iPhone or capable smart phone (Queens)

Hello again. Film school is in full swing and I had to borrow my brother's Samsung Smart phone for my film productions in the early going. Not sure what I am going to do as I'd hate to continue asking him to use his phone. A capable camera or smart phone would suffice if anyone can spare. I don't even care if the only thing on the phone that works is the camera, that"ll do. Thank you as always for your consideration.
