Reasearch into the LG G4 US991 Model

[veer01_42]

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.

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.

G4 US991 on T-Mobile

We're using one on T-Mobile, and everything is working just fine...no issues so far.

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.

 

[okayokayokay]

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.

I previously wrote

WCDMA doesn't have the 1700/2100 band that T-Mobile was using but has refarmed to 1900 in most areas now.

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.

It should work on Verizon LTE since it has all 3 LTE bands verizon uses.

Thanks! Would you happen to know about GSM compatibility? I'd like to keep my options open when my contract with big red ends

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.

Just bought a new G4 on eBay with extra battery, battery charger cradle, and extra leather cover for $289 shipped. Brand new. Box says manufacture month was 03/16. Its working great so far. Its on MM out of the box. Threw an Unlimited T-Mobile SIM in it and its working pretty good. Nice.

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.

 

[dennis5pia]

Not sure if the wifi calling feature from one carrier works in any other carrier.

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.

 

[dennis5pia]

Iphone is kind of different. But I hope it works with Android
