Hi guys,
I just bought a Nexus 7 2013 Wifi Tablet, 32GB edition.
Used it for a while, and I had a problem with the software keys so I tried to unroot it using SuperSU.
Right after it unrooted, I heard a small 'pop' and a big smudge appeared on the middle of the back side of the device.
Before it happened, I think SuperSU said something about some cores.
Anyway, I don't have any problems yet, but the smudge is still there, and the texture of where it is is very soft and smells burned a little bit.
What happened to my tablet?
Hardware failure. RMA it.

May be the battery failure. Had similiar thing on my diamond2.
Battery were working fine, but if you touch the bump phone always reboots.
Wait...does that mean SuperSU caused it?

Who knows, could be a coincident.
Most likely, your battery is damaged. There isn't much stuff in the middle:

Damaged lipo batteries like to go up in flames. If I were you, I wouldn't recharge it (especially dangerous) and replace it as soon as possible.
What did it say about cores? Was it real hot?
That is too freaky!

Almost certainly a coincidence I think. Sounds like the battery has failed, as mentioned, as that's where it is on the device.

Surely if he got through the rooting process then he no longer has any warranty?
Ok, update:
After I had read your replies saying it might be the battery, I tried and recharged it with no problems.
Also, the battery health in the battery monitoring application shows 'good', with normal temperature and the voltage is nominal.
I had no issues whatsoever, not with battery, performance or stability.
Funniest thing- when I woke up and checked the tablet, there was no smudge.
After a few minutes of usage, the smudge reappeared.
Maybe it's just my finger that holds the tablet or something?
I think I panicked without just.

If he can get it on to see the screen he would be able to unroot it and send it in. Smudge or not its better to have a brand new one that works before you go customizing an out of box POS. In my opinion.

I'd consider opening the back of the unit VERY carefully and having a look to check that the battery hasn't failed. You don't want to be regularly charging, discharging, and carrying around with you, a failed Li-ion battery.
I noticed similar smudges around the Nexus logo on my 32GB as well, except I never heard a popping sound. I've been dealing with a bunch of random reboots too. Even stranger, they only seem to happen (as far as I can remember) when its unplugged. I never considered a battery failure before, since it holds a charge and recharges just fine, but there could be something to it. I think its worth looking into a little more.
Definitely a hardware failure. I'm running my N7 at 2.2GHz CPU and 647Mhz GPU with no issues. Battery is obviously an issue, but it hasn't blown up on me, yet.

Actually, I noticed myself that the smudges are perfectly around the Nexus writing.
I mean, like an outline of some sort- but they cover a little bit more.
About the 'pop'- i'm not so sure now it was related to the tablet, as I heard other 'pops' now in my room, probably because of the weather that gets cold during nights here.
I'm not even sure now there is a problem... as I have ZERO issues (the battery is great btw).

No random reboots? Lucky you. Wish I could figure out what was going on with mine. I'm having terrible luck even capturing a log to take a look at.

The adhesive used to glue the Nexus lettering in is notoriously smudgy so it could be you're seeing that leak out from behind the letters.
If it's charging okay it's probably alright.
Yea it must have overheated or something....,

I'm inclined to think this^^ is what you are seeing.
I have the 32GB LTE version and the first time I saw the smudge I thought it was a stain it picked up from somewhere. It isnt very visible most of the time and only shows up when wet (sweat?)
Tried rubbing alcohol to remove it - Didn't work. However the smudge showed up very clearly when i wiped the back with alcohol and disappeared as it dried. The pics attached shows this better.

I have the same problem. I have done factory reset, wiped, flashed different ROMs and still have the same issue so I believe it may be a hardware issue but not sure. If you run an AOSP based ROM, AOKP, CM9 it still recognizes it as charging but does not give you the high voltage message. I went back to stock to check it and it gave me the high voltage message so I think it is part of Touch Wiz. Also on TW ROM, it caused problems accessing the SD card unless battery was low. Although not as bad without the message on AOKP or CM9 it still causes the battery to drain. Any suggestions would be appreciated.
Thanks!

I took my battery out for like 5 minutes,and is not doing it any more,and is showing 82% battery,i think the problem is when you connect the charger,try removing the battery for a while to see,i will not connect the charger now,but later on i will and see if it does it again.
I had this problem as well. Took it into sprint they said the battery was bad and gave me a new one. I have not had a problem since

I have also had this problem, but managed to fix it. It's a risky procedure (could break charging port if not careful) but, if you look at prong that accepts the cable, it may be slanted or crooked in some way. This happens due to ripping the cord from your phone. Your supposed to grab and pull by the head of the cable and never the actual cable itself. What I did was found a small enough object and wrapped the end of it in scotch tape to prevent damage to the prong. I then slowly pried up on the left bottom side of the prong since it looked as if it were slanted, one it looked like it was level, I then pried up in the middle of the prong since it was still sitting a little low to the bottom. After that all my problems ended and have not had another issues with it since, although I have had to do this twice now, it works every time.
My brother had this problem with his phone. He had to get it replaced. It did the same thing for all batteries mostly charged and worked fine when the battery was low.
I have 3 different batteries so that is not the issue. The connector looks straight but I tried messing with it a little to no avail. Looks like I will need to unroot and take it to Sprint. thanks for the suggestions.
Just a forewarning, this is also a common symptom if minor liquid damage around the charging port. It's 50/50 at my store, sometimes I open it up and there's corrosion, sometimes not.

It depends on where it's at. My E4GT had a tiny water spot on the board where the battery makes contact. I set my phone on the counter to charge one night and didn't realize my roommate had left ice on the counter after making a drink, the ice melted so there was standing water there and it was late and I had been drinking so I didn't turn any lights on, water got behind the battery cover and changed to indicator on the battery but not the phone itself. It wasn't wet I allowed everything to dry out by doing the rice trick.
I bricked a couple months down the line and after taking my phone into a sprint store the tech showed me the corrosion on the board and then cleaned it up with an alcohol based solution. Then referred me to file an insurance claim. I sent it into Samsung instead.

Mine now doesn't shutdown,i turn it off and it just turn it self up on its own,i even remove the battery and when i insert it back it turns on on its own,i am not blaming ICS but the other rom i have before it never gave me any problems.
Also my battery drain incredibly fast,to the point of 7 hours of mild use would have me empty,running a game for like 20 minutes will lower the battery from full like to 55%..
Some times i just remove the battery or restart it,and the drains stops,but as soon as i restart or charge the drain start,even when basically all apps are close.

what i did was get a q tip or something small like a peeve of paper folded so that it is sturdy and scraped out the charging port. a lot of black stuff and dust was scraped out. never happened for me since then. make sure you get both top and bottom part of the middle prong

I just got my note 2 yesterday. Whenever I set it down on a hard surface a little bit abruptly. It restarts!
And there's a certain place in the back of the device I can tap to restart it.
Is this normal? Are these devices really that fragile????
Mines an international one from France so warranty is going to be a pain ughhh...

sounds like you got a bad unit.
It could be the battery is shifting around when you set it down hard.
Normally I'd just say send it back, but if a warranty claim is going to be problematic, you could try padding the back cover with some paper to hold the battery in place a bit tighter and see if this 'fixes' your issue.

Dave

Just done same test three times with my unit and it remained on, no restarts. You just got yours...so maybe you are still in the exchange period. I would get an exchange because it is not normal behaviour. You should have no problem getting an exchange. Just try to avoid telling the retailer that you've also been getting the problem when setting it down on a hard surface 'a little bit abruptly'. They will gladly play the "you've damaged it" card

If you can't get it exchanged, then use a thin tape or something of the sort to hold the battery in place.

Wow this seems to have worked, this is the first day it hasn't rebooted since I got it! I did notice the battery moved around slightly when I opened it up, so I'm guessing that was the issue.
Do you think leaving it in there is dangerous? Like it will overheat and catch on fire or something?

So I didn't start having this problem until almost 2 years of owning the phone, but since then, it's been happening quite frequently. Sometimes it restarts and sometimes it simply turns off (this is quite annoying being that I miss many texts/work emails).
Well I decided to do some research and I came across some people saying it could be the battery coming loose for a split second.
I decided to try folding a piece of paper a couple centimeters (about the depth of the battery) and jamming it under the battery to push it up against the terminals. Much to my surprise, my phone hasn't restarted when bumped since!!! (Fingers crossed!!!)
I hope this helps, although I know this is a little bit late for most people, being that the Note 4 is already coming out. Better late than never!
So i'm having 2 issues
1) you can see in the 2 of the pictures there is an area of yellow discoloration. I had this problem back when I got an iphone 4 and returned it the next day. But because wirefly has such crap return policies I rather keep the phone if this really usually is a temporary thing while the "glue settles" as been reported in the past
2) I'm getting this heat error when I try to increase the brightness of my screen. Today is the first time I tried upping it beyond the normal 63% due to trying to check out this discoloration issue. Note I did have an otterbox on my phone at that time but I wasn't doing anything CPU / GPU intensive. It seems a little ridiculous that the heat would not let me raise the brightness just on normal use.
Wondering if anyone else is having the same type of issues

I got the heat issue one time... i've seen others say they got it as well. I don't normally have my brightness that high though and when I got the message it wasn't really very hot. It does heat up during games and stuff though.

I am having the same issue. I bought mine last night from Best Buy.
Thanks guys, i'll wait and hope a future firmware fixes the heat. It didn't feel that hot in hand. The yellowing looks better today.
I put mine on the charger 30 minutes ago and the discoloration was gone, but as I was using it you could see that it was returning..
Not having any of those issues. Just traded my GS3 last night for this and loving it. Was able to get the screen to the full 100%. I normally keep all my phones displays at 0%. I guess I have sensitive eyes. Unless in sunlight.
The screen not being able to go to 100% is not a defect. It has been discussed in a lot of reviews for the phone both att version and Sprint version. As far as the yellowing of the screen if it doesn't go away soon I would say it's a defect.

Thanks for the info Wally! I haven't seen those reviews, can you point me to them. So you would say not being able to go to 100% after just normal use is something that should be normal for a phone?
Speaking of defects, has anyone else noticed the color-banding issues on the display? Is there a way to re-calibrate the gamma on the display (As I'm sure that's the reason for the banding effect)?
Yep, I have the yellow screen at the bottom as well. Bought at best buy last night. Probably going to exchange it, but waiting to see if it goes away after some use.
Update::
I guess this is good news. The yellowing on the bottom of my screen has faded to almost half the amount it used to be. Its still not totally gone yet, but it does show promise. Perhaps this is the same issue that many iPad users had with the adhesive curing with heat and use.

I bought one from zwxj on Amazon a couple of weeks ago. 20 minute install. Very easy. There a a few youtube videos you can search for that show the entire process.

I bought one from new power 99, was getting 10% loss for every hour for the first few months but then it started to go alot faster. They have a 1 year garantee on there batteries so i just wrote them 2 days ago and explained what was happening and they sent me a replacement the day they got my email. It was a little more expensive but definitely worth it. They also told me to just keep the first battery. So i would definitely recommend them . They didn't argue or tell me I'm doing something wrong when I sent the email , they just shipped a new battery out. It comes with all the tools to take tablet apart and was very easy to do.
So my battery is fine except when playing games. It's drops insanely fast. I have a refurbished model and am thinking a new battery should do it. Anyone have that issue and a new battery take care of it?

My battery life is getting much worse, and the tablet is now 2 years old. Looks like time for a new battery here too...
Don't know if I need one yet. I know I leave it on the charger quite often and it seems to drain much faster under load than my refurbished nexus 7 2013, but standby time is much, much longer than my nexus 7. Disassembly also seems like a pain. I don't like that you have to pry on the screen

Like the rest of you, I'm experiencing severe, and rapid drain from my battery. I just bought a brand new OEM battery for my tablet. Hasn't come yet, and I will let you know about any difficulties. YouTube videos make it look like a fairly easy job, and it doesn't look like there's much pressure on the screen while you do it. By the way, just for giggles I decided to check how difficult it would be to access the battery. Take it from me-DO NOT TRY TO PRY THE SCREEN LOOSE! You might lose the power and volume switch caps. Only remove the screen if you need to replace it.
Rather, pull the S Pen from it's socket, and gently pry the back cover loose. From there, follow the directions on YouTube carefully. When you are done, gently reseat the rear cover, and make sure that it's properly seated. You'd never believe that piece of chrome coloured plastic was so important. Sheer Genius!
Well, hope that helps.

Get the one used in the most wellknown tutorial vid, from Newpower99. I wonder whether they ship overseas.
Any way to check to see how much power or life your battery has left? Just bought a used one and seems normal.

i got it from zwxj on Amazon. it was cheap. it was actually very easy to install. there was a small issue though. the cord that connects the battery is a little to long. and the plastic piece at the top isnt exactly correct. i was able to get it in though with minimal effort. they battery lasts forever. the only issue i have and it is a pita is it will randomly shut off when playing a game. doesnt happen all the time and there is no rhyme or reason to when it happens. i need to plug it into the wall and then it will restart with the same battery it shut off from. i could read things all day down to zero and it would never happen. wither way for the 15 bucks or so i spent on the battery it makes the tablet usable again and i love it.

I've bought one from AliExpress with the same issue in the little plastic piece on top so I guess it's from the same manufacturer. Mine constantly turns off. Even updating apps. It seems to be an issue with these batteries.
Also, I feel like it doesn't show the correct percentage. Is there something I should do after replacing the battery for it to show the correct percentage?
One last question and this goes to everyone. Using Ampere, could you please check and tell me whats the average drain in mA?
Thanks!
I use Battery Monitor Widget, included in the 3C Android Toolkit, and samplin battery data in sync with Android to save power. So Standby values should be too high to be representative, 0,05 to 0,2A. Idling with screen on, around 0,6A. Max Load should be over 2A or ten watts. These values should be calculated from the battery voltage instead of the Usb voltage. Attached to a power supply, the Note never seems to drain the battery, so there must be a ten watt power limit, it will simply no longer charge under full load.
Using improper plugs doesn't sound like a good idea, the contacts could get so hot, that the plastic of the plug und socket or the back cover could melt and the contacts could de-solder themselves from the main pcb.
Just ordered a OEM Samsung battery today. Will post when I getvand get it installed. Battery is totally flat on my device.

i got it from zwxj on Amazon. it was cheap. it was actually very easy to install. there was a small issue though. the cord that connects the battery is a little to long. and the plastic piece at the top isnt exactly correct. i was able to get it in though with minimal effort. they battery lasts forever. the only issue i have and it is a pita is it will randomly shut off when playing a game. doesnt happen all the time and there is no rhyme or reason to when it happens. i need to plug it into the wall and then it will restart with the same battery it shut off from. i could read things all day down to zero and it would never happen. wither way for the 15 bucks or so i spent on the battery it makes the tablet usable again and i love it.

I had the exact same thing happening with mine after replacing the battery. Check your CPU clocking. If you're on a CM ROM it's probably overclocked & set to 1900MHz. If you set the governor to 1300MHz (which is the factory clocking speed, I think) it should quit shutting down like that. That's what I did and I haven't had it happen even once since. I think the CPU is just overclocked a bit much for the aftermarket battery to handle. Your tablet will run a bit cooler this way too.

I just replaced my battery as the tablet had become unusable. I found the same issue. Only happened once, I also found that I could only charge the device while off, I reseated the charging flex which seemed to correct the unable to charge while on. Now that I think about it, I was on a TW 4.4 rom rooted when it happened, I'll report back with findings.
I contacted Samsung support and they referred me to a distributor of official OEM Samsung parts. Ordered a battery last week. Unfortunately, delivery is in the 2 to 3 week timeframe, as it's coming from overseas. I will let you all know how replacement of it goes.

If you want or need directions for replacing the battery, when I did mine about a month ago I posted a step by step guide for what to do along with pictures (just ignore the part about removing the charging port if your only doing the battery). Here's a link to it http://forum.xda-developers.com/showpost.php?p=66124495&postcount=13
HI.. I have the Tab 3 8" SM-T315
2 weeks ago, it wouldn't charge up all the way, and the battery ran down SUPER fast.. Even when powered off.
It's about 4-5 years old, so I paid for a new battery to be put in.
Guess what?? Same deal.. The thing gets hot in the upper left corner EVEN when powered off.
And the thing is discharging like crazy.
Plus it wont fully charge at all.
I cant get no more that 2hours on the battery after about 2/3'rds charge (that's all she'll take) when on, and when off, the hot corner is still there..
Well maybe not real HOT, but more than warm. ON, Charging, and OFF.. still stays good and warm, on and off the charger.
Can any-1 care to make a few assumptions??
This came on all of a sudden with NO additional apps installed in over 6 months.
F/R, wipes, etc.. Flashed latest rom from Sammobile last week.
Thanks alot to all who reply.
Youtube disassembly videos of it on youtube see what's in that corner. Bluetooth? Wifi? GPS chip? See what's bad. It's most likely a hardware issue. Any drops or water damage?

Thanks for replying, nope no drops, no water damage, no nothing. It's sat for about 3 months with no activity. But did charge up fine. I used it for about 2 weeks then all of a sudden one day I noticed it wouldn't charge up all the way and the corner was hot. Just last night I got it to charge to 90%. Powered it down, and in the morning battery is completely dead. Something is making a discharge even a while it is off. I guess I need to find somebody who can work on it.
Most likely unless you're comfortable with disassembly. Like I said what's bad maybe easily replaceable. I bought a wifi Antenna for my s3 on ebay for like 3 bucks new

Thanks again , nemisans13.!! I think I would like to try this assembly, I would feel comfortable doing that, but I have no way to test for bad components once I get the cover off. I've seen the YouTube videos how to change the battery. I feel confident I can get the cover off and look around. But I wouldn't have any idea on which component is bad. Can you help out on that?
Thanks again
Wish I could. Why I said look up what's in that corner on youtube see if it's replaceable and doesn't need resoldering or anything crazy like that

If I give up and wuss out, do you know of any tepair places that are reputable?
Thanks
Look up gadget drop. They've been known to fix issues like that.

Well, nemisans, i just called 2 places here in STL. The 2 most popular, FoxPaw being one of them.
And they said that they do not do the micro soldering stuff and chip replacements. Only screens, charging ports, etc..
SO it looks like im gonna have to mail it to Detroit.
Any favorite location that you recommend?
Thanks
Any of them should get u fixed up
