Hi, Recently, my iPhone 5c home button started to be temperamental and doesn't work every time I press it. It has gotten very annoying and sometimes I have to press it up to 10 times before it works (I am just pressing like normal). I can't even open multitasking because the chances of the button responding twice in a row is nearly zero. I do have a Griffin Survivor case on it but I have taken it off for a period of 2 days and the button was still defective most of the time. Now, I have assistive touch turned on but I would prefer not to have to keep that turned on for the next 2 years I have the phone. I'm thinking about going to an Apple store for the first time ever(It's more than an hours drive and in the most inconvenient spot on the edge of the city even though I live in a big city). I was going to go to the Genius Bar and see if they could repair or replace my phone (yes it is still in warranty). My questions: 1) Do I HAVE to make an appointment with the Genius Bar? Like I said it is so inconvenient to go to my apple store and I would rather just walk-in than be late. ALSO, if I HAVE to make an appointment, how far in advance? 2) Are they able to fix home buttons in store, or are they more likely going to replace it. 3) if they replace my iPhone, is it likely to be a new or used device? 4) is there anything that would stop them from fixing or replacing my device? (I have no jailbreak, no dents, no cracks- looks in great condition!) 5)after they repair or replace the device is there anything I should look over before leaving since I don't want to drive back and find out something is wrong? 6) anything else I should expect? Thanks for answers!!! EDIT: Here is my follow up to my great experience for my first time ever to the Apple Store!
