When navigating within a virtual device, you can at any time change its display:
- Full-screen mode: You can switch to full-screen mode by pressing F11. Pressing a second time reverts to the original screen size.
On macOS, you may have to use the key combination ctrl + fn + F11.
- Custom size: You can resize the virtual device window by selecting and dragging an edge or a corner of the window.
- Fit to content: When the virtual device window is resized, black areas appear on the borders. Double-click in one of those areas to fit the virtual device window size to its content.
