When I record with flash on my phone the screen on my phone shows it flashing red and green and it sometimes loses focus. This does not happen when recording any other parts of the led light

Focusing on reflective surfaces is challenging, so it’s not unusual to see refocusing like this.
To me, the red and green during focusing look like it may be caused by longitudinal chromatic aberration. This is a color phenomenon common in lenses in front of, and behind the plane of focus. It is probably being removed by the camera software, but not instantly/consistently.
