The “build.prop” file is a system file that exists on every Android device. The file contains build information and other system properties which are used throughout the operating system.
System properties are string key-value pairs. You can create or modify a system property in the build.prop file which will be loaded when your device first boots.
The file is located at /system/build.prop. The build.prop file allows single line comments that start with a ‘#’ character.
Some common system properties include:
ro.sf.lcd_density: controls the device density.
ro.telephony.call_ring.delay: the number of milliseconds between ring notifications.
persist.adb.notify: flag to show/hide the ADB debugging notification.
lockscreen.rot_override: flag to enable/disable rotating the device when the screen is locked

Device manufacturers add their own system properties and may change the behavior of system properties on your device. To get a list of all system properties on your device you can run adb shell getprop from the command-line.
Backups are saved in the application’s private data folders. You can change the backup location in settings.
To create a new backup open the navigation drawer and select “Create backup” from the menu.
System properties are small name value pairs managed by Android’s property service. All system properties are loaded at boot. You can get the value of any system property without root access. You need to have root access to modify or create a system property.
The property name can be a maximum of 31 characters long. The maximum property value is 91 characters.
The property’s value can be a string, a number or a boolean (true or false). Values 'n', 'no', '0', 'false' or 'off' are considered false. Values 'y', 'yes', '1', 'true' or 'on' are considered true.
Your device needs to have root access to modify the build.prop or add a system property. However, you can still use BuildProp Editor to view device information and create a backup of your build.prop without root access.
