Has anyone out thought of a switch for root users on 4g phones to disable 3g so you don't have 2 wireless radios for 3g and 4g running at the same time? If so, can someone name the app, or tell me where I can find the info on it?

I think if you disable the 3g radio you would have no voice or text. Someone correct me if I'm wrong.

you're right. 4g is only for data.

I'm not sure this is correct. On the Thunderbolt, you can switch it to LTE only, and it remains able to make calls and send/receive texts. Although perhaps that doesn't disable the 3G radio.

Only reason this even came to my attention is because I had heard rumors about the Sprint users being able to disable their 3g radio and still receive texts and voicemails... So, I figured I would ask about it. I mean with dumbphones that weren't 3g how did those receive those functions without a 3g radio?
voice/text messages are on 1x while internet is on 3g/4g

Issue I see, is sometimes I'll lose 4g around here (GR area too), and if 3g was off, I wouldn't have data at all.

Than why when I'm on 3g, in a non 4g zone, when I go to make a call, the phone disables 3g?

@sheatyj - I would have use for this though because I travel the country for work... Most places I go are all 4g (or at least Verizon claims them to be) so if I can disable my 3g radio, I can make my phone last a little longer... Also It will help with me having issues with my phone jumping back into 3g when I just had 3 bars of 4g.
heard of a toggle on thunderbolt a widget
How about switch to turn off all but wifi?
A nice feature of my Blackberry was the ability to turn OFF the telephone and leave the WIFI turned ON. This was great for non-coverage areas and when I traveled internationally. Can this be done on the Bionic? tnx

Just enable Airplane Mode. That will turn everything off.
Once everything is off, just re-enable WiFi and/or Bluetooth if you want to use just that.
Hi,
I noticed at my work my Edge is stronger then my LTE but LTE works better and of course faster then Edge. I am asking if anyone knows how to force only GSM for calls and LTE for data. I go through the options and notice many settings but LTE is always "LTE AUTO" I also use the hidden menu *#*#4636#*#* and set LTE only or CDMA, LTE Unfortunately I am on Rogers and CDMA does not allow my calls to go through and LTE only is exactly that only LTE. Both those options work great but of course drop sporadically which I can live with except the no phone part. What is the point of having a phone if you have no phone reception working on your phone.....
So my question is simple, is there a way to have only GSM and LTE set up or at least GSM and 3G/4G but with out the E network which ever that is.
Thanks
JB
No one?

Are there any Mods to keep LTE active in low reception area.

You could force LTE only, but then when the reception drops off, you'll have zero cell service.
It would be nice if there were more options offered for preferred networks. I leave mine on WCDMA preferred, and just do without LTE until I want/need it.
Guide: How to turn LTE off
Turning LTE OFF can be very beneficial to the end user. Turning LTE off can boost your signal and save battery life in areas of weak LTE signal strength. HSPA+ and EDGE signals travel further than LTE signals. At the time of this writing, AT&T’s HSPA+ network performs very, very well. Most people have switched to LTE. It is very easy to pull 10mbps down on HSPA+. Therefore, if LTE is congested you can try out HSPA+ (AT&T calls this 4G). Some people also like to force the device to LTE only; this way they don't get calls, but can receive texts.
1. Open dialer
2. Dial *#*#4636#*#*
3. Device information
4. Scroll down and then choose your preferred network type:
WCDMA Preferred = Your phone will prefer UMTS/HSPA or HSPA+. Will connect to EDGE if it has to. NO LTE.
GSM Only = If selected, your phone will only connect to EDGE (2G). You will be able to call, text, and use slow data.
WCDMA Only = UMTS/HSPA+ only. No EDGE, or LTE whatsoever
GSM/CDMA Auto= Will connect to either UMTS/HSPA/HSPA+ or EDGE (which ever one is available)
LTE/CDMA Auto = Will only connect to LTE and UMTS/HSPA/HSPA+, NO EDGE
LTE/GSM/CDMA Auto = Will connect to LTE, EDGE, or UMTS/HSPA/HSPA+
LTE/GSM Auto = DEAFAULT SETTING
LTE Only = You will only have LTE. You cannot make calls under this setting. Good for those who want data and text capabilities.
Hope this helps!!!

Will the change last through a reboot or does it need to be changed every time the phone is restarted?

Yes. For each reboot you'll have to repeat the above steps. However, I would rather do this, than have to take out the sim each time.

I wonder if a NFC task program can be used to program the sequence into a NFC tag so it can be easily changed each time?

That I don't know.
Thanks! I switched from the default to WCDMA preferred and seem to have a better signal where I live (on a mountain).

Sorry if this is a stupid question but I don't want to screw up my phone. Which would be the default in case I want to turn LTE back on?

You will not screw your phone up, no matter which setting you choose. LTE/GSM Auto is the default setting. Once you select your preferred network it will not stick once you reboot your device anyway.
Which one is the best?

Probably leaving it on automatic.
isn't there a toggle switch or a widget that you can download from play store to do he same thing? just wondering

Cannot turn off LTE with above instructions
When I try to follow the instructions, I dial the number and a pop-up appears with "USSD Code Running..." then it closes and a new pop-up appears saying "connection problem or invalid MMI code". I have tried to make this call from various areas with better connections than in my house, but still to no avail. I'd really like to disable the LTE because it is only strong enough to constantly force changes from 4G to LTE and back while massively draining my battery in the process. Any advice?
I upgraded from S3 to S5... In Out location there is one LTE tower.
When at office which is bit far from LTE tower, It only connects to LTE and due to congestion i always get 0.2 mbps only..
But When i had S3, it will switch automatically to 4G(HSPA+) at office and at home or shopping it connects to LTE.
So I called ATT support and they said its due to network congestion and they switched to 4G on their side.
So now its always shows 4G only no LTE but speed are good like 8 to 10 mbps..
I tried the steps in post1 and it shows WCDMA preferred... Is this what they modified remotely?
Try Intelli3G everyone, you have to install Xposed framework and then install it but this app is amazing for convenience.
I tried changing to LTE option its not allowing. I can change to other options other than LTE.
Any idea.. Is it controlled by AT&T?
I called ATT and asked them to change it to LTE.
Now I can change the settings as needed.
So if ATT sets to 4G, you wont be able to switch to LTE.
Is this the only way to change the preferred network mode on SAMSUNG-SM-G900A, ie. by going to details mentioned under #2
Has anyone tried this lately? I know the old 4636 code worked on older galaxies buy I can't get my G900a to respond. Still on 4.4.2
Work fine here on 4.4.2 and 5.0

Hi, I realized that when I turn off the 4G network data the phone changes to 3G, then if I turn on data again it turns 4G on after 20 seconds.
I had tried to use the *#*#4636#*#* method and put "LTE only", it works, but after I turn off data again the setting returns to GSM.
Other phones have 4G network ON don't matter if data is on or off.
There's a way to force 4G network all the time like the other phones have?
Well, like no one has the answer, I had found a workaround:
The app Intelli3g is the answer!
I live in hilly country where LTE is available on the hilltops, but signal often drops to HSPA or 3g in valleys. My concern is that I will be wasting power while the phone is on 3g and searching for LTE. I don't know if this is a problem on the note, but it is on other phones and I am looking for an EASY way to stay on 3g when not using data. Any solutions?
*#*#4636#*#*
Device information then you can force it to any setting you want. You'll want WCDMA only for 3G only.
Thanks. If I get confused can I back out of this code menu or just restart the phone to return to default LTE operation? Don't want to screw up and get trapped in an unwanted mode.
