Hi Suman,
have you tried accessing the same ITSMobile service on a Chrome Browser usign the Developer Tools (CTRL + Shift + L)and using the toggle device mode (CTRL + Shift + M) and inputing the screen size in pixels. Does the ITSMobile service display like in the "1.jpg"?
The ITSMobile Visual Editor might be useful here: https://wiki.scn.sap.com/wiki/x/-QRPF
