The iPhone Duo is a strong first foldable from the company, but multiple Reddit reports say the phone's inner screen cracks when customers open the device. Some apparently happen very soon, like during device setup. (Others might be from influencers trying to break the thing, like YouTuber JerryRigEverything.) People are already calling this “crackgate.” It's unclear how widespread the problem is or whether it only affects a small number of units.
