Samsung Galaxy S26 series receives third One UI 9 beta update

Samsung Rolls Out One UI 9 Beta 3 for the Galaxy S26 Series

If you’re currently testing the waters with Samsung’s early software builds, there is some good news. Samsung has just released the third beta for One UI 9, based on Android 17, for the entire Galaxy S26 lineup. This latest update follows two previous versions released last month and brings a much-needed layer of polish to the user experience.

The update is a substantial one, weighing in at about 1.7GB. It is currently rolling out to users in South Korea, India, Poland, and the UK. Whether you’re using the standard S26, the S26+, or the top-tier S26 Ultra, this build—identifiable by firmware versions ending in ZZF7—aims to squash several bugs that early adopters have been reporting.

What’s Fixed in This Update?

Beta software is notoriously buggy, but this third iteration focuses on stability and refining core features. Here are the most notable fixes included in the changelog:

Photography & Zoom: Samsung has improved focus accuracy when using the 30x zoom and fixed a glitch that caused the camera preview to appear cropped.
Lock Screen Widgets: Issues with weather and battery widgets failing to update on the lock screen have been resolved.
Navigation Fixes: A frustrating bug where the home screen wouldn’t swipe while using the S Pen has been addressed, along with a fix for scrolling issues in the “My Files” app.
Display Glitches: No more random white screens when receiving calls or black backgrounds appearing when you pull down the status bar.
System Stability: A critical fix was included for an issue that caused devices to reboot unexpectedly during video streaming.

How to Update Your Device

If you are already enrolled in the One UI 9 beta program, you should see a notification soon. If you want to grab it right away, you can manually trigger the download by navigating to Settings > Software update > Download and install.

As always with beta software, it is a smart move to back up your important data before proceeding. Each of these updates brings us a step closer to the official, stable release of Android 17 for the Galaxy family later this year.
