Hi,
By default SharePoint 2013 detects if the site is being displayed in a mobile device and shows the content in a very simplified portal that remove most of the features.
There are few ways to can deactivate the mobile browser feature.
Deactivate SharePoint Mobile feature:
Open your site and go to Site Settings -> Manage site features
Locate Mobile Browser View and click Deactivate
Turn Off Mobile Browsing in SharePoint 2010
Navigate to your site root under wss/VirtualDirectories and then your site port number then open the folder called App_Browsers and open compat.browser file using Notepad.
\\YourSP2010ServerName\c$\inetpub\wwwroot\wss\VirtualDirectories\80\App_Browsers\compat.browser
For Example : Look for iPhone Safari Browser comment or any other mobile devices you see fit and change the value from true to false. Especially for iPhone Safari Browser, iPod Safari Browser and Android Safari Browser.
<capability name="isMobileDevice" value="true" />
Change to:
<capability name="isMobileDevice" value="false" />
Hope this helps :)
