Never had a cellphone but I have an iPad tablet that has basically the same operating system as a phone. I dont set the screen to lock. Is that what you mean? Where you have to input a code to unlock it? I dont set that. Its never locked. Its either off or on my Home Screen. As for the photo background its the same as my Home Screen default.
As for my Home Screen it was apples default wallpaper from like 7 years ago I liked. Its a snow capped mountain with a night time starry sky. I liked it so when I got my new iPad in August I kept it.
