note 3 - AT&T (sm-n900a)

Since I removed K9 and rebooted the phone, it has only rebooted randomly once in 5 days: this was at 72 hours, and now it has been up for 65 hours since then. Trying what you suggest would take weeks, given the current frequency of random rebooting. Plus, my phone is used for work constantly - I couldn't get by with just the Samsung and Google apps built into the basic phone image.
For the moment, I will just live with the phone as-is and hope that Samsung issues a new version of 5 soon.

Now at nearly four days since the last crash/reboot, or only one in seven days. At that frequency, it is certainly not worth the effort of trying to track down the secondary cause (it could take months), now that I know that K9 was the main problem.

It has been a while since I started this discussion, with no conclusion. The phone still randomly reboots - only once all of last week, but then it woke me up on a reboot at 4:30 am this morning, and rebooted again while I was checking Facebook at 7 am.

I'm having a rebooting issue as well with my Note 3. It started about a week ago and will do it many times during the day. I have tried wiping the cache partition, doing a factory reset and the other day I downgraded the software from 5.0 to 4.4.2 and rooted it and froze the over the air update from AT&T but still have random rebooting. I have had the reboot issue with and without the SD card installed so I know that is not the issue either. I was thinking it was a software issue so that is why I did all of the stuff listed but now I'm wondering if it could be hardware. I guess I'm just at a loss of what to try know and was hoping someone on here had any suggestions.

I hope that with your additional post that we'll get some answers. One thing: does it happen when sitting idle on charge too, or only when not sitting idle? In the later case, it could be a simple as dirty battery contacts.

It happens both when charging and when sitting unplugged. I even tried swapping the battery for a new one and the contacts and also clean

Well, it was an idea. I did the same thing, buying a new OEM battery and hoping it would help. It didn't. But then again, mine often reboots at night (it woke me up at 4 am this morning), so I knew it was unlikely to be a battery issue in my case.

Yeah thanks for the idea but it seems like I'm running out of things to try

I feel the same. The only thing left would be to wipe out the phone and try it with nothing but stock, non-upgrades, apps. But I use the phone for work, and it can go more than a week between reboots (or less than a day), so that isn't practical.

I might just end up mailing my phone into Samsung to be repaired but now that I have it rooted is there any special steps that need to be done to unroot it? I was just going to do a factory reset and let AT&T android 5.0 do it's update if that will kill the root. I'm not worried about warranty since it is no long under warranty.

Maybe use logcat and letting it run and wait for a reboot to happen so you can see what is going on. However the logs could get big and it might not capture what happens right before it reboots.

At least once a week I go to use my phone and it will not turn on? I have to hit the power and volume down to reboot the phone. It's getting worse and worse does anyone know why this is happening. I tried to search I didn't see anything. I am on Att and stock.

I am sure you tried factory reset already? I had a few in phones in the past do that. Usually was a bad battery. When did it all start? How old is phone? Any apps you install and it started doing this?
Leaning more towards you will need to ship in for a warranty with Samsung.

This is my 2nd phone the first one got screwed up with a update. I have had this one for about 4 months and it just started doing it about a month ago. Now it has done it 3 times this week. Once just now and it happens on the charger and off the charger. It has made me late waking up twice. I haven't done a phone restore yet and I haven't installed any new apps.

Sorry didn't read right tired ha. Black screen usually sign of bad screen. Got mixed up and thought it was restarting on it's on. If there was no apps that caused it. You didn't mess with any settings? Said your stock.
If none of the solutions others suggest soon don`t work. I'd go for a factory reset last resort. Worst case you will have to ship again to Samsung sadly

That's concerning. I take it most people with same situation as yours, shipped into sammy? Sucks you gotta go through this bs again maybe.

Just as suggestion, but if you use AOD try turning it off and and see if this fixes the problem.
I had this problem with Ironman ROM and turning off AOD fixed the problem.

Hi,
If you can't reboot your device to fix black screen problem, you can try FoneLab broken android phone data extraction to fix it.
Download and install the program on your computer, and then connect device to computer.
Then you can scan, select and recover data with a few clicks.

Random reboots

I've been getting occasional reboots every couple of days. I wasn't too bother by that, but since I installed the latest security update 2 days ago, my phone has been rebooting constantly. I think today I've had it happened close to 10 times.
I've cleared the device cache which didn't help.
Will try doing a hard reset soon.
Anyone else have had this issue and may be able to point out some options to try?
I'm wondering if this was update related or could it actually be hardware?

I would guess software - it's painful, but back up what you have - and write down all the apps you have. Then uninstall them one every other day, in order of least important apps to you. When the problem goes away, you have found the app causing the issue. If not and you run out of apps, then do a hard reset. Don't reinstall everything at once. Start installing apps, only a couple every other day or so. If the problem comes back then you know which apps...
