Phone restarting randomly

Every once in awhile, I will look over and notice the Roger logo popped back up on my phone which means its restarting. No idea how much this does in a day but I have caught it a couple times in the past few days. Anyone have this problem? An excuse to get a phone replaced?

yup..happens to me on average around 3 times a week.
i launch an app..the screen goes blank..suddenly i notice the phone has restarted.
maybe low on RAM or too high temperature

Me phone has only done this once to me after I cleaned too many built in apps from my phone.
Other than that my phone has never rebooted.
Swyped from my rooted X10i using XDA.

My phone had restarting problem when i used aHome home launcher. After unistalling it, never happened again

Weird. My phone has never done it while i am using it. Its always done it when sitting by itself on a table, not running anything.

If you guys read the SE support site, you'll know that it has to do with the phone running out of memory because of too many apps running at the same time.
I know that there is a group here who does not believe in Advance Task Killer app, but I haven't had this issue after starting using this app. And, I'll repeat again, it helps me conserve the battery, not matter whoever who keeps saying that it is useless for that purpose.

It reboots even if you have a lot of memory free. This morning it rebooted after 30 min from the first boot and I didn't use it.
Ciao Angelo

noticed this happening quite a bit over last 2-3 days, not sure if its been caused by program update, possibly adw home.
today has been the worst, disconnecting and reconnecting almost every minute or so.
gonna try switching 3g off see if that helps. really annoying, makes browsing a PITA.

Mine restarted itself about 20 minutes ago haha.
Is this a problem for rooted phones mostly?

I personally found that it happen when I connected to Wifi.
That's for myself.

X10 Restarting
you showld try to turn off the WCDMA mode, after turning only GSM mode it never restarted again, and if i turn it on goes back to restarting every once in a wille, especialy when connected to my car's bluetooth.
try it and give feed back.

Started happening to me after I stopped using advanced task killer... maybe it happens when it runs out of ram?

Don't your phones get extremely laggy without ATK? I usually don't exit apps when I'm done with them, I just press the home button, and open up more apps, so I can't go without it...
As far as I can recall, my phone's never restarted on me...

In the last couple of days it is happening to me too.
I stop using the phone for some time, and then it just restarts itself.

i just bought an x10 yerstday and ever since the recent update it has continuously rebooted on its own when browsing the net and playing music.
This really bugged me since i didnt know whether it was a faulty set or the new update was the problem. after going through various threads on various forums i realised the problem is very common.(unrooted before and fully factory unlocked)
So here is my Solution. it has not restarted yet after doing the following
1. Rooting and updating to latest firmware R2BA026
2. Installing Auto memory manager
> Setting it as follows
FA... 2MB
VA... 2MB
SS... 4MB
HA... 5MB
CP... 6MB
EA... 6MB
3. Installing Advanced Task Killer (Using it as normally as u could do)
> Untick Superuser permission
> Untick Auto Memory Manager
Dont let the memory fall below 15mb always check Auto Memory Manager and then use ATK.
Please tell me if this worked for you. it worked for me

I solved my reboot problem with Reset to factory defaults.

Tried this, also tried resetting using seus and still it continues, think my phone has a fault now, I'm now running latest o2 uk fw (26).
If I'm on 3g it will cycle being connected and disconnected almost constantly, makes using net impossible, if I set it to use gsm only everything is fine. Could be o2 screwing with 3g where I live but I don't think so some how, not for this length of time!
Any one have any ideas? Failing that its gonna have to be sent away :-(

Ok so I wasnt a believer in all this r/s crap, but I alsmost shat my pants last night when my phone r/s on me during a call. Now at that time its wasnt on wifi but it r/s on me...i dialed again and after a few mins it r/s again. This is pissing me off. Any solutions.???
I guess if it continues then imma jump ona new phone.

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.

No deep sleep

All of the sudden my phone refuses to go into deep sleep, it stays at 300mhz according to cpu spy. Not even if I switch to airplane mode the deep sleep works. This has happened a few times in the last week. A reboot fixes it for a while. Do you think it's an app that is misbehaving? Has someone else seen the same thing on their phone?

I had the same thing once I got my Note 4. Turned out that it was my micro SD card, which I popped straight into my new phone from my old phone (an LG). It may or may not be your cause too.
I ended up reformatting it through Android (after copying all my files to my pc). After that, I put all my data back on it. It's been about a month now with my phone always deep sleeping.
If you have a micro SD card in your phone, then remove it for a while to see if the phone sleeps. If so, then backup any wanted files from it, pop it into the phone, and reformat it. Afterwards, you can put your data back on it.
If this isn't your problem, then yeah, it could be an app.

I don't have any SDcard. Hopefully it is an app that is causing the problem. Right now I have uninstalled all the apps that I have installed lately. Let's hope this helps.
The problem seems to start after I charge the phone and pull if off the charger. But as I said, it started last week. I haven't had the problem before and I bought the phone in early November.

If it didn't do it before, then it shouldnt be a hardware problem unless something just randomly broke. As long as the phone isnt getting real hot or anything weird like that, then that shouldnt be it.
I think it may be an app. If uninstalling everything fixes it, then you can reinstall the apps one by one until it happens again. Wait like a day inbetween reinstalls.
If that doesnt help though, then do a factory reset (last resort).
GOOD LUCK!

My problem seems to be fixed now. I did uninstall some apps but that didn't seem to help. I then turned off the phone, pulled the battery for some minutes, put it back again, booted to recovery, wiped cache and then restarted. Since then it's been OK. I have an uptime at 350h right now. It must has been something that had got stuck before. Hopefully it doesn't happen again! Now I'm waiting for lollipop

Anyone getting random restarts/reboots?

Since I got it, I have had about 5 random freezing and complete restarts. Once when YouTube was playing, the audio froze and produced a horrible buzzing sound then restarted.
I did a factory reset and it has happened twice since. I'm wondering if I have a faulty SD card...
Anyone else?

I got mine on Monday and so far no problems

Do you have an SD card in yours?

That happens on my daughters Nexus 10 tablet, it definitely is YouTube and the high definition videos that cause that, it's unfortunate to hear that is happening on this phone.

No issues here or with YouTube. Yes i have sdcard.

yea! same here. i have random restarts!!! i thought it's just me. and I have SD card inserted.
this was me playing games... Fate/Grand Order in particular... i don't have sound on, so I don't know if what's happening...
the phone just goes black, and then the samsung boot logo starts.

I have no issues with g935t w/ sd card

my restart doesn't happen often, maybe like once every 2 day... and almost always playing games or was just playing games... i wonder what's wrong X_X

Only had one freeze and that was when it first booted and was restoring apps. I was uninstalling apps at the same time it was installing them and it froze for like 10 seconds. Other than that no issues.

No freezing so far. I've had my S7 Edge since Tuesday and I'm using my same SD card that was in my S5. I've watched YouTube several times as well as played several games ranging from Mobile Strike to GTA Vice City.

same here. I got my s7 edge on Wed eve. setup everything. No Issues then. next day morning on the way to work, it got restarted for the first time. While walking to Office, it restated couple of times. no specific pattern to it. If I try to do anything, it gets freeze and after few seconds, it restarts.
Couldn't check if it got restarted while at work. but again in the evening, I made a samsung Pay at a store and while driving back, it got restarted. Then at another store, it keeps on restarting after each reboot. Device gets hot as well. really hot.
Tried factory resetting, but immediately after I log back in, it restarted, at the same place.
I turned on Airplane mode and then device cooled off, and it ddnt restart after that. After 15 min or so, turned off Airplane mode, and device ddnt restart yet when Iam writing this now, almost 3 hours later.
Starnge thing is, it never gets restarted at home. it always happens when Iam outside. Something to do with the network? Im on ATT.
another issue, even for small tasks like browsing websites, device gets hot. Hot enough that you will notice.
Not good sammy. Iam a fan of you since 2011 and none of galaxy had issues atleast from day 1.
Iam gona wait a day more, if it still restarts, I dnt want them damn warranty/replacement. Iam gona get iPhone6. I dnt like ios, but atleast it wont die on me like this.
Woah!!! as iam writing this, it got restarted now. WTF! Guys pls stay away from s7 pls!

I had one really random reboot. Next the frone has issues with enabling fingerpring authentication in Play. It stops responding and anter about 15 seconds reboots.
