Screen capture permissions don’t update after calling setScreenCapture()

Environment

• Knox SDK
• Devices running One UI 6.0

Overview

The setScreenCapture() method can be called to allow or restrict a user from taking screenshots on a device. If setScreenCapture() is disabled initially and later enabled, device users might encounter unexpected behaviour. Either the screenshot is blank or the following error is displayed:

This app doesn’t allow screenshots.

Cause

The setScreenCapture() method stores the state of the screen capture permission as a flag. For most devices running One UI 6.0, this flag doesn’t update properly, causing the issue.

Resolution

To resolve the issue, you or the device user must restart the affected device.
