The previous XDK version was working well, now I downloaded the new version (3088) all is working fine but not the "TEST" mode with my Samsung S4 with a Cocos2d JS (Full) project created now from scratch from XDK templates.
Both "mobile" and "wifi" has the same result (black screen).
If I go in "debug" using the cable it works, If I build the apk and install it on the phone it works.
Interesting is that If I create a new project starting from "Cosos2d Lite" (instead of Full) it works fine also in TEST mode!
So it seems a mix of the Cocos2D Full library project and the TEST feature of XDK.
