How to edit build.prop on Android

Android_10 build.prop_editing.md

Since various build.prop editor apps didnt work for me on Lineage 17.x, here the way I managed to edit build.prop:

1. via Termux/Terminal:

mount -o remount,rw /
nano /system/build.prop

2. edit to your hearts content - I usually bring down media vol steps: ro.config.media_vol_steps=15

3. mount -o remount,ro /

4. Reboot device

Editing build.props got more and more painful over the android versions - I'm no longer doing it myself.
But, from what I recall, on android 9, setting props with whatever build.prop editor app worked fine for me.

If it doesnt for you - a quick search implies magisk resetprop to be the go-to solution nowadays, maybe that'll help.
