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)

[Q] How to manually update PRL on LTE G Nexus

Something I'm used to doing with previous smart phones that I haven't been able to do with the G Nexus LTE, is maunally update the PRL. So with that being said does anyone know how to do this or know of a program or app that can do this because I live in a rural area outside of 4g coverage, 3g works just fine, but I figure that me updating the prl would help me get back to full coverage as with my previous 3g smartphones without being in a 4g area, and yes I am aware that 3g and 4g refer to data, but as stated all my previous phones have been 3g phones so that may actually be a small factor. Any knowledge or assistance will be greatly appreciated.

Flash a radio in CWM if you are rooted. LTE phones do not use the *228 update as you have already noticed.. so this is the only way I believe

Thanks and I'll do that if I decide to go ahead and root my phone but I haven't done so yet because this is the first android in a long time that I haven't rooted lol and I know the benefits but the stock rom, to me so far, is better than what im used too, atleast for the moment.

Hmm, there seems to be some disagreement, saving *22899 as a contact and dialing does 'change' the PRL, it isn't clear from the comments I've read that it is updating correctly, although this number does seem to be autodialed by the phone in roaming situations. Some have said this will damage the SIM which I find a bit unlikely. Others have said that rebooting the phone without the SIM (turn off first) then rebooting again with the SIM will, and some say that the PRL is updated every time you reboot... Since I haven't had roaming issues yet, I've not tried any of them...

*228 does damage the SIM.. that's why it's blocked from an LTE phone.

What are you basing this comment on? Speculation? Rumors other people posted online?
The mere fact that many GN users (myself included) have had their phones auto-dial *22899 is pretty clear evidence that it isn't "bad" for your phone. At worst it may be unnecessary as the phones are capable of auto updating, but clearly its not "bad". My phone has been running 52642 for several weeks now and runs very well.

Pull battery, pull sim card, leave out for 90 seconds, re-insert both and reboot. This forces the phone to check/update the PRL.

We had a lot of people do it on Thunderbolt launch day and fry their sims. It was blocked shortly after by Verizon.

As above ^
Otherwise, feel free to dial *228 and tell me why it doesn't work.

Adding *22899 to contacts and dialing out updated my PRL as well. We'll see if it helps with signal out on the farm.

I just tried the *28899 seems to work? Although I'm still not sure how you get a keypad to show up to hit option 2 . But after I added it to contacts and told it to skip activation it programmed. Wish I would of checked my PRL version prior to updating so I'd know if it worked or not.

Works for me

Ok So I know there is alot of Speculation about this..
So I live in an Area where US Cellular and Verizon use each others towers. And my phone used to bounce back and forth between Extended Area (US Cellular) and Verizon.
After doing the *22899 while in a US Cellular area it updated my PRL my Radio reset and I Haven't Bounced back to US Cellular Yet.
I also for whatever reason am Now able to get 4G in our basement of where I work. Before I was lucky to get 3G But Now I get full 3G and when 4G pops up I get 1 Bar.
So I dont know how all this stuff works.. but I went ahead and did the *22899 knowing it could pop my SIM Card (I Used to have a Thunderbolt and Yep It broke the SIM on it when I first got it) But I was prepared to go get another SIM. You never know till you try it, is my Theory.
But Im happy to say, I have Full 4G at my Home. And I have 3G/4G in areas I used to never be able to get it.
BTW- the *22899 from talking to a Guy at the Verizon store said it forces the phone to Update/Activate Even if your in extended area. Thats the difference between *228 and *22899 I tried it out on my Dads old POS phone, its been in extended area since the day I got it for him.. Its just a Cheap Flip Phone. And now he gets 3G.
But yea Id only do this at your own Risk.. I maybe just one of the Lucky ones it works on.. Who knows.

I think as long as you do *22899, it will force the PRL change if there is one. Otherwise it will do it automatically.
*228 does not work though.

Slow data speeds and spotty service

I've noticed spotty and inconsistent data/service on my phone. Even with full bars I get data speeds like shown in the attachments. When using the phone it will sometimes say I have no data connection and ask me to retry. I retry a few times and it finally loads whatever it is I'm loading. I've also noticed that my phone sometimes gets a little warm while in use. I've tried different modems with the same results and I'm about ready to just take it to the sprint store and get it swapped. Any suggestions on what might fix it? I can confirm that it is something with my phone because I've run side by side speed tests with my friends OG epic and their speeds are normal. Any help would be greatly appreciated.

Thats about what I get too. Its a combo of this phone and Sprints crappy network! My evo got better speeds as well.

I am getting the same thing too. Funny thing is that it just started being this way recently, it wasn't always slow. It is not just the data speeds, I am getting no service in places where I used to get service.
I have been seriously thinking about switching carriers and moving to t-mobile but a little afraid because I have been with sprint forever.
If something don't change by the end of the month, sprint may be losing another customer since the GSIII is on ALL carriers.
I am in Raleigh/Durham NC by the way.

I agree... it didn't feel so bad until I got my ET4G, but I just figured it was a network issue. I'm trying the EL29 modem on my Calks 1.6 now. If anything I'll try going fully stock and see if that helps.

Welcome to the Sprint network

Some people are experiencing network issues in places where Sprint is upgrading to LTE. I don't know how far-reaching the effects are but could possibly have something to do with it.

lol wtf

Yes, I notice the same thing lately with Sprint Wimax, I may have to dumb Sprint later. Sprint data speed gradually slows down from time to time, some area, Sprint shows only 1X, I look at friends' phones with Verizon, ATT and Tmobile, they have very good speed. My brother has Verizon LTE phone, I speedtested at the same location, he got like 17mbps download and upload is about 15mbps, mine is 1X speed. Suck, I gonna say goodbye to Sprint later.

Welcome to the Sprint network with the New iPhone4s d-bags. Seems like things were great till they showed up. Even my Evo got slower.

data
Maybe your phone is stuck in 1x..
What i do is i go into debug (##debug# in dialer) and i go to others, and then i select hdr/1x and i click on evdo mode. Try doing this but you need your msl.
Caution: ive tried it on ics roms and its really weird. Try going on a GB rom and do that. Oh and on EVDO, you wont be able to recieve messages, so when you are done change the setting back to hybrid.

NC market has some EVDO issues affecting certain users.
I was just told this after getting off the phone with them earlier today for a different issue.

Still incredibly slow, but I'm hoping the network update fixes some things. Thanks for the information though!

Error 34 Network issues

I've can only send texts periodically. But most of the time I get Error code 34
When I'm roaming on Verizon (in Austin, Tx) I have no problem ever sending texts, but when I'm on the sprint network most of the time doesn't work. I haven't been able to narrow down when it's exactly happening.
Here are the details when I'm in the zip code 78759
1. Shows 5 bars of service. I have ran ##Debug# and can see that I'm on PN 80
2. I attempt to send text.
3. While the text is pending, the service slowly goes down to 0 and fails with error code 34,
4. It comes back in roaming. (the time stamp is much later because I had turned roaming off during the test. I had to go back in and enable it). I dial *99 and it tells me that I'm on the Verizon Network.
5. I resend the text and it's works fine.
I have a thread over on sprint's forum. It's the first google link when you search for error code 34, I'm DanT0007
I have factory reset the phone 6 times (every time I've spoken with a Sprint Rep) and replaced the entire phone once.
When my phone is sitting 2 inches from another Sprint Samsung Galaxy S3, mine shows itself going in and out of roaming, whereas his stays stead at 5 bars and he can send text's just fine. We compare PN's in ##debug# and he is on PN 80 the whole time. I go from PN 80 to roaming and fail to send the text.
This has been going on since I purchased the SGS3, 6 months ago. Previously I had the SGS1 and I no problems with it whatsoever (beyond known issues with the gps)
The problem seems to get worse when I'm indoors. When I'm outdoors, I can get amazing reception. Sprint says that they don't guarantee their phones for indoor use, but it doesn't seem to matter how thick the walls are. If I'm inside, I get crappy signal.
Are there more troubleshooting steps I can perform? Has anyone else seen this issue?

Hmm, not guaranteeing anything, but you can try forcing hands-free activation (make sure you're connected to wifi).
Go to the dialer and put in ##72786#. Then wait for you device to be reconfigured and check whether there are still issues.
If that does NOT, it's likely to be a hardware problem. I have 3 Sprint S3s in my housr and all of them get practically the same reception whether inside or out (comparing dbM).

check to see if they are working on the towers nearby, if they are part of Network Vision, or having capacity upgrades. I consistently have the same issue with my GS3, and had the same issue with my iPhone 4s in the same area because they have been working on our tower here.

I tried that and it seemed to work for about 3 or 4 texts, but I think that was probably just conicidence. Like I said, it sometimes will work.

I have talked to 5 Sprint rep's and one of them said they have been working on the tower in my area for 6 months (which is how long this has been happening) all other reps say that's not true. I think she just wanted to get me off the line. Which is ok, since she didn't sound very intelligent anyway.

Is there anyway to quickly transfer service between the two SGS3s? or would I have to call in to sprint?
I also still have my old samsung galaxy s1, would I have to call in to sprint to transfer service back and forth?

Have you checked to make sure your mobile networks is set to LTE / CDMA ? Have you checked if your Roaming network is set to Automatic, instead of Sprint only ? Have you checked the Roaming Guard settings ? Also the Roaming settings ?
To answer your question, you can transfer service between devices online. But I always call Sprint, just in case they have to do something else on their end.

LTE/CDMA - Yes
Roaming - Automatic
Roaming Guard Off
I should reiterate that when I'm roaming (on verizon) it ALWAYS works. Since this is the case, I find it very hard to believe that it is a problem with my phone.
I should also say that it never seems to work on PN 80. Sometimes I'll try to send a text on PN 80, it'll go from 5 bars to 0 bars, then come jump to another tower (like 242) and it will then work just fine.
So, you'd think that tower 80 is the problem...but I have checked with two other people in the same building as me, with sprint service and samsung galaxy s3's and they can send texts just fine on tower 80.
It's almost like my phone is being denied from connecting to tower 80. I will try switching my phone back to my old one tonight or tomorrow.

When you called Sprint, did you have them reset the Data on your Device ? If not you may want to give that a try.

They told me they completely removed me and re-added me from their system. I assume this "reset" everything, but if that's an incorrect assumption, I can call back.

Yes that would reset everything. The strange thing is doing a complete data reset like that on their end, should have resolced the issue. Did they check to make sure your account has no limitations? You said you already returned one device. Why was that?

The rep said there are no limitations. I returned the original device for this same issue.
I just called sprint and had them revert the service to my old phone, the samsung Epic, which worked fine for 2.5 years. Now that one fails to send texts 50% of the time. I never had problems before.
Yet still, the technicians conclusion was that it is a problem with my Galaxy S3.
When I force a PRL that uses verizon's towers, I have never had a text message fail to send. It seems to me that it's a problem with my account.

I think I figured it out. I work in a tech company that does RF stuff. There is a small radius around a particular device that must be communicating on the same frequency of the tower I'm trying to connect to. The phone must go into some kind of mode where it keeps jumping from towers, so when I go to my friends area (50 ft away) my phone is still jumping from tower to tower. So it still fails, whereas his succeeds.
Today, I had him bring his phone over to my area, and sure enough, it failed when he was connected to tower 80. I'll try to update as I know more.

That's very interesting. Please keep us posted as to if that was definitely the issue.

Have you tried using APN Backup and Restore and reconfiguring your APN to be used on all towers?
I've had messaging problems on my E4GT and now with the new apn.xml i installed
I can do both messaging and MMS on either TW JB or AOSP.

[Q] Data service iffy on LTE - phone or Straight Talk issue

Hi,
I've been having data issues with my HTC ONE M8 on Straight Talk for the past couple of weeks. the data service for some reasons got really iffy. before everything was absolutely fine. now sometimes I cannot access data at all, sometimes something is working and something doesn't.
when the data doesn't work:
- most of websites are not reachable
- google.com seems to work normally
- google maps might work; sometimes very slow, sometimes not working at all
- ookla speedtest won't start, but if I set a fixed server it might work
- facebook.com might work in the browser but the app doesn't work
- refreshing the page seems to help
on WI-FI I have absolutely no problem. everything works fine.
phone and txt messages work without problems.
on 3G (HSDPA) everything seems to work fine. I see problems when on LTE.
anybody has the similar issues?? any suggestions?
many thank!!

I am having the exact same issue! So frustrating, I don't want to use 3g if we should be on "Full speed 4G LTE for up to 3GB"!
tried so many different APN's, no luck can't get over 2.5mbps with any of them

I would be happy with anything that works right now. the service is just NOT WORKING. I am paying for a service that doesn't work and that's not acceptable.
I opened a case with the help desk; useless. I was talking to people who don't understand the basic concepts of networking. made me add a proxy to the APN; no difference at all.
then I put a complain on Twitter and got some other people "helping" via email. at least they asked for the address of where I am always having problems; hopefully, they check out the service at the antenna. I think it's not a BTS (antenna) issue but something related to their proxy, firewall or network gateway since google.com works without problems!
I talked to a friend of mine who has StraightTalk as well and he said that he had the same issue last year!

I had the exact same issue with Net10 it is so annoying and unacceptable =(

Have you tried calling straight talk a call

U can try this from what I know ur phone gets chooses the strongest signal tower example u are around 3G tower it has a 9/10 signal and the 4g tower is a 6/10 strength it goes with the 3g hope this helps in ur dial pad dial *#*#4636#*#* then Phone Information....Scroll down a little bit to Set preferred network type. I was able to lock in LTE only doing this and gave me the fastest signal on my device hope with works for u. If u can post ur original settings before u change to lte option only on this post so u can always revert to ur original setting good luck.

U can try this from what I know ur phone gets chooses the strongest signal tower example u are around 3G tower it has a 9/10 signal and the 4g tower is a 6/10 strength it goes with the 3g hope this helps in ur dial pad dial *#*#4636#*#* then Phone Information....Scroll down a little bit to Set preferred network type. I was able to lock in LTE only doing this and gave me the fastest signal on my device hope with works for u.

if I lock it to 3G it actually works well. I will try your suggested settings.
on another note I wonder if it's an issue with the phone radio implementation. my Nokia/Windows phone sees LTE very very slow but it doesn't stop working completely.

Hmmm Idk but anything's worth a try what settings do u have it on already?

if I put it on GSM/WCDMA (so no LTE) data works fine in 3G.
and if I do a speed test in 3G it gets about 5Mbps in download vs 1, 2 or 3 Mbps when LTE works (ZERO otherwise)

The exact same thing started happening to me two or three weeks ago. More often than not, the LTE connection simply doesn't work, and when it does, it's excruciatingly slow (anywhere from 0.01 to 2.50 mpbs, and usually less than 1.00). Do you guys have AT&T or T-Mo sims? I'm starting to wonder if going to Cricket would solve the problem, but since I'm running an AT&T sim, I'm not sure if anything would change since it's on the same network.
Straight Talk support is worthless... they think a factory data reset will fix it, when it's clearly a network issue. I just told them to stop right there and started troubleshooting myself. That's a good tip about dialing *#*#4636#*#* and turning off LTE that way. It seems like that is where the issue lies - I'm having good luck with HSPA; it's slower than LTE should be, but at least it works. It'll do as a stopgap through the end of my billing cycle, at which point I can decide whether to go somewhere else or get by on HSPA until they fix whatever the problem is.

tried and on pure LTE it simply doesn't work. the only way is to set GSM/WCDMA and it goes at 3G speeds but at least it works.
the funny part is that Google.com always works, whatsapp works, googleplay works. so it seems a problem with throttling or filtering to me.

yes. completely incompetent. asked for a supervisor; no way to speak to one.
I posted on Twitter and ST got back to me asking to send them an email. I did. 10 different people sending me emails with conflicting actions.
insanely frustrating.

I have ST on AT&T.
a friend of mine with iPhone 6 down in Newport has no problems. he sent me screenshots of speed test at 15Mbps.
I really wonder if it's some radio firmware issue...

Ironically, I ran into something very like this too recently....I was on an at&t straighttalk sim...lte had been OK prior to me updating to 4.4.4. It was never spectacular, but it was, at least, lte speeds. After the update I noticed it had become really sketchy...just as described, pretty much; even when mine worked it was trash. 3g was much better and totally stable. I thought it might be the update, but long story short, it wasn't. I inserted a friend's sim from tmobile and got full lte with no issues.
Now, in my case, I had been using a shaved down microsim rather than a nano sim, so I thought, maybe that's the issue. I noticed when ordering the new one, the tmobile one actually said htc m8 compatible on the page(plus my friend's legit tmobile sim got good signal and lte so I thought that's a good basis for comparison). Got the new one, put my number on it, and voila! I'm getting on average 20mbps lte. And it's very consistent too. So now I'm on the tmobile straighttalk sim and everything is fine.
Anyways, it's only $7 with free overnight shipping, so that's something easy to try. This wouldn't be the first time a new sim fixed all sorts of weird data problems with straighttalk either. I've been on with them for several years now and this is probably my 4-5th sim I've had to get for various reasons.
So, anyways, your mileage may vary but that fixed it for me. Hope it helps.

it seems ST on T-mobile is not having the same issues as ST on AT&T. the problem is that T-mobile coverage is not so good in my area.
I tried my phone in a different location (400 miles away) and had the same issues.

I've done some more testing.
it is really weird that Google.com works flawless while any other site seems not to work.
activating "save data usage" in Chrome seems to help. however it doesn't solve the problem. sometimes pages needs to be reloaded a few times.
even when LTE works, the OOKLA speed test gives me 2Mbps in dowload and 5-6Mbps in upload. so no matter what, I am better off with 3G.

I found an interesting thread here on XDA. I am not rooted at the moment and can't try.
<<
If you are rooted there is simple FIX, simple disable FD8 (Fast dormacy 8)
ro.ril.enable.r8fd=1
ro.ril.enable.pre_r8fd=1
Change both to =0 and issue will be fixed.
If your not rooted only fix is to keep HotSpot enabled than data connection wont break.

I tried the hotspot trick but it doesn't work for me

Sorry to bump an old thread, but I just wanted to give a brief update. My LTE issues with Straight Talk went unresolved for about 6 weeks despite multiple conversations with customer service. I experienced this in Raleigh, NC, Greensboro, NC, and Virginia Beach, VA. Then for Thanksgiving, I went to New York City and New Jersey (the part just outside of Philly), where all data connections were unreliable. Yes, that means 2G, 3G, HSPA, and LTE were all spotty at best the entire time.
I ran out of patience after that, and since my billing cycle was ending on 12/4, I switched to Cricket when I got home. As soon as I popped in the Cricket sim card, everything started working flawlessly again. Cricket does limit you to 8 mbps down, but that's good enough for my purposes. The issue, if it's still going on, is with Straight Talk and not the phone.

Lollipop Fixed the Issue on my HTC M8
Hey all,
I've been following this thread as I too had issues with LTE on my HTC M8 using StraightTalk. When I first got my phone, it worked perfectly with LTE on ST. Then I ran the OS update that was released sometime near November. That's when I noticed the problems. I could run a search on Google but any webpage I would try to connect to would not load. The phone would hang and eventually time out. Your instructions to turn off LTE was great help. Pages load perfectly provided LTE is not used. I was getting really frustrated and you kept me from throwing my phone at a wall. Thanks for that.
So that brings me to this post. I updated my phone to Lollipop this morning. Thought I'd give turning LTE back on and bam.... works perfectly. I've been testing it all morning and so far, all pages load really fast. I will keep an eye on it for a while and post any updates but thought I pay it back a bit with the good news since you guys helped me.
Thanks again.
AC

thank you for sharing!!
trying to upgrade to Lollipop. unfortunately I am having an issue with the recovery (flashed from TWRP to a stock that doesn't work with the OTA and can't flash any other recovery -not sure what's wrong).
when I solve this issue and able to upgrade to Lollipop I will share my LTE test results
