To do this is a little complicated but some of the steps are worth it. You have to enable Developer Options on your phone. Once you've done that, you can eliminate all animations on your screen.
For Developer Options: Go to Settings and and then to About device. Scroll to the bottom of About device till you come to Build number. Tap on this seven times and you have now enabled Developer options in Settings.
In Settings search for Developer options and scroll till you get to Windows animation scale and then tap on it and set it to off.
You will notice your phone is also slightly zippier when you have done this.
