Just the Glass, Digitizer, or LCD?
So yesterday, I dropped my iPhone 5. Less than 2.5 feet from the ground, and it cracked the tiniest bit, just along the top right WITH a giant rubber protective case, AND a front protective glass cover on it. It now has one small crack, and the stupid thing will not work. It turns all the way on, and I can see it light up, but the screen remains black, and it gets one white line down the middle of it. I can tell it still works because it still remains at 100% battery when I plug it into my MacBook, and it also still plays my music when I plug it into my car, I can access my entire iTunes library and address book.
So, my question is, is there any way to tell before I go into the whole process if I need to replace the digitizer and/or LCD screen or if it might just need the front glass replaced or should I not even bother and just get the entire new front screen unit? I took off the entire front unit, digitizer and all yesterday to see if maybe something had just come loose and needed to be adjusted or something, but the screen still just stays black. Even after all of that, though, I could still plug into my car and listen to my full iTunes library (if that helps). Probably still would have to replace the LCD, though, I'm guessing?
