So I got my nexus 5 before not even a week ago and from the first day I got some random reboots that are really just random without a pattern, app or something to do them, they are just random. But I didn't care mostly because I wanted to wait a bit before I began customizing it. After I waited a little bit for the OTA update to come to my nexus 5 I thought to myself what could happen if I unlock the bootloader and root it so I could update my rom. So I did that and after a little more tweaking I found a nice merge of 2 kernels (franco & one that has DT2W) so I thought why not. I installed it, but the same night after 4-5 hours the phone began bootlooping to the point that I really couldn't even load TWRP. I fixed it by flashing default android and kernel and after that I updated it to 4.4.1 and rooted it without a problem. The random reboots kept occurring though Today I thought that I would backup my rom so I could try some other kernel, but I cannot literally be in twrp more than 10 seconds. After I begin installing a zip or backup or whatever else the device reboots for no apparent reason. I need help because it reboots every 2 minutes when I am talking, Thanks for your support ! Only fix that I have seen is that I flash default kit kat through the Nexus Root Toolkit.
I updated my Nexus 5 today, using the official firmware + fastboot to flash all but the user parition.
Everythink worked fine, applications get updated, phone is booting and running.
But the device is getting hot, even 15 minutes after flashing. Anyone else monitored this behavior ?

Do you run Greenify? The stable version was causing that on mine. It doesn't work with Lollipop. There's a beta version that seems to work fine.
After a clean shutdown and restart, the warming has gone.
I guess something hung there in background and caused CPU load.
The title pretty much says it all , phone crashes all of a sudden , but I've had 5.0.1 for however long Its been released and today my phone randomly started crashing . Wondering what could've caused it . I'm stock rooted and running twrp.
You have root access and a custom recovery so it could be one of many possibilities. Reflash system.img.
Did you undervolt it?
I work with a couple guys that have bone stock Nexus 5 with lolipop. Both are non-rooted and locked, however one has the random soft reboot problems. It mostly happens after phone calls. The other one doesn't have a single issue.
Good afternoon gents!
This is the first time I post on this forum so I apologize in advance if I am not going to provide all the details regarding my problem. I'll try to be as explicit I can with my issue.
A couple of weeks ago I bought a LG Nexus 5, second hand. After one day of use the device started to randomly reboot. The odd thing is that the reboots seem to be "soft". After the device restarts there is no data loss, even the recent apps are still there. The reboots are as random as I can get, when browsing with Chrome, checking emails, or playing a game.
I tried several fixes, including costum kernels, costum ROMs and so. The problem persisted with the official KitKat 4.4.4 and Lollipop 5.0, 5.0.1 and 5.1.
Currently I am running stock Lollipop 5.1 with stock kernel and TWRP 2.8.5.2 recovery and the device is rooted.
Below I attached a screenshot with the device's current configuration and a text file with the kmsg log from the last reboot.
Faulty power button.
Reboot phone into bootloader/fastboot.
If it random reboots in the bootloader too, it's likely the power button.
Nope, I already tested this. The device reboots during use, either heavy or simply browsing the menu.

I noticed this in your Log
"<6>[ 0.514020] [email protected]: Power-off reason: Triggered from UVLO (Under Voltage Lock Out)"
Just curious, Are you undervolting?
I don't know exactly what undevolting implies. Could you give me more details please?

Lowering the voltage the CPU runs at, at certain frequencies.
I understand. No, I did no change any of the voltages. In that log that I posted up there the device is rooted and has TWRP 2.8.5.2 with stock lollipop 5.1 and stock kernel. Later yesterday evening i installed xtrasmooth rom with franco kernel and the phone only restarted in Here Maps from Nokia. I'll run more tests, but from this I draw the conclusion that it is a software problem, not a hardware one. Unfortunately I can't RMA the phone. Do you lads have any other opinions?

Try posting another log if it happens again.
I'm back with the latest ksmg log here. I searched for fixes all over the internet and nothing seemed to fix the problem. Restarts also occur in safe mode. Below is the latest last_kmsg.

This log shows a kernel panic.
My n5 reboot today without any reason
That was the only thing I understood from the log too. Do you have any idea what's the reason for these kernel panics and a possible way to fix them?
I experienced today three more random reboots. I attached down the logs. As an unexperienced users point of view all of them are produced by a "Unable to handle kernel paging request at virtual address" . Could anyone throw a look on them and give me a possible reason for these reboots and a possible fix? Thank you in advance

Same problem as this guy
http://forum.xda-developers.com/showpost.php?p=59551481&postcount=8615
having the same problem. i'm running 5.1, but dont know if it's caused by that, cause i just got this phone as a refurbished one from google.
Good day lads!
I tried since the last post more possible fixes, and the only thing that showed some resuslt was downgrading to 4.4 bu the device still resarts exactly once a day. I am going to switch to another phone.

If you just recieved a new device and you have the possibility to RMA it, I suggest doing it. I went as far as page 30 on google searching possbile fixes and came up with no valid result.
Hi, I've got some random reboots after upgrading on stock Lollipop 5.1 on my Nexus 5.
I've used Android 5.0.1 without any reboots or problem, but after upgrading on 5.1 I'm facing many random reboots when I switch from an app (like a game or Hangouts) using Recents or Home button from NavBar (it also happens randomly when I'm using my phone, like writing a message on Hangouts).
The reboots I'm talking about are not "soft" but "hard", because bootloader's logo (Google) appears and restarts my phone, so it is caused by Kernel Panic (as you'll see in my last_kmsg) and they occured on both stock and custom rom.
Here is a "last_kmsg" when it occured on stock Lollipop 5.1: http://pastebin.com/80dDgzae (attached too).

Flashed Android 5.0.1 and no random reboots (as I also said when i wrote my first post).
I don't know if the "question" is clear, but can you help me reading the "last_kmsg" which I attached in first post? Thanks
Same exact thing happening to me also.

The same is happening to me. And it looks like a hardware problem cuz when the phone reboots it keeping reboot until I keep pressing the power button while boots.
I have a bad experience about it. In my Nexus S when updates to Jelly Bean the same occurs until phone suddenly die. (I live in Brazil so, guess what? I have now a wonderful paper weight)
No luck with 5.1.1
You guys found any fix?
I was waiting for 5.1.1 update from Google (5.1.1 code is already available on AOSP and I tested it on Chroma), but unfortunately it didn't solve this problem: it keeps rebooting after a long daytime doing the same things I already wrote in first post. I'll wait for factory Google factory images, but I'm pretty sure it won't fix this.
P.S.: I tested Chroma on 5.0.2 bootloader and modem.
Anyone can read "last_kmg" I posted in first post? Any other has the same trouble?

I just flashed ElementalX kernel but no luck, random reboot happened on 5.1.1 too. By the way it was quite obvious because it happened already on 5.1 Google's factory image (stock kernel so)..
I have exactly the same issue with nexus 5 since upgrading to 5.1.0.
I went back to 5.0.1, which solved it for a few days, but now this happens with 5.0.1 as well.
also, before random reboots happen, the power button becomes extra sensitive, so one keypress causes the screen to turn on and off again, or to display the shutdown menu.
this does not happen when the phone is stable.
Hey guys i have the exactly same problem since i upgraded to 5.1.1 i am non-rooted please need help

Same here.
LG Nexus 5 - Lollipop 5.1.1 LMY48B
Unlocked bootloader;
Rooted;
ClockWorkmod 6.0.4.5 (not flashed - just boot on image when used);
Wipe factory reset (in cwm). Flashed 5.1.1 image files (boot, radio, bootloader, system and cache).
Random reboots, and sometimes with apps optimizing.
I have the same problem with N5 since upgrading to 5.1.1 - never had any problems before. Doing it several times an hour now. Trying a cache clean next, after I wait for the optimising apps to finish yet again!
Hi all,
I had the same problem. Everything stock, up to datę, no root. Phone was rebooting itself several times in a row.
Right now it seems that problem dissapeared. Reboots in my case was caused probably by application Autoguard Dash Cam Blackbox. After removal no reboots for 2 months and no memory leak.
cleared cache and it happened again within a minute...
Does seem to be linked to the power button
There's a long thread about this issue over at Google Groups. It's affecting a lot of users and not just Nexus 5 users. Some in the thread are 4 and 7 users having the same issue. Some have replaced the battery and it has resolved the issue, at least temporarily. Others, like myself, saw success in rooting and replacing the kernel or using a new ROM. Users who have downgraded to Kit Kat report the issue goes away, so despite the power button triggers, it seems to be a software issue. Anyone have any insight? It's getting feisty in Groups thread.

I have N5 kit kat 4.4.2 in Chrome watching videos randoms reboot its happens
This is happening to my fiance's N5. It happens when she's using it and also when it's not being used. When it reboots, it optimizes the apps and says the battery is at 0 when it was a full charge. Only way to turn it back on is to connect it to a charger. Frustrating.
FYI the update to 6.0 did not solve the restart problem. It's either hardware related, app related or a bug that's still in the OS.
I'm selling my Nexus because of this, has been happening for a few months now.
It's not software related, it has to do with the actual power button. Some people had success changing it out, soldering it etc., but I don't have that time or knowledge.
Google wouldn't help, as I'm out of warranty. So I guess it's goodbye Nexus. Really unfortunate given that the phone works fine, it's just a quality issue.. will have to re-evaluate buying another Nexus in the future.
