Sorry, but that sounds like it is configured as IMAP on your other devices.
POP3 does not "synchronize" folders. It downloads new emails and either "leaves a copy on the server" or deletes immediately from the server depending on an option setting available in every POP3 client's setup screen.
IMAP, on the other hand, synchronizes the local client's folders with the same folders on the server. Whatever exists on one, exists on the other. Whatever is deleted from one will (normally) be deleted from the other.
Check the mail account settings on your S4 and tablets; more than likely you will find that they are configured for IMAP access.
