Disable 2G (LTE/UMTS only) solution

Sometimes the phone jump to 2G (EDGE) for no reason while HSPA and LTE work perfectly.
Here is the solution (and it will stay after power cycle):
Dial *#*#4636#*#*
Phone Information
Scroll down to network mode and choose "LTE/WCDMA"
Reboot the phone immediately.
This method works for me.
Almost, its *#*#4636#*#*
Trying to do this on my D855 international G3, on lollipop, but can't get into the phone information .
*#*#4636#*#* works, but when I click on Phone Information, an error is given 'note this application does not work on this device' . I suspect a changed lollipop radio/Rom thing.
Any idea on how to achieve this another way?

Did you manage to fix it?
is there a solution for this on asop (euphoria 7/06)?.... after a call it goes to 2g and it "never" switches back to lte
New method:
Dial 277634#*# and you can get in Hidden Menu -> RAT Selection.
Typing 3856#*855# into the dialer allowed be in, then choose LTE, then RAT options.
Using the G3 D850 (AT&T) for t-mobile but it rarely conects to 4G LTE, it's usually on 2G, tried doing the above, with the *#*#4636#*#* code came up a error that I can't access that app, and in the hidden menu I couldnt find where/how to set WCDMA or LTE only, any new way to do this?
Qwerty when in hidden menu choose LTE-ONLY > then >modem setting> then > rat selection works on my g3

Missing Option "Enhanced 4G LTE mode" [THREE UK]

Hi,
I am on Three UK and I do not see the "Enhanced 4G LTE mode" option under Mobile Network Settings. Any idea what might be causing this?
I am rooted and on stock OOS 3.2.1.
I understand that this might be related to an existing/similar issue.... (not sure though!)
Thanks,
I have the same issue no "Enhanced 4G LTE mode" using Rogers Network in Canada. Anyone knows why . Just updated to nougat...Still no "Enhanced 4G LTE mode". When accessing advanced mode via *#*#4636#*#* I see a place where I can toggle "volte provisioned" but everytime I exit the program the setting reverts back to disabled. Any help would be gratefully appreciated. OnePlus 3T user
Could someone explain what exactly is enhanced 4G mode? I'm on 3 UK but I've never heard it. Many thanks

Were you able to figure it out? The setting is also missing for me. I tried OP3, HTC 10, and Nexus 6p. The VoLTE provisioned flag acts the same way you describe.

How to set network mode to 4G only?

Please help.. Is there a way to set network mode to 4G only or LTE only?... In settings, I only have the Autoconnect, 2G only and 3G only options.. Thanks..
Is your SIM card already 4G supported? What's your carrier?
The 4G auto connect is available? Apps might be able to access 4636 without root. In there, if there's an option, select phone information, then lock the RAT to 4G only. Alternatively, if *#2263# or *#2683662# is available, in *#0011# select the other SIM if there is any, then in those other codes, band selection, GSM ALL (for the unused SIM), change SIM again with *#0011#, band selection, LTE ALL(for the used SIM). What's expected: If the SIM is not a USIM, the RAT will stay on 3G(UMTS/WCDMA). If the USIM is not authorized, no signal. With soft PLMN locking (manual operator search) the signal level is shown but it's unusable. If the signal is still not available, maybe the phone does not support that band/frequency or no LTE coverage? If rooted it's possible to add LTE only in those settings in feature.xml, if that file is not available others.xml is used. Or launch 4636, or RIL service mode with am broadcast.
Use this app (no root needed). Set to LTE ONLY. Works fine.

This is worth a try. It's 4636.
ADD THIS IN system\csc\other.xml
<CscFeature_Setting_CustNetworkSelMenu4>LTEONLY</CscFeature_Setting_CustNetworkSelMenu4>

Force / Lock LTE band

I am on a stock rom, rooted with Magisk.
Is there a way to force and lock myself on an LTE band?
I use to be able to do so with the network signal guru app, but I guess sprint or the phone took and update that no longer works.
Will running a custom rom enable this option?
I tried *#*#3282#*#* on the Dialer, entered 000000 as the MSL, and it just takes me back to the Dialer. Cannot get into this diag mode.
/anyone on a custom rom can try entering *#*#3282#*#* and let me. Know if you can access the LTE menu?
++ I am on Sprint service if it matters
Anyone?
You need to go into "Radio Info" and set the "Set Preferred Network Type" to "LTE only". This is the only way I know how to (on 9/Pie). warning: but this does not save/survive a reboot...
I personally use a specific app called "Network Switch" to gain access to the "secret menu", but I can't tell who the developer is and it doesn't seem to show up on my Play Store -- in other words, it may have been a very random site where I obtained the app. There is also a manual way to get into the menu by using custom shortcut apps to access "com.android.settings/com.android.settings.RadioInfo" (I personally use QuickShortcutMaker)...
Good luck and hope this helps...

Thank you, but instead of forcing to LTE only, I'm looking to manually select force the LTE band (disable band 26 and 41, only allowing band 25LTE)
Cna your app do that?
