One UI 5.1 is here for Galaxy Z Fold 4 and Flip 4 in the US

One UI 5.1 is here for Samsung‘s latest foldable in the US. Both carrier-locked and unlocked variants of the Galaxy Z Fold 4 and Galaxy Z Flip 4 are getting the new One UI version stateside. The company began the rollout in international markets last week.

The One UI 5.1 update for the carrier-locked Galaxy Z Fold 4 in the US comes with the firmware build number F936USQU1CWAC. That for the unlocked units is F936U1UEU1CWAC. As of this writing, the update is only available for users on AT&T, Comcast, Xfinity Mobile, Nextech, Bluegrass Cellular, US Cellular, and Cricket Wireless networks. But Samsung should soon cover devices on other networks too.

The story is similar for users of the Galaxy Z Flip 4 as well. Cellular South is the only additional carrier on which Samsung’s fourth-gen clamshell foldable is picking up the new update. But as said before, the Korean firm shouldn’t take long to bring One UI 5.1 to users on other networks. The updated firmware versions for this phone are F721USQU1CWAC (carrier-locked) and F721U1UEU1CWAC (unlocked).

One UI 5.1 reaches the latest Galaxy foldables in the US

The latest update for the Galaxy Z Fold 4 and Galaxy Z Flip 4 in the US brings the February security patch. This month’s SMR (Security Maintenance Release) from Samsung patches more than 50 vulnerabilities, including a handful of critical ones.

However, we are more interested in the content of One UI 5.1. While it may seem like a minor upgrade from One UI 5.0 that both foldable are currently running, the new release contains plenty of goodies.

For starters, Samsung has added a shortcut to Expert RAW in the stock camera app. You can now quickly switch to the professional-grade camera app (separate download) if the stock solution isn’t good enough for you.

One UI 5.1 also brings improvements to the multitasking experience on the foldable with new gestures and improved DeX. Samsung Notes, Bixby Text Call, AR Emoji, Samsung Keyboard, and other services get substantial functional improvements too. You can find Samsung’s full One UI 5.1 changelogs here (Galaxy Z Fold 4) and here (Galaxy Z Flip 4).

It’s pertinent to mention here that One UI 5.1 is causing battery drain for some users. Samsung hasn’t said anything about the issue, though. At least not yet. But you might still want to wait a few days and see if the company releases an official statement about this before installing the update. As usual, you can check for updates from the Settings app. Go to the Software update section and tap on Download and install.
