Galaxy Note reboots at least twice a day

Its an amazing device. But it reboots twice a day. I am thinking the problem could be External SD card. 80% reboots happens when I connect my device using USB mode to transfer the music and videos
Does anyone experiencing it and does anyone has solution or work around?

Sometimes it cause by bad contact SIM card. Try clean the card's contact points or replace a new one if your SIM card is many years old.
Seems android phones will try fix the SIM lost contact problem by reboot the device.

It might be a damaged sd card too, it's weird that it happens in that right moment when you plug the usb, try with a different one and see

I have the same problem reboot every time I disconnect it from the pc

My note reboots aleatory from nothing and sometimes really freeze with the screen off and I need to remove the battery to restart :s
Any idea? I really dont want to go change it with a new one because I need to make some kilometers to change it. Was the possibility that it is just software problems and if I flash a new rom it become stable?
The Note come with one old rom (I dont know what rom) and it make some reboots but dont make so many like now. When I connect to a Wi-Fi it say that was a update (16 MB) and I make that update. Then the reboots come with more frequency and make that problem of freeze with the screen of. Today morning I make a Wipe to data and Cache (in Recovery 3e) and reset it. Now it dont freeze but make some FC with the most installed (from markt and Samsung Apps) and sometimes reset with no reason.
TY for any help.
Sorry for the bad english.
EDIT:
I see now. When it is charging(turned off), when it stay "off" (without I see how go the battery) a little time, it freeze. Could be that that's happen when is on and when go to stand-by and it freeze. Anyone know whats happen?

Double post. Delete pls.

Safe Mode!

I'm starting to think I might have something wrong with my Note. From time to time I'll turn on the screen and go to do something, but it'll freeze, then go black and make the chimes sound it does when booting up. At first I thought touchwiz was restarting since it doesn't always make the chime sound, but now I'm pretty sure it's doing a full reboot.
Yesterday I got the freakout reboot, but this time it booted up into Safe Mode! I didn't even know there was such a thing on Android, but see the attached screenshot. It clearly says Safe Mode in the bottom left corner, and it deleted several widgets from my home screens, and in my app drawer it removed most of the apps from the folders I'd created, but left the folders.
Rebooting took the device out of safe mode, but didn't fix my foldered icons or home screen widgets. Pretty annoying.
Anyone else had any Safe Mode experiences? Any idea what might cause a spontaneous reboot into it?

Since you have AT & T in your profile, could it be that you're posting in the wrong thread?

Restart your phone. . My little boy managed to put my note into safe mode (dont ask me how cos i cant work it out how he did it) turning off the phone and restarting puts the phone back to normal

You enter safe mode buy touching the menu button while the phone boots. If you are not touching menu, then some ap/ software is causing this. Try a factory reset to see if that resolves the problem.

No, I have the international Note. I did just buy an AT&T version, too, but haven't started using it.
I did reboot back into normal mode already. I was mainly wondering if booting into safe mode was responsible for removing all of my aftermarket widgets, non-stock app links in the bottom quicklaunch section, and taking everything out of the folders in my app drawer except for the stock apps. I guess I'll start removing apps and hopefully the problem will go away. The spontaneous reboot happens probably once every other day on average, but just to safe mode that once so far.

my phone used to go into reboot loops often and also very predictable. widgets would not load properly too.
The problem as per me is a buggy apps 2 sd move occurring in the phone (reproducible event every single time i recreate that situation).
Solution that i found the hard way after a lot of trial and error and a lot of frustration (needing to repeatedly reload all my apps) was to go into application manager and delete any apps that are present but blanked out without logos. They are always some apps that have been moved to sd card improperly by the phone.
Sometimes when you try to move many apps fast to sd card in sequence then the move isnt done properly and you get application manager showing the app size as 4kb or 8kb or 12kb etc when the actual app size is many times that or even several hundred kbs or mbs. you will need to uninstall all these apps and reinstal them slowly one by one instead of autoupdating market apps which just recereates the problem if the app has already been moved to sd card.
Also another reason not to auto audate apps that have been moved to sd card is that sometimes when you have many apps then this auto update feature when moving it to sd card does it improperly and previous properly installed app after the autoupdate will cause the device to crash because the sd move is buggy and when you go through application manager then the app size show is at variance with actual size and usually just shows 4kb 8kb or 12kb etc instead of usual size. You will then need to uninstal these apps and start all over again.
Since manually moving apps to sd one by one and removing autoupdate for these apps i havent had issues usually.
Once the phone even got stuck on data signal only and would not let wifi on and when ever switched on it would immediately disable it autoatically. couldnt solve this by rebooting or deleting apps or firmware update (not rooted) and had to do a factory reset to sort the problem.
This is not an issue with sd card as even brand new sd cards cause the same issue again. The problem does not occur if all apps are on internal memory or sd card is removed. so guess it is an issue with phone being unable to properly work when many apps are trying to access info on card that it cant access because of improper transfer to sd card. phone then freezes and goes into reboot loops sometimes for 8hours at a go! only sorts itself when the apps are deleted and works ok when same apps are reinstalled properly.
ps: wondering what the safe mode does though and when it is useful to start in this mode? any pointers anyone.

once i accidentally removed the battery while the phone was on. When i put the battery back and restarted it, it booted in safe mode.

Mine just went into Safe Mode. I had rebooted the phone and put it in my pocket whilst it was rebooting. I rebooted normally and got it out of Safe Mode. There is one very annoying thing and one quite good thing that has resulted from this though.
Annoying thing: Many widgets now need putting back onto the home screens
Good thing: All Apps in the App Drawer are now in alphabetical order !!!!

Use app zorter from the market or clear data of touchwiz. All downloaded apps will be sorted automatically.
Well I had safe mode once after unexpected reboot. Still wondering what the reason was.

I have random rebooting issues with my Note as well. It hasn't always done this but it has been happening for the last few months and it'll generally happen once every couple of days. It does seem to be somehow related to moving apps around as mentioned in previous posts because I've had apps fail to move to SD a couple of times and it has rebooted once or twice whilst in the middle of trying to move an app to SD. It'll also sometimes reboot when auto-updating an app as I can hear the boot sound happening at times when I'm nowhere near the phone. I don't have any apps showing up with a dodgy icon at the moment but I have seen some stuff appear like that in the past and the only solution was to uninstall and reinstall the app; although that's only fixed the app in question, it's never solved the general rebooting issues. The phone will also sometimes lock up and reboot when trying to launch application (this seems to happen more often with newly installed apps at first launch, but that might just be a coincidence).
The only other odd thing I've noticed, which might well be completely unrelated, is that the shortcut for one particular app (the full version of "Where's My Water?") continually disappears from a folder of shortcuts on my main desktop screen. The app itself is usually still on the phone and will happily launch from the app drawer, but if I create a shortcut anywhere else it will always disappear again shortly afterwards and it's literally the only app this happens with. The only reason I mentioned this as possibly related is because the app has appeared with a bad icon once and had to be reinstalled again as if the phone had lost track of it on the SD card.
Anyway, I do get the feeling that the reboots are happening when the phone can't find something on SD storage, or when it can't get data on/off the card fast enough or whatever. God knows how you'd get to the bottom of this or solve it though; the ICS upgrade will probably force me to do a factory reset of my phone so I'm hoping the issue will just fix itself as part of that process otherwise I'll just need to put up with being annoyed at it.

Why do icons sometimes go invisible?

Sometimes after booting the phone an icon will go invisible. I can move it and use it as normal, but otherwise I can't see it. A reboot fixes it. Any ideas?
Here's an example with tunein this time

Did you move that app to your SD card? It isn't available until the card finishes mounting after boot. If it is on the card and staying unavailable, you may have a problem with the card.

Not that, I don't move anything to my SD card.

I have the same problem. It first started with the phone icon and it fixed after a restart but now another one is doing the same. It just started to happen earlier today and I hadn't done anything than browsing and listening to music. I'm baffled as well. First time I've seen this.

I have the same problem, but no solutions yet. What happens to me is, it is a couple random apps every time, and they do not fix until re-boot, which then even more go invisible.

Occurred during the second week of ownership for the stock email app. Icon disappeared.

Galaxy S4 I9515 (5.0.1 Lollipop) Battery Drain due to "Android System"

Hi Guys,
I had my second handed S4 since 8 November and I noticed battery draining from the beginning. It's only draining while using the phone, when it's in idle it doesn't drain the battery. Also I found out that "Android System" took about 20%-25% of the battery (about 10% more then the screen, see the screenshot).
Things I already tried:
- Wipe cache partition; made my whole device crash (all apps Force Closed).
- Due to that I had to do a full factory reset; also didn't change anything, still draining
- Yesterday I flashed CM12.1 on my device which was a huge dissaster because the screen didn't respond to anything. So I had to flash Samsung there Firmware on it and I chose 4.4.2.
- 4.4.2 was defenitly better with the battery and there was not Android System eating up my battery. But the WiFi button stayed greyed out so I coudn't use that as my daily driver aswell.
- Now I'm back at 5.0.1 and the battery drain is still there even after flashing another firmware on it using Odin.
I already ordered a new battery to see if that may fix it. There is a chance the battery is false because i can spin it around on a table and it charges even quicker then is drains. Searched the internet for days and tried everything i could find without succes so far. Hope anyone can become my best friend and let me enjoy my S4 again the way it should be.
Thank you in advance,
Can't send my screenshot because I'm a new user, will send it when able to!
UPDATE: A new battery doesn't fix anything aswell.

Already tried, didnt fix it!

I have the same dreaded problem with my Galaxy S4 GT-9515 (Value Edition) running on stock Android 5.0.1 - Samsung ROM. First, I thought that it was a defective battery, replaced with a new one and it still does NOT hold charge at least 1 day. It had SIM Card in it, I removed it for the sake of possibility of bad GSM signal, still the battery drains within a single day from %100 to %0 without any SIM Card in it. Crazy!
I found no solution and it's getting worse.
I investigated the processes and found out that the CPU-hungry process was "Android System", which consumes more than %80 battery when the phone is totally IDLE.
I strongly beleive that Samsung intentionally pushed the last system update (in 2017) to make it unusable rather than slowing it down, as I had another S4 which is GT-9500 runs fine when idle using any OEM battery that keeps it ON almost 2.5 days.
What should I do?

Running out of Internal memory

2 weeks ago, I received a replacement S5 when the screen on my old phone died. At that time I rooted lollipop and everything was running fine.
Today, I woke up and the phone was complaining that it was running out of internal storage. I checked and it was 10.30GB/10.52GB. I deleted some files and brought usage down to 9.7GB. The phone stopped complaining. 2 hours later, the internal card is completely full. I deleted a few more files and again the card is full.
I have rebooted and turned off data to see if the phone might be downloading anything to the card. No luck. I even tried looking at the directory structure in ES File Explorer, but the darn program keeps crashing, probably because there is no free storage.
Does anyone know which directories are safe to delete/what data can be removed? would it make sense to go into the application manager and start deleting data from apps?
What the heck could be causing the internal card to be filling up? browser cache? buggy programs?
I also just remembered something else: when I woke up and unplugged the phone from an over night charge, the battery was not at 100%. I got to work and it complained that it was at 20%. I plugged it in and after 2 hours it's only up to 30%. I turned off the phone and it seems to be charging normally.

This will most likely fix all your storage issues. As for the battery percentage, that may have just been a fluke. I've had it happen once before.

I asked one of the techs here in the office and he suggested I do a factory reset. I titanium backed up everything and did the reset. I then reinstalled everything and memory is happy. Only 6.31of 10.52 is in use. The only sucky thing is that I forgot to back up my noon app and lost a few days of food, exercise and weight. Oh well.
The weirdest thing and the reason I did the reset is that when I opened the card via USB, it displayed only 200+MB of files, but told me it was full when I tried to copy anything. So weird.

When you hook it up to USB, only your personal portion of internal storage is visible to you. The system and data take up internal storage as well, but that's visible to you via USB when using Windows Explorer or any PC file explorer. Doing a factory reset cleared all of the data on the phone, including system data. That's why you have all your space now. If you use Titanium Backup to restore things, then you are most likely going to run into the same issue. If you are done restoring everything you need with Titanium Backup, then follow the link I just posted before it causes insufficient storage.
