How to enable preloaded applications (calculator, phone, etc) in the launcher?

Question

I need to display the icons of the applications already existing in the system: phone, calculator, file manager. How can I do that?

Answer 1

To enable a preinstalled application, you must know its package ID.

The list of applications installed in the system can be shown by the "AppList" app, which can be downloaded here.

Note: package ID in the picture is com.samsung.android.dialer.

After you get the package ID, open the Applications tab and click "Add".

Enter the package ID and name, set Version to 0. Select the "System" flag to indicate that this app is already installed in the operating system and doesn't require to be uploaded.

Click "Save", then choose in which configurations should this app be allowed. 

This will do the task.

Answer 2

Package IDs of well known apps could be found in the address bar of Google Play or apkpure.net.

Answer 3

Another way to determine the package ID. Run the application (dialer), and at the same time connect to the device by adb, and run the command:

ps -A

This will show you the list of running processes, and you may guess which one is related to the dialer.

If you can't get it, then kill the dialer (click recents then swipe up), and re-run the command 'ps -A'. You should see that one of the packages is absent - that package must be related to the dialer.

Once you get the package ID, add it in "Applications" as a "Preinstalled application" and add it to the configuration.
