The Measure app will search for the red laser dot on the screen image. When the app locates the laser dot, a small green box will appear around it.
The Measure app may struggle to locate the laser dot if there are bright areas in the image, or if the surface you are shining the laser on is reflective. When this happens, it may be necessary to manually tap the laser dot location on the screen.
For best results locating the red laser dot
- Adjust the Exposure value to make the image lighter or darker. This will help the dot to show up.
- Shine the dot onto a non-reflective surface.
- Keep any other sources of bright light out of the images.
