Hi all, today I updated my Z3's OS to 10.3. After updating, my BBM showing friends name in active chat in white colour that's why i'm unable to viewing their name and activity of "writing message"
Open the blackberry messenger app, (not from hub) and pull down from the top. There should be help, barcode, and settings. In settings there are some options to reset background etc, which might set it to black writing on white, or go with dark mode (my preference) which is white on black/grey. Hope that's what you were looking for!
