Key changes with Android version 9.0

The Samsung One UI, Android version 9.0 operating system, has been updated with an intuitive and accessible design, making it easier to do everything with one hand.

Find out more about some of the main changes below. 

Please note: Android version 9.0 is only available to download on certain models, and this may differ based on region. This software comes as default on the Galaxy S10’s.

Updated designClick to Expand

You will notice that the Home screen, phone app, calendar, messages, email, notification panel and more have all been redesigned for a better user experience. There’s a more user-friendly and simplified design for many of the icons and menus.

Always on Display


The default clock on the Always on Display (AOD) is now positioned horizontally and features coloured icons. It shows remaining battery time, time remaining until fully charged, and also battery information for any other connected devices like wearables. It can also be fully customised by using different layouts or by uploading images or GIFs.


Video player


The control buttons on the video player have moved. They are now at the bottom of the screen, making them easier to interact with.
