Kousha Talebian, this will depend on your skill level. Take a look at [http://www.etradesupply.com/blog/how-to-repair-nexus-5-cracked-screen/|this video] and see if that is something you would work on. About the display being real, hard to say. I have dealt with etradesupply before and have not had any issues. But if you do not feel right about it, I suggest you check around. Hope this helps, good luck.
