Poor signal - Verizon LG G3

Do you guys have poor data coverage with your LG G3s? I don't know what it is with these new phones, my Thunderbolt used to have LTE almost everywhere I went, and when I lost it, 3G picked up instantly so I almost never lost mobile data. The phone I just switched from, a Samsung Note 3, and now the LG G3 seem to have terrible data. It barely picks up any LTE signal, and constantly drops to 3G and then loses data all together, then when I lose data, I need to turn off mobile data and turn it back on again. Is this a bug with lollipop? I am currently running Jasmine 8.0 on my G3 and was completely stock on the Note 3 no root nothing running Lollipop 5.0.

Same here. Better LTE with old HTC X8.

[Q] Constant Switching Between 4G LTE and 3G

Hi all,
This question might have been posted already seeing as this phone is about a year old already. I'm running the STOCK ICS ROM OTA 4.0.4 unrooted. I've noticed that after the update my phone keeps switching from 4G to 3G and back but the problem is so bad that I lose every bar of signal (i.e. empty bars and of course no data) for at least a minute when the phone switches. I've already gone through the process of getting a replacement phone and I will need another because the receiver (speaker inside when I make a phone call, not sure what its really called) sounds awfully tinny and when the hang up tone plays the speaker sounds like its about to blow out. I lowered the in call volume to half, but it still doesn't work and my phone sounds tinny when ever someone talks during a phone call. I never had that problem with my old RAZR. As for the data issue, I am aware that I live in an old building because at the most I get between 3-4 bars of 4G LTE but sometimes as low as 2 bars. However, outside on the street I get full bars of 4G LTE and it still switches back to 3G on it's own. I have tried Motorola's restore connectivity app on the play store but that didn't work and I don't have anything like smart actions or LTE on/off app running on my phone.
Is anybody else having these issues? At first I thought Verizon sucks in my house but it doesn't I still get crystal clear sound on calls and text messages are promptly sent and received. I also, of course, live in a 4G LTE area with good solid coverage. As a control I have an iPad 4G LTE with Verizon on a separate account and it consistently stays connected to LTE. It never drops below 2 bars and the LTE of course maintains its fast speed. On the other hand, the RAZR, will switch between both technologies at least 5 times a day if not more. I know that they both have different radio technologies but they should at least be similar in some respect. I have also seen an iPhone 5 at the Verizon Corportate kiosk at my local mall. It's obvious there are repeaters but they are not for 4G because none of the phones are on 4G, they are on 3G. The iPhone 5, however, had one bar of LTE and it loaded up a web page just fine and I never saw it drop back down to 3G. I'm trying to see if there is a solution. Have any of the Jellybean ROMs addressed this issue?

AT&T users running ARHD or TrickDroid: Any signal issues?

Apparently some people are having signal issues (i.e., dropping between HSPA and LTE where other AT&T phones are rock solid LTE) with the Developer Edition. HTC has said the Developer Edition may have signal issues since it is not "optimized" for AT&T. A few people have commented that ROMs based on the international HTC One may also have signal issues while running on the AT&T HTC One.
So for those of you running international roms such as Android Revolution or TrickDroid -- are you having any signal issues? Is signal strength as good as it was on stock AT&T ROM? Any trouble holding on to an LTE signal?
Thanks.

I wouldn't say that it's much an issue, but that the international roms show Att true signal strength. For example I have one bar of LTE in my house and my wife's iPhone 5 range from 2 or 3. My LTE speeds are almost double hers. The bars being shown whether on stock Att or international doesn't mean much. A good way to check signal strength would be to compare your db's.

No issues here. DBM signal, speeds all awesome on the International Roms. AT&T likes to make you believe that your signal is better than it really is.
Signal bars are a lie.
I have -95db signal and decent LTE speed

Thanks to all for the feedback.
Just a note though, that some aren't complaining about the bars, but about actually dropping LTE connections where other AT&T phones do not.

Yeah, that happens with me in my house sometime (if in my pocket etc) . Somewhere in one of these threads someone mentions how the international will drop connection at about -115db or something and Att drops around -125db. So that could be the reason.

I flashed my One to the Maximus 7 Rom and have noticed lower bars than usual. I live near a cell phone tower and all phones that I have had as well as others on ATT always have full bars while I can't seem to get more than 2-3. Today my phone started switching between H and LTE and acting weird while driving and it has never done that before. I'm on the latest 1.29 radio firmware and it hasn't helped...not sure how to fix it and for those saying this is just the true reading of signal, I doubt I would be getting such low signals when Im literally about 3 blocks away from a cell tower.

I did notice this too. I definitely have lower bars and lower speed as well....I have trickdroid 5.1 installed. I tried the ATT version before getting the dev version and I did not have this issue.
TrickDroid and ARHD both show true signal bars, but they will also switch to 3g from LTE sooner than the stock ATT load. they seem to switch at aound -120db where ATT will hold out until -130db. if you select att from the ARHD load, it hold on till about -125, still not the same but it works.
Like another person said, the stock ATT ROMs show a non real signal strength, where the Int'l ROMs do. It's all about your actual data speeds and the dB signal. I'm running ARHD 7.0 and have zero reception trouble. LTE speeds are fine.
Just replace /system/framework/ext.jar from an AT&T ROM and you'll get the "fake" AT&T signal icons...
Yup

My Co-worker cant keep the LTE signal for longer than 10 minutes.... and the phone gets hot as heck...is yours hot?
HTC One AT&T Variant TrickDroid 5.2.1 ROM with AT&T tweaks.
RSRP(dBm): -105 to -110 avg. RSRQ(dB): -10 to -12 avg.
No LTE troubles but I did notice during the ROM install before I picked AT&T as carrier it flaked out a few times saying something else besides LTE and H and kept going back and forth.
TrickDroid rom with AOSP icons are showing 1 to 2 bars. - At the bottom!! Whereas my stock rom was showing like 3-4 bars all of the time at the house.
SpeedTest with both roms at my house (not on wifi) = 15M down. 10-20 AVG. regardless of ROM.

Verizon lg g3 on T-Mobile will ROM help

I just recently got Verizon lg g3 and I am tryint to get LTE, but nothing has worked changed APN and network settings. Only getting edge speeds.
I am Wondering if there is a custom ROM that I can add to the Verizon lg g3 in order to get T-Mobile LTE coverage.

Make sure you have the LTE apns for T-Mobile. If that doesn't work. Maybe you live in an area where the T-Mobile bands supported by the Verizon G3 doesn't exist
I get LTE in the RDU area of NC, or H, but down east along the coast I pretty much only get EDGE. Same thing though on my One Plus One, So it's just T-Mobile.

I don't know if it has anything to do with cloadyfa's 4.4.2 international Rom, but I had multiple problems with running my phone on ATT (no mms while connected to Wi-Fi, constant data/connection loss resulting in missed/late texts and missed calls as well.) Anyway, long story short, I never got lte anywhere in my small town even tho my other 2 phones got lte just fine. After flashing his ROM, I never have data, mms or call problems. It honestly feels like this phone was made for ATT now. Data connected as soon as the phone booted too. No need for manual apn input!

Awful reception everywhere?

Hello everyone,
First post on XDA woo!
Anyway. I've been with android for since the Galaxy Nexus and continued using the nexus line up until the Nexus 5. Recently I got bored of stock android so I wanted to try out the LG G3. I'm currently on T-Mobile and was able to get a Verizon LG G3 basically for free. Popped my SIM card in, set up a T-Mobile APN. It worked fine. However. I have NO signal almost anywhere I am at all times (school, home, when I'm out and about). Could this be because of my APN? Is it a faulty phone? Because I'm using t-mobile on a Verizon phone?
Thanks in advance guys!
(Ironically enough, I have decent signal in the screenshot. Haha, I promise it's a miracle)

Welcome to the XDA forums!
Actually your screenshot is showing only one bar of signal
What do you have the "Network Mode" set to? (Under the "System Select" settings.)
The 3 options are Global, LTE/CDMA, and LTE/GSM/UMTS.
For T-Mobile you probably need the LTE/GSM/UMTS mode.
Here is a thread where someone else set up their VS985 on T-Mo's network.
http://forum.xda-developers.com/verizon-lg-g3/general/factory-unlocked-lte-t-mobile-t2828543
Thanks for the warm welcome!
I checked my mobile settings and it was set to 'Global'. However when I tried switching it to either of the other two,options I get this error message (shown in the picture below).
I read the thread you posted. Unfortunately I couldn't find anything to help my specific case. I did find out that this phone reads a Band 4 LTE from T-Mobile. I went online and it seems that my area doesn't get Band 4 coverage for LTE. However even on my Nexus 5 I never got LTE because I think my data plan only,covered up to HSPA. Could this be a problem?
Thanks for the help.

Whoops. Forgot the screenshot. I don't know why but it's not letting me upload it.... Hmm. I'll just quote what it says.
"The network is not available. You can try global mode to see if alternate networks are available. Do you want to set network to global mode?"

I use a VS985 on T-mobile, so I would offer my 2 cents. The only LTE band it supports for T-mobile is band 4, so if it is not offered in your area, you won't get LTE, but you can still get H, which is still quite fast. Your APN setting is correct. The signal bar for T-mobile is always low, usually 1-2 bars, but the LTE does not seem to be affected by it. I am in the Bay Area, and I typically get around 25Mbps and can get up to 57Mbps when at late night. I think it has to do with T-mobile network than the phone. In fact, I get slightly better signal on G3 than my Nexus 5.
Hmm. I am out of ideas. I mean, my Nexus 5 got great signal throughout my daily routine. Now the LG G3, with the same SIM card and data plan, gets NO signal. Not just BAD signal. I mean NONE. I'm starting to think it may be a faulty hardware problem? I might try and return it and try my luck with another phone. What do you guys think?

I noticed a drop in signal strength when I flashed to Lollipop... Long story short I hated Lollipop and with the radio not as good just Flash back to 10B and setting it up now and will leave it there. I never had any issues with 10B
Someone here on XDA mentioned that the Nexus5 supports band 2 LTE, which T-Mobile uses increasingly as it "'re-farms" it's old gprs towers. I know the G3 doesn't, and I am pretty sure the Nexus5 doesn't either, but if the other poster was correct that could explain your observations.

I have Nexus 5 too, and that phone supports every band in the US including LTE band 2. T-mobile main LTE band is 4 but in some areas they use band 2, which is not support by G3. If you still have your Nexus 5, install LTE Discovery from Play store and you can check which LTE band you are on. If band 2, then you will need to sell your G3. Or I can sell my Nexus 5 to you, haha.
One more thing, I was playing around the Network mode on my G3, while it makes no difference in LTE reception, "LTE/GSM/UMTS" gives better 3G reception, so that is the mode you want your G3 to stay at.
Alright. So I tried the 'LTE Discovery' app. Unfortunately I couldn't learn anything as I don't actually recall ever getting LTE in my area (except at my fathers workplace a good ways a way. Probably since there is a cell tower right next door. Haha) Anyway. I'm thinking that the band receptors are my problem. I'm considering maybe returning this Verizon G3 and buying the T-Mobile G3 variant instead. Do you guys think I'll see any improvement?

Not if you are in a T-Mobile band2 LTE area. Even the T-Mobile G3 does not support band2 LTE. No LG G3 does.
It does support the high band, band21 I think, which is still more common for T-Mobile than band2. The vs985 doesn't support T-Mobile high band LTE. So, getting the T-Mobile G3 might help. Just remember that higher frequency bands tend to not penetrate buildings as well as lower frequency bands.
I looked at that LTE Discovery App... I would not leave that on your phone. It's a data miner.
Needs access to...
Device and App history
Location
Phone
Photos / media / files
Device ID and call info
Really all that. I don't think so. I would not install it at all. Just saying.
Some if these apps are crazy for what they want access to. I stay away from them.

[Q] Why is my 4G LTE speed slowing down?

I just got a used LG G3 on Ebay the other day. So far it's been great (big improvement over my Galaxy S4, IMO). But I've noticed something strange. When I reboot or toggle mobile data, for the first few minutes, my 4G LTE speed is great. Then, after five minutes or so, it slows waaay down.
I installed the Ookla Speed Test app and am seeing it go from ~8-10Mbps initially down to anywhere from 0.2-0.8Mpbs after a few minutes. I've also noticed when it happens, at first I'll have 4-5 bars of LTE, but then it drops to 3 bars and the slowdown starts.
I thought it might be the ROM, but so far I've had stock 12B, stock 10B, rooted 10B and rooted 23C. All of them are having the same issue. I'm currently rooted and running the Eclipse ROM.
I haven't seen any other posts about this, but I did see a few about wifi switching, so I wonder if that may be playing a part.
Any help would be appreciated. Thanks!

I am on 10b rooted, and I don't have the LTE slowing down issue. Could that be your Cellular signal not stable in your area? If signal is OK, then it is probably a defect in hardware. Flash back to stock 12B and send it to LG for repair.
