Sometimes we have to hide some content on mobile devices, because we want to improve user experience for mobile users. In SEO, there is the concept of cloaking, where you show the search engine a piece of content that is not what the user sees.  In this case, we have in our mind the question: Is hidden content fine for Google? 

 Google’s official definition seems a bit fuzzy / general:

Cloaking refers to the practice of presenting different content or URLs to users and search engines. Serving up different results based on user agent may cause your site to be perceived as deceptive and removed from the Google index.

and:

If the file that Googlebot sees is not identical to the file that a typical user sees, then you’re in a high-risk category…

Can Google punish our website for hidden content on a mobile ?

No.
