I've had a Sprint Galaxy Nexus for about 4 months and have never seen a 4G indication. It's non-rooted, running stock Jellybean with FH05 radios.
I live in Houston and have also traveled to Chicago, Phoenix, San Francisco, and Los Angeles with this phone without ever seeing a 4G indication. I looked at the Sensorly 4G maps in Houston and drove along the 4G routes for a couple hours and never got any 4G signal.
I've played around with the *#*#4636#*#* menu but I haven't found anything that made any difference. Most of the posts say to select "LTE Only", but my menu does not have that option. It is currently set to "GSM/CDMA Auto (PRL)".
Can anyone think of something I'm missing? I'm eligible for an upgrade next month but I was planning to stick with the GNex a few more months. This 3g-only crap is killing me. I was hoping to keep the phone stock so I can pass the phone off to my mom/wife when I upgrade (without having to revert to stock), but it looks like I might have to root/rom it if I can't find a better answer.
crying for help :crying:
I would say after typing in the secret menu code, turn off the radio and turn it back on; see if that does anything.
Are you sure their isn't a LTE Only option? It should be at the bottom like the last option.'
If you're really that desperate for LTE, you might have to root your phone and flash a radio (which isn't too horribly hard to do) or change the PRL manually.

I've tried turning the radio off/on. I don't see an LTE Only option in the menu, but I'll check again to make sure.
I'm beginning to think that I may need to root/flash to get it going. I was hoping that having one of the nexus phones would get me away from flashing half-working ROM's every couple weeks, but it looks like I'm headed back that way :silly:.
Thanks for the suggestions
4G works just fine stock. If it isn't working for you now it most likely still won't work if you root and flash a different ROM. 4G maps aren't all that accurate and 4G signals drop in level fast when there are things between you and the tower. Either something is wrong with your phone or you just haven't been in an area which a strong enough 4G signal for your phone to pick it up. Make sure your phone is set to CDMA/LTE in the mobile network settings and not to CDMA only.

How do you know your area has LTE? Do you know someone who has your carrier that gets LTE? If you're going by a coverage map, as said before, blah. You shouldn't need to tamper with your phone to get LTE. Try contacting your provider if your that concerned. The setting you have in the secret menu does a lot. Make sure that its set to something that allows LTE. Even my GSM HSPA+ nexus has an LTE Only option.

Thing with sprint ive noticed is it uses whatever signal is the strongest. So while you may have 4g coverage, if your 3g is even a signal signal strength higher, it always uses that. You should be able to force lte, but from what I've read that causes calls and SMS/MMS to break until you revert back to auto.

I had the same suspicion about the coverage maps which is why it took so long for me to post for help. Recently I sat in the same car with an EVO LTE that was getting a 4g signal and I got no 4G. That's what made me take a second look at my settings to see why I wasn't getting it.
It could very easily be a matter of picking the strongest signal and I'm ok with that. The secondary problem that I have is that I've read so many descriptions of an "LTE Only" option in the networks menu and I don't have that either . In fact, none of the options in my menu specify "LTE", even in combination with CDMA.
My list of networks in the special menu:
WCDMA preferred
GSM only
WCDMA only
GSM auto (PRL)
CDMA auto (PRL) (3G)
EvDo only
GSM/CDMA auto (PRL) (default - 3G)
Unknown
Thanks for all of the responses, I'll keep digging for a solution.

I was just wondering what network settings Sprint users are you for the best signal?? What I mean is what preferred network type are you using. I have noticed since I roam at home mine is mostly on unknown but a fresh boot up of stock starts on GSM/cdma auto prl. But I get the best signal when I change it to cdma auto prl. On GSM/cdma auto prl I'm roaming but I don't get any bars and data connection turns on and off but cdma auto prl I get at least one bar in and out but data stays connected and all my texts and calls come straight through. On any other setting its no telling when I'll receive a notification could be hours or days long as I'm home. But I have noticed that having it on cdma auto prl I get slower speeds like it picks evdo rev: 0:7 and fluctuates between that rev A and 1x. There is another setting in a different menu I can't really remember what it's called I forgot the dialer code to get to the menu I think it's like ehrpd or something like that. Any help or opinions greatly appreciated I think there are settings that are making this phone so slow on data my Photon is a lot faster on 3g than my nexus but Motorola will lie about your signal unless you know better but its always got a stronger signal and faster connection. One more question does a kernel have anything to do with good or bad signals I see my phone acts different with different kernels like stronger signal faster connection and vice versa.
Thank you

I'm running stock ICS on a VZW Galaxy Nexus. Is there any way to keep 4G/LTE enabled but turn off 3G?
I ask because I often tether my computer at work, but there is a weak LTE signal at my workplace, and a strong 3G signal (they may even have VZW 3G repeaters in the building) and I always end up getting 3G speeds. I've tried a few app from the market "LTE onoff", "3g/4g on/off" and some others but none seem to have an LTE only option. I haven't rooted my phone yet, but would be open to rooting if there is a root only option for this. Would be awesome if someone could help!
There's app called switch pro widgets ($1) and it didn't allow you to toggle the 4g and anything else you want to adjust.

no. the 3g signal is your voice service.
*#*#4636#*#*
Then phone info > LTE Only.
Do note LTE is data only, no voice.
Beamed from my Maguro.
How's it going everyone. Just left sprint for T-Mobile. Even with the problems I'm having its still better than sprint crappy network. Anyways. For some reason no matter what ROM I'm on I'm having issues where the WiFi will turn off it will go to 4g than WiFi will randomly turn back on. Or I'll have great service than randomly I'll see an E near my signal bars and it slows down for a good 5 minutes. Any idea what may be causing the problem?

Well if you are getting the E, that's Tmobile's network for ya. It is quite spotty. I get the same thing and goes back to 4G soon after. One of my main gripes with Tmobile.
If you do what DocHoliday said, it won't work at all. Just won't have any signal at all. If you leave it to auto, you will at least get the EDGE network.
Did this do the same thing with your old phone? If not, not sure what the deal would be besides weak radio maybe.
Try using the Llama app to force wifi on and disable the radios when around specific locations?
That's a workaround though...

Its worth a shot. I had issues with staying on 4G when I first got the phone. That fixed it for me.
Spotty service depends upon your area imo. Sounds more like a network issue to me. Could be a side effect from all the refarming work they're doing on the network. Its a nationwide project so it can hapoen anywhere.
@op
If you turn off WiFi does it work as it should? If so check that WiFi calling isn't enabled and set to WiFi preferred. If it is turn it off and test, then if fixed turn it back on and try Cellular preferred.

For what it's worth, I had this issue yesterday out of the blue. Nearly every time I would unlock my phone, wifi would be disconnected and I'd see the 4G icon. After unlocking the phone, a few seconds later it would connect up to wifi again. And yes, this is even with wifi set to always on in the advanced settings.
I realize there could be multiple causes for this symptom, but the fix for me was simply forget the wifi network and connect up to it again and the issue disappeared since then. Hasn't happened today yet either.
I live in area that does not have 4 g so it stays off, however today at airport I tried and no 4G toggle anywhere! Where did it go, I swore when I got s3 I tested 4G but now it's gone? Thanks for help.

GS3 doent have a 4g "toggle" as you say...but you can make sure its enabled
settings-->more settings-->Mobile Network-->Network mode.
Preferred network mode should be set to "CDMA/LTE/EVDO"
If you have "CDMA/LTE/EVDO" enabled, anytime your in a Sprint LTE area your phone icon will switch from 3g to 4g.

it shouldnt chew up ure bttery at all, as all it does is search the network for 4gLTE and if it doesnt find it, it will automaticly go to sleep and try again like 2 or 3 hours later or periodically as it tells u. .however u do need to have sprint automatic connention left on in order for that work. atleast thats what i got from reading the sprint connection optimizer information it gave me.

The optimizer isn't for the LTE. I hate that garbage so I always leave it off. As long as your preferred network is set as stated above, it will automatically switch between them. Side note though, it may switch back to 3g if you don't have a very strong 4 g signal. It likes to be weird.

Do any of the custom ROMS have a toggle for 4g/3g? I live in a 4g area but sometimes the signal isn't strong enough so it goes to 3g. Quite annoying. It would be great to toggle 3g off and force 4g.
So I had s2 before s3, so I assume the s2 was a 4 -g wimax? It had a toggle widget.

Have you tried updating to the new radio? I believe they boosted the power to give slightly better LTE connectivity in those kinds of environments.
There is a way to force LTE on the GS3. I did it with mine so that I could map out the LTE zones with sensorly a bit easier while I was driving over the weekend. The way I was able to do this is you need to have Nova Launcher downloaded and installed.
Once you do this, long press on the home screen and go to "Shortcuts".
Next click on "Activities"
Next scroll down to "IOTHiddenMenu"
Then scroll down and click on "IOTHiddenMenu : HDR1X_Selection"
Doing this will allow you to force LTE only mode. Keep in mind you WILL NOT be able to make any phone calls while doing this. For some reason the GS3 requires the phone to be in LTE + CDMA + EVDO Mode to make calls even if you have a very strong LTE signal.
Another app I would recommend downloading is called OpenSignalMaps. Once you have the LTE only mode turned on or even the normal LTE + CDMA mode, you can use this app to refresh your network by clicking the little refresh button at the bottom left of the app in the Overview tab. What this does is pretty much turn your phones mobile networks on and off and then scan for LTE first before scanning for EVDO. I have been able to connect to many more LTE sites by doing this. Even ones that are fairly far away.
Hope this all helps. Let me know if you have any extra questions.

Thanks. Unfortunately, the "Network" app would not run. So I followed a similar line, and found "3G Reconnect". It does not fix the connection issue. Any other thoughts?
I finally got LTE locked on with Telus other users confirmed Rogers, AT&T and Bell(thanks) . No service disconnections, even while on wifi.
The problem I see is conflicting settings while flashing roms/modems. This seems to be the only fix. I'm pretty stoked I figured this out because I was about to switch back to my s2x out of frustration.
This took a lot of trial and error, literally had nothing to go on and no where in particular to start. Enjoy.
MAKE SURE YOU ENABLE LTE TOGGLE IN ROM AND HAVE IT ON BEFORE STARTING.
1. Network mode(settings/wireless & networks, more/ mobile networks/ network mode) set to gsm/lte/wcdma
2.Phone setting in test mode *#*#4636#*#* set to lte/gsm
at&t / rogers should select gsm/lte/cdma in test mode
3.Recovery flash latest modem mumLL1
(at&t users flash ucdlk3)
Wipe cache/dalvik
4 . Reset. Give it a couple mins to ask the network for lte.
If you disable Lte(through toggle) and want to use 3g/H+ for battery saving, the only way I've been able to reconnect to it; is to re enable(toggle) and reset, wait a couple mins to connect.
Side note: depending on your 4g service area, it may bounce around 3g/H+ which is normal.
When you place a call it will drop to 3g (the believed reason for this is that the phone knows you won't need heavy data so falls back to ease up on the battery during calls) but will reconnect a couple mins later. Our phones are slow to negotiate Lte connections with the radio testing sockets and network stability before committing, so be patient.
Let me know if this works for you and which network. Thanks.
