Yeah… They sent back my phone for a screen replacement because of a chip or scratch on the back of the phone and quoted me like $400 to fix the whole thing..

Another time, they said my front facing camera wasn’t working when I took my phone in for a battery recall, I managed to be on vacation and have plenty of pictures taken with my front facing camera that day before I took it in. They actually replaced it that time for free with no Apple Care. They said they probably forgot to reconnect it and didn’t want to reopen it, so they just handed me a new phone.
