I got my iphone 6 about a week or so ago, and I set it up new. I've never had an iphone, I always had android. Anyways, it randomly clicks on things sometimes. I mostly notice it when using the browser and the facebook app. It will 'like' a photo by itself and things. I just got this phone and don't want to return it. I did a factory reset and it still does it. It's not consistent though. Like I can't narrow it down to one thing that triggers it. It's very annoying seeing how it's brand new.
