Once you’ve downloaded the Gmail attachment to your phone, it should be in your Downloads folder (or whatever you set as the default download folder on your phone). You can access this using the default file manager app on your phone (called ‘Files’ on stock Android), then navigating to the Download folder within that.
Where do email attachments get saved on Android?
Attachments are saved on either the phone’s internal storage or removable storage (the microSD card). You can view that folder by using the Downloads app. If that app isn’t available, look for a My Files app, or you can obtain a file management app from the Google Play Store.
Where do my Gmail attachments go?
By default, all of your attachments will be saved in your Documents folder but you can choose a different location each time you save attachments. You can also save an attachment by dragging and dropping the attachment from your email message to your desktop.
