@jcb77 it is always easier to change the display with the mid frame. I would suggest you use the guides [https://www.nadiemellamagallina.com/en/manuales/smartphones-1/honor-715/honor-view-10-716/|from here] It will show you how to replace the screen with the midframe. They are written in Spanish so use a browser that does the translating for you (if needed)
About your rear camera, that is a different frame and you may need to replace the back of your phone. Hard to say since we can't see the damage :-)
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. Repair is War on Entropy!
