Android Volume Steps

Warning

This is a rather old guide and may or may not work with modern versions of Android.

Connect through ADB

1. Boot into TWRP
2. Connect device to computer
3. Terminal: List devices with adb devices
4. TWRP: Mount > System

Get and edit props file

1. Terminal:

# Android <= 9
adb pull /system/build.prop

# Android 10 - 11
adb pull /system/default.prop

# Android >= 12
adb pull /default.prop

2. Editor: Add the following settings to the pulled file

ro.config.vc_call_vol_steps=14
ro.config.media_vol_steps=30

Push props file

1. Terminal: Push file back to the device

# Android <= 9
adb push build.prop /system/

# Android 10 - 11
adb push default.prop /system/

# Android >= 12
adb push default.prop /

2. Terminal: Adjust permissions of the pushed file

adb shell

# Android <= 9
cd /system
chmod 644 build.prop

# Android 10 - 11
cd /system
chmod 644 default.prop

# Android >= 12
cd /
chmod 644 default.prop

Thanks for sharing this. As a datapoint for others, the following worked for me on LineageOS 21 (a.k.a Android 14) on beckham, after enabling USB debugging and rooted debugging:

adb root

adb pull /system/build.prop

(make edits as described)

adb shell mount -o remount,rw /system

adb push build.prop /system

adb shell chmod 644 /system/build.prop

(reboot the device)
