Samsung kicked off the Android 14-based One UI 6 Beta program about a month ago, and the latest device to get a taste of it is the Galaxy A54.
Those interested can enroll in the One UI 6 Beta program from the Samsung Members app on their Samsung Galaxy A54. Once the application is accepted, the One UI 6.0 beta update can be installed by heading to the phone’s Settings > Software update menu.
However, since this is a beta version, it’s best avoided on a primary device because beta software often has bugs that can hamper the user experience.
The One UI 6.0 beta update for the Galaxy A54 is currently available in South Korea, but other markets should get it soon.
