When I opened the Camera app on my Galaxy S8+, I noticed there was a small black spot on the image. It only appears on the front facing camera. I've attached a zoomed in image of what I'm seeing.
If you move the camera around, does it show in the same spot all the time with the same hue/color? Have you checked your lens? Looks like either a cracked lens or some debris in between the sensor and the lens. Might be a sensor issue (damaged pixels) but looks too 'soft' to me to be that.
