[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.

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

Q[How hot does your phone get]

My first Galaxy S3 went back due to excessive ink markings on the screen and since getting my replacement I have noticed it running hotter than I remember the first one being. The heat feels to be coming from the lower half of the screen / back of the phone.
I compared it to my friends phone and his gets just as hot. I am running FreeGS3 v0.1.0 and my friends was running stock - non rooted.
I ended up going to Sprint and the tech at the store replaced my phone with a new one out of the box and it is displaying the same behavior with temp.
I see no ill effects from this and am getting pretty good battery life for my usage, it is more of an annoyance for my phone to get so hot though. It seems a little warm for just browsing the web or FB on Wi-Fi so who knows.
It never seems to be the battery temp, but the CPU temp that climbs and is responsible for the heat.
I should point out that I had a Speck Candy Shell Case on the first phone, but that case has since been broke and returned. It is possible that my first phone got just as hot but somehow the dual layer design of the case disappated some of the heat, but I still feel it on the bottom half of the screen. My EVO LTE didn't get this hot in the few weeks I have it, and I have an Airave at home where it still heats up so I think we can rule out signal strength as a cause.
Anyone want to chime in with thoughts or suggestions?

Mine does that too, thought I was the only one.

Network related I think. Not necessarily signal strength but a poor data connection.mine gets hot as hell at the Bottem where the antenna is when my data is horrid.my roommates s2/e4gt Does the Same thing except at the top of the phone where the antenna is on that phone. Which would explain the battery life not being affected. The poorer the network performance the hotter it is. Sound familiar to anyone? Put the phone in airplane mode.and stress it in any way possible.overclock and run a benchmark while trying to play a game.what ever comes to mind.just leave in airplane mode and I bet it doesn't get nearly as hot as what your describing. I had a galaxy nexus on Verizon that rarely got hot. Where as my mother just got a sprint galaxy nexus which gets hotter than any phone I've ever felt but only with poor data speed as well. I've hit 120·F on my s3. I've seen her gnex hit around 140·F. So I'm blaming the network

Yeah I would buy that but my Epic Touch never got that hot plus I have an Airave at home. Doesn't heat up as much for me in Power Save mode with the CPU Limited. I think the CPU may be the culprit.

I'm leaning towards cpu as well, if I limit it seems not to get as hot

I flashed via CWM and no more issues with heat at all. I also saw a decent increase in battery life.

Idk if there's a bug, but check with betterbatterystats and see if gsiff_daemon is running at the top of the list... if it is, it's probably causing the battery to get hot, along with draining battery. You can fix it by using Root Explorer and renaming that file to gsiff_daemon.bak , it's in system/bin

I have had this problem when i switched to cm10 but my gs3 doesnt get nearly as hot on stock...

I'm having this issue as well and its kinda bothersome. I was going to post a new thread (glad s I searched first). I especially notice it when playing games, especially graphically intense ones like nova 3 or mass effect. The phone gets hot--real HOT. I'm coming from an evo 4g lte and it didnt get as hot. Love my s3 but I'm concerned I'm really gonna shorten its life by running so hot.

Can you guys give the tempuratures your phones are getting up to? Mine has yet to get over 106. My ET4G would get up to 116 if I was playing a game.

What r using to measure temp? Batt temp?

I've tried a few methods, the one in this thread and a few others and still a no go. I even went into root explorer and renamed giskk_daemon. I honestly think it's the menu bar on the white gs3. I had the blue one and had no problem until I recently exchanged it for the white one yesterday.

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.

This darn thing just got so hot it shut itself off and all I was doing was texting LOL!

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]Heat at upper right corner?

Hello,
I played a bit on my Nexus with wifi and was chatting on facebook for about an hour and after that my phone got really hot.
I sent it back to service, came back with changed mainboard but the same thing happens. Sometimes if I push my playtime it keeps slowing down, and getting hot really.
Can't fry a chicken on it, but it's around 60°C as I am assuming.
Is this thing normal?

What's ur ROM and Kernel?
