How Page Layouts Work in the Salesforce Mobile App

Use the enhanced page layout editor to customize the layout of an object’s record detail pages, configure actions, and adjust which fields and related lists appear in the Salesforce mobile app.
Available in: both Salesforce Classic and Lightning Experience
Available in: All editions except Database.com

In the Salesforce mobile app, page layouts drive these areas of the mobile experience.
Record Related Information and Detail Pages
When you view a record in the mobile app, you see the fields, Visualforce pages, and related lists that are based on the record type and the user’s profile. Related lists show up as single-line cards containing the name of the page or related list. Tapping the related list card displays its details.
Mobile Cards
You can add expanded lookups, components, canvas apps, and Visualforce pages to the Mobile Cards section of your page layout to have them show up as mobile cards in the mobile app. The elements you place in this section don’t show up on a record’s detail page in the full Salesforce site. They appear only on the record’s related information page in the mobile app.

In organizations that are created after Spring ’14, the Twitter component is added by default to the Mobile Cards section of page layouts for objects that support it.

Note

Actions
Actions in the Salesforce Mobile and Lightning Experience Actions section of a page layout appear in the action bar and action menu on the object’s record pages.

Here are the record detail page, related information page, and action menu for a sample account, Edge Communications:
