Detecting some mobile devices

Question

What is a mobile device?

Are tablets considered to be mobile devices?

I want to detect some mobiles devices -- those that fall in the small screen range like iPhone, Android phones, iPod, etc. I do not want to check for tablets, like iPad, Kindle, etc.

My website has a mobile version that is designed to work on mobile devices like iPhone, etc.

I got this Coldfusion code from http://detectmobilebrowsers.com/. However, I believe it checks for all mobile devices. Most of the devices I am not aware of.

Can someone help me with this code, to check for small screen mobile devices only?

    <!--- Javascript to switch Div's for Mobile --->
    <cfset MobileFound = true>
</cfif>

In addition to checking for the presence of a mobile device, I also check the screen width. But, due to the complexity of the website layout, I use jQuery to switch content between two DIVs for the mobile version.

This is the code I use for screen width:

<cfif MobileFound eq true>
    <meta 
        name="viewport" 
        content="width=device-width, initial-scale=1.0, maximum-scale=1.5, 
        user-scalable=yes" 
    />
    <link 
        href=".../wBCCmobile.css" 
        rel="stylesheet" 
        type="text/css" 
        media="only screen and (min-width:300px) and (max-width:480px)" 
    />
</cfif>

Answer 1

I contacted http://detectmobilebrowsers.com and they assured me that their code only detects [small] mobile devices and not tablets.

Answer 2

You have not mentioned which language you are using?

If you are using php so you can try with below code.

if( strstr($_SERVER['HTTP_USER_AGENT'],'Android') ||
strstr($_SERVER['HTTP_USER_AGENT'],'webOS') ||
strstr($_SERVER['HTTP_USER_AGENT'],'iPhone') ||
strstr($_SERVER['HTTP_USER_AGENT'],'iPad') ||
strstr($_SERVER['HTTP_USER_AGENT'],'iPod'))
{
?>
<link href="give your mobile style sheet link" rel="stylesheet" type="text/css" />
<?php
}
?>

I hope you will get a result.
