Access all contacts at once on device?

I doubt this is possible but is there a way to get a list of all the contacts on both Android and iOS without having to select each one? I am wanting to export them but with the user’s permission.

Thanks

Isn’t there the “Select all” Button when you open the contact selecting option?
