[LTE] Grey data connectivity

Is it me or do I seem to always have an issue with data and my phone. There are many times when I go to pick it up to use and the data, either 3G or 4G, is greyed out.
I've noticed it even if I switch my phone to CDMA only.
Any suggestions on how to fix it other than the obvious reboot or airplane mode?

Unfortunately, this might just be reception issues in your area. I have no LTE problems where I live.

That's what I'm thinking. The phone may just not know what mode to chose cause I'm in between the two.

I have to bump this thread. I'm sick of this. I can hardly ever send MMS messages when I'm on WiFi.
I'm not in a 4G area, that I know. I was successful in updating my PRL which I thought fixed my issue, but didn't.
It's not like I have no signal, 1 bar, -90dBm in my house. Even switching the phone to 3G only doesn't fix this. Rebooting is my only option, as turning on airplane mode doesn't help.
Does anyone else have issues connecting to data? I'm tempted to root, just to flash a new(er) radio, but I don't feel like restoring my phone.

Have you tried updating to the new radio?

Whoops! That's what I get for opening up threads in multiple tabs. I replied to the wrong thread.

Haven't tried a new radio, still would have to root it.
As for the wifi sleep policy, it's set to always. I dunno...

Yeah, that was my bad. I had multiple tabs open with different threads and posted in the wrong one.

I live in a spotty 4g area so its constantly switching from 3g to 4g and before it locks onto one signal it always does the stupid grey bar deal and sometimes it won't lock on at all even though I'm in a strong (3g) area. Restarting the phone works sometimes. All I know is that it better be fixed soon or this phone will be going back.

Yup, this is the issue I have. I can have strong 3G signal (all bars grey) but it just won't connect. Airplane mode sometimes fixes it, but I usually have to reboot the damn thing.

We have 4G here in town, but I live on the outer city limits. When I get closer to town I get 4G.

I know where I live sometimes I need to reboot my phone for it to change successfully from 3g to 4g... Another thing people suggest is toggling airplane mode on and off to make it pick up signal

I thought about taking it in and replacing it.... I don't have any reception issues, just this issue with the phone not wanting to get on data about 50% of the time.

How to force LTE only on Sprint Galaxy Nexus? [Without Root]

Is there a way to do this and if not is there a way to do by rooting the phone? What is the best and simplest way to root the phone if need be. Like a stock root by just rooting it without flashing new ROMS.
I have decent 4G LTE coverage like 2 or 3 bars but my 3G coverage is like 3 to 4 bars so it keeps switching over to 3G. When I am in the right spot like upstairs rather than downstairs the 4G LTE is blazing fast. If I had a program to keep it on 4G LTE downstairs that would be great.

Dialer>*#*#4636#*#*> phone information> scroll down and choose lte only from the menu
Hope it helps

That won't stick.
And you can't force LTE only even with root.
LTE is data only, how are you going to receive calls and texts?

Dialer>*#*#4636#*#*> You have to have MSL number which I can't get on the Galaxy Nexus Sprint Version. And also I heard that it does not give you an LTE only option just the same one in the system [LTE / GSM].
Also I don't care whether I can make or receive calls. When I just want to use the phone for DATA at the moment I use Foxfi so I can just use it as a wifi hot spot. When I am done I can put it back on to 3G.
Anyone know how to get the MSL number for Sprint Galaxy Nexus?
Also you are telling me with root or no root there is no way to force the phone to stay on 4G LTE? I find that hard to believe and if it is that is sad.

It is not possible to do LTE only on this device.

Why is that? Can anyone create an APP for it or is it hardware?

Is there no way to build a ROM/kernel from AOSP that has the CDMA radio disabled? does the LTE radio require the CDMA radio to be transmitting?

Exactly, I mean if the radio can be on 4G and not 3G why can it not stay on 4G? Is it still on 3G when it shows its on 4G like on both of them on at the same time? And if that is the case can you force the weaker 4g as primary and leave 3G on in the background?

Anything at all here? Will some of the apps on the market work for the Nexus? What if I get msl code and use 4G only in that? Has anyone tested that?
Sent from my Galaxy Nexus using XDA Premium App

It uses 3G and 4G concurrently, if not how are you going to receive calls and texts?
Like I already said, changing it to LTE only in the *#*#4636#*#* menu won't stick, regardless of whether you are rooted or not.

part 2 still stands.

Yes I do not care about voice calls. If I want to download a movie or something I do not have to have calls during that time. So has anyone found any new information or app that will perform this function to Force 4G on the Galaxy Nexus? Again I do not care about Voice Calls.
Sent from my Galaxy Nexus using XDA Premium App

All the Mifi hotspots can be set to do LTE only. This should definitely be possible especially since support for voice through data is right around corner.

Okay I rooted my phone, and got MSL code, but now when I go through all the settings I still do not have LTE only setting just hybrid as my last option. I have been reading some forums and some people with Sprint phones have LTE only option. Is this true? Do I need a paticular ROM? Anyone figure this out or have any idea?
Best,

This works on my Galaxy Victory for Virgin Mobile.. it does mean you can't recieve calls but I use it anyway..
Download an app in play store called "Show Service Mode" - costs a little $
Open the app
Select the third box to create a shortcut
Go back to the main screen and click the new shortcut
Select LTE band preference
Then select LTE ALL
DONE!!!
To switch back to normal open the same shortcut and choose automatic

do you use the sprint connection optimizer?

just curious of people use it or not? On the EVO LTE you wanted to keep wi-fi off as it tended to cause problems when switching from wi-fi to 4g (the problem being you would not get any 4g signal.)

Nope. Annoying having that crap pop up constantly

mine is checked (which I believe means it is on) but I never have anything pop-up to suggest a different network etc. It does automatically switch to wi-fi given the chance.

I can't stand it. I have to disable it then remove the apk to actually turn it off. Very frustrating. My girlfriends Zte Flash won't allow you to disable either. Kind of a crappy "feature".

I drive around doing property maintenance all day and have lots of hotspots so leave mine on. I am surprised at how many times I pull out my phone and am on a wifi network, and no pop-up for me either. There is a setting to disable that somewhere.

It seems to me that you need it to get 4g. Am I wrong in this observation? Is it just coincidence that I don't pick up 4g when its off?

question about 3g speed and 4g connectivity

Hello,
I have been around for a while, since my htc hero. And I've trusted xda to fix the many issues that manufacturers leave in. However the are a few issues with my new Galaxy S III that are driving me mad and if I can't fix them I may have to return it.
So far my speed is terrible. My 3g speed is half that of my wife's Epic touch. My 4g speeds are fine but will randomly switch to 3g (and with lte there is no refresh button like wimax, so I have to use airplane mode). And 4g is slower than 3g when I try to download from the play store but fine in the browser.
If anyone can help that would be great. I can't search all that well from the app and I am on stock tw 4.1 just rooted. I already fix all of the prl updates and stuff.
Also sometimes a green checkmark appears in my notification bar and says preparing network.
Other than this annoying network issue I really like this phone. I would hate to have to return it for the lg optimus G

Your wife's phone us on wimax yours is on lte. What you explained sounds like lte towers are being worked on and upgraded near you. Lack of signal going into and out I went through that for about 4 weeks then lte lite up perfectly after that.

Mobile data not working

has anyone had the issue where their phone won't connect back to 3g data?
when I reboot my phone 3g will work until wifi kicks in. after I turn wifi off 3g comes back, I can call and text but will not download any data.
I have tried Odin back to stock. wiped everything including recovery. I have tried flashing every combination of modems and kernels. all same.
however one thing I will note. I have not been able to get a successful modem flashed in Odin. it keeps failing. so I flash in twrp.
I also wiped the activation data via ##732# or something like that. had sprint reactivate my phone too..
perhaps someone could shed some light on this?

I just got my Note 2 like 5 days ago and mine does the same thing. Its very annoying and its gonna be exchanged today for that and other reasons.
Sent from my SCH-I535 using xda premium

hmm. I wonder if it's network related..
is your phone stock?
-Wizzle

Okay here is the skinny. It is network related. My wife's stock s3 does the same thing. If you are in an area without lte and your phone under mobile settings is selected to lte/evdo/cdma it will connect to ephrd13. Which is enhanced 3g. When you come off wifi or a phone call sometime it will not reconnect. You can toggle data a few times and it will reconnect.
To solve this issue, under mobile settings I select evdo only setting being that I do not have lte in my area. There is no change in speed between the 2 3g networks.
This info is from self diagnosing the rooted note 2, a stock photon, and a stock s3.
I have had sprint reset the phones as well as the ##data# trick.

When I say evdo only I meant cdma only. Ehrpd13 is the handshaking 3g for lte. Some areas have lte in the towers but no ehrpd13 so the lte is not turned on yet. Basically ehrpd13 and lte are like cookies and cream lol.

When the 4g network matures as it will the 4g will get better as the 3g.
You can always go to I think s4gru.com. That site shows when and where lte will become available. Plus they will be able to help you better there than xda.
As for sprint customer service, they are laughable at best. 4 people I spoke with didn't know what ehrpd13 was lol.
