All of a sudden, my Z10 has decided to allow my screen to darken and then blackout DURING map navigation.
So, of course, the maps app itself times-out and the turn-by-turn navigation stops working, once my screen turns black.
Up until a few days ago, my map app would always stay on-screen during turn-by-turn navigation.
What has happened and how do I fix this? It makes turn-by-turn navigation useless.
Thanks.
