The Galaxy S9 and Galaxy S9+ will be unveiled at a Samsung Unpacked event in Barcelona, Spain on February 25, 2018.

While we don't know much about the phone officially, we've learned a lot about the two devices through a combination of teases and believable leaks. For starters, they'll have the same screen sizes as their Galaxy S8 predecessors — 5.8 inches and 6.2 inches, respectively — but, thanks to a further reduction in bezels, slightly more compact dimensions. They'll also sport the latest Snapdragon 845 processors, while the larger S9+ will feature 6GB of RAM and 128GB of storage compared to just 4GB and 64GB on the regular-sized S9.

Further differentiation will come from the cameras: like the Note 8, the Galaxy S9+ will have two cameras — one 12MP sensor with a variable aperture of ƒ1.5-2.4 and a second 12MP sensor with a fixed aperture — while the regular S9 will have just the one 12MP sensor with a variable aperture. We're also looking at stereo speakers on both devices and improvements to the face unlock/iris scanning biometrics.
