Blogger defaults mobile users (excluding tablet users) to a mobile-friendly version of your blog.
To verify how the blog renders on mobile devices, access the mobile template section of your Blogger dashboard and follow these instructions.
Customizations are possible by selecting the Custom mobile template (Template > Choose mobile template) which adapts the original template customizations to mobile.
