iOS and Android devices have app switchers that display screenshots of your apps. This is a possible privacy risk for apps that display sensitive information. To enhance the security of on-device data, SAP Fiori Client includes the Privacy Screen plugin, which hides application content in the app switcher.
The Privacy Screen plugin is an open-source plugin (see PrivacyScreenPlugin) that is included in SAP Fiori Client for iOS and Android. If you build a custom SAP Fiori client, this plugin is added to the project automatically.
If necessary, you can disable the privacy screen for a custom SAP Fiori client.
