Samsung Galaxy S23 Ultra software update
Samsung has released a new software update for the Galaxy S23, Galaxy S23+, and Galaxy S23 Ultra units enrolled in the One UI 9.0 (Android 17) beta program in its home country, South Korea.
It has a size of 388.60MB and firmware version S91xNKSU8ZZI9. The brand says that this is a hotfix update, a small update released outside a normal schedule to fix a critical bug or security flaw.
According to the changelog, it brings only one change: “Applied security-related stabilization code” (via Tarun Vats).
The company may or may not release the latest One UI 9.0 beta update for the Galaxy S23 series in other countries.
You can check for its availability and get it by going to Settings > Software update > Check for updates.

I’m a computer science engineer living in Hyderabad, India, who has a keen interest in automobiles and consumer electronics. My journalism career kicked off in 2017 with MySmartPrice where I wrote news, features, buying guides, and explanatory articles about technology among other things, and reviewed many products, including smartphones, tablets, laptops, PC components, smartwatches, audio devices, wearables, and smart home products. Since then, I have worked for 91Mobiles, Apple, and Onsitego, before finally landing on SamMobile.
