Phone rebooting - Nexus 5 Q&A, Help & Troubleshooting

Hi, twice today my phone rebooted. Once on a call and when it booted back up after I put phone on charge and left it for 5 minutes and it rebooted again. My phone is all stock on ART runtime. Any ideas? It did happen few weeks ago too while on a call.
Thanks.

without any kind of logs, nor a last_kmsg, it is just a guess why your phone rebooted. since this guess is as good as any other guess, i say that your phone rebooted from fear of dinosaurs.

How can I get the logs that haven't been eaten by the dinosaurs yet?

Disable ART it is experimental right now. But with out logs finding out why is a guessing game and an uneducated one at that.

do you have root? you can run a last_kmsg after a reboot. the device automatically saves this after a reboot that you didnt do yourself. this will show why your device rebooted.

"Hanging Up" Bug.

Just activated my nexus 5 on sprint.
Just after I make or receive a call, my nexus becomes useless and I cannot do anything until I restart the phone. I have no data and cannot make or receive calls. When I try to make a call, it says I'm already in a call and asks me if I'd like to use touch tone keypad, return to call in progress or add call.
Anybody else have this weird issue? After I make or receive a phone call, my nexus is virtually useless till I restart the phone. No matter what I do after a call, if I hover anything over the front right sensor, the screen goes black. The phone must think I'm still "in a call".
If it goes limp, there's medication for that.
Lol really though. How many times has this happened?

Have you tried factory reset yet?

I heard it's a little buggy after just activating but the phone settles down after a bit

[Q] How do I prevent USB file access at lockscreen?

In previous versions of Android, when I plugged my Nexus 5 into my computer, if it were at the lockscreen I had to unlock it before it would show me the files on the sdcard. Now, though, running 4.4.2, I notice I no longer have to do that. I can just plug it in and at the lockscreen go to my files. While convenient, especially for transferring large files, I'd rather a thief not be able to do this. I can't find any setting for it though. Any ideas?
Have you got a pin code or just swipe?

Also on my N7 2012 w/ 4.4.2, also using pattern, I can't access the files via USB until I unlock. Same pattern too.
This is what mine does on both windows and linux.
Plug in locked .. device shows but is blank. Upon unlock, directories become visible.
If I lock whilst already connected, connectivity is not lost.
Not sure why yours acts differently. Would be pointless having a lock if you could still get data
There is no setting for this. Maybe you need to wipe ? If unrooted, backup with helium

+1. I just tested mine on 4.4 and 4.4.2 and have the same behavior. Pin lock.
And this is exactly what my n7 does. But my n5 doesn't. I can immediately access my files.
Franco kernel but was even happening on stock. In fact thinking back my n5 has always done this since I got it a month ago.

There probably was a time when it worked. Probably should do some testing with a full wipe. Maybe its an app
Sent from my Nexus 5 using Tapatalk
With mine on 4.4.2 it locks device access until pattern lock is put in. Perfect. It sounds like you have an app interfering or need to do a reset.
Ugh. Even with titanium backup I hate doing wipes. But I suppose if it fixes it then it comes back when I restore then I'd know it's an app. I'd hoped this was a known issue.
Take a nandroid. If wipe doesn't fix it at least you can full restore

Nexus 5 lags after turning on art

Hi guys... one of my friends just bought a nexus 5 and he turned on Art and then the phone rebooted normally. After the reboot, it was laggy so he turned back to dalvik hoping that this would make the phone fast as new, but it didn't happen and the phone is laggy right now... How can he repair it? Thanks in advance
EDIT: he selected again dalvik and then the phone were again fast
Should switch to art after a factory reset. Works great. Better battery and performance

art isnt meant to be used yet, its an experimental feature thats only in kit kat so that devs can develop for it. People need to stop reporting/complaining about ART bugs and wait for the finished product
It is located in the
"Developer Options" for a reason.

[Q] Youtube keeps running

Hey guys
First of all I want to me clear that my Nexus is stock, never been modded.
The issue is that youtube seems to be running in the background, even when I close it. Every night before bedtime I watch some youtube and i noticed that in the morning the app is still running. And if I don't reboot my Nexus i'll just keep running all day leaving me with a dead battery in 6houres..
I was wondering if anyone else had this issue? And so, what did you do with it?
Don't feel like wiping my entire Nexus so some advice could be usefull, if nothing helps i'll just keep rebooting every morning.
Actually in 'running' or in 'cached'?

Running, my Phone also gets warm after just sitting for 6 hours on my desk.
Wierd thing is that it doens't add up with the info i see in the battery info screen. There it says it ran for 2h, while my Phone was off the charger for 6-7h. That's why I don't understand my issue. I tried googeling my problem but all I seem to find nothing usefull.

wont activate?

anyone else having this?
it has been trying to activate for 6 hours now, just keeps re-trying
probably just so many are trying to activate right now but i have bought release day phones the last few years in a row and never had this
Mine did that all day. Once I got home and left it alone to charge for a bit, it went through a few boots and finished. I wouldn't worry about it.

They actually sent me home from the store before I noticed it. A couple of reboots today fixed it, but then it just proceeded to download all the Sprint bloatware and compleatly hosed my home screen setup. After that the "activation not complete" notice went away.
