The Samsung Galaxy A15 5G (also known as Galaxy Buddy 3) made its debut in 2023 with Android 14 (One UI 6), and at that time, the company promised four major OS upgrades for the device.
Fulfilling its commitment, Samsung has released the One UI 8.5 update (Android 16-based) for the Galaxy A15 5G device in South Korea.
Samsung Galaxy A15 5G: One UI 8.5 update
The update arrives in South Korea, with the build version A156LKSUADZE9/ A156LLUCADZE9/ A156LKLUADZE9. The update comes with the May 2026 security patch, which fixes 36 security issues. The size of this update is 2GB+.
Users can download the update by going to Settings> Software update> Download and install. The company is expected to roll out this update for the Galaxy A15 5G in other regions in the coming weeks.
One UI 8.5: Changelog
The update brings a redesigned user interface and additional features, including a transparent blur effect and support for Apple AirDrop. One UI 8.5 updates Photo Assist with continuous editing and AI-generated image creation, which requires a network connection and Samsung Account login. Output may include a visible watermark, and results can vary depending on device and UI.
Quick Share improvements allow the system to recognise people in photos and suggest sharing. Device connectivity features include Audio Broadcast for sending media and voice to nearby LE Audio devices using Auracast. This is limited to Galaxy S25 series models. Storage Share shows files from other Galaxy devices — phones, tablets (One UI 7+, kernel 5.15+), Galaxy Book2/Book4 models, and Samsung TVs released after 2025 (U8000 and above) — once all devices are signed into the same Samsung account with Bluetooth and Wi-Fi turned on. Availability differs by region and device.
Security additions include Theft Protection, Failed Authentication Lock for repeated unsuccessful unlock attempts, and broader identity checks for sensitive settings.
