@x_tof It's from the Android 16 QPR1 UI overhaul. It majorly improved quick tiles and you can now have 4 per row instead of 1 along with more functionality being added to certain ones like Bluetooth when they're expanded to being 2 wide. You can use the reset button at the bottom of the quick tile edit menu shown with the edit button in the notification tray to switch to the new default layout which has much more compact/dense functionality while still having the same information as before.
