Evo fails in freezing temps!? Or is it something else?

Alright guys got a really weird issue and I would like to know if anyone has had this problem before. So I was at the gym for about 2 and a half hours tonight,and I left my phone out in my car. I live in the midwest so temps are starting to get pretty low. About 30 here tonight. Anyways I came back out when I was done and my phone would not turn on. When I plugged it in it showed no led. So after about 45 min I pulled out my battery and popped it back in and magically my phone came back on. I flashed the new ziggy kernel last night and I use os monitor to keep it set to smartass but I don't know why this happened? I guess im just puzzled is there an issue with the battery in really cold weather or did the kernel cause it? If you guys could give me some input I would appreciate it. Thanks.

I'm thinking its the battery since it is well known that batteries underperform under low temperatures.

Same Here...
I live in NYC, making a long story short...i left my phone exposed to the cold for a few hours and when i came back my phone wouldnt turn on either... no light, no charge, and after a bit in m pocket poof just started to work... I mean i know Everything has a Cold/hot temp, limit i think iPods are around 20 something degrees,,, i wasnt aware of the evo until now...

Thanks for sharing sir. It makes me feel a bit better that was my thought but I didn't know for sure ill have to research the battery itself and see what temp it can handle

Just overvolt it I wonder if we can do that via an app, AFAIK it requires a kernel level change

Well I am undervolting with ziggys new kernel and didn't seem to help. I think the battery is just a battery period. The cells go crazy at 32 degrees.

It's fairly well known that batteries don't do well in cold (thus why you see in car battery commercials "specially made to handle cold weather", etc. etc.) so that could be an explanation.
On a side note, LCD's don't do well either (think about it, Liquid Crystal Display). If you want an example, go in to Best Buy or something just after they open, while the building is still cold, and check out the LCD TV's; they'll all be lagging and fuzzy pictures.

I said overvolt not under. It would make it run hotter, so the temps wouldn't affect it so much. Put it in an inside jacket pocket, that tends to get my phone pretty hot on its own.

I live in Virginia and occasionally leave my phone on my car. Temperatures have been in the teens and single digits lately. No problems so far, but I'll probably be more cautious now. Hope it doesn't affect my battery in the long run.

Thats my fault, read your post quickly last night and didn't pay too much attention I guess I just saw "volt". Overvolt would not be a choice of mine though I would rather not risk frying my phone.

[Q] Temperature

Hi Folks.
Does anyone have any idea what a safe operating temperature for the Samsung Epic Touch 4G is?
I most recently have been using the usb to hdmi converter to play shows to my TV and then running a VNC Server on the phone so I can control the Epic from my laptop to pause, play, etc. while the phone is setting by the TV.
This works great, but with the video and the server running the Epic gets up to 42 to 46 degrees C.
I have felt phones get hotter, but I don't want to damage my phone either. It cooled down to 32 degrees C pretty fast after using it as a media center.
Any opinions or technical knowledge? I ran it for a few hours, and am hoping I did not cause any permanent damage.

I know epic 1 shut down at like 110° f. might be too low, but mime got so hot on halloween after using as projection for our haunted house. Bricked the phone until I factory reset it...played movie fine, just boot lopped.

I think I took the Touch to like 114F. I did not notice the phone misbehaving at all, and it cooled down fast enough. (Well not entirely true. It kinda froze up, but that happens everytime I unhook it from the TV, seems my ADW Launcher gets glitchy when using with TV, don't think related to heat.) I think the reason it really heated up was due to using as vnc server, would not even gain charge. Yesterday when I just streamed the video to the TV without vnc, it stayed charged and seemed cooler.
The phone you used for a projection, was it the Epic or the Epic Touch? And after doing the factory reset, did you notice any issues? Slower, freezing, etc.?

Just Bumping this...
Hoping to get some more incite into the Epic Touch temperature specifications.
Thanks in advance

Bump one more time. Anyone?

I think that the phone shuts down beforehand but it would be nice to know what that number is.

Thanks for the reply John.
I would think so too. Just curious as doing the streaming etc to the TV is very convenient but not worth damaging the phone. I really think its ok to do so though, the phone has been at 40-42C with normal use. Running a bit above that has not seemed to harm it.

I think I had a run in with a rogue app the other day. My battery was draining unusually fast and I plugged it in to charge, but it was charging very slowly and the temp got up to 120F according to the widget I'm using. I rebooted and everything has been fine since.
Sent from my SPH-D710 using Tapatalk

Often times (I mean, very often) when I go to grab and use my phone I can tell by touch that it's hot and check the battery temp - those times it's usually 106° F and higher. I could tell you now that seeing my temp at 110° to 115° F doesn't surprise me at all. What kills me is that most of these times I'm not actively doing anything with the phone - I've just pulled it out of my pocket and think, damn, it's hot again.
A couple of weeks ago I updated the Widget Locker app to the latest version to try out the Honeycomb and Ice Cream lock screens, so after updating I played around with it for a while. My phone started getting hot - as in HOTTER than I'm used to. I checked the temp and it was screaming hot at 122°. What's worse is that it kept getting hotter and when I checked my battery monitor app it was definitely Widget Locker that was driving it up there. I powered off, let the battery cool a bit then rebooted. I plugged in the phone to regain some charge and checked it a little while later to see it was really, really hot again. Now at some point it was so hot it would NOT charge - stating this explicitly. I pulled the battery to let it cool and tried again later. This happened about 3-4 times before I said screw it and uninstalled Widget Locker all together. Hasn't done that again since.
So, if it helps you at all, temps around 110° - 115° have been fine for me. Over 120° would start to concern me and I think it stops charging and gives you a warning at 130°.
I've attached some photos of that particular instance. The last photo shows my temp distribution... I'm assuming all the time, and it surprised me at being an avg of 88°.

Thanks Beans! That was very useful information. I feel mich better now. Thats to bad about Widget Locker. I have used that app on occasion. I have not had a problem yet with it getting to hot on its own. But if it does I will assume its a troublesome app. Thanks again!

I used to have a problem with Widget Locker in earlier versions but the updated versions have been much more battery friendly and my phone doesn't seem to get hot from it. I am using a custom slider that someone from XDA made though but I don't think that should matter

[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.
Cheers

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.

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

104 degrees Fahrenheit, thanks Samsung

so my phone is charging I get a phone call yep hot as he'll burning up... I look 104f yeah that's real hot couldn't even talk on the phone, phone lags as hell, the screen issues with the blur I mean come on Samsung I love you guys but you really messed up the phone, I loveeee. the camera on the phone its amazing but still not worth all this... and don't tell me a update would fix this, a Damn 670 phone this should not happen never happen on my note 2 which is faster, another feature Samsung forgot Sheat

You realize 104 F is not hot... at all.....
1) Laptops and have had electronic components built to withstand up to 100 CELSIUS for years. I'm sure your phone can handle 40.
2) If you can't talk on the phone because a little warmth is too much for your sensitive skin move the **** to Alaska because 104 is not hot by any stretch of the imagination.
3) My phone has no lag.... at all, so I don't know what you're speaking of. I can play NFS:MW for an hour, switch to Eufloria HD for another, then hit up GTA:VC for an hour with absolutely no problems. I can also scroll through the drawer faster than my S3 could respond, so it is much more responsive. Maybe you got a defective unit or you messed it up somewhere rooting or flashing roms or poking around where you shouldn't have... I mean based just by your grammar you're not that smart of a person, so I'd say user error is MUCH more likely.
4) If by the blur you mean the purple when you're in the settings, well yes. You've got me there. That is a minor bug that needs to be addressed, and will. The phone has been out for like 11 days bro, give them a ****ing minute.
5) No, sir, your Note 2 is not faster. Yes, it has a larger screen and slightly better battery life, but faster? No. Run a CPU and GPU benchmark and try to tell me its faster.
Give them some time to work out the kinks in the programming. This is how electronics work, nothing is ever going to be perfect when its being produced by the millions on a short time frame with 6 different versions for different countries with different hardware and 10000 different carriers trying to poke around and make their own adjustments to the software.
TL;DR: Stop crying, you're embarrassing yourself.

hi you

I hate when people say use benchmark look which is faster... man everyday use is what matter, when I'm playing games and my note 2 runs them smooth and my S4 runs them choppy there is an issue I'm sorry there just is. Now for 104 degrees being not too hot, wow really its beyond hot for a phone to hit, don't give me the whole laptop crap this is a phone that people use to make phone calls and the screen and the back just feels way way too hot. Just use the speakerphone what are we Apple "You're holding it wrong" come on guys give me a break a 670$ phone should not have all of this stuff going on. Then you're telling me oh download an app to fix the screen issues -.- , you guys may think this is over the top i don't think so when you buy something so expensive and it works so iffy, don't get me started on Shealth love it but keep restarting your steps all the time ... might as well call it Srestart ..... oh samsung i love you but you're killing me with this phone. I'm getting a replacement on monday I'll let you guys know how that one is hope its 100X better....

No, 104F is not too hot for a phone to hit while charging and being used. You have heat from the battery while charging and heat from the processor while using, add any case you might have put on there trapping the heat and it is still well withing acceptable parameters. In Florida ambient temperature reaches that through most of the summer.
And if this thread continues to be a flame/troll fest it will be closed.

Like everyone else had said, I dont think thats very hot. Thats around where mine is

104° F is actually cool for a phone th that's charging and in a call. If the device is lagging out on you just return it if a reset doesn't fix the issue.

I actually had this same issue on a white 16gb s4. Phone was powered off while charging over night. Upon powering it on the internal thermometer also read 104F. I suspect it was much hotter, given I have hot spots on my laptop case that reach that temp as verified by a thermal camera. This felt much hotter, though I didn't have the tools on hand to verify.

I've heard a few people complain about their devices getting too hot, but most of them have had the white version. Is that what you guys have had? I have the black one and haven't experienced this issue at all. It does get a little warm when charging, but other than that, no issues here

Im shocked that no one has asked this. But...

Well I'm in Florida so whenever I'm inside it's like a warming pad against the AC. When I'm outside I don't care because it's not getting any hotter than the air already is. Sound logic.
You do realize I was being sarcastic right? Regardless, that's neither here nor there. You can't make a thread and be like "Damn samsung my phone hits 104 F when I'm charging and talking on the phone!!!!111oneone"
That's not hot. Especially for a phone that's charging while doing anything, or using mobile data in any way, or playing games. When it hit's 60-70 celsius start complaining about overheating problems/return it. When your phone hits 100 degrees Celsius start worrying about the internals frying. Anything less than that stop complaining. It's a ****ing quad core computer that fits in your hand and is slimmer than a BIC lighter. Of course it's going to get warm. If you didn't realize that when you bought it you shouldn't be paying 650 bucks for anything because you're too stupid to have 650 bucks to spend.
For the last time, that's not hot at all. This thread is pointless. I'm done with it.

[Q] lg g pad over heating

Recently I bought the device ,it worked great at first how ever now it tends to heat up too much and because of that the device writes a message in which registered over heat turning off Because of extreme Temperature the device turns off.
does this problem happens to you too ?

This is the first I've heard of it but you obviously have to return it for abother pad. Even with the aluminum back mine only gets warm at the most

it happens only when i am trying to benchmark it , have u tried it and what version is your device bcz i think its a software problem .

I've only noticed the device getting hot when I benchmarked it over and over again to sort of stress test it. From regular use it does get warm (all devices do, including cell phones) but I've never had overheating problems.

Um, don't do that then?

Mine has done this before while playing riptide. I had my brightness at 95% and it turned it down and had a toast warning. I really think it is the design of the tablet and this can happen if you push the tablet hard at full brightness. I haven't seen it since. This was back in December so I wouldn't be too concerned If it doesn't become a normal occurrence. I have owned many android tablets and this one definitely runs the hottest.

I have the same issues guys... this tablet has design issues. If you charge while using WIFI boom u got over heating. also without charging normal usage will trigger overheating i have recorded temp going more than 70 Degrees until it shuts by itself.
I had replaced my tab once but the new unit has the same issue.!
Any fixes so far?

....same to me.
any suggestions?
