Quick Settings Panel Overview auf OnePlus
The quick settings panel on OnePlus phones bundles frequently used system toggles into a single overlay, so you do not need to open the full Settings app for every change. It sits above the notification shade and is controlled by the same system service that manages notifications and status bar icons.
To open it, Swipe with two fingers to open the quick settings. A grid of icons appears right away, each one representing a function such as Wi-Fi, Bluetooth, flashlight or airplane mode. Tap any icon to Enable or disable the desired function/feature without leaving the screen you are on.
A single tap switches most functions on or off. A long press on many icons opens the related settings page instead, which is useful when you need finer control, for example choosing a specific Wi-Fi network rather than just switching Wi-Fi on in general.
If an icon looks greyed out or unresponsive, the underlying function might be blocked by another active setting, such as airplane mode disabling mobile data or Bluetooth. Disable the blocking function first, then try the toggle again.
Use the full Settings app instead of the quick panel when you need detailed options, like a specific saved Wi-Fi password or a custom brightness curve, since the panel only offers a basic on/off switch.
