The count on the Gmail icon represents the number of unread emails present in the Gmail account. This count shows exactly the number of emails that will not open by the user, and this count increased.  The count may vary if the user opens the account and reads the emails. This count contains all the emails, including all categories of emails, even promotion emails, and spam emails. The number of emails that are unread changes when the device will connect to the internet and uses low data to update.  This will update automatically when the Gmail application has permission to access the internet, regardless of permission. It consumes data at a few kilobits, which is negligible. Users cannot uninstall the Gmail application because it comes with the inbuilt operating system as a default.
