Difference between Com Samsung Android InCallUI and TelephonyUI

Distinguishing between the Android InCallUI and TelephonyUI apps can be tricky since both are system apps dealing with calls and user interfaces, and their package names are quite similar.

However, the name of the In Call UI app provides a clear hint about its function. This app is in charge of the in-call user interface that you see on your screen when engaged in a phone call. The call screen allows you to perform various actions like switching to speakerphone, muting the call, ending it, accessing the dialer app, and more.

On the other hand, TelephonyUI takes care of everything that happens after your phone starts ringing but before you actually answer or reject the call in the Android operating system.

Can you remove TelephonyUI app from Android phones?

The app comes already installed on your Samsung phone. Unlike certain system apps, you can’t access the app settings directly.

Since these hidden apps, including TelephonyUI, don’t have an option to be disabled, you can’t turn them off even if you try to navigate through the Settings app.
