"Data Usage" freezing and keeping the phone awake

I have a Galaxy Nexus GSM phone running Android 4.0.2. Occasionally I am noticing the following behavior:
The Data Usage section in the Settings when clicked freezes, becomes completely unresponsive and the whole Settings app needs to be "killed" using the "Recent apps" in order to function again. When I click on Data Usage again, though, the Settings app freezes again.
I noticed that when this happens the phone's wake time becomes significantly higher. The battery stats show that it is almost constantly awake even if the screen has been off for hours. Going through the application list in the Battery stats shows that "Android system" is keeping the phone awake.
I found a temporary solution to be the following - connect to a wifi network, open the browser and browse through 1-2 pages, then turn the wifi off again. This makes the Data Usage section become responsive again and the Awake time becomes significantly lower.
However, the bug comes back again in a few hours - usually in about 8-12 to 24 hours or so (I have not found any pattern and the timeframe varies greatly).
I did a factory reset and it helped for 2-3 days and then the issue started appearing again.
I have seen many threads describing battery issues but not with this exact pattern and I decided to share and see if anyone else is experiencing it?

Upping the thread a little...

I also have experience this. Yesterday I restarted my phone on a place where I have no known wifi networks and I cannot access the Data usage menu and my attempt freezes the settings window. My nexus keep awake all the time. I fixed it later by connecting to to wifi.
I experienced this before and in situation where you start the phone with wifi off, and again fixed it when you turn it on and connect to a network.

Were you able to find a more permanent solution, apart from connecting to a wifi temporarily? This solution woks only for a little time for me and then the problem re-appears.

Personally, since the hardware itself works fine, I'd backup everything and flash the stock image from Google. If you're not comfortable with that, then have your phone swapped out under warranty. This sounds like a bad flash (before reflashing to get 4.0.4, my data viewer would miss entire apps and occasionally reset itself mid-cycle, defeating its entire purpose), so those are really your only two options.
You could also see if there's a random app causing problems, but I doubt that's the issue here.

Thank you for your suggestions. I have recently made a factory reset and the problem was still there, so I believe it is not caused by a 3rd patry app.
I am willing to try flashing the Google stock image. I believe I can find more details how this is done but do you think that I will be able to do it if I am not rooted?

1) Select your model of phone (I'm assuming GSM/HSPA since you're from Europe)
2) Click the "Drivers" button and follow all prompts to download and install the needed PC drivers.
3) (Optional) Click Backup Apps + Data. Follow on-screen instructions to save all of your apps to your PC, because we will be wiping your phone in the next step. Do NOT save system apps and settings, since you have a bad flash. If you have anything saved to the virtual SD card, copy it off now as well.
4) Put your phone into fastboot mode (turn off, then hold Volume + and - at the same time and then press powe button). Click "Unlock" button on tollkit and follow all prompts. This will unlock your bootloader. This will also erase everything on your phone. Your phone will reboot when it's done. Turn it back off and boot back into fastboot.
5) Click "Flash Stock and Unroot" on toolkit. This will download the proper files from Google and flash your phone. Your phone will be factory-new. It will not be rooted.
6) (Optional) You can also click "OEM Lock" button if you want to relock your bootloader. This really doesn't make a difference if you're planning to stay on stock ROM. Personally, I'd keep it unlocked unless you plan on exchanging the phone.
7) Click Restore Apps + Data if you backed up your apps from before.

The steps that you provided worked very well (I hit a few bumps with the drivers but managed to work them out). I re-flashed the stock image and everything seems to be OK so far. I will be checking if the problem with the Data Monitor is resolved and will report here.
Thanks so much for your help!

Something similar is happening on my LTE Galaxy Nexus in the Settings Menu. After a while when I click 'More' in the Settings menu the Settings app freezes and must be closed, otherwise the phone is inoperable.
What's scary is that it started happening AFTER I flashed the recovery image, because I enabled encryption while running a custom ROM, so the only way out was to flash the recovery images from scratch. Perhaps something went wonky during the flashing process, so I am going to follow the steps listed in a later thread.

[Q] Rooted 4.3 OTA soft-bricked, wouldn't load any apps

So basically I did this:
http://forum.xda-developers.com/showthread.php?t=2538991
But unfortunately, I hadn't realized that the mobile hotspot was sealed up in that update. So I looked it up, and saw that someone had recommended this:
http://forum.xda-developers.com/showthread.php?p=48326067
So I went into TWRP and installed it. But that didn't work. When I booted back up EVERY app was crashing immediately except the stock Samsung apps (Messaging, Email, etc.). I tried to reverse it with the original framework-res.apk but when I did, the phone would get stuck at the AT&T logo (which was silent). I went back and forth a few times (when I applied that tethering mod, the phone would boot; when I tried to reverse it, it wouldn't), then did a factory reset in TWRP. After that, the phone booted, but the Setup Wizard would crash. So I did a Nandroid restore in TWRP and now the phone hangs at the AT&T logo no matter what I do.
My question is, what can I do now? I have a replacement device coming through warranty just in case, but it would be much better to just fix this one. However, I want to be certain and not HARD brick the phone...

I have never been able to restore a stock 4.3 nandroid without everything crashing. I have always had to go back into recovery and wipe data/factory reset and wipe cache and dalvik cache then reboot and go through the whole setup process again. If that doesn't work you could try installing the stock debloat ROM from this thread. That's what I am running and it works great. http://forum.xda-developers.com/showthread.php?t=2540998

if you can get back to twrp , clear everything then flash the official correct file that yu want then see if that works...restore your apps/data after a clean refresh for your phone
remember panicking and being paranoid with flashing/rooting is not a a good idea, always rethink what you did wrong, let the phone cool down, research know what you re doing then fix it
dont rush, cuz rushing leads to bricks (learned from experience from day 1 with root)

How'd you do that? Just the regular factory reset? Cause the setup wizard wouldn't even run after that.

Hit the power button to make the screen go to sleep. Hit the power button again to wake it up. Nothing should be crashing while you are on the lock screen so just hold the power button until the power menu appears and select power off. Once it powers off hold the volume up, home button and power button until you see the blue words in the upper left corner of the screen I believe it says loading recovery. Release the power button but continue holding the other 2 buttons until recovery loads. Now wipe data, cache and under advanced wipe dalvik cache. Reboot and everything should quit crashing but you will have to setup your account and apps again. That is the only way that I can get stock touchwiz 4.3 nandroids to work.

[Q] downgrade to jellybean

anyone know how to downgrade from kitkat to jellybean?
kitkat is bull****. no notification light, now screen doesn't even light up when I recieve a text.
thanks.

1. Open flashtool
2. Flash jelly bean firmware

flashtool is a rar. do I use it on PC?

Flashtool is a program for Windows. You can download it from here: http://www.flashtool.net/index.php
You can find jelly bean firmwares (ftf) in the sticky thread in General section.

If you download the latest version it's an executable so you don't need to decompress it with winrar.

I've got kitkat myself and I have to say it works 100%, I have no bugs whatsoever, battery life excellent. I wiped my phone completely before upgrading to KitKat maybe that's the difference between bugs and no bugs.

Since kitkat, my notification light stopped working, and now my screen does not light up when I receive a message... bullcrap.
I downloaded emma flashtool, and signed up, but no authentication email yet (hours ago) and you can't use it without that.

My one still works and my screen does light up when I receive a message. If you're going to downgrade you might as well reset your phone. I'm sure that'll solve your problems.
Of course it's up to you.

Yeah it will wipe absolutely everything. But so will a downgrade to Jelly Bean.
Files on your SD card will remain but I would take it out before you reset it just in case.
Contacts should be sync'd to your google account?
The only thing I've needed to do after a hard reset is download my apps again. You can backup your SMS and Call log using an app on the playstore called Super Backup.
To do a hard reset:
Settings > Backup & reset > Factory data reset.
A factory reset will just wipe all data on the ROM you're on. If you're on Kitkat and you do a factory reset you will remain on KitKat but all data will be removed (apart from factory data/apps). If you're on JellyBean and you do a factory reset you will remain on JellyBean but all user data will be wiped (factory data/apps will remain).

[Q] Lollipop Battery Life. Help?

I'm sure a lot of topics have discussed the battery life of LG G3 on Lollipop. Here I'm trying to figure out if I did something wrong.
I own a D855 (Asian) with stock ROM. I upgraded to Lollipop V20B-SEA-xx in January through LG PC Suite. I found out that the battery life was a lot worse than KK, so I did a factory reset like many suggested. Before the factory reset, I use the backup menu in the phone and backed up everything. I duly restored everything after the factory reset. The battery life remained the same.
2 days ago I upgraded to V20C-SEA-xx through the PC Suite. I got stuck in a bootloop after the update, so I did a hard reset (which returned my G3 to Kitkat 4.4.2). I downloaded the update once again and my phone booted. However the notification bar and home buttons are missing. I tried doing a factory reset using the menu in settings, but it did nothing, so I did another hard reset. This time it booted normally, and I proceed to restore my data/settings/etc through the restore function in settings.
With V20C, battery life is even worse than V20B. I read that a lot of people get better battery life after a factory reset on Lollipop, but I'm not that lucky.
So I was wondering whether it has something to do with the backup and restore that I did? I was thinking of doing another hard reset and setup my phone MANUALLY this time. What do you guys think?

I just upgraded to 20H and battery issues still persist. On 20F I calibrated my phone and it helped a bit. Lg has to do something about it. I hate hard resetting my phone after every software update.

My battery was sh*tty too after 20H, but after reset its perfect. Last the whole day with heavy using

Yeah, "somehow".
First you delete all bad and broken settings, which led to apps misbehaving and battery drainage, then you restore them.
Seriously, try to set up phone from scratch, without restoring anything from google account or whatever.

Also, you may not want to add google account in setup screen. There was a case in which pulling wifi settings from google resulted in inability to search for wifi networks. Same thing may have happened to your account - some settings got broken, and they're synching back after every hardreset.

soft reset is done by factory data reset option from settings--> backup&reset
hard reset is done by turning your phone off, then holding the vol down+power button together. After the LG logo appeared, release both keys and then hold them again immediately. It will then ask you if you want to do a factory reset. Use the power button to select.

exact same problem
I encountered the exact same problem while upgrading from v20b to v20c through lg pc suite... I immediately connected my phone to lg mobile support tool,which then updated my phone to v20c ... I noticed that lg mobile support tool was upgrading my phone from kitkat(while my phone was in boot loop)... My data was not lost ...

[Q] Help ! can't find the problem with my LG G3...

Help ! I own an LG G3 and randomly had a problem with the stock messaging app as it was failing and crashing, so then I decided to reboot my phone but as it rebooted, it was still the same except it had a stock background, no knock code, and my home + recent apps buttons do not function at all but show touch feedback... also when I long press my recent apps button it brings up the settings tab which it should do, which is odd, also my return/back button still works fine. I switched my background to my original one and enabled knock code again, then tried rebooting, hot booting, and powering off and on the phone but nothing worked it even reset my background again to stock and disabled my knock code. I can answer any questions other questions, Any help would be appreciated, Thank You !
Edit: Notifications do not show and the stock camera shortcut ( Hold volume down ) stopped working.

I'd probably try a factory reset if you haven't already. Also list your current software version and carrier info., which might be helpful to us in helping you.

Well, if you are rooted, you might try going into your custom recovery and wiping cache and dalvik-cache.
Since you suspect the messaging app, maybe wipe the data for that one as well? You'd lose all your messages, of course.

I don't have a custom recovery, whoops. The messaging app was fixed after the first reboot, which is when my phone booted that all the other problems occurred. Thinking of just backing everything up and factory resetting, although I wonder if I back up my phone and reset it then load my back up would the problem persist ? as maybe it stems off the soft/firmware, feel like this is the problem since the buttons show touch feedback but do not work.

Glad you seem to have it resolved.
BTW, a couple of notes and suggestions on best practices:
1. If you root and intend in any way on using the elevated permissions to modify your system, you should install a custom recovery, such as TWRP. This will allow you to backup your entire system at any time and restore in the event of an oooops! event.
2. If/when you have a custom recovery:
NEVER accept an OTA (over the air) update. It will bork your phone.
NEVER perform a factory reset from a stock ROM. It will bork your phone.​
