Hello
The problem i have is for the Dual SIM version (HongKong).
Every tyme the phone is restarted the Prefered network mode is reset back to default mode : GSM/WCDMA auto
The options I have are:
GSM/WCDMA/LTE auto
GSM/WCDMA auto
WCDMA only
GSM only
Has anyone else experienced this and would you know where is the best place to report this to LG?
thank you!
I'm experiencing the same issue when using on T-Mobile. I've even modified my APN settings to match TMO GS8, small change in APN type.
I submitted feedback to LG HK, https://www.lg.com/hk_en/support/contact/chat-email/email
I can confirm this behavior is the same on my H990DS that I'm running on the telus network in Canada. Every time the phone is restarted it always defaults back to "GSM/WCDMA auto" instead of "GSM/WCDMA/LTE auto"
I wrote LG support in canada and they told me they couldn't help me because it's an international phone. And that it was probably a problem with my APN settings (what a pathetic cop out canned response). There is obviously nothing wrong with the APN settings, as it has no problem grabbing an LTE signal when I set the preferred network mode to "GSM/WCDMA/LTE auto"
The issue, is that the phone resets it's preferred network mode to "GSM/WCDMA auto" every restart. As seeing that other people are experiencing this same issue in completely different carriers pretty much says that this is problem with the phone .
Has anyone found a solution?
I have the very same issue, i the past I have used an app that I could force a 1x rtt connection on a cdma phone, the app itself used the advanced phone menu to do this, but a lot of these app don't work anymore and haven't since kitkat, but I don't suppose it'll hurt to try, the one I used for my cdma phone was for the HTC thunderbolt, had a gray or black round icon with a little red lighting bolt.

Hey all yes I am a newbie, but I have been using roms for a quite a while I love the customization of the HD2, we are switching services in a couple weeks to either Verizon or US Cellular but this issue is bugging me like crazy, I used to be able to use my phone in the parking lot at my job, we arent allowed to leave on break, used to get 2-3 bars and an Edge signal, in a place Tmobile says I should have great coverage over the last couple days I have gotten no signal what so ever in the same place I used to use my phone every single day for about a year. I sit there for my whole break trying to talk to my wife while refreshing networks, auto selecting it or manually gives me 4 full bars and an edge signal then it all goes away. I guess why I am posting it to see if anyone has suggestions to what I can do to fix it. The phone works fine at home and on the road just not near work anymore. I have always used different roms, and never had the issue at all, always full task 29 wipes, my current build is
CyanogenMod Version PARANOIDDROID
Kernel 2.6.32-ics_tytung_HWA_r2.4_uniMAC [email protected] #272
Baseband 15.42.50.11U_2.15.50.14
Any suggestions are appreciated! Thank you again! Jake
I well ask a obvious question, have you checked your APN's. I knowyou are getting a data signal but maybe one of the APNsettings need to be changed.
Also do you have you checked in Settings/Mobile network/Network mode. See if you have WCDMA only, GSM only, or WCDMA/GSM auto.

Thanks for the response, my only APN is epc.tmobile.com and I cannot locate the network mode... No network mode setting that I can find.
Edit:: Found it its set to WCDMA Preferred is that what it should be?

Try WCDMA/GSM auto that way your device can switch back and forth as needed between WCDMA or GSM as it needs to.
Hi all, got a really weird problem with Koodo.
I got a new Micro SIM for it today, and it didn't pick up the network so I asked the people at Koodo kiosk to test it and it worked fine on another phone so SIM, or network shouldn't be a problem.
After some fiddling around, I changed the network type in the Testing menu(by dialing #*#*4636*#*#) to WCDMA Preferred (later found that CDMA/GSM Auto (PRL) and WCDMA Only and Unknown) gives me signal and I can make calls, but the default CDMA Auto (PRL) doesn't work.
However, whenever I make a call, there's a little text popup at the bottom that says "Sending", and after call completes, the Phone app crashes and it seems to go back to the normal settings (CDMA Auto)...
So it's a really weird problem... anyone have any insights to solve this?
To add: I did try Rogers SIM in it before, and made some changes to APN and changed the network to LTE/GSM Auto for testing, not sure if that could be interfering with it now because it's using the default APNs.
Another edit: I think reason Phone app crashes is because it's the Testing app where you select network type that crashes. If I exit out of that before making the call it doens't crash.
Are you by any chance using the lte toggle in aokp? I remember when using that it crashed the phone app, which aokp build are you on?
The phone should default on WCDMA Preferred, and if you have lte use lte/gsm auto.

Yeah I do have the LTE toggle in AOKP, but I think the crashing was due to having the testing app open.
Anyways, it seems to default to WCDMA Preferred now... dunno why it wasn't on that before, because I rebooted many times and it always no signal. It seems to be all good now, no crashing and signal's strong.
If you used the lte toggle in aokp it would defaul to cdma, then after a phone call the phone app would crash, the only way to solve that would be to wipe the phone, been there done that.

Mine is back to defaulting to WCDMA Preferred... Is it because I set it to that manually?

Yes, if you use the lte toggle it'll default to something else since the lte toggle wasn't made for the nexus4.
Glad to see you appear to have made progress here? Apologies if it was AOKP related issue and not straight forward apn as it sounded in kernel thread.
May be with warning others back in ROM thread once resolved and if you're 100% sure toggle was cause?

I tried searching however could not find anything. Perhaps I may be using the wrong wording.
What I am trying to accomplish is to disable the GSM mode. What I find is the phone likes to jump to the GSM network and with that the internet connection just doesn't move at all. If I force the phone to WCDMA mode it work just fine standing in the same spot, so the phone is still picking GSM over WCDMA even when there is a good signal for WCDMA.
Current modes:
LTE/WCDMA/GSM (auto connect)
WCDMA/GSM (auto connect)
WCDMA Only
GMS only
Is it possible to have a LTE/WCDMA option?

I miss this option. The Xperia Z had this mode, I loved it. It was reachable via the common code *#*#4636#*#*. But this code doesn't work on the GT-I9505 with stock Samsung ROMs. But even with custom ROM, and working code. This special mode is missing. There are 2 switches for "LTE only" and "WCDMA only" but not both

App doesn't seem to work, when I hit "Select Radio Band" it comes up with "Set GSM/UMTS Band" and nothing else.

You have to use "prefered network type" as seen here

This should work
Here is my screenshot. It only has "LTE/CDMA", which only allows me to use LTE. There is no "LTE/WCDMA" option.
Perhaps, this might be an idea for rom creators?
also interested in this.
yes, please add this function LTE/WCDMA only into ROM CYANOGENMOD.
because LTE/GSM auto (PRL) connect to 2G/3G/4G, and i'm not interested for 2G.
Did anyone ever find a solution to this?

Solution please ! I have the same problem also
True. I am able to use the following:
LTE/GSM (prl)
WCDMA (prl)
GSM Only (prl)
I am unable to use LTE/WCDMA/GSM
I am using XXUGNG8 modem, and I am unable to use 2G (network won't connect).
3G works in most cases, but it is still dropping. Only technology which works correctly is LTE...stable and fast.
I am unable to switch the network band to any other one. I tried it with service menu tool, but it does not work either (allows me to change to defined items above, and reverts back to LTE/GSM if I'll select anything else).
Is there a way to add support for more network modes? I am confident that my issues are not related to HW, as both bootloader, GSM modem and LTE modem are all of the same version - XXUGNG8, and I do have very good reception for whole band. I am just unable to switch over to 2G, and 3G is still dropping.
I live in Prague, Czech Republic, and I own GT-9505i variant
Any solutions guys?
any solution to this date? im interested in the same thing.
I finally found a solution that works on my Samsung Galaxy S5. Enter code *#2263# into your dialer. An option menu will open with "LTE/WCDMA Mode" only as an option. Works like a charm!
Wrong posted.
Hi,
Sorry to bump this but I have the same issue. I have a Galaxy S4 and it is very weird with its network selection.
The default setting is LTE/GSM auto, which I believe is LTE combined with the GSM Auto mode that everyone knows about - this being, prefer 2G instead of 3G in weak signal areas.
I have the following options:
LTE Only
LTE/GSM Auto
GSM Auto
WCDMA Only
GSM Only
WCDMA Preferred
Plus a load of other stuff about CDMA and EvDo (I'm sure that the GT-I9505 doesn't support CDMA or EvDo?).
The problem I am having is as follows:
Immediately when I got the S4, I realized that it was preferring GSM over WCDMA/HSPA. This was confirmed when compared with a Samsung Galaxy Ace Plus, on the same network, in the same location, and the Ace Plus (S7500) was choosing 3G, whilst the S4 chose 2G. Doing a bit of Googling led me to find the WCDMA setting, and after choosing that, the S4 chose 3G.
So all was good for the last 2 years, using WCDMA Only mode on my S4, as my mobile operator (Virgin Mobile) didn't have 4G access. Losing LTE wasn't a problem.
However, now I have switched to the EE network, I now face a problem. As mentioned above, there is the WCDMA Only mode, and the LTE Only mode - meaning that I am unable to have both 3G (WCDMA) and 4G (LTE) without also having GSM, and there is no way that I want to ever use GSM again, especially since that EDGE/GPRS are barely usable as data connections, GSM has sub-standard voice quality, and the S4 is choosing GSM over WCDMA.
A couple of examples, once on my way home, the S4 dropped from 4G to 2G and completely ignored 3G - despite being right next to a 3G mast operated by EE (albeit on the old Orange code). On WCDMA mode, the phone always connects to the Orange 3G mast. Thankfully, a bit later on, it did pick up 4G again, but if I was streaming Tunein Radio, that would have been a disaster (it would have dropped the stream).
A bit later on, on the same journey, the phone also went to 2G, from 4G - despite being in a reasonable signal area for 3G. Why didn't the phone choose 3G? I'd had enough by then and switched to WCDMA Only mode; result? 28% 3G signal (3 bars)!
It's also happened on my local mast, until a few weeks ago. The S4 was choosing 4G from a more distant mast (strength 50%), instead of 3G from the local mast (strength 60%). When I went downstairs, to the kitchen, the signal strength dropped and the phone went straight to GPRS! GPRS is likely to give about 30kbps max, so I don't know why the phone was doing this - although about 20-30 seconds later, it did then go to the 3G from the local mast.
I can't use LTE Only mode as (a) the 4G rollout isn't complete, and (b) the S4 does not support Voice Over LTE (VOLTE), meaning that in 4G only mode, I have no way of accepting or receiving calls.
I need a 3G/4G mode (LTE/WCDMA) on my S4, that doesn't use 2G at all, because 3G/4G signals are present virtually everywhere on the EE network, and it would stop the S4's crazy behavior.
Any suggestions to remedy this would be appreciated. I am not rooted, though if someone knew how to root the phone for me, it could be a possibility, as it is out of warranty.
On my K3 Note, I can't pick preferred network mode on ANY rom/firmware.
I've tried everything, but it always sets the default preference which is 4G>3G>2G.
What I need though is permanent 2G and I can't set it this way. (4G signal is weak on my operator and then it keeps switching between 4G and 2G over and over)
Is there any way to entirely disable or block 4G on a phone so it will never set that mode again?
Any help would be appreciated!
Any help guys? No one knows what could be the issue?
I tried using the *#*#4636#*#* code and set the "GSM Only" but it still doesn't work.
Is anyone else having the same issue?
Edit:
Also what I've noticed is that while using CyanogenMod (atm), it stays on 2G until I turn the screen off. Then it goes back to 4G.
After turning the screen back on it then goes back to 2G again.
same problem here when dialling number it said invalid MMI code and when switching to 4g the other network appear no signal.. hope someone here have solution. i try several roms but same problem issue.
Well after a lot of fiddling, it seems it works on the stock firmware, but the mobile operator as himself has quite troubling network.
But I think we are slowly coming to a conclusion..
just got the phone yesterday and updated it to the P beta. everything works amazingly well for a beta in my opinion, BUT i cant receive calls. outgoing calls, texts, web and apps are just fine.
spent almost 2 hours at tmobile flipping all the settings around and no luck. any ideas would be appreciated.
Same issue here bro...Incoming don't ring but I get voicemail notifications.... Really annoying, even if it is a DP.
Turns out the beta doesn't play well with the essential LTE. Switch to 3g and calls will come through. Hopefully it doesn't take long to find a work around for it
I believe the people having this issue have volte enabled...try and disable volte (it's broken anyway and more than likely why calls won't ring through) and see if that works
Got same issue... My experience was that I could solve the problem with reboot.
Issue came after playing on settings for mobile network.
Is meaning, when you do this you have to reboot afterwards otherwise you can't receive calls
Try it.

Tried rebooting multiple times while changing settings around. The only way I can get the calls to come through is by going without LTE completely.

Settings/network settings/mobile network/advanced/enhanced LTE?
I had the same issue and to fix mine I just enabled Wifi Calling.
When on wifi I didn't get a call, just missed call notification. After enabling wifi calling, it comes through without issue.
I tested calling off wifi and on wifi and all calls come through good now.
This could be similar, so you guys might want to look at that also.
Good luck!
Heard from a few that this was solved by going into phone app settings -> calls -> calling accounts, then turning on "receive incoming calls". Seems it's disabled to save battery? Can't confirm as I just flashed to try it out and then went back to 8.1 because I like themes too much. Lol.
I'm on Sprint and was never able to make or receive calls regardless of Network settings in the easily accessible options menu.
The following fixed my issue. You can access this menu without downloading an app but I forget how so it's easier to just download the free app https://play.google.com/store/apps/details?id=com.xsquarestudio.forcelte
I had my network mode set to LTE/CDMA when first using this app, and somewhere in the middle I changed it to CDMA but I'm not sure how much that impacted the actual fix.
These were my steps. I'm not responsible for any damage this may cause to your device as I'm not sure if messing with these settings is foolproof or not.
First, opened previously linked app "Force LTE" then under "Set Preferred Network Type" I changed to CDMA only. Enabled/disabled airplane mode. This seemed to do nothing as LTE was still showing in statusbar.
I then chose CDMA auto (PRL), airplane mode on/off, didn't seem to do much either. LTE still showed in statusbar and couldn't make calls. Also "Voice Network Type" showed "Emergency Calls only" inside the app.
I then chose the 3 dot menu and chose "select radio band". I changed that to United States, without resolving problem. Then selected "Cellular 800" and this may have solved the problem, but I continued on and selected PCS, fiddled with some settings in Phones settings menu. Was finally able to receive calls and my signal indicator showed 3G. In app Voice Network Type was listed as 1xRtt. I decided to select radio band once more and chose Class 10.
Calls were still functioning fine. So I went into Main settings menu and changed mobile network from CDMA to LTE/CDMA. LTE kicked in and calls still work!
Again, these settings may only work for Sprint hence the PCS Network option, and I believe Sprint may utilize the 800mhz frequency. The app might show you different options depending on your carrier. I don't know.
Anyway, fully functioning! Woohoo!!

I don't have anything in my settings that says "enhanced LTE" .
Tried using the 4g/LTE and the LTE only options. Neither would let calls through.
I have this problem using the Essential PH-1 with Android 9 Pie in South Korea on the KT network. It should be fully compatible, according to radio specifications, however it only works when I change the following setting:
Settings | Network & Internet | Mobile network | Advanced | Preferred network type | 3G
This is not ideal, since it makes the Internet slow, but at least I can make/receive voice calls. I submitted a support ticket to Essential requesting their official help (I'm well within warranty).
I had the same issue when I use my Att prepaid plan. The problem is caused by wrong network type, you can send text and browse internet, because they use the different channel. My PH-1 wrongly recognized the sim as CDMA/LTE mode, just switch it to 4G/LTE, it will be work. Go to Settings, then search "wi-fi calling", point "advanced" then you can see an opinion "Preferred network type" if you are ATT or T-mobile user, and your preferred network type is "LTE/CDMA“ then your phone cannot make call. Switch it to "4G/LTE", you phone will be work. BTW, Verzion uses CDMA, so if you are Verzion user, CDMA/LTE will work for you phone.
