In the world of smartphones, particularly those running on Android, there are countless system packages working behind the scenes to make our daily interactions seamless and intuitive. Among these, two significant packages play a crucial role in how we make and receive calls: com.android.incallui and com.samsung.android.incallui. These might sound complex, but they’re quite straightforward once broken down.

What Are They?

Simply put, com.android.incallui and com.samsung.android.incallui are system packages responsible for the user interface (UI) you see and interact with during phone calls.
