TENAA already added the front and rear renders for the 16Xs, but the specs are not yet in the database. Still word on the street is that the handheld will be powered by the Snapdragon 712 SoC coupled with 6 GB of RAM and up to 128 GB storage, and it will come with a notch-less display plus a triple-cam setup on the back.
