Samsung has kicked off internal testing of the July build of One UI 8.5 for its Galaxy S24 lineup, with a test firmware already spotted on company servers for the Galaxy S24 Ultra. Firmware insider Tarun Watts reported the build number S928BXXS6DZG1, confirming that this interim update is moving beyond mere rumors.
This latest build follows an earlier test version labeled S6DZF2. Samsung hasn’t released an official changelog yet, but July updates typically focus on boosting system stability, improving performance, and patching security vulnerabilities. This is consistent with Samsung’s promise to provide up to seven years of Android OS and security updates for the Galaxy S24 series-an unusually long support window for Android flagships.
Meanwhile, Samsung is already testing more recent firmware versions. One UI 9 has appeared in trials on several Galaxy A series phones, including the A57, A56, A15, and A07. This staged rollout approach is familiar: flagship models get refined incremental updates first, while mid-range devices prepare for the next major One UI release. If the pace holds, the public rollout of One UI 8.5 for the Galaxy S24 could begin within the next few weeks, following the typical pattern of builds appearing first on internal servers before reaching users.
For context, Samsung’s Galaxy S24 series competes in a crowded flagship market dominated by Apple and Google, both of which also emphasize longer software support-Apple with up to seven years of iOS updates and Google expanding its policy to five years on Pixel devices. Samsung’s commitment to seven years of updates, combined with frequent incremental upgrades like this one, helps it stay competitive globally while fostering loyalty among power users.
Next up is watching how Samsung balances delivering steady One UI refinements with the jump to One UI 9 across its device range. The Galaxy S24’s early access to patches will be a key test of Samsung’s promise for extended support-any delays or issues here could raise doubts about the company’s update strategy as it faces intensifying competition.
