SAR value - Atrix vs. Atrix 4g - Atrix 4G Q&A, Help & Troubleshooting

Hi,
I want to buy an Atrix but have concerns about SAR rates. I may buy the Atrix or the 4g one but I have a question about it.
Under UMTS I 2100 frequency, is there a difference between SAR values of Atrix and the 4g Atrix?
Also, may I find a chart like the one attached?
Thanks in advance...

I don't know about that... It seems like the SAR value are not so popular anymore - people and manufacturers don't really seem to care about them anymore.
In any case, here's one point... You get irradiated even without using a mobile phone, because wireless networks are basically everywhere around us... One extra bit of a radiation punch in your body (from your phone) isn't really gonna hurt. But that's just me...

I honestly feel that the SAR are completely irrelevant. I'll put it this way, the sun is orders of magnitude more dangerous than your cell phone. quick physics explanations, electromagnetic waves as most know range from radio to gamma waves. These waves are not continuous like most believe instead comprised of individual photons. The power rating for radio is essentially the energy of the photons times the number of photons. So quick example say some source of radio waves produces 4 photons a sec each with one joule. The power output would be 4watts in that case. Lets also say a source of visible light produces one photon per second that has 4 joules of power. This would also be rated at 4 watts.
So think of it this way lets say you get hit with 100 foam dodge balls. it might hard but the force is distributed so it's not that bad. Now lets say you get hit with a bullet which has the same force as the 100 dodge balls. But how which one will you die from the bullet or 100 foam dodge balls.
This is analogous to the radio ways produced by your phone. it is essentially impossible for radio waves to cause damage to your body. Visible light form the sun is orders of magnitude stronger than anything your cell phone or a radio tower could produce

It makes sense, but... why is there so much fuss regarding this? I mean, if it is that simple... why do scientists still argue on this? Either for the media, either they're not actually scientists, either... well, it's not that simple... right?

Seriously, if you are not using your phone in low reception location. There is nothing to worry about.

My opinion? Fear-mongering, ignorance of science, and the media's constant hunger to feed its 24/7 news cycle. Combine that with a tendency to distort, overstate, or understate the facts (gotta sensationalize in order to draw in the idiot viewers), and you end up with mass confusion and unwarranted panic over the issues, particularly issues where science is involved.

Need remote control for headphones

Dear all,
I am absolutely looking for a cable headphone remote control for my Blackstone. The E100 headset does not work and I do not want to use a bluetooth headset as I want to avoid as much radiation as possible.
Do you know a compatible headset with remote control for the music player?
Thanks!
What you are looking for doesn't exist, and you could have really searched this forum before asking this question.
And you are kidding about the radiation thing, aren't you?

Certainly I'm not. The Federal Ministry of Health have published a paper in collaboration with some universities, showing that the daily radiation that we are exposed to, provokes health damages. Well, I think, that's nothing suprising - and we are exposed to radiation all day - so, in my opinion, we should reduce it as much as possible.
That's why I am really angry that there is no such thing as a cable remote control, as it exists (E100) but not usable with the expensive Touch HD. So where's the problem? Why not making it compatible with the Touch HD? I do not see any reason.
The problem is lack of audio in the extUSB jack. It's all going to a much easier marketed 3.5 one.

I don't want to start a flame war, but just by carrying a phone you're exposing yourself to several times more radiation than a bluetooth headset could possibly emit. Here's a quick article on BusinessWeek:
But because it's a good idea to err on the side of caution in such matters, regulatory bodies have set exposure standards. These are expressed in terms of the "specific absorption rate" (SAR), which attempts to measure the radiation actually reaching body tissue. The U.S. and Canadian governments have set a maximum SAR of 1.6 watts per kilogram, while the European Union permits a slightly higher level.
"INSIGNIFICANT BY COMPARISON." In the real world, emissions generally stay well below the maximum allowed. According to data from BlackBerry-maker Research in Motion (RIMM ), SARs for GSM BlackBerry devices (those sold by Cingular and T-Mobile in the U.S.) fall in the range of 0.25 watts per kilogram when used at your ear.
Bluetooth radios operate at much lower power levels than phones so, not surprisingly, the radiation added by a Bluetooth headset is insignificant by comparison. A study by William G. Scanlon of Queen's University in Belfast found that a typical Ericsson (ERICY ) Bluetooth radio module generates an SAR of just 0.001 watts per kilogram.
So, if you're worried about the health impact of radio waves, remember that the phone itself is a much greater source of concern than a Bluetooth headset. That's especially true because, when you're using Bluetooth, the BlackBerry is likely positioned much farther from your body -- and especially your brain -- than when holding the phone up to your ear.

There are bluetooth units with available that hang around your neck and into which you plug your headphones, like this Jabra unit. This would mean that the only radiation is at your chest and not next to your brain. Perhaps that might be a solution?

No problem, thanks for the link. Well, I'm aware of that and I know that we are exposed to radiation even if I go by train. But: You do not have to expose yourself to even more radiation if it is not really necessary and not making it possible to use the E100 cable rc is not necessary!

Yes, I've seen this one. But same problem. I really would prefer a cable rc.
I thought, perhaps it is just a software issue, that the sound is sent to the 3,5mm jack...
regardless of radiation that and wifi this and stardust that
the only thing certain in life that needs no amount of academia to prove or disprove is.......
once you hit 25 you are dying and its a non stop slide into oblivion
ooo ps:
here in the UK a little while back, some academic scare mongering types published a paper that "proved" wired headsets INCREASED the exposure to the radiation our fones emit
then again, its academia that have set up a (broken) experiment under the alps that with either do nothing or create a black hole ending the world and its surrounds
go figure?!?!
the outcome of such research, changes and contradicts itself so frequently (and depending on who is actually funding it) that all bar what is common sense (eat well, dont do "poisons" (drink and drugs) exercise etc), is pretty worthless
ive been such a researcher so i know most of its twaddle, ive generated some of it!

At what point will vzw yell at HTC for crap build quality?

Just wondering something here. How many devices do you think Verizon is having to replace/refund/take back for light leakage, dust under the screen, broken volume rockers, sunk power buttons, etc etc etc? How much money is Verizon losing over replacements getting swapped, possibly running out of stock for new customers, and losing business because people get sick of trying to find one? Will it get to a point where vzw starts taking the issue up with HTC for loss of revenue? Or am I just thinking too much about it? I've personally swapped 2 devices. And do you think HTC will ever clean up their manufacturing so we don't keep having to accept devices with the least fault simply because a replacement might have worse problems?

Honestly, this isn't anything new. HTC had this same issue with the EVO. Apple has had it with the iPhone, iPad and iPad2. Those are just the ones I've had personal relations with as I had the EVO, wife had the original iPad, and my niece has the iPad2. My coworkers had some of the issues you listed with their Droids. Nothing has changed and in my opinion, the profits companies make isn't comparable to what you think is a loss. Most consumers don't notice or care about the issue. If they do, their returned device gets sold, or given away, again as a refurbished phone.

Yeah. I guess you're right. Its just unfortunate that it has come down to this. Do the evos still have the issues even brand new ones?

The only issue I've noticed is a sunk power button. Which I don't mind since it makes it tougher to accidentally bump it while in the pocket. Plus my case helps too.
Hopefully it won't sink to the point it stops working.

I'm not trying to be a jerk or anything, but most of these "issues" that people have been having are wayyyyy over blown. I mean light leakage?

Coming from a picky person, I don't say this lightly. But most of the things that people are whining about happen to just about every manufacturer of electronic devices.If you want build quality then find someone to build a 2k device. This is merely a situation of you get what you pay for. Personally, I love my phone, and I wouldn't trade it for anything else. I've had moto's, and nokias before. Their build quality is no better than HTC(actually Moto is much worse.). Last, paying attention to build quality issues on a message board is the same as working in a car dealer for brand X and saying that all brand X cars sucks because all you have are problems coming in on those cars. We are a very small subset of phone buyers and we will notice problems that MOST people won't.

I have gotten a Thunderbolt with a blown out speaker and crooked kickstand and another with major light leakage. It was so bad it looked like there were 2 leds on the bottom of the soft buttons under the buttons. When trying to use your phone in the dark it is not acceptable and I don't blame people for being upset. If im going to shell out $600 or sign a contract for something it better not be flawed out of the box.
My phone is perfect. I might have a sunk power button but it was like that from the start so its all I knew!
Love this phone.
Not the best, but not bad
I understand that everyone wants their new $200+ phones to have been constructed to a dimension accuracy of a micron, but I guess its inevitable given the mass production process... I personally have really bad light leakage, but it doesn't really affect daily use so why make a big fuss over it? At least verizon is replacing them and not blaming us for "holding it wrong." Cough. Cough.

My first thunderbolt, the light leakage, was so bad you could see a steady line of light pouring out, forming a giant U from the bottom of the left side of the LCD, going all the way around to the bottom of the right side of the LCD, where the glass meets the bezel. I'm sorry, but when I'm paying 250 plus dollars for a flagship device, I expect a little quality control. These aren't things we should just have to expect and live with.

Exactly. At least our phones don't suffer from the death grip.
Then return it and get another one. With any electronic device you can expect a 10% or more defective rate. I'm not saying that none of the problems exist, but they exist with all phones, not just yours. You were just one of the "unlucky" 10% or so.
I'd love to get my hands on phone like the one Daniel Ocean's team procured to give to Willy Bank in Ocean's 13! Laser etched solid gold! Except Androidified! 4.3 inch shockproof screen and armed with a magnetron!
I swapped out today. It just seems unfortunate that issues like the light leakage (it may not be a big deal to some, but others it does matter) are something that people have come to expect and seem to have to live with. Especially when it seems like its as simple as the bottom of the screen not getting sealed as well as it should. Maybe I'm just picky, but ill keep taking phones back until I'm a satisfied customer.

And that's fine, the customer should be satisfied. But, there are alternative methods out there to seal the phone from that light leakage. A very small bead of black silicon should do the trick. It just seems like people expect 1000+ dollar build quality from a few hundred dollar device. If you want to take the phone back 50 times, that is your choice. However, being picky is not a build quality issue.
That is fair. But if it comes down to me having to take it upon myself to seal the screen with a small bead of silicon, that, at least in my eyes, is a fix for a build quality issue. And you are right, there is a difference between a 250 dollar device and a 1000 dollar device. However what about the folks that paid full retail for their phone? 599 I think? Are they entitled to expect more from the same device simply cause they paid more? In the end of it all, I don't feel like I should need to add a bead of silicon to seal my screen when it should have been sealed in the first place.
A friend of mine got the TB, and right away noticed multiple specs of dust under his screen. And I'm not talking about 1, maybe 2, he had a dozen or so scattered under his screen. How is that not bad QC? I know we shouldn't expect every device to be flawless and never expect issues, but some stuff just seems like it is easily fixable, stuff that the evo faced a year ago. That the Eris faced 2 years ago. And it keeps recurring in their devices.

I'm not saying you're wrong at all, but I still feel like some of the things we have to live with, are things that we really shouldn't need to learn to live with. But how small of a bead of silicon were you thinking? I'm not taking this one back, there are only 3 small pinholes of light on the bottom.

Wifi issue

Well it appears this is a design flaw!
When they where designing it they should have used some plastic! Using all metal backing makes the signal weak as hell!
Even if they can fix this problem idk! It would still be really weak!
For an example if you look at the ipad there is plastic for the Apple logo behind this is the wifi anttena!
Hopefully the back really is plastic and they did not overlook that problem! And it's just imperfections in the antenna!

I am pretty sure the Asus tech guys aren't totally dumb. I think they know about problems with WiFi and metal...
I guess the antenna is somewhere in the bezel. Anandtech (i think they were the ones) said that with their new unit wifi was okay, but it depends on the holding angle of the prime.
So it seems we DO have to take some comprises for having a full metal back. But I think I can life with that

Anandtech said the new unit was better, but not as good as the original Transformer in terms of WIFI.
Don't assume that ASUS is not capable of making such a stupid mistake. There have been lots of cases of top tier companies shipping out products with such design flaws, and I don't think ASUS is in the category of top tier company. I work in a fortune 500 company, and we get the first batch of a lot of laptops, and we test them before the workers get them. Sometimes I'm amazed at the lack of basic quality control when these devices first come out. It's like they ship out beta hardware.

There is not one doubt in my mind Asus wasn't aware that the WiFi was wearker than the TF101. However you have to realize unless the performance literally was unacceptable by whatever QC standards they have, they are able to pass the design, build the product, and ship it. Fact is only because a couple top tier reviewers recieved units that weren't up to the standards of the rest, they decided to handle the situation the way they did. In fact if they weren't aware of it, they probably would've let the stock stay as is, launch as normal, and say that "there are a small number of reported cases" as companies usually do.

This happened with Apple and the Iphone 4. The antenna was located in the bottom

http://www.anandtech.com/show/5178/an-update-on-transformer-prime-battery-life-wifi-issues
"Using Ookla's Speedtest.net web app I get a consistent 34 - 37Mbps on the original Eee Pad Transformer (our actual WiFi performance tests involve downloading a file from a local server, but Speedtest was a quick and easy way to verify the problem). My original Prime review sample averaged around 0.5Mbps, while the replacement Prime got around 10Mbps - all in the same test location. Fiddling around with location I could get the replacement Prime up to 16Mbps. My test area is riddled with challenging interference so I setup a separate test area in another room. Even after buying the same Netgear WNDR4500 wireless AP that ASUS verified 31Mbps+ operation on, I wasn't able to break 16Mbps.
I have four other APs covering my house, I turned all of the radios off as a last ditch effort. Boom - 36Mbps on the Prime.
The culprit appeared to be either my 3rd gen Time Capsule or 5th gen Airport Extreme, with those radios off and using the WNDR4500 I was able to get performance competitive to the original Transformer. Here's where things get interesting. The original Transformer was made out of plastic, through which RF travels quite nicely. The Prime's metal construction makes things a bit more finicky. Indeed this is exactly what I saw, where depending on tablet and AP orientation I'd see anywhere between 10Mbps and 36Mbps downstream (average speed tended to be in the 15 - 20Mbps range). "
I also think it's a mistake to assume that other reviewers would necessarily notice this problem. Other reviewers might not have tested WIFI performance at all.

No one is doubting the performance isn't up to par with the TF101. It's obvious it's not. Again Asus was well aware and thought it would slip by well because of something called everyday use. If it wasn't noticed by other reviewers it's for a reason, they tested it under normal use circumstances and found it to be quite acceptible. I am in no way making excuses for Asus or the design but it is what it is. Anandtech however doesn't test like that and which is why they were able to find such a flaw. It's all about a matter of usage.
I'm about to dump my pre-order. This whole release date debacle pissed me off, and now if there is possible WIFI issues...it might be a bad investment. I've been asking myself if I really need a tablet anyhow, and the answer is probably not.
please dump it.. saves it for the people who want it.

I'm glad I didn't do the pre-order thing. I don't want to be first in line for this. I'll wait until it is generally available, and there has been time for reviews of retail units. Let other people be on the bleeding edge
I have not been close to cancelling my preorder up to this point but if this wifi issue is confirmed I may be tempted to buy the original TF. Especially considering they keep showing OOS open-box Transformers for $185 on a particular website we all know and love. If I see one in stock I think I will go that route until this issue is worked out.
I wish some more reviewers would do in-depth testing on this issue.

Haven't you ever seen a proper Wifi antenna? They at least as thick as your finger.
So they NEED to make it a lot thicker.
Otherwise we'll never get a proper Wifi signal.
You may better get a different device.

Apple gets around this issue in the iPad by putting the WiFi antenna behind the plastic Apple logo, however it's not entirely clear to me where the WiFi antenna is on the Prime (I have this policy about not taking things apart until I'm done testing them).
As to why performance was lower with the Apple APs active, I'm not entirely sure. Chasing down RF interference issues can be a severe undertaking. One thing is for sure, the Prime is going to be far more finicky than its predecessor when it comes to reaching peak speeds over WiFi.

I know that the folks at Anandtech are smart people, but it seems like the reviewer conflated some things here. I don't know how much testing he did AFTER turning off the Apple AP's, but it sure seems to me like the fluctuating results he's talking about were from before he did so. Perhaps the Prime is fine in general but just had an interference issue with the Apple APs that actually resolved itself just fine once they were turned off.
Why would there be this kind of interference with the Apple APs? I have no idea, except that it would point to something in software and not hardware. But until we have someone who does a really good job of detailing precisely where a non-defective Prime has wifi issues, I'm personally writing this off to something being broken in his first unit.
True, he did say he could get it to 36Mbps "depending on tablet and AP orientation I'd see anywhere between 10Mbps and 36Mbps downstream (average speed tended to be in the 15 - 20Mbps range)"
This, along with:
ASUS feels the WiFi range does not currently meet their standards and has delayed all shipments worldwide. At the moment there is no ETA and noinformation on available quantities on the first batch.

As a comparison, AnandTech shows the Kindle Fire's WiFi maxes at 15.2, and I couldn't get close to that in my own tests.
i posted in multiple threads my concerns about the wifi issue when the anandtech and cnet reviews came out. i've canceled my preorder at jr but will keep my adorama and bestbuy preorders for now though. all hype i had for this thing is completely gone. now i'm like whatever.
If Anandtech was able to get full WIFI speed turning off other AP's than that points more to an interoperability issue that should be correctable through firmware/driver rather than antenna/hardware design.

I had a laugh at this one

Ok so i just heard the news, aparently the new iPad has a heading issue, when charging and playing games it can overheat to over 100 degrees!
Just thought i'd share the laugh, i sure did giggle at that one.
See? GPS issues dont seem so bad after all!

I think you got your units mixed up. The reports are that it's heating up to just over 100 F.
edit: I just noticed that you caught your error.
ya the original news report i heard had it mixed up, but still thats pretty hot, i wouldnt want to be holding that, or accidentally fall asleep when a game is running, might cause some damage
this is the beginnings of a huge issue down the road for new ipads. watch what i tell you. those devices won't last long St all constantly running at those high temps. people will get sick of their device shutting down on them and message popping up saying device needs to cool down. one thing about apple fans, they love to complain when there is an issue and they will let it be known. so expect this to continue to get major tech press coverage as time goes on. this could eventually become a fire hazard if its left on plugged in. device runs so hot and causes a fire or shortcircuit the wall adapter, which could cause a fire. everyday at those temps and new Ipad chips won't last longer than a few months before burning out or burning some other component up. some even reported half of the glass getting very hot to the touch. one reason could be because apple is pumping 2x the power into display to keep it running. it uses a very un-efficient way of back lighting the display. I saw it in a tech article where they broke down new Ipad display saying its good but far from perfect. Samsung has to jump through hoops to make that tricky display work.
Well, I exchanged my iPad 2 for the kids at local BB. Upgraded to iPad 3.
Few days of use and my little girl complained to me that the it actually burnt her. I guess she had it laying on her lap.
I didn't have a cover on it. I took the piece of crap back and demanded a refund. They have the old iPad 2 back now.
Apple fans need to cool off. *Badum tsh*

35°C ? Not much .. my prime is much hotter when I'm playing for 2hours withs super ips mode. Same this for sgs - 50°C or hotter. 35°C is not so much.
Wait a minute. A hundred degrees F? So a whole degree and a half higher than normal body temperature.
Is this a problem in devices the size of tablets? I'm new to tablets, but that's nothing compared with the old 939 CPU in my tower.

seriorously? that is crazy. you should've sued apple for it and let all the news media know so it can get serious press on it...lol. time for apple to be exposed. things are heating up on this issue...lmao
Ya, it can be uncomfortable for some. My prime runs nice and cool reguardless what games im playing.
I gladly take a reduced screen resolution for increased performance, not to mention the increased heat is going to cause damage to the battery.
And there are some reviews where if you have it in direct sunlight and start something intense the increased heat from just being outside can cause it to shut down!
You might not think one or two degrees makes a difference but consider if you have a body temp of 100F you likely feel really sick. If your body temp hits 116 like these ipads are getting, you are likely dead.
Anyways, i hope you all had a good smile at this, too much negitivity towards the prime on this forum hopefully this lightened the mood a little
100 degree must mean Celsius as most cpu run between 50 to 80c. 100c would be out of control lol. If it is burning her lap its more than 100f. Although, if the case is running 100f without proper cooling the cpu would run MUCH MUCH higher.

Ya, the CPU is likely much higher. The reports I have seen are saying the case itself is reaching 116 degrees F (specifically after running Infinity Blade for 45 minutes). Also, under normal usage the iPad 3 runs 10 degrees hotter than the iPad 2.
I can totally see this blowing up in apple's face (I can only hope). This may result in a recall depending on how it plays out. Because it's not just the heat thing, they are saying it is drawing so much juice while playing a game for example that the battery won't even charge when plugged in. And as others have mentioned, heat and electronics don't mix well.
I don't want to start Apple bashing, but the list of problems with the 'New' iPad put the TP problems into perspective.
There are reports that the battery won't charge:

& there are WiFi problems:

It seems that many devices can have (widespread?) issues. Unfortunately, some people on these forums seem to be exaggerating the Primes problems and it becomes very difficult to properly evaluate the situation. The problems with the Prime have been magnified to a hysterical level, I wonder if the same will happen with the iPad...?
I hope the problem with the heat is a result of the GPU. That put all of these people to the rest who complain about Tegra 3's performance. It's easy to build a big chip with such a performance. But it's complicated to control the heat and power consumption.
Icook..best seling Ipad app
Now I just have to get an Ipad 3...cant wait for the first developer to make an app called Icook, can you imagine taking a morning break from playing games, then turning the Ipad over and frying some eggs and bacon on it for breakfast!! Android has lost son??!!!

it will. Asus and prime was ever as popular as apple. so our issues were only major to us. it isn't like our issues get national t.v. press coverage. anything apple does is under a microscope. so when the mess up, they do it big. plus apple complainers are some of the loudest voices heard. this will soon enough generate t.v. coverage. I didn't even hear about the battery not charging up issue. SMH. so the reality behind new Ipad launch is really starting to show. apple will have it worse because they sell in such large numbers. meaning huge amounts of people likely to have this issue. I smell another lawsuit coming apples way. they deserve it since they always want to patent troll on smaller companies.

I heard a spokesman for Asus say that there was less than 1% of Primes that had reported problems. That's not to say that only 1% actually HAVE problems (my GPS doesn't work well enough for navigation, but I don't care because I never intended to use it for that) but less than 1% of Prime customers are dissatisfied with their devices. That seems about right to me, given that almost all of the complaints that I see in these forums seem to be from 1-2 people who got bad Primes.
To put that into perspective, I read a quote from an Apple spokesperson who said that "87% of (new) iPad customers are reporting no problems." That means that 13% are reporting problems. That is ridiculous.

[RADIATION] Note 1 vs 2 vs 3, CNET+Samsung Official Results

Introductory:
Hello all, cell phones produce radiation just in case you did not know. These radiation levels are measured in a value called SAR(Specific Absorbtion Rate) and it literally is the measurement of just the bottom line of what the human body absorbs, rather than just the amount that it radiating(ha, get it?) around the device. Radiation is bad in the human body where it is directly related to certain issues, including directly reducing bone density in the body. I am posting this as an accurate informational thread where you can draw your own conclusions based off of facts.
SAR Levels:
SAR, which stands for Specific Absorbtion Rate, levels fluctuate depending on numerous factors, in which we must go over in order to accurately understand. The key thing to understand is that the further the device is from your body, the levels begin to diminish by the milimeter(mm).
For a phone to receive an FCC certification, the device cannot have a SAR level of more than 1.6 watts per kilogram in the US, and 2.0 in Europe.
Galaxy Note Series Tests by Samsung:
Let's take a look at the Note series in order to keep this sequential and easier to remember from a timeline fashion of perspective. The Galaxy Note 1 was released first(obviously) and is the model number SGH-I717 for reference. Taken from Samsung's website directly, here are the Note 1 results, including the way that they perform their own measurements:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
You can see in this writing the methods that are used for testing, and that the body specific SAR tests have the device at 1.0 centimeters(CM), equivalent to 10 millimeters(mm) away. Keep this in mind and we'll touch up on this later.
And here are the Note 2 specific values:
And here are the Note 3 specific values:
So as you can see the comparisons above, the Note 3 effectively produces 153% more Head SAR than the Note 2, and 196% more Head SAR than the Note 1!
I would calculate the Body SAR differences but we have a big problem with Samsung's specific tests...they test these values with the device 1.0 CM(or 10mm) away from the body. This Body SAR calculation is useless to you if your phone presses against your body at 0 mm away!
Let's think...why would Samsung measure in this fashion at 1.0 CM away? Well the Note 3 produces 1.28 Body SAR at 1.0 cm away, so the big question is what would it produce at 0 mm away/ AKA in your pants pocket? Maybe it would exceed the FCC limitation of 1.6?
CNET Testing:
Now let's take a look at a recent test performed by CNET on 1/16/14 to see what they have found in differences in the Note series in particular:
The above is literally all of the information they posted where it is tough to tell how the test was performed and/or what body part it was performed against. By comparing the numbers, it seems as though they tested the head only since it matches the Head SAR values by Samsung.
But there is only but one main discrepency...the Note 3 reads 0.63 SAR value by Samsung, while CNET tested it at 0.9 SAR. Which one holds true?
Device Model Top Charts:
As you can see in the following results, our devices do not hold the highest SAR values compared to the worst out there *ehem* Motorola!
And here are the lowest SAR values amonst all devices. Keep in mind how the Note 2 is 4th lowest.
Theorycrafting:
I researched more into studies being performed per the distance of an object from humans and have found some interesting results.
Here is a model of the human head for reference, spefical model for SAR testing:
And here is are one test's results from testing the SAR levels after altering different distances:
This is just me tipping the iceberg to not go on and on.
Shifting gears toward current events, check out 2/14/14's event of the Army buying 7,000 Note 2's for its troops HERE
The reason why I feel that this is relevant is that they definitely would not want to have their troops being exposed to radiation levels higher than other devices. What makes more sense though is that they tested it for quite some time before it was rolled out, but who knows?
General Radiation Reduction Techniques:
-Consider a cell phone radiation reduction case, Google Pong research to get started since I'm probably not allowed to post links
-Consider buying a device with low SAR levels
-Keep the device out of your pocket or anywhere where it is directly against your skin. Even a hip holster might help keep it a few cm away, or carry it in a purse/backpack.
-Use speakerphone as often as possible to keep the device far from your head.
-Devices use the most radiation when beggining and ending calls. Pull the phone away from your head, even if just a few centimeters, when beginning and ending calls.
-Devices also use high radiation when "hunting for a signal". This occurs when your device has no signal, and needs to omit more power consistently to find one. So keep it away at these times.
-Bluetooth uses less radiation, but overall can be more damage from keeping it on your head for long periods of time. LOSE THE BLUETOOTH!
-Text instead of calling whenever it is applicable/feasible
-Don't sleep with the device near your head....think about it, 6+ hours of it so close to your head...
-Last things I wanted to mention are beefing up on certain things you eat.
a.) Eat seaweed, it's very powerful against radiation
b.) Look for natural supplements that particularly repair already damaged cells in your body from radiation. They are alpha lipoic acid and vitamins C and E...BUT ONLY IF YOU DON'T GET THESE FROM NATURAL DIET
Conclusion:
Considering all of the above along with knowing that we are the guinea pigs for long term cell phone radiation, I strongly feel that it's best to consider SAR levels when purchasing a device. The SAR levels are obviously increasing with each new model being released and should be monitored closely.
It seems to show as being a factor toward brain tumors and bone density loss in only 1 of 2 legs in people(where they always kept their cell phone in the same pocket). I did not go much into detail here about these particular researches/tests, but I would recommend to now start looking into the tests performed for "decade-long cell phone radiation exposures". Imagine us after 50 years of exposure, and please feel free to comment here.
Your voice and opinions matter in this world, and you should speak up since you have a right to your own opinions, and I will respect it no matter what. While I don't really know the true effects of the radiation, my opinion is that I'm open minded so I'll keep the cell away from my body to be safe. I will post this across multiple forums that it belongs in and moderators, please let me know if I happen to post this in a forbidden section. Don't censor truth, and let the thread live.
Thank you for your time reading all of this and I hope it helps. If so, please rate the thread 5 stars and hit Thanks solely to promote the spreading of the word.
Thanks for this write-up. I use a headset or speakerphone whenever possible. One of my classmates happens to have written a paper on this topic so the fear has already been instilled in me.

Oh and I just added a poll if you'd guys like to vote.
Thread cleaned of off topic banter that strays from the development plight. Move along if you have nothing to contribute.
This is a great thread. I really love that you have brought this to attention cause I will place my phone far from my body and not use it unless I have an emergency not related to my Facebook posts.

I have been doing more research into this. And I'll be honest, it worked me more and more. My kids sleep with cell phone by there head, I charge mine and my wife's next to mine. I have started to make sure we all put our phones in airplane mode while we sleep. I don't know if there's fear mongering going on, but I'm fearful. The internet usually has conflicted articles, but on this subject it seems to be way, way one-sided toward cell damage and such. I love my cell phone and its many uses a whole lot and hate to know (think) it may be harming my family and me. Sorry about the long rant.

From what I've read, the cellular antennas for the Note 3 are at the bottom of the phone. See linked image from anandtech: http://images.anandtech.com/doci/7376/Screen Shot 2013-09-30 at 3.39.26 PM_575px.png - from article: http://www.anandtech.com/show/7376/samsung-galaxy-note-3-review/7
I've always held most of my phones, while talking, from the bottom corners and resting the earpiece against my ear. Now with this phone I try to hold it from the top, near my head, and let the bottom part curve outward - about 3-4cm from my mouth.
So if anything with the Note 3 we're radiating our lips? And those of us who hold our phone from the bottom - our fingers.
Just having our cellphones 20mm (2cm) further from our bodies halves the SAR radiation. Then is it safe to assume that using this phone is better than most because the cellular antenna is located at the bottom of the phone which sits (at least for me 3-4cm from my face). So I'm getting 4x less radiation than the listed .9 rating?
That said, I rarely use this phone for calling, so during WiFi usage (which is when I'm using it mostly) my hands are at the bottom - maybe 2-3cm from the WiFi radio - and I'm not sure if WiFi is as harmful or not vs cellular?

Great information, thanks for sharing this. When Samsung performs their tests, they test Head and Body SAR at "normal operating position" which I would assume is the device hugging your cheek. It's really tough to gauge the amount of radiation deduction from keeping it further from your head, but is logical to assume that it is much, much less radiation by keeping it a few CM away from your face...and I would say that this is good practice to not have to worry and relax if you do indeed do that.
WiFi is a whole other debatable topic, where the debate is that it is hurting children especially since their skulls are thinner while it is developing.
Moderator clearly didn't agree with my comment earlier, so decided to censor it. No curse words, was on topic... I think this is nonsense, the subject of this propaganda post in general. If you think your cell phone is going to kill you, maybe it was your time.
