The Measure app will look for the red laser dot on the image shown on the screen. When the dot is located, a small green box will appear around the dot to indicate it has been found. If the image has other bright areas or the surface you are shining the laser on is reflective, the app may struggle to locate the laser dot. In situations like this it may be neccessary to manually tap the laser dot location on the screen.
For best results:
– Adjust the Exposure value to make the image darker or lighter to help the dot show up.
– Shine the dot onto a non-reflective surface.
– Keep any other sources of bright light out of the images.
