Plugin to load theme if mobile and specific page

Question

I've been browsing some of the other questions and I haven't been able to find a solution. There was a great solution to part of my problem that I'm basing this code on. I need to detect if on mobile, and display the mobile theme with one exception. If a user is on mobile and on page ID 145 the normal theme needs to be used. This is the code I have that works, except does not display the normal theme on that specific page on mobile. I've tried some variations with no luck. Thanks for looking.

add_filter('template', 'change_theme');
add_filter('option_template', 'change_theme');
add_filter('option_stylesheet', 'change_theme');
function change_theme($theme) {
    if ( wp_is_mobile() ) {
        $theme = 'SelectThemeMobile';

    } 

    elseif ( is_page( 145 ) && wp_is_mobile() ) {

        $theme = 'SelectThemeOne';
    }

    return $theme;
}

Try:

add_filter('template', 'change_theme');
add_filter('option_template', 'change_theme');
add_filter('option_stylesheet', 'change_theme');
function change_theme($theme) {
    if ( wp_is_mobile() ) {
        $theme = 'SelectThemeMobile';

    } 

    $page = get_page_by_title( 'Title for 145' )

    if ( is_page($page->ID) and wp_is_mobile())
        $theme = 'SelectThemeOne';
        // Replace name below with hook for missing stylesheet
        wp_enqueue_style( 'registered name of missing mobile stylesheet');

    }

    return $theme;
}

I believe you must iterate the entire array of Pages in order to evaluate is_page().
