Best: Samsung includes a stunning 5.8-inch display on Galaxy S9 and a 6.2-inch display on Galaxy S9 Plus. Both phones have slightly curved AMOLED screens, with 2,960 x 1,440 pixel resolution displays. Like other Galaxy smartphones, the Galaxy S9 includes an infinity display.
Best: Both theGalaxy S9 and Galaxy S9 Plus keep the 3mm headphone jack -- unlike iPhone X. This means no extra accessories or inconveniences.
Best: Samsung moves the Galaxy S9's fingerprint scanner to below the camera array. On the Galaxy S8, the fingerprint scanner was found to the right of the camera. In ZDNet's review, we found Galaxy S9 fingerprint scanner placement to be much better.
Worst: Just watch out for fingerprints on the back of the all-glass Galaxy S9.
Best: Samsung added stereo speakers to the Galaxy S9 and Galaxy S9 Plus. A bonus for audiophiles, they're tuned by AKG and pump out surround sound supported by Dolby Atmos. Samsung claims sound is 1.4x more powerful than previous Galaxy devices.
Samsung claims Galaxy S9 is the first phone to include adjustable aperture. If the Galaxy S9 is taking a picture in the dark, the lens opens to F1.5 mode to pull in light for a bright and clear photo. In the daylight, the lens shifts to F2.4 mode to help reduce the amount of light filtering into the photo for a sharper look.
Best: Both the Galaxy S9 and Galaxy S9 Plus pack beefy specifications:
RAM and storage
Worst: Samsung includes a button pre-programmed to launch its Bixby smart assistant. The problem is, Bixby's feature set is not as strong as other competitors like Siri and Alexa. You also can't reprogram the button's functionality through official Galaxy S9 settings. However, you can disable the button entirely through Galaxy S9 settings.
Worst: In an attempt to fend off Apple's Animoji, the Galaxy S9 includes AR emoji. From a single selfie, the Galaxy S9's uses machine learning to generate a personalized 3D avatar that looks like you and can mimic movements. Here's early impressions, and they're not great. AR Emoji are compatible with messaging apps that tap Samsung's keyboard.
AR emoji can be shared as GIF or video for non-supported platforms.
