For those of us in Canada and some on AT&T that were fortunate enough to snag some LTE for their Nexus 4s, can anyone develop a nice toggle that allows us to flip between LTE and HSPA+/3G?
I guess all we need is something that can switch between the options of "WCDMA preferred" and "LTE/GSM/CDMA auto (PRL)" in the *#*#4636#*#* menu.
Can anyone take a shot at it or point me to the direction that can accomplish the same thing? Maybe use Tasker?
Thanks in advance.
Is the connection type when you boot the phone determined by the carrier or some kind of system setting? If it's a system setting, could a different kernel or editing a system file stop it from reverting back when you power down the phone?

There is already a build.prop edit method floating around that prevents a reboot from reverting back to HSPA+, but I'm more concerned with a toggle that flips LTE on and off.
The battery drain is pretty immense with LTE so I don't want it permanently on and would like to be able to flip it on and off when needed.

Certain things such as location based services dont work with the LTE,
im hoard 4sq and such so yea, it doesn't work properly
but i do enjoy the speeds
Tethering doesn't work with LTE enabled for me. Is this normal?
OP, couldn't you just use a 3G or HSPA only toggle to toggle LTE on and off?

That's a good idea, except I don't know if there is such thing as a 3G/HSPA toggle? I searched the Play Store and didn't find one.
just use the 'phone info' app to quickly switch LTE only or GSM auto PRL
those are my two settings i need only
i do have rogers APN ltemobile.apn in network settings, im on rogers
when i reboot it always uses that ltemobile.apn
it doesn't use the other default rogers one

The app is nice to bridge the inconvenience a little, but I would still prefer if there was something that could just one click LTE on and off. I assume this won't be something as simple as an app that could do this and would require some sort of coding or script that is out of my skill level.
Just hoping some crafty dev could come along and churn something out.
Thanks for the help though, the app definitely alleviates some of the hassle.

Right now, I'm using Notification Toggle, it can add a 4G toggle to your notification shade that sends you directly to the 4636 menu, after that, you still have to select the LTE option in that menu, but its better than nothing I guess.

Sorry if this has been asked, but searching for the word "4G" fails for some reason.
I use the Extended Controls widget, but the 4G toggle setting isn't supported on the Nexus (or perhaps for Verizon?), so is there a widget out there that will work with the VZW Nexus?
Thanks!
I found a 4g toggle bewteen SwitcherPro Widgets' toggles...
It says in the market that it doesn't work for LTE. What's up with that?
Might have to wait for a VZW specific ROM that has it in the pulldown menu.

Personally, I'd like something with Tasker/Locale features. Turn off LTE when the screen is off, turn on LTE when it's on...
That's what I have been looking for all day...lte off when screen off. Not that my screen has been of much so far...

Or 4G when screen is on, 3G when screen is off so you still get notifications. Also, an option to auto switch to 3G after the battery gets below a certain level would be nice.
Of course, even running 3G all day, my battery life stinks. I'm going to let it discharge overnight and see if that helps it condition a little.
Glad someone else thought of this
I agree with the idea of LTE being on/off with the screen...however, I would also like to see a toggle as well for times when I'm using the phone but not the internet.
I feel like switching between 4G and 3G that often would hurt your battery life (Keep having to find signal)

I agree. I think it would be a very poor solution. One of the most battery intensive tasks is searching for signal. Doing that every time you turn on and off your screen?
I had and an EVO 4G and now an EVO 3D (my buddy just got a GN LTE and is looking for a 4G toggle) and I've found the best way to preserve battery is to stay on 3G 90% of the time. If I'm about to download a bunch of apps or 3G is just going too damn slow, I quickly toggle on 4G and turn it off before I pocket the phone. Treating it as a "turbo mode" basically.
I don't know of a working toggle as of yet. If you wanted, you can manually change the setting under Settings > Mobile Networks > Network mode and changing it to "CDMA" only
Widgetsoid 2.0 has a 4g enable/disable widget but it says experimental and is greyed out. Hopefully something coming soon...
Have you tried juice defender (free version in market)? I don't live in a 4g area so my lte radio is always off, but hypothetically juice defender would auto toggle the 3g/4g radios.

I'm still searching for a 3g/4g toggle widget or something. I would also like to leave the 4g off except when I am downloading or browsing. My house is also just out of 4g's reach so It would also be nice to disable 4g when on wifi.
Has anyone found anything that works? It seems like it would be a very simple app to create.

2nd that. There is a 'toggle' called LTE Switch but it just takes you to the menu item, so it's not a true solution. But it gets us about 80% of the way there. I figure it's only a matter of time until Extended or Widgetsoid get a working toggle.

I leave my phone on 4g all the time and get ~13 hours. I tried only 3g and my battery life was significantly less. IMO there isn't a built in switch for a reason.
Hey all --
Is there an easy to way to toggle LTE? II'd like to have a quick option to choose LTE but not to leave it on all of the time since my battery dies like 3x as fast.
I know there's the menu option that is like four menus in and requires a reboot.
SETTINGS --> MORE SETTINGS --> MOBILE NETWORKS --> NETWORK MODE
I'm hoping there's a better way.
Thanks!

I will have to give that a shot. I have it installed on my SGS3 which is still unrooted at the moment. It at least has not Force Closed on me (like some of the reviewers complained about), but I have yet to find 4G. This is probably just do to the northern part of my area where I live missing coverage in quite a few spots.
I've decided to give this a shot. However, LTE is not available in my area so I will have no idea if it even works....

i'll give it a shot and report back. thanks for the suggestion!
I have every reason that it can be accomplished natively through the settings menu.
Because, if you dial ##3282# and you go through the menus (i forgot the exact one), but it allows you to switch between different modes, LTE being one of them, on the fly without the need to reboot. So I guess all I have to do is remove the reboot option from settings and it should switch the same way that it does in the ##3282# menu.
The app noted in this thread worked for me as far as taking me to the settings but it doesnt work like a toggle does. That being said there is no LTE here in Phoenix yet so I'm screwed either way LOL We have some regular spots of 4g but I dont believe this phone works on regular 4g, unless I'm wrong??? Anyone know?

Yea, I am having the same issue in the northern part of Dallas. LTE is not very good here yet either for Sprint, but hopefully if they sell enough phones and get enough complaints they will break out more towers faster.
Actually I have since uninstalled the App and since then I have not been able to locate LTE at all. I tried putting it back on in an area that I had previously attained 4G and still no go. I hope that Switch It did not mess with my antenna or some such. Just wanted to put the warning out there.

I don't have the SGSIII yet, since Sprint has not launched yet in my area, but I had a couple of questions.
Sounds like you are pretty knowledgeable, thanks for the info. When looking at the phone, I was surprised to see and didn't know the reason for the reboot when turning on LTE. Do you know the reason for the reboot? Is it anything logical or necessary?
I would hope that this will be something Dev's start building into their roms, unless of course there is a legitimate reason for the reboot.
Thanks!

The problem with that method -- which also requires your MSL code -- is that if you use it to select LTE, it forces the handset to LTE only without 1x or EVDO. They are mutually exclusive.
This can be used to bypass the normal settings that automatically upshift and downshift between LTE and CDMA data as a threshold function of signal strength, to force LTE. But it has the side effect of killing the voice/text connectivity.
I live in area that does not have 4 g so it stays off, however today at airport I tried and no 4G toggle anywhere! Where did it go, I swore when I got s3 I tested 4G but now it's gone? Thanks for help.

GS3 doent have a 4g "toggle" as you say...but you can make sure its enabled
settings-->more settings-->Mobile Network-->Network mode.
Preferred network mode should be set to "CDMA/LTE/EVDO"
If you have "CDMA/LTE/EVDO" enabled, anytime your in a Sprint LTE area your phone icon will switch from 3g to 4g.

it shouldnt chew up ure bttery at all, as all it does is search the network for 4gLTE and if it doesnt find it, it will automaticly go to sleep and try again like 2 or 3 hours later or periodically as it tells u. .however u do need to have sprint automatic connention left on in order for that work. atleast thats what i got from reading the sprint connection optimizer information it gave me.

The optimizer isn't for the LTE. I hate that garbage so I always leave it off. As long as your preferred network is set as stated above, it will automatically switch between them. Side note though, it may switch back to 3g if you don't have a very strong 4 g signal. It likes to be weird.

Do any of the custom ROMS have a toggle for 4g/3g? I live in a 4g area but sometimes the signal isn't strong enough so it goes to 3g. Quite annoying. It would be great to toggle 3g off and force 4g.
So I had s2 before s3, so I assume the s2 was a 4 -g wimax? It had a toggle widget.

Have you tried updating to the new radio? I believe they boosted the power to give slightly better LTE connectivity in those kinds of environments.
There is a way to force LTE on the GS3. I did it with mine so that I could map out the LTE zones with sensorly a bit easier while I was driving over the weekend. The way I was able to do this is you need to have Nova Launcher downloaded and installed.
Once you do this, long press on the home screen and go to "Shortcuts".
Next click on "Activities"
Next scroll down to "IOTHiddenMenu"
Then scroll down and click on "IOTHiddenMenu : HDR1X_Selection"
Doing this will allow you to force LTE only mode. Keep in mind you WILL NOT be able to make any phone calls while doing this. For some reason the GS3 requires the phone to be in LTE + CDMA + EVDO Mode to make calls even if you have a very strong LTE signal.
Another app I would recommend downloading is called OpenSignalMaps. Once you have the LTE only mode turned on or even the normal LTE + CDMA mode, you can use this app to refresh your network by clicking the little refresh button at the bottom left of the app in the Overview tab. What this does is pretty much turn your phones mobile networks on and off and then scan for LTE first before scanning for EVDO. I have been able to connect to many more LTE sites by doing this. Even ones that are fairly far away.
Hope this all helps. Let me know if you have any extra questions.

I am using Blazer ROM since I got the phone. Anyone having the same problem? It would be no big deal if the wifi radio didn't consume as much battery.
Not sure if Blazer rom has the option or not or if it would affect it turning back on, but is the Connections optimizer feature enabled?

I'm guessing "preferred network mode" will select the LTE preference or not. Connections optimizer only refers to WiFi in the help text.

Connections optimizer was rolled out to "ensure phones haves the best possible connection without affecting battery life" On older WiMax phones it also does affect 4G. It uses location data and saved WiFi IDs to know when to connect. Sprint likes it because it offloads data onto wifi/4G whenever possible.

Ah ok good to know. Though I should of probably rephrased my post since it was a reply to gotojanoo to let him know that it does not stop the phone from searching for a lte connection.
Right now I'm just using the stock att rom, rooted. At home I'm on Hspa+ and get great battery life, but when I travel to cities LTE I get the worst battery life. I can't even go a full day without the battery dying. Do any roms exist that allow me to turn off the lte radio and just stick with Hspa+? Don't really need any extra functionality over the stock rom besides this. I'm fairly happy with the stock rom and nova launcher.

Why do you want to turn it off ? If you are using data it doesn't matter the connection speed as far as usage goes (at least anything I use) as to how much data it consumes. I consume no more on LTE than I did on my 3G captivate with the same apps.

It only happens when I have lte. If I'm on anything lower battery life is wonderful. I'd think maybe its just poor reception and flip flopping between towers, but it drains no matter what part of town I'm in (Vegas) so that should rule that out.

This only works until you restart, right?

Using the *#2263# method does work until you restart. However, if you restart you will remain on the band that was chosen prior to restart. If you are on automatic you will have "normal" operations. If you choose 3G or 2G only bands you will remain. In order to change it you will have to dial *#197328640# first to access the menu again.
In regards to the APN, I have had problems with it giving me random network drops...complete network drops. There is another way to achieve this goal, but you will have to do it over again every time you turn on airplane mode or reboot. Create a new APN. You can name it whatever you want and fill in the APN name with whatever you want and save it. Fill out nothing else. Select the new APN created and exit. You will lose data for the moment. Wait 20 seconds after selecting the new APN and go into dialer and type *#*#4636#*#* and select "Device Information". Under "Set Preferred Network type:" you should see "WCDMA only". Click on it and select "GSM/CDMA auto (PRL)" and exit. Go back to you APNs and select the original one named "ATT Phone". After a few seconds you will notice the data is 4G only and not 4G LTE.

Hrmmm. LTE chews threw the battery faster but it downloads faster as well. There more involved in that drop than just LTE I doubt it the main culprit that and there are no know LTE off switches on any rom's.

The late antenna actually uses more power. So therefore yes. The main culprit is lte. At least until better antenna come out
