Good morning, everyone.
To make my site known, sharing with social networks works, but with email, it doesn't work ( while "mailto" works on PC).
When I click on the email icon, it is impossible to open the mobile's email ( it opens a blank page) .
Is it possible to do that?
Thank you in advance for your answer.

Well, mailto is standard so problem is with program you use

Hello.
If I understand, since not all mobile users have the same mail program, there is a configuration problem.
I'll try to find out about an Android forum, maybe someone will have a tip.
Thank you for your answer anyway.

It's not related to mailing program, it's html standard:

Hello MB Themes.
I'm going to give up the idea of sharing by e-mail on mobile. The important thing is to share with social networks.
Thanks again for the help.
