I recently exchanged for the "safe" Note 7 at AT&T and after a week a black spot appeared on the screen under the glass. I thought it was a dead pixel at first but when I hold it under a light, I can see it is actually something under the glass. I thought this was impossible because the glass and the digitizer were attached. I went to the store and they said that every store in the area was out. They were really unclear when they would get any or if I would even be able to exchange for another one. One employee told me that any they were getting were for replacing old ones and that if I couldn't do anything within 14 days, I should go through the warranty exchange. I looked at the exchange policy and said that I would be getting a CERTIFIED LIKE NEW device if I did a warranty exchange. I do not want a certified like new device. I want a NEW device to replace the obviously defective one. I've been at the AT&T store for over 6 hours in the past two weeks because of all this. What do I even do now?
