One UI 7 is one of the biggest software upgrades for Galaxy devices in recent years. It was released with the Galaxy S25 series at the Galaxy Unpacked event in January. The newest flagship phones running One UI 7 pack a host of software goodies, including several Galaxy AI features such as Now Bar, Now Brief, and more. Since these features were unveiled alongside One UI 7, many (including some of us at Gizmochina) assumed they would also roll out to older Galaxy devices with the update. But that won’t be the case as some Galaxy AI features may remain exclusive to the Galaxy S25 series.
Sally Jeong, EVP and Head of Framework R&D at Samsung MX, revealed some interesting details about the One UI 7 software in a recent interview published by Samsung Indonesia. She said that planning alone took more than two years before development even started. This is probably the biggest reason behind the significant delay in the release and rollout of One UI 7.
During the interview, Sally was asked about the role of NPUs and GPUs in powering these new AI features on the Galaxy S25, and the response was quite surprising. Samsung’s AI features can be divided into two categories: those that rely on on-device hardware and those that rely on the cloud. Sally said the “Personal Data Engine” in One UI 7 that powers features like Now Brief requires advanced chipsets and hardware like the Snapdragon 8 Elite on the Galaxy S25 series.

Sally also mentioned that cloud-based AI features, such as Circle to Search, are easier to roll out to a wide range of Galaxy devices. But for deeper on-device AI experiences, powerful hardware is required. This means some AI features that require extensive on-device processing might not come to older Galaxy devices after installing One UI 7.
The Samsung executive didn’t specify which Galaxy AI feature won’t make the cut to older Galaxy devices, nor did she reveal details about the ineligible devices. Now Brief could be one of them, which has, so far, not been seen in the One UI 7 betas for the Galaxy S24 series, as spotted by Android Police.
We’ll get to know more as and when One UI 7 starts rolling out, which is already too delayed. Samsung still hasn’t announced the rollout plans. If leaks are anything to go by, we shouldn’t expect it anytime soon, at least before April. You can read more about it in our One UI 7 section.
