Difficulty: MediumTroubleshooting Mobile OS Security and Connectivity Issues

An employee reports that after downloading a third-party battery optimization utility from an unverified website onto their corporate Android device, the phone frequently displays persistent overlay advertisements and battery drain. When the technician attempts to uninstall the application via the standard Application Manager, the Uninstall button is grayed out. Which of the following is the BEST initial action to revoke the application's elevated permissions and allow standard uninstallation?

  1. Revoke the application's active Device Administrator privileges in the security settings.Answer
  2. B
    Perform an immediate factory reset of the mobile OS to clear system memory.
  3. C
    Contact the cellular service provider to issue a new SIM card and clear network access profiles.
  4. D
    Reconfigure the corporate wireless access points to use WPA3-Enterprise encryption.

Answer

Revoke the application's active Device Administrator privileges in the security settings.
When a sideloaded application receives Device Administrator rights, the operating system grays out the option to uninstall it to protect system-level processes. Deactivating these administrative rights under the device security settings revokes the protection lock and restores standard application uninstallation capability.

Step-by-Step Solution

1
Identify the cause of the disabled uninstall option
Recognize that the grayed-out uninstall button indicates the application holds active Device Administrator privileges.
Mobile operating systems lock application removal when an application is registered as a active Device Administrator.
2
Navigate to the Security settings on the mobile device
Access the Device Admin Apps / Device Administrators menu.
This security menu lists all applications granted system-level administration rights.
3
Deactivate Device Administrator privileges for the problematic application
The application loses elevated rights, enabling normal management actions.
Revoking these rights removes the OS removal restriction.
4
Uninstall the application through the Application Manager
The application is successfully removed from the device.
With administrative privileges removed, standard uninstallation functions normally.
