Device Remote Lock

Device Remote Lock remotely locks devices and displays a customizable message prior to repair, replacement, decommissioning, or other purposes.

Overview

The Device Remote Lock feature allows organizations to remotely lock devices and display a predefined message on a customizable screen. This helps manage devices designated for repair, replacement, decommissioning, or other purposes, while also preventing unauthorized use during these processes.

This feature is only available on devices with Launcher 3.25.29 or higher.

User Guide

When Device Remote Lock is activated, deactivated, or even during Launcher startup, the device adjusts its behavior to prioritize security until certain requirements are met. Understanding how the feature operates in these scenarios equips users to manage it effectively.

When Lock Screen is Activated:

  • If a user is logged in, the system will automatically log the current user out.

  • The UI will change to display the new Lock Screen interface.

  • Device controls, such as the notification pull-down, will be disabled.

When Lock Screen is Deactivated:

The UI will update to confirm the device is in Open Zone.

During Device Boot / Launcher Startup:

If the device was locked before rebooting, the device will automatically return to lockdown mode after completing the startup process.
