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.

Nice
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.

Would you have by any chance the line for the built.prop to stick the setting to GSM Auto (PRL)?
TIA!

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] Mobile network issues [SPH-L720]

I have been having substantial problems with my Spring GS4 connecting to mobile networks. I am in an area where I should have LTE, but most of the time my device constantly switches between 1xRTT and eHRPD (and NO network connection). Occasionally it will connect to the mobile networks 3G on 1X and 4G on LTE, but that usually requires restarting the device/ turning on/off airplane mode.
Any thoughts that you have would be greatly appreciated. I am happy to supply additional information upon request.

When you say 'should' have lte, do you mean Sprint had officially announced lte live in your area?
If not it's likely your issues are associated with lte deployment and are fairly common until upgrades are finished.
If so, if try prl and profile update

My area has an active LTE tower. I sometimes do connect, but soon after it goes back to no data.
I have tried a prl and profile update, although I will try again right now
Update: I did a prl update, but the profile didn't work (my device won't stay connected long enough for it to finish. Multiple attempts)

So what do you mean there is 1 tower in your area that has LTE? If that's the case it will be a while to get a consistent stable LTE connection because they would be doing NV upgrades in your area. And how far are you exactly from the tower that has LTE. It is probably just out of range or can't penetrate the walls or something. You should probably just go to s4gru.com and find your market thread and read. Also are you on a custom ROM. We can't really help without more info.

try a ##72786# reset(may need msl/spc) to reprovision your data profiles. I'd suggest being on wifi before you do this so that the profiles update over wifi after the reset. Do your PRL update over wifi as well.
It's possible that Sprint is in an upgrade phase which is causing issues. Here in philly we have many LTE towers yet my connection with eHRPD/LTE SUCKS!!! I know what bad is... this is worse than that.
You can get around this(YMMV) by setting the mobile network to cdma(cdma/evdo) instead of cdma/lte(cdma/evdo/lte) in settings. Doing this will make your phone ignore eHRPD/LTE and just stay on EVDO.

I read that ##72786# really screws up this phone on another thread
OP If you have NV upgrades going on in your area, give up on depending on your phone. I had to switch to Google voice just so I could find out if someone tried calling me because I would miss everyone's calls in addition to having almost no Internet.

That code should work just make sure your on cdma/3g only

Update: I connect well to LTE, but whenever it is eHRPD I lose connection. 1x works find, as does EvDo. Let me know if you need any more info.

Thanks for the replies u guys. Im guessing that in my case its an upgrade phase. I still get connections all over but it switches back to EVDO all the time. Ill keep u guys updated.
Update: been plugging in at different locations and lte is connecting. When I unplug shortly after back on evdo 3g. Does anybody think power management on a system level might be a culprit? Anybody having similar results?

2 Devices. One seems to connect to LTE better than the other. Same Place, Same Tower. One is stuck on 3g (or worse) as you detail above while the other is solid 4g. Data on/off cycle doesn't help. I was using RF Signal tracker to see tower, and network information. I have also had many dropped calls, as well as Bluetooth troubles.

Unable to use data during a call?

I have N9005 in the UK on EE network. We have 3g, H+ and LTE 4g. In my area I don't get LTE so that os irrelevant.
When I make a call, sometimes I can use data on the phone. For example, whilst on speaker phone, browse XDA.
However, very often, I have no data at all during the call. No 3g, no H+.
The problem is not data signal, as when the call ends I can easily use data.
So, does anybody have this issue?
Also, can anyone explain why?
F. Y. I it is GSM in the UK.

if you have a data signal while on a call your in a H+ area anything lower the data signal drops for the call

yep basically only a H+ signal supports voice and data together. i had it since sgs2 just sort of learnt to put up with it

My understanding has always been that only Three network could use data during a call. Unless I'm wrong.

does your wireless carrier support phone call and data usage simultaneously. You probably need to call your wireless carrier and find out. Goodluck

YOU don't get LTE because N9005XXUDMJ6 firmware
My one is same, wait for N9005XXUDMK2 firmware or just make clean instal with odin v3.09,Then you will get 4g/lte,
Yesterday i had same issue with calls,,when i make call or receive call data signal was gone its all related to N9005XXUDMJ6 firmware Just install N9005XXUDMK2 then everything will be fine....

phone just stop receiving any call but the signal bars are full

Anyone experienced that the phone just stop receiving any call at all but the signal bars are full?

I read these but it mentioned N5 only,
but I did experienced this problem couples of time in different days and it last for so long that I didn't know at all
(only found out when someone did leave me voice mail and it popup)
I am using 4.4.2 rom with hybrid modem LTE enabled,
I am trying with LTE disabled right now and see if the issue fixed.

If you dial *#*#4636#*#* it'll bring up a menu. Click phone information and make sure if you wanna use LTE make the selection to LTE/GSM auto not LTE Only. I've has that problem and i could receive calls or texts. If you wanna go back to HSPA+ use WCDMA Preferred. Hoped that helped

I use LTE/GSM auto already and this still occurs.
I am turning LTE off right now cox missing calls is more serious than having higher speed

It could be your radio, hopefully switching to use LTE every time you want to use it isn't that much of a pain

Problem with LTE

Hello!
I have a problem with LTE in my device. When I have it in 3G mode internet works ok (but it's 3G). When i have it in LTE/3G mode first it connects to 3G, next it tries to connect to LTE but fails and it's out of reach for few seconds, and then gets back to 3G. I figured out that it isn't SIM card issue (it works with other devices). I also checked that this phone supports 4G bands in my country. Is there any way to fix it?

Check your apns you may need change or make new one.
