I recently developed a web site for a marketing campaign and I decided to use SharePoint Foundation 2010 as the platform. The web site looked great when viewed from the browser, however, I was getting a lot of complaints that the web site wasn’t viewable from people’s BlackBerrys and iPhones.
On mobile phones, SharePoint seems to redirect to the View All Site Content page (/_layouts/mobile/mbllists.aspx). The screen that showed on my own iPhone looked something like this:
My Web Site
Site Collection Images
-Sites and Workspaces
Home(My Web Site)
This isn’t very helpful for the average user who just wants to get to the home page directly. Furthermore, I really don’t want users seeing my list and library structure and I definitely didn’t want users to have to browse down to the web page itself where ever it may be (in my case the Site Assets document library).
I really didn’t have any time to create a mobile view for the web site and I figured that most mobile phones now a days have screens good enough to view most full size web sites.
At first, I thought disabling mobile views might be a site setting so I went to my Site Actions –> Site Settings pages to see where this might be. First thing I noticed was the Mobile Site URL (?Mobile=1) on my site settings home page:
Next, I started digging around the Central Administration Site Settings and my Web Site Site Settings for this setting but it was no where to be found. And then I went digging through the API to see if this was a flag to turn this off and nothing.
In the end I found this blog post by the Office Team  which helped me realize what I was missing. SharePoint is just using the default ASP.NET Browser Definition File Schema  to control whether it’s control adapters will redirect to the mobile views of SharePoint or not.
There is an App_Browsers directory by default in a SharePoint created web application structure (i.e. C:\inetpub\wwwroot\wss\VirtualDirectories\80) which is called compat.browser.
Opening this file up, you see the various browsers and a flag called isMobileDevice:
To disable mobile SharePoint views, just find the browsers you want to disable it for and set the value of this flag to “false”. Or do what I did and do a find and replace on:
<capability name="isMobileDevice" value="true" />
<capability name="isMobileDevice" value="false" />
Just watch out for extra spacing during your find and replace.
