Along with the 
AdWords UI and 
API, AdWords scripts will be rolling out support for desktop and tablet bid modifiers (in addition to mobile) to accounts over the coming weeks. This functionality will be available for ad groups in the new 
AdGroupDevices class. For campaigns, you will be able to use the new 
tablet() and 
desktop() methods in the 
PlatformSelector class. See our code examples for 
ad groups and 
campaigns to learn more about using these methods.
Note: During the rollout, if the feature is not yet enabled in your account, attempts to set tablet and desktop bid modifiers will fail.
With this launch, the 
getMobileBidModifier() and 
setMobileBidModifier() methods of the 
AdGroup and 
ShoppingAdGroup classes will be deprecated. Updating existing scripts to use the new ad group interface is straightforward. For example, 
adGroup.getMobileBidModifier() becomes 
adGroup.devices().getMobileBidModifier().
If you have any questions about these changes or AdWords scripts in general, you can post them on our
 developer forum.
