Hello! I have a problem. When i take a polaroid picture it comes out with a white corner on its up right. Sometimes it comes out bigger, sometimes smaller. Is that a problem with the camera ? Please help :)

I bought a second hand Instax and had the exact same problem. Open the top cover (where the film comes out), do you see straight to the rollers (silver)? In my case, the second hand Instax was missing a piece of ‘black sponge’ that helps with spreading the developer (chemical) on the film. I found out when I compared it to my previous (broken) Instax. I took the ‘black sponge’ from my previous Instax and put it into the current one and the problem is fixed!
