[Galaxy Note 3 Q&A, Help & Troubleshooting] mancuk29:
Question did you have you'd sad card in another android device before your note three ? As well as the gmail issue I have found through trial and error the note 3 doesn't like any memory card which has been in another device (and has hidden android files on it) also ensure no apps install on your memory card .. I think we have been unlucky having the note 3 just as there is an issue with gmail plus I think samsung need to sort out the installing apps on a memory card or is it a querk of 4,3 android ??

Since wiping my memory card , disabling gmail , installing all my apps on my handset and not on the memory card I haven't had one boot cycle touch wood
[Galaxy Note 3 Q&A, Help & Troubleshooting] Nani:
I've stopped looking for the apps that were faulty because at some point, boot loop occured with and/or without some of them ... Like it was random ...

One thing for sure now is that all apps installing stuff on sd card ARE the source of the boot loop.

I've done one simple test : i put my sd card on my pc and moved all the content of the directory .android_secure to another one.

Them I put back my SD card on the phone => no more bootloop.

So i'am definitively convinced that the problem is not hardware but software,

It's like the phone has problem handling this directory or more precisely handling, during the boot, the access to SIM Card AND SD card at the same time...

At least there's a few apps installing data in this directory ... I moved them to phone memory and no more problem now !

While waiting for a Sammy update, for each new app i will install, i will have to verify if no data has been stored on SD Card ( XDA is one of them :P )
[Galaxy Note 3 Q&A, Help & Troubleshooting] captainhakan:
My Note 3 can boot without a bootloop with no sim and sdcard. I formatted my sdcard using Note 3 and didn't work out for me as well.

Exactly! How do we know if our devices are ok while waiting for a firmware update (even if that's the case!)

I don't think it's a sdcard related issue as few of us already tried to reformat to solve the issue with no success in the end.

I don't think a software related issue as most of us can boot with no sim and sdcard inserted.

I've been using a simcard which is not orginally a microsim but cut later to fit into microsd slot. I had no issues using it on my previous galaxy note 2 so i never suspected it might be the reason of this issue. But then i thought to myself about why my brother and father don't have any bootlooping issues on their Note3s and realised they both use simcards which are originally produced as microsims. Then i borrowed my brother's microsimcard just to see how it will process in my Note3 and i had the bootloop again! I still suspect that simcards which are not originally microsimcards out of the box could be the reason of the bootloops so can u guys who have bootloop issues infrom us if the simcard u use has been cut to fit into microsd slot or if the simcard is orginally supplied as microsimcard at first place ?
[Galaxy Note 3 Q&A, Help & Troubleshooting] danushenko:
My SIM is original micro sim. Megafon, Russia..And I have the bootloop issue
[Galaxy Note 3 Q&A, Help & Troubleshooting] Nani:
Just to be clear now with no apps using .android_secure folder, SIM and SD Card inserted I have no more bootloop.

That's why i think it's only a software issue.

One more thing : i had strange messages at first regarding insufficient internal space storage or external.

When working around the .android_secure folder, i see that from the phone this directory is protected and the only space available is the space used by the data inside !

---------- Post added at 06:17 PM ---------- Previous post was at 05:58 PM ----------

One other thing that can come handy.

During my firsts tests i was always using boot recovery (wipe cache and wipe data) and still sometimes even without the SD card the phone was still going in bootloop.

For my last test I used the Save and Reset menu.

And now as I said in my previous post the problem is handled.
[Galaxy Note 3 Q&A, Help & Troubleshooting] captainhakan:
I always tried to cşear apps through wipe cache / data via recory or the factory reset within the touchwiz before. After reading your post that you are %100 sure it is software related i tried to remove the apps automatically downloaded via play store at first setup then voila! it fixed the bootloop problem at last ! I haven't removed any of the google apps or updates tho just user apps so i'm %100 sure it's not google+ update or gmal update related. Before i started to clean the apps i checked out my freshly formated sdcard folders and there was simply nothing inside the android_secure folder in times i had bootloop problem. So it's not about android_secure folder as well.That was kinda big relief to me to finally find out i don't have a faulty damaged device. Now we still have to find out which apps cause bootloops and why tho.
[Galaxy Note 3 Q&A, Help & Troubleshooting] Nani:
In order to be sure : Have you checked the content of .android_secure folder from your phone or from your computer ?

Because as this folder is secured, even if there's something in it, it appears empty from the phone view.

My phone is actually quite stable now and i have put back all my apps and made all the needed updates, included gmail (no apps data on sd card).
[Galaxy Note 3 Q&A, Help & Troubleshooting] danushenko:
I have cleared this folder on sd from PC. One loading was ok (but took a long time), but the second causes problem again
[Galaxy Note 3 Q&A, Help & Troubleshooting] Nani:
So anyone wants to know something weird ?

About all the apps that had data on SD card, which I previously moved to memory phone (using information and move to phone) ?

Using the same way, one by one, I put back data on SD card ...

And you know what ? No boot loop at all !!!

Each try seems weirder ...

Anyway now all my apps are installed as they were in my previously device with no boot loop ...
[Galaxy Note 3 Q&A, Help & Troubleshooting] captainhakan:
I've checked the folder from my Note 3 . But that was after i formated my sd card and i've used solid explorer with " ShOW hidden files" mode . So I'm pretty sure i had an empty android-secure folder when bootloop issue still exists. This doesn't eliminate it might also be a reason for bootloops tho. Android-secure folder and some apps might both be the reason but in my spesific case it was just some apps causing the issue as i already had an empty android-secure folder.

I also have this issue on my SM-N900W8 Canadian note 3 and it's driving me nuts! I've done many testing even single app installs and reboots, I found mx player to cause a single bootloop issue and removing mx player it stopped. So it's definitely app related also. Hope this gets fix ASAP somehow. Can anyone else confirm mx player causing a single cycle reboot? Thanks
[Galaxy Note 3 Q&A, Help & Troubleshooting] androidaddict23:
I had this same issue I factory data reset and it was find I suspected an app I installed
[Galaxy Note 3 Q&A, Help & Troubleshooting] Nani:
I have mx player and no issue at all.

i think it's kind of random.

to be sure :

- put your sd card in your computer then :

- verify if the .android_secure directory is empty. If not, write down on some paper the names of the apps in this directory

Put back the sd card in the phone

- for each apps , transfert all the data from SD to phone (using menu information on apps)

- with a file explorer, delete the directory (it will automatically be recreated).

Should be no more error.
[Galaxy Note 3 Q&A, Help & Troubleshooting] turilo:
seems if i transfer the app to SD Card the bootloop stops with mx player
[Galaxy Note 3 Q&A, Help & Troubleshooting] turilo:
few apps ive tried that gave me bootloops so far are helium by koush, mx player. ill keep trying more
[Galaxy Note 3 Q&A, Help & Troubleshooting] testrider:
Everybody has his own magic recipe to stop the boot loop. :)
[Galaxy Note 3 Q&A, Help & Troubleshooting] xxmelissaxx:
This might sound weird , but on another phone I had (I think it was the s2) I was having the EXACT same problem where I'd take out my sd card and the boot loop would stop ..The problem ended up being a contact saved to Google contacts , I know weird you wouldn't think that would cause a problem ..but it wasn't entered correctly or something like that ..so I just deleted all of them and rewrote each one of them and never got a boot loop again..maybe someone could try that ? Or just go through them and see if anythings weird in there ..worth a shot I guess ..
[Galaxy Note 3 Q&A, Help & Troubleshooting] turilo:
Well I tried taking out my SD card and factory resetting the device to start new without an sd card in the phone, and after maybe 20 apps installed I restarted the device and got a bootloop :/ this is just rediculous
[Galaxy Note 3 Q&A, Help & Troubleshooting] danushenko:
Then maybe you could delete them one by one to identify those which cause bootloop?
[Galaxy Note 3 Q&A, Help & Troubleshooting] turilo:
nah im getting an exchange tomorrow, hopefully for better and not worse lol
[Galaxy Note 3 Q&A, Help & Troubleshooting] danushenko:
So could you report please if this problem will dissapear with the new device
[Galaxy Note 3 Q&A, Help & Troubleshooting] Nani:
I have no more boot loop now, using SD card and data on it. So that's for my side a software/firmware issue.

Anyway what i have done is :

- reset the phone using TW menu (and not Recovery boot because it seems in my case that was not the right way to reset the device)

- format SD card in the phone (or at least delete .android_secure folder)

- put phone in plane mode (to avoid issue if the device reboot)

- install apps

- move any apps installed on the sd to the phone

- put plane mode off

- try reset

That's at least what I have done after many trials ... And after that, I transfert back to the SD card the previous apps transfered to phone.
[Galaxy Note 3 Q&A, Help & Troubleshooting] danushenko:
Thanks. I'll try this. But how can I install my apps when using my device in plane mode and having formatted my sd before? From what source should I install them?
[Galaxy Note 3 Q&A, Help & Troubleshooting] turilo:
ok very strange situation here now, I found an error in my carrier apn settings, the proxy didnt have the ip address, so I put in my ip address, saved the apn, rebooted my phone and umm bootloop stopped! now if this is even possible, that is definitely crazy! ill keep testing things see if i can get it to bootloop again
[Galaxy Note 3 Q&A, Help & Troubleshooting] danushenko:
Can you please write step by step how to change these settings
[Galaxy Note 3 Q&A, Help & Troubleshooting] turilo:
well It depends what carrier you're with or if even your apn settings are correct or not? are you facing constant bootloops when installing apps?

Thanx

I received this update yesterday, bootlooop issue hasn't solved
[Galaxy Note 3 Q&A, Help & Troubleshooting] captainhakan:
I'd like to share my journey regarding bootloops so that maybe you can fix it too. I had bootloops like ever since I bought my new Note3. I have tried for days for almost anything and nothing worked till something did the magic for me. I turned on the device in flight mode(it was almost impossible to start the device otherwise). I formated my external sd within touchwiz. I've returned to factory defaults within android settings. When device turned on I have made initial settings as I would normally. I did not choose the password lock option. Then I've let all my apps download from play store. I have turned off the device and there was still bootloop so once the device turned on after a few bootloops I've uninstalled the apps downloaded from play store one by one. Then I've rebooted the device and voila! No bootloops anymore. I have used the device for a few days without a single bootloop till I decided to copy the contents of my sdcard(I have copied my external card contents to my laptop before I formated my sdcard) from my laptop to my external sdcard. Those files were basically titanium backup files, helium backup files from my previous device Note2. Then I have downloaded helium, dropsync from play store. And restored whatssup from the helium backup files created in my previous device Note 2. I had a system warning message that process has been killed by Google check. But I have checked out whatssup and it was working with my data restored. Then I have used dropsync to sync whatssup folders I have started backing up on my previous Note2 and continued in Note3. I have rebooted and bootloop came back again unfortunately! After a few bootloops my device turned on and I have uninstalled the freshly installed apps(helium, dropsync).I have rebooted and there was still bootloop. Then I have deleted all the new files I copied from my laptop to my sdcard. And i never had a single bootloop ever since. This journey made me think that the bootloop problem occurs because of either dropsync and helium backup process or copying sdcard contents from an sdcard from previous android device. I hope my findings could help some of you yo fix your annoying bootloop issues.

Appears samsung are now blaming app makers for not updating apps to work with 4.3 !!

I dont think its quite right as ive installed all my apps i used on 4.2 and wiped my memory card and ive not had one reboot ...

i still think its down to a conflict with the memory card
[Galaxy Note 3 Q&A, Help & Troubleshooting] shaggyskunk:
I've not had any reboots - and I've installed most of the same apps that I was running on 4.2.2 - I tend to agree with you regarding the micro SD card - But more specifically - WHAT is on the card when you mount it in the N3 and possibly WHEN you mount the card!

I did the full setup and downloaded 99% of my apps - WITHOUT the card being installed. - And like I said - Not a single reboot or bootloop.
[Galaxy Note 3 Q&A, Help & Troubleshooting] Nani:
It could be a 4.3 issue and apps not being updated.

After a full phone reset thru android menu and the deletion of the .android_secure directory on the SD card, i have resinstalled all my apps.

Bootloop was still here. Then I moved to phone all the apps having data on SD, then delete again the .android_secure directory (from the phone).

No more bootloop.

Then I have transfered back the previously moved apps to the SD card.

Still no bootloop.

Weird ...

Since then, i have installed or updated apps. Still no more bootloop.

---------- Post added at 01:55 PM ---------- Previous post was at 01:52 PM ----------

Regarding the boot loop issue, I saw from another thread that Samsung was accusing dev for not having updated apps to 4.3...

Problem is until now, nobody has been able to say if changing the device was correcting the issue.
[Galaxy Note 3 Q&A, Help & Troubleshooting] shaggyskunk:
Yeah - I'm having trouble buying that - I've been running Slim 4.3 with 4.3 Gapps on my N2 - WITHOUT any problems.

I leaning towards thinking that it's got something to do with the way that Samsung/TW interacts with the external SD card - I'm using the 32 Gig Lexar class 10, which previously resided in my skyrocket - But I did a Full Format to Fat32 (Not the quick format) in my pc - Don't know if it makes a difference - But I've got no problems.
[Galaxy Note 3 Q&A, Help & Troubleshooting] mancuk29:
I swapped mine from clove , I got another boot loop after installing my apps however I sorted this by formatting my memory card and ensuring no apps installed on my card .. I also disabled gmail to be sure

Voila no reboot

Still no wiser is it gmail , a memory card issue or apps wish someone would own up to causing us problems
[Galaxy Note 3 Q&A, Help & Troubleshooting] mancuk29:
I think it's a memory card issue once I wiped my card I've had no issues
[Galaxy Note 3 Q&A, Help & Troubleshooting] oaklea:
Well I tries all the 'solutions' to this reboot loop problem....and finally refined the Note 3 today...in frustration and disgust! I'll buy again though once this issue is resolved.

Here's what I tried/found......

3 hard reset of the Note. No change

3 different makes of micro sd. No change

Format SD ......everthying works fine and no boot loop....until I started to place some files on the SD card....(no Apps). A few small folders with backups, maps and charts etc and everything was sweet...booting perfectly......then.....

I moved a load of photographs in folders to the card....BOOTLOOP.

I noticed some of the folders had Picassa .ini files presumably due to the fact that the folders came from my Mac and had been used in Picassa. I deleted all the .ini ......NO BOOTLOOP.

Next......

I thought I was on a roll so moved a load of music files into a folder I created on the card......BOOTLOOP!

At this point I lost the will to live and decided there may be other things to do in life than try to sort out Samsungs problems!

I should add that the Music and Photo files work fine on a S4 and Note 8.... I did delete the secure Android file each time I formatted and had no executable files at all on the card so the comment from Samsung reported earlier in this thread sugesting that the problem is due to 3rd party apps seems to be complete rubbish!

Good luck on this !
[Galaxy Note 3 Q&A, Help & Troubleshooting] danushenko:
I have more than 3000 music files and photos on y sd. When i did the factory reset everything was ok till i havent installed my apps (not on sd, it was moved out from the device while i was installing my apps) - then bootlope issue happened again and again. So it is a conflict between some app(s) and micro sd

Ok heres the update, i got my replacement device today! I did not root or anything yet this is pure stock, no External SD card inserted yet either. I installed over 40 apps at once so far did a restart and not a single bootloop! i downloaded more apps, did a restart and again no bootloop! so next i will try with a freshly formated SD card in the phone and see what happens.

i got my replacement today and guess what? same thing with the home button m8 its going to be tough getting a good one :/
[Galaxy Note 3 Q&A, Help & Troubleshooting] danushenko:
And what about working with the sd card?
[Galaxy Note 3 Q&A, Help & Troubleshooting] turilo:
Ok once again now with the 64GB External Sd card from my returned note 3 (Exfat) without formatting it, I just deleted the Android_secure folder inside from my PC. I inserted it into my note 3 let it sit and rebooted, no bootloop! Then to check properly I factory reset my device with my External SD card still in the phone, set it up and let like 25 apps install from playstore. Even started some apps up also, Rebooted and no bootloop! so, not sure exactly what the deal is here because everything is working as it should be on this device. I will try with root next, but from what I've read many gotten this like myself without root also correct?
[Galaxy Note 3 Q&A, Help & Troubleshooting] danushenko:
Yes I didn't root my device .

So maybe this issue comes with only few devices and I need to change my Note 3 too
[Galaxy Note 3 Q&A, Help & Troubleshooting] turilo:
Could possibly be :/ Thats quite a big mess up from sammy if that's the case!:eek:
[Galaxy Note 3 Q&A, Help & Troubleshooting] shaggyskunk:
Yeah - From what I've been seeing - It's almost a 50 - 50 chance of getting a good one - I spoke to Rogers and they're aware of the issue - but kinda waiting on Samsung to let them know how to proceed - Rogers went on to say that, It's possible that Rogers will get a batch of replacement phones for those who notice the "Shoddy Home Button".

A little concerned about seeing some people who are having issues with rooting & errors after the fact....

[Galaxy Note 3 Q&A, Help & Troubleshooting] turilo:
Yea if I were you I'd stick with a bootloop free note 3 lol I'm sure there is a way to fix these home buttons. I noticed actually on my replacement, it's just the white part of the button moving, not the entire silver bezel of the button like my other one was
[Galaxy Note 3 Q&A, Help & Troubleshooting] shaggyskunk:
Yeah - I'm all for testing - But when there's issues for at least some people with nandriods - Stock firmware that is? - No AOSP Roms - Samsung showing that they are seemingly trying to make things as difficult as possible for Devs..... And the fact that I know that I'm exchanging my phone - The downside looks pretty deep..
[Galaxy Note 3 Q&A, Help & Troubleshooting] turilo:
Alright well scrap everything I said! Seems I just encountered a bootloop and seems it was an app I used before called ninja sms, removed it and was ok again. This is pure bs! Must be app related :/
[Galaxy Note 3 Q&A, Help & Troubleshooting] mb523:
Just figured I'd join in on the conversation because this problem is driving me crazy! Constant bootloop, figured out (at first) that taking out the micro sd card made the phone work again. Went through all of the steps everyone else is doing. I formatted the card in the phone, reset the phone to factory, started over, still happening. As a test, when the phone was not rebooting, I put just a few pictures and songs on the internal drive and the rebooting started again!
[Galaxy Note 3 Q&A, Help & Troubleshooting] Nani:
When you did your factory reset ? Did you do it using recovery boot or using android reset menu ? (for me, seems to have worked better using android reset menu).

Have you any app which could use data installed on SD card ? (in which case you have to transfer data on phone memory then delete the .android_secure directory. It will be automatically recreated).
[Galaxy Note 3 Q&A, Help & Troubleshooting] henklbr:
OK, bootlooping is happening when RADIO is ON!

Why there aren't any bootloops when the Note 3 is set to FLIGHT-MODE?

When it has to do with some bad apps, it should happen also in flight-mode, don't you think?

Note: I'd also bootloops with NO SIM & SD inserted!
[Galaxy Note 3 Q&A, Help & Troubleshooting] danushenko:
So changing the device can't finally solve this problem ?
[Galaxy Note 3 Q&A, Help & Troubleshooting] mb523:
Hi, thanks for your help. I did the factory reset without the sd card in it and before I formatted it. I did it by pressing home/up volume button and power (not sure if that is called recovery boot or android reset menu?) No apps on sd card, just music, vidos and photos.

it seems I get everything working ok but then within a few hours, it starts running into trouble....getting too hot, apps shutting off out of the blue, download issues, the device starts slowing down and not responding to swiping screens, etc. Putting it into flight mode does help temporarily. I just wish there was more information, this seems to be the only website even talking about it. :confused:
