Hello! What font does Xiaomi use in the gmail app?

Roboto  Suggeriti da QuestionMarks 
Product Sans  Suggeriti da QuestionMarks 

There are 2 typefaces in the picture:
1. Product Sans. It's a contemporary geometric sans made by Google for branding purposes. As far as I'm concerned, you unfortunately cannot download or use it.
2. Roboto. It's a neo-grotesque sans-serif typeface developed by Google, and is available for download on the Google Fonts website.

And I am sorry for my terrible English skills. English is not my native language.

Thank you so much!
