So I found this iPhone on eBay but the seller keeps saying "it has a cracked digitizer but is fully functional." How can this be possible?! I thought a cracked digitizer meant the phone didn't respond to touch in certain areas (these are areas that have a big white spot) how can the phone be functional?? I keep asking him where the white spots are but he's not messaging me a photo. What IS the impact of a cracked digitizer? How does one define "fully functional" Am I being scammed? Thanks!
