When exactly does post-update "Automatic reboot" happen?

daniel4ka

Hello,

Enabling the opt-in "Automatic reboot" setting allows the updater to reboot the device after an update once it has been idle for a long time.

But I'd like to know: After an update, assuming this setting is enabled, when exactly would the automatic reboot happen?

Thank you

From the source code it looks to me like an automatic reboot can only happen when the following conditions are met:

It has been at least 5 minutes after an update, as defined by setMinimumLatency
The device is idle, as defined by setRequiresDeviceIdle: "This state is a loose definition provided by the system. In general, it means that the device is not currently being used interactively, and has not been in use for some time."

Assuming that's right, now the question is: How is the device idle state defined by the GrapheneOS system (on its various supported devices)?

I tried finding the answer by digging into Android Code Search, especially JobInfo.java, but I didn't get anywhere.
Insight into this would be much appreciated.
Thank you.

I wish they added an option to the define the idle time.
