Query regarding responsive website design

[LiamGamerr]

Hello.

I am currently working on a responsive website design(newbie)
Is there a reason why during inspection of responsive websites in google chrome, the iphone 6/7/8 and the Pixel 2 phones show the desktop version of the site but the other phones/iphones show the mobile version?

You might have enable "Show desktop version" in your mobile browser' options. Or your detection script fails on these two phones.
