How to see Console log output in samsung galaxy S2

Warning: No Longer Working!

This solution appears to no longer be functional as the web tool has not been maintained over the years.

Try using JSConsole.com. It's a remote debugger for JavaScript. The setup is basically just injecting a <script> tag in your page. Once connected you can read all the console.log calls from the remote page on JSConsole, as well as execute commands on the client.

Steps to Setup

1. Go to JSConsole Home Page, and type :listen.
2. Copy the resulting <script src="http://jsconsole.com/remote.js?..."></script>.
3. Drop that into the page you need to debug.
4. Open your page in any browser (phone, tablet, desktop, etc). All console.log calls will be forwarded to the JSConsole.com window.

There are more details plus a couple of useful videos on the Remote Debugging Page.
