There are three phone apps on your Android device because each app serves a different purpose and provides different functionalities.
1. Dialer App: The dialer app is the main interface through which you make phone calls. It provides you with a numeric keypad to enter phone numbers manually or select contacts from your address book. The dialer app also gives you access to call logs, allowing you to view your recent calls and easily redial numbers.
2. In-Call UI: The in-call UI (User Interface) app is responsible for managing and displaying the interface during an active phone call. It provides you with options such as putting the call on hold, switching to speakerphone, muting the call, or accessing additional features like call recording or call waiting. The in-call UI app also displays the call duration, allows you to add participants to a call, and provides access to other call-related settings.
3. Phone Storage: The phone storage app is not directly related to making or receiving phone calls, but it is a necessary component of the phone app system. This app manages the storage space on your device for various phone-related data, such as voicemail messages, call recordings, and other phone-related files. It ensures that these files are stored securely and can be accessed when needed.
Additionally, some Android devices may have a carrier-specific phone app. This app is usually pre-installed by your mobile network provider and contains settings and features specific to your carrier. It may include options like managing your voicemail, accessing carrier services, or configuring network-related settings.
Having separate apps for different phone functionalities allows for better organization and easier access to specific features. It also enables developers to update and improve each component independently, enhancing overall functionality and user experience.
The presence of three phone apps on your Android device is normal and serves different purposes. The dialer app is for making calls, the in-call UI app helps manage active calls, and the phone storage app handles phone-related data. Additionally, a carrier-specific phone app may be present, offering carrier-specific settings and features.
