Here is a simple way to make your phone more snappy.

Step one *

Go to settings : About phone : Software information : Click on build number 7 times, you will unlock developer option.

Step two*

You will find developer option on the bottom of your settings menu.

Enter - 

Step three*

Scroll down on developer option until you find window animation scale. The default settings will be at 1x. Before making any changes, just check the smoothness of your phone by opening application, settings tabs etc to feel the current smoothness, then change the settings to 5x 

Now change to 5x scale 

Now, you will feel your phone's animation feel snappier than before.

*THERE ARE SO MANY OPTIONS UNLOCKED IN DEVELOPER OPTIONS. DO NOT TRY ANY OPTION THAT YOU ARE NOT AWARE OF, AS IT MAY LEAD TO A PRIVACY RISK.

That's always good to change the animation scale. However, we have to keep in mind that some banking apps don't work with developer option enabled.
