When I press the Multi window icon on the notifications bar it stays grey, doesn't turn green. It's a brand new phone (At&t) and I upgraded the OS to kit kat. Can someone help me figuring this issue out?
Thank you
You can also long press the toggle button in the notification bar to bring up the Display menu. In there, there is a Multi window check box. Make sure it is checked. If you don't like the shortcut, you can also get here by going Settings>My device tab>Display
