I brought my phone to the Sprint repair store to have it looked at. I was having crappy data speeds and poor phone signal.
The tech took it and ran some tests, he said it failed the data speed test.
After 45 min he said he changed and separated the voice and data profiles. I asked if I was to reset the phone would the changes be gone. He said no it's done server side to the account. He said the only thing I might notice is a little lag when I push emails to the phone.
My phone signal does seem a little better and data seems a bit faster. My question is what he said make sense? Or did he just blow smoke up my ass to get me out of the store.
i would like to know this too...
updated PRL and Profile maybe? Settings/about phone/ system updates
Some things have to be done by Sprint on the server side.
check your underwear for smoke stains, bro...
Can resetting the data profile and so forth on their end improve/fix some provisioning/data issues?
Yes.
Is it going to fix the current problem with Sprint's data speeds and/or LOS?
Absolutely not.
LOS is a problem with the firmware on your phone.
Data speeds are a result of an aging network that cannot support the amount of data users are using. [Although with Sprint Network Vision that is changing]

I wasn't having LOS, it's was more crappy data speeds and low call signal strength. In my case I came from using the Epic 4g and where I lived I was getting 3-4 bars compared to none to 1 with the ET4G.
With my old phone my upload/download speed was twice of what I'm getting now.

I understand that, I only mentioned it so everyone was clear on that.
It's possible that a re-provisioning could improve your situation but it pretty much just sounds like your reception is just Samsung's crappy radio firmware.
You may want to take the device back to Sprint if the low radio reception continues and maybe they can swap it out.
The data end of it is just what I said above.
I know there are quite a few things that they can do server side (for example, your voicemail can become corrupted on their servers, which only they can reset. Long freaking process.) but this seems to just be a load of smoke.
Bars don't mean much from phone to phone, I've made calls and sent texts with no bars. I've also seen my phone side by side with other Sprint phones with mine showing 1-2 less bars but having the same dbm. Data speeds HOWEVER have just sucked since day 1, sometimes I'm lucky to be faster than dialup.

Hmm...I've been a sprint tech since June when I got hired, and I haven't heard of something like this yet. AFAIK, voice and data provisioning are already separate, using two independent programming menus. I'll ask my fellow techs tomorrow when I'm in if this is indeed something possible.
Keep in mind though, there are A LOT of internal tools/sites at our disposal, so many that even experienced techs are discovering them for the first time occasionally. They only cover so much in our training. Many are redundant (old tools that instead of being revamped with new features a new tool was released), but a lot of times they have one or two unique pieces of functionality that still make them useful.

Hey guys I'm completely new here as a member. But over the past month or two I've been reading on XDA to see Q & A's about the Galaxy Nexus.
So I bought this phone on launch day after going through massive hell to be able to even purchase one. Long story short went to 3 different stores back and forth and at the end of the night, GOT ONE.
I've been having the huge signal issues with the phone like everyone else since Day 1. The issues with the 3G/4G switching off, extremely poor reception, stuck on 2G (calls/text only) and a lot of times, not having a signal at all!
So after looking on the forum, I decided I'd wait it out and not root my phone/update to 4.0.3/update radios, etc. I've also talked to Verizon Reps over the phone and they wouldn't really help me out. I've gotten so frustrated with the phone that I almost wanted to return it and get a Rezound or Razr JUST to be able to have a 4G signal.
YESTERDAY THOUGH, I spoke to a 2nd Level Tech Support person and we went through all the steps the 1st Level Tech did and what not to make sure I had my Data Connection on, battery pull, LTE/CDMA on and not CDMA only, etc. you get the point. One of the other things she told me to do was to make sure in the Mobile Network Settings that Data Roaming was checked. I told her that it wasn't because it said that I will incur charges and what not. She told me as long as I'm in the United States, with it checked, I won't receive any extra charges. It's only if you leave the United States to a different country.
I asked her why should it be checked out of curiosity and she said that by having it checked, it searches for any and all towers around you instead of trying to be locked on one or something like that. So I did that. After, she told me it probably won't work to get 4G signal yet because of the LTE Power Outage that was going on the same time I was on the phone with her.
Well later last night the LTE Power Outage was fixed and starting last night I started seeing 3-4 Bars or -82 to -96 dBm continuously. Well waking up this morning for work and throughout the entire day today, I've been getting a consistent 4G signal (with 3G coming on for 3-5 minutes about two times, then back to 4G) My speedtest results were great. Getting 16-23 mbps with my 4G signal in Orange County, California (Piggy backing off of LA).
Now I have no idea if it was 3 things. The Power Outage coming back on fixed it, the new extended battery fixed it (haha joking) or the fact that I turned on Data Roaming fixed it by connecting to all towers near me. Either way I've been completely happy since last night and all day today with it working. I literally lost signal once and it was for a good 5 seconds lol then went back to 4G.
Has anyone else turned on their Data Roaming or has seen their signal start to work after the LTE Outage? Let me know. Because I know that I didn't update the software to 4.0.3 or any other software update on it.
Thanks everyone and I hope all the Nexus phones' signals get fixed soon!!! This phone is completely amazing but without signal, it's like a paperweight.
Having to turn on data roaming to increase signal seems like bollocks to me. It would be interesting to try turning it off and check if you see any difference, now that the shortage is over.
Thanks for sharing, anyway
Yeah I'm not sure what fixed my phone but its now fixed. I'm getting full bars of 4G as I'm typing this. Did you check the Roaming Data and did a soft reset to see if that worked?
Sent from my Galaxy Nexus using XDA App
so wouldn't "roaming" mean that if you're in an area where verizon's towers aren't sending out a good signal, you'll pick up on sprint's towers if they're stronger?...
I believe so. Or something close to that. The rep said that I would only get roaming charges if I go out of the US with the Roaming check marked.
She's the one that told me I should get a better signal with Roaming check marked in. Then after the outage 2 days ago, that night, my signal was working and I was getting a constant 4G signal with good strength.

Gonna try this, thanks for the heads up.

Just turned this on at work and went from one bar of 4G to three. Don't know if it is a fluke or placebo, but a difference.
Edit: Maybe I spoke too soon. Back down to one. I'll wait til I get outside. Don't have the strongest signal in this building anyway.

@OP where in orange county?? I live in HB.. my signal is not that great there.. but in Irvine its full bars.. I never really had an issue to my knowledge at least.. may give your method a try at home to see if my sig improves.
I live in Garden Grove and Anaheim. But I'm constantly traveling throughout OC on an ambulance for work from Whittier all the way to San Clemente. So my signal ranges.
Funny you say that because I usually get horrible signal in Irvine on the 5 or 405 freeway. Haha.
Yeah I would try the roaming checked. Do a sim pull, battery pull, and see if it works. I assume that's what worked for me.

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...

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.

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.
I am within 14 day window to exchange phone but I have to ship back to sprint due to purchasing online. I have Sero account so no purchase was possible through sprint store.
Here is my situation.
3G speed has been slower than I expected since purchasing the phone. My 3G speed has averaged between 125 to 350 kbps throughout a 24 hr period over several days. I am averaging between -90dbms and -95dbms signal level in most locations in which I travel on sprint using EVDO A. I have taken the phone to the sprint repair center twice but they don't run any tests other than speedtest. They tell me it is the network and wait for 4GLTE. There are no issues on Wifi that I can see.
I would have accepted that answer but on the weekend I met up with two friends who are also on sprint. One has the same SG3 and the other HTC Evo 4GLTE. While sitting at same table and rebooting our phones, we ran some speedtests over hr period and my phone was consistently slower than the other two. I know there are many factors but we had the same settings to our knowledge. The HTC was faster followed slightly by SG3. They were ranging from 500kbps up to 1600kbps while mine were in the 250-300 range using the same servers.
I have installed JB update stock using modem LJ7.
1 What is considered good to excellent signal strength?
2. What can I check for to determine if it is the phone since the service center is no help. Or do I send it back and hope for best on next phone?
I don't want to try a different modem until out of 14-day window.
Any suggestions?
Thank for any help
Has nothing to do with phone, it's network issue.

It can and sometimes does have to do with the phone. IF a radio is bad, antenna is bad or a number of factors.
In this case i think he has done a good job comparing location and devices. All things can never be equal since these things are mass produced on assembly lines. But from his testing it does make me think theres an issue.
I also played with many different stock ROMS and modems back when i had a GS2 and some modems did work better then others.

So what I would recommend would be to try out the different modems that are available in the Android Development section. Just because your friend has an SG3, it doesn't mean that you're going to get the exact same result. I know it doesn't make any sense but each phone is different. I have absolutely abysmal 3g coverage with one modem but with others it gets better.....and the modems that work well for my phone are different than the modems that other sprint sg3 friends use........give it a shot and see if maybe a different modem might work better for you.
Take it back and test in the store. Run some speedtests with the demo phones in the store if possible.

The only thing that trips the counter is if you Odin flash a custom recovery or, as it is appearing, if you flash a custom kernel. If you flash anything through a custom recovery then it shouldn't trip the counter if you were to use triangle away to reset the counter........I flash files regularly through TWRP and it doesn't increment the counter.
actually a lot of people who have the Evo LTE have reported bad signal and internet. my sister has the Evo LTE and i have the Galaxy SIII and we could be in the same place and she'll have really bad internet while i will have pretty good data speeds

That can be explained by the switching glitch in the EVO LTE that would go to 1x and not back to EVDO or eHRPD/LTE. Mine did that and i got a GS3.
I have since applied updates to the EVO LTE and it doesnt appear to do this anymore.
In my case it was not a signal strength issue as your saying but it was a network selection issue that caused the device to get stuck on 1x. But then again that was my unit and it was a few months ago..
In my opinion bad signal would be the lack of signal. But in this case it was good signal with poor system switching.
manually update your prl to 00001 its given me way better service ever since i did. my gf gets no bars in her house mean while i get 2 to three bars with good 3g speed and i have not roamed since.

TO ALL!!!! this is a call to action. I too, like many others are experiencing unacceptable data speeds while on 3G and in great reception while using the Galaxy S III. the speeds I should be receiving are 1.5-3 MB/s but instead I am receiving around 128Kb/s in the city and within excellent service. We all have to pay a 'Premium Data Add-On' charges just to own these phones and this is unacceptable. Please write an Email to [email protected], vice president of customer experience at sprint and let him know what you are experiencing. Maybe if enough pissed off customers write, they will finally listen!

Just out of random curiousity, did Mr. Adriano give you permission to put his email address on a public forum?
I can understand privately giving it to a friend or someone who might need assistance but to put it on a public forum..
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

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 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...

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.

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.
