LTE after making a call. - Verizon LG G3

Hey everyone. I just picked up a Verizon LG G3 over the weekend and I am using it on Cricket Wireless (ATT). And everything works great, I have the APNs set up correctly. The only issue I seem to have is that I will be connected to LTE on ATTs network, and when I either receive or make a call it will disconnect from LTE and will connect to global (my guess since it will show a G where it would normally show "4G LTE" or "H". And once I disconnect from the call it connects to the internet again but only to HSPA+ and not back to LTE even though I know for a fact I am still in a LTE supported area. In know this because the only way I seem to be able to connect to LTE is to turn off mobile data and turn it back on. My question is, does anyone have this problem on the Verizon LG G3 while using it on Verizon's network or with ATT/T-mobile?
From what I know the phone should automatically connect to LTE again after the call, not HSPA. Thanks.

Not sure if this is what you want, but perhaps try System Settings, and under Wireless Networks select More, then Mobile Networks.
In Mobile Networks, try System Select. Press "Network Mode" and try adjusting to one of the other options. I'm strictly Verizon, so I changed mine from Global to LTE/CDMA.
Worst case, you don't get connectivity, you can go back and change it again.
HTH!

issues reconnecting to mobilicity network -canada, please help!

Hello there I currently have an unlocked vibrant currently on the mobilicity network in Toronto, Canada.
The phone works well, no issues except for establishing and securing a connection with the network provider. Every time I go to an area where it loses service, like parking garages or subways it loses the connection- obviously- but when you get back to an area where there should be service I only connect to the roaming service. This is leading to extra costs since my plan has charges for that.
What I do now is when i go somewhere with no service i switch to flight mode. When i get back where there is service i have to usually turn the phone off and restart it and search for a network manually.
Are there any apps, hacks, or fixes that can stop me from seeing or detecting roaming services, and force the phone to lock on to my network provider's service?
I want to use it only in the current home zones, and if out of one, i accept the fact that the phone does not work at all. I am always in the coverage zone and never want to use it while roaming.
can anyone help?
At the setting, there is an option there Data Roaming, you need to check or uncheck it. Select the option that will prevent you from doing data roaming and that should fix your problem.
On the otherhand, I have a question for you. I have the same phone and same provider, mobilicity. Our problem is the 3g connection. It is spotty sometimes the 3g icon appears and then disappears. Does this happen to you? I noticed the problem occurs when I go under like basement when there is no signal. After resurfacing, I gell signal reception sometimes full but the 3g or data connection won't work. To solve this, we would usually shut down the phone and restart it. Do you experience the same problem? If yes, what was your fix. Thanks.
David
Same problem here. Any guidance will be appreciated.
I've done the suggestions for Wind but to no avail.
same mobile , same provider , same issue
hai guys i have the same issue , but my thing is more worser than you.....when ever i go to an underground parking my 3g gets turned off and wen i come out from that place i cant able to make or receive any calls .....i need to restart the phone to turn on the signal again...its really weird any one have the solution ?????
Hey all, I have a Vibrant on Wind, this is what I do.
Go to settings.
Wireless and Network -> Mobile Network -> Network Mode ->WCDMA only
This enables that you stick to Mobilicity's 3G network and not roam on the Rogers 2G network.
If you lose signal, you will not roam, but simply not be connected until you move out and pick up Mobilicity's signal again.
Hope that helps.

I found this on Howard forumns:.... I know this post is old but the solution could help someone who recently bought a old for to get used to customization /flashing.>>> Hope its useful
From Post:

It works!!! It totally works!!!! I love it! Thank you so much guys!!!! Now I don't have to restart my phone EVERY morning as soon as I pull out of the underground garage in my car!!!
Thank you, Thank you, THANK YOU!!!!!!
Dial: *#*#197328640#*#*
Click [1] debug screen
Click [8] phone control
Click [7] network control
Click [2] band selection
This is where you make a change, default setting is [1] automatic, which means it chooses automatically between gsm/cdma (Edge vs 3g). So we are going to change this and set it to wcdma band which is 3g.
Click [2] wcdma band
Click [1] wcdma all []
Now it should display “select wcdma all bands[*]"
Now on the bottom of your phone, click the menu key, it’s the one next to the home key, now click back, menu again one more time, back one more time, this is just to confirm it set to number 2 wcdma band.
Now click menu key one last time, click end.. and you are done. Now to double verify that the phone is locked into 3g, dial in: *#*#4636#*#*
Then click phone information Then scroll down to “set preferred network type” It should now have listed “wcdma only.” PS, if you tried to do a shortcut, and just set wcdma this way first without doing the lock above, it would just go back to gsm/cdma auto once you exit the screen.
Your phone should now be locked into 3g.

Again found on Howard forumns and copied and pasted to word doc. to keep for my mum as she gets the phone.... I got her the the 27.50 holiday plan so she can call anywhere to anyone in North america with unlimited data....coverage is good so far...
P.S. i dont allow roaming as to not incure more charges.
I know this is an oldish thread but.
Trying to fix connection issues and the Dial code does not work for me. It just does nothing when I enter that. The only code that works is *#*#4636#*#* and that does not help me.
Anyone else having this issue and know why it's not working. I have an Amaze 4G. Only posting here about this phone because this is the only thread I could find related to my issue.
Searched all over now. Those codes are to be the only solution and they don't do anything on my phone.
Anyone have answers?
I have a mytouch 4g (it's actually the htc panache) that just suddenly wouldn't connect to the network after I restarted it. When I try to add a network manually, the only option I have is to connect to Canadian roaming...

[Sprint-Q]Regarding Mobile Network setting and LTE.

So there is a setting burried down in Settings, More settings...Mobile Network. There are two options. CDMA and CDMA/LTE/EVDO. The CDMA option was selected stock. I have changed to the CDMA/LTE/EVDO option. Does this mean I will see/connect to LTE towers as they start lighting up in Atlanta-metro next week?
Or will I have to wait for some push update from Spring/Samsung that adds another connection type (e.g. Wifi, Bluetooth, etc...) to the mix?
The reason I care is that I don't want to root my phone until after I know it will work with LTE so I can ignore the sprint updates after that.
Help?

International Roaming

Anyone have issues roaming? I'm in Paris and can't connect to a local network at all. Won't even register. WiFi calling seems to work, but I can't get even an emergency call to connect unless on wifi

Did you add Roaming to your account before leaving to France? I would also make sure that:
1. Network mode is GSM/WCDMA/LTE Auto
2. If you search for Network Operators from your phone, does it find anything?
3. Ensure that Data Roaming is selected
Also, power off your device completely and wait for 5 min before switching on (NOT AIRPLANE MODE). These tips have worked for me in the past, not with this phone but with other GSM phones. Please let me know any resolution, I will be going to the EU very soon and I'm hoping to know the experience from another TMo user.
Hope it helps!

How to get T-Mobile LTE working (And Stable) On Sense 6 Roms with a Verizon One Max

Hey guys, I have a few questions that I need to get resolved which MAY help in getting LTE Working solid on Verizon One maxes for those who Have T-Mobile, but I would like to confirm that T-Mobile LTE does work on the Verizon one Max. You don't need to flash ANY special Radios. You can even use Verizon's Latest Radios and it works. All that needs to be done is use *#*#4636*#*# to change the preferred network type to GSM/WCMDA/LTE and boom, it works. The Problem I am having is that you have to switch to GSM Only first, just to get it to Work on T-Mobile before you switch to GSM/WCDMA/LTE. Another problem is that when you reboot once or Twice, my radio keeps on going crazy Rapidly switching from No Service to T-Mobile and Back. I go back into *#*#4636*#*# and I see that it changed to EvDO+CMDA/LTE Mode. I would have to go back and switch to GSM only to fix the problem then back to GSM/WCDMA/LTE Mode to connect to the network again. And yes I have the fast.T-Mobile.com APN Already inputted. This is with both Verizon and Sprint Sense 5 or 6 Roms. So we know LTE works on T-Mobile with the Verizon HTC One Max, But it won't stick. However, I decided to Flash a Cyanongen 11 Rom to the One Max, I am able to go System > Mobile Networks > Preferred Network Type and switch it to GSM/WCDMA/LTE, Reboot, then go into dialer and enter *#*#4636#*#* and Switch to LTE/GSM auto (PRL) and it works flawlessly. No matter how many times I restart, I still instantly connect to T-Mobile's LTE Network. Texting and MMS works with no issue. So what I think the issue is that On Sense roms there is only 6 Different Preffered Network types to choose from but on the Cyanongen 11 Rom, there are over 15. Also, On Sense ROMS there is only a GSM/WCDMA/LTE type with no Auto and I think that's the issue. There is no LTE/GSM auto (PRL) Selection in Sense roms. Because when I choose GSM (auto) on Sense, I can connect to HSPA, 3G, and EDGE with no issues. So I am asking for some help in How can we get more Preferred network type selections under *#*#4636*#*#. Or is there some scripts we can change with the current ones that resemble a LTE/GSM auto (PRL) Selection. But I think that is the culprit in Getting LTE fully working.
And just to Confirm that LTE is working on HTC One Max Verizon Version.
Even when I put my phone in wcdma/gsm/lte my service stays outputting no signal. Even when I reboot it stays like that until I change the network mode.
I wish t mobile released a one max so we could get WiFi calling

I have come to use xposed module Intelli3G to auto select the network. It has to be set to you liking of network chose.
I'm trying to do this too. But the roms I have tried so far won't let me get into *#*#4636#*#*. What Rom did you use to get into it?

This does seem to fix one of the Issues, but I am getting Signal Dropouts on LTE when going from Tower to Tower and have to turn on and off Airplane Mode to get it working agian. Do you ever experience this issue?
I don't have to use airplane mode to regain a signal. In my area T-Mobile has spotty signal strength. That is one reason I use LTE but only when signal is fair to good and for long video streaming. Hspa+ for me is better on battery and suffice for Tapatalk, email, mms, market downloads, apk even short videos, etc. I stream more on the weekend because it football season.

I use to Have a Sprint One Max with it Unlocked as well and I only got HSPA+ Speeds with it. I never Went about getting LTE to work because I though it didn't have the Compatible Radio inside of it. I am hearing that the Sprint Version has the Same LTE bands as the Verizon Network Uses. But I would try to go into you *#*#4636#*#* (or Download Network from the Play Store) And try switching your preferred network to GSM/WCDMA/LTE and see if it works. Make sure, that your APN Is set to the Fast.t-mobile.com One also. That is all I did to get it to work on the Verizon Version.

Same here. Also, I tried switching bands and it did seem to fix the Problem, However it prevents me to Call out or Receive Calls because usually when making or Receiving a Call, the LTE Band goes back to 3G/H/H+ because T-Mobile hasn't Activated VoLTE yet. But it is good to know that LTE does work but it's not really Stable and Global Phone Friendly. The Problems really happen when Driving around or Going from Tower to Tower. Signal goes from perfect to NULL and just stays at 1 or 0 Bars no matter where you go. And you either have to Restart the Phone, Turn the Radio off then on, or Just simply Turn on and Off Airplane Mode to fix it. So I am just using WCMDA or GSM Only for the time being and I don't really want to go to a AOKP CM11 Rom because most of the Features I use aren't there. And just to Clarify, Switching/Flashing Radios and basebands does NOT Fix the problem. I have tried All sorts of Radios, even from T-Mobile HTC One Phones and just doesn't work.
I had used the steps in the link pasted under this to get my LTE working perfectly on the stock Verizon ROM with Sense 5.5 but after upgrading to Sense 6 these changes have caused some issues. The changes worked fine for a day but then the second day mobile data stopped and nothing I did could bring it back. I ended up having to flash a stock rom RUU to get mobile data to come back. I'm not sure why the data stopped on the second day, I may have been from other changes I made to dpi or adding on screen buttons or re-locking the bootloader to use the fingerprint scanner. For now I'm just using gloabal mode which gets me good 3G till I re-gain my courage to try modifying the settings to get the LTE again.

Anyone using this phone with AT&T in the US?

I love this phone....there, I said it. But it's driving me crazy.
I bought it from a Chinese retailer, who shipped it with X821 firmware, but the box states that it's an X820. I doubt there is any difference in the hardware.
I would have left everything as it was, but I can't seem to make phone calls (don't have a data plan yet...yeah, I know....) with anything other than 2G, and that is about to go extinct. When I set it to WCDMA, it shows a UMTS connection, with no carrier designation, but the tower is the same one I connect to with 2G. The phone does sometimes show an AT&T 3G connection in the status bar, but I can't make calls, even though I have full signal. When I place the same SIM in my old HTC Inspire, the same monitoring app shows "UMTS - AT&T HSDPA+" and works just fine.
I'm at my wits end. I have rooted, installed TeamSpain recovery, replaced the firmware with the X829 and even tinkered with the frequency configurations through DFS Studio (which did a lot of complaining, and I'm still not sure if the changes stuck 100%). I also played with APN settings and tried the SIM in different slots, both alone, and with another SIM. And after all of that, still no progress in getting this phone to use a 3G or 4G connection to make calls. If I don't set it to "GSM only", no phone calls in or out. I'm essentially right under a tower, so signal shouldn't be an issue.
If anyone is using the same provider in the US, and is not having these kinds of issues, I'd really appreciate hearing what firmware you are using, and/or what you did to get things working.
I am using it on x820 with official stock 0.17s firmware, and did a dirty flash to cuoco92's 17s firmware. Everything works including HD voice calls, and full LTE.

I tried this, as well as the Remix ROM. In fact, I think I've tried just about everything, without success. At one point, I had one of the apps indicating a 4G connection, but the phone diagnostics showed GSM (2G). Even the apps aren't all sure what to make of what's going on with the connections reported by this phone.
Currently on the cuoco92 v35 ROM. When WCDMA is enabled, I see simply a good UMTS connection , sans carrier name, in the "Network Cell Info Lite" app, and no ability to make calls. I also often (but not always) see the "AT&T 3G" sign. 4G or LTE never shows at all, even though the diagnostics show that the phone is communicating with an LTE transmitter, when preferred network is set to "unknown". It won't even let me set things like "LTE only".
Any chance you could set your phone to WCDMA and see what the "Network Cell Info Lite" app shows you? Anyone else with this phone on AT&T?
BTW, I am now using a data plan, which I thought might make a difference. It doesn't. EDGE data only for me . New SIM card is on the way, but my hopes aren't high.
Is it possible for a Chinese seller to have borked the phone so thoroughly with their x821 ROM (it's an x820 marked phone), that it keeps any subsequent radios from flashing properly? I don't know how/why it would work for some and not others.
Starting to really dislike this "phone"......it's more of tablet at this point.
Thanks.
I think APN is not set for AT&T
try this:
"Main steps
To use data services on our network with a non-AT&T device, you may need to program the data settings. The sections below provide the correct settings and steps for programming based on your device type and operating system.
.
Access the Settings menu.
Locate and select Wireless & Networks or More Networks.
Select Mobile Networks.
Select Access Point Names.
Locate and select the option to add a new APN. This is usually accessed by a + symbol on the screen or by tapping the menu button.
Program each field using the settings below.
Save the changes to return to the APNs menu and select the new APN.

Thanks, but I wish it were so simple. I have tried this, and other APN settings. None work to get this phone to be usable on anything other than 2G.
I just received and activated the replacement SIM. Still no improvement. While typing this, I have Network Cell Info Lite app running, and with the Set Preferred Network Type showing "Unknown" in the phone's diagnostic screen, It will switch randomly between "EDGE AT&T" (which works fine) and "UMTS -" (which is useless). Both have strong signals. For a split second before it switched to "UMTS-", the app showed "GPRS AT&T", but only for a split second before it kicks over to "UMTS-".
I wish someone using this "phone" on AT&T in the US, would run this app to compare notes. It may be that that the phone works fine on a full implementation of LTE (i.e. in locations where AT&T have already deprecated 2G) but not in other areas. Still, that doesn't seem to explain why this phone seems unable to register on the same 3G network, used easily by my other phone, with the very same APN settings and SIM.
You would have to call att and check if they turned our phone on to use lte. If your phone is not "registered" as an LTE capable phone it wouldn't be able to pick it up. This phone has all the bands needed for AT&T because I am using it now. All LTE work straight out the box, and i'm on the latest 19s cn rom

I'm a bit confused. Is this what you did to achieve proper function of this device? I.e. calling AT&T and getting them to do this for you? My conversation with their tech person didn't seem to bear fruit in this regard.
Also, which slot do you have the SIM card in? I've used the stock 17s and now on cuoco92 v35 ROM. There definitely seems to be a difference in how the network settings behave, based on the location of the SIM. At one point, after selecting BAND 6 (when it would let me), the phone showed a constant "AT&T 3G" connection, but it was useless. No calls and no data.
