Sprint NS4G Users Please read...

So my wife has the NS4G and it has had intermittent problems with network connections since the day she purchased it. Full signal on both wifi and 3g...unable to connect to network. I imagine you're familiar with this problem.
If she swaps for another NS4G will the issue alleviate itself? Is there a rom out there that fixes this...currently running oICS. Any help or advice in getting a different phone from Sprint? It has been 6 months with this phone. They actually offered her a HTC Hero today...that's what got me enraged enough to get involved.
Any and all help is greatly appreciated.

Try latest radio in 4g dev section (kL2). I've had excellent results with this radio.

Signal Dropping Constantly

Hello,
I'm at a point where I don't know what else to do. My signal is dropping and or changing from H to H+ to 3G to no connection constantly. I'm supposed to be on LTE. Everything had been working fine until this morning.
Here is what I've done to try and fix the problem:
- re-flashed ROM (Liquid Smooth, Paranoid Android, etc) Same results. And when I say I re-flashed I mean I started from scratch, cleared everything, etc.
- flashed different modems (3)
- went back to stock
- went to AT&T and tried a new SIM card
- pulled battery, pulled SIM, etc
Everything leads back to the same performance which is that my signal is not stable. I'm in NYC so I know my signal should be stable. It has been every day until today. And of course I did speak with ATT when I was there today and they said that there are no issues. I know they're right because every phone in there was getting LTE.
So now I'm thinking it's a physical problem with the phone?
Any advice is welcome. Thanks in advance.

Hey tony i know the isues you having but one thing you have to understand is that Network carriers Label the 4G logos"4g" although you maybe in a Hspa/Hspa+ location(which is more of a 3g+) lol
as for the data connection drop this has been an issue with JB for awhile where the apns wont stick either on boot or time out etc.....
best bet to know if its your phone or not is to revert to stock and test it if stock keeps the data connection then you know the phone is fine if it doesnt then its just apart of JB issues more then half of JB runners run into this issue.

He did go back to stock...
If the issue is still happening on stock, I'd say have AT&T replace the phone.

Thanks for the replies.
Yes, at this point I've done everything I could think of with regard to trying different scenarios. I'm definitely leaning towards the fact that perhaps the phone itself is on the fritz. Unfortunately the phone is out of warranty so I can't just have it replaced. I'm not due for an upgrade until June. And I don't have insurance on the phone. That sort of limits my options. AT&T did credit me $100 for my troubles, which is better than nothing. For an early upgrade I'd have to pay like $250, I believe (minus the $100 credit) in addition to renewing my contract with AT&T. Just thought I'd give you guys the breakdown.

Also, I want to reiterate the fact that I am in midtown Manhattan (NYC) where the signal is always full bars of LTE service. It's been consistent for months. This started yesterday (the signal drops) and has been inconsistent ever since. Obviously I've polled other AT&T users around me and they are not having any connection issues. And yes, I'v e gone back to stock more than once. The signal definitely comes and goes constantly. It's not just what the meter says on top of the screen. I use an application to see what mobile network I'm connected to and I'm getting the same inconsistencies looking there as I do when I look up at the signal meter in the status bar.

I had this happen too. Turned out my phone was broke.
I've got best buy's warranty and they replaced the phone. Sorry I'm not more help, but the fact that the phone just doesn't get a signal is a possibility. And I just wanted to let you know, you're not alone

[Q] Mobile data is not working..please help

I was running a Jellybam rom on 4.2 about a month ago and I decided I would upgrade to a 4.3 rom. Up until then my data was working normal and I could get 3g just about all around town. So after searching I settled for the ;latest PAC-man rom on 4.3 and loved the features it came with. Theres only one issue though...Now when i turn my data on and wifi off to access 3g or 4g I am extremely lucky if I even get a 1x signal. I am talking once in a blue moon this will happen. I know my data is working thought because when I download or send a MMS, I will instantly get 3g or 4g but as soon as it is finished, all data is lost again. I have tried going back to Jellybam and reinstalled PAC but nothing helps fix it. This is really becoming annoying now because I cannot use gps or pandora in my car anymore. Please help!

[Q] Connectivity problem on TMO US (CM10.x)

Hi all,
Even though I have the latest TMO radio, the 3G HSPA 21 connection is always very spotty. I've had flashed the phone with CM10.x ever since I got it. So no idea how it should perform with stock rom. The problem could be on three things: 1.sim, 2.phone 3.os.
I've test the sim, it's good with other devices. Are there anything else I can do to improve stability of the reception? Please kindly advise, thank you.
PS: I've learned that CM10 has problems with data connectivity; however, I've never found a workable solution yet.

[Q] anybody else having 4g connection issues?

About 3 weeks ago after installing the update of liquidsmooth 4.4.4 i randomly started dropping to 3g service in places that i normally had full 4g available. It has slowly gotten worse to where if im not on wifi, than the phone is pretty much useless. i normally have full coverage everywhere. so i originally thought that maybe something had gotten messed up on the update, so i did a clean install of liquidsmooth 4.4, and blackbird kernal and same thing still occurred. also tried carbon rom and slimrom, and no luck. so for the fun of it, i went ahead and reflashed the phone back to stock from backups and rerooted it, updated the modems and reinstalled liquidsmooth w/ blackbird kernal, and same thing. i have went through all the mobile networks settings and tried everything and nothing seems to help, idk if that update screwed something up or if its an issue that others have been experiencing as well, or if im just screwed and my phone phone is dying.... any help is appreciated thanks

I'm currently running OmniToad, and ran CM 11M8 for a short while. On T-Mobile at least, with the custom ROMs it's normal to see H+ only when data is being transferred; it will drop back to 3G otherwise. When I ran the stock ROM on the Relay, it would always say "4G" regardless of whether it was in UMTS (3G) or HSPA+ mode. Apps like SignalCheck or CellMapper will tell you which mode it is really in.
On the other hand, if data transmission is only going through as 3G, it could be a phone issue or a tower issue. Is LTE available in your area, or are they just getting it set up? I know when T-Mobile was upgrading the Chicago area to provide LTE, there were a few glitches here and there.
It was stupid for T-Mobile to brand HSPA+ as "4G" but that's a different rant.

yea LTE has been in this area for quite a while now, i had it with my S4 and it worked perfectly, i never had a problem with the service on the relay either up untill a few weeks ago the internet speed and and data coverage was great, not quite as fast as the LTE on my S4 but it was still more than adequate, i used to use the hotspot and stream netflix on my laptop. now i can usually get a text to send but calls usually fail and if i try and use the internet its impossible. it almost seems like its doing the exact opposite of what it should be doing, as soon as i try and use anything (not while connected to wifi) than it drops coverage to 3g/edge/ or to nothing at all. Im leaning towards the hardware failing side, but i figured i might as well give it a shot and post it and see if maybe i wasnt alone. thank you for your reply.
small note of background on me: first time posting ever in this forum but have been using the tools and roms from it for a long time, so im not a complete noob, but i definitely still have a lot to learn.
