Hi, I'm about to buy me new S3 and I found 2 models being sold in Amazon but I'm not sure the differences between them. Does anyone can tell me the differences between these two GT-I9300RWDDBT and GT-I9300RWDBTU?
Thanks!
i think thats just software versions, as long as it says GT-I9300 you know that its a Galaxy S3, the other codes at the end prob represent firmware versions, even if you get a phone with old firmware version though, just update it Click thanks if helped
Since we are all guessing here, I'd rather believe that this code has little to do with software and more to do with hardware, like the intended market (US or EU power adapter plug) or the type of radio (if there is more than one, but since it's not LTE then probably not). No need for Thanks.
Its the sale code of the phone. DTB is for Germany, the other one, idk? Seems to be UK sale code.
So choose the right phone for your country
If u google the DBTU model it looks like its CDMA

They still sell it on the regular website and Best Buy and New Egg are still selling them on ebay. But this is very interesting that they have stopped selling it on ebay.
If they don't have any stock, how would they be running anything on eBay? I don't think ebay lets you run pre-orders and such. I'd bet it will come back up when stock arrive shortly.
It's no about stock actually.
They don't want non-US users to get the chance to buy the US model outside of the US. Which you were able to using eBay.
I was told by BHPhoto that they are restricted by ZTE to sell the device to non-US customers.
The US version is the better one compared to the international model.
Lucky me I have a buddy in NY area who got the newegg pre-order of the grey version and will forward it to me. I'm in Europe and have tested the A2017G. Sent it back as I'm waiting for the A2017U (US Model).
how is that the U model is better then G?

Easy for Unlock bootloader and easy to fix soft-brick , probably more buy those 2 comes first!!
oh ok , now that they halt the sale outside us ,seem like its just for you guys , well it should promote more and increase the community , frankly speaking just this year i heard of this brand , hmmm where has it been all these years

Could you please detail why G version would be worse than U. It is same hardware and only modem is different but modem behaves better in G as read comments anywhere? What do you expect from U? If you have software issues I am sure that if any is fixed in one of two it will be sorted out on other one too.

Actually only a few points that tipped it over for me in favor for the U version.
A: Better Software support from ZTE USA.
B: The U version has VoLTE which is supported in ROM/Baseband. The G version does not and never will. (Not supported in the modem firmware).
C: U version allows you to enter EDL mode (Qualcomms Emergency Download Mode). I need this as I'm a dev. The G version can only enter DFU mode.
D: All the band's that are required in my Euro country and in the US are supported. I travel to friends in the US and don't want to have to switch phones.
E: With the newegg pre-order you were given free headphones for around 200$. After customs it will be the same price as the G version in euros but with additional free high quality headphones.
F: My buddy tested the phone for "bad signal reception" and other faults/defects I mentioned to look out for. For over a week before sending the device over. Else I would have told him to send it back.
He is using an OP3 and even compared them as a daily driver. He said it's on par with the OP3. He even said the Axon7 is like "stuck on 4G" while his OP3 loses 4G occasionally and gets 3G only.
He is an experienced IT tech. I trust his judgement.
He is even thinking about selling his OP3 and to grab an Axon7 as soon as CM is done.

The G model has a lower volume cap, possibly due to EU regulations, while the U model has a much higher cap. The G model also seems to have more issues with bootloader unlocking, while the U model is pretty straight forward.

Thanks for the details. You see it from developer point of view mainly as I see.
A) I don't know. May be but as I see much less G related problem was reported than U.
B) May be but Volte is not as wide spreaded in EU as in US. as far as I know. Otherwise It looks that workaroud (if not the final solution) for signal issue of US model is turning Volte off, so you can get in same boat easily.
C) I don't know how important it is for avaradge users. Orherwise it is also software fearure if I understand it well.
D) You are lucky. Not eveeybody can say that US bands cover of his/her country exactly.
E) Just because of this fact US version is not better. It is only cheaper.
F) It is strange because mostly US users complain for signal reception. I haven't had any issue with. G. It works perfectly and expectedly in big city as well as low signal country area. As I mentioned earlier it looks that workaroud (if not the final solution) for signal issue of US model is turning Volte off.
Also I read that overwriting field APN manually can solve few cell issues. I did it due to orher reason and I don't have any issue.
So after all you didn't mentioned anything why U would be better for users except Volte. It is just your taste and chance to get it cheaper.

That's why I said it's only a few points for _me_ and not for _all_ users.
And as I have a chance to get all those pros for the same price in the end it is a no brainer.
Also I do not believe that the antenna is so much different to the G model. It is more likely that a few batches had a bad antenna build-in and when ZTE realized that, due to complains, new batches after the affected one's were sent off, were all build with a better antenna in place.
The Chinese and US Models were on the first batches. The international ones were produced later. Look into Chinese forums complaining about reception problems.
Unfortunate it is how the greedy corporate industry world works today. Sell those affected phones until enough users complain. If they complain, offer an exchange. If they don't they made profit.
Just look at the Samsung Note 7 disaster. Same **** is happening there.
Not to mention Samsungs Panel Lottery for their TV which has been going on for a decade.
I worked for Huawei Europe HQ and could write a book about how corporations do their quality check behind the doors. Just saying I'm never gone touch a Huawei phone because of what I know.
(Don't ask I signed an nondisclosure agreement.)
In the end it's on you to decide if you want to keep the phone or not. Or if you want to pay 399$ with more pros or 449euro for more cons.
Isn't the chinese A2017 model better than the rest? I mean... like, you know... 6gb RAM vs 4gb... 128gb internal vs 64... and you can use all the U unlocks/tools w/ no issue?
Seems that many of you forget that having US version in Europe you are out of warranty.
To many customers warranty is very important to them.
Also EU has 3 years warranty policy while US 2 years.
I'm having a month now both gold and gray G version and no reception /WiFi issue at all.
Compared to my S7 Edge the call reception is the same level and WiFi is better.
Also G version will have in coming weeks official root and boot loader unlocked from ZTE without loosing the warranty.
Even that US version is getting first the official software updates it's just matter of time(less than 1 month) until G version also received the software update for the specific region(Europe)

Just curious does the u model comes from the ZTE USA down in texas? I presumed warranty is by them as well?

You could be right. That's how the world works. You also are not enemy of your money as well as no one else.
Regarding the price I would say that EU price contains the average 21% EU VAT. So it means that price of EU version would be between $410 or 415 in US. So it is not a big deal. Also I think that EU citizens should pay duty if they import from US but it is already off topic.

Oddly enough, amazon has also stopped selling the phone. I guess it could just be sold out though.
Hm, still "in stock" at amazon.com:
https://www.amazon.com/ZTE-Axon-unl...TF8&qid=1476347129&sr=8-3&keywords=zte+axon+7
Amazon.com has gold for $399.98, but the grey (which is what I want...) is $479.00. What gives???
I see that B&H Photo sells XQ-BC62 model in US as "Sony XPERIA 1 III Dual-SIM 256GB 5G Smartphone (Unlocked)", i.e. the dual-SIM capability is explicitly claimed.
Meanwhile other US web sites (e.g. BestBuy) also sell XQ-BC62 model in US without mentioning the dual-SIM capability.
So, is XQ-BC62 sold in the US a dual-SIM phone or not?
I understand that Sony devices whose designation begins with X are supposed to be dual-SIM, at least hardware-wise. But there could be software differences, right? Or not?
---
A more specific question that interests me is about future AT&T compatibility. The AT&T's compatibility list clams support for XQ-BC62. So, does it mean that the dual-SIM phone from B&H is going to be supported? Or is there a chance that it will stop working on AT&T network after February 2022, despite being on the list?
Uh... Sorry. My mistake. BestBuy page also says it is dual-SIM. Missed it.
Everything's clear now.

As shown on GSM Arena, all model numbers of the Xperia 1 iii are hybrids. That means they have one regular sim slot and one sim/sd card slot even though only one of the two sim cards can use 5G at one time.
I did have the same experience when ordering my Xperia 10 III. On the website I ordered from. It said it would only have one sim slot. But I did some research and found out it was a hybrid, which I did confirm on delivery.

Don't count on Telco support improving. All Sony needs to do is update the firmware but that hasn't happened. Only upstream security patches and critical bug fixes (boot loops, firmware self-destruct, and dangerous overheating) have been released. I haven't seen any badly needed performance or usability fixes.

I put a post at https://forum.xda-developers.com/t/xperia-1-iii-and-xperia-pro-i-fatal-flaws.4374813/post-86157973
Many countries are releasing phones with dual sim, but there are some countries like Japan that does not provide dual sim, Many phones in Japan does not support dual sim.
What are the differences between Sony Japanese and international phones? Are there any hardware changes apart from the software changes.Why are the Japanese ones so cheap?
There are differents i think and cheap ? Because Sony is made in Japan.
But if you take two of the same type, you can see that the Japanese phone heats up and the signal decreases. I observed it closely with several models. eg xperia 1,xz3,xperia 1iii
They're not being shipped out of the country lol

How much do you want?
Differences:
1.All JP mdel support "Felica" payment(Some NFC-based stuff requires specific hardware that support it) but global model don't have these so it can't be enabled even with JP firmware flashed.
2.If you mean au/docomo/softbank version(like SO-xxx or SOV-xxx), you might not able to use it THEORETICALLY ouside Japan or with other carrier, the bootloader is not unlockable in these model as well.
3.These model mentioned in (2) only have single SIM slots and lower RAM/storage in past days, not sure if it's the same for recent model.
Why it's cheap:
SONY is pushing carrier free smartphone forward in Japan, you can purchase the carrier free model now, but I think the model you mentioned most likely to be the carrier specific model, and that's why it's cheap, I guess.

Hello,
The Snapdragon 8 gen 2 is supporting DUAL SIM DUAL ACTIVE (DSDA) . The question is the galaxy s23 ultra have that feature ?
if not , why ? and how to enable it .
Thank you
Qualcomm said that S23 series supports DSDA only in Chinese market with model number SM-S9180

Thanks for the reply. Do you have link for more details ? also, if I change the firmware (CSC) TO China do you think it will work since they have have same (SOC) and 5g modem chipset ?
There are EU regions with dual-SIM enabled for the S23 series. I would suggest trying one of those first.

Seeing how that person is in Pasadena, CA, I question if it has to be the Chinese model.
It's stupid if Samsung doesn't support DSDA but I guess at the end of the day, it doesn't really affect me, as I use one SIM for calls and text and the other for data.
Through Odin, the firmware might be interchangeable. We just don't know yet because not many of us have our devices. What made conversions more challenging in the past with Samsung devices, was the different hardware. We don't have that here for most of the world.now. The Chinese version will not have eSIM capabilities because eSIM is illegal in China. We're probably going to be waiting on a custom ROM or combination ROM to get DSDA or DSDS for pSIM's enabled on North American versions, if the pins are there. From what I have heard, they should be. My eyes aren't good enough to see in side.of.my T-Mobile version to tell though and there is no place to buy a replacement dual-SIM tray in green yet to even see what happens when a second pSIM is inserted in slot 2.
With OnePlus, converting a device to another region or firmware, like with my 8T and 7 Pro, was fairly easy. However, OnePlus/OPPO cracked down on this and removed the second set of SIM pins making dual-SIM on North American models impossible.

Interesting. This year though, no Exynos might be the game changer. EU firmware tends to be a lot more friendly for North American use from my experiences flashing OnePlus devices. This is my first Samsung since the Note 9 though. Definitely looking forward to some flashing goodness once developers start taking an interest in the S23 devices.
Edit: T-Mobile should get me my SIM unlock by launch day so I am definitely interested in trying once the SIM lock is gone on my device.
I'm glad that I was linked this article before buying an S23. Might pick up the Oneplus 11 5G instead.
