CDMA GNex Signal Issues

I just got my VZW Galaxy Nexus this last week and I've been experiencing signal issues. Often when check my phone, it will have no signal at all which can take some time to come on, and then its sometimes even longer before I get a data connection of any kind. I am in Lincoln, NE so I have 4G here which works great when it works. Is this a common problem with these phones? I rooted and installed CM9 that day I got it so I want to determine if I have bad hardware that needs to be exchanged or bad software that can be fixed. I found the 4.03 leaked radio on the boards here and flashed it, which has seemed to help some but I still have issues. What is everyone's experience with VZW and the GNex?

Common problem seems to be the complaint of a longer "connect to network" time, both on startup of the phone and if data is lost or switched down from 4G to 3G
The consensus seems to be that its a s/w issue that can be corrected.
Oddly enough, I was standing in the middle of our local shopping mall with no bars, yet did a Google search for "Verizon Wireless" (go figure, right?) and it came right up....no it wasnt cached. Just shows that our bar readings may be inaccurate, so who knows what else might be inaccurate. I also had my phone right next to a demo GNex at the Verizon store, and the demo was showing 2 or 3 bars of 3G, while mine had 1 bar of 4G......so which is better, 1 bar of 4G or 3 bars of 3G? Judging from app download speeds, Id rather have 1 bar of 4G anyday.

I have seen some comments about the bars in the status being in accurate, however when mine has no bars it seems to be that way. I am unable to use the internet, text or call which is an issue for me.
I also should note that I use JuiceDefender to control my data connection. While this should have no bearing on my phone/text connection, I am wondering if it may have some affect on the 4G connection even after I have the screen on for a bit.

I have 4g disabled and haven't had any issues. I'd try disabling it, restart and see if it happens again. Make sure its still disabled after restart.

I've been having big time issues with mine. Lots of time I go to pick up my phone and it has service, decent service, but won't connect to data. Once I'm connected it is not an issue but if I'm on wifi at home, and turn it off, it just doesn't want to connect unless I reboot.
Rooted and tried a new radio. A little better but still has been doing some weird things.

How long have you had yours? My biggest question that I'm trying to answer right now is if I have subpar hardware. Since the phone is only a week old I know I could return it to stock and easily get VZW to give me a new one. This may not be the case two months from now however.

I've had it since it's been released. The newer leaked radio is better, but it also does weird things too. I don't know if this is because I'm in a 4G town or what.
I don't get 4G where I live, but my buddies with a Bionic and Rezound do here at my house, albeit it's very sketchy for them.
Thing is, I'll have good 3G signal if I'm driving, but for some reason (at least with the original radio) it wouldn't connect. Still testing.
So far the newer radio has been better, but hasn't fixed my issue.

at my house it sucks a few blocks down or anywhere else its rock solid so i just wifi at home better for battery anyway

I hit dead zones where i really shouldnt be. Downgraded from 4.03 to 4.02 and the jury is still out. Might be overall software issue like OP said.

Sorry to hear you're having the same problem, but I am glad to hear this sounds like a correctable software issue and not isolated bad hardware. Hopefully VZW will make some improvements to their LTE network and get some radio updates for us soon. I'm in the same boat as you, the 4.03 leaked update was a definite improvement, but a far cry from being a total fix.
As for when my data connection is working...holy hell is LTE fast. I'm clocking it in at 12-16Mb/s, which is killing even my home cable connection. I was confused as to why something seemed slower when I was at home using wifi. I disabled my wifi altogether since I'm lucky enough to have an unlimited data plan still.

Big issue
I have replaced three verizon Galaxy nexus's....all of which, each day i switched...i was either on the phone with a tech dude or (2 of them) one on one at the verizon corporate store.
All of them confirmed that there is a reception issue.
I reside on long island...specifically in the nassau area...4 towers around me..its HEAVILY 4g and 3g...3g is lower than 1mb...i actually never reached 1mb.
ever rep said its 'odd' and 'seems wrong'
now i love this phone...the one i have now..no different then the others..and unfortunately im waiting for the one i mailed to reach them ..to switch yet again.
the problem is..idk if i can handle this issue (4g drops to 3g and has to manually move back which takes forever..and very very slow pick up on any of them)
i want to believe this can be solved by a radio update..but judging by the insane amount of tries i have (every type on every version 4.0.1, 4.0.2 and 4.0.3 with kk6..there is no improvement,
im praying its a software..im waiting..and i have a feeling come january 15th...when everyone who has the phone is officially locked in it and loses the worry free exchange..is when verizon or samsung will actually admit whatever problem this is.
what kills me is i left tmobile for this (7+years) all nexus's ,,all unreal connections with free tethering and $65 a month (tax included)...my wife took my plan...and i took hers (she is grandfathered into unlimited data)
Now she has a sgs2...clocking in at 12mbs at home..ON AVERAGE...with fasstt radio switching...mine is unbelievably unstable sometimes can hit that but averages at 6-8. and in this house my wife got amazing connections on her previous 4g phone. very odd stuff, hers to the 4th one being the lucky one!
go figure!

I really wish this phone was more reliable with its signal, and hopefully VZW will get it taken care of. I'm debating about calling in to talk to a tech, but I'm not sure if I even want to because I don't expect anything to be done, and I don't want to swap phones for another one with the same issue. At the same time, I think I'd rather have this phone with some issues over the Rezound or Razr (once you go ICS, you can never go back)

Phone dropping bars (Canada)

Phone is dropping bars like every hour or 2 its really annoying I'm with mobilicity and with ugkL1 baseband. Any recommendation what to do?

What do you mean by "dropping bars"? Phones gain and lose bars depending on signal strength. Unless you mean it's dropping right off the network?

Ya 0 bar and no service and it says like that for hour sometimes till I reboot

Are you a new customer to Mobilicity? If not, what phone did you use with Mobilicity?

Try putting a different SIM card with a different provider and see if the phone is still losing signal.

I too experienced this issue. I am on the TELUS network with a Galaxy Nexus (as of the 20th) and have noticed my data and signal would drop quite often. So I tried doing the System update to 4.0.2 and had the exact same problem with modem KL1. So at this point I tried flashing a Android Revolution ROM and that didn't fix it. Finally, I installed the AOSP Kang Project ROM with Baseband XXKK6 and now I have no problems at all. Data works as it should, and my signal stays in the green almost all day (except for when I'm at home, but that's because I live in a Basement Suite).
Give that a try!

I have the same issue.
And so does the people in this thread:

That's a lot of complaints on that site. Could this be a software issue or bad radio on Samsung's part?

Been thru two phones like this. First one was good for about a day then started playing up. After 3 days it wouldn't connect at all. Sent back for repair, still waiting to get it back but they claim it "should" be fixed with a new ROM - I tried all the available ROMs and radios at the time and none worked for me.
Got another GN while the first was being repaired, lasted 3 weeks and started doing the same thing. This one wasn't rooted, left untouched. It would connect in some places but would drop off the network enough to make the phone unreliable. Sent that one back as well, they're saying its a hardware issue with the internal antenna.
Both were different builds from different places too but the faults behaved the same. I'm waiting to get them both back, will be interesting to see if the software or hardware fix lasts longer... I have no doubt at least one of them will go back again!

Still hoping for a solution to this. Stock galaxy nexus on telus, brand new sim, had this happen. I could literally watch my service go from 5 bars to 0. Go dark grey. then go light grey and slowly creep back up and then go blue again. This process took 15 minutes sometimes. In Calgary, where there should be 0 signal issues.
I've since tried every baseband available, none seemed to solve this.
I've noticed the signal quality in general though is fairly weak. I work in Oil and Gas on remote locations. My coworker has a stock iPhone 4s. His phone consistently gets more bars than mine. I can't even send texts sometimes, and he'll be on the phone talking. I'm jealous.

Verizon Gnex - signal dropping

okay so i've had my verizon gnex for over a month now, and i have tried almost every set of radios on this thing and i cannot for the life of me get a reliable signal.
whenever i reset the phone, it comes up with good signal and 4G every time. but after a while of watching the signal icon, i notice that it stops downloading and will only try uploading. after about 10-20 seconds of that, it flat out drops all signal and goes to no bars with no data. now depending on what radio im trying, it will take between 1 and 10 minutes to regain signal and data again.
I've spend hours and hours searching the web for a fix for this... i've tried different roms, kernels, radios, setting my minimum CPU to 700mhz, etc and have not found a way to get this thing to hold signal 100% of the time. my girlfriend has the rezound and she gets very good signal everywhere we go, and so do i, until it randomly drops then regains it.
It seems like the signal falls asleep then has to reboot or something.
I've read that people with similar issues have exchanged their devices for another gnex through verizon and will get one that works great, while others say they've had 3 or 4 and all of them act the same.
I would exchange this in a heartbeat if i knew the next one i got actually worked, but if it didnt i would hate the fact that i was now stuck with a refurb when i did have a virgin device that worked just as good.
any help would be greatly appreciated.
Thanks in advance!!
P.S. Radios I've Tried:
4.0.1 EK02-LTE EK01-CDMA
4.0.2 EK02-LTE EK05-CDMA
4.0.3 EK04-LTE EK06-CDMA
4.0.4 FA02-LTE FA02-CDMA

Your running Verizon correct???
There are official 4.0.4 radios that I have been using and hand offs and signals are better and faster and more efficient on the battery because it uses the stronger 4G for larger task and would drop to a low 4G speed for energy saving and then shoot up when needed most.
Would you like the radio file???
---------- Post added at 08:24 AM ---------- Previous post was at 08:10 AM ----------
Also it's not the phone or your coverage. It's your sim card. Verizon have just started their sim card program and they admit that it is flawed and should improve as the years go by.
So your sim card is always looking for a 4g signal. But for some reason it is flawed. There I'd a comment about it (read em) that talks about it.

Official 4.0.4 radio?
Which radios do you have? I thought the FC04 / FC05 were the newest and supposed to be the official? If you have newer could you send them to me please.

I would like the radios as well, if possible. I'm currently running 4.0.4 (I was under the impression it was the 'official' Verizon release) which is on I515.10 V.FC04/I515.FC05. Are your radios different? I've heard the 4.0.4 that was released in February has better radios than the one that was released recently, but I haven't checked it out myself.

http://androidcommunity.com/verizon-galaxy-nexus-4-0-4-radios-improve-3g4g-download-20120502/The ones I'm are i515.09 VFC04/ i515.FC05. I think they have different codings or something. Because the one im using gives me 32mbps on maxed 4g bars after I flashed the radios in the link. the one I would get stock from AOKP on Maxed 4G bars 23mbps.
So yeah the ones in the link are better for me. You just gotta do speed tests and experiment for a week or two. I'm satisfied with the radios in the link.
Here's the link:
http://androidcommunity.com/verizon-galaxy-nexus-4-0-4-radios-improve-3g4g-download-20120502/
Remember, they will exactly the same in about phone. They are just coded slightly different I guess of the official Verizon Radios. But I'm pretty sure Verizon will have the radios a little bit different once the OTA is finally released.
(It's a galaxy nexus with a Sense 4 theme. So ignore the sense status bar!)
Here's the picture of my average result.

Get a replacement phone. That type of drop shouldn't be happening.

No don't get a replacement. Had the same data dropping problems.
After I flashed the new radio files in the link, I stopped getting data drops.
It's just the Sim card that could be doing that if it continues after flashing the radios in the link I provided. So get a new sim card. Not the phone.

I went through 4 GN's. The first 3 dropped signal to varying degrees. Radios or a new SIM card didn't fix it. The fourth was finally a keeper and *never* drops. Get a replacement.

I have a new gnex headed my way after going through the same rigamarole as the OP with the radios. The lady at the Verizon store wanted to switch my sim card, I said I wanted a new phone. She has one headed my way, but said to call for a new phone if that one didn't work and to complain to google for making bad software and not releasing the updates (as if google didn't want to push 4.0.4 down). I asked her, "So you're telling me I bought a $ 600 brick?" "Yep."
My phone would drop signal randomly for random periods of time throughout the day since the beginning. I loved my HTC Incredible 2, now I'm kinda sad I broke it.
My issue was signal DROP, not quality, which should not be happening and seems to be a hardware issue.

No. It's all Nexus phones are fine. It's just the radio files. And I haven't suffered any drops since I've flashed the radios.

So i ended up sending it in (reluctantly) and got a new one mailed.
I've had my replacement for about a week now and not 1 dropped call, no data problems, nothing!!
I unlocked, rooted, and flashed AOKP M5, and ugraded to the latest official radios FC04 and FC05.
I am one damn happy customer with my VZW GNEX, its by far the greatest device that I've ever owned.

Hello I have kind of just been lurking on this post and I suffer from the same problem. My first gnex was perfect I never knew anything about data drops until someone stole my original and I got a replacement. Now I'm finding myself flashing a new radio every week. I really hope these 4.0.4. Radios work.

If your phone is like my original, the new radios will not help at all.
I recommend talking to verizon and demand that you have a new phone sent.
Verizon told me that they had no records of this phone having data drop issues, which is a complete load of bullcrap. Just make sure you tell them that you have tried multiple hard resets and that it doesnt do a thing. also, if they bring up the upcoming 4.0.4 update, tell them you just want a new device, as this update will not fix your problem.
Also, make sure to revert to complete stock before you send in your current one.
Good luck.

This was my biggest fear....leaving the iPhone on Sprint and coming to the Galaxy Nexus on Verizon and getting worse signal then Sprint (never thought that possible...lol).
However, I got the GNex on VZW and the signal was 'decent' for Cocoa Beach....but when I rooted and upgraded to 4.04 with the new radios that came along with it, my signal get a lot better. Not had one dropped call or signal since purchase.
Even got decent 4G in Orlando....and 4G is coming to Cocoa this year

i would see what kind of signal other verizon phones are getting in your area. if you both have equally bad signal, i would say its probably just your area. but if you have 1 bar when they have 5, i would get another one.
something to consider is switching to a different phone. i believe (someone correct me if im wrong), that you can switch to a different handset after receiving 3 faulty devices.

I would exchange it still. I got my new phone and it is the way it should be. Went back to AOKP b37 w/ 4.0.4 radios and I couldn't ask for a better phone. No amount of flashing will correct the phone. I told the clerk I had factory reset with the same issues, I think that was what got me the new phone.

Sorry but this is wrong.
My first phone had a faulty radio/antenna. A hardware defect. The replacements I've gotten since have all worked fine on 4G. Same location, same SIM card. Unfortunately the screens are all terrible compared to my first one.
I have tried the new radios on my first phone and it didn't fix a damn thing. Changing SIM cards won't do anything, although Verizon might make you go through that step.
If someone is having the exact problem described in the OP, they need to get a replacement.

I had the exact same problem as the OP and all I did was a complete wipe from my recovery (including dalvik) and flashed the newest CM9 Nightly (06/03/2012). I haven't had a dropped signal since that, and it's been over 12 hours now and I've been on my phone almost non-stop.
Please try a full wipe and re-flash before you get a Verizon Refurbished phone. It worked in my case and it has to work in others.

[CDMA/LTE] Who DOESN'T have signal drop issues?

Ok, so I am on my 4th replacement Galaxy Nexus (CDMA/LTE) All of them are dropping 4G signal every 3 to 5 minutes, but sometimes will go as long as 30 minutes or an hour. Either way, there's WAY too many signal drops. And, for clarification, I don't mean low bars...I mean going from 3 or 4 bars to no connection with the "x".
My original one was I515.09. All of the replacements have been I515.10's. I know the .09 / .10 are the hardware versions (.09 make in Korea and .10 made in China I believe). My wife's does not have the problem (.09 version), my brother in law does not have the problem (.09 version) and the one in my local Verizon store does not have the problem (oddly, a .10 version).
Regardless of what Verizon and Samsung say, this is NOT a coverage issue; it is either a hardware issue or something in the software causing interference with the 4G radios (it doesn't affect 3G signals, only 4G).
The problem seems so prevalent that I decided to do a poll...who among you DO NOT suffer from the signal drop issue? And, if you don't mind, provide a little information if you don't care. I am doing this in hopes of figuring out if this affects all .10 versions (obviously it does not). And if you have a .10 and do not have the issue, I am trying to figure out what combination of roms, kernels, and radios are working for you. I know that none of the variables should affect the signal drop issue, but for some reason some kernels and radio combinations seem to do better than others..
Do you have the issue?
What is your baseband version (.09 / .10)
What rom are you using?
What kernel are you using?
What radios are you using?

Fellow GNex users,
I have been having this same exact problem, too. My original phone was a I515.09, purchased back in early May 2012. Unfortunately, that phone had separate issues with it and I had to send for a replacement. Here I am, two replacements later, and I am experiencing the same issues the OP has. However, with the second phone, I decided to try and isolate the problem, and in an effort to save people some time, I thought I would post what steps I have already taken to try and resolve this issue. The bottom line: I believe it is in fact a hardware-related issue with the newer phones released and/or some firmware issue that is impossible for a user to manipulate.
:::None of these solutions resolved the problem:::
Replaced both the battery and the sim card
Rooted the phone, replacing the bootloader with CWM and installing AOPK milestone-5 on 4.0.4 (full wipe)
Manually installed the latest 4.0.4 Radios (FC04/05)
Installed older Radios (EK04/06)
As for some .10 versions working, it seems there are a few .10's floating out there that have existed at the launch of the product. It must be an older version .10 that does not suffer the same hardware issues that all the new ones have. I have even heard, first-hand, of people purchasing brand new GNex's and experiencing this problem, too. Therefore, I think it extends beyond just a "replacement product" problem.
:::My Solution:::
After talking with a "level two" technician at Verizon who handles dispatching replacement phones, I have requested a notation on my account to send out a baseband version I515.09 (the technician had all .09's at his disposal at the facility, so he was certain there are some in stock, as well.)
I will update this thread after I receive my new replacement, most likely this Friday.
:::UPDATE:::
Just got off the phone with Verizon/Samsung and received some troubling news. According to Verizon, it is basically impossible to know what version they are sending you. As for Samsung, the representative said she is unaware of any problems of this magnitude with the Galaxy Nexus and does not see any updates to correct it in the foreseeable future.
Looks like we are up a creek on this one. It's a sad day, but getting a different phone as a replacement may be the only option we have.
:::FINAL UPDATE:::
Just got off the phone with Samsung. I wanted to call them directly to make sure this issue was reported. After some digging, the representative saw a ticket for a known issue with some versions of the Nexus where an error in the firmware keeps causing the modem to reset, thereby creating the constant dropped signals with 4g. There was no date scheduled for fixing this problem, but he mentioned the ticket saying it would ultimately be resolved by a firmware update over the network.
In the meantime, I did discover that the phone should function properly if you run it in CDMA mode only. I recommend moving to 3g for the time being until a patch can be pushed out to us.

I did but only at my house, where coverage blows. I got a free Airave, problem solved.

I was having this problem a lot when I first got the device and was running the stock 4.0.4 and I'm on the .10 baseband. I tried a couple of the cm10 ROMs and the problem seemed to persist, but then I tried paranoid android and haven't really had an issue since. I found it to be rather odd, but so far so good since this flash.. keeping my fingers crossed that I didn't jinx something.

I am on my second Verizon Galaxy Nexus. So far, 4G has been miserably bad here in Raleigh, NC - including right inside the Crossroads Mall Verizon company store where they swapped me a new one out for my current new one. They did that because I was going on a trip that afternoon and customer service could not get me a replacement phone in time. They checked the old phone's reception in the store and 4G came up, stayed connected for a minute or two, then dropped to an x without even going back to 3G. The salesguy told me he had never seen anything like that before and got me the replacement from stock. He said that 4G reception was perfect at this store, and smiled...
The new phone seemed better at first, but I had to go before I could really check it out. Then I was in a non-4G area during most of the next week and while only 3G was available the data connectivity seemed alright. Things did not look so good though when I got home to Raleigh after that. 4G never stays connected for more than a few minutes here now on this phone either. Locking it down to 3g seems to make it so at least 3g connectivity stays up reliable, but if it is set to Network Mode LTE/CDMA then it will stay briefly in 4G, maybe, and then drop to x and then maybe come back after a while to 3g, which is iffy. Meanwhile my wife's droid3 has a solid 3G connection and my tenant's S3 is solid 4G.
I tried the *#*#4636#*#* menu this afternoon and set the preferred network type to GSM auto (PRL) which is odd because my understanding it that this phone doesn't even have GSM hardware. That sets it into a 4G that seems to maybe stay connected better, maybe because it avoids switching to 3G as easily ?
I guess I will have to get another replacement and hope the new one has a .09 radio instead of the .10 radio like both have had before ?
I am wondering if this is a network type hand-off problem between 3G and 4G or something like that.

I am on .10 and havent had an issue. I got my gnex last month with 4.0.4 installed and it was fine. I then flashed the AOSP JB rom from muzzy and its been working great too. Stock kernels and radios.

In NYC. Rev. 9. No signal dropping issues at all. Completely stock, locked boot loader.

Thanks for all the replies. Looks like there are some good .10 versions out there after all.
Quick update on mine...I'm on replacement #6...or is it #7?...I've lost count. But, I know I still have the issue.
A couple of weird things though...this most recent phone was made in Korea, not China. When I opened it up and saw that I just KNEW I had a .09 version. But, alas, when I turned it on it is indeed .10. I thought all ones made in Korea were .09 and ones made in China were .10, but that doesn't appear to be the case.
And, another weird thing, this new replacement has IMM76Q on it, not 76K. I find that interesting because 76Q hasn't been pushed OTA yet that I am aware of. I actually called Verizon again yesterday and had to go through the same old song and dance with the tech guy and one of the questions he asked me was the build number. When I told him 76Q he informed me that 76Q was not the most recent update and it should be on 76K ( ). I just LOVE knowing more about their devices than they do. I had to inform him that no, 76K is the most recent OTA, but 76Q is actually more recent, just not pushed out yet. He went on to accuse me of rooting my phone (which I haven't yet since it's going back...again) and installing 76Q on it.
I freaking HATE getting "specialists" who do not know what they are talking about. I know more about this phone than they do it seems.

Glad someone brought this back up. I'm about at my wit's end, and am seriously considering their offer to send me a RAZR. Sure I can't hack it, but at least I will have a usable phone.
Just to reduce the repetetiveness I will say I ran whatever kernel came with the ROM I was using at the time. Also, I've not experiemented with the so-called "hybrid" radio sets. All 4 phones always experienced fairly weak signal when compared to my previous phone, an OG Droid. But then again my Droid could send a text message through 3 inches of steel when I was on a ship. My work is a fringe area, so I'm going to focus on the issues I have at home, where I usually get 3-4 bars. Located in Virginia, near Virginia Beach and Norfolk.

Most recent phone (received it yesterday) also came with IMM76Q. Couldn't tell you what the other's came with. I did try turning off 4G about an hour ago, and haven't had a single signal drop since then. <sigh> I totally don't consider this an acceptable solution. Time to call VZW again!

I do not have signal drops.
Except some random 3G drops in the past day or so but I do think it's a result from a dirty flash catching up with me.
Other than that, no issues.
i515.09

I don't have signal drop issues.

I'm on my second Gnex, with no reception issues. My first kept dropping signal at least twice a day. I exchanged it after about a week of having it.

My first one had that issue brand new out of the box. Got it replaced with my current one that works flawlessly. Its a baseband .10

Worst phone yet
I was having similar LTE drops with my Bionic (after I allowed the .905 OTA update). I ended up getting another Bionic and then another SIM. Didn't fix anything. It was obviously the latest build and god knows when the next Motorola update would be, so I got a GNex replacement. That was a mistake. I'm having worse issues with this phone than the Bionic. Can't hold a 4G signal to save my life. Heaven forbid I need to make a phone call, because that's unreliable also. VZW tier 2 tech said it's a known issue and an update is needed to fix it, but the ETA is unknown. She said some of them work and others don't, based on her own personal experience (her sister has a GNex). So I'm getting another Nexus to replace my replacement. We'll see if the next one is any better.
Current Specs:
i515.10 v.FC04/FC05
Stock Kernel 3.0.8-gda6252b
build IMM76Q​

On .09 / LTE and been solid all around for 7 mo's. No matter the rom, version etc.

Rooting issue or just coincidence?

Hey guys, I just a sprint gnex phone a few weeks back and ran the GNex toolkit v9.1 to unlock and root it this past saturday so I could use a hotspot app for my tablet.
I don't know if this is just a bad coincidence or if I did something wrong..I'm not new to roms and have modded my previous phone (evo 4g) about 50 times, but here's what's happening.
Prior to this weekend I had full signal/bars..Now I can barely get 2..It's mostly sitting at 1 bar and sometimes drops the connection entirely. At the same time, every txt msg I send comes back with an error stating it did not send, however...It does actually go through, twice even. This happens with every text to every person.
I didn't put a rom on it, and I didn't even install clockwork mod...I simply just unlocked the bootloader and rooted it. I did setup google voice afterwards. I can't see how doing this would cause these kind of issues and I haven't called Sprint yet as I absolutely despise their customer service..I'd rather get feedback here first.
The coincidence that I'm referring to is that I'm in Austin, Tx and they're in the process of spinning up 4g LTE towers right now..If by chance they started upgrading my tower this weekend (yesterday & today) then I could definitely see these issues...I walked down about 2 blocks where I do get a full 4g signal, but my txting still had the same issue.
Any ideas or thoughts about my problems?

On one hand, I would tell you that rooting doesn't cause that.
On the other hand, you used a toolkit, so who knows what you ended up doing.

If you haven't changed anything as far as ROMs or mods, then I would suspect you're right about something with the network. The only other thing I can think of would be hardware problems of some kind. That seems a lot less likely though. Sprint does supposedly keep a list of networks that are being worked on. You could check in with them and see if the one in your area is being upgraded.

I do know they are upgrading the towers in my zip code to LTE 4G..I'll give em' a call tomorrow and see what they say.
This was the toolkit that I used.

Reboot your phone and go to about and sprint system update.
update profile.
Idk why but its sometimes happens for no reason.
Make sure you have good connection first.(go outside)
If that doesnt work update prl to make the network find the closet tower to you.

I was trying that repeatedly hoping it would fix it..but it doesn't.
On another note, today when I woke up and rebooted the phone I had full bars on 4G signal..Thought life was good and then about 5 mins later it was back to 1 bar 3G. That's the first time I've seen a 4G signal here in my apartment so I'm hoping it really is just the towers in my neighborhood being converted to 4G right now.
I've rebooted my phone 3 times now and the same occurrence happens..Full signal with 4G for a few mins, and then it drops to 1 bar 3G..Have updated my profile and PRL and tried airplane mode..Only way to get that 4G signal back is to reboot the phone..Won't stay on 4G though.
