Hi,

I got this with :

Code:

...
'user_agent : '.$this->input->user_agent(),
'platform : '.$this->agent->platform(),
'browser : '.$this->agent->browser(),
'version : '.$this->agent->version(),
...

give 

Code:

user_agent : Mozilla/5.0 (Linux; Android 8.0.0; ONEPLUS A3003 Build/OPR6.170623.013) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.84 Mobile Safari/537.36
platform : Android
browser : Opera
