This method enables you to power off your Vivo device directly from the software interface, eliminating the need to rely solely on physical buttons. This option might not be available on all Vivo models or software versions.

• Swipe Down: From the top of your screen, swipe down twice to access the Quick Settings panel.
• Look for the Power Icon: Locate a small power icon (often a circle with a vertical line), typically found in the top right or bottom right corner of the Quick Settings panel.
• Tap the Power Icon: Tap this icon, and the power off menu will appear.
• Select “Power Off”: Choose “Power off” to shut down your phone.

Remember to save any unsaved work before powering off your device. If you encounter any issues, ensure your phone’s software is up to date, as updates often include bug fixes and feature improvements.
