Epic gets very hot when I use 3G or 4G

My epic gets very hot when I use 3G or 4G, It is hot to the touch and situated at the top of the phone near the camera.I have 4 bars and no signal problems whatsoever. Does anyone else have this.
Thanks

Yeah. It'll do that. Especially if you use the connection for extended periods of time. It's nothing to worry about.

Mine doesnt get hot like at all.
The only time is gets hot is if im charging while playing a game or charging while it on like leather furniture or cloth. Other wise those are the only incidents i have to see where it gets hot.

Anyone else have anything to share?
Thanks

Download an app like battery indicator or spare parts and tell us how hot it gets. These apps have a temperature indicator on them. See exactly how hot it gets. Mine only gets hot when it's charging and I'm running high CPU things on it but I've never felt it get hot like you described off the charger.

I just checked today it was 42 Degrees Celsius. What are you getting?

I just bought one of these phone. I have also had the issue with the phone getting hot while on 3g. Streaming audio it gets pretty hot on the top half of the phone. The battery doesnt get hot at all. If i use netflix, it get very hot on 3g but doesnt while on wifi. Could this just be an issue with the radio on the phone getting hot?

The processor is working harder to pull the data while on 3g and that is why its getting hot.. imo if its not getting above 115 degrees really nothing to worry about... just don't use it for hours on end while its that hot. Also flipping the phone onto the screen while its streaming seems to help with the temperature also...

Getting hot

Anyone else's getting very hot. I already returned two rezounds for getting up to 150now my nex is up to 111 right now and all I was doing was playing around on Facebook. Most of the heat feels like it is on the top half of the phone and the screen gets extremely hot

Is your brightness up high? And also are you charging it while playing on it

Charging now wasn't then and yeah I keep brightness up otherwise the screen is way too grainy. You should be able to use your screens top levels without scolding your fingers lol just curious if this is a common thing or If I have to yet again get another phone

My phone heats up on the top part like yours but mainly when I use it while it charges or if I keep the screen awake for about 20-30+ min straight.
Edit: just like your laptop or TV or psp or any other electronic device lol

Not seen any issues on mine so far and it doesn't get as hot as my iPhone 4S when that is charging and/or using bluetooth for making calls.

yeh my phone gets quite warm also , crazy thing is when it gets warm im sure it affects the colour temp of the screen.

Mine gets hots quickly when I play Riptide a lot.

I noticed this too, but. I don't feel it since its just the top half and my hands are gripping the bottom half. I do feel it when I stick it in my pocket and my thigh gets really warm.

Mine heats up at the top back only when I'm using mobile data to do stuff. But I can use wifi all day with top brightness with no overheat. Stupid.

like right now. I literally just turned my phone on 5 minutes ago and am on wifi and I can feel the top getting hot

when I got my phone a few weeks ago (GSM 4.0.1) my phone easily warms up especially at the back near the camera area. After manually updating to 4.0.2, I really noticed it was gone. Now even I am watching youtube videos for more than 20-30mins my phone doesn't warm up even a bit unlike before i got it on stock 4.0.1 in which just turning on a wifi connection and gps warms the back of my nexus without running an app.

Define overheating. Because i think the phone does quite well for how much horsepower is under the hood. Mine gets warm doing this, that and the other. The only time i was seriously concerned was watching a netflix movie over mhl and really i was really only concerned about the battery temp than the phone. The phone and its components are a big step up from phones 3 years ago. People used to whine about phones getting warm when 3g heated them up and 3g was becoming the norm. Fast forward to today and there are more powerful components packed into less space, and less ventilated at that. If you dont like your phone warming up get a dumbphone and be done with it. I think the nexus and most other smartphones do quite well. And this was before i undervolted it. I can only imagine how many useless threads will pop up about heat when quad cores come out. Personally when i upgrade next, hopefully two years from now and not the annual phone i am accustomed to, i hope a dual core cpu and gpu at 28nm or less will be sufficient and be well within the thermal windows and limits for how powerful these pocket size devices have become and dramatically changed our social lives.
Crazy world, ay?

mine gets hot up top on my ear when I'm on a call. I found at least by switching to the new 4.0.3 radio and doing a combination of over clocking + under volting it doesn't get nearly as hot anymore.

I'm talking when my battery temp is 111° and the top of it feels much much hotter than that. I'm on 4.0.2 I understand the phones will get warm but they shouldn't from ten minutes of Facebook. If I was watching Netflix using my GPS and doing so over 4G then yeah scold my hand I get that but not frickin Facebook or internet browsing or anything like that. I really like the phone and ill be keeping it but apparently won't be playing many games lol

I use a SetCPU profile to peg back the processor to ~700mhz when the temp gets over 40c

Whoa, it's overheating? You might have a defective phone. Mine gets pretty hot but the heat hasn't led to any stability issues or damage like yours. (Note: It's not overheating if there's no damage, so I'm assuming by your text that your phone got damaged)

I don't think his phone got damaged, I think it's just hot.
Mine gets pretty hot but the operation of the phone has been fine. It sounds like all of the phones operate basically identical to this.

No not damaged. I leave it alone once it gets real hot. I've turn down my brightness to help prevent it a little. Def doesn't look as good lol

If it's just getting hot it's not overheating.

Tmobile version overheating

I've been reading the other thread about overheating of the S4. Mine will get warm to hot just by downloading from the Play Store and playing withe the menu. I tried a factory reset, microsd reformat, etc.
Does anyone else with the tmobile version notice the phone getting hot?

I have tmobile version and it runs really cool

Sure - any huge data usage, (especially with 3g/4g/lte) will cause the phone to heat up in the cpu area - this can be coupled with high graphics usage, and/or high ram usage -
electricity generates heat as a waste product - it wont get too hot, but it will heat up.
My gs2 would occasionally get so hot i didn't want to hold it or let it sit in my pocket
My new gs4 got plenty warm when redownloading my podcasts, and durring the first google device restore.

But I don't even get edge where I live. I've been using wifi and it overheats in like 10 minutes. I hope it's just a software issue, if not ill get a replacement. I just wanted see if its just me.

For me so far, the only time it is noticeably warm is when I use the camera for an extended period of time. Haven't played any intense games on there though like NFS.

I find that my microsd card get hot when accessed a lot, but that's not new, same as in my S3.

Mine is hot too. I haven't done anything though.

I believe there is firmware update that is compatible with the I9505 Tmo variant. You may want to do some searching and check it out.
The main S4 forum is a good place to start.
http://forum.xda-developers.com/forumdisplay.php?f=2162

Heat is not the same thing as over-heating. These chips have a maximum operating temperature rating of upwards of 70c. There are a myriad of reasons why any two devices would operate at higher or lower temperatures including ambient temperature, radio actions (high-throughput or low signal recovery), and of course running processes. There will always be people who think their phone is "too hot" since it is a purely subjective claim.

yeah honestly is at 40c and thats beyond hot!!

Yep, mine heats up on the top back of the phone. But it doesn't overheat when I'm on the phone though. I talked for over two hours and the phone stayed cold. But if I play around with menu and installing apps, it gets noticeably warm. I used S2 for two years and didn't remember it getting this warm.

mine heats up probably i am using 4g data and voip app to call people
but it heats up top Samsung name area like u can feel it in like 10m lol

Like others mine heats up at the top back at times but never to a serious, uncomfortable degree. Pretty sure my Blaze would get hotter at times from less taxing usage.

So hopefully this is just software related issues and not hardware.....

Try turning down the brightness of the screen, I saw some reviews say the density of the screen adds majorly to the heat.

I have to wait 20 days to exchange it. I could return it but my micro SIM card doesn't work on the S2.
Anyway, I just received an OTA update.....

I've used my micro sim in a GS2, a MyTouch slide and a G1. It will fit, just line up the 3 pins to the 3 plates on the sim and it will work

OGP (ATT E980) issues.

So I have had this phone for about over a month and I just love it. Here are two issues I have encountered so far. I don't know if it is the phone or a software issue:
1. The signal sometimes drops to 4G (not LTE) or Edge when LTE signal is weak but my wife's S4 holds on to one or two bars of LTE signal in the same spot. And then after I get an area where the LTE is supposed to be strong, the phone still says 4G or Edge. I can only get back to LTE if I toggle plane mode on and off. I actually tested the speeds to see if the S4's LTE signal is real. The S4 gives about 9 Mbps download and it shows LTE in speedtest app. While the OGP gives about 3Mbps download and it says Cell in the speedtest app. I hope this is a software issue and will be cleared when we receive an update.
2. The other thing just happened to me once yesterday. I unplugged my phone from the charger in the morning and played some songs via TTpod in my car. Took a few photos afterwards. Then the phone started to get warm in the lower half where you palm would usually hold it. The battery dropped at about 4-5 percent per hour (normally in idle it is less than 1 percent per hour drop). I tried stopping any unimportant processes that didn't help. I tried turning off my phone for 10 min and turning back on. It didn't help. I thought it might be the TTpod even though I had been using it for quite a while without a problem. I uninstalled it. Problem persisted. I basically gave up and let the phone sit in my pocket. The heating up gradually stopped after maybe a couple of hours. It haven't happened again since then. When I checked my battery status during the heating up though, it said the screen used most battery (however the on time was only about 9 min). I wish I had a screenshot or something.
Just want to know if some one also has experienced the same issues. Maybe it was just bad luck?
Nevertheless, it is a great phone. I hope we will get the 4.3 update and all the problems will be gone.

I work with a guy that has a GS4 and my LTE is way faster then his. We are both on the same network,and did a speed test at work the other day he only hit like 6 megs and I hit like 24... my other coworker has a note 2 and he downloads between 15 to 19 MEGS...
When the f*ck did we get ice cream??

Question Random overheating with Pixel 6 pro

I have an unlocked P6P on the Tmobile network. I noticed that this phone gets HOT under normal use. During setup I used it without a case because I didn't have one yet and it got really hot. I understand that it could be hot because it is doing a lot of things at the same time.
The next day after everything was setup and installed I noticed that it got pretty hot under normal use, I even turned down the brightness of the screen. This is just bowering the web, shopping on amazon and other random stuff. The thing that is kinda weird was I let the phone cool down before I played some game on it. Mario Kart go and clash royal for about 30 minute and the phone didn't get hot. It does NOT get hot charging so I am guessing it's not the battery.
The two previous phone that I had OnePlus 7 Pro and OnePlus 5, I never had any issue with it overheating even underload.
Anyone else have issue with the phone overheating?

Nope.
Are you in a 5G area? (cuz I am not).
It seems that most problems with heat/battery life come from 5G, if the reports are true.

Yes I am. Noticed that I got the 5g UC icon and the speed is crazy fast.
Even though I am on 5g I was at home with my wifi when the phone was heating up

Your phone will connect to both wifi and 5g, try at home to turn off 5g and use wifi and 4g and see if the problem. Persists

I have had a similar experience with my P6P. Just browsing the web is get really hot and drains the battery. Mine also gets hot while charging. Today on the drive home I had navigation on while charging and in 25 minute drive it only charged 2% due to throttling bc of heat. I have 5g disabled since day 2 with phone. I also have 30w car charger capable of 3800ma charging current. This is with adaptive battery on as well. Like OP, I never had heat issues with any OP phones.

Weird, I'm not getting overheating at all (in the UK). 5g is maybe slightly warmer it's not that bad.

I also never experienced overheating, been using Pixel 6 Pro since 27.10. I did notice the first day when setting up the device that it got a little warm, but that was neither "hot" nor "overheating". It simply felt warm.
I guess it has something to do with US 5G networks, since I've not yet seen someone from Europe complaining about overheating.
I should note that there is no 5G in my area available, so my phone has always been using 4G.

Yeah, first day (Tuesday of release) it was quite toasty after I set it up but after the update and day to day I don't get any heat or anything. I live in a 5g area and it does get warmer but not extreme I don't think.

Mine does the exact same thing doesn't matter if i'm on wifi or 5G with strong signals.
Also Unlocked, but on Vz network.
I would be browsing this forum and feel it start heating up randomly.
Do you also have horrible battery life?
It seems like some of the devices have these same issues, and others do not.

Mine didn't get warm/hot at all before I unlocked and rooted. I had it locked for nearly two weeks, no troubles. Now I'm experiencing this as well. Web browsing it got warm. Doing some other things today like installing a couple magisk modules, some other random things, it got somewhat warm. Not sure what's going on? I'm only on LTE where I work. Also, I've been on 5G and no issues. I wonder if something used for root, one of my root apps could be doing it?

I honestly think this is just a rebranded exynos chip, it just overheats at the slightest thing, if they can't fix the heating issues then it's defo just an exynos chip.... Which is poor

Don't give Samsung all the credit, Google is capable of creating an inefficient chip on their own, lol. Using 2 year old core modules was Googles decision, so it's not just the evil exynos at work^^

I can't remember ever thinking to myself that my P6P is hot or even kinda warm. Even when playing a few space shooter games while charging cord is plugged in.
Even watching a college football game for an hour it never got hot...
