Galaxy Z Flip 4, Z Fold 4 get May 2023 security update

Earlier this week, Samsung released the May 2023 security update to several Galaxy Z series phones, including the Galaxy Z Flip 4 and the Galaxy Z Fold 4. However, the update was released only to the unlocked variants of the foldable phones. Yesterday, the update was released to the carrier-locked versions in the US. Today, the new security update is available to the global versions of the Galaxy Z Flip 4 and Galaxy Z Fold 4.

The May 2023 security patch included in this new software update brings fixes for over 70 security flaws found in Samsung phones. Some of those flaws were marked as critical, so we are glad that they've been fixed to make the Galaxy Z Flip 4 and Galaxy Z Fold 4 more secure and reliable.
