Samsung is rolling out the fourth One UI 9 beta update for the Galaxy S26 series. Multiple outlets report the update is delivered over the air to users enrolled in Samsung’s beta program and comes in at roughly 1.25GB. The release follows the third beta, which Samsung issued about a month earlier, and is described as targeting issues affecting global users ahead of a stable rollout.
GSMArena reports the update appears to be available first in India, with a firmware version ending in “ZZG4,” while Android Authority describes it as being aimed at users in various regions. Both sources indicate the update focuses on bug fixes related to user-interface components and routine system behavior, including problems connected to the clock size and elements of the Quick Panel, navigation bar, and timers. Android Authority also notes the update includes July security patches.
Overall, the fourth beta continues Samsung’s iterative testing process for One UI 9 on the Galaxy S26 line, with incremental improvements and security updates provided to beta participants as the company prepares for a stable release.
