I notice when playing with friends xiaomi mi3. When bring up the keyboard, there is a nice animation where the keyboard slides up.

On note 3 it just burst into the screen. I thought it's a SwiftKey bug. After reading this thread only realize Samsung remove it on newer touch wiz. Duno why. Anyway can use this xposed module to get it back. Now my keyboard slides into appearance smoothly.

share here cos it works for note 2 too
