Not sure this is a LL issue/change but since I am using LL and LL lockscreen, this seems the best place to ask. I have recently done the Android 5.0 update, and LL works fine. But I have noticed a major change in behaviour (not sur if LL or Google). Before 5.0 when locking phone while on an app, I would get back to the app when unlocking. With 5.0 as I unlock the phone I am systematically back to desktop. 

Is there a way to prevent this from happening and get back to the previous behaviour.
