AT&T G2 LTE signal problem? - AT&T LG G2

Hey all,
I recently picked up a LG G2 (second hand)
and I believe I have some issues with the phone not picking up LTE so easily.
Before this, I had Iphone 5, nexus 4, G Pro, Gnote2, etc... and they all picked up LTE just fine at my home
However, G2 rarely picks up LTE signal and it is mostly on HSPA+ (4G Icon) I believe.
I took it into AT&T store to see if I could get a new sim card but when I got there, the phone picked up LTE no problem.........
Looks like many Sprint users are experiencing same issue.. is there a fix for this??
*The phone is currently on stock / non-rooted 4.4.2
Thank you in advance!

I'm in the same boat as you, my data will work for a good 30+ min and then all of sudden no network for 30 seconds or so. I've also been unable to connect to a lte signal I've only been able to use hspa, searching the threads on here have been hit and miss with a lot of vague answers but nothing clear cut if anyone's dealt with this and has a clear fix it would be appreciated.

A little update to this, yesterday I went to AT&T to see if I could maybe clear this up with a new SIM card and while waiting I checked out the two G2s they had there, these two display phones were literally 10 ft apart and one had lte while the other one was stuck on 4g only. I think this is looking more like a hardware issue now after checking out both store phones on display, I'm going in today to swap out my handset to see if this will solve it.

Here's another update for those with lte or signal loss issues, after trying everything I could find on these forums the only answer was a warranty swap out, as soon as I put my SIM card into the warranty phone let showed up and after half a day I haven't experienced no random signal loss at all.

Interesting...
This is interesting. Currently running CM11 latest nightly and I thought it was due to CM codebase. It looks like non-CM related?
Please keep the details coming. When I have time, I will flash a stock ROM to see what happens. But at this point, it looks scary that maybe hardware problems might be there.
For comparison, 2 iPhones literally next to G2 had 3 bars with LTE while my G2 had no network.

After a full day and a half use now im fulling supporting the theory of a hardware fault. Before returning my phone for a replacement i was fully rooted on gardys kit kat rom with recovery, i had read that supposedly rooting or flashing was apparently breaking lte so i went back to the stock jellybean rom only to discover the issue still there, i then fully updated to the over the air kit kat update which also did not solve the issue. It really does look like theres a issue with the phone itself.

Oh wow. Thanks for your reply.
So i have tried working on this and so far no good.
LTE picks up good when i walk into an att store and that is causing difficulty with store workers..
I get stable, steady connection with hspa+ but rarely pick up LTE..
What is the process of getting a replacement? Its way over 15,30 day period for me..

For me lte did not work at all even in store, I can see where you might have a issue if they can't reproduce the issue but just be persistent and they should take care of it for you. As for warranty you have a year from your purchase date for a warranty claim through At&t, I went through a device support center which you might have depending on where you live otherwise you can send it in. You must revert back to a complete stock state or you will be more than likely denied.

Got it fixed after several attempts with new sim cards! Picks up Lte fine! Wootwoot

My fix
call att tech support make sure that the lg g2 imei matches your line/sim card
So I went through a bunch of phones in the past couple weeks, I have at&t service but my last phone was verizon droid maxx. Next I went to the AT&T store and he put my phone number under the new sim card for my AT&T LG G2 but the rep didn't ask me for the IMEI or look at the phone at all, he just got my line on the new sim and I left. I noticed the phone was going back and fourth to LTE but it was 4g (non LTE) about 70% of the time. I changed APN settings, I updated, nothing worked. Then I remembered a long time ago that if you go from android, blackberry, or iphone to another type of phone you would have to call att and make sure something was changed so I called att tech support and asked if they would put my IMEI under the new sim, the tech said yeah I should do that because currently my line doesn't show I have the g2 (make sure to call tech support because online it'll show you have a g2 and if you call costumer service usually they will see the g2 too) and after that i reset my phone and got LTE 100% of the time since then.

[Q] G2X 4G Problems

I've had this phone since release and have loved it. I have only one issue with it. I'll be trying to use my internet on the phone and it will show the upload arrow but the download will never do anything. I have full signal so this is not the problem. This happends a lot and in the middle of browsing it will do it... It will load a page and I'll click a link and it wont load and then it will work again after awhile. Does anyone else have this problem? Does anyone know a fix or the reason its doing this. Also I have full 4G coverage where I am.
It happens to me a lot too! Its very inconvenient and I know its not the area where I reside because I also have a g2 on my spare line and the g2s data works perfectly fine when the g2xs is stalling. :/

Did you get yours at release? If so it may just be the first batch or something...
Could be lots of things. Have you activated and are using the SIM that came with the phone. Supposedly the G2x uses a new SIM format.
What OS are you running? Are you on WiFi? 2G, 3G, 4G? Where does this occur?
I surf my with my phone a lot and I don't get that intermittent data problem you are describing. I am running the latest CM7 (#70) and in a 3G area with average signal quality.
I'm using the SIM that came with the phone and this is only on 4G I reverted back to stock ROM unrooted and still has the problem
I've never rooted my phone. I've actually swapped the sim twice already thinking it was the problem. Hard reset has been done. I've pretty much tried every trick in the book and the problem still persists. Its my 2nd replacement(1st one had the same issue)

P.s I got the first one at release then had it exchanged(buyers remorse period) for a new one towards the end of may so I doubt the 2nd one was from the first batch.

Like Player said, could be alot of things. For a sim, the G2x does not require a brand new sim, but it does require a newer sim. If your sim is older than 18 months, put in the one that came with the phone. Last years TMOBILE sim will work with the G2x.
Also, data plan. Didn't happen to me, but did happen to my son, the plan was not enabled for 4g Android. He got signal, rarely 4g...but did get 2g.3g. Walked back in the store..asked what was up...they checked...1 mouse click and finished. Funny thing was, he bought the phone from them, earlier in the day. You would have thought they would have covered that.

Your sons phone was showing 3g? Hmm... I thought on tmo 4g was a fast version of 3g and that the g2x only showed 2g or 4g. I am probably misunderstanding something.
So I went to T-Mobile just now and they gave me a new SIM and it fixed all the problems so if anyone else is having trouble try getting a new SIM first....its free

So frustrated, about to return One X but seeking advice

All,
I have had the One X for just over a week now. Three times, I have had to hard reset the phone because it stops receiving / making calls, and data stops.
I tried searching the forums but it seems like issues are all over the board and couldn't really find something that was exactly my issue. If there is one, I apologize for the duplicate post.
Regardless, when the phone is in this state, it appears like everything is working. It shows I have great signal, the little 4G icon is there, indicating that everything is working.
Anyone else have this problem or could I possibly just have a bad unit? AT&T already swapped out the SIM card thinking that might fix it, but no luck.

I think you should swap out the phone as bad before returning it if that's the only issue you're having. mine seems flawless in that regard. I haven't missed or dropped a single call.

I don't recall ever having that problem. Mine was pretty random too, in fact it got so bad yesterday that I missed several important calls.
If I would restart the phone, I would get all my missed text messages and the voicemail (google voice) would tell me I have messages waiting..
Very frustrating.

I thought that might be my problem too, but where I could stand in one place and have the problem, restart the phone, and then not have the problem -- that leads me to believe there was something wrong with the phone.

Nope the wife's inspire stayed on hspa
My X started out ok, but these last couple of days I have NO signal anywhere. Also SMS/MMS is barely working. (and when it does, people are getting multiples) And its dropping pretty much every single call.
I just called my corp store, they have plenty in stock. I'm going to go exchange it. Should I ask for a new SIM also?
And my screen is perfect, here's hoping I get another good one...

However, AT&T's LTE phones are notorious for connection problems on non-LTE market. These LTE phones use a new APN called pta. I just had the same problem while traveling through PA yesterday. Lost data connections many times and had to reboot the phone at the end of the day to regain data connection of any kind.
So, it is AT&T's service and also the phone firmware that can't properly handle the fact that it can't receive any LTE signal in certain areas.

return it and get another phone, besides the One X, it's all hype anyway. The HTC vivid is a much more solid phone.
I had almost the same issue. My device was on wifi and would at random times just stop pulling data. Or at time just not make calls. I tried trouble shooting it but I was basically told since I didn't have it long I should get it replaced. I replaced it and the new device is perfect. I have not once had that issue again.

Who said I'm going to reture it. OneX, regardless all its problems is still way better than any alternatives AT&T have. There is no such thing as problem free Android phones. I've being many of them. They all have problems one way or another. Vivid with its ancient S3 CPU and SD screen just plain sucked. My SGS2 can kick its butt.
For me the form factor of One X, LTE speed, S4 processor and HD screen are the main things I pick One X over any other phones available on AT&T. These software bugs will be corrected overtime.
I just came back from my store. They had plenty in stock but said when that runs out, they have no idea when they will see anymore.
I have a brand new 1X, and a new SIM card. Hopefully this one works.
I stopped by a vzw store to look at the gnex and my hox side by side. I've decided to keep the HOX. Screen on the gnex was way too bright and I ran quadrant side by side on both phones. The hox blew the gnex out of the water.

Bought mine yesterday and this same issue happened to me today. Had full reception on 4G but could not send a text or place a call. Happened twice today, and I dont know if I want to return it ASAP or if its software related and may be fixed.
I had that problem 3 days after buying the phone. Data, calls, texts..tons of problems. Phone was unusable half the time. I went and exchanged it for another one. I am now at 6 days with the new phone. No problems. I hope it lasts.

potential signal problem

Hey everyone, i'm a new coming from the OG razr and while i heard the radio on the s3 isn't as good as the razr i think my phone might have a problem. It seems to get stuck on 1x a lot and the only way to get back to 4g is to restart the phone. my phone is rooted but stock rom. Is this a common problem? Also under under APN LTE verizon internet is checked not EHRPD. Is this correct?

Its not normal. Take it back before your 14 day period and they'll give you a brand new one for it. If you wait then you'll just get a refurb.

is unrooting as easy as rooting? I'm hoping theres a script or program that can unroot as I'm not the most tech savvy. I'm guessing if i'm bringing it back i'll need to unroot.

Yeah it's true, put simply. You can see if it's the sim. But like I said, if you try to get a replacement after your return period, then you'll just get a refurb. So be quick on the draw if the sim card doesn't fix it.

S3s are known to have a number of data issues. Call technical support and try their ideas. When you can rule everything else out, then you know it's your phone. Basically, if a new sim or a factory reset doesn't fix it, you need a new phone.

I took my phone in the store yesterday and they told me flat out that I sim card won't do anything for your signal. I'm not discounting what you're saying, just telling you guys what they told me.
My signal is garbage at home AND at work. I use wifi at home to play with the phone but actual 3G signal is bad. I am lucky to get 2 bars but its generally 1 with speed tests of about 80kbps.
I don't have WIFI at work, and get no signal at all.
I still have a week to return the phone but I'd like to keep it if I can get a better signal.
I am still within my 14 day, maybe 5 days left

Are you new to VZW or have all of your phones had the same problem?
With the thought of you possibly leaving VZW, you would think the store would have tried a new sim card, if only to pacify you. Or they might have offered to switch out the device.

I have been with Verizon for years. My Droid X didn't have the best signal but it was much better than this.
One problem is, the store is located in a 4G area, it works great there but it doesn't where I live, nor where I work (which is a decent sized city)
It sounds like you have a bad phone. I'd be pushing for a new one before your worry-free period is up.
Okay, I reset my phone this morning and surprisingly, the signal is much better.
I went from 80-100kbps to about 500-600 kbps. Does that even make sense? The phone is only a week old
Now, perhaps I'm getting too hopeful here and the wind is blowing the right way today or something.
Yesterday I checked my signal with 'Open Signal' (I'd love to know of a good tower location app), and my signal was about 20-23%, right now its at 32-37%. I know that isn't a great jump but in the scheme of things, it is. I'm also at -97dBm, I think yesterday and the day before was over 100
I will note however that I'm still at 2 bars of 3G
I think its just chance , but I'll keep an eye on it.
Couple of weeks ago I also contacted VZW about bad signal/slow data speeds with my phone. They also told me a SIM would be the first fix to try. I had them send me one, for free 2nd day.
Before I swapped it out.. I rebooted my phone and put it in a certain spot and observed signal strength. In my house it ranges from -109 to -113. The data speeds, when the test would even finish, were abysmal. Ran 3 tests and in general they were about 500Kb/s down and anywhere from 0 to 300Kb/s Up. And that was on LTE!
Now without wiping my phone or anything I installed the new SIM and called VZW to activate as their website was bombing. Finally got the thing activated then put my phone back in the same exact spot to observe any changes. While signal strength did not get any better my data speeds increased a whole lot! In the same spot I was getting 5 Mb/s Down and 3 Mb/s Up on average.
Ive also noticed a decrease in LTE drops to 3G and 1X like I was getting before.
So while Ill say that it would seem to be impossible for a SIM to make your signal better, it just may help with your connection.
Thanks for that, I'm going to go up there in awhile and at least swap the card
Well this is my side of the story I had the Galaxy Nexus before sometimes in New York I am in spots where I dont have 4G what is weaird when I go into someones house which i've been many times I only get 3G and then when I go outside I get LTE anyways at the same spot I get 1-2 3G bars and my friend gets 3 bars on iPhone 4S but when doing speed test on both it seems about the same.
Also I am running CM10 and when I was on stock I could tell the signal was a little bit better , you guys think it would be worth a try to swap out sim card as well? how do I make them give me a swap for free?

4G Data Drops

I finally got someone at Verizon to admit that the 4G dropping issue is at the top of the known issue list. Each time I have gone in the store I have been met with 'surprise' that this is an issue. Invariably they have tried to replace my SIM card or phone none of which has worked. The notes on this issue that the phone support person had were rather disturbing.
The first one indicated that this was a known, accepted issue and that the phone was working as intended. Ack!
The second note said that the vendor was working on the issue...IE HTC.
So...onto HTC I go...
The HTC rep also admitted knowing about the problem. He said they were working on a software update to correct this. This of course led to discussion about ICS. According to the HTC rep I spoke with the update has NOT officially been cancelled at this point. He could not say whether or not the fix for the 4G drops they were working involved ICS, but did seem to indicate it might. As usual no remote ETA as to the fix.
Truthfully I could care less about ICS...I would just to have dependable 4G that didn't drop every time I try to use GPS to get home from work, stream music for my kids, or check Facebook.

I just got a new sim and so far so good. What rom and radio are you on? Radio's tend to be a big factor in data dropping.

Yeah if I run twisted build my 4g will drop but if I use let's say skyraider I have no data drops where ever I go. Many times you need to find the right radio for the rom you use.

Well...I have tried the .19, the .9 and the leaked ICS radios when I tried the ICS builds. I actually don't know about the leaked radios as I had too many other issues with ICS at this point for me to use regularly...but the .9 and the .19 both give me pretty regular 4G drops. I just dropped back to the .3 radio this morning to see if that helps.
Thanks for chiming in. Maybe I should try another SIM card...only replaced that once...have replaced the phone 3 times now. I spoke with Verizon AGAIN yesterday and was basically told what did I expect with a two year old phone. I guess they expect you to have to buy a new phone every two years to keep them working. Freaking consumer society.
A level 2 tech told me that the drops are also related to the fact that the 4g network isn't fully implemented. What we get most the time is a 4g extension that was put in place to expand the network faster. They also told me that the parts of the network that are a 4g extension get only half the speed of a fully implemented area. The suggestion I was given was just disable 4g when I'm in areas that have spotty coverage which actually helps. The problem seems to show itself on the hand off between 3g and 4g. Almost like the phone gets confused on which network it should be on.

I think I am in a crappy 4g zone. But now you make me wonder about that...
I'm in an area with solid 4G coverage (I use an LG Revolution). I just installed a ROM on my brother's Thunderbolt for the first time last night, largely prompted by his phone being stuck on 1X regardless of where he is. Sadly, it didn't seem to help, even with trying to flash a few radios. His friend also has a Thunderbolt, and his has no connection problems in the same area. Who knows.

Calls made when on LTE keep getting dropped

About 3 out of 5 times when I make a call when I am originally on LTE the phone call drops. I am on AT&T and when I make a call it switches from LTE to H+ then all of a sudden it just completely drops signal and thus the call and about 3 seconds later regains signal. Does anyone know what may be causing this issue or has had this issue? I am on 4.4.4 Stock with Root.
Well dropping calls isn't normal, but dropping from LTE to H+ is. VoLTE isn't really a thing yet. Calls don't work over LTE, so when you make a call it automatically drops to H+. That's normal behavior.
Did this just start happening out of the blue? Or always done that? Make sure you have the correct APN settings. If so try calling your provider and see if there's anything they can do for you.

Sorry forget to mention I knew that was normal for the drop to H+, but yes the signal drop is not. Well it started out of the blue. IS there a thread on here with what should be the correct APN settings? Also my old nexus 5 started to do this before I returned it under warranty for refurbished, then I had a moto G lte for a month worked fine, got a refurbished (due to warranty) and started again.
Here is a graph of my network coverage to show that the signal just drops.

Mine doesn't seem to have any particular count pattern, it happens very randomly, usually when attempting to call someone and once they pickup on their end, my phone would hang up. This happens maybe 40-50%of the time, can't estimate a guess, but i can say that it happens enough to piss me off. I've checked my AT&T APN, which matches to what the carrier has it set, i even went and got my SIM replaced, rebooted in safe mode, gps works, so it's not a third party app causing this. Last resort is factory reset, although I'm almost positive that won't do anything. I'm currently also running android 4.4.4 stock aosp on a 32Gb N5. Device was purchased new in early may 2014, and came with android 4.4.2 preinstalled. The random call drops issue started in early October, a few months well into 4.4.4 update. All I've found online is that i it has something to do with a missing cellular radio, but to be honest, i don't want to mess with those as that may cause further problems. Called Google, and they act like they're clueless about this issue, all they can offer is a replacement, which is nice, but to be honest, it's probably going to happen again even with the new device. My coworker has the same issue with his 16gb N5 black model. If anyone with this device trying out android 5.0 lollipop preview can chime in on if this problem still persists, would be very awesome. I'm going to wait and see when the official android 5.0 comes out, if that fixes the dropped calls problem, then N5 can be used, if not then I'm getting it replaced and reselling it, may go with the moto x+1. So either a good portion of nexus 5 devices are factory defects or this really is a cellular radio problem. Really hope that lollipop will fix this issue.
The APN only handles packet data and not voice so that shouldn't be the issue.
I would try setting your phone to 3G only for a while and see if the drops still occur when you are on 3G prior to the call.

Yea it wasn't an exact count but like 3 out of 5 says, enough that is annoys me. Tried all those as well and like I said I have a moto g lte that the sim worked in so it isn't the sim. This is my refurb unit, but the other one I have since November started to do the same thing in August as well on 4.4.4 never had an issue before that. Where did you find that if you don't mind me asking? I am comfy enough to mess with that stuff, so i'll give it a shot.

Already did and it doesn't but is an annoyance then since part of the price of the Nexus 5 is to have LTE and I am not getting the full product then which is not ideal.

I found it here (just take away the spaces after .com and after 02/): ianmarmour.com /2014/02/02/ google-nexus-5-fixing-modemcellular-issues-on-34g-networks
It's an older post from February, but seems to have the best details and fixes. If you simply search nexus 5 cellular radio issues or nexus 5 4.4.4 call drops, you should find a lot of these recalls from lots of N5 users. I'm tempted to try it, but don't really feel like sorting all my files in case i brick my device. I'm also not sure if ota update will work if i tinker with cell radios. Otherwise that's the page containing all the details you'd need including links and step by step guides. And hey if it works for you, let me know, maybe I'll try it out if it goes well for you.

Exactly, i know that's totally possible, but i wouldn't want a smartphone that has no lte and/or hspa+ service at this point in time. This seems to happen wherever lte isn't as strong or available but hspa+ is. I think the modem responsible for switching between lte and hspa+ causes calls to drop. I took note of it a couple hours ago when i attempted to make a few phone calls resulting in instant call drops. Seems to do it while switching from lte to hspa+ network. I just wish Google would stop burying their heads from the outside world like an ostrich, and get in top of this. I mean this is their flagship device until N6 goes on sale. They should seriously fix this issue or at least stop denying that they've never heard of any complaints with their N4 and N5 customers. I love this device, but a simple fix like this not being addressed by Google is not very professional, especially because it's primary function is to call people. I'm really tempted to flash those radios, but really want to see if Google addresses this issue with an official ota lollipop update.

Factor resetting it won't help, I've tried it already.

part of the price? no. you dont see any phone more expensive because it can handle lte. your issue is with your network, and its signals around you. as we all know that the lte available can not handle voice calls. your isdue involvez lte handing off to H or 3G. thats where your network comes in.

Then why does my moto g work fine in the same locations? And LTE isn't more expensive on a phone? Please explain then how a LTE phone is more expensive then the 3g variant. Go compare the moto g to moto g LTE. Defeats your argument.

lol, ok. the moto g variants are an exception to the majority. their already cheap price point being the reason.
those are two different devices, with differing hardware. its possible that moto can catch the signal from a little further away than the n5 can. the n5 was made less expensive because they used less expensive hardware in places. a shorter antenna being one of those places.

anyways, if you bought it from google, you can request an exchange.
I wouldn't try any hardware mod, etc as the issue is with the software. This kind of thing happens to me also, regardless of where I am or what network I'm on (tested this with a friends AT&T sim also). In the settings menu my signal strength just says "0" (kid you not ZERO) and sticks there until I manually set the phone to 3g when I go to a place with weak LTE (like a basement).
DISCLAIMER: I am only assuming this as I don't know that much about this topic, but I think stock 4.4.4 doesn't understand that LTE can still be received at worse than -115dbm and causes this fault. It doesn't matter which radio you flash (using the newest dev preview radio on 4.4.4 still has this issue, but on 5.0 it works flawlessly), what network you are on, where you are with strong LTE coverage... If you go to the wrong LTE dead spot you have this issue. It's as if the radio is saying "I'm still good on LTE" and the phone says "-115dbm isn't good we need to switch" and the radio says "I'm still connected to LTE though" and the conflict causes the signal to go to 0. I don't think it's got anything to do with the handoff from LTE to 3G either (but it might, as I said I'm no expert). -115dbm seems to be the doom number for me on LTE with 4.4.4.
Try flashing the new dev preview if you want LTE. No network = 0 bug. Hell I can even get LTE in my basement (at worse than -115dbm, of course). I had to flash back to 4.4.4 though, too many games/apps not updated yet.
Long story short, this is fixed in Lollipop. Less than two weeks...

if it worked until august, then it supports my point of probably being an issue with your network, and not the phone itself.

But then why does my moto g work? Why is the issue also all the way from Philadelphia to new jersey to new York. That supports software if you ask me. Also it working it lollipop supports software. Also if it was network I think we would hear more about this issue from other phones as well
