This is a lightweight mobile detection based on the Mobile_Detect.php library, which can be obtained from the GitHub repository.

This module is intended to aid developers utilizing mobile-first and responsive design techniques who also have a need for slight changes for mobile and tablet users. An example would be showing (or hiding) a block or content pane to a particular device.

This module is not intended (and never will be enhanced) to provide theme switching or redirection; other modules already provide this functionality.


As noted, this module does not include the actual Mobile_Detect library. This should be downloaded or cloned from one of the links above and placed in

  • sites/all/libraries/Mobile_Detect

or somewhere the Libraries API (if present) can find it, eg

  • sites/default/libraries/Mobile_Detect
  • sites/

Once the module is installed and enabled, browse to the Status Report page (admin/reports/status) and confirm that the library is found. The PHP file should have a pathname that is similar to

  • sites/all/libraries/Mobile_Detect/Mobile_Detect.php

If you think everything is installed correctly, you may need to clear the Drupal caches (admin/config/development/performance).

For testing purposes, the demo.php and unit tests included with the library can be deployed, but these should not exist on a live production server.


The base module just provides a factory method for creating a singleton of the mobile detection class, for use in themes and other modules:

$detect = mobile_detect_get_object();
$is_mobile = $detect->isMobile();
$is_tablet = $detect->isTablet();

See the documentation for the Mobile_Detect library for more information.

The base module also provides two blocks and a permission that you can add to your site to output the results from the various tests the class provides.

ctools Support

A sub-module is included for integration with ctools. Once enabled, a "Mobile Detect: device type" will show up in the list of selection and access rules. When this is used, the list of device types is dynamically built from the rules present in the Mobile_Detect library, and you can use any combination of AND/OR/NOT logic that you need.

Note that the Mobile_Detect considers tablet devices as also being mobile devices. When you have both tablet and mobile device selection in use, it is best to place the tablet rules first. For example, when using with for Panel page selection rules, place the Table variant before the Mobile variant.

Drupal Page Cache Support

Experimental support is provided for working with the Drupal page cache. To
use this, enable the mobile_detect_caching module. And then add

$conf['cache_backends'][] = 'sites/all/modules/mobile_detect/mobile_detect_caching/';
$conf['cache_class_cache_page'] = 'MobileDetectCache';
$conf['mobile_detect_library'] = 'sites/all/libraries/Mobile_Detect/Mobile_Detect.php';

To your settings.php file. You may need to adjust the path if you installed the module in a different location.

Problems should be reported on

Problems, Bugs, Suggestions, Etc.

Problems with the actual Mobile_Detect library should be directed to the GitHub issue queue.

Problems with this module and sub-modules should be directed to the Drupal issue queue for this project.


A sub-module for creating Context conditions is also planned.

A sub-module for solving the cached page issue (see is underway.

Module and Theme Support

The following projects currently support Mobile Detect:


Similar modules:

This is an improved version of the PHP get_browser() command. Mobile_Detect has a smaller footprint, but Browscap can provide more information and is not mobile-centric.
Mobile Tools
This is a full-featured module aimed at developing full-featured mobile sites. As such it has a heavier footprint, but also provides more features, such as redirection and theme-swicthing.

Work initially sponsored by Night Kitchen Interactive.
