Hey guys,
So i'm new to owning Samsung galaxy phones. I do really like my phone alot, the only downfall so far with is my signal us HORRIBLE! I had the evo and evo 3d and my signal wasnt to bad. The I bought the iPhone and had good signal but since i'm a sprint customer I had extremely slow internet. Found out how to make my iPhone run on Verizon signal and was fast. Well I got bored with it and got this. (sorry for long story, at work and bored). So anyways is there a way to help my signal. All my phones besides this one had full signal at my house this phone only gets about 4 bars and it seems like my wifi reciever is weak to, hardly picks up my wifi at home. Id really appreciate the help,
Thanks

Hmmm....that's interesting. Other than slow 3G and spotty 4G service in my area, I've never had signal problems and definitely no problems picking up WIFI at home. In fact, I normally connect to my WIFI before I even pull into the driveway at home.
In regards to phone signal, have you tried updating your PRL in settings?
I just got it on Friday and the prl updated its self, haven't tried recently. Is there ways to reprogram the radio. I've had both my evos rooted, I understood flashing roms, but never understood when it said something about radios.

try to flash a newer modem with ODIN! but my best is with FE22 but that will depends on what area you are in
Some basic info: Sprint SGS3; rooted, manually updated to LG8. Otherwise, stock.
Since then, I've noticed that my phone doesn't "hold on" to 4G as well as it did pre root and update. For example, the 4G icon will be next to the signal strength in my status bar then it will disappear, there will just be signal strength with no connection indicator then either 3G or 4G will appear. I don't ever remember this happening before root/update. I haven't flashed anything else on the phone, and the main reason I rooted in the first place was so I could easily tether.
Has anyone else had this same issue?
Its funny that the LG8 update was supposed to help users that were having LTE connectivity issues... this happens to me on occasion too. i would venture to say that a combination of LTE still being in early development and coverage being spotty at times even in areas where u may have gotten full coverage at one point plus the "Connection Optimizer" that often jacks with ur data connection switching between wifi, 3g and 4g(LTE)... try doing a ##72786# to reactivate ur phone on the network... this will automatically re-associate ur data profile with the network and update prl info as well...
+1 I have the same issue

Thanks for the reply. I'll try the ##72786# and report back with results.
You make a fair point about LTE still getting off the ground, but I will say that pre-root/update, my phone held 4G consistently. Whatever the issue is, hopefully it will sort itself out soon, or enough people will have the same issue that it spurs some action on Sprint's side.
I'm in Houston, FWIW.
Edit/Update: ##72786# seemed to do the trick. HOWEVER, about 15 minutes ago, I attempted to turn on WiFi Tether. My laptop connected with no issues, but about 5 minutes into it, neither the 4G nor the 3G icons appeared next to the signal strength meter. ##72786#'d again, just to see if it made a difference, updated PRL and Profile. Things are holding steady so far, but we'll see how long this lasts.
I'll try to update later in the day.

Glad to see it worked. This is by no means a permanent fix. As u flash different roms thru out ur phones life span its a good idea to run this code every so often as flashing can overtime degrade baseband performance as those files dont get replaced with a rom but different roms interact with those files depending on the tweaks made at software level...

I can't wait either. For those that have 4G i'm curious as to what the battery life is like and how much faster the network is on the SG3.

The issues cropped up again throughout the day, though not as frequently. I made a post in a reddit subforum and someone there suggested I flash new radios. Any idea on whether that would work, and if so, where/how/what?

It won't, till Sprint gets their network done. I've been back and forth on all radios, no difference IMO.

I am up here in Sugar Hill. Sprint Map shows you deep in LTEville. I worked in Tucker last year when a co-worker got a Verizon Tunderbolt. His 4G was screaming. He was getting 40+ down!
But the map also shows Cumming in LTE land so I drove over there just to see what LTE looked like and I saw the icon flicker on for about 30 sec. but it never really was there.

Just flashed back to LG2, so I'll update later and see how things are going.
So today I have had issues with connecting to Sprint's network. In a city near mine, they are upgrading to 4G. My phone has been going from full signal to zero signal within seconds. It is killing my battery life. I am running CM10.1 with the current nightly. I restored a previous version of CM to see if it was an issue with the ROM and I was getting the same results. Do I need to flash the radios or leave it be? Could it be because of Network Vision? Is there a way to back up my current radios in case something goes haywire?

Its most likely a carrier issue....make sure you have the most current radios installed which are FD02 if i remember correctly....other than that its a very rare occurance that software would affect your signal...probably due to the work that they are doing in the area....turn off LTE and see if the 3G signal does the same thing...good luck let us know what happens
Its sprints terrible network.

I've turned off 4g, reconnected with airplane mode, restarted my phone, fixed permissions. 3G is the same. I hardly have any service. The thing is, the past couple weeks the service here has been awesome. Then yesterday, this.

Like i said its most likely the work that they are doing .... Give it a couple days because the same thing happened to me when Verizon was putting up their towers near me when i had my thunderbolt....give sprint a call see whats going on
...check their website see what it says for your area....for what its worth I'm 99% sure its their doing

Well, I have confirmed it to be on Sprint's end. All it took was a quick drive around town to pick up a different tower. My buddy has a signal booster in his apartment and I was picking up full bars there. Here's hoping LTE is close!
So I live in the city. Right now I'm using MOAR v4.01 and I cannot achieve a connection other than 1x no matter where I am in the city. I had this problem on other ROMS so I don't think it's MOAR.
I was using the Anthrax Aosp rom a few months ago and noticed I achieved a 4g connection on the upper east side but ever since then I cannot get higher than 1x.
Is there anyone else in NY getting a 3g or 4g connection? Does anyone know what I can do to try to fix this? I am using the MD4 modem (had the problem on MB1 too) and update my profile and prl often. I am really getting frustrated paying for services I can't even use. I am hoping that I won't have to unroot and reset my flash counter to bring the phone to a sprint store.

I'm nowhere near NYC (in fact, Southern California is pretty much as far away as you can get from NYC without going to Alaska or Hawaii), but it sounds like Sprint might be updating their network. I know in many areas (myself included), Data services were extremely crippled when they were installing 4G. I would regularly get 1x in areas where I would get decent 3G. Then a few weeks later, the 3G was back. Then a month or so later 4G was up and running (it's pretty nice here at my work desk). Others have reported similar issues when the network is being upgraded.
So maybe it'd be worth a call to Sprint to see what's up with them. A part of me doubts that most of NYC would be upgraded at once, but maybe in your area there's work going on. It's worth a (relatively) quick call.
Yes, I get 3g and 4g depending where I am. I'm stock rooted md4.
Had that issue once but update profile and prl over wifi fixed it for me.

I emailed them and they told me there is network outages in my area, but then the guy above me just said he's getting a 3g and 4g connection. Sprint really frustrates me. When I got my phone, it would say I was connected to 3g but after doing speed tests I would only get about 115kbps down. Now I'm using MOAR and it shows 1x and if I do a speed test on 1x its about the same. However, I used to get a 4g connection on 44th street and 6th ave but now I don't. I think I'm gonna go to the store today and ask them. If they tell me to bring my phone in I'll have to unroot it and reset the flash counter :/

Yes, certain spots in lower Manhattan I get signal but can't use the service. It just don't work. Text won't send or calls won't go thru.
Yes sprint turns on and off the 4g.

So I found out what was causing the issue. I went into the ##3282# menu and navigated to Others > HDR/1X Selection and turned it to Hybrid mode and now I can access 3G and I'm gonna test 4G after work.

At first I thought it might have been my rom, but it seems it's happening with my GF's note 2 also.
Coverage we used to receive in some areas is almost completely gone. It will show signal and the 4g symbol but basically have NO internet service whatsoever.
On a better note, we've been receiving coverage in some areas we don't usually have it.
I'm hoping this is just a temporary thing due to the attempts to upgrade towers for LTE.
I don't know if it's because of the UVBMB4 update, but t-mobile service has been pretty crappy lately. Period.
We're in the San Gabriel Valley area.
Link for older UVALL4 modem below, people seem to experience better service

I believe my service has suffered as well. Before the last update that enabled our Lte radios, I had great speeds, now it's slowed Way down. I'm in San Diego CA. Hope that it's just as the Op said, LTE towers being updated and what not.

Definitely have noticed a deterioration of service over the past month here in NYC.
Its because for some reason that new LTE APN is slow on HSPA+.. unless you have LTE in your area switch to the EPC APN. You can find the settings online. Its litter ally consistently a difference of 6+ mbps I have extensively speed tested lol..... click thanks if this helped

I also had problems even with old apn.
Flashed previous radio and service is top notch again.

Same here, I thought it was rom related.
YES! My service has sucked royally for the past month or so. Data latency/hangups/slowness, and the signal will just completely go away sometimes. I noticed that it started as soon as I flashed the most recent radio too, I'm about to go back to the old one.
Count me in, even my regular phone reception went from 4 bars no 1 or 0!
Can anyone point to towards old radio to flash? I go from no signal downstairs to full bars upstairs...theres an obv issue with new radio.
Yup I've noticed this beginning this week I've made zero changes to the phone. I used to get full bars at work and this week it bounces between full and 1 bar regularly. Theure messing with towers for sure

I'm also experiencing significant decrease on data speed. Has your data speed improve after flashing with older radio and APN setting?

I was getting about 9/0.6 and with flashing back Im getting... 14/2 Though Ive been on HSDPA 15 & 21. Though Im not getting 4G as much, but it was sporadic anyways and I lost signal...and now I am not. So, Im happy now even though I am on 3G. However... in my corner big red has same problems as they wanted to not have tons of towers in this corner and theres only a ATT Tower....for a decent distance. basically reception fringe. though I am a new subscriber so i haven't experienced normal TMO, I literally got my device yesterday around 6pmish but it def wasn't normal and flashing previous radio did fix it like it solved everyone elses issue

my problems started last friday. i have limited to no service at all; no data, no voice, even no signal at times (circle with line through it, not just no bars). when i do get a signal, the phone refuses to register on the network. when im at home, i have intermittent service. i miss calls, texts wont send, if i do get a working call, it drops after a bit. there are times when it works fine, even on LTE but it never last long. went to the tmo store last night and they gave me a new sim which didnt do squat. already done the factory reset option (twice). phone has never been rooted, all stock. im in the KC metro so not like in the middle of nowhere. they said my next step is a warranty replacement phone if the sim didnt help. not sure if my problem is at all related to everyone elses in this thread, but yeah, service has sucked.
One of the issues, especially if you switch from 4g to edge to gprs a lot, is a setting in the new modem.
It's something called acquisition order. It has 3 settings:automatic, gsm_umts, umts_gsm. In short it tells the phone what kind of network to prefer. It will search for and use that type of network first.
Prior to the latest update it was set to auto. Now it is set to prefer umts. For some reason this has caused an issue I've come to call phantom 4g. Where it'll say 4g with no bars and no data service.
That is my guess. I'll look into it further.

Thanks guys for the heads up on switching to an older radio, I dont have LTE in Miami yet and was having slow internet for the last 3 weeks, I just switched and wow! What a difference. I'm also using the Epic APN.
I also noticed that speeds were degraded after the update. However, there is a simply fix to make your web a tad bit faster....
Go into your network settings, and switch your mobile network from LTE/4g/3g/2g to just 4G/3g/2g
your device will stop looking for an LTE connection and will just utilize HSPA+
Made a world of a difference on my own device. Connecting to the play store, opening web pages, everything was right back to where it was before the update.
Obviously if you live in an LTE area, there is no need to do this...

So I'm gonna be a noob here for a sec. When people say they are flashing the previous radio (I'm referencing the link that was posted) are people just flashing the modem from the section under the most recent? (the one with the January date on it). Just thought I would ask. Better safe than sorry. Thanks!

Yup, radio is synonymous with modem in this case. UVALL4 is the previous version.
