I am incredibly frustrated with this issue, and not entirely happy with how Apple has handled it up to this point.
My original iPhone 6+ I had for about 6 months and the clicking started, a couple months before my warranty expired I took it in for service and at this time the represenative told me I would have to leave my phone with them for 1.5 to 2 hours for them to replace the screen, I wasn't happy with this answer and that was all they could do to help me at the time. I wanted my device replaced, no need for me to stand around a mall I have no intrest at being in for the better part of 2 hours.
I called Apple support and long story short they sent me back to the store with only a 45 minute screen replacement.
A month later the dreaded clicking came back, this time out of my warrant. I did have the 90-days parts and replacement warranty. I called my guy at Apple and he got me another appointment, for them to again, replace my screen.
Went to this appoitment, had my screen replaced. Not even a week later and it is happening again, called my guy at Apple - he promised a product replacement this time and would note it in my file since I have an out of warranty device.
Got to Apple Store last night for appointment. No notes where in my file to reflect a Customer Satisfaction device replacement - so I had to re-explain all my problems, show them that I've been working on this same issue since before warranty expired and then they decided they would replace the device.
This is part my fault too, I guess, I should have inspected the device before leaving the store. I just didnt expect to recieve a 'loose screen' iPhone 6+ from Apple's refurbished devices, but low and behold I did. This ones screen clicking at the top of the device is so much worse than my original iPhone 6+.
I e-mailed my guy at Apple last night, I'm so incredibly frustrated at this point. Going to the Apple Store is a huge inconvience for me, the closest one to my home is 45 minutes, I hate the mall and the amount of time I've had to put into fixing this problem is flat out ridiclious. Hopefully I will hear something from Apple today, and just sending me to a store, again, is REALLY going to make me mad. I've dealt with this issue as an adult the entire time now, but now im getting fed up with being nice about it. You shouldn't expirence this same problem over and over on a device that cost almost $1000!
