Android Phone - build.prop tweaks (Root Only)
Following is an extensive list of build.prop tweaks you might want to fiddle with, if your android phone is rooted. For editing build.prop file, you need to download es file explorer from play store, then mount the system as R/W since the file is /system/build.prop. Before starting, take a backup of your build.prop file.
1. Locks default launcher app in memory. Only use with light launchers:
ro.HOME_APP_ADJ=1
2. Improves audio and video recording quality:
