15. Galaxy S8 and S8 Plus.
The Galaxy S8 and S8 Plus are “old” phones now that the S9 is released, but Samsung is still selling them for a nice little discount. They’re great phones, but despite the discount, I’d still go for the Galaxy S9 or S9 Plus. The S9 has much better facial/iris recognition, and the fingerprint scanner under the camera is much easier to reach.
