My guess is its a year more people decided to finally upgrade? I know my phone is now 4 years old and I wanted to get one, but due to financial reasons I am trying to stick it out another year. I just hope I make it since earlier this year or late last year my sceeen went dead and I thought I was screwed... I decided to drop it and shockingly it worked! Fingerprint sensor went dead as well at the same time but once i rebooted it came back as well so it must be a loose cable connection. Its been fine ever since, but I do feel like im on borrowed time.
