What is build.prop on Android? How to edit it

The build.prop file in Android is a system file that contains various system properties, such as device model, Manufacture, Software Version, and other system settings. It is located in the /system/ directory on an Android device and is used by the operating system to determine how it should behave on a device.

The build.prop file can be edited by users with root access to their device, allowing them to modify certain system properties and settings. However, it is important to be careful when editing this file, as making the wrong changes can cause system instability or even render the device unusable.

  • ro.product.model: This property identifies the device model.
