Users can access this feature through the preferences menu option or by simply long-touching the display while a test is running.

Gestures:

• Slide left-right: Change the test image
• Slide up-down: Adjust brightness
• Long touch: Switch between full screen and normal screen (Android 3.0 and higher)
• Double tap: Hide or show the test-specific settings dialogue (if available)

Please consider purchasing the Pro version to support further development.
