I recently got my new iPhone 7+ and I am loving it. But I have encountered this thing that I don't know what's it's used for and so it annoys me to no end. When ever I double tap my home button everything in my screen with shift downward and it will just display my home screen background? If anyone knows what this is, or knows how to use it. I would love to find out. - Photo attached of what I mean. Thanks --- Post Merged, Oct 1, 2016 --- Edit - it's not a double click more of tap lightly.
