Sorry for the delayed reply... I guess mine is also still failing to go into standby. The screen goes off due to the settings as attached pic, but 7 times out of 10 when I come back to the mod after an hour or two it still come up with the fire screen, not the return from standby. Interesting because I have three other DNA75's here, two of which I built myself with bare 75 boards and I have not observed this behaviour with them. It seems only the Vapedroid C1D2 does this, or I have not noticed it so far on the others.
