Hello, I'm Marco and I'm here to report a bug that noone have osserved in new releases.
This bug affects every iphones since 9.2 firmware, but it was no present in 9.1
It's a cosmetic bug that appear when you tap a voice in settings, for example Facebook, Flickr but also battery, phone, messages and so on. (Not happens in wifi, blueetoth,notifications and the first voices of settings)
The first time you tap a voice, there is not a smooth slide into the new page, but the principal settings page moves up or down like a little jump. So the transitions is not smooth and you can see it every time you enter for the first time into a menu. Second time is smooth but it's enough close setting and open it again to see the bug when tapping a voice.
