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

I've had 2 replacement phones in my 1st month of having a Gnex.
Just then I had a random turn off. Normal or not?? No rooting, no unlocking fully stock 4.0.2. Wtf?? I just thought yay!, everything is going to OK then bang. Not cool. Might be normal but I doubt it...
Thanks guys.

This happened to me last night.
I wasn't using the phone, it was just on the table charging.
Not sure what's up.
Do we have faulty units?
Sent from my Galaxy Nexus using XDA App
I guess it depends on how often it is happening.
I've had my phone for two months now and I believe this is the second time it happened.
As long as it doesn't happen too often and not during a ROM flash, I can live with it.
Yeah, that's the problem though isn't it. Random. It could be when your flashing a rom, or in a phone call. That'd be ****.
I dunno, why do these things happen?
Don't Google test things? Its not real stable is it. There should never be any problems if its a full release.

Nah not at all. Its happened twice since in had it. Once when the battery was at like 6% on its first run down of the battery when I got it. Then on it's first charge. It was at about 80% and I was just swiping left and right and I think bringing the notification drawer down (which doesn't work sometimes, I have another thread on that) and it just turned off. I pressed the power button a few times and it finally turned on with a 10% ish battery drop. That's it though, not again yet. May of been a battery conditioning thing.

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
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,

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.
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.

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'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.
