I have a question about Huawei Mate 8 dual window option!

[Hamza Jahic]

So I know that fresh out the box Huawei Mate 8 doesn't support apps like Facebook, Twitter, Viber, Youtube etc in it's ''Dual Window'' mode, is there any update or way to make these apps work with dual window option.I heard that there are firmware updates but can I get them trough system settings update or doing some manual work.
