Phone receives calls and vibrates but screen is black. No Samsung logo

@tamsin84991 this "My phone fell. It vibrates" is a pretty good indicator that you are dealing with a broken display. I t may not be cracked but most certainly received some internal damage. In order to fix your phone, you will have to replace it. Since iFixit does not yet have a guide for that, use something like this video or even this one Screens are readily available on plenty of online stores.

While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
