28. What are Window Animation, Transition Animation, and Animator Duration Scale in "Developer Options"?

A: As you may well know, all android phones display animation regardless of make or manufacturer. While these animations make the phone's UI appear slick, they sorta waste time — especially on faster phones, which could switch between apps instantly if not for the animations. When we disable the animations, it speeds up navigation between different apps and interface screens on your phone, saving you time and making the phone to seem faster.

Window Animation Scale- Refers to the speed of the animation when a new window opens

Transition Animation Scale- Refers to the speed of animation when transitioning between apps

Animator Duration Scale- Refers to the speed of animation when you press the app tray button or other related items. (This takes effect only after you've restarted the launcher. No effect on custom launchers though)

However, if you turn all these off, you'll lose smoother transition effects but gain a speedier phone.
