so i bought the samsung galaxy note 5 and i notice when i open the camera and when its a little dark there is a black lines in the photos that i take how can i fix this please
Try clearing the cache for the camera app , But it looks like a sensor / lens problem actually try cleaning the lens , does it only happen in low light??
That looks like it's a defect with the camera. I doubt there's anything you can do to try and fix it yourself. Either take it in for an exchange or contact Samsung for warranty repair.
EDIT: Just saw this is two weeks old. Hopefully you have it taken care of.
