How to force LTE/GSM/CDMA auto (PRL) or any other Preferred Network Type.

Hello, I have no problem receiving an LTE signal on BCE (Canada) through the Phone Info Menu. I can select any of the preferred network types including LTE, LTE/GSM, CDMA, LTE/GSM/CDMA but it won't stay. Every day I have to go back into the menu and it reverts back to the first selection "WCDMA".
Does anyone know how to force this so it stays on LTE/GSM/CDMA. So it will stay on the LTE-enabled network unless there is a loss of signal and it reverts back to HSPA? It does this automatically when "LTE/GSM/CDMA is selected, but again reverts to CDMA within a day usually.
I did some searches here, but 99% of what comes up is just people asking how to enable LTE or if their network gets it?
Any ideas? Maybe some sort of macro thing.
Regards.

Add this line in build prob
telephony.lteOnGsmDevice=1
Save
Reboot
Now in settings/more/mobile networks u will have an option to choose and it will stick. U have to add the line every time u flash ROMs.
But I keep iron WC DMA/gsm for better battery speed is OK on h+

Thanks for the helpful reply man. I haven't edited a build.prop yet, so Ill have to check it out.

Alright thats all done now, works like a charm. Like that I have the option now either way. I typically stick to WCDMA/GSM when on the road or at work where LTE is spotty, but on days off for around town I would rather just be on LTE as I usually just looking up something quick when Im shopping or something.
Thanks again.

I keep it at LTE, it does have less bars but quality is same for me, speeds are amazing. Also 4G is only data, not voice, so when u have an active call it will change to 3G.(but that's not the phone it's the network)
don't forget to do it again if you flash new ROM, also Tethering WiFi won;t work, there is a fix but it's complected for me, so I just go to W/G if I need to share connection.

So, my Nexus 4 shipped today, and it'll be in my grubby little hands by tomorrow evening. I, unfortunately, can't activate it until March, as I have to wait for my Verizon contract to end, but I keep seeing this LTE stuff, with no real explanation. I do know that the Nexus 4 has an inactive LTE radio in it, but what's the use of activating it, if T-Mobile doesn't have LTE? Is this only for the AT&T users?

There are other threads dealing with who can access LTE in the USA. I am in Canada and on Bell.

I'm in Canada, using Fido. I activate the LTE on my Nexus 4. It works fine, but I'm not able to share internet with wifi hotspot.
I have Android 4.2.1 (latest OTA from Google).
There is a bug with this version or it's only because I activate LTE manually ?

As per the previous comment:

what is the fix to get hotspot internet sharing with the Nexus 4 ? Do i have to had a APn for 3G and swith that it to share my connection ?
I'm with the original firmware. Android 4.2.1

process com.android,phone hase stopped working
i recently got a rom from revolt on my n4 and i switched cdma to lte gsm wcdma auto
i also went into build.prop and wrote down telephony.lteOnGsmDevice=1. i went and to setting, more, mobile networks chose the correct setting. so now i got 4G. great i can make calls. GREAT. but i cannot receive calls...
need help with this. im really choked about this ROM

Even if I select "LTE/CDMA" in the Mobile network settings menu. The settings page keeps displaying "CDMA preferred".
Does this mean it didn't work? In quick settings, I see my mobile data connection as 3G Bell.
LTE only seems to work when using the *#*#4636*#*# trick in the Phone app.

Thanks, but LTE doesn't work in my country, its always stick on lte/gsm/wcdma but it doesnt detect my gsm so i have to manually set it on GSM only but wont stick here every time i restart my phone i have manually set it on GSM only otherwise it wont detect my network
Any advice ?

How can I make "WCDMA Only" the default selection?
Where I Iive there is no LTE and the coverage of the service is quite poor, so the phone keeps jumping between E and 3G/H. I have to manually go into the phone app and select "WCDMA Only" is there a build prop tweak to make the "WCDMA Only" the default option instead of "WCDMA Preferred"?
Thank you.

So is there a way to get the nexus 4 to work on Verizon ??

Aah Crap ! Well thanks man saved me from buying on guess i will have to stick with my rezound for now then

fixed it
For everyone still searching for a solution to this problem, this worked for me. Go to phone information and turn your radio off. Then switch to LTE/GSM/CDMA then power down, DO NOT TURN YOUR RADIO BACK ON. Now remove your Sim card, put it back in, reboot and you should be good to go. DO NOT HGO BACK INTO PHONE INFORMATION OR ELSE IT WILL NOT STAY
If it still isn't connecting try fiddling around with your APN settings.

[Q] Is there any rom that has LTE enabled by default?

Hello!
I'm kind of new on this, I was wondering if there is a estable custom rom that has 4G LTE enabled by default with wifi tethering as well, I am on the T-mobile network in a 4G LTE enabled area and is annoying to do dial everytime I restart or tunr off my my phone to enable the LTE, I am rooted and running .33 radio, THANKS FOR READING.

Look on this thread http://forum.xda-developers.com/showthread.php?t=2209368, that may help you. Not rom related btw, only by the radio. Need root though.

you missunderstood my quetion
I already know that, what I want is a stable rom that has LTE enabled by default instead of dialing every time I restart the phone

If you absolutely must, you can edit the build.prop:
Go to the line with telephony.lteOnCdmaDevice=0 and replace it with:
telephony.lteOnGsmDevice=1
ro.telephony.default_network=9
ro.ril.def.preferred.network=9
You may need to wipe dalvik cache or clear your data. On CM based ROMs this enables the LTE tile in QuickSettings and will save LTE on/off status through reboot. I don't necessarily recommend using LTE personally, however.

GPS doesn't (always) work correctly
Using the .33 or older radios with 4.2.2 can cause continuous autofocus issues (as above poster mentions)
On stock 4.2.2 will cause call audio issues (on T-Mobile, reports say it works fine on other carriers, it also works fine on CM and some other ROMs)
Google Now doesn't work over LTE
Since most carriers don't have VoLTE (Voice over LTE) enabled, when receiving or making a call the phone takes a minimum of 10-20 seconds to switch from LTE to UMTS because a call can't be made while on LTE and calls can just plain fail when LTE doesn't want to be switched off (even with changes, the radio seems to have a lot of trouble switching between LTE and GSM/UMTS/HSPA)
I've made the changes to my build.prop, I just very, very rarely turn LTE on. I get up to 30Mbps on HSPA+, I don't really need LTE, unless I want to brag about getting 50-70Mbps, because it isn't worth dealing with all of the above. LTE is nice if you're in a strong LTE signal area (the radios refuse to switch from LTE to HSPA+ when the signal is exceptionally low unless you switch LTE back off), don't make or receive calls, need a massive amount of bandwidth that's larger than most people get at home in the US, and want to use up your data allotment as quickly as possible.

HOW TO Force 4G only

Hi guys
I've been trying to do this since day 1 with this phone. At work I'm in a spot where I get 2 bars of 4G and it reverts back to 3G . This happens all day . Is there a way to turn on LTE only like you can turn on CMDA only?
thanks :good:

I don't think that's possible, as different areas are bound to have weak, strong or very strong signals.

Upppppppppppppppppppppppppp

IO do the opposite. Turn off lte because sometimes I'm getting weak lte but very strong 3g.

use the Telinfo App from the playstore

Thanks alot :laugh: works fine
Finally

with the recent update on my s4, this is now not compatible to my device... any other alternative app? i used to use this a lot. now i miss my lte connection when im in the office.

Firstly, does your network support VoLTE?
VoLTE is not currently supported by any network in the UK, this means you cannot make or receive calls when on 4G.
What happens is when you make or receive a call, your mobile network forces you down onto 3G or even 2G.
Therefore if you find a way to force your phone onto 4G and your network didn't support VoLTE, you will never be able to make or receive calls.

Did it!!
"Advanced Signal Status" from the GooglePlay worked for me on latest 5.0.1 i9515 phone. It was a long time since i wanted to set it work like i needed.. Now my networks are in wcdma/lte only mode, working fine. Recommend!
P.S. Root/Superuser needed

Try adding this line to your features.xml in the csc folder:
<CscFeature_Setting_CustNetworkSelMenu4>LTEONLY</CscFeature_Setting_CustNetworkSelMenu4>

[Q] Is it possible to force HSPA or HSPA+ and disable LTE?

G2 seems to have worse LTE reception compared to few other devices I had, is there anyway to disable LTE and go down to HSPA or HSPA+?
I know my area has terrible LTE coverage, but for some reason it sticks to LTE even if it means I am forced to 0.3mbps speeds! Ouch.

You can disable LTE from the service menu,use the code 5457#*(your phone model here)# And you will find an option there with the bands to do so.You can enable only the ones you want and dissable all others.Dont change anything else tho.I cant tell you exactly where you will find it cause the menu is slightly different for every variant it seems.

Thank you so much, I remember now people were running this trick on Nexus 4, but sadly it did not work. When you say Model here, I just put numbers only right? I got the D800 from AT&T, in dialer I just hit 5457#*800# and hit call, nothing happens, I get invalid MMI error. I tried 5457#800# no luck.
However, using your suggestion, I found the code to access service menu, but it wasn't as clear as I hoped it would be so I did not touch anything.
Code:
AT&T LG G2 D800 Service Menu: 3845#*800#
T-Mobile LG G2 D801 Service Menu: 3845#*801#
Verizon LG G2 VS980 Service Menu: 3845#*980#
Sprint LG G2 LS980 Service Menu: 3845#*980#
I expected on/off switches, but there is WDCMA-Only, LTE-Only, and nothing else. There is no HSPA or HSPA+ only or any switch, and I don't want to hit LTE only assuming that will limit the reception to LTE and I will get stuck with no coverage when there is no LTE.

On Sprint, I can go into data settings via dialer (##3282#), and edit LTE screen (requires service code). From there, I can disable LTE and force CDMA/EvDo. Of course, this is on Sprint variant, not sure how AT&T/T-Mobile does it or whichever carrier you're on.

I also tried *#*#4636#*#* which does not let me go into OEM-Info or any Radio selection.
Why does AT&T do this!?

I believe if you go into settings and go into the mobile networks menu, there is a menu that allows you to choose whether the phone will go into LTE if available or just stay on 4G HSPA+. I'm getting my G2 tomorrow, so I don't remember exactly how I did it when I played with it in the store. If you can't find it, I'll let you know what it is once I get my phone. This is with the T-Mobile G2.

In order of Nice to Naughty,
Sprint
T-Mobile
AT&T
Verizon (wayyyyy low in the list, naughtiest)
So, considering above, I am pretty sure A&T disabled that menu you are referring to (In Mobile Networks) some confirmed it working on Sprint, but I don't think it is available on AT&T. I am stuck with LTE.

Sorry, missed it earlier when you said you were on AT&T. Are you able to go to Settings > Tethering & networks > Mobile networks > Network mode? With the T-Mobile version, there's gsm/wcdma/lte auto, gsm/cdma auto, wcdma only, and gsm only selections under the Network Mode menu. That would really suck if they diabled that setting. I'm assuming you're on stock unrooted.

Go to LTE settings, modem setting, then select RAT then you can force what ever mode you want.

Switch network mode 2G/3G/4G (Tasker; without root) ?

Hi there.
Is there any way, to toggle network mode from 4G to 2G without root?
The problem is, that when im at work or at home, my 4G signal strenght is really weak, so it drains my battery too fast. When i manually switch to 2g, the signal strenght is good.
Is there any way without root to toggle network mode with tasker or other apps, while my smartphone is connected to my home or office wifi?
I tried AutoTools w/ tasker and changed the preferred_network_mode1 according to this tutorial, but it did not seem to work:
https://www.reddit.com/r/tasker/comments/6aif23/tip_change_network_type_2g_3g_without_root/
any help appreciated.

im on the international/european unbranded version.
yes, i do have that option but i would still like to use 4g, when not connected to my home/office wifi.

I hear ya, I'm on sprint which is a bit of a pain because it'll reboot phone when switched, try dialing *#*#info#*#* from dialer and you should be able to change network type from there on that model(yes I know not exactly what your looking for), but that's only thing I can think of without having to root or reboot phone each time(I don't own that model so I don't know that particular phones software)
