No liquid cooling. - Samsung Galaxy S7 Edge Guides, News, & Discussion

https://www.youtube.com/watch?v=IZU9U72OU5s&feature=youtu.be&t=4m29s
Samsung calling it liquid cooling, despite there not being a drop of liquid involved. Nothing but a trendy expression to sell more devices it appears.
And check out the heat discolouration earlier in the same video. I hope the Exynos handles things better.

Vapour chamber, not liquid cooling.
I mean, I don't know what you guys genuinely expect? Oodles of liquid to flow out of the tube as it would in a PC loop?
Chances are, there's several hundredths of a gram of water in there that are vaporised when heated by the CPU, moving up through the heat pipe until cooler.
Not as if Samsung would lie, although I believe it's misleading to slightly less physics savvy people who are of the belief liquid cooling should have tonnes of water pumping through the phone.
Perhaps 'fluid' cooling would be better?

Waterproof S4 confirmed "S4 Active"

Ya ya ya, every news article doesn't need its own thread...but sorry, this one does just as much as the Google Edition
Here's the link, instead of me giving you the "jist"
http://www.redmondpie.com/images-of-galaxy-s4-active-waterproof-samsung-flagship-smartphone-leaked/
...Wow, and I was about to get the sammy S4 this week too...guess I might wait now once again lol
i am so mad right now. i dont think i can exchange my phone now. good one samsung..release ur flagship that is made from plastic and release another device with the exact same specs, but with waterproofing and better build!
Itll most likely be more expensive. If that wasnt implied lol

As a Z user, I aswell am a little peeved. But all is well, I guess.
Well it says that the phone is only water "resistant" on GSM Arena, CNET & Sammobile and also that the camera has been downgraded to 8 megapixel.

Liquipel has confirmed that they will have waterproofing available for our devices.
$80 isnt bad either.

Liquipel is a gimmick when used on cell phones. It's borderline being a scam actually.
The technology is impressive and it has merits but these demos of cell phones being dunked are very deceiving, let me explain why...
First off a little history with other gimmicks. Long time ago probably before many around here were kicking they used to demo these "amazing" knives under differing brands (Ginsu probably the most familiar). They would do crazy things with them at the displays in malls, fairs, etc. One was cutting deep grooves in the head of a hammer. People would reach for their wallet in droves to buy after seeing that. I mean a knife that could cut through a hammer? Problem is no one ever really scrutinized and realized the "hammer" had a head made of lead. Lead is very soft and any iron or ss blade will cut it with little dulling compared to say trying that on an Estwing. BTW if you did try this with a real hammer (I did!) you'd find your blade about as ruined as if you took a chainsaw to a steel door.
So what does this have to do with Liquipel and their demos? Simple. They never tell you what the "water" they use really is. I'm willing to bet it's distilled water with a very low conductivity. Others that have this treatment done to their devices are reporting their device stops working after a day or two! Of course, you're using tap water which has far more minerals and therefore much higher conductivity.
It gets even worse! The average spill (beer, soda pop, fruit juice, etc.) not only is much more conductive but can be acidic, leave sticky residues which are often highly hygroscopic (which means they will absorb moisture from the air when it gets humid, becoming active again), and this is just bad to have in your phone!
Toilet swims? Don't even ask!
Saltwater which a device would encounter if offshore fishing or beach going would probably be the worst thing ever that could happen to your phone.
Liquipel can keep the fluid from wetting your treated parts but it cannot keep it OUT of the chassis/enclosure. That's where this is flawed. Once you have fluid penetration (no sick jokes, please!) your device is contaminated and will never be the same. If you want a waterproof or water resistant device you must keep the water out, PERIOD! This requires a completely different strategy starting with the chassis and any physical interface that must connect from the outside to in. Real solutions are never pretty or compact. If you eliminated the headphone jack and USB port relying on wireless charging and bt/wifi for sound, etc. it would be possible. The buttons would be gasketed like waterproof wristwatches, for example. The speaker and mic would be a challenge depending on the water (depth) rating. A meter rating would be no real issue but 100 meters would!
Finally, getting your device treated gives you a false sense of security! There is nothing worse than believing you're OK when in fact you won't be as careful and allowing your device to get dunked!

thanks, this is informative (ran out of thanks for today, so posting this
Regarding Active - it will have a smaller screen, and is only water resistant - highlighting this as I believe many people think it is also shock/impact proof.
Seidio is developing their Obex for SGS4, I will check it out once it is released, gives water and impact resistance.
http://www.seidioonline.com/samsung-galaxy-s4-obex-case-holster-black-p/bd2-hwssgs4-bk.htm
Although it is a niche product, adds too much bulk, and worsens the mic and speaker quality.
It's always about compromise. TBH if you're the active type that wants to keep your phone working the easiest way is to put it in the equivalent of a storm case. Otter makes one that's in the ATT stores. TBH that's the only way I would carry my phone to the beach. Sand gets into everything and wrecks it - fast!
I have actually seen folks at the beach using a macbook!
Don't worry, it won't be long before connectivity will be a part of life, thought reading, embedded devices, and anti tinfoil hat tech! :laugh:

According to some comments in the video, this phone is also only a dual core S4 Plus MSM8960, which is even further of a disappointment.
well you could always just but a waterproof S4 here https://www.liquipel.com/
or get your current phone treated.
I contacted them, they're still testing the treatment and it's effect on things like air gestures, etc. should be ready soon tho. I'm considering getting this done, but wonder how it effects things like heat venting, etc

Worse camera.
It has a worse camera. Only 8 pm. Although, it is much better looking the the stock GS4.
SamMobile has stated that ACTIVE will have OLED in one article and TFT LCD in another??????

[13th August] Ubuntu Edge: Infographic and Comparison with iPhone 5 & Galaxy S4

If you have any feedback you can drop it by #[email protected] or here.
Good work!
But one point is not quite correct:
The case of the Edge is not like the HTC One. It's made of amorphous metal.
The phone should get more around.
Help spred the word!
https://www.thunderclap.it/en/projects/3486
I think you should take down the audiophile circuitry thing, the low light optimized camera thing and the optimized for photo realism thing, too.
Those are subjective really, and spec charts should only compare names and numbers, not advertised quality.
The HTC One is a prime example of this. It was supposed to be amazing in low light. It sucks. All that marketing crap and all I get is unfocused blue noise.

Agreed
My pal has the iPhone 5 and it is a good phone but honestly, it feels dull. And since the 4.3 custom ROM got leaked, my interest in GS4 has piqued even further. But also needed to know, is it true what they are saying about GPU tweaking of the GS4 to perform better on the likes of Antutu, GLBenchmark etc??

They overclocked the GPU whenever a benchmarking application was run giving a 10% performance boost.
Not good for the circuit depending on thermal conditions, nor for advertising.
Canonical's phone is a difficult story, mostly because it's difficult to advertise something well when you spend 0% on retailers and advertising. Everything goes to manufacturing the phone. For once there's a possibility of seeing a phone getting made with 100% of the money going into hardware. Not just any hardware, because they promise to employ hardware technologies that are still on the horizon - those that may never reach consumers.
That said, despite all its interesting software features, it still runs Android.

But that's wrong on Samsung's part. Was going through AnandTech's entry about it and the tweaking in the code was clear as day. Don't understand why they needed to do this as the processor is pretty powerful as it is.
For the Ubuntu Edge, I hope it sees the light of the day as it will definitely make the OEMs re-think and put in better hardware in future sets.

I am still not convinced of this Project Ara thing. I still think it's a scam.

No matter how I think about it, still makes no sense. I still think people who are working on this are either seriously mistaken, or intentionally participating in a scam for development funding.
Modularity Overhead, Physical Size
This is the number 1 huge in your face problem they have to deal with, and people don't seem to be taking this seriously enough. The guy at the conference bragged about "25%" overhead, which already seems impossibly small. But even if it were true, it still wouldn't be small enough. Simple question, would you buy a Galaxy S5 that's 25% heavier and 25% thicker and 25% larger around the edges? You would not! Because no smartphone is that big! It's enormous! And it'll be over 10mm thick! Who the **** buys a 10m+ thick phone now days?
The latest prototype they have now has about 100% overhead in volume.
"Benefits" to a Modular Phone
Simply put, it does not exist, period. Remember your last phone? Why did you upgrade to the new Droid Turbo? Because it has the Snapdragon 805 chip? Or because it has a 2k screen? Or was it the camera? Or maybe? ALL OF THEM? The ASSUMPTION in the original phone block video, that people upgrade or swap phones because of a single component is simply false! Because
Firstly, modern phones are so incredibly reliable that none of the components ever get broken except the screen.
Secondly, you can replace your screen for possibly cheaper than it would cost to buy a new Ara screen module!
Thirdly, It would be stupid to put a 2k screen on your Ara phone with Snapdragon 400 SoC because it will lag this **** out of you. And who is ever going to upgrade from a 720p screen to another 720p screen?
Forthly, It's equally stupid to put a 20MP camera on your phone with Tegra 3 SoC because it doesn't support 20MP cameras! And even if it did you don't want a laggy ass camera experience do you? And neither do you want to viewfind a 20MP camera with your WVGA screen!
So, the assumptions that people would want to swap out modules, and the assumption that people change phones because a single component has failed, are BOTH FALSE! But sadly these are what the Ara project is entirely based on!
Other problems
How the **** are you going to build a centralised communications board that supports the bandwidth requirements of components even a year in the future? Without itself being ultra futuristic and expensive from the start? Because you don't want it to bottleneck your camera for 4K recording. Or you new 2k screen. Or your ultra fast LTE Cat-6 modem.
One of the biggest reasons people want to change phones is battery life. How the **** are you going to fit bigger batteries without it bulging out at a random corner and make the phone difficult to balance on your hand and a million times more ugly than the extruding camera on the iPhone 6? Because the grid is fixed and has a super small slot for the battery?
Another big reason people change phones is screen size. Well no luck here because you can't change screen size. So you can maybe change to a marginally better screen at the cost of a hundred dollars or more.
Drop the phone and have your components scatter all over the place. Or have a back cover to further increase thickness. But oh wait, you can't have a back cover because some of your components like the high end camera and big battery are bulging out in a CUSTOMISED and UNIQUELY YOURS way that you can't find a suitable back cover. Maybe you can try duck tape?
Target Market
Who is the target consumer of this device? People who don't already have a smartphone you said? How about they but a Chinese smartphone for $100 that will work just fine until the screen is smashed and have it replaced for $10? Rather than spending $200 on a mid-high range piece of **** like this and loose components because they fell off into the gutter on the side of the street? I mean these high precision engineering aren't cheap, and the end result can't be cheap either!
Maybe enthusiasts just like people who build their own PCs? Yeah good luck with the fixed screen size! What about the Galaxy S6 which is cheaper (because no need for the electro magnet and extra systems like central skeleton), thinner lighter smaller, with bigger screen and bigger battery? Now don't tell me you can swap out the GPU on your project Ara phone! As a PC gamer myself I don't even swap parts on my PC that often. Except the storage (*cough* micro SD card), and the graphics card.
Or maybe people who don't really care how their phone worked, as long as it does? Regular consumers? Like iPhone users? Yea right!
Sorry for long post. But I just don't get it.
Uh, Project Ara is a Google project...
I highly doubt Google would risk running a scam.
And dont forget it's just the first prototype. They start the downscaling once it works, not beforehand.

I think a certain category of user would, but this kind of user keep awake at night to scout the net for the cheapest possible hardware so it's a bit like selling a 20$ burger at McDonald

I know there is a prototype and I know the prototype is real. The question being raised here is also not whether it's technically feasible with limitless budget, which would be the case for the Apollo landings.
This is a consumer product and MONEY is a huge factor. I have no doubt that they could do it technically, but there is no reason to believe that such a product would be economically competitive to other products made by equally smart engineers, backed by equally rich companies.

Money is always the factor. But what you see when the computer was first launched it is a thing for very rich people. But if u see today the you hold computer In your hand. Well right the cellphone. It's the baby born from technological advancements that happened over the passage of years. Companies worked to bring down the cost of those hammer head computers.
Same goes here. Today we have so much technological advancements that has made the pace of development very high. The project at first look very alien to people but once its started it comes to life. Don't worry its Google who need to be worried about how they gonna make it that much cheap. Now to people Google glass seem very bad device though it is not. As we move toward future things and uses will start getting clear. So just let the things have their way up to the end. Google is not small company who bet without thinking anything on Ara. Well now Google holds the patents from Motorola. People questioned why google acquired Motorola. Well for patents for sure....why Microsoft bought Nokia just for their patents. Its money....

Tell us about your daily driver

So as the title suggests, let's hear about your current daily driver, how do you like it so far? What kinds of features do you appreciate most? What do you think is missing?
Also, let's talk about your least favorite devices as an added hono bonus.
Might as well get it started, my current daily driver is an LG V30, H933 to be exact. It's a very well rounded phone, and for up to 90% of the tasks, it's managed to replace my laptop. Battery life is more than enough for me, even with brightness set on auto and screen resolution on 2880 x 1440, the cameras are real nice, and the wide angle shooter is just addictive to mess with, great stock camera app too. Audio quality is superb, I just love the HiFi quad DAC and even the speaker is well above average imho. Finally as expected from any flagship, performance is great, and while activating battery saver mode does introduce a difference, for most tasks you still don't notice much lag.
I'm gonna say I appreciate the ip68 rating and the ruggedness of the phone, it's already taken a small drop and survived no problem, but that was enough motivation for me to get a UAG plasma case. I also put a screen protector on it initially, but dust kept accumulating around the edges and eventually making its way under the protector I got fed up and removed it. As long as you have a decent case that has raised lips both the front and rear glass should be fine, but now I never keep the phone in the same pocket as coin or keys.
Also it turns out that in case you damage the glass, it's quite cheap to replace (15 dollars from what I've heard).
As for phones I never see myself using as daily drivers, the latest iPhones certainly make the list. On top of almost complete lack of customizability and control over the phone, lackluster stock camera apps for (a photographer like me at least), and ridiculous pricing, Apple's desperation to sell their phones (or rather force them down your throat) is becoming pathetic. The 8 and 8 plus are rather fragile, and the iPhone X, while admittedly better, isn't better by much, and the worst part is that if you crack the glass on any of these phones, it'll cost so much to replace if you don't have apple care, you might as well just get a new device, which, in all likelihood, is exactly what Apple wants you to do. Between that, and introducing OS updates that intentionally throttle the performance of their older phones, whatever little appeal Apple's devices had, is now imho gone.
Another phone I would avoid is the Motorola moto z2 force/play, the plastic screen not only feels cheap, but is also very prone to scratches. The moto G5s plus is a better budget device than the play of you ask me.

Built-in Cooling solution

Considering Samsung is marketing the Note 20 Ultra as a gaming device too (XBox Cloud), heat would be another factor that may impede its performance.
Basing from this teardown video, there appears to be no built-in cooling solution for the Samsung Note 20 Ultra??
UPDATE: NOT ALL cooling system are the same for the Note 20 Ultra!
Can anyone share what you can do on this phone that heat becomes a serious issue that actually affects performance? I'm wondering what I would change in my day to day use that would trigger any cooling problems on this phone? I never considered heating to be an issue before on any phone I've used? I guess you have to be gaming everyday on a heavy game or something?

I wouldn't even say gaming. I've ran cod over dex for a few hours without issue. I have seen someone recording 8k that reported they got a cooling warning.

If you live in the desert it can be an issue especially. Sometimes wayward Samsungs will also run hot because of conflicts, bad apks etc that need to be corrected. Charging at temps above ambient 95 F can do it too.
Simply wrap a damp microfiber cloth around it to cool it... water proof phones are a beautiful thing.
I try to keep my battery temp below 100 F and above 80° when charging; the former to prolong battery life and the latter to prevent Li plating.
I also have a real time milliamp meter amp running so I can see what's going on as it reflects the cpu usage as well as diming out power hogs.
I mean it looks to me there is a large vapor chamber - those heatsinks are very big and there is a thermal pad interfacing with that copper plate on the back of the phone. Didn't see an exposed die
Rewatched the video and it appears there's the vapor chamber and the graphite thermal pad. I was expecting a more 'complicated-yet-efficient' implementation of a cooling solution. But of course, this is no Asus ROG or Nubia Magic phone.
Well, apparently NOT ALL Note 20's have the vapor chamber. Some only have a graphite thermal pad. This is something, Samsung! WHY???
I'm experimenting with the phone, recording 8k video the phone gets pretty damn hot. CPU Monitor is reporting up to 72 degrees Celsius for CPU, 45 degrees for the battery. Anyone knows what the safe range is for the CPU and the Battery?

I don't know, but the phone as a security feature, when gets really hot it warns that gonna close some apps and functions.
Is that exynos or snapdragon? I assume it's exynos lol but that the standard.

Maybe... so why Samsung don't make a flagship equal for everybody? First they give exynos in some markets, now they randomly sell different cooling systems [emoji23] you have exynos with chamber and graphite, and you have snapdragon with chamber and graphite.
It's like a lucky shot [emoji2357]

Snapdragon gets Vapor chamber cooling (like most of the high end smartphones) and Exynos gets Graphite cooling. :silly:

No, as far as I know, there are snapdragon also with graphite. It's Samsung Russian roulette playing with costumers money.

This is a bit dramatic isn't it? Last year Samsung told us all Bout the copper vapor dohicky and everyone was all the rage over it.
This year we find out some phones have graphene pads. Well Samsung never told us how to feel about these so they must be worse right? Well turns out graphene pads are better. So on one side the copper vapor whatever was so cool that people thought they were getting screwed by possibly having the graphene pads. But once everyone understands their performance they will be mad about last year's cooling method.
Seems like a lot of people are being a little dramatic and reactive with zero in the way of actual tested performance to back it up.
Is it weird, yes. Is it Cooling Gate 2020, nah.

I'm not being dramatic, all I want is that my flagship that costs around 1330 euros don't become a stove to fries some eggs after one hour playing or recording 8k video 10min.
What is absurd is that Samsung for the same price have 2 SoC and 2 cooling systems...
With exynos you always behind with graphite or other thing.
Is bulls&%tting the costumers specially exynos regions.

Yeah cooking food on the back of your phone isn't dramatic at all.
I'm gonna wait for actual numbers and avoid uninformed outrage.

Yep I'm waiting to, at least until end September.
One thing is sure... I will import one snapdragon to Europe, [emoji23] no need to wait to see exynos gonna lag again behind, even more now with 865+.

I wonder if the graphite "pad" is actually a graphite foam vapor chamber. You noticed in the teardowns that the graphite "pad" is incased in what looks to be plastic. When it's cut into it looks like under the initial graphite layer the inside is more of a squishy type of graphite substance, like foam or mud.
Something like this from a quick search:
https://asmedigitalcollection.asme....Chamber-for-Chip-Heat?redirectedFrom=fulltext
According to the paper it has about twice the performance of a traditional copper vapor chamber. The paper is back from 2006 so maybe they finally figured out how to implement it right or cheap enough to mass manufacture, who knows.
I want to add, my phone (US SD) doesn't get hot at all. It gets maybe warm when I'm playing games but never uncomfortable. Not about to open it up though lol.
Graphite in general has better heat conductivity than copper does, but both of them are generally connected to something else that will help dissipate the heat, like the case of a vapor chamber it would be the liquid inside. If it's just straight up a standard graphite pad I would suspect it dissipates heat worse than a copper vapor chamber. It might pull the heat faster but there's nothing else (except the back of the phone) to help dissipate the heat. If Samsung was planning on having the entire back of the phone help dissipate the heat then that would be unfortunate for consumers holding it.
Apparently Samsung is using both interchangeably on all Note 20 U variants.

They still got it wrong that JerryRigEverything had a Korean snapdragon.

They're saying both are being found on all variants ie Samsung is using the two heat pipes interchangeably.
If so any of the phones could have either one depending on the batch not the processor variant.
Only a tear down would tell.
