iPhone 12 Pro Max
It cannot be repaired. The back glass on iPhone is fused. If it is smashed, the entire phone must be replaced. If you purchased AppleCare+ when you bought your phone, the cost to replace the phone will be $99. If you did not purchase AppleCare+, the cost to get an Out of Warranty replacement will cost you $599.
