How to backup my Iphone when the screen is not working?

The LCD of my Iphone is not working because I dropped it in water, IIm not willing to bring it to the shop since I've already spent $250+ on fixing it before, so now I want to get all the data in it backed up but I can't unlock it, is there another way?

Get some rice. Burry the iphone in the rice in a bowl for 1-2 days. Then try using the phone.
