Hi, I have an iphone 6 with the crescent moon front camera issue and also, the screen clicks when i press it. I've read that apple would replace the phone if i take it to an apple store (it's on warranty until october). Should i have the phone replaced? Or just ask for a screen replacement? The phone works perfectly, i don't know if i want to take my chances with a refurb unit... Does the refurbished unit have a one year warranty? Thanks!
