To avoid disrupting users, it is recommended that updates are scheduled when the device is in idle maintenance mode, such as overnight, and on Wi-Fi.
However, your client can use any heuristics you want. Check in with your OTA package servers and determine whether an update is available. Google's client also includes a Check now button for users to check for the latest update. The bootloader will fallback to the old OS if the new OS fails to boot, so no work is required from the client.
If the update fails, the client needs to decide when and whether to try again, based on the detailed error code. For example, a good client could recognize that a partial "diff" OTA package fails and try a full OTA package instead.
Optionally, the client can: Show a notification asking the user to reboot. If you want to implement a policy where the user is encouraged to routinely update, then this notification can be added to your client.
