You can mark your emails as unread in Gmail for Android phones and tablets (Samsung Galaxy, HTC,...). To mark as unread in Gmail for Android do as follows:
1. Open "Gmail" App
2. Open the Email to be marked as unread
Note that, depending on the Gmail version you have installed, this icon is either on the top or bottom of the page)
4. Your email is now a unread email
