Overview
- Samsung has begun wider One UI 9 testing in mid‑June 2026 by issuing a third Android 17 beta to Galaxy S26 owners that targets UI, camera and stability bugs and includes the June security patch.
- A One UI 9 firmware for the budget Galaxy A16 5G was seen on Samsung’s internal European test servers under build A166BXXU8EZF1, indicating internal testing is extending beyond flagships.
- Reports say Samsung will likely skip a public beta for entry‑level phones like the A16 5G and deliver the stable Android 17 update directly after internal validation.
- Samsung published its June 2026 security update that fixes up to 45 vulnerabilities across Android 14–16 Galaxy devices, including several local‑attacker bugs, and security researchers urge prompt installation.
- Samsung is staging One UI 9 rollouts regionally with flagship devices first and expects to debut the stable release on its next foldables before phasing updates to other models later in 2026.
