Heat on the top right of the phone

I was playing games on my phone for an hour or two and noticed in the top right of the screen about where the power button is, it was getting really hot. Just on the screen face. I took my cover off and felt around the back and it was cool. But it was getting noticeably hot when touching that part on the screen. Has anyone else noticed this?

Yeah..must be where the CPU/gpu is

I'm worried about Heat for my phone E4GT too.
Idle, it's around 27c, which isn't bad at all.
But during usage it jumps to 34-37c, and wireless tethering causes it to go 49c.
My GTX 570 runs idle at 37c, that's fairly cool for a GPU but my knowledge in phone hardware isn't nearly as great.
What kind of temps can this phone handle?

Same issue here I m so pissed

The highest mines gotten so far was 116F but it was charging with my HTC charger and i was playing a game. The odd thing was the main part that was really hot to the touch was the top of the screen near the ear piece and it wasn't just warm it was hot. But that's only happened about 2 times now.

Third phone and still experiencing heat issue
I have changed my phone twice at Sprint and, for each one of them I have experienced the heat issue. Sometimes, the temperature goes as high as 53 degrees. I am not sure what exact combination causes this problem. I have seen it with or without 4G on - charging it makes it worse. Rebooting seems to help.
Makes me worry about this phone. I really like this phone but I definitely don't want to deal with a heat issue.

Heh, just try using this phone with zedomax's kernel set at 1.5ghz and playing Dungeon. Hunter HD II for an hour . . . it gets blazing hot! No performance issues through, only immense heat

Phone runs hot when playing games?

Anyone have this condition?
It gets warm with heavy internet usage. But quite hot when playing games.
I was playing 'great little war game' for around 10 minutes then I felt on upper right corner (behind front camera) quite hot. I checked the battery temp it was 43°C. But as soon as I quit playing the temp back to normal.
Just asking if anyone experience the same, is it normal?

Don't quote me as I am not an authority on the subject but usually when a certain spot on a phone starts to heat up, it's easy to assume that the CPU is starting to get hot.
Games are CPU intensive tasks so you will see a specific spot where the CPU is likely to be located getting hot. There isn't much to remedy it since phones don't have a cooling system built in.
My only suggestion would be to try and hold it as such so that you are not directly touching the spot and try taking breaks when you get worried about the phone getting TOO hot.

Most phones will run hot when playing games

I forget what game it was but my iPad 2 was cooking when my wife was playing a game on it recently. It's just the way it goes.

Phone becomes slow when hot?

Whenever I play 3D games on my phone, it gets really hot which I think is normal, but the phone also gets really laggy. So laggy that it's almost unplayable. Then I wait for 5 mins for the phone to cool down and go back to the game again and the runs smoothly until the phone gets hot again. Is there anything wrong with my phone or is this normal? I'm on stock 4.0.4 rooted and the game I was playing was Drift Mania Championship 2.

Its called thermal throttling. The CPU throttles down the clock speed when it gets too hot to avoid damage to the chip. I think the heat being developed by this phone is outrageous. Biggest flaw of the device. There is nothing you can do to keep it from getting hot when playing your game. Mine gets up to 90-95 farenheit when simply watching YouTube. Its really bad.

Yeah, it gets a little warm using chrome too , but it's a nice hands warmer during the winter.

Lol.. its honestly sad.. i cant believe they would make something like that. But you could use Ktoonsez kernel and lock the frequencies, however you most likely would damage/shorten the life of the CPU.

[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..

The heat Issue?

I am thinking to buy the phone but I saw some posts there are some heat issues. So what is the problem besides the phone getting too hot? Is it shuting down when it gets too hot or get really laggy? Is there any other problem when heated except it gets really hot?

I haven't experienced any heat issues. I have yet to feel my g3 get warm Tbh.
Others (not sure which model) have reported issues with heat, to the point that it causes the device to throttle the brightness down. Again haven't experienced this on my at&t model.

Thanks for the reply, someone with issues ?

Same here not felt it get warm even watching video.

When the phone gets hot several things happen.
1) The CPU is clocked down to help lower heat
2) Brightness is capped to help lower heat
3) If the phone continues to get too hot (usually when its already hot and you then start to play a really intense game, or benchmark the phone may shut itself down.

People complained a lot with the Korean model but I haven't seen anyone with a US model complain. Maybe the type of person that waits is less likely to be a phone gamer? They may have actually tweaked it so it doesn't activate as quickly or harshly. I do know some people disabled it on the Korean model. I haven't heard of anything bad happening but those few people may have felt dumb if it destroyed their phone and not posted that it did...

I have no heating problem with my lg g3 international D855 16gb model, even during quadrant test or playing games.

Define an actual temperature for hot.

I disabled the thermal protection on my AT&T version and yes, I've felt it get quite hot while playing Final Fantasy 6. The heat radiated mainly through the metal power button but the entire top half of the device got pretty hot. Didn't bother me all that much tho, as I've had other devices get hot like that in the past.

I use exposed app CPU temp my g3 sits at about 30c and 45c which is normal temps and about 50ish whith thermal protection on disabled.

what heat issue

Do we have any official documentation from Qualcomm on how hot the cpu can safely be?

My girlfriend picked this up yesterday and this is happening to her G3. Not playing games though, just browsing the internet/reading an article. It makes no sense to me. How can you take control over that? She doesn't want to root the phone.
But yeah, just reading something or even looking at Facebook, the phone gets way too hot.

I picked up the Verizon version yesterday. It's gotten pretty warm around the power button a few times for me also. Typically not bad or what I would consider unusual with one or two exceptions.

My G3 (UK) go very very hot yesterday when I was on the train playing a graphically intensive game.
It shut itself down and then refused to turn on again. Ever.
I tried everything all night but no joy. I got a replacement handset today.
I'm sure it was because of the overheating that the phone malfunctioned. Without knowing exactly what has happened to it the timing is too coincidental for it to be random hardware failure. It was SUPER hot!

This is strange. Does the kernel not shut the phone down before it "fries" the SOC?,unless the throttling temps are too high? Wonder if this is linked to the display flickering problem myself and another poster had.

Funny you mention display flickering. I had that about 2 weeks ago. The display started flickering really badly, like nothing I've ever seen on any Android device, and I needed to pull the battery to reset. It didn't boot straight away either, it had to cool down a bit.

this.
all phones get warm if you are on it for an extended period of time, surfing (using data), gaming etc etc screen on for long periods of time. those saying they can game and not have heat are lying to you. phone gets warm when screen is on for extended period of time and by phone I mean any phone

Yeah, i had a flickering display which didnt go away.I returned that phone. Another poster yesterday had the same issue.Im wondering if the GPU is frying itself? Although the GPU does throttle as well as the CPU. Running Antutu I would get 60+deg C maybe playing a game for an extended period of time for example is causing damage? Just a theory.
