Question:

 Why are there pink dots appearing when using the Camera app on my Galaxy S20 FE?

Answer:

 The pink dots might appear due to damage on the camera's micro lenses caused by exposure to excessive heat, high-density energy, or direct sunlight concentrated on specific areas of the camera lens. To avoid this, try not to point the camera lens directly at strong light sources like sunlight. Damaged image sensors can't be fixed and will create dots or spots in photos.

Terms:

Micro lenses (part of the camera that focuses light onto the image sensor)

Excessive heat (too much heat)

High-density energy (a lot of energy in a small area)

Direct sunlight (sunlight without anything blocking it)

Strong light source (a bright light)

Image sensor (the part of the camera that turns light into electronic signals)

Irreparable (can't be fixed)
