Step 1: Enable developer options on your device.
Look for the Developer options in the Settings menu and enable them. If you don’t see a Developer options entry in the menu, head to the About device area and tap on the Build number until you see a message saying that they have been enabled.
Find the settings for animations in the Developer options.
Step 2: Turn off the animations (or reduce them).
Scroll down to the Window animation scale, Transition animation scale, and Animator duration scale.
Step 3: Restart your device.
Try moving between a few apps and there should be a noticeable difference in how quickly your device handles them.
