Samsung One UI 9 beta 7 draws complaints ahead of wider rollout
Samsung‘s latest One UI 9 beta has triggered complaints from Galaxy S26 Ultra users over performance issues, adding pressure on the company to resolve glitches before the Android 17-based software reaches a wider range of devices.
The seventh beta build has been criticised for introducing micro-stutters that some testers say were absent from the previous version. Tarun Vats, a Samsung software insider, said Beta 6 had been the smoothest version he had used on his Galaxy S26 Ultra, while Beta 7 introduced problems when typing, switching between the Quick Settings and notification panels and navigating interface animations.
Why, Samsung, why do you always do this with every beta program?

Beta 6 (ZZHE) with One UI Home v18.0.07.39 was probably the smoothest and most fluid experience I've had on the S26 Ultra.

Ice Universe, another prominent Samsung-focused insider, also criticised the latest build and suggested that Samsung’s software performance had deteriorated as the stable release approached. Both insiders subsequently said they had returned their Galaxy S26 Ultra devices to Beta 6 after finding the newer build less responsive.

The complaints are particularly notable because Beta 7 arrived only days after Samsung released Beta 6 and shortly after the company added several major features to the One UI 9 testing programme.
One UI 9 expands beyond the Galaxy S26
Samsung released the latest feature update for One UI 9 beta users on August 28. The update introduced My FanCam, an AI-powered tool that can track a selected person in a video and automatically reframe footage for different aspect ratios.
The same release expanded Now Brief, which presents personalised information and recommendations in customisable cards. Samsung also added security and privacy information to the feature and improved Now Nudge to provide more context-sensitive suggestions.
One UI 9 is based on Android 17 and initially entered beta testing with the Galaxy S26 series in May. Samsung’s first beta programme included new tools for personalisation, creativity, accessibility and security.
The Galaxy S26 series is no longer the only hardware associated with the software. Samsung’s recently announced Galaxy S26 FE ships with One UI 9, making it the first model in the S26 family to receive the stable software ahead of the flagship S26, S26 Plus and S26 Ultra.
Samsung is also preparing to extend One UI 9 to older Galaxy devices. Reports indicate that the company plans to bring the new software beyond the S26 family, with 18 smartphone models expected to be included in the next stage of the rollout.
Beta 7 puts final release under scrutiny
Tarun Vats has urged Galaxy S26 users experiencing similar micro-stutters to report them through the One UI 9 beta forum. He compared Beta 7 build ZZHK with Beta 6 build ZZHE and asked other testers to report whether they were encountering the same behaviour.
Galaxy S26 Fam,

I’ve reverted back to ZZHE (Beta 6) and decided to stay on this build until the One UI 9.5 Beta arrives in December. I won’t be updating my phone anymore.
Thanks, Samsung, for ruining the experience. 😑

The Galaxy S26 series is currently receiving Beta 7 in markets including South Korea, Germany, India, Poland and the United Kingdom, with the United States expected to follow. The roughly 1.2GB update also includes the August 2026 security patch and additional AI features.
