Samsung is testing One UI 8 on older devices, but Galaxy S21 users may not receive certain features.

New report claims Samsung is moving quickly with One UI 8 testing on various smartphones and tablets.
The Galaxy Z Fold 7 and the Galaxy Z Flip 7 smartphones from Samsung will come with One UI 8. This new software has been in beta testing on the Galaxy S25 since May. In early August, the beta became available for the Galaxy S24, Z Fold 6, and Z Flip 6. Samsung has announced plans to release the One UI 8 beta for additional devices, including the Galaxy S23, Galaxy Z Fold 5, and Z Flip 5.
One UI 8 features a redesigned visual style, new icons, refined animations, and uniform menus. The software also includes enhanced performance and better AI integration.
The release of One UI 8 is an important one for Samsung, as the delayed release of One UI 7 raised questions about the company's software update schedule. Apple's iOS 26 developer and public beta releases and its Liquid Glass redesign seem to be on schedule.
