I am using a Moko case with magnetic front cover. When I close the cover, it turns the screen off and locks the device. When I open the cover, it turns the screen on and shows me the lock screen. However, it seems like sometimes when the cover has been closed for a very long period of time, then when I open the cover, the screen doesn't turn on, and I have to press the power button to get to the lock screen.
Is this expected behavior when the device enters some sort of deeper sleep state after a long time of inactivity? Or is it a bug?
