Samsung One UI 7 Adds Hidden Depth to Brightness and Sound Sliders

Samsung adds hidden expanded menus for brightness and audio, giving users faster control with just a long-press


One UI 7 Redefines Quick Panel Functionality

Samsung’s One UI 7 introduced a revamped Quick Settings and Notification Panel, enhancing both design and functionality. But beyond the surface-level UI updates, Samsung tucked in two hidden features that offer deeper control — all within a single tap-and-hold.

  • The Quick Panel card includes a Brightness Slider, Volume Slider, Dark/Light Mode toggle, and Sound Mode switch.
  • What many users don’t realize: long-pressing the Brightness or Volume sliders unlocks expanded control panels.

Hidden Feature #1: Expanded Brightness Settings

You likely use the brightness slider frequently — even with Adaptive Brightness turned on. But now, One UI 7 offers a quick shortcut to advanced brightness controls:

  • How to Access: Tap and hold the Brightness Slider in the Quick Panel.
  • What You’ll See:
    • Full-size brightness slider
    • Toggle for Adaptive Brightness

This quick-access method saves you from diving into full Settings, making real-time screen tuning much faster.


Hidden Feature #2: Sound and Effects Shortcut

The audio slider is even more feature-packed. Holding it opens the new Sound and Effects menu — a central hub for advanced audio tuning:

  • How to Access: Tap and hold the Volume Slider in the Quick Panel.
  • Available Controls:
    • Main Speaker Volume slider
    • Dolby Atmos options: Off, Auto, Movie, Music, Voice
    • Equalizer presets: Balanced, Bass Boost, Smooth, Dynamic, Clear, Treble Boost, Custom
    • Loudness Normalization toggle

These tools make it easy to fine-tune your audio experience, whether you’re watching movies or listening to music, without navigating deep into system menus.


Why These Hidden Features Matter

Unlike the Dark Mode or Sound Mode buttons, which only redirect to their main Settings pages, these slider expansions open instantly, giving you functional controls on the fly.

  • Efficiency: One tap holds more power than ever.
  • Customization: Tailor display and sound to your environment with minimal effort.
  • Consistency: Both hidden menus maintain the aesthetic and responsiveness of One UI 7.
