Galaxy Z Fold 4 or Galaxy Z Flip 4 owners can now make their phones more secure with the latest update, which is rolling out to the two phones in the US, Europe, and some Asian markets.

If you own a Galaxy Z Flip 4 or Fold 4, you can manually check to see if the update has arrived on your device by opening the Settings app, navigating to Software Update, and selecting Download and Install.

Samsung is improving the Auto-Block feature with the November 2024 update for many Galaxy devices. Auto-Block โ€“ introduced in One UI 6.0 โ€“ is designed to improve security by preventing app installation and updates from unknown sources, sending commands over the USB cable, and more.

After installing the November update, you can enable Restricted mode to disable all USB features except power transfer. For some reason, this new version of Auto-Block does not come with the One UI 6.1.1 update.
