Question

I'm using ASP .NET MVC2 and jquery UI Autocomplete.

Sometimes application runs in Samsung Galaxy Tab.

In this case it is very difficult to select customer name from jquery UI autocomplete.

How to dedect Samsung Galaxy tabto render select element insted of autocomplete in this case ?

I tried

HttpContext.Current.Request.Browser.IsMobileDevice

but it returns false for tabloid.
