SAR values - Xiaomi Mi 9 Questions & Answers

So this is the sar values for MI 9
The highest SAR values are as follows:
Model M1902F1G
EU
2.0 W/kg (over 10 g) SAR Limit
Head: 1.389 W/kg
Body: 1.301 W/kg (distance 5 mm)
USA/India
1.6 W/kg (over 1 g) SAR Limit
Head: 0.99 W/kg
Body: 1.04 W/kg (distance 10 mm)
I'm bit disappointed with head scores in Europe.
Does any one know if you set USA or India in phone region, for someone that lives in Europe, if we will restrict SAR max to the ones used on that regions.

Max for EU is 2.0, it was 1.5 few years ago

Is there a opportunity to reduce the sar value?

I'm also curious whether setting US as the region from start will decrease the SAR values. Has anyone been able to find out anything more regarding this?

LTE Channel Question For Cellular Expert

I am planning to buy a MX2 for use in China. Apparently, the MX2 supports LTE Channel 3/ 1800 MHz. China Unicom (in the area I'll be traveling in) supports that frequency. The Wikipedia Page for "planned" LTE (although it says "In Trial", I've verified they have it in the city I'm going to) is as follows:
http://en.wikipedia.org/wiki/List_of_planned_LTE_networks
Under China Unicom LTE Channel 3 1800 MHz FDD they have a "note". It says:
(↓) 1755 – 1785 MHz / (↑) 1850 – 1880 MHz
I have no idea what that "note" means. Is it implying some "varient" of LTE Channel 3 that perhaps I won't be able to get?
I would greatly appreciate input on anyone who can shed some light on this!

Note 8 SM-N950N (Korea) Deep Blue Sea - 256 GB & LTE Frequency

Hi Guys,
I am purchasing Note 8 SM-N950N (Korea) Deep Blue Sea - 256 GB from a reputable seller on eBay.
The seller wants me to confirm the Bands / Frequency Support, listed as:

According to Wikipedia for my carrier in Canada (ROGERS), for LTE - it lists the following:
Frequency Range: 700 MHz Lower A/B/C
Band Number: 12/17/13
Protocol: LTE
Class: 4G
Frequency Range: 1700/2100 MHz AWS
Band Number: 4
Protocol: LTE
Class:4G
Frequency Range: 2600 MHz IMT-E
Band Number: 7
Protocol: LTE
Class: 4G
So, from trying to understand the chart from what the seller provided and what is supported by ROGERS, LTE should work without any issues correct?
Please advise.
Thanks.
Looks like the phone does not support band 13
Yeah it looks like you will have 4 7 12 and 17 so it will work as long as you don't go to an area with only band 13 available
i still don't know where i can buy a n950N from the US

I went the ebay route. I think I used the same seller Kalm_Traveler also used (falling_in_seoul) (~200 feedback).
After I got my package thursday the listing was taken down by ebay. Seller doesn't know why, and I can't leave them feedback. If anyone's curious from this seller the Shipping was less than 36 hours via FedEx (Korea > Alaska > Tennessee > Missouri > mah hands!) while it was estimated to be a week or so. Sealed box, even included a power plug adaptor (didn't need but was a nice thought if I didn't have one already).
If I didn't get the korean deepsea blue with 256gb internal storage I would have purchased from Never-MSRP and been very sad at having no OEM Unlock option (not seller's fault).
Thanks everyone for the response.
I'll keep an eye out and update on the performance once the device is delivered.
I've owned every Note ever made except for the Note1... my dream is always been to have a 6 gigs of RAM 256 GB of storage with an external SD Samsung Galaxy Note. The phone just came out but it's a Korean version and it's in the deep sea blue which I wanted anyways cuz I always get a black phone. So I ordered one on eBay myself. They were going for about $1,380. But I got a seller down to $1,000. My order was placed yesterday and now it should be here in the next two weeks and I will give updates as to how the service and everything else works. I also wanted an international version due to the fact that it has an EXYNOS processor which is easier to root as well. So hopefully if my phone works on T-Mobile in the United States and I achieve root I will have my dream phone. After the Note 7 Fiasco last year I've had a rough ride with Samsung as they made me argue with them for almost a hundred fifty hours just to get my International Note 7 through the claims department. Then after they took my phone back in March I still have yet to receive my check for $980. For the last 3 weeks I've been arguing with them on that matter and now they're claiming the checks in the mail. But we'll see. Then they gave me two promo codes to buy Note 7 from Samsung website because I actually purchased two notes Evans last year one international and one from T-Mobile. And guess what? Neither one of the promos worked! Then after 15 hours of calling for the last 2 weeks I've been told to do numerous things to get new promos from going to T-Mobile and having them print out my receipt taking a picture converting it to a PDF format uploading it to my desktop and then sending it to them through a link and doing the same thing with my eBay receipt. To creating a new email so that they can send me new links to the new email which I did and I've still never received any links. At this point in my life I hate Samsung as a company from the customer service aspect I really hate him with a passion because of the way they treat people. But, the only phone in the world that I like happens to be the Note line.. so it's kind of a love-hate relationship at this point. I used to talk on my Apple friends out of their phones and trying to get Samsung which I will not do anymore and I will not defend the company anymore nor try to persuade people to try a Samsung device. Just because of the way they treat people. But I will still continue to buy my note phones every year and hopefully get to enjoy them without incident. That aside I didn't mean to ramble on. But as soon as my phone gets here I'll let you guys know how it works with Tmobile service

I also bought this model, but It is looking not work on Freedom mobile 3G network. I'm so confused on that. LTE works great so far. I can't make a call and receive a call. Only can use data and message.

Please confirm which frequencies the 4X (global) has?

Hello, my Redmi 3S couldn't get 4G in Japan, while another Android did. From what i captured, the 2100mhz frequencies was the difference. Though i may be mistaking. So which frequencies does the 4X global version has?
Try using this? This worked fine for me
https://willmyphonework.net
EDIT:
Found this on GSMArena
not sure which model this is though
Your info applies to the versions made for China, Malaysia, Pakistan and not "Global Version".
The global version is advertised with the following LTE frequencies: 800/850/900/1700/1800/2100/2300/2600MHz
Whatever it's advertised with, it may come with different features.. The Redmi 5 was advertised with NFC and in the end doesn't have it! I checked that website & it says YES i should get 4G in Japan with Docomo for both 3S & 4X.. So this is not accurate for me!

How do you tell if global variant is version a or b?

After no one could answer this question properly,
I found out more info on it myself and find the following information to be 100% accurate. Here's the only way to find out what it is. Tested and proved by asking for pics of manuals in the box from sellers, and asus support.
Triangle box alone doesn't mean anything. If Model number on the bottom of the triangle box matches taiwan( ZS661KS - 6A015TW) or U.S model number (Not released yet) and box says 512gb + 12gb or 16gb ram, it is guaranteed to be version A that has all the bands for global use.
If triangle box is any other model number, there's a 50/50 chance that it will be a or b. Only way to find out is by going to the bands page in the manuals in the box.
If it says tencent and comes in a rectangular box, it is guaranteed to be version b with less bands not recommended to use on U.S carriers.
If it says 865 (not 865 plus) in triangle box which is the strix edition, its guaranteed version b.
Here's a pic of version b bands inside global variant of 512gb 12gb ram rog phone 3. Zs661ks-6a026ww https://ibb.co/3zM1sLm
https://ibb.co/LPT9pS6
Another way of knowing which model comes in both version a and b is by going to the asus website and changing the region. You'll see only taiwan and u.s has version a only models. The other regions come in both a and b versions so again its a 50/50 chance with those.
Good luck purchasing the phone. I went ahead with ordering oneplus 8 pro over the rog 3 for my needs
Seconded. I would also like to know this, since apparently the SKU isn't going to say (mine has the SKU of 6A027WW, which Hong Kong's Asus store's website assures supports US bands, but I'm still a little concerned since mine's also apparently supposed to be a Strix phone when it doesn't even mention Strix on the back).
There needs to be a guide on how to tell which phone is which. Tencent? Elite? Classic? Strix? 8/12/16GB RAM? 128/256/512GB storage? A or B version?
For Tencent, it is easy. There's only square box and it will say Tencent on the box. All Tencent sets are version B.
For ROG Phone 3 (865+), the square box is version B and 6 prism box is version A. For Strix, both square and 6 prism boxes are version B. There is no version A.
How to tell between Strix and ROG Phone 3? See the box label. It will say 865 or 865+.
All Global variants are Version B.
American market version is Version A (more network bands overall)

That's wrong. I emailed asus and they said it should mention the version on the box. Also, the band support is written in the manuals in the box.
There's Version a and b in the global variants for Hong Kong, Singapore, and like 2 other countries. A version a only model is only for u.s which is not released yet, Taiwan and germany. This does not include the tencent or strix models. Those are seperate.

Go to asus website and change the region to Singapore. It should list version a and b. I confirmed it also by asking ebay sellers. There was a specific seller with the Singapore model because I checked up the model number who checked the manuals in the box and sent me a picture confirming it was version b.
I researched everything I said from asus website, confirming with ebay sellers that were in possession of the item and now have shared my results above since no one knew the answers.
In the end, I went with ordering the oneplus 8 pro because it was ip68 rated and could not find any water resistant cases to use on the rog for the gym. Good luck guys.

That doesn't mean they're all version a. It specifically mentions versions a and b so that means it could be either of them.

Asus SG is just plain lazy to modify the spec sheet. They copied and pasted from Asus global spec sheet, changing only the Memory section. Ebay sellers? Likely to be scammer. Asus SG only distribute version A. There are lots of export set floating around 3rd party sellers in Singapore. Asus Singapore model is ZS661KS-6A026WW.

Like I said, the seller sent me pictures of the box and manuals for ZS661KS-6A026WW and the manuals inside showed band support for version b. The seller had multiple in stock and sold many with good ratings. I already did all the necessary research and contacted asus and they told me to check the box and manuals. So yes, I'm right. There's version a and version b for some of the global variants including the Singapore variant.

Well, user manual in the box is the same for all.
https://www.asus.com/us/Phone/ROG-Phone-3/HelpDesk_Manual/
Take a look at the US english manual. It is not version A. So does that means USA does not have version A?
So does the ebay seller have a "Version A" set with the full RF bands listed in the user manual?

I'm in Malaysia. Asus Malaysia also seems to carry both Version A and B. But we also get the lower end 8GB Strix model.
I was told that only the Strix version is Version B while the other ROG models (prism box) is version A. However like I said I cannot get a consistent answer for this. The best I can get is that HK Asus site lists my SKU (ZS661KS-6A027WW) as supporting the necessary bands. Seems that whole of Asia gets the WW version.
Is there a way to figure out if the ROG 3 is "version A" or "version B" based on the retail package info, prior to buying the phone?

That's just 1 or 2 models translated in different languages. If you change region on asus website, you should see a couple of different models with different manuals. Just send the seller a message asking for the bands specification in the manuals if you're buying a global variant. If you want to be sure you're getting version a, buy the taiwan or the upcoming u.s model. Both only come in version a.

Does it smell like Samsung Note 20 copper vs graphite again?
My local Asus said they do not know and have no info on Version A or B.
If its in triangle box its A version. Its simple guys. Stop overthinking it.

Wrong. Triangle box alone doesn't mean crap. If Model number on triangle box says 512gb + 12gb or 16gb ram and matches taiwan or U.S model number, it is guaranteed to be version A.
If triangle box is any other model number, there's a 50/50 chance that it will be a or b. Only way to find out is by going to the bands page in the manuals in the box.
Proof is a guy sent me manuals inside triangle box of Singapore global variant and bands matched b.
How do we know which model number refers to which country?
Also, aren't all CN (tencent) models same as "Version B" network bands?

General Why doesnt anyone ever talk about the issue of radio bands across S21 range (and all Samsung)?

So I have the s21 ultra. Love it and hate it as only a fanatic can. Have owned every Note, and am eagerly awaiting the s22 ultra. I spend time in Europe and the US and it drives me crazy that there is no version of the device that has the correct 5G and LTE bands for both areas. I have the sm-G9980 (HK snapdragon) which is dual sim and gives me 5G in Europe... but not in the US. All the 'U' versions have the US 5G (of course) ... but don't have the correct 5G bands for Europe. The 'B' is good for Europe but not the US 5G. The list goes on. It's not an exynos v snapdragon issue as the 'B' (exynos) and the '0' (snapdragon) have the same bands.
Meantime ALL Apple devices and the new pixel 6 have all the 4G and 5G bands for both areas (and I bet there are other brands that do too). I bought, first the 13 pro and then the Pixel6 pro, hoping I could adapt because connectivity is high on my needs and these devices are flagship and should be alternatives, and I really tried to adapt to them. But I returned both as I'm just not an apple person (and let's face it the devices have the same feel for the last few years), and the pixel 6 pro, which is nice, is just too stock for me, and it lacks the 'refined over the years' software of Samsung (and I just can't find a better email or, to a lesser extent, calendar app than Samsung's).
It is incredibly frustrating.
Surely Samsung can also create a global unlocked version with all the global 4G and 5G bands? I can't be the only one wanting this, or am I?
Because carriers, and because Spectrum licences are expensive.
But that's not true : even Apple doesn't have the same bands between the US and the rest of the world.
>> Even Apple (for the iPhone 13 Pro Max) has TWO modem versions, and the iPhone US model is the only one with mmWave (the "best" 5G).
Apple doesn't makes "carrier" versions of their phones - A verizon iPhone is absolutely the same as a tmobile iPhone, so by including more bands, they can move stock around the world and just add the box in the country it will be sold without excess stock when no one is buying a verizon iPhone 12 after the iPhone 13 is out - they ship it to Africa or India and boom, that Verizon US iPhone is now on a different continent.
Apple also makes cheaper phones with higher margins (iPhone 13 Pro Max 256 Gb with only 3x telephoto = 1400$, S21 Ultra 256 Gb with 3x AND 10x telephoto = 1100$) so spending 1$ more per phone on spectrum licences to avoid creating different models is a complete win.
Because of carriers, most Android manufacturers have 3 versions (US, Global, China) with different bands supported, sometimes different modems, even different antennas.
Just to be clear, I haven't heard of anyone "unlocking bands" as it could be done 11 years ago (even rooted etc). It is now much more secure (modem firmware) and most model are missing MMwave antennas anyway.
TLDR - not true, even Apple has mmWave only on US versions. However iPhones have the largest bands supported on average.
Website kimovil has a really good band comparator, you can identify 5G bands in the US and in Europe and find a phone that supports both. Only the US Oneplus 9 Pro seems to do it as of now.
Thanks for the response. I will check out kimovil. It makes sense why the Pixel would have the bands too.
Life is about compromise!
