Mobile Site

Hi there team,

After creating my site on your theme im checking constantly in mobile to see how it goes de desing of it. Amd after a while i realise that the web dont recognise my mobile device (samsung J5) because is all the same.

If i put on the Slider revolution. Dont show it on mobile device is still the same.

If change the background for mobile it keep the same.

So how should i activate for the mobile site while browsing trough a mobile device?
