Hey, Do you know if Apple still replaces jet black iPhone 7 under warranty with the same jet black model or do they give you another colour considering the jet black is no longer in production for a long time now? My college sent his phone back to Apple due to microphone not working and they acknowledged the replacement request. He's just worried about the jet black colour. Also have you heard of any incident when Apple replaced an iPhone under warranty with a newer model? Like 7 to 8.
