User Agent for Code Igniter not detecting mobile devices like Android or Blackberry

[reypm]

I’m using CI UA library but if I navigate trough a BB device or a Android, I get always “Safari” as result. This is my code:
$this->load->library('user_agent');
if ($this->agent->is_browser()) {
$device = $this->agent->browser();
} elseif ($this->agent->is_mobile()) {
$device = $this->agent->mobile();
} else {
$device = "";
}

I test the UA returned by my browser and get this:
Mozilla/5.0 (X11; Linux i686; rv:12.0) Gecko/20100101 Firefox/12.0
And from my BB get this:
Mozilla/5.0 (Blackberry U;Blackberry 9300;en) AppleWebKit/534.8+ (KHTML, like Gecko) Version/6.00.668 Mobile Safari/534.8+
But UA class still saying for BB that it's Safari when is not.

Your logic is wrong ... Just because you're accessing the page from a mobile device, it doesn't mean that you're not using a browser. It's natural that is_browser() returns TRUE and since you're using elseif, your application never gets to the is_mobile() check, which works fine by itself.
