Urgent update from Samsung for Galaxy S26 users: Install immediately
Having initially released the One UI 9 update to the Galaxy S26 family, Samsung is now continuing to release security updates for its latest flagship models. As the end of October approaches, the tech giant has rolled out a second security patch for its flagships.
The South Korean company has started distributing a second software update in October for the Galaxy S26, Galaxy S26+, and Galaxy S26 Ultra models. Released in Korea, the new version is considered to have been pushed out off-schedule to fix a critical issue in the system. In other words, an unplanned update was released because a major problem was detected, so it is advisable to download and install this update immediately.
Tech giant Samsung did not provide a detailed explanation of what changes the package brings. However, according to information reported by tech media outlet SamMobile, the new version maintains the same security patch level as the previous update.
New update for the Galaxy S26 series
The update in question first reached devices in Samsung's home country of South Korea. According to data shared by a user named Kailash on the X platform, the update has a download size of 580.37 MB.
The build number of the update was recorded as S94xNKSU5BZJB. The rollout is expected to be gradually made available to users in other countries in the coming days.
