Z5 and Z5 dual

[Last-man]

Hi I have some questions about Z5 dual. First : will the Z5 dual update to android marshmallow 6.0 just like as Z5?
Another question is this : does the both of sim slots support 4G?
And last question:is there any difference between Z5 and Z5 dual such as charge/decharge time or display or performance?

Exact same phone, but the Dual version can carry two SIM cards rather than just one.
