    You can now search your Gallery for more than one person or subject at the same time. You can even search for people without tagging their names just by tapping their faces.

    Create a shared family album
    It's easier than ever to share pictures with your family. Gallery will recommend pictures to add to your shared family album by recognizing the faces of family members you select. You get 5 GB of storage for each family member (up to 6 people).

    Revamped info display
    When you swipe up while viewing a picture or video in your Gallery, you can see when and where the picture was taken, which device took the picture, where the picture is stored, and more. Now with a simpler layout.

    Multitasking

    Easily minimize or switch to full screen
    You can now minimize or maximize an app window without going to the options menu. Just drag one of the corners.

    Access your most used apps in split screen
    When you start a split-screen view, the apps you use most often will be shown below your recently used apps to help you find the apps you need faster.

    Modes and Routines

    Change wallpapers based on your mode
    Set a different wallpaper based on your current activity. Choose one wallpaper for work, one for exercising, and more.

    More actions for routines
    New actions let you control Quick Share and Touch sensitivity, change your ringtone, and change your font style.

    Weather

    Quick access to useful information
    Check severe weather alerts, daily weather summaries, and sunrise/sunset times at the top of the Weather app. The temperature graph now uses colors to show how the temperature changes throughout the day.

    Hourly precipitation graph
    An hourly graph now shows how much precipitation has fallen at different times of the day.

    Summary on Weather widget
    A brief summary of the current weather conditions now appears on the weather widget to let you know if it's sunny, cloudy, raining, or snowing.

    Samsung Internet

    Continue browsing on another device
    If you're browsing the web on one Galaxy phone or tablet and later open the Internet app on another Galaxy device signed in to the same Samsung account, a button will appear that lets you open the last webpage you were viewing on the other device.

    Improved search
    Your searches now include the names of bookmark folders and tab groups. Improved search logic lets you find what you're looking for even if something isn't spelled correctly.

    Additional changes

    Check the battery level of your devices
    The new Battery widget lets you check the battery level of your devices, right from the Home screen. You can see how much battery is left on your phone, Galaxy Buds, Galaxy Watch, and other supported devices.

    How to flash A236BXXU3CWC1

    • A236BXXU3CWC1 has bootloader binary 3. Your device must run binary 3 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.
