System Update Policy

Control when system updates (including security and operating system updates) are applied to devices. (Supported on devices running Android 9.0 or later.) You do this when:

Note: This profile configuration is the equivalent of the set_system_update_policy script command.

Installation Policy

Choose an installation policy that


Automatic	Allows system updates to proceed on the device as soon as they are available.
Windowed	Restricts the installation of system updates to the specified time period. Set the Starting and Ending times of the window.
Postponed	Delays the installation of system updates for 30 days, after which the device user is prompted to install the update. Note: The 30 day timer will reset if a new update becomes available while a previous update is being postponed.

Annual OTA Update Freeze Periods

Under Update Schedule, select the Add button to display a table where you can create an annual window during which system updates are not applied to the device regardless of what is set in the Installation Policy section.

Choose a start date and an end date with the calendar pickers. You can add multiple freeze periods. Freeze periods cannot exceed 90 days or overlap. Additionally, they must be separated by at least 60 days from another freeze period. That is, if you set a freeze period of January 01 to January 31, the next earliest freeze period that you can set is April 02.
