Use Display Assistant in Good Lock to speed up screen brightness changes and enhance everyday usability
Smoother Brightness, Instantly
Samsung’s Adaptive Brightness feature automatically adjusts your screen based on ambient lighting. But if you’ve ever found those changes too slow or slightly laggy, there’s a hidden setting that can speed it up by 4x—making the transition feel faster and more natural.
Why This Matters
Screen brightness adjustments happen hundreds of times daily—often without us noticing. By accelerating the speed at which your phone responds to changing light conditions, you’ll experience:
- Less visual delay in dark-to-light transitions
- A more responsive and fluid screen experience
- Better performance outdoors and in fluctuating environments
Even users who previously avoided Adaptive Brightness may find the faster version far more usable.
Requirements
To unlock this hidden feature, you’ll need:
- A Galaxy phone that supports Good Lock
- The Display Assistant module installed
Good Lock is Samsung’s official personalization suite and is available on flagship, upper mid-range, and select budget devices.
