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.

Galaxy Nexus Overheating

So I just got the Galaxy Nexus (upgraded from the Nexus S) and just after the first day of use (no heavy workload, wifi or GPS) this thing became painfully hot. We're talking touch it to your skin and *ouch* hot. Strangely the massive heat output seems to be limited to just the top quarter of the device. Also note that it takes only about 10min until it reaches 'unusable' status.
Does anyone else have experience with this problem? Admittedly I was warned by the provider I got it from that they had had feedback from customers about it's excessive heat output and other people I know have also commented to the same affect. But I never thought it would be quite this bad. I could fry an egg on this thing. Considering my Nexus S never had this issue - this is disappointing. Are we talking hardware design fail? Or perhaps a bad batch in my country?
If this was an iPhone they'd be headlines going on about 'heat-gate' and Larry Page coming out saying that we're 'cooling it wrong' lol

the nexus does get abit hot around the camera area, but it shouldnt be THAT hot lol.. what are the ambient tempreatures around where you're using the phone?

Not that hot - maybe 20-25c

Perhaps monitor battery temp with an app, it won't give you a precise indication of your processor temp, but there should be a correlation. The phone does get warm around the camera area, but never painfully so (for me). Was your AOS usage abnormally high?

I think the OP is overreacting just a little, if it burned you then the phone would have melted
Anyways, its perfectly normal. the OMAP4 chipset runs really hot, I read somewhere that it operates normally between 85-105 degrees Fahrenheit.
Here it says that the OMAP4 platform has a temperature range of -40° to 85°C. I think thats overstating it, but its all there

Well let me put it this way. It's hot enough for me to consider claiming on warranty. No phone should generate that much heat right next to your head/ear. That's unusable in real terms (at least with this particular one). And i've had my fair share of android phones in the past to compare...

The Tegra2 chipset runs VERY hot when overclocked as well, I've had hot experiences on both my Galaxy Tab 10.1 and my G2x, and I can also say that the OMAP4 runs hotter than that! Just offering opinion is all, it's perfectly normal for it to be running extra hot, and it happens fairly quickly.
I completely agree with you that the phone does get abnormally hot, but then again, from my experience, so does the RAZR with a sister chip in it.

Android 4.0.1, stock Nexus Galaxy, going on 2 weeks. It's in an otterbox defender case, after 1.5 hours of running video it's warm in my hands, but that's under constant workload that nearly drained the whole battery. In other words during normal operation I am not finding the serious problem you are describing. Empathy out to you.

What temps we're talking about? Mine stays at +36C +38C while browsing web/watching youtube and gets a bit (around +41C) hotter when playing games. And these temps are far from hot-to-touch.

Sometimes my GN becomes really hot too. It also happens when i'm watching hd video for a half an hour or more. Then it turns terribly hot.

mine goes to 48C and then it starts lagging like hell

Mine gets warm around the camera and earpiece. It's pretty normal, I'd say.

There are multiple threads on this, but I'll say what I've said before: it's a dual core device, it runs hot, it's not "overheating" unless your phone is crashing, shutting down, or otherwise obviously malfunctioning in some way other than getting hot.
What do you mean by "it reaches 'unusable' status" though? Are you just afraid of using it because it seems hot? Mine gets quite hot when I use it heavily...have kept it going for several hours in this state (while plugged in) with no other issues.

Mine gets hot in the same area, but it has never been that hot, just warm. My OG Droid was OCd to 1.3ghz and that literally reached 150+ degrees F quite a few times and is still fine to this day. The OMAP SoCs seem to run a bit hotter than others, but they can definitely handle the heat.

Basically out of the many smart phones i've had in the past. This is the first that I would say I would refuse to hold it up next to my ear due to the excessive heat. It's bad enough just holding it landscape to type on let alone sticking next to my head. It's really annoying considering how otherwise the interface and physical design of the device is better then anything else i've seen on the market.
I think i'm going to get one of those laser thermometers to find just what the temp on the surface of this thing actually is.

It's hot on the back of the phone like other uses have said, not the front where your ear would be (unless it is which is an entirely different problem). Plus, when your phone reaches those temps through extraneous use (videos, games), you normally wouldn't be putting it near your ear anyways. I don't see this as a huge issue. If you do something taxing, much like a computer, expect the phone to work a little bit harder and hotter.
Oh and I doubt it's hot enough to fry an egg. You would smell the plastic melt first.

I've had once when my GNex was really hot. It was when I try factory reset many times since there was a bug that factory reset does nothing in a custom rom. But I didn't know at that time. I tried reset, flash rom, reset, etc. My GNes ended up really hot.

The only time my galaxy nexus got really hot was when I was switching kernels every 2-3 days, and one kernel (I think it was one of Franco's earlier builds) made it run hot even when I wasn't using the phone that intensely. Changed the kernel, and it's never been hot since (I play games, listen to music, browse web, push notifications, etc.) I don't do much video/HD streaming though...

I have been getting that too. Around the earpiece gets warm when only slightly used. Also, I can hear a faint buzzing humming sound from there. Open the back cover..can hear it from the camera too. Is something wrong with my phone

Brand new Nitro getting really hot

This thing gets hot. I've had an HTC Hero, LG Optimus, and HTC Evo 4G before (all on Sprint) and none of them got hot unless I was charging it and talking on the phone.
But this Nitro gets hot after just a minute of browsing the internet, or even just playing with the settings (ie not using the radio). It's not the battery getting hot either. It's up on top of the phone around the camera. I have no idea what's causing it.
Anyone else experiencing this?

Yeah.. that happens to all of us. Under-volting helps a bit.

Welcome to the hell that is the Nitro's constant overheating!

Well I'm glad I'm not the only one experiencing it! lol
Maybe I won't notice it so much when my Body Glove comes in today.

Depending on how new your phone is, if you can still return it I would honestly suggest doing that. This phone WAS good when it was first released, but the other offerings on the market now (HTC one X, galaxy S 3, Galaxy Note, Galaxy Nexus) blow it away.
The screen is awesome, but you can't only base a phone's performance on it's screen quality.

The bodyglove will get hot as well. Only happens to mine once in a while when I'm using it heavily.

It's a software issue I believe. If after using ur browser of the Facebook app and hit home then open the stock application manager u will see the browser can use up to 28% and Facebook spiking to 70% CPU usage and since the small logic board holding the core CPU is at the top of the phone it can cause the overheating in that area

Gotcha.
Does anyone know if CM9 fixes this? Or maybe the ICS update will?

The phone will always get hot if you are heavily using the CPU, regardless of what ROM you're using. That is considered normal. It doesn't mean your phone or ROM is defective UNLESS your phone is rebooting when it gets too hot (i.e., it's overheating).
The Nitro is just designed with a CPU that gets hotter than most.

mine doesn't get hot. warm yes. hot, not in the slightest.

Mine starts to get hot after about 10 minutes on a voice call. After about 20 minutes I have to go to speaker phone because it's just uncomfortable to have next to my ear. I'm hoping that this is a software issue and that it gets resolved with the official ICS release.

my lg lu6200 also gets very hot while playing games but stays at normal temperature while internet browsing

? snapdragon is in alot of phones wtf are u talking about.
mine only got "hot" one time, when i left it in the direct sunlight in the car with the windows up and was shopping for 30 min or so, when i came back it was hot, i left it on mistake.
other than that i've only had it very warm a few times, when charging while doing heavy usage, this is because your battery gets real hot, you can get widgets that give you the temperature of your battery, which is more likely to overheat than your cpu, unless your cpu is overclocked too much.
if your phone is getting warm brand new, your battery is getting broken in, don't panic, keep an eye on it though and it should break in over time. my battery got warm alot faster when it was new, and it didn't get as much lifespan as it does now, as far as i know this is normal.

Extremely high phone temp!

Does anyone have issues with your SGSII T989 phones having extremely high temps?
I get it when using the GPS, charging the phone while i'm talking on the phone, and doing a few other activities. It did not do this on my first purchase of the phone and i'm a bit weary of the temps as sometiems it gets quite warm!
Currently I'm on O.E. SGS II Rom w/ root, that's about it! No OC no mods or anything of that sort. (Just CWM and Root).
Any tips would be greatly appreciated, as this heat as caused me from using my phone each day more and more.
P.S. I WAS on Juggernaut Rom and then flashed back to Stock, and it was having this heating issue then, should i try to do a complete 100% wipe like on one of the development threads and start from scratch like I just got the phone from the factory again? I wiped my system using Odin and it seems to of kept my old programs, no information like games and etc. was kept however, does anyone think that might be the problem? Once again thanks!

If you are rooted you might want to try a different kernel and maybe SetCPU. I had some overheating/temp issues a while back and after I lowered my CPU a bit and set it to an Ondemand state with a profile for screen off running CPU very low when not actively in use it seemed to fix the problem.. Btw SetCPU is free for XDA users, there is a thread somewhere in the Android Hacking Apps forum..

Edit: I thought it was free to xda users, I checked and cant find the thread, maybe I was wrong or they changed it..

I'm on the stock kernal, I was on the modified 1.7ghz kernal before i believe, as I could overclock over that, but i just recently stopped that and went back to stock. I was and still am expecting the phone to malfunction on me sometime soon lol. It's been a really reliable phone so far! My G1 and Mytouch 3G slide (gf's phone) took soo many dumps on me while I used it. Each of those phones were probably sent back 5-8 times and they were kept completely stock for a while!
Back on subject though. Any kernals that go well with the factory rom? I don't favor any aftermarket roms right now as they're not stable enough for my usage IMO.

I have heat problems but I've always had the stock kernel...

Undervolt at the stock clock if you want to lower temps. However, charging will always increase heat especially if you are using the phone at the same time, and depending on ambient temps.

Dude my moms sgsII literally got fried because it heated up once. She was using her phone normally and all of a sudden it started heating up. She kept using it and the next day the phone won't turn on, charge or get into download mode. It looked like what a hard brick would look like. So I just returned it for a HTC one S.
Btw she was on full stock.
My phone heats up a lot because I'm down south with 90-95 degree temps and I keep phone in the car dock by the windshield but it never failed on me.
Sent from my SGH-T989 using XDA

I thought it was a well fixable issue. Guess not? lol... Either way, everytime my batt temps rise, i notice i get 40-45C and i start to get worried. So if i'm in a car, i'd just put it next to the AC vent while the car's running and temps get down to about 25C and i'm good again. I just don't feel comfortable with the phone anymore like I use to. It never did this before, why now??

I have an app that warns when it goes over 40 and it happens daily. I was downloading torrents one time and it keeps the screen active while downloading and the thing got like 62 celsius before I realized what happened. It almost burnt my hand lol. if your ever in sunlight or palming the phone while using gps on 4g.
overheating is very common with this phone I wouldn't worrie about it to much it is uncomfortable though if in your pocket

Also remember, any app that uses hardware acceleration for graphics or video (games, browser, etc.) or gps will cause the phone to heat up if used for a prolonged period of time.

Are you sure I shouldn't worry? I mean, I don't want solder points falling off due to too high of a temp. Then again these temps don't even reach 100C yet. I've got the same app too probably, it's a battery monitor that tells u when the phone gets too hot. mine's goes off everytime i'm around 40+

Yep, I use GPS and often. It's just so much easier than guessing your way off a piece of paper. But yeah, like you the phone gets soo hottttttt. I have to always put the phone to my AC vent.

It's normal to a point.
These are serious computers we have.
Think of the old P486's back in the day, those things needed huge heat sinks and some even had fans
our phones which is what, 4x the cpu power and not only no heat sink but everything is squished together inbetween a hot screen and a hot battery
That being said, I use a program called A-see, which is to watch my security cameras while out.
And if I forget to close it out (Actually exit the program) It will keep running and running and eventually probably fry my phone
lets put it this way, I will actually start to feel it in my jeans pocket, it gets that hot.
Also I have a program which will alert me if my phone gets to 130 degrees F
And will automatically shut the phone down if it gets to 140
overheat protection or something

I had this issue where whenever I try to charge my phone it would overheat to the point unbearable to touch I went back to stock flash different roms in the end i exchanged it it was still under warranty

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.

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.
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!!

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.

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.....

If you're really that concerned just go exchange it.....

Yeahhh mines was over heating like crazy while I was transferring data from note 2 over too it
Sent from my SGH-T889 using xda app-developers app

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
