[Q] CPU overheat and crash, help?

My wife's Epic 4G was working fine yesterday but today it crashed and overheated pretty severely. When it was still plugged in and crashing it showed the battery charging and then it turned yellow and show a yellow warning triangle with a thermometer beside it, is the phone going to stop working on us?
I would appreciate a quick response so I can take it to Sprint and see what they can do about it.
I just factory reset it to insure that it wasn't a rogue application or what not and the phone is still running slow, not as bad as when it was crashing, but it still works so I don't know what's going on with it.
Also the phone is stock and has always been stock without root or any other type of hacking, etc.
It just stooped working perfectly one minute.
She showed me that the screen was blinking rapidly in an up and down bar fashion on the home screen and during applications.

First of all how old is the phone. My phone runs games hot all the time and never crashes (well sometimes, but usually when im not even doing anything with it).
I would think that the video is going out on it and it is rebooting. Depending on the age I think your phone is dead dude.

Not a year yet, it'll be a year old in June or July. I'm hoping it was just a virus or something because its working now. Should I exchange it anyway?
Nabbu eats your face.

Try flashing it back to stock or wipe the data if it isn't already rooted. I've never heard of anything of this sort... need some screenshots or something.

It's already stock.

I already factory reset it and it's running right now as if it were just fine but what I'm wondering is if it's going to happen again and not work afterwards.
I'm thinking about taking it in to Sprint and exchanging it but I'm afraid there might be fees for exchanging or what not. The phone has been dropped multiple times but it never had any issues before.
The drop distance has been less then 2 feet every time.
No water damage to the phone itself but the Sprint tech said the battery's "water damage" indicator was activated and showing water damage.
The phone HAS been in the bathroom during multiple showers which might be the cause for the battery's damage indicator to go off but the phone, like I said, has never had any issues.
She downloads pretty much everything from the Market so I was suspecting viruses or malware and now it's "clean" it's running fine.
Any suggestions for where I should go from here?

The phone should be fine. This has happened to me a few times.... if your phone gets extremely hot it will refuse to charge as a safety feature and show that yellow triangle thing... open the back of the phone take the battery out and let it cool down.

That's the best advice i've gotten on here! Thanks a ton! ^^b

Happened to me my battery got near 118*F so I took it out and let it cool on some aluminum and put it back in was fine
BTW you can't take a screenie because phone shuts it self off
Sent from my SPH-D700 using xda premium

I'm guessing that the overheating problem had to do with a buggy app that was running on the phone and took lots of data or cpu time. This has also been know to happen when running wifi hotspot apps.
Regardless, like everyone else said the phone went into thermal protection mode. The battery got hot and it wouldn't charge the battery until it cooled down.

Could be the screen being on and maybe running a governor such as "performance"? Also, I've left my phone under a pillow charging, woke up it was 110F and I haven't had this problem it mustve been really hot

THIS! ^^^ Without looking at your phone, I'm guessing this was the culprit. She had a buggy/defunct app that was probably frozen in the background while still sucking CPU/RAM. I've had a few of those instances and it DEFINITELY increases the temperature of the phone.
Only other thing I can think of is if she runs her phone at the brightest setting and has a long timeout on the screen timeout. Either way, I think it's nothing a little spring cleaning of the apps and tweaking couldn't take care of. Good luck buddy

[Q] Phone turns off randomly

My phone randomly turns off when I'm not using it. (Like when I leave it too charge overnight or don't use it for a couple hours)
What could be the problem? How to fix this problem?
Thanks,
Benwaffle

are u rooted? have cwm installed? custom rom?

Rooted, ardatdat kernel, cwmr. Actually it didn't seem to happen last night, and I just installed the new kernel yesterday
Sent from my SAMSUNG-SGH-I927 using XDA

if it happens again after you changed the kernel, try a different rom and stay away from overclocking it and stuff. can't hurt to inspect your battery contacts if you spilled anything near it.

Turns off or locks? some people are getting it to lock it's called the sleep death and happens if you put your phone to charge at night with Wifi on. Some people try different Roms to fix this issue.

Hehe my phone doesn't sleepdeath...I charge it on with wifi...maybe it's different

That was a very helpful post.....Nah just kidding it doesn't happen to everyone. I have had my phone since December last year and I can count on 1 hand how many times it has happened to me. I always charge at night with WIFI on. But when it does happen I simply hold the power button till it reboots, so not a very big issue to me.

Reviving this thread because I'm having a similar problem...
Running on stock, rooted.
It happens often enough for it to be a problem.
Only concern is when I go to sleep and rely on my phone as an alarm clock. I need my phone to work
Please note last charge cycle on the attached screenshot. Battery was at 84% and completely dead after sleeping for 8 hours. It doesn't even show me how the phone died, or what made it die.
During the day, I think I have the same problem. My phone will simply not turn on at times. I have to do a battery pull before I can get the phone to turn on again.

Check the battery. Take it out and put it on a flat surface like wood or metal. Spin it like you would as a bottle, if it does that, then your battery is swollen and will cause problems like what you're experiencing. If that does happen, you need to replace the battery, as that is your only option. Sorry . It happened to me, but i was covered under warranty.

Battery looks fine. Not visually swollen and doesn't spin on a flat surface. Wish I had another battery to test this out...

I saw that you're using another rom. Did you wipe battery stats and cache before installing it? I remember with my DHD I didn't do that and it would die randomly here and there. After I reinstalled the rom, it was working alright.
Save your apps on TB and do a nandroid backup before doing it so you don't lose any data.
Also, try out the literom, it's basically stock without bloatware.

I've been running it on stock, just rooted.
I don't believe wiping battery stats will do much, considering they're wiped every time you charge to 100%. But the battery level is definitely off. I reboot my phone sometimes and end up going from 50% down to about 10%. It's not reporting accurately.
I will be installing a new rom over the coming weeks, just have no time right now. I just wanted to know if this seems to be a hardware problem or software.

Let me know how it goes. Sorry for the late response. I have been busy with school and work

I'm having this same issue with my Glide of 3 weeks. I remember having a similar problem several years ago - can't remember what phone it was - may have been the N900. I think that one was fixed by conditioning the battery. Where you drain it to 20% and then recharge several times. Does that technique sound familiar to anyone else?
I am stock GB/rooted and not opposed to flashing a new rom if that would help. Any suggestions on a minimal rom with working camera? (my one requirement)

Looks like it was a rom specific issue. More importantly, it was a battery drain. Something was causing my phone to hang and drain the battery overnight if I didn't leave it on charge. Not happening with CM10.1
Gingerbread on this phone has a lot more bugs than I normally like. I don't know how Samsung didn't catch these or found it ok to market the phone despite knowing these bugs exist. For example, stock music app periodically slows down and force closes for no reason.

My girlfriends phone is having this same issue after I re flashed the stock rom, rooted it, and installed twrp. Does anyone have any insight to this issue before she throws the phone against a wall?

Thank you! I was having this issue, and this helped me figure it out. My battery was definitely swollen, and after seeing this, I now notice it actually doesn't even sit flat in the battery compartment anymore. Luckily when I called AT+T they said it was still under warranty and sent me out a new battery with little hassle.

Got a issue and need a tissue

Right so had my nexus for a while and its been through pretty much every ROM and kernel combo there is without a issue.
Recently though its been having a lot of issues.
1: the phone works fine until around 30-40% then the phone screen keeps unlocking no reason. Give it a reboot / battery pull to stop it and when i switch it back on there is 5% battery. No reason.
2:it constantly says its charging even when it isn't. And when the battery drop happens I switch to air plane mode to listen to my music on the way from work and the battery goes up around 5%.
Things I have done to try and cure this:
1:Wiped the phone and reflashed including cache , delvik, and battery stats. With no result.
2:thought it may be corrupted media. Wiped the phone totally and removed everything from it to start from scratch . Still no banana.
3: upgraded to jb with bixies ROM , in case it was the ROM. Still happens.
If anyone could point me on the right direction of what I have to do yo cure this problem that would be great. As its making my phone usable only until it reaches 50% which as you would agree is not ideal in anyone's world.
Thanks in advance j

Either buy a new battery or the charging port in your GNex is fried.

Wow.. that is really weird well if that really is the root cause of the problem then I'd be amazed!

Hmm what about a replacement battery apk or something on those lines to reset all the battery stats and config. Really out of ideas what it is , ain't had this kind of problem before. Had most issues but this one is really odd and appears to not be fixable. I could unroot and send it back to Samsung but really CBA to do that and would rather try and fix it. Hmmm.....

Power Button??

So, my phone just rebooted out of the blue and the power button no longer works. sometimes it will get the power menu to come up, and then the phone will reboot if it is pressed again. I am running a VENUM hybrid ROM. I would not even know how to attempt a factory restore without an operable power button... anyone have any tips? I don't think Sprint would even fix this as I bought it from another Sprint customer

the battery moisture indicator is pink. i just cracked open the phone and I only see one indicator towards the bottom of the phone near the USB port, which is a fresh dry white. Don't think any moisture could have reached inside for whatever reason (not that it was wet recently...)
are there any others?
is there any way to power up the phone without the battery and test?

Mine does the same, it's started two months ago. It's gotten to the point where the phone reboots itself literally fifteen times a day. Very frustrating
Swyped from a Galaxy S2 on CM10

I guess I have the magic touch or some ****... just put her back together and it works like a charm I will be getting an extended battery I think. This battery is worn out and doesn't hold a strong charge.
I'm sorry to hear that multi, it's a true pain in the ass. I was just in touch with a Sprint rep and they said something about a $35 repair option?

My phone started doing that since yesterday.This is the second time it's happened.I'm thinking the power is stuck,cause when i try to turn off the phone.It always restarts itself.It's killing my battery.

This has been happening to me as well. It usually happens after chrome freezes on me tho. It did it for the first time not on a chrome page today. I think it's just the battery tho, it's been getting worse life lately. I ordered new Anker batteries so if it quits after that I'll keep everyone updated.

Something other than software is causing this to happen. Whether it be water damage, or damage from dropping.

[Q] Random power off issue

my epic 4g touch was on the cyanogenmod 10.1 wild for the night rom v. jan23v2. every time, if my phone were off a charger for 5-10 minutes the screen would flash to different brightness levels then turn off. it would do this every time since that rom. in order to fix the issue, i tried using sfhub's el29 root to go back to stock to try flashing the same updated rom. i was on el29 rooted and the issue still occured. i would have to plug it in for it to turn on again. is this a battery issue or is it something else? my battery is over a year old. any help would be appreciated. if you need more info, just ask

Amazon will have OEM batteries. Be careful though, some will label them like OEM but they are fake. You will probably be able to get a new one from Sprint or Samsung, though.

I've had good luck with cheap eBay ones for $3-$5. (~$10 for 2 + external charger, shipped from China)
Originally bought a cheap 1800mAh for my Epic, but kept it around and am using in my E4GT (when the orinal battery "puffed" and wouldn't hold much of a charge) Recently added a "2200mAh" one and external charger. It's a tiny bit thicker than my 1800, but still fits under the stock cover. I havent noticed the "2200" giving any better battery life than the "1800" - both work well and I've had no problems.

This issue is happening to me too but seems to occur when I'm downloading something like an MMS or app, or even an image intensive webpage. The screen flashes to different brightness levels and then the battery would suddenly "drain" to zero, where the software tells me it's at zero, but with a little extra charge and a reboot, the power level will be where it was before shutting down.
And none of this occurs while plugged in so I'm reasonably sure it's an old battery, I'd just like some confirmation. What gave it away though? The flashing screen thing had preceded a loss of signal so at first (and for about a week or so) I thought that was what it was until I found this thread.

Thanks.
When I went to get a new battery, the guy pulled the battery out and spun it on the counter. If it spins, it's expanded, and indicative of being on its last leg or already dead. Of course, you could also palpate the battery and you will feel the bulge but the spin test is simpler, definitive, and more entertaining. Just posting in case someone else runs into this problem or a similar battery problem and come across this thread - try the battery spin test.
