This note 8 is new to me, so it has recently been factory reset. Unfortunately in settings the Multi Window is greyed out, so I can't even select it. Im on Cricket with Android 7.1.1.
Not using Easy Mode.
Any suggestions?
I am having this exact problem with my Note 8. I'm running Android 7.1.1 and the Multi Window setting is greyed-out. I have recently (a week ago) factory reset this phone that is new to me, but am not sure how to activate the Multi Window feature.
