The Galaxy Z Fold 6 and the Galaxy Z Flip 6 units for Korea, which have model numbers SM-F956N and SM-F766N, are getting new software updates. They bring the April 2026 security patch, which fixes 47 security issues present in the previous version of the OS, making these phones more secure. The updates for both phones carry firmware versions ending with CZCS.
Samsung should release the April 2026 security patch for the Galaxy Z Fold 6 and the Galaxy Z Flip 6 in other countries in the next few days. To check their availability in your region, go to Settings > Software update > Download and install. Once the brand releases them, we will make them available in our database for you to download and install them manually using your PC.
Recently, Samsung released the beta version of One UI 8.5 (Android 16 QPR2) for the Galaxy Z Fold 6 and the Galaxy Z Flip 6, letting their users try the new software before the brand releases its stable version in the next few weeks.
Compared to One UI 8.0 (Android 16), One UI 8.5 offers a user interface that looks cleaner and more sophisticated and is more customisable. Compared to the previous software, the new one also brings many new features.

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.
