Hey! How are you?
Everybody who uses Android device should know that Android is an Open Source Project by google. Android is developed by google and it is open to developers unlike the Apple IOS or Windows.
The manufacturers are using it as their source for the Android devices. And they can customize it as they want because it is open and even you can develop Android(but you will have to know programming?). So Android is free to all.
So you guys should know that AOSP stands for Android Open Source Project.
