Samsung is rolling out another Android 12-based One UI 4.0 beta update to the Galaxy Z Fold 2. This is the third beta build for the 2020 Galaxy foldable and it comes with a bunch of bug fixes and improvements. Identified by build number ZUKK (via Sammy Fans), the latest update is currently rolling out to users in South Korea but should soon make its way into other markets as well.
According to the official changelog, the most recent One UI 4.0 beta update for the Galaxy Z Fold 2 fixes the issue of fingerprint authentication not working properly in some apps. It also fixes an issue with screen brightness automatically changing to the lowest level when the device is on boot. The Galaxy A Z Fold 3 and Galaxy Z Flip 3 also had similar brightness issues on One UI 4.0 beta. Samsung has fixed it with a recent release.
Other issues fixed on the Galaxy Z Fold 2 include the lack of visual effects with quick toggles, unstable Windows PC connection via USB, heavy battery drain when connected to the Galaxy Watch 4, lock screen issues with the Galaxy Watch 4, and navigation bar errors.
The changelog doesn’t mention any new features. This suggests that Samsung is getting closer to releasing the stable One UI 4.0 update to the Fold 2. The Galaxy S21 series received four beta builds before picking up the stable release. It’s quite likely that the second-gen Samsung foldable will also follow a similar path. In that case, One UI 4.0 could release publicly for the phone before the end of the year, at least in some markets. We wouldn’t be surprised though, that’s how impressive Samsung’s software game has been lately.
Samsung is rapidly moving through its One UI 4.0 beta program
Samsung may have released the stable One UI 4.0 update to only one device so far (Galaxy S21 series). But the company is rapidly moving through the beta program for a bunch of other devices. Along with the Galaxy Z Fold 2, the Korean firm is also currently beta testing the new software for the Galaxy Z Fold 3, Galaxy Z Flip 3, Galaxy Z Flip, Galaxy S20 series, and the Galaxy Note 20 series. It also recently opened the program to the Galaxy Note 10 and Galaxy S10 series.
Most of these devices have already received multiple beta builds. So Samsung could soon start pushing the stable One UI 4.0 update to them. We will let you know when the rollout begins.
