Multitasking and App Pair
The App Pair feature lets you launch two apps simultaneously in a split-screen mode, perfect for productivity or research. For example, you can watch a Mets game while typing notes or browsing news. Access this feature via the Edge Panel, add your App Pair, and save it for quick use from the Home screen.
Customizing Your Display and Home Screen
You can set up Always On Display to show the time, notifications, and other info without unlocking the phone. Customize your Clock Style, colors, or widgets for a personalized experience. Adjust screen sensitivity if you use add-on screen protectors, and explore full-screen mode for apps to maximize screen real estate.

Bixby can help with voice commands, calorie counting, and managing apps. Setting it up takes about 10–15 minutes, including training and customizing cards. Meanwhile, Samsung Pay registration lets you add credit/debit cards and verify transactions using Intelligent Scan or fingerprint.
