Was coming here to say this, when I moved into my apartment, I took pictures of every square inch of the place. Then, I emailed the pictures to the apartment complex. That way, you have a time dated proof if anything was damaged upon moving in so they don't try and blame you for any pre-existing damage. Even take pictures of the AC closet. They tried to get me for water damage that happened because of a leaking AC unit. I then directed them to the email I sent when I moved in, where I had picture's and even raised concerns about it. I was able to get my full deposit back because of that email.
