need multi window feature in oneplus 2 in marshmallow
You won't get this feature built-in. You can download 3rd party apps from Google Play Store for multi window. You can try them.
Nope you don't need it. You just want it.
What if he's trying to complete his life's research?
that's so 2016 bruh!
if you have your bootloader unlocked, you could try this , android 6 has multiwindow build in it, but it is not the final version (i have not tried this method, but it should work)
3rd party apps don't give you a complete and useful experience of multiwindow. You have to flash a custom rom with nougat, in my opinion.
