after reading @gzost's response.. I started tinkering.. since nothing else can properly detect WS's on my android phone... even websocket.org says i have it, but then fails to connect.

Anyways, try this workaround.. seems to properly detect it on/off with chrome, FF, safari and the default android browser.

var has_ws=0;
function checkWebSocket(){
  try{
    websocket = new WebSocket("ws:websocket.org");
    websocket.close('');
  }catch(e){ //throws code 15 if has socket to me babies
    has_ws=1;
  }
}

$(document).ready(function(){
  checkWebSocket();
});
