Made an appointment at the genius bar a couple of days ago and went to exchange my phone due to 1) dust forming under the screen and 2) slight rattling noise when shaking my phone (possibly due to something loose inside). The rep confirms the rattle noise but says to me "It's normal, it's from the accelerometer". I'm thinking in my mind, how the hell is this normal? He then says to me "This is your 3rd exchanged phone. What's the issue?" I then tell him to look at the previous notes on my exchanges phones. I tell him all of the previous reps confirmed my issues on the previous 2 phones. Phone 1 had improper body construction as well as dust forming underneath the screen. Phone 2 had dust forming underneath the screen after a couple of days. The rep looks at my account and says "Hold on, I need to speak to a manager". After a couple of minutes he comes back and says "Ok, we'll do another exchange for you but, this is a courtesy exchange." He then goes and tells me that they can't keep on exchanging the phone for a couple of dust pieces forming underneath the screen. He tells me when the dust gets bad then that's when I can come in for a "true" problem. I'm like um WTF? How is it not an issue when dust is forming underneath the screen after a few days? Whether it's 100 dust pieces of 3 pieces. He hands me an exchange and the new phone has 2 HUGE pieces of dust under the screen. I point this out to him and he tries wiping it off (of course you can't genius, it's under the screen). Needless to say at this point I'm pissed off and tell him Eff it, I'll just keep my old phone and walk out. I remember someone mentioned that the stores are trying to limit the number of phones being exchanged for a customer. Is that true or did I just meet a ****** genius bar rep?
