    Android 14 features and changes list

    The following table lists all documented features and behavior changes that might affect app developers. Use this list to find changes that affect you, and then use the corresponding link to read the documentation.

    Category Type Name
    Accessibility Change (all apps) Test your app with non-linear font scaling
    Because Android supports font scaling up to 200%, you should perform UI testing to ensure that your app can accommodate larger font sizes without impacting usability.
    Accessibility New features and APIs Non-linear font scaling to 200%
    Android supports font scaling up to 200%, providing low-vision users with additional accessibility options that align with Web Content Accessibility Guidelines (WCAG).
    Camera and media New features and APIs Ultra HDR for images
    Android 14 adds support for 10-bit High Dynamic Range (HDR) images that retain more of the information from the sensor when taking a photo, which enables vibrant colors and greater contrast.
    Camera and media New features and APIs Zoom, Focus, Postview, and more in camera extensions
    Android 14 upgrades and improves camera extensions, allowing apps to handle longer processing times, which enables improved images using compute-intensive algorithms like low-light photography on supported devices.
    Camera and media New features and APIs In-sensor zoom
    Implement request override controls to give users zoom control even before other camera controls are ready.
    Camera and media New features and APIs Lossless USB audio
    Android 14 gains support for lossless audio formats for audiophile-level experiences over USB wired headsets.
    Core functionality Change (all apps) Apps can kill only their own background processes
    When your app calls killBackgroundProcesses(), the API can kill only the background processes of your own app.
    Core functionality Change (all apps) Schedule exact alarms are denied by default
    The SCHEDULE_EXACT_ALARM permission is no longer being pre-granted to most newly-installed apps targeting Android 13 and higher—the permission is denied by default.

    The system may place context-registered broadcasts in a queue when these broadcasts are queued for delivery to an app that's in the cached state.
    Core functionality Change (all apps) MTU is set to 517 for the first GATT client requesting an MTU
    The Android Bluetooth stack more strictly adheres to Version 5.2 of the Bluetooth Core Specification and requests the BLE ATT MTU to 517 bytes when the first GATT client requests an MTU using the BluetoothGatt#requestMtu(int) API, and disregards all subsequent MTU requests on that ACL connection.
    Core functionality Change (all apps) New reason an app can be placed in the restricted standby bucket
    Android 14 introduces a new reason an app can be placed into the restricted standby bucket.
    Core functionality Change (all apps) System enforces cached-app resource usage
    Shortly after an app process enters a cached state, background work is disallowed, until a process component re-enters an active state of the lifecycle.
    Core functionality Change (all apps) mlock limited to 64 KB
    In Android 14 and higher, the platform reduces the maximum memory that can be locked using mlock() to 64 KB per process.
    Core functionality Change (apps targeting 14+) Foreground service types are required
    If your app targets Android 14 or higher, it must specify at least one foreground service type for each foreground service within your app.
