My Selfie Camera is showing a weird triangular shaped artifact in the middle-upper portion of the frame. This doesn't seem to affect the performance of the camera in daylight, but at night under some circumstances I can spot it and it's a bit disappointing. I don't know if that's a reflection caused by the front lens elements or perhaps a defective camera sensor. I managed to take a shot in my room right after I turned the lights off and it's shown pretty clearly. I marked the bounderis of the artifact and slightly boosted the overall brightness of the shot so it's clearer to see. I wonder if you could test your selfie cameras in a dark room and see if you can spot this as well.
