Hey guys, I have read many reviews where people complain about overheating and excessive amount of heat from the phone localized in one area. Based on the tear down provided by ifixit, there looks to be no EMI shield over the CPU/memory chip area unless it was removed before the photo was taken. But either way, I see that when assembled there is the metal backing to the LCD directly above it which would really dissipate the heat well.
Why not purchase some thin thermal pads and apply as necessary to transfer the heat to the metal frame directly above it. Even if there is an EMI shield over it, open it up (unless it's soldered making it harder) and put the thin thermal pad in there and on the outside of the shield.
Seems like a very simple solution to fix a pretty big problem. I don't have my hands on a Nexus 4 and am unsure if I will in the future but if I ever do I will definitely try this and provide results and instructions on how to do the same.
Or LG could design the phone better.

Is not a bad idea actually, but i'm not too sure if the display will soffer about it
If only had a n4 to test it XD (i have some thermal pad lying around)

While I agree with you, thermal pads are relatively cheap and the concerns about pressure on the LCD by another poster would be fine as long as you use a thinner thermal pad that doesn't compress too much after application. I have various thickness of thermal pads so as long as you use the correct one to apply just the right amount of pressure I can only see a large benefit from something so simple.
It would require opening the device and I am unsure if there are warranty voiding stickers in the phone. Some people are really happy with the phone and this is the only problem so I am merely just trying to provide a solution to the one problem remaining.
Thermal pads are to conduct heat from one surface (CPU) to another (heatsink). I can't say I agree with using the screen as a heatsink.

I wasn't talking of the pressure but the heat that the backplade dissipate, maybe can damage the screen
I doubt it will help,
someone pointed out that the only trigger for thermal throttling is the battery temperature,

Yeah, i would guess the space there is to keep the heat from the screen...
If this phone runs hot it is most likely due to the glass acting as an insulator. Is there any venting anywhere? I bet much of the thermal issue could be solved with a well placed vent..

While I can see concerns about damaging the LCD due to the heat but I imagine heat spread over the entire surface of the phone is much better than localizing a much more intense heat in a smaller area. LCDs can withstand a decent amount of heat and a small arm chip spreading heat over the entire surface of the phone would be very minimal to no effect on the LCD. I can see great potential for damage allowing the heat to be confined to a small area (just the CPU and RAM sitting on each other) with no heat spreader or heat sink.
Well I guess we won't be overclocking this phone anytime time soon. And you know I was really hoping I could finally fry me some bacon strips on my way to work.

Air is a very good thermal isolator, i read that many desktop ips lcs have a maximum teamp. of 35/40 C° so if if the cpu heats a lot it can create problems. I don't know how much is the max temp that this ips can withstand tough.

I really think this whole heat thing is a kernel issue at the moment. I remember owning the one x since very 1.26 or was it an earlier one? Either way, the phone would really get VERY hot. After a few updates i barely felt the heat. Maybe when playing games or whatever, all in all the updates solved the issue. I think google will manage to sort it out, i can't imagine them being that stupid.
I guess if you are concerned with the LCD becoming damaged then you could just put the thermal pad on the other side to make the whole motherboard (minus spring contacts) contact the glass back and spread the heat outside including the battery.
And yes air is a very good thermal insulator so all the heat is just getting trapped inside the phone. Gotta use some thermal pads to conduct that heat to a panel exposed to the outside.
These are all just suggestions that I would do if I were to have one in my hands right now.

The bottom line is if the SOC or N4 design is flawed internally which created thermal throttling, then there won't be much help for inserting thermal pads. I have tried this with HD2 when it had thermal runaway. There was a huge thread figuring out how to cure it by many methods as far as putting the motherboard in the oven to melt the soldering at exact time and temperature. The thermal pads method only decreased a few Fahrenheit which wasn't enough to cure if there was a thermal problems. My HD2's SOC was made by Qualcomm. Something definitely don't add up with bad benchmarks scores, thermal problems. Could future updates cure this? Only time can tell.
I've done something similar with my OCed Samsung i9000, but instead of using thermal pads, I used thermal paste. Similar to the Nexus 4 the cpu IC is sandwiched between the PCB and the metal chassis. The metal chassis becomes a massive heatsink for the CPU which dropped my CPU temp. by 10oC (~17oF) at maximum load.
After 9 months of use there hasn't been any damage or deterioration of the display screen (AMOLED).
Details can be found in the i9000 forum.

When I receive my Nexus 4 I plan to do something similar.
The only problem i can see with this method is warranty. I'm 100% sure that even if there is no warranty void stickers on the screws they won't accept to fix a phone that has been tinkered with
And try to wipe thermal paste without leaving any trace you will fail

It is not flawed as such, it is just overdimensioned.
In essence it is a double APQ8060A + quicker (more power hungry) GPU + additional management circuitry. So it should not surprise, that under full load (benchmarks) it burns through more than double of the usual dual core Krait phone power. While having similar dimensions/power dissipation capacity.
In their marketing Qualcomm positioned this SoC for Tablets. Now you have it in the phone. Is it bad? Not really, full power quadcore tasks is not a realistic task for a phone. And for a second or two (after this it does not matter anymore since your phone "lags") the existing cooling is perfectly adequate.
One thing where Qualcomm/LG/Google could do better are the GPU drivers. Which currently seem badly tuned.
To all people who have this problem! I recently got the Nexus 7 3G and the back was creaking so badly you could easily hear it across a large room. The noise seemed to come from the "nexus" logo near the top of the device.
I found the culprit an double checked with an older 16GB model. They changed the design of golden contact springs for the wireless radios from a simple C shape design to some complicated folding Z shaped spring design. It is those springs that upon being depressed rub metal on metal and make this horrible creaking noise. I don't know how many 3G's are affected but mine definitely was.
My solution was to open it up, which is easy enough to do with a guitar pick or something similar, just check YouTube, and to bend the springs until they stopped making noises under load.
While I was in there I also added double sided tape wherever necessary to stop the plastic from creaking (because they left out a lot of the foam they put in the older models, maybe to fix the screen lift issue??) and I re-wrapped the battery protection circuit because the circuit board was rubbing on the battery and making noises as well. (also, my battery was strangely wedged sideways in it's compartment)
All in all it's rock solid now, no creaks, nothing. And it feels like a really quality device now. Suffice to say that I should never have had to do this in the first place in order to own a device that is in satisfactory condition and one is not embarrassed to pass along in a group of friends because of the noises it makes

Bookmarking so I recognize your nick on an upcoming "My wifi doesn't work!" thread.
Don't worry about your warranty! there is a "seal" sticker INSIDE the case but popping the back off will most certainly not void your warranty. it's more like the battery cover on a galaxy s3 or a nexus s than anything else!

Lg g4 thermal paste mod
This is my guide for applying thermal paste or pads to various parts of g4 to help disapate heat better.
i personally use Arctic silver About 12 dollars american at any radioshack.
1st of all I am not holding a gun to your head, Im not forcing anyone against there will if you are not comfortable tearing down your phone,
dont!!!!!!
In recent events of loads of g4s bootlooping.
I want to say i have a 10/15 g4 hardware rev 1.1 have had it nearly a year and so far no loop.
Prob wishful thinking but I want to say this may be why helps get rid of the heat off the old girl.
3 screens later, 2 camera lenes, and a leather back. still rooted on zv6 So up yours LG.
So lets get started
1st remove back cover and in my case i have a cell phone repair kit with the screw drivers and prys. Remove all the screws in the frame assambly. There are 11 of them.
2nd carefully pry the rear frame apart from the screen assambly.there are no wires to disconect yet. Do not force her apart she will come apart when all the clips are released.
3rd once the backplate is free there are 3 wire clips 1 on the camera one next to it for the light sensors and down near the bottom rite under the battery.
4th you can leave the camera module in just move the three wires slightly to the side and carefully remove the board flip it over and again carefully pry the big tin away from the board.
5th im a little eccentric so i applied the paste to all 5 chips underneith the tin just a very small dab goes a long way see in pics attached
6th when putting the tin back on make sure its lined up on all points.
this is also a common ground connector on most phones.
From here just reassmble and enjoy!!!!
Whole procsess took about 20 min
Before I started I was at 45 Celsius now after moderate usage to check temp 29 celsius.
Ive run the piss out of this phone. sold it twice and got it back wireless charge.
Shes a soldier.

Can you clarify - did you put the thermal past *only* between those chips in your picture, and the little metal cover that goes over them? I can't tell if you also put it between the metal covers and the frame of the phone?
Yea i did a small smudge on each then i put the cover back on arctic silver is a pretty nonconductive paste i try not to put it on everything all sloppy but ive never had it liqufy and run any where either some people say it does i didnt put none on the frame or cover.
Im not familiar with this layoit either knowin my dumb arse i put it on the wrong chips but i went through my g3 and actually done a bunch of them in small doses of coarse throught the whole board
Kingfattys diagram is rite i couldnt find a diaram of the board so im partially wrong. I will update tonight ill do another tear down and take more pics
The proscessor is on the backside. Thats why i ask for help to im goin off a old setup.
Ofcoarse it never hurts to coat more chips all produce heat. Ill label the diagrams and do a complete guide rework tonight on my computer
figured id brink this back up on the thread list
so
Bump
dont know if its helped guys.
but so everyone knows i havnt had a bootloop issue on my g4 yet to date again knock on lgs synthetic leather.
there has been a lot of discussions of heat being the primary cause for the failed solder joints and maybe this helped maybe it didnt

Yeah, I'm not one for benchmarks either, but it can give an idea of the health of the hardware. I did notice lower scores on some G4's I think it may be because of throttling due to overheating though. I get around 70,000, if I put a little pc fan next to it, it gets 71,500.

Nice video. Summary of procedure:
1) open the phone to reveal the circuit board
2) remove the large metal shroud or plate covering the processor chip and memory chips
3) cut out and remove a section of the large metal shroud that would normally cover the processor chip
3) get a piece of "heatsink tape" (e.g., thermal tape, he uses a tape with copper on top and adhesive on the bottom) and cut it to fit on the top of the memory chip, apply it to the memory chip
4) replace the large metal shroud over the chip - this covers and sandwiches the thermal tape on the memory chip under the shroud, while exposing the processor chip due to the hole you cut in step 3) above
5) apply another section of large thermal tape over the exposed processor to extend beyond the processor to the sides, covering over the metal shroud too (*this I disagree with, see below*)
6) apply a small section of thermal tape over the metal shroud located where the memory chip is located
Disagreement issue: there is a gap/divot over the processor, which will no longer make stiff contact with the frame when you assemble the phone. You can see the divot around 13:00 of the video, how the thermal tape "dips" in over the processor.
To fix, I'd add step between 4 and 5:
4.5) apply a small section of thermal tape directly over the naked processor to serve as a shim - just copy step 3) by applying the same procedure to the processor, not just the memory chip
By giving the processor the same covering of thermal tape as you did the memory chip, you will make sure the tape from step 5) that lays across the metal shroud and processor, will now be flat and not have a divot, to ensure good pressure/contact between the frame and the processor when you install the frame

It's not light bleed
use search bar too
thread already here - https://forum.xda-developers.com/galaxy-note-8/help/light-bleed-t3670247
It's common. Just like every issue, not everyone has it, but quite a few people do. I think that we all agreed on a few things:
1. It isn't actually light bleed by the standard definition. It is light leakage around the bottom of the screen, reflecting off of the metal of the bezel.
2. It has been around since curved screens have been around.
3. It does not affect water resistance.
4. It isn't being caused by the screen lifting. It appears to be happening because the black around the base of the screen isn't flush with the bottom. Samsung is aware of it and they don't consider it a defect. It's more of a tolerance issue.
5. Getting the screen replaced isn't a guarantee of a fix. We had at least one person on the above listed thread that had the screen replaced and ended up with the exact same issue.
6. Getting a replacement device is not a guarantee of this being fixed and instead, you might get a device with this issue and some other issue.
7. Most cases will hide the issue.
My wife and I both have Note 8s and both of them have it. I just put the phones in cases and forgot about it. Given the number of things that can go wrong with one of these things, there's just no way that I was going to try swapping it when it is likely that I would end up with another device with the same issue and/or something worse.
Because of the nature of what may appear to be a light bleed, logic dictate to me that an exchange, or screen replacement will not keep light from reflecting off the edges!

If the black around the inside edges of the screen goes to the very bottom of the screen all the way around, then you will not have the light leakage. The reflection happens when the black doesn't go all the way to the bottom and light reflects off of the metal. This is why some people don't have it. In those cases, there is no light leaking out the bottom of the screen that can reflect.

What is this "black around the inside edges" you speak of?
Honestly, unless you getting "leakage" like this, there's no good reason to try and play the lottery. I sent it in to Samsung to get repaired. There's very little "leakage" with the new LCD panel and glass, but there's still a tiny bit, not super noticeable like before.
This is what I saw when looking directly at the screen. Yeah, it was pretty bad. You could see it during the day/lit room.

Look along the bottom edges of the screen. The actual image area does not go all the way to the edge of the bezel. All around, that portion of the screen is blacked out. If the black does not go right to the very edge of the screen, there's a very small area where light can escape and reflect on the bezel.

I'm asking what exactly is the "black" that you're speaking of? Are you speaking of the material that makes up part of the actual display? Is it the black paint on the side frame? What exactly is the "black"? Or is the "black" referring to the area where light is not reflecting?
None issue. I'd be more concerned about screen uniformity if I were a fusspot.[emoji9]

The black that I'm referring to is along the edge of the screen. It is the material that makes up the display, along the bottom edges. I don't know if it's paint or some other material.

If what you say is true, this should be adressed by samsung. Can you point me to any credible sources substantiating what you're saying?

I remember seeing it here somewhere as well. Someone even pasted in a conversation that they had with Samsung. In the conversation, Samsung basically said that it was normal, which to them means it is within tolerance. There is a much bigger thread somewhere in here about "light bleed".
I also saw it somewhere else on the internet, but can't remember where. I stopped thinking about this issue about three days after I got my phone.
I've found a pretty simply solution to this issue. Get yourself some of the glue that's included in the Dome Glass screen protectors. I know they sell similar stuff on amazon, it's UV glue or something, I'd make sure ppl talk about using it to glue on smartphone screens. Since the stuff has a really low surface tension, it sucks itself into any tiny crevices, which include the tiny concave space between the frame and the screen. This stuff blocks the light from leaking, and it's just more glue, which they used to glue the screen on in the first place.
You can use the UV light on it to cure it, or just leave it. since it's such a small amount exposed to the air it it will dry on it's own. The thing I used to hold the glue was super stuck to something the next day and I didn't use the UV light on that, so the stuff does air dry.
I noticed this when I put on my dome glass screen protector and the part where the glue spilled over had no light leaking anymore.

Hello everyone, thanks for checking out my thread :good:
As you all know, our beloved Xperia Z4 tend to heat up when doing some "intensive" work. Sure, I can live with the phone closing YouTube when it gets too hot, but the Camera app closes after taking a Full HD video for two minutes. It's quite frustrating, especially when recording a concert. That's two minutes of video and 6 minutes of cooldown.
On the other side, I just replaced my rear camera after it died from a drop. The technician glued the back cover, but I noticed that the glue was a mess and the back cover wasn't aligned properly, causing the left side of the panel to sink in. I asked other technicians if they can redo the job. However, they said maybe and no, because the back cover might crack, due to the left side sinked in.
Now, since the SoC heats up easily, and the back cover might get cracked, I waa thinking of designing a back cover made of aluminium. Basically it will act as a heatsink for the SoC while also acting as a normal back cover.
I already considered a few problems that might happen, like removing the back cover (since I believe anodized aluminium will be slippery) or making custom lenses and rubber rings for the camera and flash LED, but I wanted to know, what do you guys think? Is it a good idea?
I have bought an aluminium back cover from Aliexpress but could not test it to change of season (winter) during long delivery time.
Presently I am using a hard thick plastic back cover which stops heat reaching mu fingers and major heat dissipation is through screen only. Since I don't feel heat so I am not much worried. My phone is rooted and I am using thermal xposed module which keeps everything working in all seasons (phone has to die one day anyway).
I sometimes think of using thermal paste between the chip and phone's glass back cover but never tried it.

Late answer, but I am going to try adding extra cooling on the Z4 by adding a custom copper sheet inside with some thermal paste and replacing the thermal pad on the screen side.
