[Plugin: WP Bannerize] PHP Fatal error

me too, only wiht default browser of android 4.1 and dolphin hd

The error log is giving
PHP Fatal error: Call to a member function bannerize() on a non-object in /home/projseg/public_html/blog/wp-content/plugins/wp-bannerize/Classes/wpBannerizeWidget.php on line 64, referer: https://blog/wp-admin/customize.php
I am using version 3.0.62 with WordPress 3.5.1

me too. In default browser of Android 4.2.2.

A temporal fix is add a change in the line 64 of wp-bannerize/Classes/wpBannerizeWidget.php

function widget( $args, $instance ) {
    global $wpBannerizeFrontend;
    $new_args = array_merge( $args, $instance );
    if (isset($wpBannerizeFrontend)) // add this line
        echo $wpBannerizeFrontend->bannerize( $new_args );
}
