No more peeking: Samsung closes the door on early One UI leaks
For months, curious devs got a sneak peek at Samsung's secret software — but the party's officially over.

We all know that the world of mobile tech is full to the brim with leakers, who get their hands on whatever companies try to hide about upcoming products or releases. And as much as we love these leakers (the hype about new stuff is real), companies don't particularly like them.
Over the past few months, a lot of One UI 8 firmware builds (internal ones) have been leaked for multiple models of Galaxy phones. This gave us a very detailed early look at what Samsung was planning in terms of software. Well, it seems this won't happen again, at least not this way.
A few months ago, a curious dev found a way to locate and download under-development One UI firmware files. These files were meant for Samsung's internal testing. And this is what brought us early looks over One UI 8 for the Galaxy S25 Ultra, Z Flip 6, and Fold 6.
Now, the folks at SamMobile confirm that, unfortunately, for all the curious folks who want to see early builds, Samsung has fixed that loophole that allowed people to access its internal test server. That server was used to send software updates for Galaxy phones, tablets, and smartwatches, but for internal testing.
Now, unless someone else manages to find another loophole, these internal One UI firmware files can't be accessed. So yep, this pretty much means not to have any hopes of seeing early builds of One UI 8.5, which may come with the Galaxy S26 series.
Also, we won't be able to know, at least not in this way, new software features under development for Samsung's devices.
Of course, you can still download publicly released firmware files; this has nothing to do with the usual downloads for firmware (the official ones).
And also, beta builds will continue to exist to give people an early look (officially) at new builds of One UI. So we're likely going to see One UI 8.5 before it releases with the Galaxy S26, because it will likely first be beta tested on the Galaxy S25 phones.
