Switch network mode 2G/3G/4G (Tasker; without root) ? - Samsung Galaxy S8 Questions and Answers

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:

any help appreciated.
cheers

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)

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>

Force LTE?

Sometimes I drop to 3G in my home 4G area. Turning the phone off and back on usually does the trick but is there another way to keep the 4G connection?

I believe you can set the phone to only receive CDMA and LTE in the Mobile Networks option of the settings (in the more section)
You can also set it to receive only GSM, GSM and CDMA, or all available networks.

CDMA=3G, LTE=4G. Right? Since I am on the Verizon network, the only circumstances that I would connect to GSM is if I left the USA, right? I wonder if there's a way to isolate LTE connectivity and turn off 3G all together..

You on stock or a custom ROM?
That sounds like a radio problem tbh.
You can't use LTE only - in fact, LTE requires a CDMA or GSM base for stuff like phone calls so it always has to be connected to 3g or 1x.
There's a possibility that switching airplane mode or pulling your SIM out would force LTE to reconnect
Solution: Yes you can force lte
I'm not a engineer or a radio analyst but I do believe what the previous post says about LTE needing CDMA is completely wrong - it certainly doesn't need to have CDMA or any other radio band to effect LTE. That being said, LTE is BASED off of 3G CDMA. But again, I may be inaccurate, however I think the "proof is in the pudding"......HOW TO FORCE TO LTE (ONLY)
1. Open up your phones dial pad
2. Dial *#*#4636#*#* (An app with the title "Testing" should open automatically... but not 100% sure. If it doesn't open auto hit dial....
3. Select "Phone Information"
4. Scroll down the phone information page, you should see the first button that says "Turn off radio"..... We want to focus on the item right above that. By default it's set to "LTE/CDMA/EvDo/GSM/WCDMA"
5. Click on that which should provide a drop down list, with specific radio bands.
6. In your case select "LTE Only"
7. Profit!
FYI: IN "LTE Only" mode you will not be able to make or receive calls - this is good for DATA only. You can manually reset back to default mode but regardless every time your phone reboots it will go back to default.
Well yeah that's true. Not really sure if vzw will let you connect though. But yeah no calls or text

Network coverage issues or device ?

I'm having some problems with my G2 - I don't have good 3G coverage especially inside and my phone keeps dropping calls when on 3G. It seems the software doesn't reconnect that fast and doesn't switch to 2G when the 3G signal is too low. Is there any way to change the preferred network and stop the device being so agressive at keeping 3G connection?
Settings/networks/tethering & networks/mobile networks/network mode/GSM only.
I already know that. It is the most unhelpful advice to give. I have to constantly go into settings and change that? No way. It isn't in the notification toggles which is really odd. Any idea how to add it? I feel my G2 has some radio issues.

Well if you're going to be like that then there's no wonder why there aren't a stream of responses on here with people trying to help you out.
Just remember, you're the one with the problem, so you may want to be a little nicer to those that try to give you help.
I'm sorry about that, but there wasn't a stream of responses in the first place. He was just stating the obvious, and the obvious is that the G2 doesn,t have a shortcut to switch between 2g and 3g. I'm just trying to figure out a way to do that, but all the apps that claim to do that and they are too many of them, just don't work. I'm thankful for any help, don't get me wrong.

There isn't a solution as simple as hitting a switch, but you can try the following:
Go into your Dialer and tap in *#*#4636#*#*
This will take you into the Testing Menu
Select 'Phone Information'
Then about half way down you will have a drop down where you can "Set preferred network type:"
This will allow you to choose whether to use 2G or 3G, but more important to your case you can choose how it will react if signal strength is low.
You probably want to select something like "GSM auto (PRL)"
Bare in mind though that this option will reset itself back to original setting each time you reboot the device.
Now I don't know if this will solve your problem, but it is worth testing out.
Here's a list detailing the main available options:
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best.
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this
Wnderful setting.. amazing speed... performance of handset increased like rocket..
Thanks a lot...
Hi,
After dialing *#*#4636#*#*, it shows up the menu.
But i am not able to select Phone Information option. It says "This application does not work on this device".
Phone info: LG G2 D802 - Rooted - PowerG2 2.1 ROM.
I face frequent network signal drop, I tried CloudyG2 ROM also.
Thanks !

4g / LTE Toggle / radio control

At work the 4g LTE signal for ATT is very poor in the building, but we have 4g repeaters for ATT to fix this issue. Unfortunately, phones are stubborn and like to stay on 4g LTE despite having 1 bar of signal vs full signal with 4g. I had this same issue on my iphone 5 but was able to easily force off LTE while i was at work and have a steady, reliable data connection. My Note 4 seems to have the same affinity to wanting to be on 1 bar of LTE, but I cannot figure out a way to toggle / force LTE off and just use 4g. Anyone have any ideas? Anyone know of an application I can use to resolve this issue?
Thanks
try settings...more networks...mobile networks....network mode....It should be in there..I have the sprint model so I don't know for sure...but that is where mine is....hope this helps

Unfortunately, there is no option for Network mode on the ATT version. I wonder if this has to do with voLTE....
I did find a backway to the network mode via *#*#4636#*#* but I am unsure of what I should be setting to "disable" lte while I'm in the building at work.
I think I've sorted this out now. If I change LTE/GSM AUTO to WCDMA preferred it seems to immediately switch and hold onto 4G. I do have to change it back. Maybe I will write something so I can quick toggle this since nothing on the app store seems to work.
hi,
If you are rooted ? You can use an xpose module called Intelli3G
I use it on my phone ,works 100% and switches smoothly/fast between eg 4G..3G automatic
eg if my data is of its on 3G as soon as i switch data on /wifi it changes to 4 G
For interest sake ,here is a link to market ,you can read desciption what it does ?

good luck

Phone not switching back to 4G

Hello,
I am a new one plus owner and noticed that when 4g connection is lost it switches back to (H+ or 3g) which is normal. But when I go outside again I have to manually enter airplane mode and disable it to gain 4G again in the heart of Amsterdam.
I am currently running 9.0.11. Do some of you notice similar problems as my old phone works fine.
Open Phone app and dial *#*#4636#"#* goto Phone information. Make sure that Preferred Network type is set to LTE/UMTS auto (PRI). If it still does not work try switching the modem using QPST tools.

Set preferred network type.
LTE only
Hope it helps
Hi Isene, Did you get this problem resolved? I'm having a simular problem of a dropped 4g connection which won't reconnect. I'm on Tele2.
I tried switching the preferred network but that didn't work.
