Unable to view lock screen when using Knox Remote Support on desktop

Environment

• Knox SDK
• Knox Remote Support

Overview

When using Knox Remote Support to control a device, users may encounter an issue where the lock screen of the device is displayed as a black screen on the Knox Remote Support interface.

Use of FLAG_SECURE in the lock screen

Apps that use FLAG_SECURE can prevent their content from being shown on certain displays. As of Android 13, the lock screen sets this flag when displaying a PIN, password, or pattern prompt, causing the Knox Remote Support interface to display a black screen instead.
