To mark in the Email App of Android, all the Mails as read
- Open as usual the pre-installed Email App on your Android.
- Then highlight the emails you want to mark as read. Unfortunately you can not select all the Mails at the same time. If you want to select multiple emails, tap on the small rectangle in front of the date (for example, "Yesterday (4)" (see image). Thus, all E marked-Mails in the mentioned period.
- When you have selected all the required emails, tap the bottom right icon with the envelope and the hook (see picture).
- Now you have marked all of the selected E-Mails as read.
