I have just bought my first Android device, the ATT Galaxy Note. I have had a succession of Blackberrys, and was very used to being able to delete prior emails with one click. In the note, unless I'm missing something, I have to select each email and then delete, AND THEN go to the Trash and totally repeat the process. I use my phone to read emails, but only keep and file them on my laptop. Is there a better way?
Go to your Inbox, and click on the bottom left icon beside the Home Button...that should open up a window. In that window you should have a Delete Button, click that and now, click on all the Emails that you want to delete.
On the Samsung Note 5, go to your mailbox, in the upper right corner, select "more," then select "edit." This will bring up a box that will allow you to "select emails" at the top. With this you are able to select multiple emails or all emails. Select the emails you want to delete or select all and then hit the delete button.
