Samsung just sent out invites for an event for next month during which we're likely to hear about a brand new Galaxy device of some sort. 

The invite doesn't say much, but it says it'll be a "Galaxy event" suggesting we'll see a new device from the company's phone lineup. That said, we've already had the Samsung Galaxy Note 9 announcement, so it may be a new lineup of devices.
