Depends on the user agent, unfortunately, and I don't know just how standardized they are -- it is disabled if the user agent says _both_ `Android` and `Mobile`.  I don't know if all Android tablets skip the "Mobile" language -- @koenpunt, you added the regex in https://github.com/harvesthq/chosen/commit/3e54b0d2636e4572449b4ec076616db66dfa4bc7, do you know?
