Detect if HTC "Fast boot" is enabled

Question

Some HTC phones have a feature called Fast boot (can be enabled under Preferences -> Power). As I have understood it this works like hibernation.

When started again no BOOT_COMPLETEDetc. will be sent, instead applications will be 'resumed'. This is very hard for me to handle in my application (auto-start, depends on SD-card etc).

I think the best I could do right now is inform the user to disable Fast boot for the best experience.

As this is a non-standard setting how can I detect if it is enabled?

Answer 1

I would suggest looking into the ACTION_USER_PRESENT broadcast which is typically sent when the user unlocks the phone. From what I was able to find about the HTC fast-boot (terrible name, as it conflicts in search results with the regular fastboot), it is just putting the phone in sleep mode and wakes up to a lock screen.

Another alternative to explore is ACTION_SCREEN_ON
