Hi,

I used SD over the weekend quite extensively and encountered, that it activated my iPad's screensaver/lock after a while of inactivity.
This never happened before the iOS update. I cannot exactly say how long it took to darken my screen - but it definitely is problem, as I need to swipe to unlock, enter my PIN, ... just to have a look at the map again.

If there is a setting I screwed up or I just need to change, let me know - but I fear, it is another iOS 8(.0.2)-induced problem. 

Cheers,
Markus

In my case, there was no smart Cover involved. Since I never had one, the setting to disable it doesn't appear either.
But there is a setting controlling the screen lock after inactivity, it was set to two minutes in my device. I can switch it off entirely. But I thought SD would do so during flight mode... In general I'd like to leave the automatical screen lock turned on and have only special apps keep everything up.

I have never had my device sleep in flight - SD definitely keeps it awake regardless of the timeout settings.

All I can think is that either...

1) SD crashed - was it still running when you went back to it?
2) Someone accidentally bumped the home or power button
