[Q] Roam only?

Alright so Roam Control does not work on my galaxy nexus for sprint. When I'm at my friends house, I literally show no bars and it still won't auto roam. Is there any way to force it into roam like I could on my evo 3D via roam control?

This may be a long shot but have you rebooted? I think I've answered the "Force roam" question before and a simple reboot was the culprit.
Secondly, are you rooted? it's a requirement.

Yes I'm rooted. I'll try doing it and then a reboot
Does not work.

I second
Roam Control 2.2 does not work with the Galaxy Nexus. A huge blow, and now I am considering going back to my Nexus S more than ever.... Any updates on this, or is it even being worked on? My 14 day window is closing fast... Thanks

Agreed.. i have the old old version working on my cm9 gs2.. make sure you have data roaming enabled and phone isnt set to home only.. also if its th data toggle your data off and back on after settin roam only in roam control

That's a real bummer, seeing that RC won't work w/ Sprint GN. RC is a lifesaver at times.
Any other solutions for rooted phones?

Have you guys tried this http://forum.xda-developers.com/showthread.php?t=1660740
Works like a charm for me. Update PRL to get back on Sprint.

Where did my 4G go!

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.

doesn't it chew up more battery?

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.

Sounds like your thinking of a wimax phone. I I had a Motorola Photon and you had to physically turn 4g on and off on it.... I think most wimax 4g phones are that way.
Sent from my SPH-L710 using xda app-developers app

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.

No data connection at all
I have the settings on GSM/HSPA/LTE, but lost data connection completely. Tried to restart and turned on/off flight mode - still no data. Voice in and out is OK. I finally managed to reconnect by repeating the process. Is there a better way to reconnect?
Thanks.

Check out "Network"

with the latest l13 radio my phone will not stay on 4g it is heavily biased to 3g and I do not know how to fix it. I am right next to the 4g towers.. ... any thoughts? Thanks

Thanks
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?

Wifi randomly tuns back on....

Not sure if im missing a setting somewhere but my WiFi toggles itself back on randomly after i turn it off. I checked all the wifi settings under ADVANCED and everything looks like its in the correct setting...
Network Notification / unchecked
Keep WiFi on during sleep / (Tried both ALWAYS and NEVER)
Check for internet service / Unchecked
WiFi Timer / OFF
I am using Blazer ROM since I got the phone. Anyone having the same problem? It would be no big deal if the wifi radio didn't consume as much battery.

Not sure if Blazer rom has the option or not or if it would affect it turning back on, but is the Connections optimizer feature enabled?
Its under More Settings > Mobile networks > Connections optimizer

Sweet, I think that was it. I turned my fonts to 'TINY' and only read about 1/4 of the fine print. If it turns on again, ill just need to go out but buy some sage to rid my house of evil wifi spirits!
Thanks...

if i uncheck connection optimizer will it never looks for even lte?

I'm guessing "preferred network mode" will select the LTE preference or not. Connections optimizer only refers to WiFi in the help text.

I'm pretty sure hausman is right on that, but I'll try it out later today when I go into an lte area and report back with my findings.

After a bit of testing in different 4g spots I can say that the optimizer does not effect 4g at all. And it does indeed only refer to the wifi.

Ive had a similar issue and im not sure why either!

Same here on stock rom.. even before I rooted

Connections optimizer was rolled out to "ensure phones haves the best possible connection without affecting battery life" On older WiMax phones it also does affect 4G. It uses location data and saved WiFi IDs to know when to connect. Sprint likes it because it offloads data onto wifi/4G whenever possible.

Ah ok good to know. Though I should of probably rephrased my post since it was a reply to gotojanoo to let him know that it does not stop the phone from searching for a lte connection.

Can't connect to the internet after update.

My Galaxy S2 went through an update through Sprint this morning, and ever since then I can't connect to the internet either through wifi or 3g/4g. When I try with wifi, it never acquires and IP address, and the 3g icon doesn't even show at the top anymore even though I've checked to make sure the 3g data box was checked.
Hopefully someone can help me out. I don't want to have to do a factory reset and lose all my data.

Data connection lost

I been having this issue since I loaded up wicked rom on my phone. Works for 5 minutes only then loose connection, the only way seem to get connected again is through making a phone call to any... I just call my voicemail to get connected again so I don't have to annoy people! Help!!!

The current modem seems to *really* want to be on LTE. If you don't care about LTE you can disable it...settings - connections tab - more networks - mobile networks - change "Network Mode" to GSM/WCDMA. You'll still get HSPA+ speeds, but it should stay connected better.

Thanks man, it's just weird that the only way to get back connected is to make a phone call... I was at the time bike store yesterday and they mentioned something about updating the towers to LTE and should be over end of this summer... They said they are already ahead of sprint as in service at the moment and they are trying to be on the same page as AT&T and Verizon. I messed with the option by the way many times but didn't notice the difference yet but I will update the result on a following reply in the future. Thanks again
