How do I lock the focus on ScoreCam and turn off auto focus to prevent focus hunting?
To turn off/disable auto focus, tap and hold on the center of the screen, and at the top of the page it should say in yellow "AE/AF Locked." This means that auto focus is turned off and you are setting the focus and exposure of the camera on a specific point. The camera icon at the top left of the page (right next to the bluetooth icon) should be yellow when "AE/AF Locked" is enabled. To disable "AE/AF Locked," simply tap and hold the anywhere on the screen again, and at the top of the page it should say in yellow "Auto Enabled."
