I am going to AT&T to replace my Note 5 because of a camera issue(buzzing/crackling sound). Understand that they will send me a phone which is a certified phone that was in some kind of damaged box but was checked. If I had gone to Samsung I would have to send in my phone wait and for it to be repaired and could get it back. Can anyone tell me if you had a bad experience by going AT&T or samsung warranty replacement? Which would you suggest I go to?
