Galaxy Z Fold 4 and Galaxy Z Flip 4 owners can now make their phone more secure thanks to the latest update that's rolling out this week. The new update is rolling out to the Galaxy Z Fold 4 and Flip 4 in the US, Europe, and some Asian markets.
If you have a Galaxy Z Flip 4 or Fold 4, you can check for the new update on your device by opening its Settings app, navigating to the Software update submenu, and tap Download and install. You can also download the latest firmware for these foldables from SamMobile.
Samsung is rolling out an improved version of the Auto Blocker feature with the November 2024 update for Galaxy devices, in addition to the latest security fixes. Auto Blocker, introduced with One UI 6.0/Android 14, is designed to improve security by, among other things, preventing installation of apps and software updates and sending of commands using a USB cable.
Once the November update is installed, enabling the Maximum restrictions option in Auto Blocker will stop any USB devices except chargers from working. For some reason, this enhanced and more secure version of Auto Blocker wasn't included with the One UI 6.1.1 update, but it will likely be made available on several devices over the next few weeks.
