Data Icons... Or lack of?

OK does this phone actually show anything other than 4g?
I am in a 3g area and I have not ever seen anything but the 4g icon.. Unless I put it in gsm only mode. But on auto or Wcdma mode it stays on the 4g icon.
Also it seems like I have issues with the Internet staying connected even when I have signal.
Also it seems like when I leave my screen off and turn it on the signal is higher than normal but goes down within a few seconds.
Anyone else notice this?

I am having the EXACT same issues. But, I am in a 4G area. Of course I got throttled by blowing through my 5G limit in a week--damn these new toys and massively restrictive internet access at work (financial industry). So now I am on edge for a while; but with the 4G icon up, I cannot hold a data connection at all. It goes on for a few seconds or such, then nothing. The upload icon is always on, but no download. I have to force GSM mode to maintain any sort of connection. The "Auto GSM/Wcdma" does not switch modes efficiently. I think it is continually checking for a 4G connection, thus resetting the 3G/Edge connection it is making. Very frustrating. . . I am hoping someone with make a Auto/4G/3G/Edge toggle so I can drop it on the homescreen rather than digging down for it.

Same thing here. Always on 4g and my wifi is spotty like the first poster. What's the deal?

5gb in one week?? That's insane usage u might need the 10gb option..
The 3g 4g network is the same network.. some towers aren't updated and some phones don't get 4g speeds but that's why it always says 4g

Turn off 3G but keep 4G/LTE enabled?

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.

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.

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?

Poor LTE signal, doesn't switch to CDMA, WiFi calling flakey

When I am home I have little or no LTE coverage, and even though in network its set to LTE and CDMA, it never seems to switch to CDMA even though I have like no LTE coverage at home. I never have more then 2 bars, usually I have 1 or no service at all.
And WiFi calling is unreliable as well. Often it says it's logged in but it doesn't work, it it fails to login and then apparently doesn't try to login again. If I turn WiFi on and off, the WiFi calling usually then logs in.
Anyhow, if I can't get the phone to automatically switch over to CDMA or if I can't get WiFi calling to work reliably, I'm going to cancel my sprint service since my phone isn't really usable at home. I don't want to put the phone into CDMA only since I would have to reboot the phone every time I go outside to get back on LTE
BTW, I get great LTE signal right outside my house.

staying on wifi doesn't really help me since wifi calling doesnt seem to be very reliable. Right now staying on lte seems like a better option since at least i can see when i have no signal. Wifi calling half the time says it's logged in, but it doesnt work.

you may need to get an airave since you aren't having service in the house. Just call up sprint and let them know what is going on and ask for one. Hope this helps!

I'm just worried the airwave well be as reliable as the wifi calling since it's essentially the same thing.
I wonder if there's something in android I can tweak that will make the phone jump to CDMA if the 4g signal it too weak.
I've noticed that if I have one bar and make a call, it almost always jumps to full bars as soon as I started the call. I'm guessing it's jumping over to CDMA. But why doesn't it do that when the phone is idle?

I believe that the bars you see before initiating a call are the data signal strength. When you press the call icon the phone Radio switches to cell 1x signal. which is usually pretty good in most urban areas and that is why you would see the signal bars jump to full strength.

My wife uses WiFi calling at home and it works very well. Maybe disconnect your phone from the router and do a restart/reset of your router. Then reconnect.

I've tried turning the wifi on and off on the phone. That will usually get it to work, but I have no way of knowing if it keeps working since as I said, it will sometimes say it's logged into the wifi calling but not work.
I tend to think it's not an issue with my router since every other online activity works great, including skype or streaming 4k videos on Netflix

The Wi-Fi icon is also a signal strength indicator. When on Wi-Fi the signal bars to the right are mobile data, then when you receive or make a call they switch to cell tower reception strength. When I'm on wifi and see only one signal bar next to it I know that I'm on LTE. if I see full signal bars and I'm not ona call, I know I'm on 3G. if I turn off wifi I will see either the LTE with 1 bar or 3G icon with full signal. this is at my house so its always the same and its a easy way to check how the signal strength indicators work on your phone. make sense?

I have two signal strength indicators on my phone. One for wifi, and one for call (or data). So i don't really understand how the wifi icon is also a signal strength indicator since there are two separate icons for that. Why would the phone show an indicator of the strength of data if I am on wifi and not using the data connection? On my phone (note 4, rooted but stock) i pretty much always have full wifi signal strength, but i have have zero bars/no service on the signal strength icon and when that happens, if anyone tries calling me, it never comes through. I don't have anything in the missed call log - just no call. Can't send a txt either.
The next time the phone drops to zero bars/no service and i happen to have someone else with a non-sprint phone, i'll try calling myself just to confirm the behavior.

Same for me. The signal and data quality is ****e compare to Note 3

So on the same network you had better signal strength with a note 3 vs a note 4?

how to lock network to 4g?

I have unstable 4g network at home, so my phone refuses to use 4g connection and it choose 3g.
I know *#*#4636#*#* and choose lte only will do the thing and it works but several times later it switched back to 3g (H/H+) and when I check it back it turned to Lte/gsm (Pre) again so I think I have to find another way.
It frustating me, since I just have 4g quota besides 3g.
