Actually, the native Mail app on Android can vary by device (Samsung, Pixel, etc.), but most Android users use the Gmail app for email. However, if you want to add your Gmail account to a different native email app (like Samsung Email or a third-party app), here’s a general guide:
Open the Mail app you want to use (e.g., Samsung Email).
Tap Add Account or go to Settings > Accounts > Add Account.
Select Google if it's listed.
If it's not, choose IMAP or Email.
Enter your Gmail address and tap Next.
Enter your password and complete 2-Step Verification if prompted.
Grant the necessary permissions.
Adjust sync settings and tap Done.
