Yes, most of them do go crazy when you operate them under extreme temperature ranges. The CPU generates heat, that is the optimal heat the phone can bear. But if you overclock it, or use under extreme heat conditions, its performance starts decreasing, as you might be probably aware that electrical conductivity depends upon temperature in metals. The colder it is, the better electricity it conducts, however a phone is also made up of semiconductors (about 75%), which increase conductivity under higher temperatures. that's probably the issue, since your phone's becoming unstable. You may even face the risk of loosing data if you continue doing this.
On a second note, why not keep icecubes all the tym with you...?

phones over heat using navigation

does anyone overheat from using navigation? anyone know how to stop this?
Are you oc? Do you have set cpu? Is your phone in direct sunlight on your dash? If you are oc'd get setcpu and usue profiles. Make sure you turn down your speed if the temp gets over 40c

i did that it still get hot, i turn it down to 346000 still getting hot
By hot, what temps are we talking? And what is your cpu clocked to?
40C i set the clock to 346XXX and still running hot
Yea I noticed driving over the weekend that the g2 definently overheats if navigation is left on for extended periods of time.

damn after a couple of google search this happen on other android device...theres gotta be a way to solve this, i bet its the polling frequency its trying to poll the thing to damn neear perfect real time therefore making it hotter, i think if we can figure out how to lower the polling interval it will help, but i hate programing so i dont know
Me neither. It's even worse on my Xperia x10.

Another question is if you have it charging while using navigation as that will definitely make the phone feel like it is overheating since the battery is getting warm from the charge.
mine always overheats lol
are you asking us or are you asking me? lol
Huh. Am I the only one who hasn't had this problem?
I run it on my dash, connected to USB power, constantly navigating and it never gets more than mildly warm. 246MHz-1.49GHz, interactive governor, CM6.1 RC2.
For the question about charging while navigating, yes that will def increase the heat coming from the phone. For guy who is "constantly" navi, are going long distances like over 20 miles at a time or navi short distances?

Mine overheats (uncomfortable holding) after using Pandora over the night. Still runs fine just hot as F!
i noticed that aswell when navigating with the phone. what can we say we got hot phones eh? yeah yeah lame i know. but i hope this dosn't damage the phone. Btw my phone isnt OC only rooted running CM 1.6 RC 3
The backplate on the G2 is also metal, so it might only feel hotter to your hand as opposed to many other phones which have a plastic backplate. This is actually good for heat dissipation (heat can escape vs. being trapped by the insulating plastic), bad for your hands.
well that brings to me the question when is it consider dangerously hot?? 43C is the max i seen using navi
bump for anyone with a fix
This is nothing new. My N1 got really hot when plugged into the car dock and navigating.
It never caught on fire, and had no permanent damage. The worst part about it was the charger couldn't keep up with the phone. I would get to my destination, take the phone out of the dock, and it dies right away because the battery is dead. I haven't used the G2 for navigation on a long trip yet.

Overheating and touchscreen non responsive

Today i was using Google navigation while driving and recharging. After approximately one hour i took the phone out of the holder and it was very hot and the touchscreen was not responding.. took out the battery and left it to cool for an hour.. then it worked find again..
Has anyone had this problem or know why it happened? Could this cause permanent damage?
I'm running cm7 rc1 with the radio from 27jan.
Thanks in advance!

Charging the battery creates heat.
Lengthy GPS usage creates heat.
Heavy 3g/4g usage creates heat.
Holders and cases trap heat.
When a smartphone overheats it locks up or shuts off.
This isn't really an android or device specific issue as most smart phones do this. Some phones have countermeasures in place such as metal that extends from the high heat chips to the outside of the phone to help dissipate the heat and some manufacturers assume you wont be doing this combination for whatever reason.
If you let it overheat often it will eventually cause damage to the circuitry. Some different roms MAY help marginally but it is not really a rom specific issue either. If your phones had better heat dissipation it would cost more. It is one of those price balance issues in the manufacturing/design process.
Some things to try
Take it out of the case
Put a fan or vent(in car) on it
Don't charge at the same time your doing gps functions
Thanks a lot for your reply...
Do you by any chance know an app or something to monitor this temperature build up?

Galaxy S II very hot

Hi.Is it just my S2 get hot when I play games or use GPS? Especially at the top around the camera.

Normal.
Yep, very normal. However I did find that using GPS really heated things up... next hottest is games

I had similar issue this morning. Listened to music then watched a video (20 minutes) on morning commute and device got very warm, felt it in my pocket. it soon cooled down but still a bit conerning....

probably using that particular GPS software, not just GPS antenna by itself?
does it heat up if you just display GMaps with your location, without doing anything heavy in GMaps? Because I did not notice that much heat coming from using light GPS apps. Gaming - yes, some of those games are killers.
I am using Navigon software. I played Angry Birth and the same,phone was hot after 5min. I know is normal that phone is warm, but this is not warm,but hot.Galaxy S was cold compare to S II.

Of course it's NOT normal. Might be normal for SGS2 but not for others. as I've said on another thread, Navigating with GPS driving it got to 60C, you could slowly cook an egg at 60C.
Mine doesn't get especially warm, It gets well 4-5 degrees warmer when I browse the web or watch HD movies
It's think it's high screen brightness in combination with SW (high CPU load)!
Mine is never warm if brightness is kept below 50%
My screen brightnes is 0%. It is hot at the top where is CPU I gues.

How many degrees celsius is taken as very hot on the Galaxy S II?.
I was overclocking my Galaxy S II earlier and my temprature was up to 46 degrees celsius when i was running a stress test on the phone.
So i just stopped my stress test of the phone then.
How did you measure temperature?I have just battery temp. it is 42.

You can download the same stress test program as i'm using from Android Market. It's called StabilityTest v1.5.
it will test your CPU's on your Galaxy S II if you are overclocking it. But you can check the temprature even if you aren't overclocking.
the temp rise is sort of random, i can play games for hours (and its 26C here) with brightness on auto and so on, it doesnt get hot
then suddenly, it does, sometimes even when im not doing much
didnt get the time to pin point w/e thing creates that behavior
(and when i say hot ofc im talking of very very hot - which is what everyone talks about imo)
killall or restart and its good to go til it happens again

I'm running that app now. I wanted to get an idea of temperatures at stock before undervolting/clocking so I could see how much difference it made. But the phone is seriously hot to the touch, enough to be worrying about. The app's reporting 50C after 37min but it feels hotter than that to me.
Some components are designed to run hot. For example I have an ATI 4850 that happily runs 70+C at idle is rated for up to 120C. But I'm worried even if the exynos can handle these temps what about the other components? The top of the screen feels even hotter back. Could this cause damage to the display for example?
This is my first smart phone but having that much heat in such a tightly packed device seems like a recipe for failure.
You will find temps of 50 deg centigrade and more when using all resources of SGS II (e.g. nav with wikitude drive = camera on) and phone attached to car screen on a sunny hot day.
This is normal!
Touch a nav-device in action and You will find it glowing ......
But contrary to HTC HD 2 SGS II does not freeze or crash at that point.
Leave a device switched off in direct sunlight in a car and it will get hot too, but still it will work .....

my phone was getting extremely hot when benchmarking etc, this was default clock and voltages.
the phone reported it was reaching 50 degrees. thought this was "normal". this was on the firmware the phone was running outta the box.
flashed latest firmware and have since messed about with overclocking, @ 1650 my phone never got as hot as it did stock.
so if you have not done it, flash the latest FW...
So your cpu is not 1200 but 1650mHz now?

Been running tons of different ROMs on tons of different Android devices, and every once in a while there is a particular combo that gets tremendously hot.
Once had my N1 get so hot while using Co-Pilot Live and Spotify while plugged into a car charger, that it turned off and wouldn't come on again for some 5-10 minutes.. Definitely worrying.. Switched ROMs and never saw the problem again.

N4 getting pretty warm for anyone?

I'm coming over from a thicker EVO 4G so maybe I'm just not used to it in thinner device, but when i watch a video, or do something with motion in it like a camera, the top of the device gets a good bit warmer then the rest of it, at about the level of the volume keys. It's not instant, but it takes a minute or two to happen.
Has anyone experienced this? / Do ya think it's normal for a thinner device?
I've noticed it on Stock as well as a custom ROM.
Known issue. There's other threads about it. Glass conducts heat more than plastic, among other things. Check out the other thread, probably in general.

Not after undervolting
having own a Gnex and now a N4, this thing barely gets warm... the Gnex was VERY HOT, to the point sometimes at lunch i had to turn the AC, put it on MAX, set the phone against it without the battery cover for about 2-3 minutes, to cool it off..
the N4 has never got hot on me
OP, check if you have a "Slow" binned CPU. Those have higher stock voltages and therefore get hotter faster

Fast.
I'm trying to understand, is a good thing or a bad thing?
I have 'nominal' and yet to encounter phone warming up. I can also UV using faux clock if I ever need it

Does This Phone Get Hot?

I've read lots of comment about the N4 getting hot under normal use. Is this still the case or has the issue been addressed. I'm seriously considering buying this phone but I don't want a phone that gets hot.

Mine hasn't gotten to hot.
Those reporting this problem are probably a minority of all nexus 4 owners.

Yes the phone does get hot sometimes especially after 10-15 mins of continuously browsing the web on 3G+ or 3G and after 15-20 mins on wifi.. But that's for stock 4.2.2 and 4.3. After undervolting and underclocking the device using custom kernels and ROMs the phone does not get very hot.. It's between 37-40 even after playing games like nova 3 and nfs mw for an hour if you hold the phone with your bare hands and it obviously depends on your configuration.

Thin glassy phone + powerfull cpu = heat Nothing to worry about.
It gets hot, at least on stock firmware, although my definition of hot might be more sensitive than others. I don't know what it would be like talking on the phone for an hour with it getting hot next to your face, although I haven't done that. I have to use custom rom and underclock the cpu a bit, so it's not an really issue anymore. I probably will get flamed for this, but I don't recommend this device to you if you don't like phones getting hot. But I guess lots of these newer flagship phones that has thin plastic casing probably gets hot too.
With normal usage the phone doesn't get too hot or anything. If you are fond of overclocking and disabling thermal throttle you will get pretty high temperature's. Around 70 degrees celcius.
It get's hot as any other phone but because it has got a glass back you feel the heat better.

It didn't feel warm at all after undervolting and limiting heat using Trickster Mod (and has been yundervolted for the past 3 months).
Before that it could sometimes get really hot though.
Yes very hot, don't buy it.

Yes it gets very hot but the thing is you can still use it without getting very hot if you play games then yes it will get hot.

Is your phone undervolted and temprature limited?
My temprature never goes over 40 degrees celsius, and feels rather cold most of the time.
Even with rather intensive games like NFS Most Wanted
This phone will not burn you. There isn't a real reason to consider the heat a problem. The temperature of the phone is regulated by the kernel, if it gets too hot the kernel takes measures to reduce the amount of heat being produced. This is a non issue.
