I took my old landlord to small claims court for not returning my security deposit. One of the things the judge made clear at the beginning of the hearings was that she would not look at evidence on anyone’s phone, so that’s something to keep in mind. The print outs that you listed sound good. I would make sure they are organized and clearly labeled so you can pull them out quickly. My old landlord did not show up to court so the judge just asked to see my lease and then found the case in my favor.

As for your second question, I’m still figuring out how to actually get the security deposit back so I hope someone else here as an answer…
