Its been getting cold and I have the vent mount for my GNex. Just wondering if the constant heat coming from the vent will damage the phone??
any ideas? i've heard/read that a/c will not cause any problems because it actually cools the phone down but the heat is opposite??
Heat is bad.
Yeah heat is bad, and can damage your electronics depending on how hot they get. In addition, battery life suffers in heat as well.
Please allow me to revive this thread. I have a similar problem.
A friend drives a Mercedes A, where the central dashboard vents emit hot air when the heating is on. She also has a Galaxy Nexus.
Unfortunately, the relatively small car has no other good place to attach the phone holder, so I am trying to think through all the consequences when putting the phone holder to the central air vent.
I rule out a suction cup holder, because it has too many severe problems, in my experience, like being in front of a bright background, blocking part of the view, not sticking well in freezing temperatures, being too far away from the eyes, etc.
So what are my options? I have to re-check the car to find out whether it is feasible to close the central vent or close only the lower part of it that would blow towards the phone. But that would reduce the heating performance and is therefore less than optimal.
Another question is, which temperatures are we actually talking about? The phone certainly withstands quite a bit of heat and even heats itself up when constantly working, like when navigating. If the air from the vent is not as warm as the phone, it would even be cooling the phone. Since the car is not a sauna, the air from the vent may only have to be something around 30°C (86°F) and, I hope, less than 40°C (104°F). These are not phone-killing temperatures, as they are normal in hot places. I am sure that the Galaxy Nexus would not cease to operate at 40°C, because otherwise it could not be used in tropical countries. I regularly use mine in Africa in thin air and at high temperatures and have never had any failure so far.
But I would be very interested in any actual experience with a smartphone in front of a heating air vent in a car. Please report here, if that is what you have.

I don't know if I am being paranoid, but I feel the slightest tingle/itch in my hand when holding the GNEX (gsm), this is not when the phone is charging just during normal use. Took it back to shop the guys there thought I was crazy
Anyone notice anything similar?
It might be the 3 pogo pins on the side of the phone. Try putting sticky tape over them and see if it changes anything. Some people are just more susceptible to getting shocked than others.

Certainly can't rule out entirely the possibility that you're feeling something, but the chance is extremely remote.
The battery is a standard LiIon single cell @ 3.7V. When operating, it's probably around 3.5-3.6. That is well below the sensitivity threshold for virtually everyone on skin.
Further, if you were this sensitive, you would have encountered other low voltages that tingled your fingers/hand over and over, so you likely would know what this was already. Heck, if 3.5 volts gives you a tingle, handling a 9V battery would be rather uncomfortable!
It's likely psychosomatic, or maybe some peripheral nerve reaction to the pressure from holding the edge of the phone -- not uncommon when pressure is applied to a narrow ridgeline in the palm or fingers.
Thanks guys. I think I probably am a bit extra sensitive to dc current. I'm just worried that I might have a defective unit. I've been to few shops and the demo units are housed into anti-theft devices so u can't actually hold the phone.
ok, I found that when input the phone in airplane mode I don't feel the tingle. it's got to be a faulty unit. I am going on Holliday in a few hours for a week, will take back to the shop when I return and get them to exchange it.
Will pushing my phone to its limits via playing 3D intensive cause the phone to slow down. I notice it gets rather hot and it leaves me to wonder if its causing wear and tear faster than just normal usage. I intend to keep this phone for another year and ahalf and would like it to maintain its snappiness. I understand theres no moving parts but that heat cant be beneficial to the hardware.
While prolonged overheating can be bad for things in there, if it happens in short terms, I wouldn't worry TOO much. Perhaos find an app that will let you know internal temperatures, and if you think it's getting too hot, shut it down for a while. In other threads I've read, clearing the dalvik-cache seems to temporarily help as well, if you're rooted.
My phone generally heats up while on a long cjarge with its case on (I remove the case to let it breathe now), during long periods of playing graphic-intensive games or running programs that use a lot of my processor (I underclock things at times now, helps a bit), and in the car when using GPS (I'm in Texas, though...gonna happen.)
None of these things have gotten the phone as hot as I had to when I replaced the glass lens. Lacking a heat gun, I used my hair dryer on full blast to melt the adhesive. By the way...leave it to professionals. It worked out, but shattered glass stabbed me a few times. But during the process, I had to get it so hot it hurt a little to touch. Of course, the focal point if the heat was the glass, but I digress. I'm running the Jedi Master ROM, and the only tines the phone lags is when I start typing to fast for it to keep up. System, ui, all that still works pretty well. Well, except when I break it.
As long as it's not TOO hot, heat is going to happen. This is a fairly power-heavy device, so when it gets going, heat is a by-product. Just keeo a weather eye out and judge it by your situations. Youbshould be alrigyt.
is anyone noticing that there s6 is overheating mine is i am thinking of bringing it
to the sprint store

The phone does get very warm.
This has been noted in other variants.
It's a processor thing.
You should be good.
And if it gets a bit nippy you can run antutu and heat your hands.
It's not a bug it's a feature.
In all seriousness. My s4 and s5 did the same thing my s5 got so hot sometimes i was tempted to try and fry things on it.
I wouldn't worry to much it's likely nothing.
For the sake of science I decided to heat my phone up with antutu
and test with my Laser thermometer (which is semi accurate to about 4 degrees)
With my phone face down and not being touched i recorded a peak temp of
96.7 degrees F
while holding it (and thus not allowing heat to escape as easily) i was able to get it as high as 98.8
this would be similar to what you will feel in a case.
I conducted the test in a 64.3 degree room
Them temperature of my fingers/hands ranges from 63 degrees to 82 degrees (remember external not internal)
so there is AT LEAST 14 degrees in between the hottest part of my hand and the phone.
which is noticeably warm. and at most 35 degrees which is often the difference between a blistering summer day and an air conditioned office.
This is my 6th samsung and I don't think i have had one yet that made me think "Dang this thing sure doesn't get warm"
TL;DR
Yer phone is just fine. If your'e concerned find a way to measure the temp and compare them to what i've posted.
And if you can't shake the feeling you can take it back to sprint.
Although I can't imagine they will actually be useful.
Or that you would want to actually be in the sprint store.
yeah i agree i should be fine i have been reading around and almost everybody. is noticing
the same thing also if i put a case on that should help to.

Actually adding a case will just make your device warmer.
however it will be less apparent depending on the material of your case.
either way out of sight out of mind right?
Thermal Imaging
Just a quick note about thermal imaging (as I do it all the time at work...). Be sure you catch the shiny surface of the phone at an oblique angle so it's not flashing light into the phone. That will skew your temperature reading high.
I will be traveling from California to New York starting this Saturday. I bought a universal dash mount so I can use my M8 for GPS. What I was wondering, how can I protect my phone from the sun or heat damage? Will having it in a case help it at all? Or will I be ok like it is?
Regards
As far as heat, I wouldn't worry about it too much. As long as the interior of your car is a decently comfortable temperature (running vents or AC, or windows open), your phone should not overheat. I'm just guessing that you don't like to make yourself excessively hot while driving? Anything remotely around room temp will probably be fine. And if you happen to have a phone mount that puts your phone near any AC vents, you will get some extra cooling that way.
I wouldn't recommend leaving the device in a hot car; and you probably wouldn't for security reasons anyway.
In terms of sunlight: in a broad sense, sunlight will breakdown most things over time. Although your car windows block out most UV (windshields more so than side and rear windows, from what I'm reading), which is probably the most harmful factor. Not sure what route you are taking and how long the trip will last. But I'm guessing a few weeks at most. And that degree of sunlight through car windows will probably not have a huge effect, I'm guessing. Plus, the exterior of the phone is mostly aluminum and glass, which aren't terribly UV reactive. The plastic antenna trips are probably the most vulnerable. A case (especially an opaque one) would certainly reduce any damage from sunlight. But may also make the phone a bit warmer (hold heat in).
Another thought, is that using the phone for navigation is very battery intensive. Not sure what app you intend to use. But at least when I use Google Maps (which uses both the GPS function and network data) most car chargers can barely keep up with battery drain. Meaning I hardly get any charging when using navigation. I'd suggest getting a QuickCharge 2.0 car charger (if you don't have one already) as it will charge your phone even when running navigation. Well worth the $15-20 for a QC2.0 charger, to be able to charge your phone quickly since you'll be spending a lot of time in your car; let alone using navigation intensively.

Thanks for all the info, will help for sure. I'll take a pic to show where my phone will be mounted. It gets hit with direct sunlight, and the A/C vents are below the phone that was my concern. I didn't think about the quick charger, I'll pick one of those up for sure. Here is the pic I was talking about. http://i76.photobucket.com/albums/j17/DemonExecutor1/20150527_072736_zpsvlbkm8wz.jpg

Sunlight, but through the windshield, which filters both UVA and UVB (probably even says this on the glass). Yes, you will also get a bit of light through the side windows; which are usually just UVA protected (not UVB), and the phone may even get some direct sunlight from the side windows rolled down. But I'd say this isn't any worse than most folks setup. True, its a little more direct light than my setup, since you have it on top of the dashboard, where mine is in front of it. But mine is still in sunlight much of the time.
Also, it seems you can point one of the vents up toward the phone, and get some extra cooling that way. It won't be directly blasting the phone, but should still send some cool air in the direction of the phone. Not really a "requirement" but not a bad idea, either.

Thanks for the reply I'll try to point the vent towards the phone.
Have had reboot issues for a while now and they were just getting worse. Nubia said to send in for out of warranty support, but thankfully that process is severely broken as all of the repair contacts they forwarded were either out of service or foreign language (Czechoslovakian!?).
In any case, I figured the phone was done so decided to take it apart and lo and behold, it seemed to last a bit longer between reboots when the back was off. Assuming it was a heat issue, I tried replacing the thermal paste where I could with varying results, but ultimately I ended up taking it completely apart to access the face of the SD 888+ chip and replaced the blob of pink goo covered with copper tape with a 1.5mm copper shim along with MX-4 paste. 1.5mm seemed to be the right spacing and the 15mm by 15mm shim I had only needed a few edges reshaped to fit within the housing.
So yesterday I put it all back together and no hint of issues yet. Longest time it's run without a reboot for at least a month.
I suspect I may have accelerated the breakdown of the cooling since I often put my phone into a bicycle mount which I think puts some pressure on the back of the phone, likely squashing the paste a little flatter each time till it was no longer making contact.
Anyway, if you do start seeing random reboots, this might be the issue.
Though it feels like I'm talking to myself on this forum. Are XDA forums not what they used to be or are Redmagic phones just not as popular as my Google feed is leading me to believe?
If you're using it in direct sunlight you aren't doing it any favors. You can fry a phone like that rather quickly. The thermal shutdown may not react fast enough to prevent hardware damage...
Limit SOT in direct sunlight to seconds not minutes especially in high ambient temperatures.
Monitor battery and CPU core temps.
If the phone feels hot, it is hot!
