While legend has it that the number 7 has magical qualities, there's no knowing what qualities the S7 has. If we were to guess completely at random:

5.1-inch Super AMOLED display with 2560 × 1440 resolution (576 ppi)

Qualcomm Snapdragon 820 processor with 4 GB RAM + Adreno 530 GPU

12-megapixel rear camera with dual pixel autofocus, 4K video capture; 5-megapixel selfie camera

32 or 64 GB internal storage, expandable via MicroSD card (up to 200 GB additional)

IP68 water resistance rating

Android 6.0 Marshmallow

Since the S7 has never been seen on the internet before, there's no way to know if these educated guesses are right.
