Exactly. This argument does make sense only for yanks and does not hold any water outside of US.

World is much bigger than US and there are a lot of other LTE networks than ATT/VZW/Sprint where el goog does not need any carrier endorsement or subsidy deals. Since N4 is an GSM/UMTS phone, the CDMA carriers are irrelevant anyway.

That same OptimusG is sold around the world as an LTE phone. Freely, without any subsidies and contracts. LTE does not prevent it.

Somehow I doubt it, why should those costs go up? It is not like LTE brings anything new to "support". For a ordinary user it is completely transparent. It is either available and "works" or not. And if not, then it is something to solve between customer and carrier, LG/Google would simply refuse to deal with carrier network coverage problems and just redirect to the carriers.

By the way, what is the big deal in the USA with that "support" anyway? I mean, how it is different from fridge, pocket calculator, TV or tee kettle?

Yes. And this is not childish at all, this is big and serious fight to death.
[Nexus 4 General] kaiser_tytnii:
set the right APN too...

for instance, Rogers APN is ltemobile.apn
[Nexus 4 General] zim2dive:
according to GSM arena, there are 3 models of the Optimus G. http://www.gsmarena.com/results.php3?sQuickSearch=yes&sName=optimus+g

I can't find a definitive reference, but I thought it was at least very difficult to build a "universal" LTE phone (so many antennae, etc.. and I can certainly understand if Google didn't want to produce multiple flavors of the N4. (Apple has 3 models of the iPhone5)
[Nexus 4 General] kanetheninja:
Well, as much as I might want to, i'm not sure google is ready to write off the US market just yet in there quest, but i see your point.

I was thinking more of the company to company support issues.

Warning: This is me speculating and might be hard to explain clearly

For a lot of these types of things, the MFG to MFG contracts can get complicated and pricey. For example, I work with a phone system ( a PBX ) that has VOIP capabilities built in, they are there ready to go. To get them to work, we have to buy a special key code. They do this because of possible increase support calls from us to them, even though the customer never knows or may care about the voip system. They also do it to you know, make more money. You see similar things with the way windows is built and all over really.

The other issue is that even though the CHIP exists, it's not QAed or probably tested, nor do they care if the testing fails.

For example, I believe that various chip MFGs have done similar things in this regard when making lower clocked version of a chip, they simply have more lax QA or will bump chips that fail at a certain MHZ to the lower version where it will never see issues (this is one of the reasons overclocking can be hit and miss)

Anyway, my point is just there are a ton of reasons why they might not include a LTE radio outside of just LG forcing them to do it for market segmentation purposes.

Or it might just be for market segmentation...
[Nexus 4 General] zivan56:
Best to go to google maps settings->about page and look for "myl:.."

That will tell you the MCC:MNC:LAC:CID

For CDMA, Google overloads it to include BID, NID, SID....for LTE I have no idea exactly what it does, as Android 4.2 is the first Android OS with properly LTE cellid/signal info without using manufacturer specific APIs. Hopefully they updated Google Maps to support it.

On older phones with LTE, it will return the fallback networks info as if LTE doesn't even exist. So it will be the CDMA/UMTS cellid.

Even if they got that right, they also have to map the LTE networks in their database for it to work properly.
[Nexus 4 General] draugaz:
2 of them seem to be rather special carrier versions.

They don't need to since VZW/Sprint and other CDMA providers drop out of context anyway. The rest of the world seems to be covered by just one iphone5 model using LTE band 3 which providers around the world are increasingly refarming from GSM1800.

So it may not be a perfect LTE device for each and every LTE network in the world, but with 2-3 most common LTE bands it could cover the most of the world.
[Nexus 4 General] Matt1408:
Pretty detailed. I like it!

So this basically means is that there is no fall back to the UMTS location as in previous versions of JB. Makes sense why it works on my One X (running CM10) and doesn't on my N4 (running stock 4.2)

I still don't get why people say Google Now works then, since it relies on location services which are unavailable.

LTE is working, it's the location services attached with LTE that are not working.
[Nexus 4 General] draugaz:
It is not like it would mean writting the US market off. N4 with some most popular LTE bands would not be any worse than it is now, even if those bands don't work for US carriers.

Especially when there are 2 or 3 LTE bands which seem to be turning to "universal" worldwide bands.

On the other hand, US mobile handset market is a very special animal. I think the N4 has much better chances for success outside of the US, where consumers are used to buy their phones in a "normal" retail (all providers and all phones in one place) or online and not so drilled on those "magical" 100-200$ price points.
[Nexus 4 General] kentt1:
What exactly do you mean when you say Google Now is not working. I've been using LTE on Rogers and haven't noticed any problem yet. I'd be happy to do some debugging on my end.
[Nexus 4 General] kanetheninja:
Speaking of, isn't LTE more or less a US thing at this point? I know there are some in Europe but they are even less widespread that ATTs right?
[Nexus 4 General] comminus:
I wouldn't call it a US thing. http://en.wikipedia.org/wiki/List_of_LTE_networks
[Nexus 4 General] kanetheninja:
I didn't mean to suggest that there are no LTE networks outside the us, only that the overseas LTE coverage is even more spotty and fledgling than in the US.
[Nexus 4 General] ghettopops:
There is a member over in Q&A that seems to be connecting to band 13 with AT&T. Any confirmation?
[Nexus 4 General] Matt1408:
Google Now doesn't work because it can't find my location. Starting it will have a loading circle. Eventually it will give up and use your last known location. The bottom of the app would display Refreshed 6 hours ago.

To debug:

Go to your *#*#INFO#*#* as if you were going to enable LTE. In that menu you should see a list of information.

There should be a line that says Location: LAC =

Does that say unknown for you?

Also it should give you a bunch of neighbouring towers. Both have no information for me.
[Nexus 4 General] cmstlist:
"LTE:13" does not mean band 13 AFAIK. The phone does not have hardware for band 13.

But it could well mean that poster lives in an area where AWS LTE is deployed on AT&T.

My guess is the first Band IV deployments will be where AT&T doesn't own any 700. They do own 700 in Seattle so no AWS deployed.
[Nexus 4 General] draugaz:
Yes, LTE coverage in the US is better than in most other parts of the world, but it is rapidly changing.

So, LTE is also relevant outside of the US, even if it is not fully available today, in a half of the year it might be.

And since you pay a full price, you typically expect a phone to remain relevant for much longer than a typical US consumer, typically there is no "contract renewal" thing where you are kind of forced to upgrade.

Preferred network: LTE/GSM auto (PRL)

It's funny, because my LAC also says unknown as soon as I switch from WCDMA preferred.

Indeed I also have "Neighboring CID: no neighboring cells".

However, I haven't had any problems navigating. I've used the turn by turn navigation without issue a couple times now. Google now loads quickly.

Let me know if there is anything else I can help with.

EDIT:

Actually I have to take that back now. I tried clearing my AGPS and turning off WiFi and I could not get a proper location. Not sure what's going on because I have had luck staying on 4G and using turn by turn. Not sure what else to say because I really don't know much about this sort of thing. Hope that helps.
[Nexus 4 General] kentt1:
Okay this is the ultimate test:

I did a factory reset

Turned off wifi and turned on LTE/GSM

There was no way for me to get a GPS lock.
[Nexus 4 General] peachpuff:
I noticed a couple of my calls went straight to voicemail when having lte enabled, am i the only one?
[Nexus 4 General] Kermee:
What did you set your 'Preferred Network:' to? If you set it to 'LTE Only', it won't drop back to GSM for voice calls since there's no VoLTE yet on any LTE-enabled North American carriers.

[Nexus 4 General] rbozzo09:
everything works fine

Hey I hope im not late to the party. Just got my nexus 4 today. Just went into the phone settings and changed the CDMA only to LTE/GSM/CDMA auto, then i went into the apn settings and just added the extra apn of lteinternet.apn and selected it.

I can make and receive calls and texts. I get gps lock in under 3s EVERY TIME. I'm not on wifi either. and the 4g status comes up...it also cycles down to 3g when im not doing anything.

I will report back in a few days if anything goes awry but i can expect my battery life to suck no?
[Nexus 4 General] peachpuff:
Its set to lte/gsm auto, it seems to stay on lte majority of the time though, rarely switches back to 2g/3g.

LTE tethering

I too had problems trying to tether, but I followed these instructions from super_paws and am able to get LTE tethering going. It worked for me on Rogers LTE.

[Nexus 4 General] THE_KINGDOM:
It is GPS data that is affected! not the satellite reception. Therefore for the only way to test if your GPS is affected, it's by turning LTE on indoors (with no satellite reception) and trying to gain a lock (make sure WiFi is off)

[Nexus 4 General] Dave778:
Thanks bro! This works great after the factory reset & every boot after it... as long as I dont touch the APN settings.

The problem I'm having is that my Fido LTE APN disappears after the factory reset.

So when I add an LTE APN back the settings, then network mode settings stop sticking after reboot.

Any help would be appreciated, thanks

[Nexus 4 General] kaiser_tytnii:
i second that, the only way i think would make it work is to manipulate the default APN setting AND build.prop in the .zip file before you flash the ROM... will spend some time to dig into that later on

Too bad they sold out today and i only got the email heads up 30 minutes before they went on sale.

I gmail sync was messing up on my s2x so i never got the notice in time :(
[Nexus 4 General] Dave778:
Would it be possible just by editing the build.prop files in the flashable zip ? The way I see it is as soon as u edit the APN settings on the rom it loses the sticky at boot LTE & jumps back to WCDMA P.

I'm am getting between 30-60 Mbps with Fido.

Has anyone figured out how to make Google Now & GPS work properly on LTE?
[Nexus 4 General] kcuartero:
anyone on koodo able to connect?
[Nexus 4 General] torontobc:
One can arguably say that over 90% of people don't use 5GB on a phone. When you add the tax and shipping to 16GB it's over $440 - not worth it. Why not pick a unit locally and only the 8GB if it becomes available. A full fledged computer can be bought for $300 now. I don't understand the price gouging on these little units. But anyhow, I will wait.... :)

If you search for some of these files, you will find references to other phones out there.

I guess for a test, someone can try to get the Optimus G files and replace the above. The files are signed per file, so as long as its a valid file it should work. Use standard fastboot flash radio ...

Obviously, major caution, you may brick your phone. Just a theory on how to perhaps unlock more LTE bands if its possible with the hardware.
[Nexus 4 General] cmstlist:
I don't explicitly download large files to my Galaxy Nexus but I always end up around 6 out of 16 GB free on average. I would be going insane with cleanup if I had 8 less. If you don't think you could ever possibly fill up 5GB, perhaps you are just not familiar enough with the device.

I am on Rogers optimus g now and will see what I can do here... got no nexus 4 on hand though... selling the 8 for the 16 tomorrow...
[Nexus 4 General] TheManii:
The safest way would be to flash amss.mbn/NON_HLOS.bin to the baseband partition. Then you would be able to skip the whole "flash everything and potentially brick the system by hosing the bootloaders."

I've seen people flash garbage data to baseband, and i believe they were able to recover as long as the garbage didnt overflow into other partitions (on a 1st gen snapdragon, i can only hope it applies to S4's)

Unfortunately, there's no direct file that corresponds to amss.mbn/HON_HLOS.bin in there, it's obviously one/several of the files that make up the actual baseband(s) though.
[Nexus 4 General] zivan56:
Nice, although I have no idea where you would get it from. It is either in a memory block somewhere or on the filesystem. It's most likely a memory block somewhere.

That is what I mentioned, replacing individual files and not just flashing a random whole image. I'm sure the Nexus would gladly accept any FAT16 filesystem image that fits into the partition (hopefully it will do a partition size check berforehand!)

It basically looks like 1 image containing both the AMSS and modem...along with the wcnss (i.e. wifi/bluetooth/etc) and a few more SoC drivers.

So far, comparing file sizes/names, I can see the dsps* (not dspX.bin where X = number) files are called modem* on an HTC One X (AT&T version, with Snapdragon S4) with a similar header/size per file.

Likewise, it also has the q6* files.

The modem* and q6* files are found in radio.bin (modem*) and adsp.img (q6*) on there. So they appear to be AMSS.bin/modem.bin equivalent images.

The One X has all these above files I listed split into adsp.img, rpm.img, sbl*.img, tz.img, radio.img, and wcnss.img. So I am quite sure it is just all bunched into one file for the Nexus 4.

So a start would be to take those files from a Optimus G and try flashing the file. I believe the sbl* files are the core bootloader files, so doing that wont touch them.

P.S. only used One X as a reference due to splitting up the SoC firmware into multiple logical files, not saying anybody should flash those...it just points to dsps* and q6* files being the baseband modem core files IMO.

I could be wrong but I thought there was no actual physical LTE receivers to receive other bands attached to the hardware according to ifixit?
