I posted a few days ago about the probability of getting an i4S replaced despite the sensor being activated. So, I finally got a chance to go to the Apple store, feeling ashamed of having to ask for a replacement, pondering whether I would end up having to argue for the warranty. I come to the councils I would just take the phone as is (I paid full price on this thing) if I didn't get a good deal. After waiting for my appointment, I tell the guy the problem, he automatically checks the warranty, and says "I'll be right back. I'll get you a replacement." I'm so stunned I forget I can't even utter the words "Thank you", and instead I just nod. That's it! Didn't even check the sensor! The rest of the phone was working perfectly fine (problem was the sleep button), so I guess he just assumed it was manufacturing defect, or 2) that it was pointless to check all sensors when there was only one little problem. Good thing, 'cause I'm not very good at arguing for a phone lol. The girl before me even had to scream haha, BUT her phone was smashed. I love Apple. I was already hating on all my Apple products thinking of the possibility my warranty would be "void" LOL! Well, thought I'd share the story of yet another Apple satisfied customer.
