Could someone give me some confirmed info?

I'm just curious as to what it is. I'd be really interested in an android tablet. I currently have an eris... which is pretty weak.
I've googled a lot but everything seems to be old or "rumored" so could someone help me out? I'd appreciate it.

What is it you want to know?
Sent from my HTC Desire

Specs, pricing, will it be google supported, full market place?

Oh and I'm also really curious to see if anyone has tried logmein to remote access their computers. I do it on my Eris but it's slow. I've seen it on the iPad and it's much better. How is it on the GTab?

Pricing isn't announced yet in most of the world.
For every other piece of infromation, why not just, eh, check the official website? I mean, have you even looked at Samsung's website? It lists all the specs for the device and few other details.
tl;dr: Price - dunno, not announced
"with Google" -experience - yes, if you mean GMail, Market and stuff.
Full Marketplace - Yes, it's a full phone and has all the capabilities as such, even market.
ps. Aside from the larger (and different) display, the Tab is essentially a Galaxy S.

Perfect thanks.

Does it Have an FM Radio Chip on it?

sorry but just to clarify this is a full phone but in tablet format?
so the inbuilt cell is capable of making GSM calls the same as say an iphone, NOT just able to use 3g connectivity for web as say a iPad?
wonder why the camera spec is so lame?

YES.
I'm sorry if I YET AGAIN sound angry or frustrated, it's not specifically you.
But don't you people ever think of yourselves and either read the official site or google around before asking questions? Yes, it's a full GSM/GPRS/EDGE/UMTS phone. The official site lists all the bands the phone works on. (except I hear the USA version lacks the phone capabilities? but retains data/sms? I don't know.)

or head to http://www.samsung.com/ and navigate from there.
EDIT: Euro/FI version:
GSM&EDGE / 3G / CDMA / TD-SCDMA - 850 / 900 / 1800 / 1900 MHz
3G - 900 / 2100 MHz
GPRS - Yes
EDGE - Yes
3G - HSDPA 7,2 Mbps / HSUPA 5,76 Mbps

ICON AND LIVE PEACEFULLY.i am here to take all the tensions..Now hope i don't sound rude!...for more on this,read the forum rules..

yes.... i hae got it on saturday and i have made GSM calls also...
GSM calls and 3g video calls are extra features compared to ipad which will need a seperate micro sim and 3g contract and pay extra
when at home i use wifi for the tab and while on long journeys , put my existing contract sim and use it and will not miss calls too , the display is just awesome and so smooth........
i dont need to take seperate contract for stupid things

Ah, good. What I did mean about that was that the other specs are official, but that part I haven't read anywhere but "rumor" sites.

As of right now they make no note of voice calling on american advertising ... It will be in the hardware but not in the firmware (rom) but im sure If we got a copy of your guys roms (all other countries besides US..lol) we will have the voice feature.

I'm not really clued up on all this but wouldn't this be tied in with the hardware? And since the Tab has been announced in the states not having voice(and possibly sms) capabilities wouldn't that mean it was missing the hardware to do it?
If that isn't the case then it's awesome for the people in the states to potentially have that option

{Trick} Get Around "RAT SELECTION RESTRICTED" on i897 modems!

First off i need to thank Xda user KevL for putting me on the first step in the right direction to getting here! Thanks!!!
For any one using and running i897 modem for the love of audience chip support on their device and also need band selection to lock 850 band, this thread is for you!!!
I first started using i9000 modem kernal combos just for the band selection ability.
After AdamHolden85 Allowed me to continue development on his KB1 Fusion rom i started a mission to unlock the "Rat". I gathered much information from users that suffered from "Rat". (weird that some users with i897 modems installed don't have this restriction, but most do)
Some may ask "What is "Rat"?"
dial *#2263# on your captivate while running a i897 modem and you get:
{

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
but what you are after is:
So lets get to it shall we!
This is really more of a security loop hole!!
1=Remove the simcard from your phone with out removing battery!
(use your nail to lift the edge of the card over the battery lip)
2=dial *#2263# and you will first get "RAT", wait for this pop up!
3=hit "OK" and dial *#2263#, and now you are in!!
4=select the bands you wish to use
5=Menu hard key to get popup here and select end!
6=place device into airplane mode!!
7=reinsert your sim with out removing battery!!
8=Turn off airplane mode and watch cell bars grow and data to connect in your status bar.
9=Dail in *#0011# and check for your self!!
May work on other band selection RAT modems, I only can confirm JH7,JH6,JI6,KB1,and KF1!

FAQ, at OP's request
FAQ​
1.
Does this mean UL/DL speeds can be improved on those listed modems?

Johnsondr80 said:
Not there yet. But they say 850 is faster due to less users clogging the line.
Click to expand...
Click to collapse
This does not effect data speeds because this has nothing to do with HSDPA/HSUPA/HSPA+. That is dependent on something written within the modem that XDA is yet to learn about. (no one seems to wanna touch the modems, in part because they are heavy with proprietary code for things like the bluetooth chip and the GPS chip. proprietary = closed source and a PITA to mod) Tho using GSM = 2G and WCDMA = 3G, so be careful about which 850 or 1900 band you are choosing.
2.
And the same bugs with using a I9000 kernal aply, no buetooth, is that corect?
Click to expand...
Click to collapse
This does not allow for mismatch with kernels, as that is HW communication dependent. Your kernel talking in a 1234 pattern and your modem talking in a 4321 has NOTHING to do with RAT or the band/frequency that your phone it trying to speak to the antenna with.
3.
I have tried this a couple times and it doesn't seem to work for me. RAT is still restricted at the main menu.
Click to expand...
Click to collapse
This does not remove RAT, it gives us a means to work around it. At this point we still don't even know what triggers RAT as some I897 users have shown to not have such restrictions. Until we have figured that out we can't kill RAT, tho we do know it is something within the I897 aka AT&T modems.
4.
I notice if I reboot my phone it sets back to 1900 again. I made sure to follow the steps correctly three times. Is this how it works?

Unless you visit recovery for some reason and then reboot from there.

I find that if I get back on 1900 for some reason. Airplane mode for a second and it goes back to 850.
Click to expand...
Click to collapse
Settings may get dropped on reboot, sry but for now this is only a change held in the RAM.
Other things to note:​
Phone stays on and running the whole time. The most time consuming part of this is waiting for the phone to realize the removal/insertion of the sim card.
-SGS Tools / nitrality- apps have the "secret/service codes" to speeds up and or ease the process.
No love for WCDMA 900... even on fully auto that lone band is unused.
Folks, follow the instructions exact, and take your time. I tried toying around and skipping = not successful.
Lastly you can't seem to force it to run an unsupported band (like I did with the WCDMA 900), it will eventually seek its way into service again. Keep in mind that having RAT means we have limited control over this aspect of the phone.
Also, LOL that I can force it to use GSM and only have edge data

Awesome !! And big thanks for this Johnsondr80 !! And a thanks to KevL also !!

Also the 850 Band travels better so you'll see stronger signal more often. Should also give better call quality, tho I'm not 100% on that part.

I just wated to verify.....So there will still be no hspa with the i897 modems... And the same bugs with using a I9000 kernal aply, no buetooth, is that corect? This just alows band selection?

Yep, I897 modem is still hsdpa only. Yep, does not add any new kernel compatibility. Yep, does allow for band selection (tho still not a easily as those without RAT)
So, it is mainly useful for devs / testers, and ppl who have dumb phones that love using 1900 band during heavy traffic and/or low signal.

This does not remove RAT. As Johnsondr sneaks in there "This is really more of a security loop hole!!" In that you can enter the menu with the sim card out and lock in the phone to use your band of choice. When you put the sim back in it stays locked in.
Annoying yes, but at least we now have a means of changing the band when service is generally crappy.

I'm confused why do you think I posted in the wrong thread. I did your step to get audience chip support. Audience chip is suppose to offer better voice quality. Am I missing something?

did this a couple more times to make sure I went through the steps correctly and both times when going back to the menu to see what band it was on I watched it go from 850 back to 1900. This was without a reboot or any button pushes. I hope we can find something that will work consistantly.

This works, however, it does not stick on reboot.

Maybe you miss read. There is nothing here to give audience chip support to those who don't already have it. OP mentions this is for ppl who choose an I897 modem+kernel so that they can use the Audience chip.

This enables LTE on the phone. It has the physical capability to operate on LTE, however, the phone never got FCC approval for it, so LG left LTE off by default, with HSPA being the fastest spectrum it is capable off without modifying the modem and files. Flashing this package will modify your modem an build.prop to allow it to operate on the LTE Band 4 spectrum, which is what is used in the US. If you are outside the US, you will only see any benefit if Band 4 is used in your area.
Cliff Notes is that it makes your mobile data a whole lot faster.

Quick question... Did you change your sim to LTE, some of the Sims don't come prepare to LTE, needs to be written LTE some where in the sim, ask morocco carrier if they really work in band 3 and 20, If someone else has lte with same carrier check bands

There are threads explaining how to enable all lte bands on Qualcomm chips... I have tried it with Verizon note 3, 4 and verizon lg g3 and didn't work on the notes, only worked on lg g3. I think it's because of the selinux... If you can flash custom kernel you may be able to enable band 3.

Yes

Try to select from list 2G and see if the modem works. then try one of the options offered. So I managed to get 4G

I think the problem is with the modem they used in Android Pie: it supports only B1 (2100), B3 (1800+), B5 (850), B40 (TDD 2300) and B41 (TDD 2500).
So 4G is working but only in countries where this bands are used. In Italy for example we have band 3 in highways and cities, but in rural areas we use band 20 and it's gone
I hope that they can solve the problem with a new update.
PS: Don't try to flash 8.1 modem over Android Pie stock rom. It will cause system crashes and SIM card won't work anymore until a reflash of Pie modem.

I think the problem is with the modem they used in Android Pie: it supports only B1 (2100), B3 (1800+), B5 (850), B40 (TDD 2300) and B41 (TDD 2500).
So 4G is working but only in countries where this bands are used. In Italy for example we have band 3 in highways and cities, but in rural areas we use band 20 and it's gone
I hope that they can solve the problem with a new update.
PS: Don't try to flash 8.1 modem over Android Pie stock rom. It will cause system crashes and SIM card won't work anymore until a reflash of Pie modem.

It also happen with B7, at least for me. In Italy I use Iliad and.. there's no 4g available for me. 3g works but, if it's like how you said, we need to wait for the next update.

I have to say I'm amazed that Xiaomi can release a rom with missing bands. It seems so incompetent. Considering Europe in particular uses these bands and this is the market they are trying to break into it would seem another massive own goal (after the phone for £1 UK farce)!

Can you guys try to use a launcher like Nova that allows to go to activities, search for Settings.BandMode and select Automatic, and see if it helps?

Consider as well that people who have this issue have been "forcing" the update when they were not supposed to get it... You can't blame Xiaomi for that.
If some people got the OTA "normally" and have this issue, then I can understand the complains, but so far it's only people with 0 patience and disregarding the advice of others who warned about risks for LTE while forcing the OTA (and in case it's not clear for some, LTE==4G).

This is simply wrong on a technical level. There is only one version of the update. I also factory reset and the bands are still missing. It's been established that xiaomi have omitted many of the bands. If you go on the firmware thread that joey huab updates he clearly explains that the bands are missing on the pie firmware. It has nothing to do with using a vpn to get the update early!

You have to wait for xiaomi firmware update. The bands are missing.

My wife got the update ota on the mi a1 and also no 4g anymore. No vpn push or anything.
