when I post from my mobile ,its coming up as  "Posted From Android 2.0"

Should it not be  "Posted From Sony Z5 Compact" ?

Is your Sony Z5 Compact running 2.0? I thought it was on 4.0 or 5.0? 

That little tagline under the posts that came from mobile isn't an exact science, sometimes a custom ROM, updated firmware or older devices just aren't detected correctly but it is handy for us to see at a glance if someone is on mobile or desktop while posting.

It's a feature I can turn off though, if it gets too unruly

Its on Nougat so its 7.0, maybe as its a new ROM its not being picked up right as of now

Very possibly, I actually don't think I've seen any of the taglines coming up as "Posted From Android 7.0" yet, so it could be that it hasn't been worked out yet.
