Just watched a YouTube demo and the guy mentioned pulling the SIM card being the only way to turn off LTE/4G. I know there have been many questions posed and didn't see this mentioned so figured I'd put it out there.

I feel like I just have to ask... why would you want to turn off 4G? if you have no 4G in your service area, the phone already automatically switch down to 3G

To minimize battery drain when you're not needing/using data? I guess you could leech wifi as often as possible too but know many people have asked about disabling 4G, I can only assume its power consumption related.
Don't pull out the SIM card. What happen if you loose it? You'll be ended up by paying additional charge for replacing new sim card.
The good way to disable 4G is just type:
*#*#4636#*#* when you want to make call.
Then, scroll down until you see the word says "CDMA + LTE/EvDo".
Click that and change it to "CDMA PRL Auto".
If you want to use 4G, just do the steps above, and instead of "CDMA PRL Auto", change it to "CDMA + LTE/EvDo" (you can also change to "LTE mode" if you want 4G only).
Hopefully, it will help you

You can "automate" this is a way by downloading an app called "Phone Info" by [email protected] It allows you to enable/disable 4G. Basically does exactly what dialing would do but is faster and easier.

Thanks for the link. My app drawer's cluttered enough with apps, though; maybe after we get root and can remove all the bloat/crap-ware.
I usually just add a contact with all the dialer codes so I don't have to memorize them. I'm in a 4G area, so don't really see the need for this personally, but nice to know the trick anyways.

I used to have the same issue with a cluttered app drawer (I'd uninstall apps I used occasionally just to shrink my app drawer). I started using ADW Launcher EX a while back and it lets you make different app drawer versions. Basically you can choose which apps show up in the app drawer, so you can hide all the bloatware icons and leave the apps you use all the time. Then when you want one of your rarely used apps, just switch to the "ALL" app drawer and it will show every app installed on your phone. Just a suggestion, I found it to be really helpful.

That's an excellent tip! Thanks. I'm actually a licensed paid for version of ADW Ex, but haven't used it in a while, preferring the look and feel of Launcher Pro instead. Might be time to check out ADW again...

I'll use my phone as I see fit, and if I want to save some battery by disabling 4G? Well then, I appreciate the people in this thread who provided that information.
Thanks!

Until a toggle switch comes out, this may be the only way. But who would want to go back to 3G?

So, what's the way to use Thunderbolt in overseas CDMA networks that doesn't offer 4G LTE service.
Is manual PRL programming (mean ##DIAG mode) or R-UIM card possible solution for this problem?
If you use LauncherPro you can create an Activity to go directly to the phoneinfo screen. I use this all the time to turn off 3G on my Droid1 when I'm at work thanks to no 3g at all.
Long press the home screen, add shortcut, then Activities. Select Settings and scroll down for what seems for ever until you see Phone info and select it.

Or use Any Cut from the market if you dont use a custom launcher.
also jcase linked a program he whipped together in the theme and apps thread
My current combination of cyanogenmatt, sonygenmod with fserve kernel has decent battery but 3g seems to remove every bit of juice in any rom..was wondering if by any way 3g drain could be removed at least slightly reduced
Thanks in advance !

3G is a battery eater, that's a given in any smartphone. Your options are:
- turn data off when you're not using;
- use only 2G unless you're downloading; or
- get a battery-saving app from Market to smartly turn data on and off in intervals
I use JuiceDefender to turn 3g off when I lock my phone
okay guys!!understood ther can be no magical way except using a battery saving app thanks for your reply!
I had the same problem but found some interesting tips in this thread:
http://forum.xda-developers.com/showthread.php?t=1189755
The specific one that I think applies to this matter is this one
2. Use "GSM auto (PRL) to save more juice while still connecting through 3G
- in the phone setting>wireless and network>MobileNetwork>NetworkMode
we are only allow to choose GSM only/ WCDMA / Auto between two
- but if you use type "*#*#4636#*#*" to phone Information, you can choose more type of networkmode. It is claimed that choose "GSM auto (PRL)" allow you to save more battery (cell standby) while allow you to connect to 3G network.
- This might somehow depend on your carrier / provider
- Please provide feedback on this. THanks

It really worked for me: went from 7-8 hs of battery life to 14-16 hs
Does "*#*#4636#*#*" work on Optimus one? I entered with dial pad but nothing happen.

Hey Guys,
Ever since I switched from the original branded Three UK ROM, I've had basically no internet access at all on my phone.
Everything else works flawlessly, except I can't get internet connectivity.
I installed one of the "pre-rooted" roms from the forum a few days ago (unbranded UK Rom) and the issue still exists regardless of what APN settings I use or how I go about enabling/disabling the connection.
The phone simply dosen't show any kind of GPRS/3G signal on the status bar and only shows the standard phone signal with a little "R" above it. I've tried literally everything (going to the power menu, enabling/disabling data, etc). I've tried various APN settings posted on forums, but nothing works.
What else could cause this? The thing that is frustrating is that the internet previously worked on the phone.
Cheers,
David
Sounds to me like your phone is on national roaming..untick the box in mobile network settings, i to am on 3 uk and have never had any problems, are you 100% your apn`s are right ..let us know if you need check them with mine.
it does sound to me like we will have to step by step your settings to make sure there same as mine ie...know working.
Thanks for the reply lodger, where do you enable/disable national roaming on the phone?
Can you post all your settings so I can check against mine.
Thanks for the help

Have you tried flashing a different modem? Try NELP3 (Flash via CMW)
I really need some assistance ASAP on this one, folks. My phone/text is not working at all ever since I did the following stupidly today.
I tried to see if there was an option to get 2G/3G/4G working on the VS985 on 7.0. Guess I shouldn't have been so curious.
The only real steps I took to see was going to: Settings>Fulmics Tweaks>Advanced>Hidden Menu>Modem Protocol>Changed to Automatic..........now I have NO talk/text. Only 4G LTE data. Does anyone know what I'm referring to here? How do I get back to the original settings which worked fine!?
There must be a way out of this mess.
EDIT: there is! seemingly random combo led me to a solution.
Under the phone settings for mobile network - network mode: select CDMA+LTE/EVDO, and under the access point names: use VZWINTERNET. Make sure both of those are also the same in the hidden menu as well as selecting AUTO under Modem Protocol. That seemed to fix it for me.
Mods can close this one up.

So far, so good. I haven't been to any areas with 3G coverage, but I hope to have that working as well now. I'm traveling halfway around the US this week, so it should make for a good test. Also installed Greenify - does voodoo magic for the battery life.

Thanks! If the combo above doesn't work, you can also try auto under the hidden menu frequency, and auto (or global) in the phone APN settings if LTE/CDMA don't give you a good signal or only give you data but not voice. For some reason the phone APN settings may look different depending on what you have previously selected or when you reboot. The access point should always be VZWINTERNET and you should not change any of those values in either the hidden menu or the phone network menu.
Once you get it figured out, you should not have any further issues or need to tweak these values unless traveling internationally. If that is the case, check the LTE bands carefully 1st and adjust frequency 2nd.
I'd be extremely cautious about changing any of these values. If you make any mistakes, recovering can be a slow process as these are system level changes that will impact the phone - no matter what version of android, rom or nandroid backups you had previously - cannot override these changes. Also, screenshots won't help because the changes in the hidden menu aren't reflected in the UI.

Thank you again kind sir. Safe travels.
this working only werizon area?
Hello fellow Note8 and Tasker users. I'm huge fan of both and usually have lots of questions on how to accomplish things in Tasker. Some of those things are device specific, so I thought a thread here may be handy.
Let me start with this: does anyone know how to use Tasker to activate PowerSave mode? I'm a teacher and I'd love to have this active when I'm teaching (then turn that off during my lunch break/plan period). Is there a certain intent I'd have to send? Or is it simpler?
Also, without root, I cannot turn on/off mobile data or adjust GPS settings...
Any workaround that you guys know of?
Here you go: https://www.reddit.com/r/tasker/comments/4zsi0e/project_share_toggle_settings_eg_location_mobile/
In case Tasker can't help you, I am doing everything you have mentioned using Bixby Voice. Just set up the Quick Actions and assign a voice prompt to it.

That's actually really cool and I didn't know it could do that. The beauty of Tasker however is that it's automated. I don't even have to think about it. I step into work and my phone is on Powersave mode with no mobile data connection or Wi-Fi (while I teach). I get in my car and my GPS is in high accuracy mode. I go in the library and my phone is on silent. I go to a house I'm tutoring in and my calculator app is already pulled up. It's a thing of beauty!
Okay so it turns out the method linked earlier is already "prepackaged" so to speak: it's included in Auto Tools! I already had that app and didn't even know it could do this. So you still need to use ADB to grant it the proper permissions but it will save you the effort of getting the app factory and importing the xml file and exporting the app.
I'm excited to see if I can toggle mobile data this way! It seems to be hit or miss for different devices. Anyone tried on their Note 8?

I have been reading over this for a while. I was wondering if this would allow for toggling on and off wifi hotspot? I've been trying, but I read something regarding Nougat and how the name/service or something was changed.
I have no problem toggling it off and on using the quick tiles, but I have an Android car unit that I use my Hotspot for.
This worked on my older phones, being able to stick an NFC tag to my phone mount in the car to toggle the Hotspot on when placed in it. Or having the Hotspot start/stop when connecting or disconnecting from the unit's Bluetooth.
Thank you for any help in advance.
@wigglitz I'm not sure how to toggle Hotspot, at least didn't find anything related on System-, Global or Secure Settings.
If you are using Toggle Setting method linked before, here is how you can find what you can change:
These commands will show you list of available settings with current values
Code:
adb shell settings list secure
adb shell settings list global
adb shell settings list system
Now, if you are unsure if some setting is what you think it to be, I'll give you an example how to check it.
Let say by using command adb shell settings list secure you find setting install_non_market_apps
Now if you are unsure if that is the one toggling Unknows sources on/off, do this:
Toggle Unknows sources off from settings, then type:
Code:
adb shell settings get secure install_non_market_apps
This will return 0 (because you set if off)
Toggle it back on from settings and run same command, now it will return 1
Now you can be pretty sure that's the one and will be able to make task to automatically allow installing apps from unknown sources when opening Substratum (for example)

Look into Auto Tools (Tasker plugin). That's what I'm using instead. There's definitely an option to toggle hotspot. There's literally hundreds of settings to tinker with, but my understanding is that the success of the individual options depends on the phone model.
I'm testing to see if I can toggle mobile data on the Note 8 and if time, I can test wifi hotspot too. :good:
GOOD NEWS!!!
Mobile data CAN be enabled/disabled without root on the Snapdragon model!!
Use the app Auto Tools with Tasker, give the appropriate permissions with ADB, and it works beautifully!! I'm so happy. ???
GPS works too - I can change it from battery saver to high accuracy and back at will.
I used to disable Mobile data, but now I leave it ON all the time. When you connect to wifi it's not in use so why to even bother turning it off? When I'am not on Wifi it's on. What I'am thinking of doing to save more battery is switch to 2G when connected to wifi, my 3GB/4GB signal strength is not so good. Should save a lot of battery when at home.

I am a teacher. The wifi signal in my building isn't great plus I don't need it anyway when I teach. I turn off pretty much everything during the times I teach. I have Tasker turn Wi-Fi back on for my lunch/plan period and turn off powersave mode. I used to lose 30%+ a day at work while not even touching my phone (awful signal primarily). I'm hoping this helps me keep it to 10% or less lost. I'll report back!

Turning wifi is a must if you leave it on it will always scan for new wifi and drain battery. I use signal towers to turn it on when at home and off when not, works rly good and no battery drain.
