So earlier today I was taking pictures of math notes with my iPhone 7 Plus, and as I was looking at the pictures, I noticed something... There was a little multicolor splotch on the picture. I thought it was on my screen but when I tried to scratch it off, it moved with the photo. I zoomed in and it zoomed with it. I checked all other pictures I recently took and the splotch was only on the photos taken in the last 24 hours. I checked and cleaned my camera lens and there doesn't seem to be any scratches or smudges capable of producing such a spot. When using my camera, it zooms in when I zoom, and remains in focus whenever the picture is out of focus. This tells me that there might be something wrong with the camera itself... It doesn't effect my use of the iPhone camera, but it sure is annoying!
