phonegap: adapt the width to 100%

This is not really a project devlopement, but I am looking for someone who can help me solve a phonegap problem. My page (1 single html page) looks great on my Samsung S4 phone (it takes 100% of viewport). But once compiled to phonegap (phonegap builde adobe service), viewport is not scaled to 960px any more and big scrolls appear. Here is this simpel page. - If you open it on your device or on your chrome mobile simulator, portview is 100% and everything is perfect. - if you compile it with phonegap, big horizontal scrolls appear since viewport is not scaled. Here is the link to the question I have posted: [login to view URL]
