Phone restarting itself?

Has this happened to anyone? Just started happening today for me after I flashed factory ROM for the second time. Do you think it's the device or software issue?

My phone has rebooted twice and that is the only widget I'm using. I'm on rooted stock rom. A few other people said it was that app that caused the Nexus 7 to reboot so I'm guessing it's the same reason for our phone. I haven't used the widget for 3 days now and no rebooting since.

Overheating?
I had been watching Netfilx on my Nexus 4 using mobile data and my phone just restarted by itself. I was also charging it at the time, after it reset, I checked the temp. and it was at 102 f. I'm not sure why this happened, but it is the second time while I was using Netfilx, I didn't check the temp the first time... I'm starting to get worried, is it just me? Is it just because the phone is doing too much? Am I alone in this?

I have bought a 32gb nexus 7 from best buy in canada and wondering is it all the same ? Just don't want to end up whit a brick or anything
First 4 hours of use impression : it came preloaded whit 4.1.1 its snappy if you ask me but sometimes in application we can see some small lag but great tablet for its price !

With every electronic gadget using Lithium-ion batteries nowadays, it doesn't really matter how/when you charge it.
Some would argue to make sure to allow a full discharge from a full charge from a battery calibration point of view, so the battery meter is more accurate. It wouldn't affect the health of the battery itself either way.
Things like memory effect doesn't apply to lithium-ion. How often you charge it and how much you charge it (full or partial charge etc.) doesn't affect it much either. The only 2 things that can potential kill a lithium-ion is high temperature and letting it discharge far too low to the point that it cannot be charged up again. Note that all electronic devices will power off way before it even reaches this threshold.

Read this in a different thread when i was unboxing my nexus 7, i let mine sit for a while on the charger before i turned it on, but it came charged already. So far i have not let my nexus drain to 0% and the battery life on it is great, it can go for a entire day.

I too just got one. May be came out of the box with 4.2. After I signed in I checked for an update manually, and it immediately upgraded to 4.2.1. I then rooted immediately! Battery has been impressive so far.

No luck for me i guess it shows that there is an update it downloads it and boot into recovery attempts to install but then an android robot laying down whit his chest open and a red triangle appears ?

Sounds like it may be a corrupt download. Unless you plan to remain on the stock ROM just unlock/root it and then install what ever ROM you like.

If I keep using it for like 30 minutes (hard use) it reboot... How can I do a factory reset? Maybe that fix it...
PS: I notice when reboot it get really hot! I don't know if that is part of the problem..

You said your phone shuts off after hard use, and you said it is really hot when it shuts down. This sounds like a hardware problem. When the processor gets too hot, the device kills power to protect it from frying. Almost every computer has a similar last-resort power-off feature to protect its hardware.
Now the real question: What is making the device overheat? Most likely this is a hardware problem, but there is a remote possibility that the problem could be a rouge app.
A factory reset will remove the apps you installed. If there is an app running an infinite loop in the background, a factory reset might fix the problem. (I remember you said you are running stock without root, so there are no firmware issues. The only possible software issues are with your apps.)
I am sorry to say that you might have a defective board.

But why start doing that after a month of using it? The only new I did was using the maps app for more than 4hours... A friend toll me to clear cache on map apps...

If the problem really is hardware, it was a defect that made it past quality control. It's the same reason why a new hard drive might fail after a week of usage--infant mortality. Infant mortality is quite rare, but it does happen nevertheless.
Fortunately, Google's replacement procedure is quite nice compared to most other companies. If Google sends you a replacement, you can keep your existing phone until the replacement arrives. This way, you are not left without a phone temporarily.

Update! Did a factory reset and root it and it's good now! Looks like an app was causing the rebooting... Thanks for the help!

Nexus 7 shutting down in idle state due to battery drain!

My nexus 7 was fully charged and I put it in the rack in the night. Next morning it shut down completely. When I switched it on, it showed battery 0% says 0% the same c thing happened today as well. Its a new device. Any idea??

Some app or service is draining your battery. Get BetterBatteryStats to narrow it down.

Like someone said before it's a rogue app and the only way your going to get the battery drain issue to go away is to figure out which app is doing it and then get rid of it.

I think the best solution for you is to factory reset or re-install android on your device once.
It will be easier than finding out where is the problem. as screen snap shows most of the battery is drained by "android OS".
It was just my opinion you can take it if you want.
My battery usage. Even though my screen on time was only about 2 hrs most of the battery was drained by the screen. So there music be something very wrong in your case.
I don't know about android virus but that might be an option.

Gonna follow along and disable my daydream as well since I'm having the same problem you are with it actually draining while on the charger (Stock ROM, Franco Kernel, OEM wall wart with gold tipped USB cable). Tis quite annoying to have to either keep the screen off or power down completely in order for this bad boy to charge...

Rootchecker and returning to stock

Hey guys I'm on an AT&T D800... since Monday afternoon my phone had been unusable... it got extremely hot both front and back near the mid to top of the phone... and was just chewing through battery 31% in 15 minutes... so I powered down and left it numerous times on different stock based rooms and still no luck it would just overheat till it shutdown or battery died if I didn't turn it off... I managed to get it charged enough to restore my stock backup, unroot, and put the stock recovery back on and then did 2 factory resets with still no change... so I called at&t and they sent out a warranty replacement which will be here tomorrow.. so my question is do any of these return to stock methods actually clear rootchecker? That's my only worry that they'll see that and nail me the retail price of the phone... I didn't use a custom kernel just the roms...
I see conflicting stories from people saying yes it does it clear rootchecker and others saying no.. I would just try but I don't have WiFi so I don't burn up my months data just to find out it didn't work.
The phone seems to be working fine since I powered it up 2 hours ago but I'm worried about any residual/repeat issues or decreased lifespan of phone from the overheating issues
Thanks in advance!

Flashing a Stock .kdz works completely. Perhaps you should read this sticky: http://forum.xda-developers.com/showthread.php?t=2432476

Thanks I've read that one before but I've also read other threads that say it still shows rooted when booted into download mode even after doing this reflashing

Did you check to see why the battery was being depleted so fast? I am willing to bet the phone itself was fine, but some app was utilizing the entire CPU, which would heat the phone up and kill the battery quickly.
Which means it's entirely possible you'll have that issue with the new one as well.

Yeah but after 2 factory reset there were only unused factory installed apps
