I currently have an iPhone 5c, ME553LL/A, and while using a lifeproof case (yep), the top of the screen cracked, from top to side, branching twice. The top of the screen is black, and I usually can't see it with the lifeproof case on, but I am wondering whether or not I should get it fixed. It doesn't cost too much for my area, about $60, but will this be necessary for my phone to work? If I dont get it fixed and too much pressure is put on it, will it break completely? When I rubbed my fingers over it, I only felt 1 small crack, while the others were so small I could not feel them.
