Change this Android setting to instantly give your phone twice the speed

To access the animation speed settings, you'll first need to enable Developer options. Developer options contain a list of performance and UI-specific settings that are typically hidden by default as they're intended for, drum roll, developers!

To enable it, open up your Settings > scroll down to About phone > tap on Software information > and then tap your Build number seven times. If this is your first time doing so, your phone should display a ticker that tells you how many more times you need to tap the text.

If done successfully, Developer options will now be enabled, which you can access by going back to your default settings page and navigating to the bottom of the list.

Now that you've cracked the code to get into the Developer options, you'll be presented with a long list of settings, toggles, and switches. Don't be intimidated; we're only here for one thing, and that's the "Drawing" section. Scroll down the list until you find it.

From there, you'll see three animation scale settings:

Tap on each one and change the scale rating from 1x (default) down to .5x. The lower the number, the faster the time it takes for the animation to perform. 

If you don't want any animations on your phone at all, you can also set the value to "off".
