[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.

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.

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.

Ever drop your phone? Do you use the power button a lot?
Something other than software is causing this to happen. Whether it be water damage, or damage from dropping.

Normal for S3 to get warm on bottom of screen and back of phone?

This is my 2nd S3. First ones home button stuck down and wouldn't come back up. That phone never got warm at all. I was wondering if this is a normal occurance on the S3. My phone now gets rather warm while surfing the net and checking email for about 10 minutes at a time. brightness is at auto (as was the first one) and all settings are as the first one was. Just wondering if I should do a warranty swap since I am now over my 30 day return mark.
Thank you all
AJ

Mine does the same thing. Most phones will get somewhat warm with heavy use, the S3 seems a little more susceptible to it, maybe because of how it's designed.

Mine will get warm as well. I haven't had it get hot except for when I use it for GPS in my car which is understandable considering I turn brightness all the way up with gps/data/wifi and have it charging at the same time.

Yep perdectly said thats the only time mine has gotten overly hot!

mine gets warm, never hot. I do notice that on this one it is, as I said, towards the bottom. The first one I had never got warm at all. I'm hoping I won't have to go return this one warranty wise. I love the phone. LOL. When I called ATT to ask them the question they said No it's not normal and to return it, then asked if I have heard about the Iphone 5 coming out LOL.

The chipset is in the bottom area underneath the simcard/sdcard slots.its normal for it to warm up.However if its superhot then no......usually massive heat will damage sone sdcards happens all the time at my store.

I have one day left actually on my 30 day returns policy. Should I utilitze this and get a new one? If so does the white or blue make a difference? I hate returning phones!!!
(Update)
This darn thing just got so hot it shut itself off and all I was doing was texting LOL!
AJ

Mine gets warm when charging or both GPS/DATA are on.
Once, I got a "system is too hot" warning when I left it charging under a pillow.
I think it depends on how much you use it...some days, when I play games or watch Netflix for 20 minutes straight, it gets a little warm.

If it legitimately shut itself off while you were just texting because of how hot it got. Return it now.
That isn't normal at all.

[Q] HELP! phone crashes/hangs-restarts with dead battery

Hi everyone, I am having an unusual problem. I was running re-calked fi29 and when I would be using my phone somewhere between 50-80% battery it would freeze and reset the phone (or I would have to remove the battery). Upon restarting, my battery will be less than 12% then will immediately shut off and won't restart until I put it on the charger (when I do it still shows battery above 50%>. I always flash el29 before flashing roms, reset battery stats, and caulkin format all. I switched to Phantom rom and I continue to have the issue. This is happening every day and has left me up **** Creek since I am on vacation and using maps. Any suggestions? Thanks.

Also, upon plunging the phone in, it works ok, doesn't crash

Are you by chance under volting at all?

Is ur battery bulging out of the battery door?
Sent from my SPH-D710 using xda app-developers app

No to both questions.

Put your battery on a flat surface, smooth table, countertops, desk, etc and spin it, if it spins like a top its starting to bulge. The symptoms you're describing are those of a bad/bulging battery. Oddly enough it can be bulging but still test good in the machine at the repair center and they will do the spin test to confirm bulging and swap the battery out(as long as they have one in stock) even if it tests good. I've been having the same issue with mine and waiting for the corporate store to get some more batteries in so i can get mine swapped for free. If they don't get any soon I'm just gonna go the Samsung route and get it swapped thru them and just buy a cheap replacement to use while I wait for Samsung to receive my bad one and ship a new one out.

Damn I'm having similar issues, but my phone will randomly reset without freezing. It usually happens when I'm in the middle of something on the phone too. I flashed 3 different roms, incase it was a rom incompatibility issue but no dice.
The battery thing is interesting though, I also carry a spare Samsung battery with me and the phone will still restart with either one in. Not sure what the issue is since this recently started happening.
