    1

    Increase display size and font size

    ~26s
    Open Settings, scroll to Accessibility, then tap Display Size and Text. Drag the Font Size slider toward Large or Largest, and drag the Display Size slider toward Larger. On Samsung phones the path is Settings, Accessibility, Visibility Enhancements, Font Size and Style. Bigger Font Size only enlarges words. Bigger Display Size enlarges buttons and icons too, which helps with fingertip tapping.

    Quick Tip

    Quick Tip: Turn on Bold Text on the same screen so words look thicker, not only larger.

    2

    Set up magnification with a triple-tap

    ~19s
    Open Settings, Accessibility, Magnification. Turn on Magnification Shortcut. Choose either Triple-Tap or Accessibility Button. Pick Magnify Full Screen for the simplest mode. After setup, triple-tap anywhere to zoom in, drag with two fingers to move around, and triple-tap again to zoom out. This works system-wide, including inside the camera, the web browser, and text messages.
    3

    Turn on high contrast text and color correction

    ~22s
    In Settings, Accessibility, look for Text and Display, then High Contrast Text. This adds an outline to letters so they stand out from backgrounds. Tap Color Correction to add filters that help with red-green or blue-yellow colorblindness, common alongside diabetic retinopathy. Tap Color Inversion to switch to a dark-mode style — many people with light sensitivity prefer light text on a dark background.
    4

    Try TalkBack for hands-free screen reading

    ~29s
    TalkBack is the Android screen reader. Turn it on in Settings, Accessibility, TalkBack, Use TalkBack. The phone reads aloud whatever is touched. Swipe right with one finger to move to the next item, double-tap to open, swipe down then right to reach the global menu. Run the TalkBack tutorial twice before relying on it daily. To turn TalkBack off quickly, press and hold both volume keys for three seconds.

    Warning

    Note: TalkBack changes how single taps work. Beginners should practice on the home screen before opening Mail or banking apps.

    5

    Install Lookout for label and scene description

    ~25s
    Lookout is a free Google app for low vision. Install it from the Play Store, give it camera permission, and pick a mode. Text Mode reads aloud any text the camera sees, useful for mail and prescription bottles. Currency Mode names the dollar amount of US paper bills. Scene Mode briefly describes what is in front of the camera, like a person standing or a chair on the left. Lookout works offline once installed.
    6

    Add an Accessibility Button to the navigation bar

    ~21s
    Most modern Android phones support an Accessibility Button. Open Settings, Accessibility, Accessibility Button, and turn it on. A small floating button appears that activates Magnification, TalkBack, or any other chosen feature with one tap. This avoids digging into Settings every time. The button can be dragged to any edge of the screen and shrunk if it gets in the way.

    Android phones from Google, Samsung, Motorola, and other brands all include strong vision accessibility settings. The exact names and locations of the settings differ slightly from brand to brand, but the core tools are the same. Google publishes the Android Accessibility Suite, which includes TalkBack (the screen reader), Select to Speak, Lookout, and Live Transcribe. Samsung adds a separate set of features under Settings, Accessibility, including a Color Inversion mode and a Vision Booster.

    For an older adult with macular degeneration, glaucoma, or diabetic retinopathy, the most useful Android features are large display and font, magnification gestures, high-contrast text, color correction for colorblindness, and TalkBack for moments when the screen cannot be seen at all. Google also offers Lookout, a free camera-based app that reads aloud labels, signs, and currency. Lookout works without the internet for most modes once it has been downloaded.

    Unlike older Android versions, the modern setup wizard asks about accessibility needs on the very first screen, so a senior setting up a new phone can turn on the features before they ever see a tiny default menu. If the phone has already been set up without these features, they can be enabled at any time from the main Settings menu under Accessibility, with no factory reset needed.

    The Be My Eyes and Aira apps also run on Android. Be My Eyes is free and connects to volunteers. Aira is a paid service with professional agents. Both let a low-vision user point the camera at something and have a sighted person describe what is there. Sources include the Google Accessibility Help Center at support.google.com/accessibility, Samsung Support at samsung.com/us/support, and the American Foundation for the Blind at afb.org.
