If you have access to the SharePoint file system on your front-end servers, you can disable the mobile
view for all sites in a specific web application’s zone by adding the following in the zone’s web.config
file, inside the <system.web> section:
<browserCaps>
<result type=”System.Web.Mobile.MobileCapabilities, System.Web.Mobile, Version=4.0.0
.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a” />
<filter>isMobileDevice=false</filter>
</browserCaps>
