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)

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

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.

? 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.

[Q] Galaxy Note 2 overheating ??

Just thought I'd throw this out to see if anyone else has encountered this problem. Yesterday I was using some apps on my Note 2 (TomTom, voip, wifi and 4G ...) and I noticed the top of the phone getting rather hot, to the point that it was becoming uncomfortable to hold to my ear. This was much hotter than normal. I shut down all the running apps with app manager, but the phone stayed hot. CPU was running only about 10%. Finally I had to reboot...then it was back to normal. Its worrying that it could at some time be damaged by overheating. Has anybody had this problem and/or know what might be causing it? Thanks.

i got the same problem when playing a game in 10-15 mins it heated up pretty fast especially the front near samsung logo it was like over 100 degree

The only time I experience overheating is when I'm playing Need For Speed Most Wanted. It happens after about fifteen minutes of play. I haven't had it get uncomfortably hot but I always stop playing the game as it becomes abnormally hot. It's a shame to because I would like to play NFS more that fifteen minutes.

Yes that's the same area, near the phone speaker and logo, where mine was most hot. I'm thinking it could be cpu or graphics processor but I don't know the internal layout of components. But it seems odd on mine that it stayed hot after shutting down any running apps and only 10% CPU. Maybe something running in the background.

That is where the uber powerful quad core monster is grinding the gears of awesomeness at a mind blowing brain zapping 1.6 billion gigahertz lives at. And his girlfriend mali400 lives right next door and she is pumping out all the eye candy she can to satisfy the pleasure receptor s directly into your braiiiiiin.... Lol
In other words yes that's the main processor and graphics chip suckin up the battery. While it does that it's generating heat as a by product. It's completely normal. Nothing to worry about. Happy gaming. And it takes a while for it to cool back down to ambient.
Hope that helps

Did a quick net search on this and found a few forums reporting this problem. i.e. http://forums.androidcentral.com/sa...es-your-galaxy-note-ii-gt-n7100-overheat.html
I reported the overheating to Samsung Support. They said they have had no reports of the phone overheating...sounds unlikely after several months and millions of devices sold. Support suggests doing a data wipe from the recovery screen as this will "resolve most problems". Really? ???
Could be a firmware issue which Samsung will find and fix if they get sufficient number of reports. I suggest you report it to Samsung Support: http://www.samsung.com/us/support/...click on "live chat" for mobile phones.
Need for Speed is a game provided by (presumably) Samsung. If you can't play it for long, it seems like that represents some kind of inherent problem with the device. My concern is whether the overheating will be an ongoing, recurring problem. That would limit the usability of the device.
It's not clear if this is a problem that is worse on individual phones or if this is a problem common to all Note 2s. If its individual phones, then I'd probably like to return it for one that doesn't do this.
It seems the Exynos cpu is located near the speaker/logo. "System Tuner Pro" app reports system temperature under "CPU"

Mine is overheating while charging..I Woke up to a battery too hot message..the only thing different is I'm using a flip cover now,I took a screenshot of the temperature, and this was already cooled down a little..anybody know what this is? It's only been happening while charging though...

Samsung Note 2 Overheating Culprit
Two specific reasons : Quad core processor, Aluminium wiring.
Reports of deformity of the note 2 trickling in slowly. Try using processor hungry tasks and see it drop its jaw in 2 hrs.
they cant recall it, now its getting cheaper every day.

Try clearing the cache, supposedly things can occasionally get discombobulated. Last time my phone was about to set fire (gs3), cleared the cache & dalvik and it went back to normal.

I live in Chicago and summer days are already here. My Note 2 has started to let me down, since yesterday my phone is been up to 40c without any used.44 while charging. I dont think this is normal. Im on stock rom. Thank you in advanced.

Overheating persists
My 2 weeks old Galaxy Note 2 gets abnormally hot on the same area(rear camera part & the front phone calling speaker) while on charging, while playing games usually Modern Combat 4 or otherwise, & i am on stock rom as well. ...if anyone has a resolution for the problem then please share..

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.

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.

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.....

Serious over heating issue

So ive had my Tmobile G4 for about 3 weeks now. Ive been using the G series since it started. I love the G4 but wow ive never had a phone with this type of heating issue.
There is not a time when the phone js not at least warm to touch. Few times a day it gets to the point where its too hot to touch at all. Forget about making a phone call way to hot to lut against face.
Im not doing muxh of anything either. Web browse etc... But its hot at idle screen off just sitting there.
Anyone have issues with heating? Multiple times its given me the over heating message and shuts off phone.
Last night for example it got to 80c.... Thats fricken hot!
Could factory reset help it? I dont know what to do at this point? Am i just having to get a replacement? As i type this from my g4 sensors showing high 60 to low 70C.
The heat is generating from the top half of the phone btw. Like at the camera it feels like.
Any suggestions or help? Thanks

Is the battery draining abnormally fast? Check the usage for play service, could need that fix

If you live in a hot area like me, such as LA, then you probably experienced phone shutting down while using phone as a GPS due to the overheat.
I've never Had that problems with all of my previous phones but I'd give few software updates for optimization.

Yeah battery is draibing very fasy. I use a battery monitor and nothing is sucking it up.
Also, i live in Arizona where it has been 110 degrees daily. Though it hasnt shut down from heat outside or when using gps yet.
It shut down with over heat warning last night in my apartment where its 67 degrees in here while i was on google.com just browsing. So im clueless right now.
I just cleared cache partition and booted to safe mode to see if it runs any better.
I can leave my phone on my table for an hour and pick it up and itll still be scorching hot doing nothing. Its literally never not hot to touch.

My 1st Tmobile G4 Online Preorder had some problems mostly screen. I sent it back. I went to the store and bought one. That one was always hot as well. It was always throwing warnings at me. I had Gmaps on in my car with the AC on and only 70F out the time and it shut down on me. I called Tmobile and did some master reset etc and still was the same. I finally just went back to the store and told them to exchange it after they seen how hot it got in store. Tired to tell me I was at 15days when I went back in but I called in a few days before and asked what day was the 14th Monday or Tuesday I guess they count Purchase day as day 1 and that's what I thought but the person I talked to said no but they called Manager and they honored it. This phone finally seems to be good a few little issue's but they should get worked out soon with software we all hope. The 1st 2 phone's I had the Update Pushed to my phone the 3rd one was already on the phone so might be newer batch ? I was not happy spending over $600 on the phone with the issue's I had on those til this 3rd one which is good so far.

Then I'd say that even when it's doing nothing, it's still actually doing something, maybe just something it shouldn't be doing.
My Verizon G4 ran warm, and I was disappointed with the battery life. Different monitoring tools were unable to point me to what app (?) was causing the problem. Sometimes it would stay cooler after a reboot. Mine was never just constantly hot, however. Mine would be cool sometimes when sitting around, and then sometimes warm. Like taking it off the charger in the mornings, some days it would be cool, others it would be warm (~95F or so), when it had been just sitting there with the screen off.

Just now for example. After i replied here i out my phone on my table. I just now picked it up and it was 74 C. Scorching. Like its just gonna melt ibro a pile of G4 goo lol.
I guess ill call my store on Monday. Safe mode and clearing cache partition didnt help at all.

Are you using a case with it? I recently had overheating issues and figured out that the leather wallet case I was using was causing my G4 leather to overheat. It went as high as 112°5F But as soon as removed it it went back to normal.

Nah I have the black version normal backing not the leather version. I have the thin Tech21 case but i took it off a week ago to see if this helps.

Possible a Facorty reset could help? I really dont have many apps installed right now either. Since its relatively new ive been slowly installing apps. I started blank, didnt install anything from backups etc. The apps i do have installed are pretty basic. Nothing syncing or running. Ive been clear the recents aswell just to try. Frustrating

Have you tried turning off WiFi? I've noticed occasionally that my phone will constantly drop WiFi on my home router and reconnect a few seconds later, repeating this until I restart the router. All of that constant disconnecting and reconnecting makes it pretty hot...

Yeah its happening regardless. I turn data off when im on wifi and my wifi never loses connection, it stays constant. Though i did try a few days ago using no data or wifi and same dral, just hot.

Have you tried a factory reset? I leave my wifi on and stream music and everything. The only time it gets warm is when I Fast Charge. But I mostly wirelessly charge so its still cool.
Maybe you should exchange it.

I'm second on that doing factory reset. Seems like you have a corrupted profile or rogue app, or both.

I were having over heating problems on my G4. It were so hot at one point that my 6 year old daughter picked it up to play a game on it. The phone was that hot my daughter actually started crying cause the phone burnt her hand. This is not good. I have an awful lot of applications on my handset, over 300 so before I contacted LG I did a LG backup and reset. I restored probably half the apps what I had and a week after I haven't had a problem and the phone seems to be running as it should. The phone isn't even warm.
My theory is the G4 has 64bit processors. The snapdragon 810 processors were known for over heating and the G4 uses the snapdragon 808 processors for this reason. The 64bit processors deal with twice the data at the same time to the old 32bit processors and this contributes to them getting too hot. I feel that a few tweaks by developers and updates from LG is what's needed to combat the over heating. Time is our friend here and a bit of common sense. When you install a new app and overheating occurs then just remove the problem app. I always see how the app affects the handset now for over heating problems.
The 64bit processors in the G4 are new and need to have some updates to combat the overheating I feel. I recommend a system restore, debloating and only using the apps what you need.
I remember when pc's went from 32bit to 64bit processors. There were processors burning out, melting, water cooling became popular and bigger fans to combat the over heating. In time it sorted itself out so I feel this is the case for the G4 and other new handsets running 64bit processors.
Hope this helps.

Did anyone try unchecking the boxes in the my T-Mobile app? My phone went from 50% to %5 in less than 30 mins running crazy hot. You could also try uninstalling the app updates, or using the debloater tool on xda to disable it.

Same here, although not so hot that it "burns". iPhone 6 got warm but never so hot - software improvements should help combat this over time. +1 on the debloat tool.
One may argue the dead air via removable back cover can act as an insulator vs a compact design. Maybe just get an Otterbox/Thick case so you can't notice the heat as much? Could possibly lower battery lifespan though.

I've had my AT&T G4 for a little over a week. The first couple days the battery life was horrendous so I did a factory reset. The battery life improved greatly however that's when I noticed the top half of my screen getting unbearably hot. Another factory reset didn't solve the issue. So I talked with an AT&T Rep and am taking mine in for a replacement now. Hopefully will resolve this issue. Will update.
