Hey guys, recently my iPhone 5's lock button has started playing up and become unresponsive to the stage where most of the time it just flat out doesn't work. I had this issue with my first iPhone and Apple happily replaced it with no questions asked. Problem is, about 3 months ago I dropped this phone which caused a dent on the top-right hand corner, near the lock button. The two problems aren't linked - the lock button was fine for 3 months, but Apple doesn't know this and it's my word against theirs. What are the chances of getting a replacement? The rest of the phone is in mint condition... Thanks!
