A very recent report from South Korea claimed that the Galaxy Tab S3 was to be the star of MWC for Samsung, instead of the Galaxy S8. Not too long after, Samsung has basically confirmed this is true.
Samsung has just sent a mass email to the media for its press event to take place at MWC in late-February. The event will be taking place on February 26 at 7PM local time (CET). The invitation also teases the Galaxy Tab S3 by showing its lower bezel.
The specs that we know are based off of previous benchmark listings which claim it has a Snapdragon 820 CPU, 4GB of RAM, 32GB of storage, 4GB of RAM, a 13MP rear camera with a 5MP front-facing one, a 9.6-inch 2,048 x 1,535px display, and is said to come in LTE and Wi-Fi variants.
