The Android 16 update enters broad public testing with the September 2025 security patch.

Overview

  • Beta access now spans the Galaxy S23 lineup and mid-range Galaxy A55, A54, A36, and A35, with the Z Fold 5 and Z Flip 5 joining in South Korea.
  • The S23 beta is live in India and South Korea, with availability confirmed in the UK and wider regions expected next.
  • Test builds add a redesigned Samsung Internet, a revamped Quick Share interface, new Samsung DeX rotation and resolution options, and stronger Secure Folder protections.
  • The first S23 beta omits the Galaxy AI feature Now Brief, which recently reached the S24 in beta, and its availability on S23 remains unconfirmed.
