Random restarts

The past week I got 3 restarts on my note. First was at home with USB cable to PC to charge it, nothing else, locked screen, don't remember if there was a running app. The other 2 times where on the road, I was listening music on stock music player. The only app I am thinking it could have something to do with this is top deals, even not 100% sure need to confirm got rid of it now let me check it. Anyone else noticed anything similar???

It happened to me few days back. It did not restart but I found it was off. Battery was around 50% and it was on third day after restart. I think it could be remote desktop app called 2X - Note particularly gets slow after runing 2X couple of times. I am on 2nd day without running 2X and I wish to confirm if this app is playing something wrong (btw I didn't have problem with 2X on S2).

Yup. It does happen to many people. "Sleep of death" happened to me several times on stock speeds/voltages. Restarts on my phone seem to be more OC/UV related.

I got mine about a week now and have had several restarts. It was way worse before I ran the update though... Now it "only" reboots 0-3 times a day
I don't dare to root it before I know it software related, but it seems like that since it got better with the official update...
I have restored it to factory defaults etc and nothing helps. I experienced this with NO extra apps installed and with the 4 apps I installed it's not worse. (Don't wanna personalize it before I root OR send it back and hope for replacement.)

Third day and it restarted. It however did not reset System Uptime.

Never had a random restart or sleep of death, in fact I can only recall 1 FC and I've had the phone for 2 weeks now

Lucky you!
Well what I wonder is if I root it is it possible that a custom ROM will fix my problems?

Note keeps restarting, but no like other threads!

Hi,
I have my Note since 2 months ago. It restarted, but only 4-5 times a WEEK. Yesterday, I was browsing Internet and Note restarted. 'Ok, normal I said'. The phone turned on and I entered Internet. Again, it restarted. I wait the phone to start, and when I was unlocking it, it restarted. And restarted, and restarted, and restarted. So I take the sd off and turn on the phone. No problems. Then I put the SD card. Turn on the phone. No problems! Until now. Same happened. Same I did. It restarted only 1 time, then no problems. But I pay too much for this phone (in the country I live) and with my old Ace it didn't happened! It's annoying, EVERY TIME I TURN OFF THE PHONE AND THEN TURN IT ON, RESTARTS! And I have to take off the battery 2 times, put it 2 times, wait for the phone two times, and put the sd card. It's really annoying!! Someone can help me?

I wouldn't say any of that is normal. I think you should consider making a warranty claim.

What ROM are you on? Maybe try reflashing stock ROM on your phone?

I think you can try factory reset if you are on gb or some other safe rom if on unsafe room please don't do reset coz of brick bug

Are you on a custom ROM?
Of not then I'd just get it sent back as it not something you have done.

I didn't root the phone, and it has the original Gingerbread 2.3.6.

I had this issue before. Mine was caused by a wifi management app that i used. Issue disappeared after i uninstalled it. The app is "auto wifi"

If you're completely stock, and still on Gingerbread....and you're ABSOLUTELY SURE YOU ARE ON GINGERBREAD......like REALLY SURE....
Then do a factory reset and use the phone "as is" without installing any new apps for a week.
If you're good for a week with no reboots, then it's surely an app that's causing it. =)

1. reset to factory since you are on GB
2. reformat the sd card, otherwise replace or remove it then observe.
if it still does that after factory reset and without the SD card, then consider a warranty claim.

Note 4 will Auto Restart even not using it!!

Hi,
Everyone here, just got my new Galaxy Note 4 yesterday.
I have encountered this issue, the Note 4 will auto restart after not using it for a while, say 10 to 30 minutes it will auto restart. At first, I thought I was accidentally pressed the power button but I put it on my table not using it for a while it will auto restart.
Latest: I used the Note 4 to call my friend in the midst of the call, the phone auto restarted.
Till now, I still not yet install any program into the phone, still in its original condition.
Anyone here know what's wrong with my Note 4? or have experienced the similar problem in your other phone? How to solve it?
Could this hardware failure or software problem?
Thank you.

No problems here. I suggest you do a factory reset and see if the problem still occurs. If it doesn't, one of the apps you installed is the culprit. If it does, I think you need a replacement.

Thank you for your replied and suggested help.
In fact, I did one time factory reset but after that the Note 4 still auto restarted.
When the phone was in my hand from the shop till now I did not install any program into it.
Anyone know why the phone will auto restart?
Thank you

Go back with your phone where you bought it and ask for a new one!

Maybe a faulty unit. It's their fault. You can plead a compensation tho'.

I am having the same issue, although I have installed some apps on my Note 4. Also, I tried uninstalling apps, and changed some settings. Every time it auto restarts, it reverts back to the settings from before, and shows all of the apps back on the device. I'm not sure what is going on with it, but it is extremely irritating. It doesn't seem to matter if I'm using the device or not. It's completely random.

Check to make sure your battery is seated properly (no loose contacts). Otherwise, it might be a faulty unit. A large batch of Nexus 7s had a similar issue and they all had to be sent in for a warranty repair.

after i removed my sd card and tested for 2 days no random restart and shutdowns.interesting.

My FIL had an S4 that kept rebooting.. It turned out to be his SD card... FACT

Note 4 random rebooting
Greetings all,
I have had my T-Mobile Galaxy Note 4 for a little over a week and I absolutely love it except for the random reboots. The phone reboots randomly, often at at night while on the charger. That is really bad because everytime it does, it wakes me with the T-mobile jingle. I have started muting the audio at night to avoid being awakened by this but that means I cannt be reached by phone while it's muted. I have cleared the cache several times with no improvement and I have done a factory reset once and the problem persists. It seems entirely random. There was one day where I had no reboots. Most days it's a couple or so and one night it rebooted about 5 times durring the night wrecking my sleep. I do use an memory card and I just removed it today as a test. So far no reboots but it's only been a couple of hours so far. This is a significant problem and any help anyone can provide would be greatly appreciated. Likewise, I will post any progress I am able to make to this forum.
Thanks

I have the same problem, I do not have memory card inserted into the phone. It wakes me 3-4 times every night. The store sent it to a lab and they said that the phone is fine and does not have any problem. It drives me nuts.

Greetings again,
I returned my Note 4 to T-Mobile and got a brand new phone, and sim card. I have all my software loaded and configured as with the old Note 4 and it's been about 36 hours now with no reboot. If it doesn't happen in the next couple of days or so, I will probably be pretty confident that the problem is solved. I'll keep you updated.

OP, is it rooted? I have the unbranded Note 4 (SM-N910H), I've had mine rooted for 2 weeks and it kept randomly rebooting twice or so every 1-2 days, now I've removed the root and everything seems to be working fine with no reboots since 1 week. I hope this helps.
P.S. I've rooted using the CF Auto root.
Anyone knows why the root was causing random reboots for me? I've tried with knox disabled and enabled and with both options I get the same reboots.
Edit: Forgot to say that most of the random reboots happened while the phone was idle (screen off)
Thanks.

note 4 restarting
I have the same issue .. my note 4 is auto restarting... i use gear s all the time bu connecting it with note 4 via bluetooth and the phone randomly auto restarting .. yesrterday i didn't connect the gear s all the day and the phone works all the day fine and it didn't restart .. so i really don't know what is causing this problem ! Anyone can help?

Frustrating
I have a similar issue with the Note 4.
A few back, it randomly restarted and I lost half of my contacts and settings. I thought it was a one-off occurrence and re installed all my contacts and settings. Today, it kept restarting and hasn't started again. I called ATT and have asked for a replacement.
Hope the new one shapes up better than this. It sounds like there is a hardware defect in a lot of the phones.

Same here N910CQ, brand new one...

My phone restarts itself at night, is yours also behave like this?

I have a weird problem with my note 4. It restarts itself 2-3 times but only at night. It starts at about 3, 4 am and then every hour or so until 7 am. I hear the buzz on every restart. Also my gear fit connects and disconnects every time with a vibration buzz. It drives me nuts!
Do you have the same problem?
I already tried a factory reset, also disabled the automatic sync to the servers. Also formatted the SD card inside the phone and tried to remove it completely but the phone still restarted at night.
I went to the Samsung center- they sent it to the lab and the lab said that the phone does not have any problem at all- but they did not check it at night.
I'm on the latest firmware N910FXXU1ANJ4
Can you help me? What could be the problem? what can I do???

If it happens again...get a video recorder..record the event...show it to samsung..demand a replacement. My device had no problems what so ever when it was completely stock, or after rooting or when using custom rom.

That is so odd...! What if you tried to video record the phone restarting and show it to the service centre? Maybe with a timestamp so you can stitch together the restarts and demonstrate what happens every night.

I will do what you suggest . I will record the phone on video and show them what it does. This is not normal if I'm the only one who have that problem.

Hope you can exchange a new one
I dont have that problem

I will sue them. This is the only way. Because they are like wall. not possible to prove that you are right

I don't think that there is a solution. There is something wrong with the phone because not all the units faulty. Tonight i will film the phone on video camera to prove it and sue the company. They refusing to refund my money because they claim that the phone does not have any problem.

I have got that issue, but it just turn off by itself while recharging at night

I'm having the same problem with my Moto X 2014. It reboots itself only at nights one or more times. I've trying everything without any success. Did you manage to fix yours?
Thanks!

Do you have any memory management software installed? Some of them kick in when phone is not used for longer time and maybe it deletes something what causes phone to reboot?

If it's only at night whilst charging, it could just be an overheat problem.

Bogs down daily, requires reboot

Really scratching my head here. My V20 gets slower over time after about a day or less, it needs to be rebooted, it's basically unusable and sometimes it's so slow it cannot even be rebooted and have to do a battery pull. Of course I did a factory reset and Tmo even replaced it, but no luck. Any ideas?

Sometimes I notice a lag spike, where nothing will respond. I give it some time and it usually clears up. But I have no idea what causes it.

The only time I experience that is when I was downloading a couple of files using the browser Firefox

I just received this phone a few days ago and noticed this started happening. I've wiped and Factory resetted the device twice.
It can last at least half the day until it starts to slow down dramatically. I have no idea what is the cause.

This is firmware problem. Mine is in the box waiting some decent update.
It's ridiculous that LG release a phone with an alpha firmware. But not only LG, all the companies do this disgusting thing.
Really annoying.

It's only happened twice for me. But both times, I was downloading multiple files in the background. Maybe it's a app taking too much processing power away from the phone...

I constantly get a big lag exiting the dialer with the back button after a phone call. If I hit the home button it responds immediately.

I hate that it lags so bad after a call. I'll go to send a message by hitting the message button, and I sit and wait for it to catch up.

I had the same lag issues with mine. It was constantly freezing as well. I did notice when it was happening it was really warm. So I'm not sure if the added heat was causing it or not. When it was happening I checked memory use and nothing was eating it up other than the os. I got T-mo to replace it and so far no issue on my new one, fingers crossed.

The only time I get this is if I'm downloading multiple files in the browser or installing multiple apps from the Play Store. It clears up right after that though.

I pulled my sd card out and running it without, but still, molasses mode returned.

Mine is not as bad but I have to make sure to reboot first thing in the morning otherwise sometime during the day, it will slow down or just freeze and I need to do a battery pull. Which is a pain of you have a case. Or in the car using it to navigate.
