That's normal. The band switches because we can't make or receive calls through LTE only.

Well I got tired of the signal strength and flashed the wicked rom 10 and I get alot better service. I really like cm11 but for some reason it doesn't work for me.

I'm looking at some other threads on similar problems, but I'm wondering why my GNexus doesn't go to 2G automatically.
I must manually change it to 2G/Edge every time. All the other folks around me seem to continue without issue and are able to make calls although their signal isn't too hot. GetRIL says baseband and RIL match. I'm using XXLA2 on AT&T in NYC.
Tried searching around for a solution, but I'm not finding anything.
Any help would be appreciated and I hope this hasn't been asked a million times before as I was unable to find a solution. Thanks.
As in it doesn't change from 3g/4g to 2g automatically when there is no 3g/4g signal available?

Right, it just continues to show No Connection or is it Signal...? Anyway, I can't make calls, go online, anything until I switch to 2G. Is that normal? Lol.
Weird... mine switches to E when I'm in a bathroom depositing =]

Ok so I have an unlocked LG Nitro HD with custom ROM (CM10) and it has a very weird problem. I've tried two different AT&T MVNO SIM cards (AirVoice and Consumer Cellular) both have the same issue. My data signal keeps changing from H to H+ and occasionally to 3G like every few seconds regardless of where I am using the phone even outside. I don't understand what the problem is. What could be the issue?

Are you able to use mobile data or are you just wondering why the icons go back and forth?

Data does work but it seems to drain the battery with the networks constantly switching and on occasion I get a "No Connection" screen on certain apps, I guess because if I open an app while its swapping networks the app cant connect. It's strange.

Yeah, constantly swapping networks will drain the battery.. what about your APN settings?

They are set up properly.
I had another odd problem, just a few minutes ago was texting someone and all of a sudden phone froze while vibrating then restarted! Don't know if that's a bug in CM10 or what, maybe the network swapping is as well.

Maybe make a backup of your CM10 and try flashing a different ROM not based on CM10.

I think this is the same issue that I recently fixed in quattrimus. I will try to get the fix included in the cm kernel soon. You might try my Rom to see if the fix works.

I tried installing CM9 and it appears to have fixed the problem, the phone doesn't try to connect to the H+ network anymore, only the H network and seems to stay on it so far. I did see it quickly go over to the 3G network but it doesn't appear to be causing any issues, it went right back to the H network. However, I really wish the CM10 ROM worked right, as CM9 is so old...

CM10 is snappy and oh so buttery smooth, I give you that. On another note, did you try any other CM10 variants? I'd give tdmcode's AOKP a spin. He says he might have fixed that problem you were talking about in his build.

I downloaded the CM10 ROM. It seems to behave slightly differently. It stays on H normally, but when I start to do something with data, it will go to H+ until the data loads, then go back to H. So far no disconnects, I'll keep you posted. Right now I have very limited data, I'm switching to T-Mobile as soon as UPS decides to deliver my SIM card (just found out they have a 1900MHz HSPA+ network in my area!) I'll be able to test it better then, but for now I'm trying to stick to wifi, especially since I wasted so much data tonight playing around with this stuff, lol.

Ditto... H and 3g are subsets of each other. Namely they can handle simultaneous voice and data 4G (h+) and lte can only handle data. So it switches back to H so you can receive and make calls plus it uses less battery. If you are on either 4G techs and receive a phone call while downloading it will automatically switch to H from h+ or lte, this is why. The only way you will never see this is on an AT&T rom where it only has 4G and lte icons.

H+ isn't a subset of 4G is it? I know that the CM's have separate icons for 3G/H, H+, 4G, and LTE.

That certainly is debatable but the US's largest carrier considers it to be, it behaves like 4g, H+ may not be as fast but it is 90%+ as fast in most markets small enough to not make a noticeable difference as far as people's perception and the technology behaves like LTE in a lot of respects, CM is international so it just conforms to International norms so that's why you get H+ AND 4G (LTE) designators.

Hello Everyone,
I use wifi calling at home because t-Mobile's signal is weak. My S3 is currently running Darthstalker version X and is on Baseband t999uvdlc. When receiving or placing calls using wifi calling, the phone just randomly hangs up. It is still in range for excellent wifi signal and I have attempted both 2.4 and 5.0 ghz frequencies - both have the "random hang up" problem. Does anyone know a fix for this? Wifi calling seems to work perfectly on my Galaxy Note II - it is just the S3 that has the problem .
Thanks in advance!

Have you tried it on other ROMs?
Sent from my SGH-T999 using Tapatalk 2
Yes. It seems to happen on all the ROMS I tried. I think it was also happening on stock but can't remember.
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.

Re: Fixed service droping and locked LTE
To check if it worked. Go into test mode and it should say Lte in network type.

So does this mean we get no 3g?
Sent from my Mind using Telekinesis!
Yes everything works. I can unselect lte in my toggles and it drops to 3g/hspa. When I re-enabled lte I noticed that I have to make sure in network settings lte/gsm/wdcma is selected and reset phone.

O wow lucky u I can't unselect on Att lol
Sent from my Mind using Telekinesis!
Which rom are you on? Should be up in your toggles. Basically it changes you network settings from cdma/gsm to lte/gsm/cdma. But it conflicts sometimes.

Its there it just doesn't do anything because all the modems on the Att S3 are Rill locked or something so we don't have the option to do it so easily

Ok sounds promising but unable to get my ATT phone running ROM cyanogenmod10.1 03/04 nightly into Test Mode using the keypad code provided. This does work for stock ROM phones. Do you know any other way to get into the test mode?

Yeah I'm pretty sure everyone is using cm10 or aokp. Not sure if stock is having these problems. If they were I'd be on the phone yelling at Telus.
Xda I747
So let me get this right. This fixes the signal jumping around on cm10/aokp ROMs?? That's the only reason I stay on a stock based rom. I'm tired of seeing my signal jump back and fourth from 4g to 3g etc. On stock I always have a rock solid signal. It does not jump around..... Thanks in advance...
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
Yes for me and others didn't even get 4g, also it would completely go out of service. Now I get steady 4g.

Sorry man, I tried looking around for a way. Could be the rom you're on. I know Liquid and Carbon are fine. Probably a couple more that I don't even know of, others have success with.

Hi all,
I've been searching this morning on here for issues around Cyanogenmod and LTE, and I've tried following some ideas and help on here, but I'm struggling to get a solution. Cyanogenmod updated itself this morning to CM11. I updated GAPPS and everything is running ok. The issue is that I no longer get LTE connection. I am in an LTE area, on an LTE provider (o2 in the UK).
I deleted my APN's and got O2 to resend the info, and it all looks like it should look (I think) but there's still no LTE.
Is this just an issue with CM11, or is there something more than I can do? Do I need to roll back to CM10 to get LTE? I've read there might be bluetooth issues too.
A lot of whats in this thread seems to be for "Rogers" network in the US, so I'm a bit nervous of doing anything that might screw the phone up anymore than necessary....
http://forum.xda-developers.com/showthread.php?t=1947376&page=5
Is anyone getting LTE working on CM11? Any help would be massively appreciated if you are. Otherwise I guess I'll wait for further updates.
Thanks all.
EDIT:
For the record, I reflashed, reupdated o2 settings, and rebooted and now get LTE signal. Should have tried before posting. My apologies. Please lock/delete thread. TIA
So you're back on cm 10.2? Or does it work now on cm11?
I'm using CM11 nightlies on my GT-I9195 LTE and LTE has always been working fine.
okay that's weird. i got an upgrade from my provider that includes LTE up to 16 mbit/s... but my s4 mini never connects with 4G...
it wasn't a problem because with 3G i reached up to 14 mbit/s...
but so theres the problem with my provider, not with my phone.
