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.

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.

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.

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.

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.

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

104 degrees Fahrenheit, thanks Samsung

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.

Well the headline gives it away guys!! OK so, I dropped my phone last week(I had a case on it, but its a cheap case off of Amazon)! Nothing happened to the screen, but the power button is now way more sensitive than it should be, and my E4GT heats up a lot quicker than it normally should! I have the Qcell battery! Is it the battery or the phone! Please let me know! Thanks again for all of your help!!
Sent from my SPH-D710 using xda premium

Where is the heat coming from? The bottom of the phone or top? If its the bottom I would say it might be the battery. If its the top I would say its the cpu. Are you overclocking? Are you playing any intensive games? Do you have an app that can read the temp of the battery?

It's coming from the middle of the phone. I have an app telling me the temperature of the phone! So maybe its both!! I just barely got the battery on March 25, 2013! It's gone that quickly!

Ohh I fixed this problem. I ordered a hyperbion battery and used it for a couple weeks and realized the qcell is farrrr better. So I put the qcell in the fridge after charging it over night one time and left it in there and came back about 1-1 1/2 weeks later and swapped the batteries in the fridge. That seemed to fix it so I used the qcell until school started 2 weeks later. And the fridge made the hyperbion better than when I bought it

On release I got my D710 from Sprint and it was overheating too. It was super hot especially when I charged the phone without a battery cover. It literally almost burned me so I exchanged it at Sprint a few days after and they even hooked me up with a free oem battery. I think there's a bad batch of overheating S2s cause Sprint will replace it super fast if you tell them it's overheating too dangerous temps. That's how I got them to replace my phone when my power button broke. To top it off it was within warranty and I had insurance and they didn't want to replace because of power button issue until I said it was overheating lol.

GSIV gets warm while charging - SD Card?

I noticed my GSIV was getting warm while charging... I put it side by side with my girls GSIII, and hers was nice and cool.
I decided to take out the SD Card, and viola! My phone is cold again.
I'm thinking this could be cause by the SD Card itself.
Anyone else has this issue while charging?
