What is Build.Prop

Generally, Build.prop file will be stored in /system/ path in Android Operating System Devices. In Which, All Phone Specifications, Tweaks, Settings Will Storing. This file is very important for all android phones. Without this File, Android Phone can survive but, if you restart your phone, then it will not boot up. So, usage of Build.prop is very important for Android Phones.

You can Easily this file, If you have rooted your Smartphone. If you don’t have rooted Smartphone, then you will not be able to edit this file, because this file is available for edit for use for Rooted Smartphones only. Because, Without Root you can’t change permissions in your Phone. You can Add Below tweaks, in your Phone’s Build.prop file after you root your phone. then you can optimize your phone easily. So let’s checkout Some Easy Steps, for How to Use Build.prop in Smartphones.
