Sound (reduced volume) since May update - Xiaomi Mi A1 Questions & Answers

So,
I have a theory that may be supported by the official announcement by Miui here:
http://en.miui.com/thread-2730552-1-1.html
There are two models of the A1: MDI2 (India) & MDG2 (Global), I understood the only difference was the MDG2 has more bands (eg It has B20 I need in UK) that are not needed in India.
I think also the MDI2 is marked "made in India" and MDG2 is marked "made in China".
My MDG2 (64GB Black) has never been affected by low volume (or hissing for that matter)
The official statement says "Special tuning has been introduced to deliver a better experience for Indian users", this suggests the change was aimed at the MDI2 only, I open this poll to see who is affected.
I added Custom ROMs in case the two models have different hardware

made in china, mdg2: affected by low volume.
this is honestly so annoying...

Purchased in India. No hissing after may update.
Version MDI2

I have the MDG2, made in China, volume is affected.

I have the same issue and it's really annoying. I think that we are not reading the annoucment correctly. Probably only the third paragraph is for Indian customers - I think they mean that all devices are affected (the first two paragraphs are for everyone) and the Indian version has even more "tuning" (the last paragraph is only for it)

Lower volume, but max volume is still high enough to drive all my headphones (I'm not going above ~70% of max volume). Hissing has been improved. I'm happy with the change.

[Q] Does the correct regional version matter?

Due to the ridiculously high price of the note 4, I have had to turn to ebay and imported versions on the note. Versions from the US and Asia have shown to have the same frequencies as we have in the UK. I am curious to know if it is okay to go ahead and buy the US or other version if it appears to share the same frequencies as my network has in the uk? I would also like to know if another regions version will have any other adverse affect e.g delayed software updates?

Personally i think you'd be better sticking with the correct model to be sure everything will work as inteneded

SAR of the nexus 6p

I got the following values from phonearena
are these legit? Because these seems very high ... almost close to the limit.
Head 1.49 W/kg
Body 0.81 W/kg
Product Specific Use 1.44 W/kg
Simultaneous Transmission 1.56 W/kg
USA figures
On an Indian website I see its mentioned as 1.18 W/kg
Sorry for the figures i posed they are north american . limit being 1.60
the phone should have the same SAR test regardless if its in India or North America. so which one is the real test result? there needs to be an accurate test done.

i found this on wiki, so i think you're right. now we just need some independent lab results:
https://en.wikipedia.org/wiki/Specific_absorption_rate#Mobile_phone_SAR_testing said:
United States: the FCC requires that phones sold have a SAR level at or below 1.6 watts per kilogram (W/kg) taken over the volume containing a mass of 1 gram of tissue that is absorbing the most signal.
European Union: CENELEC specify SAR limits within the EU, following IEC standards. For mobile phones, and other such hand-held devices, the SAR limit is 2 W/kg averaged over the 10 g of tissue absorbing the most signal (IEC 62209-1).
India: switched from the EU limits to the US limits for mobile handsets in 2012. Unlike the US, India will not rely solely on SAR measurements provided by manufacturers; random compliance tests are done by a government-run Telecommunication Engineering Center (TEC) SAR Laboratory on handsets and 10% of towers. All handsets must have a hands free mode.

Regardless. The values are pretty high!

Test results in the United States, should match the test results in india or anywhere else in the world, it is after-all... the same exact phone the testing is being done on. the results should match no matter where you bring the phone to. If any of you have any other test results performed independently, please do share !
let me ask this - if these numbers are solid, is it going to prevent you from buying the phone?

For me, and a few others I know Yes it will prevent them from buying the phone.
I had blackberry phones with high sar rates like the ones listed in the first post, and when talking on the phone .. it would heat up vs my note 3 .
So yes some people actually do look at SAR before purchasing
Checked the FCC for the tests done on the Nexus 6p. See the reports for "exposure" if you're interested. It does list various values for radiation.
FCC Link
Hi, can anyone look into manual and tell me what is the SAR value of Nexus 6P (European version), please ?
I canĀ“t find it on the internet.
Thank you very much!
1.17 & 0.54.

US & Global variant comparison

We know for sure that there is two different version of the Axon 7, the one sold in North America and the one sold in Europe (and china ?), respectively named A2017U & A2017G.
It would be great to compare the hardware of both these version to see if there is any differences (besides network bands and software) or if they are the same except in name.
Can two persons with the two variants be kind enough to provide AIDA64 screenshots of the importants category listed in AIDA64 ?
Thanks !
The hardware of USA and EU are exactly the same, its just the software which is different.

I thought I read that there was a least a difference in the modem regarding band support. I could be wrong.

China gets 2 more versions while the rest of the world gets one. Why brag about it being designed in the US and keep all the good **** in China?

Two more versions? Did they announce another model? I thought there was only the 64/4 (which is available worldwide) and 128/6 (which ZTE says they will eventually bring to the USA).

Depending on how they did the antenna and power amplifier design, they could still be the same exact HW. The 820 SoC supports all those bands, so at some level, it's just programming the chipset and ROM on which to allow.

This was talked about a little in the webinar. They had been marketing 3140, but when they talked to the battery manufacturer, they had actually done 3250 mAh so they changed the marketing material to match. Since the Chinese phones were already released at that point, I'd be willing to bet there is some piece of code somewhere in there reporting the old values rather than the new values. Or ZTE or the battery manufacturer got something wrong.

I have the 4gb RAM, 128gb ROM version. It is Chinese but seems to work fine here in Australia...
Funnily enough, some of the problems complained about by the US owners aren't present on the Chinese version with no problems on English translations ( I have language set to English).
Camera has NEVER had a problem and build quality is fantastic with no problems.
It has slight differences in appearance, the major being the gold US version I've seen seems to have white antenna bars on back and headphone jack has a white collar, mine has slightly lighter gold bars for the antenna and goes gold to black interior for the headphone jack.
Other than a few apps that I can't seem to get from the playstore (starts to download and the playstore up and closes) there doesn't seem to be much other difference...
Firmware version is B07 and model is A2017...
Oh, and on Antutu Benchmark I get around 142000 just edging out One Plus 3 for top position, if benchmarks mean anything to you...

It doesn't say "Designed in the USA" does it?

Model differences

I am looking at the different models available from the online store. They all seem to be TA 1045, however there are different manufacturers numbers.
I assume B/W stands for color.
- 11PL2B11A07
- 11PL2B11A02
- 11PL2W11A01
Any ideas?
I would also like to know the differences in these model numbers, specifically the 11PL2B11A07 and 11PL2B11A02.
It is the black version of the phone and both models are listed at a retailer's website. However, looking at the specs it shows no difference. For US T-Mobile users, the inclusion of LTE band 12 is important.
07 seems to be tunned for Northamerican networks, 02 for Latinamerican ones

What really is the difference between "International" and "Latin America" variants?

What really is the difference between "International" and "Latin America" variants?
Same phone - G975F D/S.
Latin America is for, well - Latin America.
"International" version can be EMEA, Middle East, etc.
So pretty much 3-4 different world markets and the only two differences, from what I can see, is:
1. Where warranty is given (which countries)
2. How often and quick f/w updates are being pushed by Samsung.
A "seller" from NY (top notch reputation seller. No, it's not the eBay guy, it is a major electronic store) sells a Latin America variant and also an "international" version. There is no indication on the box which is which, so if you order an International phone it can be middle east, can be EMEA, etc. The phones are 100% genuine. As I said - top notch seller that has been in business for decades.
Am I correct, or am I missing something?
Thank you.
I think there is only one international model. The Hong Kong, China, Japan and Korean models are separate variants--not international models. On the other hand, the Latin American model seems to be exactly the same as the International Model with the exact same band support and specs. The Latin American model is basically the International Model specifically packaged for sale in Latin America.
As for updates I'm not sure what policy Samsung follows. Some people seem to think the international model receives updates based on region and claim to have gotten updates more quickly by using a VPN.
I've never read anything to indicate that the Latin American model doesn't receive the same updates as the International Model so it probably doesn't matter which one you purchase.

I believe that there are different "international" versions.
The seller I am referring to is B&H, by all means a top tier reputable seller.
They offer an International version and a Latin America version.
The Latin America one comes with literature in English and Spanish and the warranty card lists several central America countries where you can obtain warranty service.
The International version - at least the one they currently have - has Arabic printed on the box (in addition to English of course), and the literature inside is both English and Arabic. This version's warranty card lists middle east and African countries where service is provided. This phone also comes with a Type G power adapter which is used in the UK, as well as some middle eastern countries, Singapore and others.
I don't have have first hand knowledge but I am willing to bet money that phones sold in Europe for example have European countries listed in their warranty cards.
Again - both phones are G975F D/S.
So the logical conclusion is that there are several international versions of this phone which are probably similar to what you stated above (packaged to sell in a specific part of the world).
In regards to the updates - I didn't mean some don't get updates but rather how often/frequent and how soon. For example, TPA (Panama) received ASIG update on Sep. 24 and then ASJD on Oct. 29, whereas European phones (BTU, DBT, AUT, for example) received ASII in between and they are already on ASJG.
