    Restore pop-ups snapped to the edge of the screen

    Check minimized apps with the S Pen
    Hover your S Pen above a floating app icon to see a preview of how the app will appear when you open it.

    Taskbar

    More recent apps
    You can now choose how many recently used apps to show on the taskbar (up to 4).

    Easier navigation
    When fewer than 8 icons are shown on the taskbar, the navigation area will automatically resize to give you more space for the navigation buttons.

    Flex mode

    Use the Flex mode panel with more apps
    More apps can now be used with the Flex mode panel. When the Flex mode panel is turned on, just fold your phone upright and tap the button that appears on the navigation bar.

    Buttons for skipping forward and backward 10 seconds are now available on the Flex mode panel. When you touch the time bar, the time you'll move to will be shown to help you find the right moment.

    Customize the toolbar
    Create your own personal layout to quickly access features like split screen view, screen capture, and more. Touch and hold an icon on the Flex mode panel toolbar to reorder the icons or move icons into or out of the toolbar.

    Quick Share

    Share with contacts
    You can now send files to your contacts anytime, even if they're not near you.

    Protect private content when you share it. You can set expiration dates for the files you send, cancel sharing at any time, and prevent recipients from saving or resharing.

    Select multiple pictures in Capture view
    While using Capture view on the main screen, you can now press and hold to select multiple pictures. After selecting, you can share or delete them all at once.

    Enhanced remaster previews
    Thumbnail images are now shown below the image you're remastering. Tap a thumbnail to compare the remastered image to the original with a larger view.

    Apply effects more easily
    Filter and tone effects in Gallery now use a dial instead of a slider making it easier to make precise adjustments with just one hand.

    Copy and paste effects
    You can now copy and paste filters and tones from one picture you’ve edited to another.

    Additional changes

    Drag and drop with two hands
    Start dragging files, app icons, or other items with one hand, then use your other hand to navigate to the folder or location where you want to drop them. Supported in My Files and the Home screen.

    Continue using your phone while charging another device
    Open your phone with the main screen facing down. You can charge your Galaxy Buds, Galaxy Watch, or another device using wireless power sharing on one side. At the same time, you can continue using your phone with the cover screen on the other side.

    Keep storage space available
    When you’re running low on space in your internal storage, app cache information will be shown when you analyze storage in My Files. Clearing app caches can help you free up space without deleting files or apps.

    Enhanced memory management in Device care
    More information is provided about apps using memory on your phone, giving you the option to put apps to sleep if too much memory is being used.

    Change your mode from the Lock screen
    Change between Sleep mode, Driving mode, and other modes directly from the Lock screen.

    Customize your layout in Samsung Internet
    When you choose to show the address bar at the bottom of the screen, the tab bar and bookmark bar will also be shown at the bottom.

    How to flash F926BXXU5FWI2

    • F926BXXU5FWI2 has bootloader binary 5. Your device must run binary 5 or lower: it is the 5th character from the end of your current build number.
    • CSC: Use CSC for a clean install, to change the region (CSC code), to downgrade or to repair a device that does not boot.
    • HOME_CSC: Use HOME_CSC to update the same model and region while keeping your data. Back up anyway: a failed update can still require a reset.
    • The Download Mode key combo depends on the model: see all combos.
