Why does my iPhone 6 do this? - 1

My iPhone 6 does this when you double tap the home button not pressing the home button but lightly putting your finger on it, is it a feature that apple have yet to do up a bug anyone getting this?Why does my iPhone 6 do this - 2

I don't know if the regular six does it but the six plus does that. It's because the phone is so big and if your holding it with one hand a double press the home button the apps will lower so it's easier to reach with your thumb. You can go into settings>general>accessibility and fix it

I have the iphone 6 and mine does that too. The 6 and 6 plus both do it because it's a feature to be able to reach the top apps with one hand since the phones are large
