While we’re starting to see renders of the Samsung Galaxy S9 and Samsung Galaxy S9 Plus, live images and videos are yet to really start emerging, so it’s no wonder a recent video purporting to show the larger S9 Plus is gaining attention, but it’s almost certainly a fake.

Originally posted by Slashleaks, the video has already been debunked, with the site updating to say it’s probably a Chinese clone going by the name HDC S9.
