This Knowledgebase article contains details about a specific behavior in Device automation.
When the robot loads the Device Automation screen in the step workflow, the screen is black and finders don't work.
This can happen if:
- the device screen was locked (using Start > Lock screen) and not the "Lock Screen" feature from the Device Automation menu options (the system tray icon menu). This action will not allow the robot to see the screen
- there is an active Remote Desktop session (to the device) and the RDP window has been minimized in the task. This action puts windows in a gui-less mode and the robot won't be able to see the screen
- If the device was locked from Start > Lock screen, use an Open step to open a headless RDP connection to the device. See section "Use RDP Connection" in the User's Guide for more information.
- If an active RDP session is minimized, the easiest is to just avoid this. E.g. If you have multiple windows, move the RDP window to a different screen and leave it maximized. Or, if this is not possible, simply switch between the RDP and Design Studio windows, instead of minimizing the RDP window to task bar.
