[Q] nc randomly reboots

Hey guys, my nookcolor has been randomly rebooting since i rooted it. Never while i was using it, i just sometimes hear the bootup sound, and look to find that my book is now on.
Im just concerned this will affect my battery, and i also don't want it rebooting while im using it.

I noticed it doing this one time, but right after i powered it off. In use, it has never rebooted on me (yet)..
This is why we so desperately need a custom ROM. Remove the B&N bloat, and start with a clean 2.2 (or even 2.3 now) base, and really open her up..

I still want to use the B&N stuff. Any rom that emits them, I will not be installing.

I think it likely that there are NC users in both camps-
Those who want the B&N stuff and those who don't.
I am one of those who don't; the Nook for Android software does better for reading ePub, imo and I am rarely near a B&N store.
Right now we have root and Market plus B&N and I would guess (could easily be wrong) that the first custom roms will be pure Android with no B&N.
We will probably end up with an option to set while flashing: retain B&N customizations or straight Android.
I base this guess on what I have seen in the other roms for various devices (mainly Droid) I have looked at.

Same here. If I want to read B&N books, I could still use their Android app on a custom ROM.
After switching to Cyanogen on my phone, it's been quite relaxing to not have to worry about provider updates bricking the thing or otherwise screwing up the rooted customizations (or just randomly resetting the thing back to factory defaults because I started up one of their apps and it got confused). Not to mention that the CM team does a far better job supporting the device than the manufacturer and my service provider does.
And yes, like other Android devices, there will probably be ROMs in both categories: completely built from scratch with no B&N portions at all, and improvements on the B&N system to add more functionality.

Fair enough for those that are interested in the reader portions - i have to admit, i bought this as a tablet, with literally 0% in it as an e-reader; i already have a Sony 505 for that. I may use it on occasion, but only as an afterthought.
However, this topic is really drifting - perhaps we should just bring it back to the rebooting issue?

Yeah, I installed the Uptime Widget on my NC today and picked it up a few ago and its uptime was 1:30; max 15h (from before it rebooted 90 minutes ago). I'll keep running it.
What we need to do is get a logcat when it happens.. So maybe overnight I'll leave it running or something. It just rebooted on me and I was semi-watching it, didn't even notice but Uptime Widget was reset to 7m up, 15:30 max..
I have started up a logcat and I'm going to leave it running while I get ready to go out for the day.. Although I just installed and fiddled with Google Earth, which failed badly, so I wonder if it caused some problem. Also saw it happen after playing with Google Maps, so I wonder about Location stuff maybe doing it.. Dunno. I just launched Maps a few ago and it's been up since. Hopefully a logcat will capture some info.
I have noticed that I've seen some crashes that don't show the Crash dialog.... TweetDeck is particularly bad about crashing viewing some Facebook posts, and in this case it just goes black for half a second then back to the list of posts. A logcat shows it crashed. But I don't know the two are related (not having the crash dialog stuff and the reboots that is).

I had it reboot on me twice last night, one time I didn't know about it until I picked it up later and noticed the uptime widget was down to some 30 minutes, and another time right before bed I hit the power button and about 10s later I saw the boot up text and a reboot happen.
Still haven't caught it on logcat.

My doesn't reboot spontaneously, but it does "lock up" and won't turn on with the power button from standby occasionally. If I remember to use the Nook Button to wake from standby, I don't seem to have this issue. If I use the power button, and it won't wake, I need to hold it down for ~15 seconds and it reboots.
AFIAK, it has done this since I purchased it (I rooted after about 1 hour with the NC in my hands).

Mine has never reboot WHILE I'm using it, it's sneaky about it. But I suppose I'd much prefer it reboot while I'm not using it than while I'm using it; I have yet to have it do a full reboot while using it.
Trying to set up a Delicious account.. yeah, that rebooted the Java VM. But only time I've made it reboot at all.
Hahah, damnit, it just rebooted after it went to sleep. I seriously think it has something to do with going to sleep. I've been sleeping it and waking it repeatedly on adb logcat and it won't crash. Figures.

I had this same issue a while ago. I don't have the logcat from it, but from what I could tell is was some sort of error coming from the system dimming the brightness before turning the screen off. I had Extended Controls installed and was using the widget to adjust my brightness. Whenever the screen would dim before turning off I would get a reboot. I have since uninstalled it and have had no issues with reboots. I'm not sure if this is the issue youre facing but thats my story.

Actually not using any of those on mine.. I have Beautiful Widgets in ADW and Beautiful Widgets + Note Widget in WidgetLocker.. Not adjusting the backlight at all either, in fact I don't think I have at all since getting it now that I think about it.

I have the same issue: rooted Nook Color reboots occasionally and it does seem to do it whenever I put it to sleep or it goes to sleep by itself (when the screen dims). It hasn't rebooted while in use, but it does reboot occasionally when left alone. Have no idea why.
From apps that control dimming I have Advanced Task Killer installed besides the stock app that controls dimming... Could it be the issue? I will uninstall Advanced Task Killer and see if that help.
Otherwise I love my rooted NC. It's fast, beautiful and works great as an E-reader and an Android tablet.
to summarize: Do you think it's the hardware issue or software. I've heard of people who have non-rooted (stock) Nook Color having the same rebooting problem, but apparently it doesn't have to do with rooting. Do you think it will adversely affect the Nook?
If anyone finds a solution please post here. It would be tremendously appreciated.
Thanks and have great holidays.

I suspect it's a software thing, as it doesn't randomly reboot in use, it ONLY seems to happen going into standby, and I have YET to make it happen connected USB for adb.
You know actually, I think alogcat can log automatically now, maybe I should try that.. but it'd have to run for a day or so, as I only see this happen like twice a day at most.

Do you have setcpu installed? I was getting random reboots when I had it on conservative. Switched to ondemand for all profiles, and no more reboots!

I myself had not played with SetCPU at all. So had you in the past and set it to conservative, and switched it back, or you switched it from its defaults? Reminds me, per my observation that it never has rebooted while on AC or USB, was there a default profile when plugged in that it's set to ondemand vs conservative? This could start making some weird kind of sense. I'll try it, but using something called CPU Tuner since it's free..
EDIT: I looked on USB and on Battery, both times was conservative, so looks like that's the default... Does the Nook have an automatic switching utility like cpuspeed in it? Hmm.. /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor is the file if anyone else wants to look.
BTW, has anyone on 1.0.1 auto-nooted etc not seen these random sneaky ninja power-off reboots? I swear mine waits until I'm not looking and reboots. I've only SEEN it do it once or twice, but in the last 5 or so days it's rebooted at least 10 times while powered off. Again NEVER while I'm using it, so I'm at least thankful for that. If it were rebooting while using it that would not be acceptable.
I have the Uptime Widget, kinda wished I had an uptime graph to see if there is a pattern.. I'm about 99% sure it never happens when plugged in AC or USB.
EDIT2: IT IS CLEARLY MOCKING ME. It just rebooted after I peeked at the governor files and let it idle to sleep.

I have the same random reboot problem since I upgraded to 1.0.1 and used auto-nooter. I only see it when it goes to sleep...or so I thought. This morning I heard it reboot and i hadn't touched it since last night. FYI, it was not plugged in when it happened. Thankfully it never reboots while in use.
Oh...ad i havent used any CPU clocking tools. Also...never saw this on 1.0. So weird but I am sure someone smarter than I will figure it out.
UPDATE- Just got out of the shower and while getting dresses...heard the Book reboot twice within a minute or two.
Wondering if its an app that is causing a fatal crash when it tries to update.

I haven't had a random reboot in 3.5 hours and i have used the Nook on and off. I did remove my email account from the Google email app (not gmail) and its been good for awhile now. I will update if this changes but I am feeling confident this fixed the random reboot.

I've had one unexpected reboot today that I know of, I think this has helped, although I keep finding my Wifi turned off, even though this program I installed is only set to turn it off when the battery is extremely low. So I changed that profile and it hasn't turned itself off since, so seems to me maybe the battery reporting is a little wonky sometimes.
I've been watching, and I'll keep an eye out, but I think wvcachi is onto something.
BTW, the Nook has been primarily idle for the last 5 hours, just popped it on a few times to read an email, check on something, or see if it reboots so I haven't used it a bunch but it's lost a whopping 2% battery in that time. I also disabled the Phone stuff too, per this thread:
http://forum.xda-developers.com/showthread.php?t=883908

I am at 6.5 hours now....no rebooting so far.

Flashing Green Screens while screens load

So this was happening before but I factory reset my phone and now after about a week and a half it's happening again;
everytime i either go back to the previous screen, or while i'm on a loading screen (noticed it a lot with Netflix) but i get these green pixely squares that flash on my screen... this a known issue with the version? or should i take my phone back?
I'm not really sure how to better describe it...

Have yet to experience that, had my unit for over 2 weeks.
Take it back.

I have the same problem with mine had it since it came out?

I've had the same issue. Started happening within 2 weeks, but more recently it hasn't happened much. A battery pull always fixed it for me. I'm experiencing random reboots when the phone hasn't been touched for ten minutes, this is more disconcerting to me

I haven't noticed it after a reboot for a couple days now...
But i do remember almost directly after it first happened (before i did the factory reset) my phone started doing the whole random reboots too. That's when i read the post about fixing the camera and not using the assistant backup/restore functionality when you activate the account...
I thought it had fixed all the issues but seems they're still there just, less sever...

Rebooting the phone (temporarily) fixes the issue for me
[sent from my droid]

I swear, after using the camera this happens. Until I reboot I get some kind of green checkerboard whenever the screen rotates or changes

Same here. Every time I use the camera and sleep the phone it will get hot and drain the battery. Waking the phone gives me green pixellated images and serious slowness. Battery pull after taking pictures is the only way to mitigate it...for now.

So this seems to be a common issue... has anyone been able to talk to motorola? is there an update coming out anytime soon to get it fixed? or is it just a hand full of bad phones?
smc, have you still not experienced any of these issues?
can you try seeing if it might happen after some of these scenarios listed in this thread? would be greatly appreciated!

[Q] Galaxy Note not waking up?

I can't put my finger on this issue I've been having with my Note.
Don't get me wrong, this device is a godsend!
The problem I've been having is that sometimes when I take my Note out of my pocket and try to press the unlock or menu button it doesn't show anything on the screen. I've read about people having issues with delay before it pops up, but it doesn't pop up even after 10 seconds or a minute, it feels like the device 'hangs' or doesn't want to wake up. The only way I can turn the phone on again is by pressing the unlock button for like 10 seconds and the phone reboots.
I thought it was a problem with Green Power, I thought it maybe had issues turning off the wifi or data when the screen was locked and that the service would cause the OS to crash or 'hang'. When I look at my battery history after the reboot it shows that I lost a significant amount of battery (5-15%, depending on how long it took for me to 'discover' the crash) and there's a 'jump' in the graph.
Things I've tried:
Stock rom - problem persists
Different kernels - tried all the kernels available in the market including stock, problem persists
Add a bit of paper between back-cover and battery (to make sure it doesn't lose contact)
Checked if there was dust between battery connections
Tried different sim card
Tried disabling wifi and data all day (mysteriously persists)
DIfferent governors (ondemand and interactive) (the phone reverts to default governor after the forced reboot, normal? i have my phone set to interactive on boot, but somehow it skips that after the forced reboot)
I've attached a picture of the battery graph. According to the stats there's a 25 minute gap where the phone was 'stuck' and you can see that the screen was on and active for that duration.
There are NO funny apps running in the background, this is is a clean install with some standard Samsung apps frozen.
tl;dr version: phone randomly won't wake up; battery loss after forced reboot;

I might have found the issue myself. Now when I come to think of it, I think it always occurs after I've been in my car for like a 30 min drive... Maybe the phone is having trouble switching networks? Anyone know what might be causing this?
Or better yet, how can I research this issue? Can I enable some logging somewhere to track this?

I had the note for about 10 days and today, about 1 hour ago it happened to me for the first time. I tried the home button to wake the screen but nothing, tried the power , nothing and holding the power but nothing happened. I had to pull the battery.

I had this problem in the beginning, but no more.
It's one of two things, in my case. Restoring apps (with data) from Titaium backup, or SetCPU or both. Do a factory reset, reinstall apps without data. If using setCPU, disable it for a while to see if it happens again. It's been over a week and the problem is gone.

I was using System Tuner instead of SetCPU to freeze apps and change governor, maybe I've just been using the wrong app? I deleted it just in case. Will see if the problem persists, thanks!
The nasty thing about it is that it seems to happen randomly (but it most likely doesn't) and is pretty rare (happens once every 3 days).
Still, I don't like the fact of not being available for X amount of time, even if it's 30 minutes.

I'm on stock room and unrooted. Like I said first time it's happened.

i've had the GNote since 4 days now , and yesterday same thing happened as the device was in my pocket and i couldnt wake it up at all , battery pull solved it.
im on stock , non rooted

I can't believe that we are the only ones with this issue. Anyone else? OR better yet, how did you resolve it?

Dont know if this is the same issue as the streak had, but with the streak if you kept it your pocket with the screen facing your body this would sometimes happen. Flipping it so that it that the screen doesnt face your body in your pocket solved this issue.

Thanks for your reply. I did some research, and apparently it had to do with static being built up in the screen from wearing it towards your body in your pocket.
This issue was that you couldn't swipe the lockscreen cause the touch screen wouldn't respond. The problem we are having is that the screen won't even turn on and that the system locks up.

Same issue here with my 2 days old Galaxy Note, that's how I found this forum. In my case it went from not waking up occasionally to every time WIFI was ON (I did some experimenting with settings to see which one could be the one causing the problem). But then...occasionally it would not wake up even with WIFI OFF: very annoying. And this is my first Android, so I didn't have any custom anything, pretty much same as out of the box when I got it The only solution was to reset the handset. And definitely has nothing to do with having it in my pocket as I don't carry it in my pocket. Rang Samsung, they told me it was faulty, I returned it. Now I'm concern the next one is going to have screen issues? As so many people complain in this forum? we'll see.

My issues have been resolved after flashing AbyssNote 1.4 and when I stopped using System Tuner. I've started using Voltage Control instead and now I'm not even having problem @ 100Mhz undervolted 50mV from stock.

Same problem with my wife's Gnote, totally stock, just a small handful of apps installed. Happened twice, about a week apart.
She does a lot of travelling, maybe you're right about that. But it happens after she gets home when it's still OK.

Had the same same issue twice in two days and had to do a battery pull, just did a master reset and re -installed the applications manually, so far so go.
YOu guys think its a hardware or a software issue?

Hmm.. Happened to me too about three times in the last two weeks. I am on stock rom but rooted, and running Green Power. Hopefully samsung will fix it in the next updates. Seems like a software bug to me. Maybe not enough juice when in deep sleep?

its the problem of your kernel. try Abyys 1.4 and use XDA Superpower to adjust the CPU-Frequency automatically

It's very well possible that the stock kernel has faulty settings for the CPU. Haven't had the problem again with AbyssNote 1.4 and Voltage Control (even with custom cpu frequencies)

at this point we're just guessing, there haven't been any official confirmations of the problem as far as i know.

[Q] random reboot/mms bug?

Hi there,
just wondering if anyone else are having issues of their phone randomly rebooting? does anyone know of a fix?
also, sending photos as an attachment does not work. in order to send a photo to anyone on your contact list.
found a work around by going through gallery and sending it directly from there.
if anyone know of a fix for either issues. the help would be greatly appreciated.
Thanks,

I've had several random reboots. Oddly enough, they usually occurred overnight when I wasn't using the phone. I would hear the vibration on my windowsill and saw it was rebooting. I did a factory reset yesterday and while in the midst of setting everything up on my phone, it rebooted again. I thought that maybe there was too much going on and it overloaded. But last night when I was out and not using my phone, it rebooted again. I'm gonna have to go to Verizon to swap the phone.

It keeps happening on mine, but almost always in the car while attached with BT. I'm wondering if BT has something to do with it, in my case.

Same thing
I am also experiencing the issue specifically at night. I have yet to actually have it interrupt me in anything but its still a concern. Just curious about whether for those of you who are experiencing it are using the Assist app or Android Assistant?

I only use the Assist app for when I'm in the car. It's not setup for night time. I exchanged my phone at Verizon today and so far so good. One of the employees tried telling me that the reboots could have been because I had Better Battery Stats installed on my phone and the battery saver apps can conflict with the OS. I blew his mind when I told him that BBS wasn't a battery saver app and simply lets people know about specific wakelocks. Seemed like no one there had any idea this phone even existed.
For the reboots, I guess tonight will be the big test.

It happened again to me this morning as soon as I got in the car and it connected to Bluetooth. Once it reboots, it's solid.

Please report back. I have gone 24 hours without a reboot with no changes to the device which is a first. If it doesn't have a Samsung or Apple logo no one seems to care anymore.

I can't get Assist to work at all. I typically listen to podcasts in the car and when texts come in I get a notification sound but I've never had one read to me. I disabled Assist to see if this was the cause of my Bluetooth reboots, and it's not.
With Assist disabled entirely, each time my phone pairs with Bluetooth it connects but the moment I start to play something it reboots. It's very consistent.

Just wanted to let everyone know that I haven't had any reboots with the new phone. I exchanged my old one for this one on Monday and so far everything's been good.

I have now had 3-4 random reboots that I have seen. I have also witnessed a complete lock up of the phone. I will be heading into Verizon today to exchange my phone.
Just wanted OP to know more people are having issues.

Random Reboots

Anyone else suffering random reboots? I have got my Note 8 N950F for a few days now and sadly have to notice that I see random reboots from time to time. Sometimes I saw the Samsung boot logo, sometimes i noticed it because I hat to enter my PIN after reboot. For now it seems to happen once or twice a day. Quite annoying.

Rogue app?
Sounds like something installed is not agreeing with your device. Usually thins can get tangled up when you do a restore from an old back up for example.
Did you have an older model note device that you restored form perhaps?
I'm using a T-Mobile variant ands no such issues.
As an aside, there is an option in the phone (you may already know this) that will restart the phone at a setting you setup.
Maybe also try clearing cache on your device?

Did you disable a lot of stuff with a package disabler?

A couple of mornings now I've woken and my phone asks for a password because it restarted overnight. I haven't experienced a crash or reboot yet, but something seems to be happening overnight.

No, nothing. Software was installed by transfer via Google account from Note4 with Lineage OS.

Do you have Substratum installed? I installed Swift Dark and noticed what I call mini reboot, phone would lock up for a second and just the carrier label came on and everything was fine again. Was using the S8 for my Substratum setting and I guess the Note 8 isn't compatible yet. Uninstalled most of the layers and haven't had a reboot since.

Ive seen people that posted having random reboots being that they transferred a backup to the new device.
There's something to be said in a fresh manual install into a new machine with new guts and firmware/builds....

My Note 8 just randomly rebooted itself this morning for the first time. I have had my phone since September 7th. After the reboot it has been fine but shortly before it rebooted it quit functioning altogether. I think I will go in and clear the cache when I get to work.

Its a system wide ad-blocking app that does not require root

My note 8 n950u1 has rebooted multiple times, but not in one day. It has restarted for the third time (ever) this morning. The first time was Gmail, second was Facebook, and this third time was Gmail again. My best guess is it might be a ram glitch because it seemed to happen when the app was trying to do a lot. Now, I have no idea if this is true, but it is my best guess. At first I thought it might be because of the snapdragon but seeing how others on an f varient with the exynos chips are rebooting too, that theory is shut down.

Could be apps like others pointed out. 2nd option the battery? But due to how new this phone is, I doubt that. In my past phones it was old bad batteries.

Not a single random reboot since day one, I got my note 8 on 22 Nov 2017, I dont use substratum or adhell, but I installed bk disabler and blocked all bixby, microsoft, google music, video, books, all carrier trash, almost all samsung stuff in "bloatware section", also disabled many services in a lot of apps, I am running naptime, greenify and hibernator, so far, all working fine

SM-N950F here same problem.

Mine ended up random rebooting four times from Sept 7 through about Feb 1. Then about two weeks ago, it completely froze, then decided the port was wet and wouldnt charge at all (port wasn't wet). tried a few things, then did a factory reset, where it actually rebooted probably 20-22 times (well, during the reboot process, the black screen with Samsung flashed probably 20 times).
Needless to say, I talked with Samsung and then TMobile. Got a replacement and it's been great since.
Can't believe it's now been over 5 months since I first got my Note 8. Even counting the replacement, I still LOVE this phone.

It seems Oreo Update has fixed this, at least for me. No unwanted reboots since a few days.

Thanks for the update, please keep us up to date even if you continue to have no problems under Oreo. BTW, I have the exact same problem (using N9500 dual SIM with Samsung processor as opposed to Qualcomm) as you but do not have Oreo available yet. I'm getting the restart message every few days and its always after the phone has been idle, usually overnight. Its asking for a PIN due to restart as I use face recognition. Also I transferred over data from a Note 3. Want to ask you, did you try to wipe the phone completely as a solution to the restart problem (before Oreo became available)?
Thanks so much in advance!

I am still waiting for oreo OTA, but after almost 5 months, I have not had a single random reboot or freezing, even though I have a bunch of stuff disabled
