Taking the SimCard out works for me!

THANX NANI ! :svetius:

I tried copying apps from external to internal.. no dice..

BUT this.. this works for me.. take sim card out boot phone up and put it in airplane mode.

Power down then insert sim card boot up.. presto.. boots properly..

If I forget to put it in airplane mode before reboot I just repeat this step.. works for me 100% of the time I tried it at least 5 times..

This will be fixed with a firmware update.. I too have a UK version... untouched.. imported.. I'm in Australia.

we shouldnt have to do this , it should work out of the box without trying to get it to reboot without the loop

not impressed but hope samsung fix this asap

i have my second handset coming tomorrow , im going to install all of my apps on my handset before i install my memory card and see if that sorts it without the boot loop .. if not its going back for a refund and im getting something else (Not sure what else as nothing beats this beast)
[Galaxy Note 3 Q&A, Help & Troubleshooting] mancuk29:
Question for you guys and ladies who are having the issue what size memory card are you using ??

Notice that henklbr is using a 64gb memory card ... is everyone else ??

wonder if its an issue with the memory card size ??

another question did you all hve your memory card in when you were installing apps ??

has anyone tried to install without the card and then put it in once installed

i wonder if its to do with some of the apps going onto the memory card

its damn annoying and i hope samsung hurrys up and sorts it as i dont want to jump through hoops to restart my expensive smart phone

I am not rooted , do i wipe data and cache in the power up menu (power, home and volume up (or is it down) ???

never been rooted so have never seen wipe data cache before if you can help
[Galaxy Note 3 Q&A, Help & Troubleshooting] fethi2:
I am not rooted too so you have to follow these steps

1- take the battery out ( just to make it happen correctly for next step)

2- Hold down the power + Vol. down + home button till you see samsung logo

3- Let go all the buttons and you will see a screen in black lying down android with exclamation mark on belly

4- From there you will have to move down the cursor with vol. down button and when the cursor is on wipe data / cache push the power button.

5- Say yes with the same type movements

6- Now you formatted your whole system and delete everything

7- Hope works for you and enjoy..

Do u have a memory card in ? If so what size ? If u did , did u install your apps with the card in ?

I wonder if it's a memory card issue
[Galaxy Note 3 Q&A, Help & Troubleshooting] Nani:
As there's not boot loop on "plane mode", I tried to reboot with "plane mode off" but without the SD Card => phone goes in boot loop.

So I tried withoud the SD Card and without the SIM Card => phone made 2 reboot before being able to stabilize.

So, after a hard reset, there's no issue even with SD card and SIM inserted ... But after software update and apps installed, phone goes insame ...

As SIM Card and SD Card are using the same slot, maybe there a "memory conflict" ... Something that could be related to the firmware (as from a fresh start there's no problem).

[Galaxy Note 3 Q&A, Help & Troubleshooting] Nani:
I was one of the first postings here regarding the boot loop issue.

After having found that reboot in plane mode was ok, I tried what almost everyone has done : hard reset, moving apps from sd to phone then from phone to sd ... Bla bla ...At last no more boot loop.

And then I saw your post and remembered having put off the "Always allow scanning" ...

So I put back the option and guess what ? Boot loop are back.

I again put iff the "Always allow scanning". No more boot loop !

As I don't understand how all this is related (SIM, SD Card, plane mode ...) what I can say is that YOU found the issue regarding the boot loop.

Anyone having boot loop should try in order to confirm ...

Good job !

WOW! This is an even better tip then using airplanemode before reboot! I can confirm the bootloops stopped bij unticking the 'Always allow scanning' Wi-Fi setting, thank you!

It seems that WiFi is the right problem for these bootloops (your procedure worked for me on SM-N9005).

There is also another problem with Wifi when we are taking pictures (several lines displayed on screen) =>> http://xdaforums.com/showthread.php?t=2471756
[Galaxy Note 3 Q&A, Help & Troubleshooting] programatix:
I too am encountering bootloop, but not on every boot. Once the boot-loop occurs, it will keep occurring until I manage to stop it. After that, it might be safe to reboot... until it occurs again.

Anyway, I only encountering bootloop if I have the SIM card inserted. Without SIM card, it never happen.

The following always stop the bootloop,

If the phone restarts after showing the lockscreen, quickly unlock the phone once the lockscreen appear. This will stop the phone from restarting. Weird eh?

If the phone restarts before showing the lockscreen, remove the battery and SD Card. Turn phone on. Phone might restart, but most of the time, at least the lockscreen should be shown because without the SC Card, lockscreen seems to appear faster, thus it would almost always restart after the lockscreen is shown. Quickly unlock the phone and that should stop the restart. Reinsert the SD Card.
[Galaxy Note 3 Q&A, Help & Troubleshooting] troile00:
Well, the solution I quoted below ultimately worked for me. However I wanted to add to my previous post as well (also quoted).

When I started my phone in airplane mode, it booted fine. I then turned off airplane mode, went into application settings, and started to move certain apps from SD card to STORAGE. In the middle of moving one of the apps, the phone rebooted on its own and started looping. Once I uninstalled all my apps that were stored on SD card and reformatted the card, the bootlooping stopped. However, the phone would reboot itself one additional time before stabilizing (not really a loop).

I guess the point is kind of moot since turning off the automatic scanning worked.

[Galaxy Note 3 Q&A, Help & Troubleshooting] TJCacher:
My understanding is that "Always allow scanning" means the device will continue to scan for available wifi connections even when you have wifi switched off in the settings. Really doesn't seem like a particularly useful feature IMO, and the scanning would obviously require the device to power on the wifi radio occasionally to perform the scan, with at least some (probably negligible) impact on battery life.
[Galaxy Note 3 Q&A, Help & Troubleshooting] mb523:
Wow! It works, thank you so much!!!!! I unchecked "Always allow scanning" and didn't even remove the sd card and no bootloop!

Don't have any issues with wifi Always Scanning.

Disabling it may be a workaround - but there's got to be something else going on for some people...
[Galaxy Note 3 Q&A, Help & Troubleshooting] TJCacher:
Agreed that this solution is just a (very effective) workaround, but it seems to be a very low-impact one.

If I'm not reading too much into the exact wording of the option, all we're giving up is the ability to be notified when wifi networks are available *even when we've explicitly turned wifi off*.

The wording suggests that scanning will be done if wifi is on, regardless of this setting.

If so (and experience tells me it *is* so), this seems like an option very nearly without a purpose except to waste battery. If you want scanning when out of wifi range, just leave the wifi radio on, which is how I suspect almost all of us do it anyway.

I am having this issue even without an SD card. I have factory reset my phone now. Lets see if it works. Has samsung released any firmware update recently which may have fixed this issue?
[Galaxy Note 3 Q&A, Help & Troubleshooting] kriszty:
same problem here , ubmj3 firmware installed. i have random boots 1-5 time,s a day
[Galaxy Note 3 Q&A, Help & Troubleshooting] Runamuck0870:
I'm getting random reboots and the three-button restart isn't working. Actually, I say reboots but I really mean I'll hit a button or icon and the screen just goes black and the whole phone instantly shuts down hard. I have to remove the back and do a battery pull to bring it back to life OR plug it into the charging cable to turn it back on. This is with a battery of varying charge levels...95%, 90%, 80%, 20%, etc...doesn't seem to really matter.

I've been uninstalling every single app, reinstalling them, trying to run the phone with an SD card/without an SD card, some apps on the SD card, all apps in memory, etc. The only thing I can possibly tell is a common theme is a service called "Nearby Locations" (which I cannot kill) seems to eat up a bunch of battery about 10-20 minutes prior to the crash. But not so much battery that I'm powering down....it just crashes to a hard-lock.

Only had the boot loop (constantly cycling through the Samsung boot logo) situation happen one time.

Not the same as reported by others, but troublesome nonetheless.
[Galaxy Note 3 Q&A, Help & Troubleshooting] ultramag69:
How the hell did Samsung stuff this up like it did... I used to reboot my Note 3 with trepidation and hope after a few minutes of looping it would actually start up, 9 times out of 10 it would. It'd take up to and including 10 minutes of looping to stabilize enough to stay in Android.... In fact trying this was a leap of faith as I'd sworn to never reboot again....

This is a pretty major bug on Samsung's part for a Flagship phone....
[Galaxy Note 3 Q&A, Help & Troubleshooting] Runamuck0870:
So I have had the SD card out of the N3 all day. Didn't get a single reboot for over 7 hours...new record. Then I picked up the phone, started to enter in my pattern to unlock it, and phone crashes to black screen hard lock.....but wait, this time, it actually did a full reboot by itself. Its typically just been a hardlock crash to black screen and I had to yank the battery.

So this is, in a way, progress. Maybe having the SD card out of the unit allowed it to reboot, but having it in makes it lock?

Do I need to use the "format SD card" option you think? This is a Samsung 64g SD card.
[Galaxy Note 3 Q&A, Help & Troubleshooting] programatix:
I would recommend that you first try to reformat your sd card using your phone (copy out the content first). If the problem still occurs, then factory reset the phone.

Btw, random reboot can also be caused by faulty sd card where the system reboot if multiple read error occurs.

N3 Boot Loop Despair..

I am two weeks into the nightmare that is my Note 3; currently on my 3rd device (delivered yesterday) & is suffering from the same boot-loop issue. It's a SM-N9005 purchased on contract with Three. These issues becomes evident when either a) the handset reboots itself or b) if you manually perform a reboot. Usually (though not always)the carrier flash screen pulses continuously with occasional half second bursts of the unlock screen. If you're ultra quick, you can unlock the desktop just in time for the next loop to start. The only way out is to perform a factory reset via recovery. I think (but cannot prove at the moment)that the problem is app specific. I'm currently installing apps, one at a time, then performing reboots in an attempt to nail the app. I have a suspicion (but again, no proof) that there may be more than one bug/trigger. Swapping or omitting an sd card makes no difference. Not the Note 3 I was hoping for..
[Galaxy Note 3 Q&A, Help & Troubleshooting] Runamuck0870:
I suspect its also an app conflict with the firmware or OS. I'm trying to narrow it down to one of the Google, Samsung or Verizon apps that came pre-installed on the phone as Im encountering this even after a system restore.

Out of curiosity, I wonder how many people are having this issue and also have a Galaxy Gear watch?

My config (minus all my installed apps):

-Verizon Note 3 32gig

-Galaxy Gear watch

-Installed Samsung App store

-Installed Google Play store

-Installed Visual Voice Mail (from Verizon...its their app)

Using everything else stock. Touchwiz, Samsung + Verizon + Google apps + Amazon apps. Everything came pre-loaded on the phone.

Overload / Timeout Issue?

I have the same problem with my european device from france. Removing the SD card helps every time - but this isn't new - you all know that solution.

For the statistics: I'm using a new (never used before) 64MB class10 card from Sandisk and the only content are 20 songs from Spotify in the "Android" folder.

Instead of doing one factory reset after another, I tried a different approach and analyzed your various solutions:

- turning off "always allow Wifi scanning to assist GPS" helps

- turning on Flight Mode helps

- removing the SD card helps

- factory reset (removing apps) helps

- removing files from the SD card helps

- use a launcher that is loading slower/in a different way

But are these solutions really connected to the problem? I don't think so - my guess is that you just have to do something to stop your system from overloading with different tasks during boot. It doesn't matter if you relieve the system from scanning the SD-card, relieve it from scanning WiFi networks or relieve it from connecting to your mobile provider. You just have to reduce the load during boot.

To validate my assumption I simply stopped 50% of my apps from starting during launch with BootManager (by defim). Before I did that I got a boot loop every time the SD card was connected. Afterwards I did 10 reboots, tried to download more songs in Spotify, tried to open many apps, etc. - and the problem is gone.

I'm not very deep into android and what happens during the "Samsung logo", but it seams to me that the device has problems if it gets to much work at once. Is it some kind of timeout, that is too low if the system has to finish many tasks at once? Is it some (memory) bandwidth issue? Maybe someone else can explain possible reasons. My amateur guess is, that Samsung has to increase some timeout values or queue the tasks during boot.

I haven't had time to completely read through this thread...but

I have this issue on a N9005...it has NEVER had a sd card inserted.

Mostly it just seems to restart itself...sometimes apps crash but it seams very random...and it can be any app or process that crashes..no specific one..I don't have many installed, and none are unusual. Mostly popular apps such as Whatsapp..Kindle..

The first few days with this device was problem free..now it happens constantly.

Removing battery does not solve problem..

It sounds like many of you are able to remove the battery then reboot the device normally. With all three of my devices, removing the battery, replacing it then reboot still results in boot looping once it's started to misbehave. The only way out (that I'm aware of) is to factory reset & start the entire sad saga from scratch.

---------- Post added at 08:39 PM ---------- Previous post was at 08:26 PM ----------

Unless there's more than one issue (quite likely) I can confirm that this problem can be present in a device that has not been anywhere near an sd card. Using an sd card does seem to make the device misbehave more often but it is not an essential component in recreating the bug.

---------- Post added at 08:52 PM ---------- Previous post was at 08:39 PM ----------

My device has been ok all day (first time in 2 weeks).. i have no sim card installed but am tethering to another device when out & about & just using wifi at home. sd card is installed, although not currently auto updating apps from the Play Store. This is the best ive managed over three devices.

[Galaxy Note 3 Q&A, Help & Troubleshooting] Runamuck0870:
No, that fix doesn't resolve my issue. At all.

1) I have no SD card installed. At all.

2) I have disabled wifi scanning.

3) I get random crashes of the phone to a black screen. Only yanking the battery unlocks the device.

4) About 50% of the time, after yanking the battery and restarting, it gets stuck in a boot loop. The other half of the time it boots, I put it into airplane mode and can run it with WiFi only for any random period of hours before it locks up and I'm back to square one.

The fix mentioned works for SOME, not all. Even if we all had SOME of the same symptoms. There is not yet a cure for this.
