Random Root Problem

So i bought my incredible the second day they were released, and rooted it when unrevoked came out with their first one-click root program (so needless to say im not exactly a "new" root user). i've ran a couple roms, and lately have run stock leaks w/ added .zips for a little customization (about the past three months or so). i've been on the latest leak for like a month ish (i think its the latest one) possibly little bit longer than that. i never had a random reboot or even really any lag up, which was really amazing. then, i tried to install a custom flat black notifications bar, and i installed the update zip through recovery but it didnt do anything.
about two weeks later, i installed that new status bar power menu thing, and started to get the occasional random reboot and bog up. no really enough to really be a problem, but tonight right before bed my phone started boot looping after a random reboot (it would boot for a min or two then reboot after a lockup). so i pulled the battery and powered back on. then it loaded to the lockscreen, but every single app that should have started at startup began to repeatedly force close, so i couldnt use the phone. i tried three times but it happened every time. im nandroiding now, im sure that'll fix the problem, but any ideas what caused this? thanks!

just happened again on ruby 2.0.0, but this time all of the apps force closed AND the "click android to start" setup screen came up. I got a random reboot (which i rarely to never have), pulled battery and powered back up, it loaded to lockscreen, then it went into a soft reboot and froze at the looping bootscreen, then once i pulled battery again and powered up, i got the crashes. any idea what it is? this time, it did happen like 15 min after i had dropped my phone from about 2 feet off the ground, i guess that could be it? idk

For what it's worth, I was running 2.3 and it wouldn't mount internal or SD. This happened even after installing other ROM's. I downloaded the latest RUU, unrooted, and started from scratch.
I reformatted the SD card too. I re-rooted, and restored my SD backup. I re-downloaded the ROM I wanted, and installed it. It fixed the weird issues I was having. You may want to consider starting over from scratch.

Random Reboots GSM GN 4.1.1 All Stock

Hi, I have a completely stock GSM GN on 4.1.1 and just since two days ago I have been getting random reboots. Only reason I can even tell is because I have my phone encrypted (lost phone and my data is in a strangers hands? No thanks) so every time it happens it sits at the prompt for me to input the password.
I initially tried clearing the dalvik-cache and that didn't work. So, I did a complete wipe and reflashed the stock images via the GN Toolkit. That also didn't work. Finally, I went through and uninstalled all apps that were installed or updated within the last week of August and it still didn't work.
I am at wits end here. I've owned my GNexus since the beginning of July and never had a problem like this. Any suggestions would be recommended.
EDIT:
I have also noticed that while I am using the device the screen sometimes flickers black for a second and then comes back on. Its not like the CRT Off animation you get when you hit the power button, just simply the screen goes black and then a second later comes back

Just bumping because I changed the issue from a hot restart to a proper reboot since I just got it doing a full at "Google" image reboot. Once it did just do a "Nexus Logo" reboot though.

[Q] Spontaneous reboots on the ZL?

Has anyone experienced any spontaneous reboots on their ZL yet?
Mine has done it twice, both times while doing things related to Google apps or accounts. The first time my phone rebooted, I was actually adding my Google account after a reset to fix the notification LED issue. When I unchecked the option to backup and restore my Google account, my phone blinked the xperia logo, then rebooted (Sony logo, xperia logo, boot animation then done). It was a very quick reboot.
The next time, I was installing apps from the Play Store. A bunch of apps were queued up, downloading and installing over Wi-Fi. I hit the home button, then was about to open up a folder to check my Gmail app settings when again, the phone blinked the xperia logo and proceeded to reboot. When it was done, it continued to install my apps as queued from the Play Store, as if nothing happened. It hasn't done it since (of course, this was only a few hours ago).
My phone is not rooted & I have not messed with the bootloader unlocking or anything. It's 100% stock while I'm evaluating it against my SGS3 for a potential permanent switch. I've got the US C6506 model (black, on AT&T -- LTE is working fine).
I really, really like this phone so far, and I'm just hoping that these two reboots were a random oddity, not to be repeated.
Interestingly, I actually fully set up the phone yesterday evening, but when I discovered I had the notification issue, I reset it this morning and re-did all of it. The phone did NOT reboot at all yesterday in the 4 or 5 hours I spent playing with it, either. It sat in standby overnight without incident as well -- all prior to the reset today & the 2 subsequent reboots.
I guess from here it'll be a waiting game to see if it does it again, but in the meantime, I was curious if anyone else had seen anything like this with their ZL.

Yup, seen it twice myself. First time, I noticed that it had rebooted when I couldn't find any previously running apps. The second time I was in the Settings screen when it randomly rebooted. I was just about to click the Display setting when this happened.
I'm just running the stock ROM on the C6506 model. I'm keeping an eye out on it and will see if there is a pattern.

Thanks ... in some ways it's good to know, and in others, it worries me. I hope it isn't a pattern, though. Thus far, I've used the phone since the two reboots without incident (music playing, bluetooth connections, and phone calls).
EDIT: A third reboot. This time I had just updated a few apps in the Play Store, returned to my home screen and was about to turn my Wi-Fi off when it rebooted. One common thread thus far is that my Wi-Fi has been on each time. I have no idea if that's related or not, though.

I have been using mine for 1 week and have not had any reboots. I am using the hspa version (c6502) and I am a heavy user

Seems to me that the random reboots are isolated to 6506 models. I haven't had one single reboot in the past week I have been extensively using mine (6502). However, while I was on CM10, my phone hung and rebooted like hell.

Yeah I'm c6502 aswell no random reboots.

No reboots on C6502
Same here, have been using my ZL (C6502) for the past 22 days without a single reboot or freeze. Heavy usage for last week or so (wifi on all the time). I too think this and the low call volume issue might be specific to C6506 (LTE) version.

6502 here as well, no reboots so far and I'm rooted. Been about 2 weeks.

I'm starting to think this issue is unique to me and/or my phone -- at least my specific case. Actually, I'm glad for that, because I love this phone.
I realized I may in fact have memory card corruption. I'm going to explore that further, because I had some serious issues with my SGS3 corrupting microSD cards. I thought it hadn't done it on my current card, but I have discovered some corrupted sound files on it, so I think I'm going to do a format of my microSD and see what happens.
Thanks for all the input, folks!

I had some reboots in past one week
using since March 10th
today itself had 2-3 reboots
one more thing is had blank screen during a phone call also
we need Roms for this device I never understood
why there is so much delay in release of custom Roms

Once,
but not sure it was rebooting. Cuz the screen went blank. Then i had to press a tiny yellow button that says off near the sim slot. Then it came back to life. Plus my wake up button is kinda hard to press. Do you guys hv that problem?

I wouldn't call that a reboot, at least not in the sense that I was seeing them. That's more like a freeze that would require a battery pull on a phone with a removable battery (I used to have this all the time on the Samsung Captivate).
My ZL was rebooting fully right in front of me (screen goes black, then the xperia logo, followed by the full normal boot sequence, just very rapid -- the boot animation is shorter than a cold boot).
Note -- I have not actually fixed my memory card yet, and I have not seen any more reboots. I'm nearly a full day on my current battery charge, too.

I have the C6506 also, and I get numerous random reboots also. I did get few logcats, but I have not seen any revelant info that causes the random reboots. I replaced my micro-sim, thinking it may caused modem panic reboots, but that wasn't root of the problem. However, I did notice that the reboots occurred less without micro SD card, but I haven't completely made that conclusion yet (I want to listent to my music!).

I also have a 6506 and have been experiencing some kind of reboot. Not a full reboot that the OP has been talking about, but one where my screen just turns off. At first I thought better battery stats was just having issues as my stats would end up all out of whack for no reason. Then today the screen shut off while in use. I only had to push the power button to get back to my lock screen. But again my stays were all out of whack. I'll have to pull the log later but I hope this is is just a software issue.

Interesting. I've replaced all my corrupted files on my microSD card as of now, and so far, aside from that first day, I have not had a single reboot of the kind I saw before. Actually, no reboots at all, and my current uptime shows it (111 hours).
What happened to me was I had had a bad microSD card in my SGS3 -- files would become corrupted with time on it. I finally replaced it with a new one, but apparently when I copied my data back to it, I inadvertently copied a few of the corrupted audio files (notification sounds, actually) but never noticed it. I realized this when I was resetting my notification sound for text messages and heard the signs of corruption in the file, and so I began to think my phone had been responsible for the corruption. I know now that that can't be true -- otherwise I'd have some corrupt photos as well, and I don't. Only a few select sound files were bad, and because I keep regular backups of the contents of my microSD cards, I just copied the wrong ones (d'oh!).
Of course, I've had random reboots on android devices before (Asus TF101), so I'm quite wary of them -- if I see anything further, I'll post about it.

I looked at the log and saw nothing conclusive that would be making my screen turn off. I also checked my up time and it hasn't reset, so I know it's not a true reboot. When I put my SD card in I just wiped it from the phone. The only thing I put back was music files. Thinking about that now it wasn't the clean start I usually give my phones. So I just wiped the card again and we will see today if anything happens

C6503 here and I've been getting a couple reboots a day since I bought it. 2 days ago I used PC Companion to solve another issue (random loss of network signal) by reinstalling the phone software and that seems to have fixed it. Unfortunately the random reboots are still present.
I don't use any SD card at the moment.

I've now been using my ZL for a month or so, and since that first day when I made this post, no spontaneous reboots at all. I have no idea how or why, they just stopped on their own.

[Q] 5.1.1 Random reboots ?

Anyone else experiencing an excessive amount of reboots? For as long as I've had my N4, my phone has never restarted by itself. But after updating to 5.1.1, my phone restarts at least 5-6 times a day on any app (snapchat, facebook, camera etc). Should have been a hint to backup my phone because now my phone is on a loop and wont boot up after the AT&T animation. Last resort is obviously a Factory reset. Any help would be appreciated!
EDIT: Wiping my cache partition did not fix the issue.
EDIT: Plugging the phone in the charger while rebooting somehow fixed it. Hope that helps someone having the same issues.

Not me.

My device has never rebooted itself since I owned it (bought on 10/30/14). Yesterday, I tapped the camera icon to use the camera and it rebooted. Took forever to boot up because I'm encrypted. Once booted, I again tried to enter the camera and again, rebooted. Now at this point, it will not stop rebooting. It was on a loop that seemed like every 15-20 seconds it would reboot itself and I'd see the Samsung GN4 splash screen. I pulled the battery to stop this since everything else was unresponsive. I restarted the device in recovery mode and cleared system cache. Seemed to work at the time. All was well for a few hours with light usage until I tried to use the Genius Scan+ app. As soon as I tapped the camera button within the app, the device rebooted. Once back up and running, I deleted an app that I sideloaded the day before called Parchi (it's a Microsoft Garage project app not available in the US Play Store). I figured it might have something to do with it since it's the only app I've installed in days. The app seemed to work for the first 24 hours however, I deleted it anyway just to see if that was causing the issue. So far, no further issues with rebooting and my battery life has been great as well. Prior to deleting this app, my battery went from 100% to 35% in like 3 hours with very light usage and maybe 20 minutes of OST.
Back to the issue at hand though, I've had 5.1.1 on my device since day one when AT&T pushed it and no issues with rebooting until yesterday.

Everything is crashing

My note 4 randomly freezes and goes to black. It also randomly restarts, gets stuck, and then restarts again. It's very annoying, if I want to check something, I hit the home button and the phone is frozen on the lock screen. Random apps are also crashing but instead if just closing the app my phone's screen just shuts off and I can't get into the phone for at least a minute. I don't know what the problem is and I really don't want to factory reset my phone.

I would pull the battery and take out the SD card (if you have one) and sim card and boot it up and see if that helps.

If u r using de-bloatware app then try restoring all the apps.

Factory reset, don't install anything and see if it continues. Then start installing a couple of apps till it happens again, try to identify the offending
App.

Same here.. Just started happening 2 weeks ago.. I have yet to find the offending app. ****ing ATT and their ****ty note 4 ughhhh

Happening to me too. Even after factory reset, and in Safe mode. I think it is from the June 16, update. I plan on taking it in to the att store and having them flash the new update to the phone. Thinking maybe my over the air update got screwed up somehow.

I put mine on ultimate power saving mode at night to keep it from dying since I forgot my charger. When I woke up, I tried to turn off ultimate power saving mode, but the option was gone. I rebooted and it got stuck at the att boot logo. I took it to the att store and they said I'd have to file a claim on insurance and that they can't fix it.
I cane home and connected it to adb to see if I could back up my files. Without sending a command to it, it wiped itself and factory reset. I lost everything, but since then I have had no issues.

Mine started doing this a couple of weeks ago. Factory reset twice, sd card out. Still doing it. Had to go back to note 3. With sd card and sim card out it seems to work ok on WiFi only.. No stuttering or force closes since?

Mine was doing the same thing. Turns out the battery was taking a crap. New battery and no more issues. For myself at least.

Mine is unusable. It boots into download mode half the time after factory reset. When I get it to boot up it only lasts for 15 minutes then resets again and gets stuck

Try what I did accidently. Connect to your pc. Boot into recovery lode and see if you can connect with adb. Then connect to with adb sideload and let it sit there. Maybe send a few commands and see if it will do like mine. It might get it to unhang. You might lose everything if it restores, but it might do like mine.

Mine mostly ok, albeit chained to at&t FIRMWARE, but I do get an odd eeror: when in a call the phone will make a a keypad tone,as though I'm leaning on the keypad [not], often mid-Bluetooth handsfree calls. It last 2-4 seconds, long enough to interrupt the flow of a call. anyone ?

I have had tons of apps update as of late. I too am experiencing lag, lock ups, black screen. I thought I was alone.

Had a friend's Note 4 do the same only he was on Sprints network. He was not rooted and on MM. I tried a factory reset and it helped for an hour or two then it went back to random rebooting or apps freezing. I tried flashing factory software through ODIN. It was good for an hour then went back to random reboots and apps freezing. I tried another ODIN flash without restoring any of his apps and the same thing happened. I tried changing the battery and that wasn't it, I removed the SD card and that wasn't it either.
He had to take it to Sprint and they ended up just giving him an S7.

I started having this problem just after the update. I tried to switch the battery out and tried to take SD card out. I factory reset it about 3 times now. Nothing has solved it.
I took it into AT&T, and even though I'm not under warranty anymore (had phone for almost 2 years now), they worked with me and ended up giving me a new s7.
I suggest you go talk to AT&T because this is a problem with all AT&T Note 4's. Tell them you want it fixed and talk to the managers and get them to contact the corporate help desk. Don't leave without them fixing it. You paid $900 for this phone.

Gave you a new S7? Or swapped it out on a next contract?

I did not pay a dime. But you have to show them that it freezes and crashes even after they factory reset it

Just left an [email protected] store. He looked at me like I had 3 heads. He had never heard of such. Will call corporate and work my way down.
I did hold a S7 edge.... it was a thing of beauty and speed. No ir though... it's why I like note 4

Works without sim
I've had the exact same issues, (Galaxy Note 4 on AT&T). Tried factory reset, wiping cache, re-flashing with odin, removing SD card, removing apps, multiple batteries, etc.... the only thing that has worked so far is removing the SIM card. It runs flawless without it. Currently using my S3 for calls and text and use the note 4 like a giant iPod touch on wifi only. Hoping this is a software issue AT&T will correct but knowing them..... best bet is probably to wait until August and get the new Note 7.

Why not try the MM update that is out right now, it´s not an OTA but by just renaiming the file to update.zip, putting it in your ds card and applying it through recovery you will have a practically new phone, it´s worth the try.
I´m ruuning it and it´s been great so far, no bugs, no errors.
