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

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

[Q] Nexus 4 randomly turning off, intermittently not being able to restart

Hi guys,
Not exactly the most positive of first posts but here we go. There's a problem with my phone that I can't find the solution for...
Essentially my phone randomly turns itself off (no power down sequence, almost as though the battery's being taken out if you know what I mean) and then it has difficulty in fully booting again. For some reason it also likes to revert my wallpaper back to the original as stock.
The first thing that I thought of was malware, with the wallpaper - so I tried a couple of anti-malware apps to no avail. As my device was rooted, I then flashed back to stock, locked and unrooted it and checked the behaviour. Again to no avail (then again I've never rooted/unrooted so this may have been done incorrectly). By the looks of it, the worst case scenario is a problem with battery connections/hardware...
So the question is have you guys come across this before? Is there a solution to this or is Google/LG going to have to give me a replacement?
Many Thanks.

Weird, I just had this happen couple hours ago, I was watching a video and close the app. I press the power button to put it to sleep. Just like 20 second later, I press the power to wake it and it don't do anything. I had to hold the power button to turn it on. I check the battery status afterward and it looks like it drop between 5-10 percent in the chart after it turn on. The battery must have failed or something. This also happen to my wife phone couple weeks back, although she had to do a hard reset(power+volume up and down) it have not happen again though.

Hello
First of all, welcome to XDA community!
Now, have you done anything with your phone? As in, root it? Flashed custom kernel? Flashed custom ROM? We would love to help, but you need to provide us what we need

Okay, here's what I had done when this all started:
- Rooted and unlocked.
- TWRP custom recovery
- Standard Kernel, no custom ROM.
I've reverted as much of this back to stock as possible through a nexus tool-kit, but it still has the issue. If I'm missing anything out let me know.

Did this happen before you had the phone rooted? Also did this happen one time only or happened multiple times? I also had this problem, but just turning off and not turning back on part. But that was only one time event and I believe it was because of the custom kernel.

This started yesterday, and I rooted it as soon as I got it 2 weeks ago, so I don't think the root has caused any issues. It's now happening rather often, to the point where it's unuseable

That's odd. Did you download any apps recently that might've caused this issue? Maybe root apps?

The only 2 apps that I downloaded the day before were cerberus and titanium backup, both of which are well known. Either way they were the day before the problems started.

Doubt that these will cause any issues, but could you try uninstalling Cerberus just in case? Thanks

Well, after completely reverting the phone back to its stock version and pretty much everything else, it's still doing it - which surely points to a problem with the chip (or something). So, I've contacted google about a replacement and so far so good - got through in 5 minutes and sorted out the RMA and everything, should be delivered in the next few days.
Thanks for the help anyway. I'm going to avoid rooting this one for the time being to see how it behaves.

I experienced "random shutdowns" and even posted about it here. Turns out it was my belt holster that was somehow the culprit. I don't know if it was mashing some weird button sequence to turn off the phone, or if the magnet interfered or something else, but as soon as I got it out of that holster I had no more random shutdowns.
I doubt yours is the same problem but I thought I'd post mine.

Funny I had the same thing happen to me last night. I was using the phone put it down for a minute or two and then could not wake the phone. What was interesting was when I couldn't get it to turn on I plugged in into the charger and let it sit for a few hours. When I was finally able to restart it using the the power, vol button the battery was at the same level before the incident. In other words whatever happened prevented the battery from being charged. I am stock and rooted and haven't loaded any new apps in over 2 weeks

I have almost the same problem as the op but I do have a shut down sequence. It does randomly shut down itself. The first thing I got the phone I rooted it and it was fine working on modaco for 2 weeks then one day it kept shutting down upon boot until like 10 tries later I successfully got back in but lasted only a few mins and sometimes hours. Im gonna rma this pos and I hope I can get it replaced soon. I try it with stock rom and kernel then modaco with stock kernel then modaco with faux kernel. Same problem.

I had these problems earlier ... I just gave HARD RESET by pressing power key for more than 5 sec.
Then i figured, it was due to Undervolting ! and Processor going to a DEEP SLEEP all together !
So i removed UVing and it was cool since then ! ... Although my signature says the rest !

I bought my N4 about 2 weeks ago, and it has turned itself off 3 of the nights I've had it. I don't have any hard evidence, but I have a theory on why it's doing it.
At first I thought it was because I used a Motorola usb cord instead of the stock cord because I read some people's theories on the internet, but it happened again (twice) after using the stock cord.
It seemed like it only shut off if I left WiFi turned on when I went to sleep (even then it was still a random occurrence). I went into my advanced WiFi settings and noticed Wi-Fi Optimization was turned on with the text "Minimize battery usage when Wi-Fi is on". I thought it might be the problem, so I turned it off. I left WiFi on last night, and the phone was still on in the morning. Again, it is still a random occurrence even with WF on, so I'm going to leave WF on at night for a few days/weeks and see if it happens again. I'll post back with results.
If anyone else has already tried this or has figured out a solution, let me know.

The same happens several times a week with my nexus 4 running latest cyanogenmod. I will revert it to clean stock in a few days to see how it goes. I don't think that is a hardware problem but time will tell.

Don't know if anyone is keeping up or cares, but I wanted to update and say that this did not fix the problem. 4.2.2 also did not fix the problem. I guess I could try getting a new one from Google.

My wife and I are both having this problem. Hers is completely stock, I'm unlocked and rooted. I was hoping it would be fixed with 4.2.2, but if it hasn't then it maybe time to get replacement N4s
I can't imagine this issue is very widespread, since there have only been a few threads about it. Its a big nuisance especially because it usually happens at night when I'm expecting my alarm to go off at night.
I hadn't wanted to send for replacements since it seems like a software issue but I'm getting fed up.

Just had this problem occur with my N4 last night..... Phone is 2 weeks old.
Went to bed, plugged in the phone to charge [it was at about 50% or so, so not exactly low].
Woke up at 8.30 wondering why my alarm didn't go off at 7.30.... looked over and the phone was off.
It also didn't want to turn back on either. Took about a minute of holding in the power button for various amounts of time before it finally kicked to life [at 100% charge too].
This is going to be a real problem if this problem reoccurs. At home I have a clock radio but I travel a lot and rely on my phone to wake me up!
Here's hoping we can start to identify what is causing this issue. All I can add is that it is not low-battery related.
As stated in the sig. Phone is unlocked/rooted with stock rom.

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.

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...

Random shut down

Today I picked up my phone up to send a text and it was no longer powered up. It had randomly shut down.
When I switched it on again I noticed it has lost its battery stats so looks like they were reset or lost. There were no user apps installed on the phone either.
Have you had a similar experience?

You could try to reset it or take it back. Could be defective!!!

Was it somewhere it was hot? Maybe the phone got too warm and hit the shutdown temp?
Honestly hard (read impossible) to tell you what happened. Have any more info / logs?
I haven't had any issues with heat or shutdowns at all. I get 6+ hours SoT every single day at 75% brightness. 100% stock and unrooted. I use my N5 for all the modding aspects like V4A, Xposed, etc. I want this one for Android pay.
Anyways my uptime has been running since I unboxed it on 11/9/15. No issues.

I actually had it reboot in my pocket yesterday on the first day i had it but I already installed a custom ROM so no testing it out now.

It was only room temperature. Here in England at 18cc so not too hot, but good point.
I read about the same thing happening with a N5 and it turned out to be a defective mother board.
Guess I should return today then... Bummer

If you just got it, might want to see if it happens again. I had one random reboot the first day and its been fine since.

My phone has started doing the same thing. Twice in 3 hours.

Same here...... 3 times reboot..... And now 2 times shutdowns.

I started having random reboots after I installed greenify. I tried several settings but had the same problem. It rebooted 5 or 6 times a day. I uninstalled it and haven't had any more problems.

I had my phone shut off yesterday and wouldn't boot until I plugged it in (it was at 80% battery). I then noticed that once it booted, it had deleted all of my paired Bluetooth devices.

Was just having the same problem but it was happening every 30 seconds to a few minutes. Deactivated greenify's device admin ability and now it's gone. Hopefully it stays that way, though if it comes to uninstalling it, that's fine since there don't seem to be as many background apps running on the 6P compared to my verizon LG G4.
Nevermind had to uninstall it.

Shut down, and a little warm
My nexus 6p shut down nearly every day, I just picked it up and it was shut down, I looked under battery and I could see it has been shut down for hours.. hope somebody knows anything about this problem.. I don't think a hard reset will help, because when I got the phone I installed all the update to Android 6.01 (MMB29M) and then I did a hard reset to make sure the phone was as good as it could be..
But maybe I'll try one more hard reset, just to be 110% sure

I'm having this problem too. It happens a couple times a day, and I think it always happens right after I pull it out of my pocket and try to unlock it. I'll feel the vibration from the Nexus Imprint fingerprint sensor, but then the screen doesn't turn on. So I try the power button, and nothing happens because the device is suddenly off. So then I hold down the power button to turn it on, and it boots normally.
Someone mentioned this happening with stock software, which makes me think it's a hardware problem, so we'll need replacement devices. However, I do have Xposed and GravityBox installed, so I need to rule those out first by removing them for a while.

I've had the phone for two weeks now and so far this happened twice.
The only two things that come to mind:
- enabling SRGB in the dev settings
- using a bluetooth headset
Has anybody pinpointed whether this is a HW or SW issue!?
How common is this ... I've seen ppl complaining in this thread and in Reddit also on random reboots as well
Thx

Still happening...
I am having the same issue. Did the reset to factory with no help. Phone was not hot, was sitting on my desk with 81% charged battery. This is the 3rd or 4th time in a week it just shuts itself off for no reason. Has anyone found anything??

I'm having this problem too, now on DVP 3 it's even worse. But I notice today that alarm clock works, but the screen won't. So I think is a SW related, the screen won't wake up, and after a while if you press the buttons the phone reboots. Anyone have e ideas how to fix this?

facing this problem since may security update, on purenexus , dirty unicorn and rr rom. dont know if it hw or sw or simply power button getting pressed accidently.

I think I need to reopen this post, coz' I've been facing thif problems for so many times this week so I google around and come to this post.
Has anyone come to a workaround or point out if it is software or hardware related yet...? If it's hardware then I think I'm gonna go for a replacement then!!!

If you haven't done so already, go vote in the "early shutdown" poll

Note 4 (T-Mobile) Lag, Freeze, Crashes, Restarts.

This is my first post on this forum. I searched around here for a solution, didn't really find one matching my problem. I am not a phone wizard or anything like that either. So I'll try my best explaining my problem.
First things first:
Phone: Note 4
Model #: SM-N910T
Android Version: 5.1.1
Rom: Stock Rom
Rooted: Rooted Once and used a custom Stock T Mobile Rom Once.
Here's the ROM I used at the time: http://forum.xda-developers.com/not...10tuvu1cog2-debloated-deodexed-stock-t3175406
Recently I So recently my phone out of the blue started lagging, freezing, and restarting itself. I didn't download any applications or anything like that for it to freeze up. I was currently then on the custom ROM I have mentioned above and it was the updated version. I have tried everything to my knowledge to try and fix the problem. I have tried going back to stock T mobile ROM (currently on stock rom now) through odin and stuff. After all that, it was still lagging, freezing, and restarting etc... Ran it through safe mode and the only problem in safe mode is that the lag is gone, but the restart is still there. Running in safe mode, if I would turn the screen off and back on to unlock my phone, there would be like 40% chance that it would restart after unlocking the phone and the phone would just restart normally. Rarely, whenever my phone would attempt to restart.. I would get a "Could not boot normally" message along with couples codes below and the image of android guy. Then I would have to take my battery out and attempt to restart the phone once again.. I've wiped the cache and everything in recovery mode, nothing helps at all. Also, the phone is in perfect condition. Hasn't been dropped, cracked, no water damage, or anything like that.
This place is my only hope to fix my phone before I will go out to buy another phone from the carrier.

Well I already got rid of my note 4 unfortunately before anyone could help me here so I had to upgrade my phone to note 5 and return note 4. While I still had my note 4, I realized something weird. While the phone was lagging and crashing etc.. When I had it plugged in for charge it would work perfectly fine. No lag, it wouldn't freeze up or restart (had it running perfect for 7 hours). It was like my phone was brand new again. As soon as I unplugged it from the charger, few minutes in and it was back to restarting and all that. I never knew why it did that.
Anyone know why this mightve happened?

Might be the battery though

I thought that too. I tried my brothers note 4 battery for awhile and it worked for a little bit and then it started doing the same thing even on his battery. Shrugs.

In the COH update iteration there is an annoying bug that affect fingerprint.
The bug causing the phone to restart, lagging & closing all apps randomly when the fingerprint is set.
May be this one is also the same.
Try to disable all fingerprint related settings.

I never used finger print scanning on my Note 4. Always disabled.
