Hi, I want to know how to change these grey windows that shows up when pressing any in-app button, I want the Bubble kind effect like on newer Android versions, I'm on an Xperia E4 running KitKat 4.4.4, I already managed to change the the stock rom's default touch sound, and that is what's making me think that it is possible to do such thing. The attachments are screenshots helping you understanding what I wanted to describe. Thanks in advance!
