    • The LGE (FOTA) solution is now able to pause AB Streaming of an OS update if a device switches to a network type that is not preferred by the administrator (i.e. cellular or other metered network), and resume when the device returns to the preferred network type (i.e. Wi-Fi).

IMPORTANT: The AB Streaming Pause/Resume feature is supported only on WAN-enabled devices running Android 11 or later with LifeGuard Update 11-16-05.00-RG-U27

    • Device user is now able to select whether to use a metered/cellular network for Zebra Auto Updates via device UI available in FOTA Settings.
