Proxy settings on Mobile is not always straightforward, it depends on the distribution, the stock ROMs often have their proxy page orphaned so you cannot get to it, unless you install something like "Proxy Settings", that provide a way to get to that page.
On most custom ROMs you can set your proxy settings, but that doesnt mean all apps use it.

You can set the proxy, and that proxy is being used by the installed Dolphin browser ( make sure you stop/start the app to pick up the changes in these settings).
But this Dolphin does not properly use HTTP headers causing this when using https:
[client 10.0.0.138] client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /
I ended up installing Firefox for Android, which offers setting the proxy settings in Firefox itself.
You can make these settings via the about:config URL, the following options should be set :
mod_pagespeed#

Google's speed up module for Apache httpd (and nginx).

Now you think, hey, an open proxy, SPAMMERS !
Well, I can't reveal all details here, but I took some measures to make sure I can only use the proxy myself :-)
