Samsung has updated these Galaxy devices to Android 15

Samsung’s massive Android 15 upgrade cycle—packaged inside the highly anticipated One UI 7 interface—has hit full stride. Following an extended development and testing phase that initially saw the software debut exclusively on the flagship Galaxy S25 lineup, Samsung has aggressively pushed the stable firmware over-the-air (OTA) to generations of older flagships, mid-rangers, and tablets.

The update introduces a complete visual overhaul, featuring a heavily reconstructed, split Quick Panel layout, the new lock screen “Now Bar” for live event tracking, and advanced on-device Galaxy AI privacy controls.

If you’re wondering whether your specific device has received the upgrade notification, here is the official rollout matrix of Samsung Galaxy hardware actively running stable Android 15.
