Samsung unveiled the latest iteration of its flagship smartphone, debuting the Samsung Galaxy S9 and S9 Plus on Sunday at Mobile World Congress.

The new phones, available March 16, feature improved cameras and a repositioned fingerprint scanner, among other changes. The 12-megapixel camera now has an adjusting aperture, which helps automatically let in more light and can improve photos taken in dark settings. The S9 Plus also features a dual camera lens.

The fingerprint scanner is now below the rear camera, instead of to the right, as it was positioned on the S8. Samsung also added new augmented reality tech to the phones.

The Verge and Engadget have detailed reviews of the new devices.

The unlocked Galaxy S9 will retail for $719.99 or $30 per month for 24 months; the unlocked Galaxy S9 Plus is $839.99 or $35 per month for 24 months. Prices vary depending on carriers, which are offering trade-in deals. Pre-orders start March 2.
