You can boost internet speed, change phone specifications, increase system performance, make almost all apps compatible or trick websites to display a tablet interface. So here’s how to edit Build.prop file. This are only a few things you can do if you edit your build.prop. In this tutorial I am going to teach you how to edit LCD density by editing build.prop. You can follow this tutorial for tweaking almost everything inside the build.prop file. Before we start, note that we need a rooted android device to edit this file.
