3 Blue Circles

This puzzle screen shows 3 circles on the screen as below.

Solution: This puzzles uses the microphone on your device to hear ambient noise. When it picks up noise there will be lines moving on the screen

The three different lights are activated by different levels of noise:

Top light: No noise heard (no lines moving). Maintain quiet for 5-10 seconds to activate this light.

Middle light: Normal noise (some lines moving). Maintain a normal backgound noise level such as normal talking near the phone or music.

Bottom Light. Loud noise (lots of lines moving). Shout near the phone, play loud music or I also found blowing on the mic worked.
