This is my Lumia 1520 facebook messenger chat screen
As you can see there is a annoying black bar at the bottom and at first I thought that maybe the app is not optimized for my device screen yet but after several updates the issue still there and saw my friend screen so i wonder is there something wrong with my device or just a bug of the app . I also have same this issue with others app but most of my app is perfectly display on my screen especially game . Help me figure this guys
