Oppo: Change Smart Sidebar Opacity

The Smart Sidebar handle on Oppo phones sits at the edge of the screen and defaults to a solid opacity level. In fullscreen games, video apps, or split-screen layouts, that solid bar can cover icons, subtitles, or interface elements underneath it.

Coloros lets you lower or raise this opacity so the handle blends into the background instead of standing out. The control lives inside the sidebar tools rather than the general display settings, which is why many people overlook it.

To change it, go to Tap on Settings ➔ Tap on Convenience tools ➔ Tap on Smart Sidebar ➔ Set the Floating bar opacity. Drag the slider until the handle reaches a transparency level that still stays visible but no longer blocks content behind it.

This adjustment only changes the visual opacity of the handle. It does not affect which apps appear inside the sidebar, nor does it change how sensitive the edge gesture is for opening the panel. If the handle becomes hard to find after lowering opacity too far, raise the slider back up until you can tap it reliably.
