My old Nokia Lumia Smartphone had played Systemsounds when locking/unlocking it. (Waterdrop like sound when unlocking and a doorlock sound when locked)
In some Situations this is very helpful to know, specially when unlocking it in the bag while hearing music over Bluetooth and you know that your phone is accidentially unlocked and random screen presses can occur.
So my dear Withsailors the big question here for me is:
Where to configurire it?
And when its not supported maybe this is a fearure-request worth?
