Phone Icon not displayed footer page in the Sugar CRM Version 10.2

In our SugarCRM demobuilder instance we are able to create the Sugar Instance using the version 10.2 . Also we are able to upload and install the Integration zip file in the Module Loader.
But the Newly added button is not displayed in the footer page of the newly created SugarCRM Instance.
We found in the HTML, a newly added button present inside the  <div id="button"> </div> block, but outside of the <footer></footer> tag. 
also Sugar Exchange button also outside of <footer></footer> tag.
Hence the Phone Icon is not displayed. Using the same Module Package we are able to see the Phone Icon using the SugarCRM Version 9.0.
Please share the steps to add customized button in the footer page in sugar CRM Version 10.x
$viewdefs['base']['layout']['footer']['components'][] = array (
'view' => 'layout-view,
);
Please let us know any view definition change in Sugar CRM Version 10.x
