Did you know that there is a whole dedicated system to manage the calling function on your Android device smoothly? com.android.server.telecom (used.com.android.server.telecom service) is the Android Telecom framework that governs the calling functionality on Android devices. Curious to know more about the framework, its importance, and how it works? Read the blog to the interesting answers.
com.android.server.telecom is the Android service package that works as the interface required to make audio and video calls and other functions related to calling. It initiates, ends, and manages calls, including SIM-based calls using the Telephony framework, Voice over calls using SIP, or a third-party VOIP ConnectionService.
The com.android.server.telecom uses the Android framework to establish the connection after a call is initiated on an Android phone. It also displays the options we see on a dialer during a call.
The Android Telecom framework supports two essential components: ConnectionService and InCallService.
ConnectionService is mainly used for telephony ConnectionService to connect calls with mobile carrier networks.
InCallService works with com.android.incallui APK file to provide a User Interface to manage calls. For instance, the Dialer app provides different functions like Dial, Disconnect, Hold Call, etc. The most basic functions include Outgoing calls, Incoming calls, Hold calls, Resume calls, and Disconnect calls.
The Android Telecom framework includes three important components:
com.android.server.telecom acts as the bridge or middle tier between the dialer app and the phone modem. It receives the information from the dialer app and initiates processes. For instance, we make a call through the dialer app, com.android.server.telecom receives the information for the Telecom framework and initiates the setDialing system process. The setDialing process informs the Telecom framework to connect to the phone modem to dial the call.
Similarly, the com.android.server when we disconnect the call.telecom initiates the setDisconnected system process to instruct the Telecom framework to connect with the phone modem to disconnect the call.
The function is responsible for incoming and outgoing calls. It displays the name and other details on the screen during calls.
As the name itself explains, Call.details fetches the caller’s details from the android system database to display.
The Call.Recall function is responsible for creating the route for the Call or rerouting the path for the Call to facilitate users a smooth conversation.
Callaudiostate stores all the data related to a call. For instance, caller id, IP address, how long the Call was muted or on hold or the total time of call, and other details. In addition, it also stores call recording information from start to end.
Call.Recall function holds information for call redirections or diverts. Look for CallRedirectionService for information if the call is diverted to another number.
CallScreeningService function works Call and call.details functions to display the caller details for incoming Calls. It also shows the details of the blocked contacts.
The conference function holds all the details about the conference calls. For instance, the number of people connected, the call duration, and the calls disconnected. In addition, geographic locations of the people who connected.
Conferenceable works with the above function to store all the data related to the conference calls.
Connection.VideoProvider function stores the details of the video calls. It doesn’t support the social media video calls like Whatsapp, Facebook, Instagram, Snapchat, or others.
If a call was disconnected, this function explains all the technical details and reasons for the disconnect. For instance, the person disconnected the Call or was disconnected due to a bad network connection. Other reasons may be out of coverage area, or the number is switched off or in a flight mode. DisconnectCause explains every detail about the cause.
We can say that it is the supervision section of all other functions. All the functions related to the Calling work under InCallService.
PhoneAccount stores all the contact details.
StatusHints displays received calls, outgoing calls, and missed calls which we see in our call history. One can quickly check the number of outgoing and incoming calls of a particular number.
Video Profile stores the details of the video calls, like the number of people and duration.
VideoProfile.CameraCapabilities function checks the quality of the camera and the path of the people who will join the video calls.
There are some popular Android dialer apps that you can use to manage the whole Calling function.
Truecaller is the oldest and the most popular and dialer app. It has the best tracking features, a user-friendly interface, and a flash messaging option. Truecaller quickly detects the number if the number is not in the contact list. The app is quite popular in Asian countries like India and offers free and paid versions.
The Eyecon app is a picture-based dialer book to let users simply see & call. With a 4.5-star rating on Google Play Store, the Eyecon app has an intuitive dialer, displays names and photos of calls, blocks spam calls, and many other exciting features and functionalities.
The users can see the name & photo before they even pick up the call. They can click on the icon to get more information about the person on the other side. The app also offers access to a caller’s Social Network while in-call.
The dialer is another popular app that detects callers. The users can also download the information on their phones for future reference. The app offers a simple interface and many theme options which users can change whenever they like.
No, one cannot uninstall com.android.server.telecom. It is a built-in service and does not support uninstallation.
No. It just means the phone made an active connection with the carrier service and its network. The phone routinely checks the network for better signal. For instance, it checks for any stronger signal nearby to switch.
No, but you can erase the call history by using some software.
As the name suggests, Android IncallUI (com.android.incallui) provides the user interface for the phone’s Call dialer app. The elements shown in the call screen, like the Call button, Disconnect button, Hold button, Speaker button, etc., are stored in the com.android.incallui app.
On the other hand, Android Server Telecom manages audio, and video calls for mobile SIM carrier networks using telephony service framework and VOIP with the ConnectionService API by connecting to the phone modem.
com.android.server.com is an integral part of the android server telecom framework also very essential for every android device. There are alternatives available like Truecaller, Eyecon, etc., but it is recommended not to uninstall com.android.server.com from the phone. Uninstalling will create hard-to-solve chaos on devices.
