I can see it fine as I'm taking the image but if I view it in the gallery it is all white. Do I need to clean it; if so how? Honestly, I have no clue how to even try to fix this. I tried to reset the settings and reattach the lens but nothing helped .
First you need to check your camera settings. This could be something as simple as slipping the camera into manual mode and over exposing.
Can you replicate the bright white with the lens fully covered by a lens cap?
If yes then you have something electronically wrong with your camera and you need to call Samsung for service.
Is the camera in automatic mode or manual mode?
If the camera is in manual mode then try changing it to automatic mode.
Can you use the video mode without the camera washing out?
If these are fine then it could be a physical shutter issue, in which case I'd recommend calling Samsung's support number.
