Earlier this week, Samsung released the May 2023 security update to several Galaxy Z series smartphones, including the Galaxy Z Flip 4 and the Galaxy Z Fold 4. However, back then, the update was only released to the unlocked versions of the smartphones. Today, Samsung has released the update to the carrier-locked version of the Galaxy Z Flip 4.
The latest software update for the Galaxy Z Flip 4's carrier-locked version comes with firmware version F721USQS2CWD9 in the US. The new software is currently available on Metro PCS' and T-Mobile's network in the US. More network carriers could release the update over the next few days.
