Black screen after dropping

@hassan29369 all of that sounds like a bad display. Time to replace the display. Since iFixit does not yet have a guide for that, use the one from here. It is written in Spanish so use a browser that can do the translating for you, if needed. Replacement screens are readily available at many 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 a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
