[Q] Overheating

So, for the past month and a half, I've been having some serious overheating issues with my E4GT, whether I have it rooted and a custom ROM flashed, or running stock. It has now gotten to the point where the phone smells..funky, near the camera on the back. Now, Sprint labels the battery as the culprit...twice now, they just give me a new battery saying the old was swollen, and that it is what was causing it to overheat. Completely ignoring that I state it smells like fried parts. Now, the batteries were all normal in appearance, mind you, not a bit swollen. No water damage either. It gets almost too hot to touch the screen at times, not dangerously, but uncomfortable. I only use the USB cable and wall adapter it came with, as well. ..Yet, battery life actually isn't terrible, go figure. This overheating happens whether I am using the crap out of my phone, or just leaving it sit idle.
Any ideas what to do from here? It makes it almost too hot to touch the screen at times, not dangerously, but uncomfortable, especially if it happens when I make a call. I only use the USB cable and wall adapter it came with, as well. I've made a habit of unplugging it when it says it's at a 100% charge, too.
I'm sick of Sprint shoving me aside every time I go there, which is three times now. So, if there are any ideas as to how I can get them to just replace the damn thing without spending 100 through insurance..lay it on me. I've searched the forums for a solution to this particular issue, no avail. Hell, if it takes purposely bricking for them to pay attention, then I'll do it, but that's on the back burner. Far far back.
I have tried all sorts of things to keep it running smoothly, I guess my main question is how to get Sprint to just replace the dang thing.
Apologies for the novel, guys and gals.

Go to a different sprint store....they're being dicks, never had that issue at any sprint store in my area. You have a fault phone and it needs to be replaced.

I had the same problem and so did my woman. Do yourself a favor and download Calkulins battery saver E4GT ROM. I don't know how but it keeps the phone cooler. Seriously. Haven't had any over heating issues since. EL29 stock kernel always causes mine to heat up. Hope this helps

I've used that as well, but the thing still smells pretty bad whenever I use..well..anything. :/ I have tried all sorts of things to keep it running smoothly, I guess my main question is how to get Sprint to just replace the dang thing. I should add that to the initial post...

Do you have insurance? You could always just brick it to the point where all ya get is the blue led of death and bring it in and tell them the thing just suddenly went off on ya and when you tried to turn it on this is what happened.
Do NOT try to damage it using water because they have these stickers inside the phone and on the battery that change colors when they come in contact with water so sprint will know, and laugh in your face.

my phone also gets very hot like in 120 range

You could send it to Samsung under warranty, and when u go to sprint make sure its a corporate service center and not a 3rd party "authorized service center". When you go in don't mention overheating at first start off with "my phone smells funny, like burning plastic and when I pick it up I notice the screen is very warm/hot to the touch and sometimes has issues with the touch responsiveness" this should get their attention away from the battery and more towards the internal issues, more than likely its the SOC that is overheating if it's hottest near the camera area of the phone

[Q] Phone melted. Need to return. Rooted. What to do?

I'm a little concerned about my current predicament.
A month ago I bought a rooted Galaxy Note II second hand. I have had no problems with it until Saturday morning.
On Saturday I plugged it in - it was flat because the battery had ran out of juice from the previous night. I left it off and plugged in. I returned not long after to a slight burning smell, and the phone was roasting hot.
I could turn it on, but it hasn't charged, still showing 1% and cutting out immediately. Any time you plug in within seconds, it overheats.
It has burned in one spot, and burned the battery cover as well.
Obviously I am not impressed, it could have burned the place down if I'd left it on overnight.
However, the device has been rooted, and can be turned on but it will damage it more if you do. It has had a theme applied to it that could only be done with a rooted phone so it is blatantly obvious.
I've put in a support call with Samsung who are going to send out a bag to send it off to them in. I would have preferred to send them an unrooted phone, but obviously not practical and I don't know anyone else with a Note 2. I also don't want to buy replacement components in case I make it worse or damage those.
Anyone faced a similar predicament, and what was done about it?

Well, in this case, a melted phone is very dangerous, they should or must send you a new one just to not report it to the police or the media!
I think the problem was in the battery, it's the only component that can get so hot and even it can explode in some conditions.

My concern is they try to say that it was the fact the phone was rooted that caused it to overheat... although it was switched off at the time.
Don't worry I won't let it go without a fight, but am unsure about what rights I may or may not have.

Try to run triangle away, before you return it.

Phone is totally flat, and will only turn on when the battery is connected, and it is connected to the mains. It will overheat with a minute.

In Norway, and I assume in the EU too, they have to prove that there is a connection between the broken phone and the fact that it is rooted to void warranty. No worries then if there's similar legislature in your country.

What if you charge it with usb cable connected to a computer? Does it still overheat?
Alternatively, do you know any1 with a note 2 whos battery you can borrow?

Try buying a spare battery. And then try triangle away. Put the faulty battery back in the phone and send it to Samsung.
It's way cheaper than having to pay for the full phone repair.

This thread's funny. A second hand phone received or bought rooted which could have been using a different kernel, been OC'd, or had any of a laundry list of mods done to it overheats. Since none of that can be ruled out, why is there any reason to alert the media or expect Samsung to be responsible for something that's most likely not a defect but customer induced damage? With millions sold I'd expect more reports of phone's melting if there was some sort of common or repeatable fault. Best of luck OP but your fate will be determined by Samsung's graciousness and not you claiming that a rooted second-hand device somehow combusted on its own having nothing to do with what you or the first owner did to it.

To be fair if it's not charging the battery at all and just overheating/melting the phone it sounds more like a hardware issue than a software one. Something in the charging circuit is screwed up by the sounds of it.

idk if this help, last time my S2 also got some issue so I go to SC and the guy there said that I voided my warranty coz I rooted it.
And that statement made me angry, so I said to him in angry tone: why the hell you say its illegal to root and voided my warranty becoz I root my phone. If that's illegal, why the hell Superuser/SuperSU/any root tools exist in Google Play and Google let it in there for a long time? I bought this phone by my money so I have right to install anything in play store.
Then they unable to say something and fix my phone rightaway and told me to be careful next time.
So, rooting isn't illegal, its in Google Play anyway.

ask yr friends or someone borrow a battery and reset the counter first

I don't know anyone with an N2 so I can't borrow a battery, I'd have to buy one.
I'll try plugging it just into the computer, I suppose with less power going in, it might not overheat. I've been reluctant to plug it back in.
Phone is running standard kernel, it was only rooted, with a replacement status bar added, and CWM installed. Nothing special.
Ideally, I would need to flash it back to standard though, so I'll need to find out the easiest / quickest way to do this, and, possibly, reset the counter.
I suppose its possible they will refuse to fix it. If I am, that is me massively out of pocket, and I won't be rooting anything ever again, even buying second hand is losing its appeal.
Heck, as I can't afford to replace it, I now may be stuck with this Nokia Lumia 800 I had to buy as an "emergency" phone, which is actually not a bad little machine in many respects (obviously tiny though).

Given the near fatal consequences of a battery explosion you shouldnt have any problems Samsung will be much more interested in working out why it happened and avoiding any negative PR about their flagship handset.
However if they can proove that it was the root that caused the burn out (we all know thats not the likely reason) then they may reject the device and tell you it was all your fault. at that point take it to the media.
to me it sounds like the charging circuit has failed and instead of passing charge to the battery its built up in the circuit, mechanical failure can't see how a root would cause that. Were you using the sammy charger, cable and battery?

Ye that was my thought wonder if OP has original sammy cable and charger or was given a third party one?

Yes I did indeed use the original charger and cable (it looks original too, not like a knock off). In general, in the past, I've had issues using chargers mean't for other devices, usually just slow charging though rather than it blowing up.
The fact the phone was turned off when it was being charged suggests to me, like you say, that its a proper hardware fault.
We shall see. I'm waiting for the jiffy bag to send it back, it will be at least 2 weeks till I get it back (maybe longer now with Xmas coming up).

Take a picture of the burned note2 first, maybe you can use it as a "leverage" when the time comes. You know how burned phone have negative impact on products marketing.

[Q] If anyone could give a s***....

No one ever seems to respond much about hardware issues on the note 2 forum but I'm going to give it another go. Started out a few weeks ago with major battery issues resulting from what I think caused it, was an overheating issue. (fell asleep laying on it charging and screen lit for about 6 hours) The phone started by shutting off when the levels were anywhere from 20-50%. Since then I've tried 3 new OEM batteries and swapped to a different working charge port flex. I jumped from cymod to the skynote rom before swapping out hardware parts and it seemed to make a difference at first but didn't last long. Since going to skynote, I've tried running with greenify, juice defender and no power saving at all. Tried normal performance and tweaked performance. The other night I had my phone off and charging and it reached 100% on the power down indicator, when booting the phone up, the status bar battery indicator said 81%. The next night my phone actually stayed on, or atleast displayed what I felt was the proper percentage, down to 1%. When the indicator went from 2% to 1% I received a notification to unplug my charger, that my battery was full...the charger was not plugged in when receiving this and as soon as I finished reading the notification, the phone shut off again. I am at a loss because I have no idea what's causing this. I own an electronic repair shop and have no problems soldering new charge ports on if needed but I'm starting to think there is another controller on the daughter board which may control the communication between battery and phone. Any ideas?? Anyone....hello

Dear Pissed off in PA,
Every post you've made has had help and/or follow-up questions asked to help you. So that disqualifies your "no one seems to answer hardware questions" statement.

#1. You title of your question isn't cool, I don't care if your pissed off. Remember there's kids that come here for info and to learn!! No one here caused your PROBLEMS... self inflicted wounds...
#2. If someone didn't answer your question probably means we didn't see it or just been busy and it got over looked!
#3. We try to help each and everyone with a problem...
#4. Now to you problem:
First off yes it's VERY BAD to smother any device (6 hours ouch) that's constantly running. Especially with a battey power, being if the device isn't breathing it's gonna over heat. It's kinda like blocking the radiator on your car while your racing down the highway. What do you think it going to HAPPEN problems!!
You mentioned a few battery monitoring apps! [emoji107][emoji107][emoji107]
Get away from those apps cuz most of the time they're wrong or reading the battery level wrong! I'd recommend BBS go here»»» http://goo.gl/0TeXcR
But from your post seems something in the phone, might be something minor got over heated to much which is causing your problems.

The only one that ever offered anything that wasn't a typical response to someone who knows nothing about gadgets, was steele. As many times as the posts were viewed and only getting one response, which most of the time was an unrelated answer, is pretty sad. When noobs have questions about flashing a rom, there are always 30 people there ready to tell them or berate them, when there are countless forums out there to find their own answer. And no, only two posts had answered my hardware questions and the replies were not any kind of a valid response. I apologize for assuming anyone here had experience with internal components. How about instead of responding like a troll, you change my mind and actually teach me something if you're so qualified to give tech support.

Thanks for your input, but I'm looking for the contoller that would have been damaged. Do you know of a motherboard breakdown link, where I could find out which ics controls charging/battery/phone communication or shutoff. I've soldered new contollers in iphones before and I'm assuming there has to be a similar part which controls current shutoff in the galaxy line. Thanks again.

Thanks. I've done the calibration a couple times with new batteries and flashed quite a few roms on and off. I'm pretty sure something is cooked, but most of the time, if the ics can be identified it can be replaced with a new one. I'm looking for a motherboard breakdown of all soldered parts and a legend to go with it. ifixit is where I usually go, but can't seem to find the exact breakdown of what part controls current flow and shutoff.

Xda is mostly about tweaking the phone software and very seldom about the hardware, and rarely about the ic components. Sorry that your question is several paygrades above my skillset.
I have replaced the mainboard for about $80. But of course you already thought about that.

I think that sort of info would be proprietary info, that Samsung would not publish out to just anyone. Unless that specific piece was patented.
I can see them not giving a damn about older models of phones whose technology they would not reuse. But Galaxy stuff in production, I would imagine they would go after someone's scalp that had it.
For info like that I usually grab whatever numbers I see on the board, throw them in every search engine I can think and hope something pops up.

You probably hit the nail on the head with that. It's just so frustrating when I know it can be fixed if I could just figure out which part got fried. Usually soldering a new charge port fixes a lot of hardware glitches when it comes to connectivity or charging/decharging, but of course on this phone it's not happening. Thanks steele

LG G3 shutdown due to high temprature

PHP:
today I experienced a new issue and I want to share it to see if anyone have the same issue.
when I was using my device today a warning window came that says the device has detected a high temperature issue and will shutdown, and the device shutdowns.
I don't know if anyone had the same issue before so if anyone have please say.

Let me answer you through question... What does your pc do when it overheats?
Usually reboots or shutdown, right? It is same with phones.

Dont force your device so much in overheating.

@droidhd is a total asshole. Treating people like that is how he gets off.

Thank you dear. You all are so smart, but none of you gave any other advice or tip what could be wrong. That's why you need attention like this, to tag others with that speech... Good enough *sarcasm*

Overheating, random reboots or shutdowns?
Yeah .
I picked up 4rd LG G3 32GB phone yesterday. All older have overheating defect (and I guess this one will made no different). Its big beast with a lot of power and there seems to be some bugs to deal with. Im sad too, I want to keep this phone and not change to another one.
Just quick test from rest of you: run Antutu benchmark like 3 times (you can restart it after 30% after CPU tests). Sometimes Im unable to make one single run of benchmark and phone shutdown itselfs. Great.
(oh, EUR edition, metal black, 1st wave)

Took my g3 on holiday with me, phone was in my pocket not used for a while. Took phone out pocket to get some holiday snaps, after taking 3 pictures with the stock camera phone over heated and shutdown. Great photo opportunity missed. Took phone back off and battery out so could cool quicker,and left to one side for 45 mins to an hour. Was an overcast day and not very warm. Put phone back together turned on, and fired up the camera. 4 pics later, warning phone over heating, will power off. What good is the camera if u can't use it, missed some good pic opportunitys. Not happy.

Overheating has been addressed in builds 10G and later - what firmware you running?
Also did you disable Thermal protection in the hidden menu (it is billed as a way to reduce lag by some numpties on xda) - doing this will cause your phone to get hotter quicker and stay hotter for longer thus increasing the chances that it will shutdown for overheating.

I'm running 10g non rooted, did do the thermal trick at the time, so maybe it was that, have since disabled as noticed battery drain was a lot higher. Haven't tested camera yet though.

Let me answer you through question... What does your pc do when it overheats?
Usually reboots or shutdown, right? It is same with phones.

I know that this can happen in laptops but In phones this is the first time to happen to me... especially the warning message
I just wanted to check if there is anyone else had the same message...
another thing is that there are times when my lg g3 is hotter that when the message came (especially when using the phone while charging) but the message didn't came... so I don't know how is this heat shutdown thing works.

i'm in 10G version and i'm rooted and having the thermal detection off.
ohh I remembered another thing... when the phone shutdowns I was not in the visible sun so it is not something related to sun exposure... it must be something with the software

Salahhuss, can you tell us what you did with the phone that you got that message? If nothing, get yourself betterbatterystats (search on xda) and check what makes you wakelocks...

I'm using the phone right now as this issue happened only one for me so i'll wait and see it happen again then i'll contact the supplier to check it.
In the meanwhile i'll try the program you mensioned and see the results.
Thanks for ur help ?

Seems to me that the heat sensor on the batteries often malfunctions and you get this issue. If you wrap some tape around it to keep the top plastic pushed down against the battery pack the issue might go away.

I think I am having this issue on a G3s, the phone used to work normally but lately I can't even run it long enough to get my photos off of it because within 1 or 2 minutes after turning it on it gives the temp warning and shuts down, the phone doesn't feel warm and I wasn't using any apps. I don't understand where to wrap the tape, where is the heat sensor located? I'm trying to push the battery against which side exactly?
Update:
Just having the info that it could be the heat sensor of the battery was helpful, I tried swapping the battery from another phone and the problem seems to have gone away at least for now. I was able to connect to a computer and copy over my files. Will be keeping my fingers crossed....

tab gets flickering screen and reboots

I dropped by tablet battery down once and now every so often the screen flickers with vertical lines and this is followed by loss of network and the thing reboots.
I've read this to be a battery problem.
Warranty is still active but I've rooted it and my Knox counter has gone up.
What do you think XDA? Just get a replacement battery?

If you have the ability, since it was dropped, I would open it and make sure connection is tight to battery and screen. Then if it still acts up, get a battery. Several people had battery issues out of the box. All it turned out to be for a few was a loose connection.

i was thinking about that but i'm afraid of voiding warranty. do i even still have warranty? due to the knox?

Well ive opened it up and tightened everything i can see and it seems to work ok for a while, when the charge gets to around 20-30%, the tablet flickers, all mobile connections are lost and 75% of the time, reboots.
So i went ahead and got a new battery. Now this was worse kinda. At random moments, like unlocking the screen, or replying to a message, or maybe just a high cpu load event, the tablet just turns off and is unable to be powered back on without first connecting it to a power supply like a wall charger or a power bank.
The time and date will be reset once its back on and ill have to wait a few minutes before the auto network time setting kicks in before i can use something like whatsapp.
Anyone got any clue what might be causing this problem? Thanks in advance, helpful xdarians.

I'm not by any means an expert or repairman of any kind, just so you know. I'm thinking maybe a loose connection at the terminals on the board the battery connects to or if they use a separate board for the battery to connect to and then to the main board it may be somewhere along in there. Maybe a loose wire going into the tab that connects to the prongs. It sure sounds like something isn't making a good connection. Sounds like a load gets put on it and it and that bad connection can't handle the load.
Might just be you're going to have to send it off...

You may be right. Sounds like a particular connection which does higher load or something. Once i put the tablet in power save mode, the symptoms never reappeared. I dont notice a drastic slowdown in the tablet either. Probably am prolonging the inevitable.

Same Symptoms

I am facing exactly same issue what you have described and am in same situation, have tripped Knox on my Tab S 8.4.
I can see that you have been able to suppress the behavior by putting it to Power Saving mode. Have you experienced flicker and reboot since then? I am planning to take it to Samsung store not sure if they will honor warranty, did you tried that?

nope, ever since the Power Saving mode solution, it hasnt flickered and rebooted yet. and my warranty was expired by that point so i didnt bring it to the shop. no noticable reduction in performance so far

possible battery connector

I have seen this problems on 2 tablets 10.5 and 8.4 the connector where battery is connected on motherboard gets loose which causes reboots and flicker
Solution in my case was resoldering that connector again

i had the same problem, opened up my tablet, just disconnected the battery, cleaned the contacts, pushed it back, made sure its nice and snug, put it all back together and now battery doesn't drain as fast, no more flickers and reboots!

hmm. i'll have to give it a try. you think this may be something to do with condensation?

Sorry for the bump, but I'm having this issue as well on my S 8.4. Custom ROM. The thing with me is that it's not consistent. One day, it will do it a few times; others, no issues whatsoever. I'll try the suggested if it gets progressively worse.

Hey guys,
Unfortunately our home's tablet (Tab s 8.4 Wifi) has the same problem.
It never did weird whatshowever, but when I flashed a custom rom (which went perfectly smooth actually) the screen flashes and the tablet reboots sometimes.
Now it weird that this never happened before and only when I flashed a custom rom it began showing this behaviour.
I am affraid of opening this tablet, and I guess because of the custom rom there is no warranty left anymore (or can this be bypassed by some terminal trick?)
Also I question myself if this is not a software issue, and that it can be fixed with software or so?
Thanks for answering!

My Fix
Hey Guys!
I might have some surprising news to tell about this "issue".
I saw some unboxing video's and saw at what place the battery connector was placed. It was some sort of a 'push to click' system.
So what I did was the following:
I pushed the tablet at the place of the battery connector. I tried this at various places until I heard a *click*.
Now I don't have this issue anymore. Jay!
I hope this will help you too!

I started to have the same issue on a Tab Pro 12.2, presumably after the battery has lost considerable amount of its energy. Normally I remember this tablet to have a dazzling 10+ hours of usage time. Just after some serious usage time of more than 2 years this issue started, along with increasing temperature and finally reboot. From time to time Android gave a warning message about overheating. From time to time charge values drop big values at a time. From 45 to 20 or 80 to 50. Seems arbitrary. This was happening even when I was on stock, then I switched to some Android 6 stock port from some other tablet. Still the same.
I believe the battery needs replacement. (That's obvious after 18 months, I just mean blinking is related to this) Hope I can find a high quality one cause there are several garbage batteries.
