TL;DR
  • Early One UI 9.5 test builds reveal upcoming changes to Samsung Calendar and Samsung Health.
  • Samsung Calendar is getting a cleaner, grid-free interface, a relocated search button, and a new Key events section.
  • Samsung Health is gaining Mindful note, a new journaling feature with guided prompts and daily reminders.

Samsung’s One UI 9 rollout is still underway, but that isn’t stopping the South Korean tech giant from preparing its next big software update. With One UI 9.5 currently in development, and an early beta build for the Galaxy S26 Ultra already spotted on a test server, we’re starting to inch closer to Samsung’s second Android 17-based update.

Samsung hasn’t detailed what’s coming with the update, but that hasn’t stopped testers from getting their hands on the unreleased software and uncovering the changes.
