Native Page transitions not so smooth on android 4.2 ! Super smooth on the Kit Kat ! why?

Why are native trasitions not so smooth on Jellybean ! They were smooth on kitkat butter smooth !

Compared to ionic transitions native are smooth on JB… but everytime the view/state opens the nav icon in nav-bar appears to be hovered/selected ! Like hover-color is blue and after clicking anywhere it disappears !
happens only in jellybean !

Any solution ?
