Samsung’s One UI 8.5 beta program is expanding its reach. Initially set for six countries, the program was only accessible in four during its first phase. The second phase has now commenced, allowing users in India and Poland to join the beta testing. The update, available for the Galaxy S25 series, carries a firmware version ending in ZYLH and is over 4GB in size, including the December 2025 security patch. This same firmware will soon be released as a second beta update in Germany, South Korea, the UK, and the USA. One UI 8.5, built on Android 16, introduces numerous enhancements such as lock screen clock customization, a new design language for stock apps, improved AI-powered image editing, and several other features aimed at boosting performance and reliability.
