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

The phones 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 also sport the latest Snapdragon 845 processors, while the larger S9+ will feature 6GB of RAM of storage compared to 4GB on the regular-sized S9. Both phones come with 64GB of storage standard along with options for 128GB and 256GB if you need more storage.

While the standard Galaxy S9 has a single camera, the Galaxy S9+ has two cameras — one 12MP sensor with a variable aperture of ƒ1.5-2.4 and a second 12MP sensor with a fixed aperture. We're also looking at stereo speakers on both devices and improvements to the face unlock/iris scanning biometrics.
