Why does my S4 keep rebooting? [Log Inc]

EDIT: Here's a verbose log that was being recorded before the device rebooted as explained below. It happened 2 seconds after I locked the screen with the lock key...
http://www.fast-files.com/getfile.aspx?file=74248
I know it's a big file, and it's long but it does open in regular Notepad, just wait 40 seconds. Hopefully you can find the cause at the bottom of the log. I can't make sense of it.
---------------------------------------------------------------------------------------------------------------
Hey guys, any idea how to find out why my S4 seems to be rebooting every few hours, mostly after being woken up?
Some tech info:
Baseband: I9505XXUGNE5
Stock Kernel
SE For Android: Enforcing
Build Number: KOT49H.I9505XXUGNE5
Phone is rooted & Xposed installed
Quick bit of info:
It seems to happen 90% of the time when the screen goes off. By this I mean, the screen can go off no problem and then I can turn it back on without an issue. However if the phone does reboot, it seems to be when the phone is woken up after being locked/asleep. However it does happen sometimes whilst I am using the phone. Though very rarely.
It's also important to note that the phone does a 'fast reboot', not a regular one. Like it skips the 'Samsung Galaxy S4' screen and just goes straight to the spinning logo. It does reboot very fast, but it is really annoying.
However I don't have to put my SIM PIn in again, it just asks for my phone PIN and then starts to load apps as normally.
Is there some sort of App I can install that will log all errors right up to the point where it crashes. Then I could view the log and work out what caused the crash? I have the Donate of aLogcat but it doesn't seem to allow me to do this...
Any ideas guys? Any info would be absolutely awesome.

I really don't mean to bump guys but I've flashed 3 times now and still get reboots...
Could I need to flash a new boatloader or something?

The download is to slow. Just post your log in pastebin and post the link here.
What I would do in your case is to fully wipe (also wipe your sd card) and return to a clean rom. Don't install any apps, dont restore backups and see if the problem persists.
If even with a fress install you have to issues, then it's a hardware issue.

Hi, thanks for the reply. It seems that it could be a bad official release actually:

I added my 2 cents at the end here. Hopefully freezing everything KNOX related (as KNOX was updated in this version) will fix the issue.
I'll report back and say if it does anything.
Once again thanks a lot for the reply. Fingers crossed this works and that it isn't a hardware issue.

I would suggest performing a factory reset before freezing the Knox stuff. That way you have a clean start.

I'm also experiencing the same issue ( random reboots) but let's make one thing clear; this is happening ONLY after rooting. No reboots if you do NOT root, all works fine. Another thing I would like to establish when you guys say delete Knox apps, do you aside from doing search in Titanium Backup and deleting all apps entries, also do a search in the root folder with Root Explorer and delete every Knox entry? Because in my experience if you do that, the phone will not boot beyond the Samsung logo.
What i also experience is a freeze when the phone asleep/idle for a while or after a battery recharge the lock screen will open but the home screen is frozen you have to turn the screen off/on for the home screen to react. God knows how many times I have reflashed this rom, at least a dozen times. One thing is sure, its absolutely perfect when it's not rooted, no problem at all. Here is what I install after rooting
:
SdFix
AdAway
Root Explorer
Rom Manager
Titanium Backup
* I also experimented with TWRP, CWM, PhilzTouch (all latest versions) and rooted with Cf-Auto root and Via update SuperSU v1.97, v1.99.r2, v1.99r3.
So there you go, my analysis is that without root all is fine. But I and I think all of here want root, so I hope someone gets to the bottom of this. I already sent the venerable Chainfire my experince with this rom. Fingers crossed.

It's doubtfull that rooting has anything to do with it. You are using the Chainfire root and from what I remember is that it doesn't change anything in the kernel that would result in those errors you descripe. Did you try rooting and not installing those apps? Also did you try other roms?
My guess is is that it's SdFix that is causing the lags.

Chainfire asked in another post people who are experiencing these reboots to list their installed root apps which I sent to him.
http://forum.xda-developers.com/showthread.php?t=1538053&highlight=random+reboot&page=551
Maybe it is SdFix. I will check that out but, I would like to know if others who are experiencing reboots here have SdFix installed or maybe to list their installed root apps (like Chainfire suggested) so we can compare notes as to who is and who is not experiencing random reboots.

[ Help ] Blue screen Error , Samsung grand 2 (4.4.2)

Hello Friend Recently I update my grand 2 to official android 4.4.2 Firmware , And The problem is that Sometimes It restarts automatically after showing BLUE SCREEN . Can anyone facing this problem ...?? Can anyone please Help me to Solve this Problem ..???

hey, let me help you.
what was the situation when this wierd thing happened?
eg. were you playing game?
or surfing internet. or any other..
was your phone rooted?
did you installed xposed framework?
(i've seen most blue screens in Xposed)
if you have installed xposed framework then either remove recently installed modules or completely remove xopsed framework.
and if your phone hasnt been rooted, and you are facing blue screen problems, i think you havent factory reseted your phone, so perform factory reset and wipe cache frome recovery..
hope this helps.

Hey Vrushabh thanls a lot for your time , This happens only sometimes like once in a week.
I had rooted my phone earlier but after this crash i formally uprooted my phone and from last 4 days it has no problem .... THANKS AGAIN BRO.
Now my question is that , what was the reason behind this type of blue screen error...?

I have the same problem with my Grand 2. It automatically got an official update 4.4.2 and since then whenever I use it for a while specially on facebook, the cell gets restarted after giving a blue screen. I have made the factory data reset and since then its a bit improved but the problem still not gone altogether. Please if you can give any solution?

Grand 2 Duos Bluescreen
Hi all,
I also encountered the blue screen and restart error. This happens randomly like using Whatsapp, 9gag or Facebook. It also restarts for no reason at all.
The phone is not rooted by the way. I tried running it on safe mode and nothing happened. After normally booting it, it crashed twice. First with a blue screen and the second was an automatic restart.
Thanks

I think this happens because some times Apps are trying to write something on prohibited areas of system , and that's why OS restarts Itself to prevent data looses .

Are the people having this problem on SM-7102 and perhaps the phone bought/CSC from India?

Terrible mistake

Hi folks!
I did a terrible mistake on my rooted SM-G901F yesterday, maybe I was drunk or something!..
I noticed that the settings process was draining a lot of battery, so I decided to do a backup with TiBackup, and then uninstall the settings.apk to see if it makes any changes. There was the mistake...
The changes are that the phone boots properly and seems to work well, but it's not the case anymore with the touchscreen wich doesn't work at all, so I'm totally unable to use it.
The only thing I managed to do for now is to retrieve the settings.apk backup but I need to force the installation by USB I presume.
Any clues? It may be quite simple but it's out of my knowledge, your help would be greatly appreciated.

After some research it seems possible to install an APK in a .tar container with ODIN, but I'm unsure about that.
Or the other solution is to re flash the 5.0.2 official ROM, am'I gonna loose all data if I do it?

Please help me in fixing rotation problem in samung s5 (g900w8)

I have read too many posts and solutions but nothing have solved my s5 problem, which is not rotating.
I lost rotation after flashing a new rom on my s5 (actually suddenly after two weeks of installing the new rom).
I have to mention that if I removed the battery for more than a min, "sometimes" it works again but not for long time, and when the screen shut down it stops from rotating.
I downloaded cyanogenmod roms but also didn't fix it.
I tried to reset my phone using kies, and it worked back for one day, then stopped.
I also tried the method of replacing libgnustl_shared.so file in system/lib and changing permission (as described in this thread http://forum.xda-developers.com/showthread.php?t=2644293), but it didn't work with me.
Please, I am so desperate to fix this problem. Anybody think it is a hardware problem?, if yes, why it works after restart with battery removal sometimes?
I am eager to solve this problem, and thanks for everyone who wants to help

Help with Magisk?

I don't know what is wrong with my phone, I've searched the web for answers only to find nothing, I've asked in other threads and got no answers, I need help. So basically my issue is Magisk on my Mi A1 this issue happens with both 16.0 and 16.4, on the stock Mi A1 rom occasionally when I reboot my baseband and IMEI is unknown and when I reboot it fixes it's self temporarily I know this is not an issue with EFS partition as when I uninstall Magisk everything is fine and on custom ROMs I don't get this issue but a whole other different one. Also on the stock ROM Magisk causes bootloops sometimes which is fixed by rebooting.
When I use Magisk on a custom ROM I get a different issue, whenever I use Magisk to do anything on my device it causes an issue where sometimes when I power off my device it shows the boot animation before powering off.
I'm really sick and tired of these issues and any help would be really appreciated.

I have the same issue with the no imei/baseband in stockrom with magisk
created a thread like you asking for a solution, got not answers, not sure if is because not enough people mod this device or is something else
I for once as soon as I got it, unlocked bootloader and installed magisk and xposed, everything else is stock
issue still persist, you need to reboot again for imei/baseband to comeback

I'm currently running a custom rom and I've discovered that the issue I'm facing there has nothing to do with Magisk, its when I open an app like Titanium backup, even unrooted the app want root permissions causes the boot animation at power off, anyway I'll make a logcat when I get chance.
