I use this code to hide blocks in mobile view and it works perfectly. past this code in your page.tpl.php file and add ID hidden to the block or in my case adsenese Ad unit.
`
jQuery(document).ready(function($){
if( /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent)) { $("#hide").css("display", "none"); } }); `
