This is not a drill: the future of Samsung software is already here. A brand new One UI 8.5 build has just been spotted for the Samsung Galaxy S25 Ultra US in the United States. While the stable One UI 8 update is still rolling out to many devices, the discovery of this new build shows just how fast Samsung is moving. The appearance of the build—with version number S938USQU5CYI4—confirms that Samsung is hard at work on its next big software update.
What is One UI 8.5?
A point update, like One UI 8.5, might seem minor. But in reality, it’s often where Samsung rolls out its most important new features, especially for its flagship phones. These updates often bring key new camera tools, performance fixes, and, in this case, a whole lot of AI. It’s a way for Samsung to give its latest devices a major boost before the next big OS change.
One of the biggest rumors about One UI 8.5 is the addition of a major new AI feature: automatic call screening. This feature is said to be similar to Google’s popular Pixel Call Screening. It would use an AI assistant to automatically answer and transcribe calls from unknown or spam numbers, giving you a chance to see what the call is about before you even pick up.
Leaks also suggest that One UI 8.5 will bring a big redesign to Samsung’s apps. The Settings app, Phone app, and Device Care are all getting a makeover with new, cleaner layouts and a more modern look. Some of these changes are even being compared to Apple’s latest designs.
This early build is a big deal because it confirms Samsung’s fast-paced update schedule. The company seems determined to avoid the delays of past years and get its new software out to its flagship devices as quickly as possible. This is great news for fans who don’t want to wait months for new features.
The fact that the build was spotted on the Galaxy S25 Ultra makes sense. Samsung always uses its latest flagship phones to test new software before it moves on to other devices. This helps them find and fix any bugs before a wider beta program is even started.
While we’re all excited, it’s important to remember that this is an early internal test. A public beta program for One UI 8.5 is still likely a few months away. But with Samsung working so quickly, we might see something much sooner than we think.
