(Q) HD Voice - G2 Q&A, Help & Troubleshooting

I have an unlocked ATT G2 and am using it on T-Mobile, is there Stewart to get the HD Voice activated on this phone?

Besides flashing the t-mobile software, I'm not sure. I checked the build.prop from some ROMS and the line for HD voice is not on any so it may be built into the audio files somewhere else. Not sure if a t-mobile firmware will work on the att g2

I don't think you'll be able to use HD Voice. From what I can tell it requires the 1700 mhz band, which hd voice works off of on tmobile and the AT&T version of the G2 is lacking that band.

That's not the case. T-Mobile's HD Voice (or AMR-WB) is simply another codec that's supported in the radio. Even though it's bitrate is fairly modest, T-Mobile only supports it when the user is on HSPA/HSPA+ -- regardless of its RF band used (ie: no EDGE/GPRS, despite that it would technically work).
Now -- whether something needs to be tweaked to get the radio to cough up the codec -- that I don't know. I do know that unbranded, non AWS (pre T-Mobile) iPhone 5's support HD Voice without any modification, so there isn't anything proprietary that T-Mobile needs to do to a handset to provide support.
Interestingly, a T-Mobile branded G2 will clearly display a yellow "HD-Voice" icon in the upper left corner of the display while in a call. To the OP -- have you called another known T-Mobile user that has an HD Voice handset, while you're both on the T-Mobile network and both on (at least) 3G?
also, don't use a Bluetooth headset while trying HD Voice out. You need an HFP 1.6 headset to get HD Voice via BT. While the handset will still negotiate AMR-WB properly, older BT headsets munge the bandwidth to the point that it sounds like a non-HD call.

Phone capabilities?

I am very interested in the galaxy tab but I am wondering if it makes and receives calls on the carrier networks, namely verizon. I am one of the people who will lug the tablet around as my main phone. I see the phone app on the pictures around the net but I have yet to see it stated anywhere.

You will be sad to know the for the North American Tab the Phone/ Voice has bin removed from the list of options thats is being shipped from from Samsung. In the press conference today they stated that.
If they kept the microphone, this is Dev worthy.

no joke! i hope someone can get ahold of one of these ASAP and take it apart to see if it has the hardware.
I read somwhere that you just have to have a bluetooth or regular headset.

I'm hoping this is just a software thing for having the phone feature disabled on the US version of the Tab.
Imagine the looks you would get holding a 7inch tablet to your ear? LOL. Well a wireless headset or a set of earphones is in serious need. Hopefully the devs here can sort something out if the tab has the hardware for it.
it does have 3G voice and data hardware

Well that is awesome then, I will go back to the idea of me wanting one again... Ill use my g1 until a modded rom comes out if one isnt out by the time it releases stateside...
I dont plan on holding it to my head during a call even though I might just to be funny..lol.. i barely use my phone (for voice calls) which is why im so concerned with merging it into my tablet because it would be just an app for me... which is the way I like it.
Every review I've read of the US-based versions of the Galaxy Tab (for AT&T/Verizon/Sprint) has said that the Tab will NOT work as a phone.
(sorry, newbie post so I can't post full URL...endgaget has the story)
Skype and other VOIP services work, but not regular EDGE/3G phone calls. Combined with the so-far announced pricing from the major carriers absolutely kills any desire for a Tab vs. either an iPad or a Dell Streak. I'm hopiing that some vendor will make a 7-9" tablet/phone combination in the near future.
That's the American version of the GT. The European and Asian GT DOES HAVE calling/3G functionality.

So, if I understand this correctly (?) unlike the iPad where it's 3G cannot use voice but only data, the G-Tab Euro version can connect via voice and make calls, but the US version cannot.... Does this mean the US (north American) model lacks the hardware? I am asking because the voice calling is important to me and I have ordered an unlocked US version but maybe I should go for the Euro version?
Euro tab - no 3g in USA but it has voice capability
Has tab - data and sms/mms and no voice capability
Pick your poison muchachos.
I am personally think about the Sprint version with 2gb/m for 399.99 and 29.99/m.
Why wont the Euro version have 3g? The unlocked Euro version from cellhut and Negrielectronics have everything we need. Should just pop in my AT&T SIM and off I go.

cellhut.com/Samsung-P1000-Galaxy-Tab-Unlocked-Quadband-GSM-Cell-Phone-Reviews-29956
If the tab has 3g radios, wouldn't there be a way to transfer voice over it? Of course some hacking would be needed, but i'm sure there is a way. If not, couldn't one just tether to the tab with a phone and then use that to make calls over a "wifi" signal?
To answer to the two previous posts:
Unless the Tab has the ability to change 3G bands (Like its cousins phones from Samsung line), the European version won't be able to have 3G over AT&T (Maybe T-Mobile if I recall well, not sure). However some other versions may be able to do so (The version from Telstra should have the right radio for instance and hopefully voice calls enabled)
Then... hopefully we may not be limited to VoIP on the US Tabs... I hope Samsung didn't really castrate the Tabs here and limitation is just a Software limitation. Just flashing the right Firmware / ROM could restore this function (But then you'll need a different plan than the one your carrier will let you subscribe)
All in all my plan (and hope) is we'll be able to enable the voice calls on the US versions. I'll buy it with no plan and will switch it with my TP2. If not... Then I'll be looking for a version elsewhere in the world that has the proper 3G bands and voice enabled

That's my thought as well. I purchased the HTC HD2 and used it w/o problem on ATT for more than a year even tho ATT never did specifically support it (which meant I could only get Edge speed - but the GT has 1900 UMTS and the full range of ATT voice GSM freq so it should work OK.
i bought the tab in germany and calling even without headset is very good.
the speaker quality is very good. makes it a brilliant conference phone
I seriously hope that the it is just a software lock because buying a the overseas version vs the u.s. Is a huge price difference , looking at the frequencies of tmobile u.s.a will the overseas version work on 3G here even though tmobile is 1700/2100 ?
When I use aDialer I press # and the number I try to call and it cuts off music and for a second a call icon pops up like something is trying to make a call then ends. If I dont hit # first then it doesn't even try to make the call

*Request* Wifi Calling for AWS Streaks?

Is there any hope of this working for the AWS Streak? Us AWS owners seem kind of few and far in between, so I'm not sure if this has even been addressed.
I know there have been some phones that never came with the app, nor were meant to ever have it (Nexus One for example), and they now have Wifi Calling. I'd be willing to give a pretty generous donation if anyone could get this to work.

Do you mean you cannot do it using Skype and Fring and so on?
Some tmobile branded android phones have a feature callled wifi calling which basically makes the phone a microcell. Regardless of your cell signal, you can make calls with your regular mobile number. The app is a preinstalled tmobile app, but has been made to work on some non tmobile branded android phones.

OK, and your on T-mobile, so have you tried installing a apk from one of these threads?
As its T-Mobile specific and sometimes hardware specific, unless someone with a T-Mobile AWS streak posts the apk for you, your not gonna get this working, if all else fails there is always google voice, skype and so on.
According to this thread, it will not work.
Im pretty sure its not hardware with android phones. Some of the android phones that currently support wifi calling were out way before they made the feature possible with android. The nexus 1 for instance, was never intended for wifi calling, but with some tweaks, they got it working. From my knowledge, the only real limitations for android phones are aws bands and a tmobile sim.

[Q] TOUGH question - which S4 for the Brazil 4g TIM Network

4G LTE has finally rolled out in Brazil.
To start though they are using what they call a 4G LTE 2.5Ghz network until their 700 network comes on in another year (or two).
This network is finally available and if I am going to purchase a new S4, I want to make sure that this new S4 will work on their network. Currently the 3g I use gets (as per speedtest.net) download speeds of 0.25mbps and upload speeds the same 0.25mbps. Yes, absolutely horrible. I cannot watch and streaming video, my slingbox app, any TV whatsoever unless I am connected to wi-fi. Absolute crap (I am currently using my ATT Galaxy S3)
I have done my research, it seems the international version does not support 4g at all and that the ATT/T-Mobile specific phones, if unlocked, do not have the specific frequency of 2.5.
So, does anyone know of a specific S4 that does work with their network?
Here is a link to their site with the info I am talking about.
http://www.tim.com.br/rj/atendimento/perguntas-frequentes/cobertura-e-roaming/4g
its in Portuguese so I did a translation on the specific question/answer specifying what I am talking about.
5. Do I need to change the device to use 4G?
You need to know if your device is compatible with the 4G technology in Brazil, which is currently operated at the frequency 2.5 GHz. See our website to check the devices prepared to use the 4G connection.
Of course, their website does not have a list of devices! I called them, they had no clue to what I meant.
So, can anyone shed any light on this for me?
Anyone????
thanks.

Reasearch into the LG G4 US991 Model

So i saw the G4 went down to 299 on Amazon.com and decided to buy it for my parents.
http://www.amazon.com/LG-G4-Unlocked-Leather-Warranty/dp/B01774WPQ8
After purchasing and it was too late to cancel, I noticed a lot of people complaining they were having sporadic issues with the US991 model.
This model was manufactured by LG for US Cellular. They are a CDMA based USA Cellular Provider.
When I Googled the mode, I found a page for this specific model directly on LG's website.
http://www.lg.com/us/cell-phones/lg-US991-Genuine-Leather-Black-g4
Specifications
Type Smart Phone
Form Factor Bar
OS Android™ 5.1 (Lollipop)
Technology GSM, CDMA, WCDMA, LTE*
Processor Qualcomm® Snapdragon™ 808 with (integrated) 1.8 GHz 64-bit Hexa-Core CPU
RAM 3 GB
Network Hepta Band/Dual Mode*
Frequencies LTE Bands 2/4/5/12/13/17/25, CDMA 800, 1900 MHz, WCDMA 850, 900, 1900, 2100 MHz, GSM 850/900/1800/1900 MHz*
From what I can tell, WCDMA is just another name for UMTS which is the basis for HSPA/HSPA+ Which means that this phone should be compatible with jut about any GSM carrier providing H+ 3.5g data services as well as typical Voice and Messaging services. What this should mean overall, is this will work as an unlocked international GSM compatible phone.
Data Transmission EVDO, EVDO Rev.A, 1xRTT, LTE*
Dimensions 5.86" (H) x 3.00" (W) x 0.38" (D)
Weight 5.46 oz
Display 5.5" (2560 x 1440) with 538 ppi and 500 nit
Touch Screen Yes
Battery Capacity 3,000 mAh
Talk Time Up to 18.5 hours**
Total Internal Memory 32 GB (21.9 GB usable)
microSD™ Memory Slot Supports card up to 2 TB***
Also, based on US Cellular's unlocking policy page for unlocked carrier locked phones,
http://www.uscellular.com/site/legal/mobile-wireless-device-unlocking.html
The US991 G4 comes carrier unlocked from US Cellular so if there are OS updates and such there shouldn't be any cases of carrier relocking (YMMV).
All in all if you are purchasing it just for general cellphone purposes it seems fine. Rooting and ROMing is another issue entirely.
If anyone can add some additional information to this I would be glad.
I hope this helps someone out there.
We're using one on T-Mobile, and everything is working just fine...no issues so far.
buydig had it for $290 on its eBay store (it went up now) with both black and red leather backs.
LTE bands are OK for AT&T (2,4,12,17) and T-Mobile (2,4,12) in the US.
It's missing LTE bands 1,3,7 which are used in Europe.
WCDMA doesn't have the 1700/2100 band that T-Mobile was using but has refarmed to 1900 in most areas now.
My friend bought the same buydig/ebay deal as above, is using it on Verizon. He just popped his sim out of his dead razr m and it works ok, except it being an unregistered device. His is listed as US99110A for software version, Kernel 3.10.40. It won't do a software update with the sim in (obviously) nor without the sim in it. I guess flashing the US Cellular KDZ over would work, but then it includes all their bloat and there's no way to get back to it's current unbranded status. Would be awesome if it could be updated.

Hi, I just received mine, also using on T-Mobile. Works fine, but a couple issues, and possibly a deal breaker:
(1) After upgrading to Marshmallow and signing onto Google to synchonize apps, LG Backup no longer works. Icon still there, but no response when clicked.
(2) Upgrading, from G3, happy to report that Facebook app no longer crashes with Acore error -- not sure if that's because (a) settings changed, (b) upgraded from G3 to G4, or (c) Marshmallow cured it
(3) Cannot find wifi calling, which is necessary for using free text on GoGoInflight-equipped airliners.
I like the $275 price, but #3 may be a deal breaker. If can't make it work within budget, must choose between NEW G4 without wifi-calling, or used G4 with it.
Any thoughts or suggestions appreciated!

I don't think wifi calling is available as-is with US991 on T-Mobile, but you may be able to use an app for it. Check out "Hangouts Dialer - Call Phones" app.
can any of you guys confirm whether 3g on T-mobile works? I can see that 2g and 4g LTE are fine, just not sure about 3g since my provider has 3g crossed out for this phone.
StraightTalk won't activate it on one of their Verizon SIMs even though it will work on Verizon. I sent mine back and bought a used Verizon model.

So, if you are in an area that T-Mobile refarmed their 3G from the 1700/2100 band to the 1900 band, then you should get 3G. My understanding is that they have done so in most if not all areas.
Just to confirm, will the US991 will get 4g on both verizon and gsm carriers? I have to switch my vzw sim back to a micro sim before I can try. I'm also going to switch to an mvno in a couple of months, just want to make sure it'll work.

Of course, as far as the phone supports the LTE band the GSM carrier work with and the phone is set to Global.
It supports LTE Band 2/4/5/12/13/17/25. I'm using it on GSM carriers with LTE band 2 and 4.

Hi. I'm wondering if I can get some help with this device. I purchased this device unlocked from my local Rent a Center in New York. Since its unlocked, I am using with my servicer provider Metropcs. Here's where im having some issues. Metropcs offers WiFi Calling on all their devices [ have a LG K7 ] as does T-mobile since they own metro. I noticed that the feature is MIA on my G4. I did some research and found out from LG that the phone itself was originally a US Cellular device. I then called US Celluar. I spoke with their techs and was informed that they don't offer WiFi calling at all with their service, but it doesnt mean the phone doesnt support it. Believe it or not, the tech told me that its more or less a software thing. I went through the stage to upgrade the device to Marshmallow, but apparently its not available. I noticed that all US Cellular LG G4's have Marshmallow. Im wondering if theres a root method that might fix my issues. I looked around and didnt see one for this LG G4 US99111a. I only see them for US99110. Can anyone here at XDA possibly help? Any and all info will be appreciated. Thanks in advance.

There is not root method yet. Since wifi calling is a metropcs/t-mobile feature you can't get it in a device is not from them, unless someone port a metropcs/t-mobile ROM to other carrier devices.

I kinda figured this was the case, but was hoping. Im wondering though that if and when US Cellular does support WiFi Calling, will an update from LG activate the feature. Either way, its a great phone. No complaints. Just wondering what marshmallow is like on it.
Not sure if the wifi calling feature from one carrier works in any other carrier.
Sent from my LGUS991 using XDA-Developers mobile app
It does with other phones I have had. I owned an Iphone 6 Plus from Verizon. The phone is factory unlocked, and I used it on Tmobile/ATT/Sprint before moving to metro. Verizon initially didnt offer Wifi calling. The feature was active in the phone once I left verizon for the others. So its possible. Hence my confusion as to why its not active with the G4, and why I believe the tech at US Cellular told me that its more or less a software issue.
Iphone is kind of different. But I hope it works with Android

Does our Axon 7 support AMR-WB (HD Voice)?

Does our Axon 7 support AMR-WB (HD Voice)? I know it supports VoLTE but what about AMR-WB?
Here is some definitions for who does not know what that is: https://en.m.wikipedia.org/wiki/Adaptive_Multi-Rate_Wideband
Did not see any discussions on this, let me know your thoughts.
I can say that when I talk to another T-Mobile customer when on LTE the call has got to be in HD because I can tell a big difference. I did not reference your link in the wiki so I am unaware if there is different types of HD calling. Maybe this helps you some!
VoLTE is a connectivity standard with a broadcast method. AMR-WB is a codec. They can exist exclusively, not depending on each other, especially since AMR-WB scales itself through a range of data rates.
Both are reportedly supported on this device. Whether it is actually used depends on the way the network you are on handles it.

Yeah, that would be VoLTE or Voice over LTE.
AMR-WB is a HD codec over the 3G network not LTE . My network does not support VoLTE, so AMR-WB would be the next best thing. There are many devices supporting the codec. For example I had previously HTC M8 and the quality if the other phone supported it (Note 4) was very good, thus meaning that AMR-WB was in play as the M8 did not support VoLTE. So the network supports AMR-WB, Axon should support it also...
