Yes but most everyones problem is your just taking the update. The same update when flashed to clean wiped tab will most times resolve the fc issues that pop up from a update.

Phone rebooted twice today

I'm wondering why this is happening, it has done it before but 2 times within 3 hours. I'm beginning to worry... Any ideas?
Oddly enough it seems to do it right when I pick it up to use it.

I had mine reboot on me today as well, it's the stock rom with root. I didn't pick it up. It happened while I was tethered using the free Wireless Tether App and the phone was asleep.
Yea, I don't even have root.. it has done it 2 more times since my first post.

one of my co-workers has been having the same issue. (completely stock as well). Mine has rebooted a handful of times, at least once that was possibly at the exact time as my co-worker's. He's called in enough that they are offering to replace the phone.
Me Too
My phone has been rebooting more and more recently. I suspect it is very poor signal causing the phone to work too hard, triggering a reboot. My will get to 109 degrees for no particular reason, and then start rebooting.
My warranty replacement (refurb) is expected today.

Only have access to 50% of my battery.

For the last week my nexus 7 has been completely dying around 50% battery. If its in sleep mode when it hits that % then it won't turn on, if I'm using it when I hit that % I get a weird flicker then it shuts off. This just seems extremely strange that all of a sudden only half my battery works. A long with only having half my battery to work with, it seems like the tablet has been charging a lot slower then normal. I use to be able to work it down all the time and usually didn't charge it until 5%-10%
Anyone else ever have this issue? I contacted Asus and there only solution right now was a factory reset. I cant see how that could fix the issue at all.

are you rooted? what type of kernel are you using?
I have read that sometimes a factory reset refreshes the battery settings. Is your device rooted or rommed out?

That happened to one of my friends S2's. Factory reset it. It worked for my friend. My N7 also charged really slow. I just changed the ROM. It is the same thing as a factory reset because you do one when you change your ROM.

As said before, try a factory reset !
If no luck there
Try download a battery calibration app to see if its mis-calibrated etc

Sounds like it is time for a call to Sprint and make them fix it. What I would do if not rooted.

If your network was unstable you wouldnt be able to get any signal at all but it wouldnt make your phone reboot. Have you tried factory reseting your phone??

Whatever is going on its in the kernel i flashed the MDB kernel and everything is working perfectly the only problem im having know is my phone says custom software.

Dude you ain't the only one. The MF9 update has been a major pain the @$$ for a lottt of people. I wonder if Sprint is working on a new update. Hopefully push it out before the end of September. Although I am really liking MF9, I am probably in the minority. My device is smooth as hell and great battery life. Just yesterday I went 20hrs with 3hrs of on screen time!
Im having a similar problem. Random reboots when data is connected. I first thought it was the connection in my area that was causing the problem to (NV just started in Cleveland) until I encountered reboots while on WiFi. It doesn't matter what app I'm using as long is it uses the internet connection my phone may freeze vibrate two to three times then reboot. I even reapplied the MF9 update and the same problem exist.
I'm completely stock!
Thank You Based God!

We must be lucky. I keep reading about all these issues, but MF9 had been awesome for me. Not a single problem, and definitely much better than MDL.

+1 on that. Been on MF9 stock rooted since I got the phone a couple weeks ago and all has been well. I wonder if it could be a hardware issue mixed with something thats in the MF9 update. Sound crazy to anyone?

Check your source for the MF9 kernel you have and try downloading and installing a different one.

[Q] Dies at ~70% charge

My nexus 10 is dying with displayed charge at or around 70%. I had lost the tablet and it was dead for months. Idk if that is relevant or not. It did take a full charge a few times after finding the tablet before the above stated issue occurred. The charger I'm using should be in good shape as it charges my Galaxy S4 w/o issue. Running CM 10.1.3 (Stable).
Thoughts? Thanks in advance.
Update: now the device is dying while showing charge level in the high 90% mark. Device now dies mid-boot even plugged in. Before it would stay on so long as I kept it plugged in. It will stay on if I go into cwm. That's the curious part.
Sent from my SGH-I337 using XDA Premium HD app
After doing some research I'm going to guess calibration to be the issue. What to do if calibration is so out of wack it thinks its charged when it's dead?
Update: I ran calibration after I managed to get it to 100%. A few minutes later it died. Curiously I put my tablet in recovery mode and it has stayed on for at least an hour now. However when I try to boot into CM it dies. Every retry it dies a little sooner in boot.
Maybe you could go back to stock via fastboot. If that doesnt work I think tour battery is dead.
Sent from my Galaxy Nexus using XDA Premium HD app
Actually I've been letting it sit idle in recovery mode. Its had at least 4 hours to drain now. Haven't been able to kill it yet so I am extra confused. I read the charge with an app and it was at 4400. The tablet is perfectly happy in recovery. I wiped my system partition and reflashed CM. This seemed to have an affect to a degree. Once the dalvik cache was rebuilt the tablet died again and went back to the odd behavior I mentioned. I would prefer to not return to stock unless it is absolutely necessary. I will if I have to but I would like to see if anyone else has seen this issue or has an idea on how to TS it as is.
For the Android junkie this would be a fun issue to trace down. I simply don't have the education. I just created my developer console account and am going through the documentation to create my first app. Clearly outside of Google Fu I'm relatively useless.

Try wiping the battery stats from recovery, if yours lets you.
Have you tried wiping/factory reset and starting with a clean install? As part of all the rebooting, you may have corrupt file(s).

I think in going to have to. I've proved the battery is charged and CWM knows it. I'd like to do a titanium backup to preserve my game data but I don't see how if the darn thing dies mid-boot. May have to bite the bullet on this one

It didn't so I just wiped the whole /system partition (I believe that's where the battery bin exists) and flashed CM back. No good.

Flashed full factory image
I used the image found here to completely wipe and reset all partitions and make the thing like it just came out of the box with no trace of mods left (that I'm aware of). It happily booted in and I got about halfway through initial setup and it died and returned to the same behavior.
What do I do now?

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!

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.

The rom restores I can see that holding true but after 2 complete resets and not adding any apps... not even setting up any Google services I don't know what it would be
