Apple iPhone green camera dot and Samsung proximity light clarified

Apple’s iPhone displays a small green dot in the upper‑right corner of the screen whenever an app accesses the camera, a privacy feature introduced with iOS 14. An orange dot indicates microphone use. Users can manage camera permissions via Settings → Privacy → Camera.

Samsung Galaxy devices may show a tiny white blinking point near the front camera during calls. The light is the illumination of the proximity sensor, which turns the display off when the phone is close to the ear. The behavior is normal; persistent or abnormal flashing may signal a hardware issue and can be addressed by cleaning the screen, removing protective accessories, restarting the phone, or seeking service.

Both indicators aim to increase user awareness of sensor activity, though Apple’s implementation focuses on privacy alerts, while Samsung’s reflects sensor operation.
