In corporate-owned android devices with secure launcher profile, you may come across an issue that the Status Bar at the top of the screen which includes a clock, battery status, and network status are missing. However, when you enter the admin passcode for the secure launcher you would be able to see the status bar.

Launcher 4.0 uses new native Android APIs for Google EMM Registered enrollments in the standard Android profile. These new APIs fall under the umbrella of Corporate-Owned Single-Use (COSU) mode. Some features are removed while using COSU mode, this is purposeful to be able to drastically increase the security of the Launcher application.

To resolve this issue, just disable the COSU (Corporate-Owned Single-Use) adding a custom XML profile on the secure launcher payload.

Tested device: Samsung note S series.
WSO UEM Console: 9.X 
Secure Launcher ver: 4.X 

In DO mode, COSU will be configured by default.

Just add that XML as a custom setting to your launcher profile.
