fix for disconnect from 3g network - Sprint LG Optimus G

For anyone having issues with getting disconnected from 3g network. If you find that you are continuously getting disconnected from the 3g network on Sprint, goto your network settings and change your preferred network setting from lte/cdma to CDMA only. That should keep you on the 3g network without having to continuously reboot all the time. It's not a problem with your Rom I think it's an issue with the lte network. Being that it may not be up and running in your town. Yes they are advertising it but it is not online across the entire country yet.

I remember having this issue, as well as on my LGOG, also on my S3 and LTEVO. I just couldn't remember how I fixed it, and this was my method of fixing it. Thanks! :good:

This is only good if you dont want lte right? Lol

[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.

Data keeps switching between 3g and H+

Ever since I flashed my phone with the wicked rom .. my data has been do constantly switching between 3g and h+... I have my network type set to wcdma only and I have a strong signal but it still drops down to 3g
Before when I was on the stock rom it never did that.. I even had my network type set to wcdma preferred ..
Anyone having the same issue ?

That's completely normal. It only shows h when your data is fully active. Its a good thing. The only difference is now your phone is telling you the truth.

Oh is it normal ? I didn't know since on the stock rom it never did that ,always displayed 4g.
But what would it drop to 3g if I have a strong signal always
Sent from my SGH-T999 using xda app-developers app
Yeah dude. T-Mobile does that they call their hspa+ 4G. Technically anything that is not 3g is considered 4G. The reason you are seeing this on your new rom is because the stock tmobile rom will only display you in 2G or E for edge. Or 4G for 3G and HSPA+ otherwise known as 4G. The majority of customer roms will tell you what you are currently on.

[Q] force 3g on GS3

I recently rooted my GS3 and i have been trying to figure out how to force 3g service on it any help? since i can only pick up 4g in certain areas im tired of the EDGE 2G.
Im pretty sure you cant, seeing as hspa+ is still technically 3G or WCDMA. So I think your stuck with Edge for now... Until T-Mobile does more service upgrades in your area... Don't worry, I get crappy service wherever I go, and I have the worst service here at home... Should have went with Sprint...

You could try, but AT&T uses the same thing "HSPA+" which is really 3G, but they still call it 4G, and that's what would show up on your status bar (it would still say 4G), so I don't know if that'll work... You can give it a try though. I'm actually going try it our right now, and see how it works. I'll keep you posted. :good:
Have that issue too and don't count on them upgrading anything anytime soon. Just wait till your contract is up and make that switch

I guess you can take the 4G plan off your phone and be throttled down to 3G speed... That's it.

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.

The problem is my area does have it but at my house its very weak. My ohone wikl display 4g but it wont download anything untio it switches to 3g.
Sent from my SPH-L900 using xda premium
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.

Signal dropping constantly

So my mom has this phone, and me and my sister have HTC ones. Our phones work fine at home, and we just got Lte coverage a few days ago, so that's been nice. However, my mom's phone recently has been dropping basically every call no matter where she is or how much service it says she has. The signal bars show a red x, and usually given time the service will come back, but sometimes it takes a restart. I've tried updating profile and prl, and the best the people at the sprint store could do was tell me that there is supposed to be a software update coming to fix it. The phone is completely stock. It doesn't seem like the network cause the other phones work fine. Has anyone else had this issue? Any ideas on what we could try?

You must have weak LTE signal. Go to Settings>More>Mobile Networks and tick it to CDMA. If she wants LTE she'll have to do this manually.
Sorry but it's just the way this phone is.

You can try to flash the ZVC radio from here. http://forum.xda-developers.com/showthread.php?t=2230106 but you'd have to root/unlock.
Other option is to LGNPST in the same thread under "Additional info". That's about all I got.
