Your victim's Android phone normally performs like this:
But you can make it run crazy slow like this:
Go to your phone's settings and find the "About phone" option. It's at the very bottom of the list on most Android phones.
Then scroll down to "Build number," and tap it repeatedly until it tells you "You are now a developer!"
Now tap the back button on your Android phone to go back to the Settings menu and you'll see a new option called "Developer options" right above "About phone. Tap it.
Scroll down till you find the "Window animation scale," "Transition animation scale," and "Animator duration scale."
Tap each option and set the scales from the default from 1x to 10x.
And now the phone will behave extremely slowly:
To reverse it, go back to the Developer options in Settings and reset the animation and duration scales back to their defaults (1x).
