An Android setting buried in the developer options menu can make a phone feel noticeably faster, according to Engadget. Users can find the hidden menu by tapping the Build Number seven times, then adjust Window animation scale, Transition animation scale, and Animator duration scale to 0.5x. That makes most system animations play twice as fast.
Engadget stresses that this does not improve actual performance. It only changes perceived responsiveness, making actions like unlocking the phone and switching apps feel snappier. The publication notes that animations also mask loading times, so halving them can backfire on budget devices where menus and apps cannot load quickly enough to keep up.
The effect varies by Android skin. Google's Pixel UI has more drawn-out animations, so the tweak makes a noticeable difference, while OnePlus's OxygenOS is already faster by default. The source also notes that disabling Developer Options resets the animation settings to their defaults.
