How to enable 4G-only option in Android settings

A few years ago, I used Setting Database Editor application to enable LTE only on my Huawei Mate 10. After upgrading my cell phone to EMUI 12 (Based on Android 11) this application couldn’t help me to enable LTE only anymore so I decided to find a new solution and when I couldn’t find a new solution, I totally forgot about that. (also, this open-source fork of SetEdit does not work for this purpose)

Today I searched about a solution again, and I found a great solution and used ADB debugger to enable LTE only option in phone setting and here is how:

ADB on Mac

easy 🙂

brew install --cask android-platform-tools

Enable developer options in Android settings

Go to “About” in your samrtphone and click on “Build Number” several times and after it has been enable, go back to setting home page.

Go to developer options and enable USB debugger and ADB over USB options.

then connect you phone to your computer (Mac/PC)

Enable LTE only

First check if your smartphone is connected

adb devices

## result:
# List of devices attached
# QMU7███████03279	device

If you can see any device listed after running above command, congrates, you devices is connected and you can continue. then run following commands one-by-one:

adb shell settings put system hw_networkmode_preference 11
adb reboot

Your phone will be rebooted and now you have a “LTE” option in you Network preference settings.

Enjoy and thanks this guy
